Description

The present invention relates to a plug connector for connecting a circuit board. More specifically, the present invention relates to a plug connector including signal terminals that ensure a distance between mounting portions.

Generally, when each board is interconnected, two connectors are used that are connected to each board by a method such as soldering, and the two connectors can be connected to each other. Here, one of the two connectors is a plug connector and the other is a socket connector. The socket connector is also called a receptacle connector. Such plug connectors and socket connectors can be formed by arranging terminals in a molded part. The plug connector and the socket connector can be fastened to each other to form an electrical connector assembly.

As electronic devices continue to get smaller, there is a demand for smaller and thinner connectors. However, there are certain limitations to how small and thin a connector can be by reducing the pitch or making the components smaller.

The technical problem that this invention aims to solve is to realize a low profile (reduced length) connector without reducing the pitch or making the components smaller.

For example, in conventional socket connectors, all mounting parts are usually arranged on the same line with a fixed distance between them. In such cases, in order to make the connector smaller (i.e., to reduce its height), the distance between the mounting parts is reduced, but this causes the problem that the solder that attaches the mounting parts to the board comes into contact with adjacent mounting parts.

In other words, when multiple socket terminals (signal terminals) are electrically insulated from one another, they can transmit the desired signals in a differentiated manner. However, if the spacing (pitch) between signal terminals is reduced in the process of making the connector thinner, as mentioned above, some signal terminals may unintentionally become electrically connected to each other in the process of mounting the connector on a board. This is because even if the signal terminals are precisely arranged with a predetermined small pitch, it is ultimately not possible to follow such a precise pitch during the mounting process, and the solder may unintentionally spread out sideways.

Another problem to be solved is to generate a balanced connection force across the length and width of the connector. This is because if the connection force is biased to one side, not only is it difficult to connect, but the connector may be damaged when disconnected, and there is also a risk that data signals may not be supplied properly.

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those of ordinary skill in the art from the description below.

According to the present invention, a plug connector is solder-mounted on a board and coupled to a mating connector, and includes a molded portion including a base and a wall portion protruding from an upper surface of the base; a power terminal installed at at least one end of the wall portion; and a plurality of signal terminals arranged in the longitudinal direction of the plug connector between the ends of the wall portion; the signal terminals include a base; a first contact portion extending from one end of the base in the width direction of the plug connector toward the board side and electrically connected by contacting with a signal terminal of the mating connector; a second contact portion extending from the other end of the base in the width direction of the plug connector toward the board side and electrically connected by contacting with a signal terminal of the mating connector; a first mounting portion extending from the first contact portion toward the outside of the width direction of the plug connector and solder-mounted on the board; and A second mounting portion extends from the contact portion toward the outside in the width direction of the plug connector and is soldered to the board, the first contact portion has a bent portion that is a locking portion for locking with the mating connector, and the second contact portion does not have a bent portion, the width of the first and second mounting portions is narrower than the width of the first and second contact portions in the length direction of the plug connector, and therefore, between adjacent signal terminals, the distance between the first and second mounting portions is longer than the distance between the first and second contact portions, and when the signal terminals are viewed from the coupling direction of the plug connector, one of the first and second mounting portions is biased toward one end in the length direction of the plug connector, and the other of the first and second mounting portions is biased toward the other end in the length direction of the plug connector.

Preferably, in the longitudinal direction of the plug connector, the width of the first and second mounting parts is formed to be 2/3 or less of the width of the first and second contact parts.

Preferably, in the longitudinal direction of the plug connector, the width of the first and second mounting portions is less than or equal to half the width of the first and second contact portions.

Preferably, the power terminals are installed at both ends of the wall in the length direction of the plug connector, and the signal terminals are installed in a row in the length direction of the plug connector between the power terminals at both ends of the wall.

Preferably, when the signal terminals are arranged in a plurality of rows, the signal terminals are arranged so that, when viewed from the width direction of the plug connector, the first contact portion of one of the signal terminals and the second contact portion of the other signal terminals are simultaneously visible.

