Description

The present invention relates to a connector unit having a first connector and a second connector that are fitted together.

Conventionally, connector units have been proposed that electrically connect a terminal and a mating terminal in a state of being pressed into contact with each other. For example, a terminal used in this type of connector unit is a terminal (so-called a clip terminal) that has an overall U-shape so that the mating terminal is sandwiched between a pair of contact parts. Clip terminals are used, for example, in service plugs that are installed in electric vehicles, hybrid vehicles, etc., and that are used to disconnect the high-voltage battery and the on-board circuit during maintenance, etc. (see, for example, Patent Document 1).

JP 2017-079141 A

In the connector unit using the clip terminal described above, the clip terminal is generally held in one housing, and a thin-plate terminal as a mating terminal to which the clip terminal is electrically connected is pressed into and fixed in the other housing. When the thin-plate terminal is pressed into, a plurality of press-in protrusions that sandwich the thin-plate terminal in the plate thickness direction may be provided on the other housing. For example, the thin-plate terminal may be held by three press-in protrusions so that the center part in the width direction of the thin-plate terminal is pressed to one side in the plate thickness direction, and both side parts in the width direction of the thin-plate terminal are pressed to the other side in the plate thickness direction (so-called three-point press-in). In this case, due to the external force exerted on the thin-plate terminal by each press-in protrusion, the thin-plate terminal may be deformed so as to be curved in the plate thickness direction. When the thin-plate terminal is curved, the contact load at the contact point between the clip terminal and the thin-plate terminal becomes larger or smaller than the design value (i.e., the contact load varies). Such variations in contact load can reduce the reliability of the electrical connection between the terminals, so it is desirable to suppress them as much as possible.

The present invention was made in consideration of the above-mentioned circumstances, and its purpose is to provide a connector unit that provides highly reliable electrical connections between terminals.

In order to achieve the above-mentioned object, the connector unit according to the present invention is characterized by the following [1] to [3].
[1]
A connector unit including a first connector and a second connector that are fitted together,
The first connector is
a pair of first terminals each having a plate-like portion having a plate shape extending along a fitting direction between the first connector and the second connector and a protrusion portion protruding in a plate thickness direction from the plate-like portion and extending in a direction intersecting the fitting direction; and a first housing having a press-fit protrusion portion protruding so as to press each of the pair of first terminals in the plate thickness direction,
the pair of first terminals are disposed in the first housing so as to face each other with a gap therebetween in an opposing direction that intersects with the fitting direction and is parallel to the plate thickness direction,
the protrusion portion of each of the pair of first terminals protrudes outward from the plate-shaped portion in the opposing direction and extends in a width direction intersecting the fitting direction and the opposing direction,
the first housing has, as the press-fit protrusions, a first protrusion that presses a central portion in the width direction of the plate-like portion of each of the pair of first terminals inward in the opposing direction, and a pair of second protrusions that press both side portions in the width direction of the plate-like portion of each of the pair of first terminals outward in the opposing direction,
The second connector is
a pair of second terminals in contact with the protrusions of the pair of first terminals to electrically connect them, a connecting portion that electrically connects the pair of second terminals, and a second housing that holds the pair of second terminals and the connecting portion,
It is a connector unit.
[2]
In the connector unit described in the above [1],
The protrusions of each of the pair of first terminals are
At least some of the protruding surfaces are flat;
Each of the pair of second terminals is
The flat surface extends along the flat protruding surface of the protrusion portion at a location where the protrusion portion contacts the protrusion portion.
It is a connector unit.
[3]
A connector unit including a first connector and a second connector that are fitted together,
The first connector is
a pair of first terminals each having a plate-like portion having a plate shape extending along a fitting direction between the first connector and the second connector and a protrusion portion protruding in a plate thickness direction from the plate-like portion and extending in a direction intersecting the fitting direction; and a first housing having a press-fit protrusion portion protruding so as to press each of the pair of first terminals in the plate thickness direction,
The second connector is
a pair of second terminals in contact with the protrusions of the pair of first terminals to electrically connect them, a connecting portion that electrically connects the pair of second terminals, and a second housing that holds the pair of second terminals and the connecting portion,
Each of the pair of first terminals is
Further comprising an auxiliary protrusion portion protruding from the plate-shaped portion in the plate thickness direction and extending in a direction intersecting the protrusion portion.
It is a connector unit.

