Special Table 2009-531815 Gazette Japanese Unexamined Patent Publication No. 2007-258028 Japanese Unexamined Patent Publication No. 11-31561

In the configuration of Patent Document 1, when the connector is inserted into the pin contact, the insertion / removal force of the connector is generated by the frictional force generated between the pin contact and the contact member. Therefore, if the holding force of the contact member is increased, this frictional force is also increased, and it becomes difficult to insert and remove the connector. On the other hand, if the holding force of the contact member is reduced, the holding force of the connector after being fitted to the pin contact is reduced. Therefore, the configuration of Patent Document 1 has a problem that it is difficult to achieve both reduction of insertion / extraction force and stable holding.

In the configuration of Patent Document 2, after the plug is engaged with the receptacle, it can be stably held by the lock member. Therefore, in the socket contact, it is considered that the holding force (pressure contact force) of the contact member that narrowly holds the pin contact can be reduced to some extent. However, in order to obtain a reliable electrical connection between the pin contact and the contact member, a certain amount of pressure contact force is required in the contact member. Therefore, when the coefficient of friction between the pin contact and the contact member becomes large (for example, when the pin contact or the contact member is tin-plated) or when the number of poles in the multi-pole connector is large, the insertion / extraction force is applied. Increases and it becomes difficult to insert and remove the connector.

In the configuration of Patent Document 3, since the state can be locked after the flat wire is inserted into the connector, it is possible to use a so-called non-insertion / pull-out force type connector that requires almost no force when inserting the flat wire. can. However, two operations, an operation of inserting the flat wire into the connector and an operation of locking the flat wire after insertion, are required, and there is a problem that the operation of connecting the flat wire to the connector becomes complicated.

The present disclosure has been made in view of the above problems, and provides socket parts and connectors for connectors that can easily connect a socket contact to a pin contact and can significantly reduce the insertion / extraction force for the pin contact. The purpose is.

In order to solve the above problems, the socket component for a connector according to the first aspect of the present disclosure is a socket component for a connector having a socket contact connectable to a pin contact, and the socket contact is the pin. It has an operation movable member that is movable by receiving a predetermined operation by the user when connected to the contact, and the socket contact has two holding the pin contact when connected to the pin contact. It has a contact terminal, and at least one of the two contact terminals is subjected to an urging force in a direction of pressure contact with the other contact terminal, and the one contact terminal is connected to the operation movable member. When the movable member receives the predetermined operation, the movable member moves in conjunction with the movable member to reduce the contact pressure between the terminals of the two contact terminals.

According to the above configuration, when the socket contact of the socket component for the connector is connected to the pin contact, the user operates the movable member to make contact between the terminals of the two contact terminals that hold the pin contact. The pressure can be reduced. This allows the socket contact to be connected to the pin contact with the insertion and removal force eliminated or significantly reduced. Further, after joining the socket contact and the pin contact, by releasing the operation of the movable member, the two contact terminals can hold the pin contact and maintain a stable holding state.

Further, in the socket component for a connector, the operation movable member is a lever that can rotate around a support shaft, one end thereof is an operation portion for a user to apply a force, and the other end portion is the one end. It is connected to the contact terminal of the above, and the distance from the support shaft to the end of the operation unit is set to be longer than the distance from the support shaft to the connection point with the one contact terminal. It can be configured.

According to the above configuration, according to the principle of the lever, it is possible to increase the pressure contact force of the contact terminal with respect to the pin contact while reducing the operating force of the movable member to improve the operability.

Further, in the socket component for a connector, a screwless terminal block is formed at an end opposite to the socket contact, and a contact terminal having a leaf spring function in the socket contact and a leaf spring in the screwless terminal block. The contact terminal having a function may be formed of the same leaf spring member.

According to the above configuration, advantages such as reduction in the number of parts in the connector socket parts and ease of assembly can be obtained.

Further, in order to solve the above-mentioned problems, the connector according to the second aspect of the present disclosure is a connector composed of a plug part and a socket part, and the socket part is a socket part for a connector described above. The plug component has a configuration in which the pin contact is housed in a plug housing, the plug housing is provided with a first engaging portion, and the operable movable member is provided with a second engaging portion. In a state where the socket component is fitted to the plug component and the movable member is not subjected to a predetermined operation, the first engaging portion and the second engaging portion engage with each other to cause the plug component. It is characterized in that the fitted state between the socket component and the socket component is maintained.