Preferably, when the signal terminals are arranged in a plurality of rows, the signal terminals are arranged so that the first contact portions and the second contact portions are seen alternating one by one when viewed from the width direction of the plug connector.

Each embodiment of the technical concept of the present invention has at least the following advantages:

In conventional socket connectors, all mounting parts are usually arranged on the same line with a fixed distance between them. In that case, if the distance between mounting parts is reduced to make the connector smaller (i.e., to reduce its height), a problem occurs in that the solder that attaches the mounting parts to the board comes into contact with adjacent mounting parts.

That is, when multiple socket terminals (signal terminals) are electrically insulated from one another, they can transmit the desired signals in a differentiated manner. However, if the spacing (pitch) between signal terminals is reduced in the process of lowering the profile of the connector, as described above, some signal terminals may unintentionally become electrically connected to one another in the process of mounting the connector on a board. This is because even if the signal terminals are precisely arranged at a constant pitch, they are ultimately unable to follow that precise pitch in the process of mounting on the board, and the solder may unintentionally spread out sideways. The present invention provides an effective means for solving such problems.

In addition, in the present invention, when viewed from the top, the mounting parts are arranged in a zigzag pattern. This allows not only the distance between the mounting parts in the length direction of the connector, but also the distance between the mounting parts in the width direction of the connector (strictly speaking, the diagonal distance) to be increased to some extent. This further reliably prevents unintended connections during soldering.

In addition, in the present invention, when viewed from the side of the connector (i.e., when viewed from the width direction of the connector), the bent portions are present alternately. This configuration provides a balanced coupling force at both ends of the connector in the width direction. A balanced coupling force is also provided along the length of the connector. If the coupling force is biased to one side, not only is coupling difficult, but the connector may be damaged when released from the coupling, and there is also a risk that data signals may not be supplied properly. However, with the configuration of the present invention, such problems of biased coupling force do not occur.

The effects of the present invention are not limited to the examples given above, and many more effects are included within this specification.

The advantages and features of the present invention, as well as the methods for achieving them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be embodied in various different forms. However, the present embodiments are provided to fully disclose the present invention and to fully inform those skilled in the art of the present invention of the scope of the invention, and the present invention is only defined by the scope of the claims. The same reference symbols refer to the same elements throughout the specification.

Figure 1 shows a plug connector 10 and a socket connector 20 according to the present invention.

Figure 1 shows the plug connector 10 and the socket connector 20 before they are joined (fitted together and fastened).

As is common to the plug connector 10 and socket connector 20 shown in FIG. 1, the X1-X2 direction is the length direction of the connector, and the Y1-Y2 direction is the width direction of the connector. The length direction and width direction of the connector are perpendicular to each other. As a variation, the length direction and width direction may not be perpendicular to each other, but having them substantially perpendicular is advantageous in terms of the manufacturing process and ensuring appropriate bonding force.

The Z1-Z2 direction is the height direction of the connector.

The plug connector 10 shown in FIG. 1 can be coupled to the socket connector 20 by being inverted upside down. It goes without saying that the socket connector 20 can also be coupled to the plug connector 10 by being inverted upside down. From the perspective of the plug connector 10, the socket connector 20 can also be called the mating connector, and conversely, from the perspective of the socket connector 20, the plug connector 10 can also be called the mating connector. When the plug connector 10 and the socket connector 20 are mated and the conductive parts come into contact with each other, signals and power can be supplied appropriately.

Figure 2 is a diagram illustrating the plug connector 10 of Figure 1 in further detail.

The plug connector 10 is soldered to a substrate (not shown) and is coupled to a mating connector, the socket connector 20.

The plug connector 10 has a molded portion 100, which includes a base portion 110 and a wall portion 120 protruding from the upper surface of the base portion 110.

The molded portion 100 may be formed as an insulating material including, but not limited to, resin and epoxy.

In FIG. 1, power terminals 200 are provided at both ends of the wall portion 120 (both ends in the X1-X2 direction, which is the length direction of the connector). In FIG. 1, the power terminals 200 are provided at both ends, which is preferable in that it provides a balanced coupling force, but this does not exclude the power terminals 200 being provided at only one end.