According to the connector unit of the configuration of [1] above, the first terminal has a protrusion protruding from the plate-like portion and extending in a direction intersecting the mating direction. In addition to being used as a contact point with the second terminal, this protrusion has the function of improving the bending rigidity of the first terminal in the direction of bending the protrusion. Therefore, compared to a case where such a protrusion is not present, when the first terminal is pressed into the first housing so as to be in pressure contact with the press-fit protrusion provided on the first housing, even if an external force is applied from the press-fit protrusion to the plate-like portion or protrusion of the first terminal in the plate thickness direction (i.e., the direction of bending the protrusion), bending of the first terminal can be suppressed. Furthermore, since the protrusion of the first terminal is also used as a contact point with the second terminal, the first terminal can be prevented from becoming larger and the structure can be made more complicated (and thus the connector unit can be prevented from becoming larger) compared to a case where a protrusion for reinforcement is separately provided. In this way, the connector unit of this configuration has excellent reliability of electrical connection between the terminals.

According to the connector unit of the configuration [2] above, the second terminal has a flat surface that extends along the flat protruding surface of the ridge portion of the first terminal at the location where it contacts this flat protruding surface. Therefore, the protruding surface of the ridge portion of the first terminal and the flat surface of the second terminal are in surface contact, and the contact area between the first terminal and the second terminal can be made larger than when the second terminal has a curved surface at this location. This further improves the reliability of the electrical connection between the terminals.

According to the connector unit of the configuration [3] above, the first terminal has a protrusion extending in a direction intersecting the mating direction, as well as an auxiliary protrusion extending in a direction intersecting the protrusion. This allows both the protrusion and the auxiliary protrusion to be used as contacts with the second terminal, further improving the reliability of the electrical connection between the terminals.

In this way, the present invention can provide a connector unit that provides highly reliable electrical connections between terminals.

The present invention has been briefly described above. The details of the present invention will be further clarified by reading the following detailed description of the invention with reference to the accompanying drawings.

<Embodiment>
Hereinafter, a connector unit 1 according to an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, the connector unit 1 includes a first connector 2 and a second connector 3. When the first connector 2 and the second connector 3 are mated, a terminal 20 (see Figs. 2 and 4) accommodated in the first connector 2 and a terminal 40 (see Figs. 2 and 4) accommodated in the second connector 3 are electrically connected.

The connector unit 1 is typically mounted on electric vehicles, hybrid vehicles, etc., and is used as a service plug to ensure the safety of workers by disconnecting the on-board high-voltage battery from the on-board circuit during maintenance, etc. For ease of explanation, the following definitions are used to refer to the "forward/rearward direction," "left/right direction," "up/down direction," "front," "rear," "left," "right," "up," and "down" as shown in Figures 1 to 8. The "forward/rearward direction," "left/right direction," and "up/down direction" are mutually perpendicular.

As shown in Figures 1 and 2, the first connector 2 includes a housing 10 and a pair of terminals 20 housed in the housing 10. The second connector 3 includes a housing 30 and a pair of terminals 40 housed in the housing 30. Below, we will first explain each part that makes up the first connector 2 in order.

First, the housing 10 will be described. The resin housing 10 has a generally rectangular parallelepiped shape that is long in the front-to-rear direction, as shown in Figs. 1 to 3. A pair of mating plates 11 that protrude upward and face each other with a gap in the left-to-right direction are provided on the upper part of the housing 10, as shown in Fig. 2. Each mating plate 11 has a generally rectangular flat plate shape that extends in the front-to-rear and up-to-down directions and is long in the front-to-rear direction. The pair of mating plates 11 are inserted (fitted) into a pair of mating recesses 31 of the housing 30, which will be described later.

The housing 10 includes a substantially flat partition wall 13 that crosses the space 12 between the pair of mating plates 11 in the front-rear direction so as to divide the space 12 in two in the left-right direction (see FIG. 2). The partition wall 13 is inserted into a storage section 32 (see FIG. 2) of the housing 30, which will be described later.

The housing 10 has a pair of through holes 14 extending in the vertical direction so as to face both left and right end walls of the partition wall portion 13 (see FIG. 2). Each through hole 14 has a generally rectangular parallelepiped shape that extends in the front-rear and up-down directions and is long in the front-rear direction. The main body portions 21 (see FIGS. 4 and 5) of the pair of terminals 20, which will be described later, are inserted (press-fitted) into the pair of through holes 14.