According to the above configuration, the engagement between the first engaging portion and the second engaging portion maintains the fitted state between the plug component and the socket component, and the socket component can be prevented from coming off. When the socket part is pulled out from the plug part, the engagement between the first engaging portion and the second engaging portion can be easily disengaged by operating the operation movable member.

The socket component for a connector and the connector of the present disclosure are terminals of two contact terminals that narrow the pin contact by the user operating a movable member when connecting the socket contact of the socket component for the connector to the pin contact. It has the effect of reducing the contact pressure between the connectors and significantly reducing the insertion / extraction force.

Hereinafter, embodiments relating to one aspect of the present disclosure will be described with reference to the drawings. FIG. 1 is a perspective view of the connector 10 according to the present embodiment. FIG. 2 is a cross-sectional view of the connector 10 at the fitting position between the pin contact 102 and the socket contact 210. Although FIG. 1 illustrates a case where the connector 10 is a 4-pole multi-pole connector, the number of poles of the connector is not particularly limited. Further, the connector 10 may be a unipolar connector.

The connector 10 is composed of a plug component 100 and a socket component 200. The socket component 200 is an example of the "socket component for a connector" of the present invention. The plug component 100 is composed of a plug housing 101 and a pin contact 102, and is provided on, for example, a circuit board (not shown). In the plug component 100, the pin contact 102 is housed in the space 101a formed in the plug housing 101, and one end of the pin contact 102 (the connection side with the socket contact 210) is exposed in the space 101a. The space 101a is open at least on the insertion side of the socket component 200.

The socket component 200 has a socket contact 210 at one end thereof. Further, in the present embodiment, a configuration in which a screwless terminal block 220 is provided at the other end of the socket component 200 is illustrated. However, the configuration of the other end of the socket component 200 is not limited to this, and may be, for example, a configuration in which an electric wire is directly connected to the other end of the socket component 200.

Further, the configuration of the socket component 200 will be described in more detail. The socket component 200 is roughly composed of a socket body 201 and a lock lever 230. The lock lever 230 is attached to the socket body 201 so as to be rotatable around a support shaft 201a (see FIG. 1) provided on the socket body 201. The lock lever 230 is an example of the "operable movable member" of the present invention.

As shown in FIG. 2, the socket main body 201 includes a socket housing 202, a cover housing 203, a contact member 204, and a leaf spring member 205. That is, the socket main body 201 accommodates the contact member 204 and the leaf spring member 205 in the housing including the socket housing 202 and the cover housing 203.

The contact member 204 is made of a conductive material such as metal, and one end thereof is the first contact terminal 204a in the socket contact 210 and the other end is the third contact terminal 204b in the screwless terminal block 220. The leaf spring member 205 is made of a material having a strong spring property (for example, SUS), one end of which is the second contact terminal 205a in the socket contact 210, and the other end of which is the fourth contact terminal 205c in the screwless terminal block 220. Will be. Further, a hook portion 205b is formed at the tip of the second contact terminal 205a in the leaf spring member 205.

The socket contact 210 in the socket component 200 is configured such that the first contact terminal 204a of the contact member 204 and the second contact terminal 205a of the leaf spring member 205 are arranged to face each other. That is, the connector 10 is connected by fitting the socket component 200 to the plug component 100 and narrowing the pin contact 102 between the first contact terminal 204a and the second contact terminal 205a in the socket contact 210. To. In the socket contact 210, the second contact terminal 205a is urged to be in pressure contact with the first contact terminal 204a by the elastic force of the leaf spring member 205. Further, the first contact terminal 204a may also be a leaf spring and may be urged so as to be in pressure contact with the second contact terminal 205a.

The screwless terminal block 220 in the socket component 200 is configured such that the third contact terminal 204b of the contact member 204 and the fourth contact terminal 205c of the leaf spring member 205 are arranged to face each other. Further, the fourth contact terminal 205c is urged so as to be in pressure contact with the third contact terminal 204b by the elastic force of the leaf spring member 205. Further, the socket housing 202 is provided with a wiring insertion hole 202a and a connection release auxiliary hole 202b. The wiring insertion hole 202a is a hole for inserting the wiring (the stripped electric wire or the rod terminal) connected to the screwless terminal block 220, and the wiring inserted from the wiring insertion hole 202a is the third contact terminal 204b and the third contact terminal 204b. It is connected by sandwiching it with the 4-contact terminal 205c. The connection release auxiliary hole 202b is a hole for inserting a tool such as a screwdriver and separating the fourth contact terminal 205c from the third contact terminal 204b when disconnecting the connection.