The signal terminals 300 are arranged in a row in the length direction (X1-X2 direction) of the plug connector between the ends of the wall portion 120.

The signal terminal 300 includes a base 310, a first contact portion 321, a first mounting portion 331, a second contact portion 322, and a second mounting portion 332.

The first contact portion 321 extends from one end of the base portion 310 in the width direction (Y1-Y2 direction) of the plug connector 10 toward the board side (i.e., in the Z1 direction) and is electrically connected by contacting with the signal terminal of the socket connector 20, which is the mating connector.

The second contact portion 322 extends from the other end of the base portion 310 in the width direction (Y1-Y2 direction) of the plug connector 10 toward the board side (i.e., in the Z1 direction) and is electrically connected by contacting the signal terminal of the socket connector 20, which is the mating connector.

The first mounting portion 331 extends outward in the width direction (Y1-Y2 direction) of the plug connector 10 from the first contact portion 321 and is solder-mounted to a substrate (not shown).

The second mounting portion 332 extends from the second contact portion 322 outward in the width direction (Y1-Y2 direction) of the plug connector 10 and is soldered to a substrate (not shown).

The power terminals 200 are preferably installed at both ends of the wall 120 in the length direction (X1-X2 direction) of the plug connector 10, and the signal terminals 300 are preferably installed in a row between the power terminals 200 at both ends of the wall 120 in the length direction (X1-X2 direction) of the plug connector 10.

For example, although it is not precluded that the signal terminals 300 are arranged in two rows, the present invention is more effective in solving the mounting problem (problem of horizontal/vertical distance between mounting parts) when the signal terminals 300 are arranged in a single row.

In the example of FIG. 2, the power terminals 200 are installed on both ends of the wall portion 120 in the longitudinal direction (X1-X2 direction) of the plug connector 10, and this embodiment is preferable in that it provides a balanced locking force and power supply. However, if necessary, an example in which the power terminals 200 are installed on only one end is also possible.

Depending on the situation, if one does not pay particular attention to the fact that it is a power terminal, but focuses only on the existence of any structure, the power terminal 200 can also be referred to simply as a metal fitting.

The power terminal 200 can input and output power electrical signals, and the signal terminal 300 can input and output data electrical signals.

As an example, the signal terminal 300 may be configured as a PIN that allows a current of 0.3 A, and the power terminal 200 may allow a current of 5 A. The molded part 100 of the plug connector 10 is preferably made of a plastic material, for example, LCP (Liquid Crystal Polymer). The power terminal 200 and the signal terminal 300 of the plug connector 10 are preferably made of a metal material, for example, a copper alloy with gold plating (nickel underlayer).

Figure 3 is a top view of the signal terminal included in the plug connector 10 of Figure 2.

Figure 2 shows the molded part 100, the power terminal 200, and the signal terminal 300, while Figure 3 shows only the signal terminal 300 with the molded part 100 and the power terminal 200 virtually removed.

This is an example where there are four signal terminals 300, and it goes without saying that the number of signal terminals 300 can be changed as necessary.

In the example of FIG. 3, four signal terminals 300 are shown, each of which is preferably of the same shape. However, for ease of explanation, the four signal terminals 300 may be denoted by the reference numerals 300A, 300B, 300C, and 300D, respectively.

In FIG. 3, in the longitudinal direction (X1-X2 direction) of the plug connector 10, the width of the first and second mounting portions 331, 332 is narrower than the width of the first and second contact portions 321, 322, so that between adjacent signal terminals 300, the separation distance D2 between the first and second mounting portions 331, 332 is longer than the separation distance D1 between the first and second contact portions 321, 322.

In the length direction (X1-X2 direction) of the plug connector 10, the width W _S of the first and second mounting parts is preferably 2/3 or less of the width W _L of the first and second contact parts. In this case, the separation distance D2 can be sufficiently secured compared to the separation distance D1. Furthermore, in the length direction (X1-X2 direction) of the plug connector 10, the width W _S of the first and second mounting parts is more preferably 1/2 or less of the width W _L of the first and second contact parts. In this case, the separation distance D2 can be further secured.