As shown in FIG. 2, a pair of engagement protrusions 15 that protrude inward in the left-right direction (i.e., into the through hole 14) are formed on the inner wall (inner wall extending in the front-rear and up-down directions) on the outer left-right direction that defines the upper end of each through hole 14, and are spaced apart in the front-rear direction. The engagement protrusions 15 of the pair of through holes 14 engage with engagement holes 24 (see FIGS. 4 and 5) of the pair of terminals 20, which will be described later.

As shown in FIG. 3, on the inner wall (inner wall extending in the front-rear and up-down directions) on the inner side in the left-right direction that defines each through hole 14, two protrusions 16 that protrude outward in the left-right direction (i.e., into the inside of the through hole 14) and extend in the up-down direction are formed side by side with a gap in the front-rear direction. Similarly, on the inner wall (inner wall extending in the front-rear and up-down directions) on the outer side in the left-right direction that defines each through hole 14, a single protrusion 17 that protrudes inward in the left-right direction (i.e., into the inside of the through hole 14) and extends in the up-down direction is formed in the center in the front-rear direction. The protrusions 16 and 17 function to press-fit and fix the main body 21 of the terminal 20 inserted into the through hole 14 (see FIG. 3(b)).

Next, the pair of terminals 20 will be described. As shown in Figs. 2 and 4, the pair of terminals 20 are arranged in the housing 10 so as to face each other with a gap in the left-right direction. As shown in Fig. 5, each metal terminal 20 has a roughly rectangular flat body portion 21 that extends in the front-rear and up-down directions and is long in the front-rear direction, a flat extension portion 22 that extends downward from the body portion 21, and a stud bolt portion 23 that protrudes leftward (to one side in the plate thickness direction of the terminal 20) from the extension end of the extension portion 22.

Of the pair of left and right terminals 20, the extension portion 22 of the left terminal 20 extends downward from the front end of the main body 21, and the extension portion 22 of the right terminal 20 extends downward from the rear end of the main body 21. Of the pair of left and right terminals 20, the stud bolt portion 23 of one terminal 20 is electrically connected to the vehicle's high-voltage battery, and the stud bolt portion 23 of the other terminal 20 is electrically connected to the vehicle's circuitry.

In each terminal 20, a pair of engagement holes 24 penetrating in the left-right direction (the plate thickness direction of the terminal 20) are formed in the main body 21 in correspondence with a pair of engagement protrusions 15 (see FIG. 2) of the housing 10, so as to be aligned at a distance in the front-rear direction. A protrusion 25 that protrudes outward in the left-right direction is formed on the outer left-right end surface of the upper side of the pair of engagement holes 24 of the main body 21, so as to extend in the front-rear direction. The top surface of the protrusion 25 is a flat surface 26 that extends in the front-rear and up-down directions and is long in the front-rear direction (see FIG. 6(b)). The protrusion 25 functions as a contact point with the terminal 40 (see FIGS. 2 and 4).

The main body 21 of the terminal 20, which is a plate-like body, has such a protrusion 25, and therefore has superior bending rigidity in the direction in which the protrusion 25 is curved, compared to a plate-like body that does not have such a protrusion.

Furthermore, a hemispherical protrusion 27 that protrudes outward in the left-right direction is formed on the outer end surface of the main body 21 between the pair of engagement holes 24. The protrusion 27 comes into pressing contact with the protrusion 17 of the housing 10 (see FIG. 3(b)).

The main body 21 of each terminal 20 is inserted from below into the through hole 14 of the housing 10 (see Figs. 2 and 3). As shown in Fig. 3(b), this insertion proceeds while the inner end faces in the left and right direction of the main body 21 are in pressing contact (rubbing) with the pair of protrusions 16, and while the protrusions 27 of the main body 21 are in pressing contact (rubbing) with the protrusions 17 (i.e., pressed in by so-called three-point contact). This insertion (press-in) continues until the upper end of the main body 21 is exposed from the upper end of the through hole 14 and the pair of engagement protrusions 15 of the housing 10 are locked into the pair of engagement holes 24 of the terminal 20. When the pair of engagement protrusions 15 of the housing 10 are locked into the pair of engagement holes 24, the press-in of the pair of terminals 20 into the housing 10 is completed, and the first connector 2 is completed.

Here, due to the three-point contact press-fit, an external force is applied from the protrusions 16 and 17 to the main body 21 and the protrusion 25 of the terminal 20 in a direction that bends the center of the front-to-rear direction inward in the left-to-right direction. However, due to the above-mentioned function of improving the bending rigidity of the protrusion 25, it is possible to suppress the deformation of the main body 21 and the protrusion 25 of the terminal 20 so that they are curved.