Therefore, the side distance (distance in the X1-X2 direction; D2) between the mounting parts connected to the board by soldering is made wider than the side distance (distance in the X1-X2 direction; D1) between the signal terminals, preventing mounting failures. In other words, if the distance between the mounting parts is narrow, the problem of solder penetrating into different types of mounting parts and causing signal failures is solved. This effect solves a problem that frequently occurs especially with modern connectors that have a low profile (small size).

Specifically, in conventional socket connectors, all mounting parts are usually arranged on the same line with a fixed distance between them. In that case, when the distance between mounting parts is reduced to make the connector smaller (i.e., to reduce its height), a problem occurs in that the solder that attaches the mounting parts to the board comes into contact with adjacent mounting parts.

That is, when multiple socket terminals (signal terminals) are electrically insulated from one another, they can transmit the desired signals in a differentiated manner. However, if the spacing (pitch) between signal terminals is reduced in the process of lowering the profile of the connector, as described above, some signal terminals may unintentionally become electrically connected to one another in the process of mounting the connector on a board. This is because even if the signal terminals are precisely arranged at a constant pitch, they are ultimately unable to follow that precise pitch in the process of mounting on the board, and the solder may unintentionally spread out sideways. The present invention provides an effective means for solving such problems.

When the signal terminal 300 is viewed from the connection direction (Z1-Z2 direction) of the plug connector 10, the first and second mounting parts 331, 332 located at one end of the plug connector 10 in the width direction (Y2 direction) are biased toward one end of the plug connector 10 in the length direction (X1 direction), and the first and second mounting parts 331, 332 located at the other end of the plug connector 10 in the width direction (Y1 direction) are biased toward the other end of the plug connector 10 in the length direction (X2 direction).

Figure 4 is a perspective view of the signal terminal in Figure 3.

As with FIG. 3, FIG. 4 shows only the signal terminal 300 with the molded part 100 and the power terminal 200 virtually removed from the molded part 100, power terminal 200, and signal terminal 300 shown in FIG. 2.

This is an example where there are four signal terminals 300, and it goes without saying that the number of signal terminals 300 can be changed as necessary.

As with FIG. 3, FIG. 4 shows four signal terminals 300, each of which is preferably of the same shape, although for ease of explanation, the four signal terminals 300 may be denoted by the reference numerals 300A, 300B, 300C, and 300D, respectively.

The signal terminal 300 has two contact parts, namely, a first contact part 321 and a second contact part 322. The difference between these two is that the first contact part 321 is formed with a bent part 321B, which is a locking part for locking with the mating connector 20, while the second contact part 322 is not formed with a bent part.

However, as shown in FIG. 4, signal terminals 300A and 300B have the same shape but are arranged in different directions. That is, from the perspective of the perspective view of FIG. 4, the first contact portion 321 of signal terminal 300A is visible, and the second contact portion 322 of signal terminal 300B is visible. In other words, the bent portion 321B of signal terminal 300A is visible, but the bent portion of signal terminal 300B is not visible (i.e., it is on the rear surface). Although FIG. 4 is a perspective view, strictly speaking, it would be more accurate to consider it as an assumed side view when viewed from the Y2 direction toward the Y1 direction.

This can be achieved by creating four identical signal terminals 300, and in a side view viewed from Y2 toward Y1, signal terminal 300A is positioned so that bent portion 321B is visible, signal terminal 300B is positioned so that bent portion 321B is visible, signal terminal 300C is positioned so that bent portion 321B is visible, and signal terminal 300D is positioned so that bent portion is not visible.

The reason for this configuration is to balance the bonding force. That is, signal terminal 300A is locked at bent portion 321B in the Y2 direction, signal terminal 300B is locked at bent portion 321B in the Y1 direction, signal terminal 300C is locked at bent portion 321B in the Y2 direction, and signal terminal 300D is locked at bent portion 321B in the Y1 direction, so there are two locking locations in the Y1 direction, two locking locations in the Y2 direction, and when viewed from the X1-X2 direction, they are locked alternately one at a time, and the locations where the bonding force is exerted are determined in a regular and balanced manner.