When the pair of terminals 20 have been press-fitted into the housing 10, as shown in Figures 1 and 2, the pair of terminals 20 are fixed to the housing 10 so as to face each other with a gap in the left-right direction. The upper regions including the protruding portions 25 of the pair of main body portions 21 are exposed in the space 12 so as to sandwich the partition portion 13 in the left-right direction, and the pair of stud bolt portions 23 are exposed to the outside below the housing 10 so as to be lined up separately in the front-rear direction. Above, each component that constitutes the first connector 2 has been described. Next, each component that constitutes the second connector 3 will be described in order.

First, the housing 30 will be described. As shown in Figs. 1 and 2, the resin housing 30 has a generally rectangular parallelepiped shape that is long in the front-to-rear direction. A pair of mating recesses 31 are formed on the underside of the housing 30, corresponding to the pair of mating plate portions 11 of the housing 10. Each mating recess 31 is a hole that is recessed upward and opens downward, and has a generally rectangular parallelepiped shape that extends in the front-to-rear and up-down directions and is long in the front-to-rear direction.

A storage section 32 for storing a pair of terminals 40 (see Figures 4 and 5) is formed on the underside of the housing 30 between the pair of mating recesses 31. The storage section 32 is a hole that is recessed upward and opens downward, and has a roughly rectangular shape that extends in the front-to-back and up-down directions and is long in the front-to-back direction.

Next, the pair of terminals 40 will be described. As shown in Figures 2, 4, and 5, the pair of terminals 40 are arranged inside the storage section 32 so as to be spaced apart in the front-to-rear direction. As shown in Figure 5, each metal terminal 40 has a flat base 41 extending in the front-to-rear and left-to-right directions, and a pair of flat extensions 42 extending downward from both left and right ends of the base 41. In this example, the pair of extensions 42 are inclined so that the distance between them becomes narrower as they move away from the base 41. The pair of extensions 42 are elastically deformable outward in the left-to-right direction.

A pair of bent portions 43 are provided at the extending ends of the pair of extending portions 42, which are bent in directions away from each other. The top surface of each bent portion 43 is a flat surface 44 that extends in the front-rear and up-down directions and is long in the front-rear direction. The bent portion 43 (flat surface 44) functions as a contact point with the terminal 20 (see Figures 2 and 4).

The pair of terminals 40 are inserted and fixed into the accommodating portion 32 of the housing 30 (see FIG. 2) so that they are spaced apart in the front-to-rear direction (see FIG. 4 and FIG. 5). This completes the second connector 3. When the pair of terminals 40 have been fixed to the housing 30, as shown in FIG. 2, the pair of extensions 42 of each terminal 40 are exposed within the accommodating portion 32. The above describes each of the components that make up the second connector 3.

Next, the mating operation between the first connector 2 and the second connector 3 will be described. To mate the first connector 2 and the second connector 3, first, the housing 10 and the housing 30 are positioned so that the housing 30 is located above the housing 10.

Next, the housing 10 and the housing 30 are brought closer to each other in the vertical direction, and the first connector 2 and the second connector 3 are mated so that the pair of mating plate portions 11 are inserted into the pair of mating recesses 31 and the bulkhead portion 13 (and the main body portion 21 of the pair of terminals 20) are inserted into the accommodating portion 32. This mating proceeds as the protrusion portions 25 of the pair of terminals 20 push the pair of bent portions 43 of each of the pair of terminals 40 outward in the left-right direction. Then, when the flat surfaces 26 of the pair of protrusion portions 25 come into surface contact with the pair of flat surfaces 44 of each of the pair of terminals 40 while pressing against each other (Figure 6), this mating is completed and the connector unit 1 is obtained.

The bending rigidity of the protrusion 25 described above is improved, which prevents the protrusion 25 of the terminal 20 from deforming in a curved manner. This makes it extremely unlikely that the contact load at the surface contact point between the flat surface 26 of the protrusion 25 and the flat surface 44 of the bent portion 43 will be too large or too small relative to the design value (i.e., variation in the contact load will occur), and this can prevent a decrease in the reliability of the electrical connection between the terminals 20 and 40.

When the first connector 2 and the second connector 3 are fully engaged, as shown in FIG. 2, each of the protrusions 25 of the pair of terminals 20 is pressed into contact with the corresponding bent portion 43 of each of the pair of terminals 40 and electrically connected. As a result, the vehicle-mounted high-voltage battery connected to the stud bolt portion 23 of one terminal 20 and the vehicle-mounted circuit connected to the stud bolt portion 23 of the other terminal 20 are electrically connected via the pair of terminals 40.

In this way, when vehicle maintenance is performed with the first connector 2 and the second connector 3 completely engaged, the first connector 2 is removed from the second connector 3. This cuts off the connection between the terminals 20 and 40, and cuts off the electrical connection between the pair of stud bolt portions 23, thereby cutting off the connection between the high-voltage battery and the on-board circuit. As a result, the safety of the maintenance worker is ensured.

<Action and Effects>
As described above, according to the connector unit 1 of the present embodiment, the terminal 20 has the protrusion 25 that protrudes from the main body 21 and extends in a direction (front-rear direction) intersecting the fitting direction, and therefore has superior bending rigidity in the direction of curving the protrusion 25 compared to a plate-like body that does not have such a protrusion. Therefore, when the terminal 20 is pressed into the housing 10 so as to be in pressing contact with the protrusions 16 and 17 provided on the housing 10, even if an external force in the plate thickness direction is applied from the protrusions 16 and 17 to the main body 21 or the protrusion 25 of the terminal 20, the action of the protrusion 25 can suppress deformation of the terminal 20 so as to be curved. Furthermore, since the protrusion 25 of the terminal 20 is also used as a contact point with the terminal 40, it is possible to avoid an increase in size of the terminal 20 and a complex structure (and thus an increase in size of the connector unit 1, etc.) compared to a case in which a protrusion 25 for reinforcement is separately provided. Therefore, the connector unit 1 of the present embodiment has excellent reliability of electrical connection between the terminals 20 and 40.

Furthermore, terminal 40 has a flat surface 44 that extends along the flat protruding surface (flat surface 26) of protruding portion 25 of terminal 20 at the location where it contacts this protruding surface (flat surface 26). Therefore, the protruding surface (flat surface 26) of protruding portion 25 of terminal 20 and flat surface 44 of terminal 40 are in surface contact, and the contact area between protruding portion 25 of terminal 20 and terminal 40 can be made larger than when terminal 40 has a non-flat curved surface at this location. This further improves the reliability of the electrical connection between terminals 20, 40.

<Other Aspects>
The present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiments, and appropriate modifications, improvements, etc. are possible. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

For example, in the above embodiment, a flat surface 26 is formed on the top of the protrusion 25 of the terminal 20, and a flat surface 44 is formed on the top of the bent portion 43 of the terminal 40, and when the first connector 2 and the second connector 3 are fully mated, the flat surfaces 26, 44 are in surface contact while pressing against each other (see FIG. 6). In contrast, the top of the protrusion 25 of the terminal 20 may be curved, the top of the bent portion 43 of the terminal 40 may be curved, or both the top of the protrusion 25 of the terminal 20 and the top of the bent portion 43 of the terminal 40 may be curved.

Furthermore, in the above embodiment, the main body 21 of the terminal 20 is formed with a protrusion 25 extending in the front-rear direction, and only the protrusion 25 functions as a contact point with the terminal 40. In contrast, as shown in FIG. 7, the main body 21 of the terminal 20 may be further formed with a plurality of auxiliary protrusions 28 extending in both the up and down directions from a plurality of points in the front-rear direction of the protrusion 25 in addition to the protrusion 25, and the auxiliary protrusions 28 may also function as a contact point with the terminal 40 in addition to the protrusion 25. According to the example shown in FIG. 7, both the protrusion 25 and the auxiliary protrusion 28 can be used as a contact point with the terminal 40, so that the reliability of the electrical connection between the terminals 20 and 40 can be further improved.

Furthermore, in the above embodiment, the pair of extensions 42 of the terminal 40 protrude from the base 41 so that the gap between the pair of extensions 42 in the left-right direction gradually narrows. In contrast, in the example shown in FIG. 8, the pair of extensions 42 of the terminal 40 protrude parallel to each other from the base 41, and the extension ends of the pair of extensions 42 do not have bent portions 43 (see FIG. 8). Therefore, as shown in FIG. 8, when the first connector 2 and the second connector 3 are fully engaged, the flat surface 26 of the protruding portion 25 of the terminal 20 is in surface contact with the inner surface (flat surface) 44 of the extension end of the extension portion 42 of the terminal 40. According to the example shown in FIG. 8, the shape of the terminal 40 can be simplified without compromising the reliability of the electrical connection between the terminals 20 and 40, and the productivity of the terminal 40 (and therefore the productivity of the connector unit 1) can be improved.