Of course, this is just one typical example, and some modifications are possible. For example, when viewed from the direction from Y2 to Y1, a similar effect can be obtained by arranging the signal terminals 300A and 300B slightly differently from FIG. 4, with the bent portions 321B visible and the bent portions of the signal terminals 300C and 300D invisible (i.e., on the rear surface). Alternatively, a similar effect can be obtained by arranging the signal terminals 300A and 300D with the bent portions 321B visible and the bent portions of the signal terminals 300B and 300C invisible (i.e., on the rear surface). More generally, when viewed from the direction from Y2 to Y1, the number of signal terminals with visible bent portions 321B and the number of signal terminals with invisible bent portions may be the same.

However, if this is done, the bonding force will not be exerted in a zigzag pattern when viewed from the X1-X2 direction, so it is preferable to use the method shown in Figure 4 whenever possible.

Figure 4 shows an example where there is an even number of signal terminals 300, but when there is an odd number of signal terminals 300, they can be arranged repeatedly in a manner such that when viewed from the direction from Y2 to Y1, the bend 321B of one signal terminal 300 is visible and the bend of an adjacent signal terminal 300 is not visible. Generalizing this further, when there is an odd number of signal terminals, it is preferable that the difference between the number of signal terminals where the bend 321B is visible and the number of signal terminals where the bend is not visible is minimized (i.e., the difference in number is 1) when viewed from the direction from Y2 to Y1.

In other words, when arranging multiple signal terminals 300, it is preferable that the multiple signal terminals are arranged so that the first contact portion 321 of one signal terminal and the second contact portion 322 of another signal terminal are simultaneously visible when viewed from the width direction (Y1-Y2 direction) of the plug connector 10.

More preferably, when arranging the multiple signal terminals 300, the multiple signal terminals 300 are arranged so that, when viewed from the width direction (Y1-Y2 direction) of the plug connector 10, the first contact portions 321 and the second contact portions 322 are seen alternating one by one, as shown in FIG. 4.

For reference, Figure 3 does not clearly show the alternating arrangement (zigzag arrangement) of bent portions 321B due to the nature of being a top view, but Figure 3 has the same arrangement as Figure 4.

Figure 5 is a diagram explaining the power supply terminals.

Referring to FIG. 5, the power terminal includes a base portion 210, a first contact portion 221, a second contact portion 222, a first connecting surface 210C1, a second connecting surface 210C2, mounting portions 231, 232, and a cutout portion 200C.

Each will be explained below.

The first contact portion 221 extends from one end (e.g., in the Y2 direction) of the base portion 210 in the width direction (Y1-Y2 direction) of the plug connector 10 toward the board side (not shown) (i.e., in the Z1 direction) and is electrically connected by contacting the power terminal of the socket connector 20, which is the mating connector.

The second contact portion 222 extends from the other end (e.g., in the Y1 direction) of the base portion 210 in the width direction (Y1-Y2 direction) of the plug connector 10 toward the board side (not shown) (i.e., in the Z1 direction) and is electrically connected by contacting the power terminal of the socket connector 20, which is the mating connector.

The first connecting surface 210C1 connects the base 210 and the first contact portion 221. The second connecting surface 210C2 connects the base 210 and the second contact portion 222. Although not limited thereto, it is preferable that the power terminal 200 is manufactured by bending a single metal plate, and therefore the first connecting surface 210C1-base 210-second connecting surface 210C2 can be regarded as a single metal plate that is connected to each other and bent.

The mounting portions 231 and 232 extend from the first contact portion 221 and the second contact portion 222, respectively, to the outside in the width direction of the plug connector 10. The outside in the width direction means that the mounting portion 231 extending from the first contact portion 221 extends in the Y2 direction, and the mounting portion 232 extending from the second contact portion 222 extends in the Y1 direction. As will be described later, this is an explanation for the power terminal 200 shown in FIG. 5 (i.e., the power terminal installed at the end in the X2 direction), and the positional relationship may change with respect to other power terminals 200 in the X1 direction as in FIG. 2 (or FIG. 6 described later), even if the power terminals have the same shape.

The mounting sections 231 and 232 are then soldered to a substrate (not shown).

The cutout portion 200C is formed by cutting a portion where the base portion 210, the first connecting surface 210C1, and the contact portion 221 are connected.

As shown in FIG. 5, it is preferable that the cutout 200C is not formed on the second connecting surface 210C2 (i.e., not formed on the portion where the base 210, the second connecting surface 210C2, and the second contact portion 222 are connected), but is formed only on the first connecting surface 210C1 (i.e., formed only on the portion where the base 210, the first connecting surface 210C1, and the first contact portion 221 are connected). This is because, due to the shape of the cutout 200C described above, it is expected that an elastic force will be exerted when an external force is applied during coupling. If the cutout 200C is formed on the entire first connecting surface 210C1 and the second connecting surface 210C2, the strength of the coupling may be reduced below the required level.

Also, as shown in Figure 5, the cutout 200C is formed so that the inside in the longitudinal direction of the plug connector 10 is open. For example, unlike Figure 5, if the cutout is closer to the X2 direction but the inside (i.e., the X1 direction of the first connecting surface 210C1 in Figure 5) is closed, such a cutout can provide a certain degree of elasticity, but there is a risk that the elasticity will be less than necessary.

The power terminal 200 further includes a third contact portion 223 that extends toward the substrate (not shown) (i.e., in the Z1 direction) at the outer end (X2 direction) in the longitudinal direction of the plug connector 10. The third contact portion 223 provides protection and contact for the end when mated with the mating connector 20.

The implementation sections 231 and 232 are described in more detail below.

The mounting portion 231 extending from the first contact portion 221 has a first inner mounting portion 231I and a first outer mounting portion 231O, and the mounting portion 232 extending from the second contact portion 222 has a second inner mounting portion 232I and a second outer mounting portion 232O.

The first and second inner mounting portions 231I, 232I are formed on the inner side in the length direction of the plug connector 10 (i.e., the X1 direction in FIG. 5), and the first and second outer mounting portions 231O, 232O are formed on the outer side in the length direction of the plug connector 10 (i.e., the X2 direction in FIG. 5).

In the width direction (Y1-Y2 direction) of the plug connector 10, the dimension W _I of the first inner mounting portion 231I is larger than the dimension W _O of the first outer mounting portion 231O, and similarly, in the width direction (Y1-Y2 direction) of the plug connector 10, the dimension W _I of the second inner mounting portion 232I is larger than the dimension W _O of the second outer mounting portion 232O.

In addition, in the longitudinal direction (X1-X2 direction) of the plug connector 10, the dimension L _I of the first inner mounting portion 231I is smaller than the dimension L _O of the first outer mounting portion 231O, and similarly, in the longitudinal direction (X1-X2 direction) of the plug connector 10, the dimension L _I of the second inner mounting portion 232I is smaller than the dimension L _O of the second outer mounting portion 232O.

According to this relationship, the areas ( _WI x _LI , _WO x _LO ) of mounting parts 231I, 231O, 232I, 232O soldered to the board are approximately similar to each other, so that approximately similar mounting forces (fixing forces) can be obtained for the four mounting parts of one power terminal 200, resulting in the effect of obtaining a well-balanced fixing force. Of course, it is not necessary to exactly satisfy the relationship _WI x _LI = _WO x _LO , and it is sufficient that approximately similar mounting areas are obtained by satisfying the magnitude relationship of _WI , _LI , _WO , _LO described above.

The power terminal 200 shown in FIG. 5 is preferably symmetrical (i.e., symmetrical in the Y1-Y2 direction) except for the area where the cutout portion 200C is located.

In addition, in FIG. 5, the dimensions of the inner mounting portions 231I, 232I are smaller than those of the outer mounting portions 231O, 232O when viewed in the length direction of the plug connector 10, and the dimensions of the inner mounting portions 231I, 232I are larger than those of the outer mounting portions 231O, 232O when viewed in the width direction of the plug connector 10. However, it is also possible to deform the inner mounting portions 231I, 232I so that the dimensions of the inner mounting portions 231I, 232I are larger than those of the outer mounting portions 231O, 232O when viewed in the length direction of the plug connector 10, and so that the dimensions of the inner mounting portions 231I, 232I are smaller than those of the outer mounting portions 231O, 232O when viewed in the width direction of the plug connector 10. However, in order for the elasticity of the cutout 200C to be fully exerted, it is more advantageous for the dimensions of the inner mounting parts 231I, 232I to be smaller than the outer mounting parts 231O, 232O when viewed in the length direction of the plug connector 10, as shown in FIG. 5, than for the dimensions of the inner mounting parts 231I, 232I to be larger than the outer mounting parts 231O, 232O when viewed in the length direction of the plug connector 10.

Figure 6 is the same as Figure 2, but is a diagram to explain the positional relationship of the two power terminals 200.

Two power terminals 200 are shown in FIG. 6, and the power terminal 200 at the end in the X2 direction; 200A is the power terminal in the same direction as the one shown in FIG. 5.

In FIG. 6, the power terminal 200; 200B at the end in the X1 direction has the same shape as the power terminal 200A, but due to the different arrangement direction, it can be seen that the position and direction of the cutout portion 200C are different from those of the power terminal 200A.

That is, the power supply terminal 200 includes a first power supply terminal 200A installed at one end (e.g., X2 direction) of the wall portion 120 in the longitudinal direction (X1-X2 direction) of the plug connector 10, and a second power supply terminal 200B installed at the other end (e.g., X1 direction) of the wall portion 120 in the longitudinal direction of the plug connector 10.

The cutout 200C of the first power terminal 200A is located at one end (e.g., in the Y2 direction) of the plug connector 10 in the width direction (Y1-Y2 direction), and the cutout 200C of the second power terminal 200B is located at the other end (e.g., in the Y1 direction) of the plug connector 10 in the width direction (Y1-Y2 direction).

The signal terminals 300 are arranged in a row in the longitudinal direction of the plug connector 10 between the power terminals 200A and 200B at both ends of the wall portion 120.

In addition, the first contact portion 221 and the second contact portion 222 are formed with locking portions 200L1, 200L2, and 200L3 for engaging with the power terminal of the mating connector 20.

Specifically, the locking portion includes a first locking portion 200L1 formed on the first contact portion 221, a second locking portion 200L2 formed on the second contact portion 222, and a third locking portion 200L3.

In FIG. 5, the first locking part 200L1 is visible, but the second locking part 200L2 and the third locking part 200L3 are not visible. However, by referring to FIG. 6, the first to third locking parts 200L1, 200L2, and 200L3 can be seen.

The first locking portion 200L1 and the third locking portion 200L3 are formed on the outer side in the length direction of the plug connector 10 (i.e., the X2 direction for the power terminal 200A and the X1 direction for the power terminal 200B), and the second locking portion 200L2 is formed on the inner side in the length direction of the plug connector 10.

That is, although not limited thereto, it is preferable that the first power terminal 200A and the second power terminal 200B have the same shape, and the difference seen in FIG. 6 is due to the difference in the arrangement direction. Due to this shape, the cutout portion 200C appropriately provides elastic force, and at the same time, the three locking portions in the Y2 direction (i.e., the locking portions 200L3, 200L2 of the power terminal 200B and the locking portion 200L1 of the power terminal 200A) exert a binding force at three points, and the three locking portions in the Y1 direction (i.e., the locking portions 200L3, 200L2 of the power terminal 200A and the locking portion 200L1 of the power terminal 200B) also exert a binding force at three points, so that the binding force can be balanced in the width direction.

In FIG. 6, the first power terminal 200A has a cutout 200C in the Y2 direction, and the second power terminal 200B has a cutout 200C in the Y1 direction, but as another example, it is of course possible for the first power terminal 200A to have a cutout 200C in the Y1 direction, and the second power terminal 200B to have a cutout 200C in the Y2 direction.