The lock lever 230 can rotate around the support shaft 201a by engaging the engagement groove 231 (see FIG. 1) with the support shaft 201a (see FIG. 1) provided on the side surface of the socket body 201. Attached to 201. One end of the lock lever 230 (the upper end in FIG. 2) is an operation unit 232 for the user to apply force. An engaging protrusion 233 is formed at the other end of the lock lever 230 (lower end in FIG. 2), and the engaging protrusion 233 is engaged and connected to the hook portion 205b of the leaf spring member 205. .. Therefore, the lock lever 230 is urged in the direction of arrow A1 shown in FIG. 2 by the elastic force of the leaf spring member 205.

Subsequently, the fitting operation when the socket component 200 is inserted into the plug component 100 and fitted will be described with reference to FIGS. 3 (a) to 3 (c). FIG. 3A shows a state in which the socket component 200 and the plug component 100 before fitting are separated.

FIG. 3B shows a state in which the fitting operation is in progress, and the user holds the socket component 200 so as to sandwich the socket body 201 and the operation portion 232 of the lock lever 230. At this time, the lock lever 230 rotates in the direction of arrow A2 due to the force acting on the operation unit 232. When the lock lever 230 rotates in the direction of arrow A2, the hook portion 205b of the leaf spring member 205 is pulled by the engaging protrusion portion 233, and the first contact terminal 204a of the contact member 204 and the second contact of the leaf spring member 205. The distance between the terminal 205a and the contact terminal is reduced, and the contact pressure between the contact terminals is reduced. Then, by inserting the socket component 200 into the plug component 100 with the first contact terminal 204a and the second contact terminal 205a separated from each other, the pin contact 102, the first contact terminal 204a, and the second contact terminal 205a can be obtained. The frictional force generated between the two can be eliminated (or significantly reduced). That is, the socket component 200 can be inserted into the plug component 100 with an extremely small insertion / extraction force.

After inserting the socket component 200 into the plug component 100, when the user releases the hand, the lock lever 230 rotates in the arrow A1 direction due to the elastic force of the leaf spring member 205 as shown in FIG. 3 (c). .. As a result, the pin contact 102 is sandwiched by the first contact terminal 204a and the second contact terminal 205a. At this time, in addition to the elastic force of the leaf spring member 205, the elastic force of the contact member 204 is combined to generate a pressure contact force between the pin contact 102 and the contact member 204, and the pressure contact force is generated between the pin contact 102 and the contact member 204. Proper electrical connection is obtained. Further, the pin contact 102 can be appropriately held between the first contact terminal 204a and the second contact terminal 205a. When the socket component 200 is removed from the plug component 100, the operation opposite to that at the time of insertion may be performed.

With respect to the lock lever 230, it is preferable that the distance from the support shaft 201a to the end of the operating portion 232 is set to be longer than the distance from the support shaft 201a to the end of the engaging protrusion 233. In this case, according to the principle of the lever, the pressure contact force with respect to the pin contact 102 can be increased while reducing the operation force of the operation unit 232 to improve the operability.

Further, the lock lever 230 and the plug component 100 may be provided with a holding mechanism for preventing the socket component 200 from coming off while the socket component 200 is fitted to the plug component 100. FIG. 4 is a cross-sectional view showing a configuration example of such a holding mechanism. The cross section shown in FIG. 4 is a cross section at a position different from that in FIGS. 2 and 3, and is a cross section corresponding to the formed portion of the first engaging portion 103 (see FIG. 1) formed in the plug housing 101. Is.

As shown in FIG. 4, the first engaging portion 103 is formed on the surface of the plug housing 101 facing the lock lever 230. On the other hand, in the lock lever 230, a second engaging portion 234 is formed on the opposite surface to the plug housing 101 at the other end portion (the end portion on the same side as the engaging protrusion portion 233) with respect to the support shaft 201a. .. Then, in a state where the socket component 200 is fitted to the plug component 100 and the user releases the hand (corresponding to the state corresponding to FIG. 3C), the first engaging portion 103 and the second engaging portion 234 are engaged with each other. By doing so, it is possible to prevent the socket component 200 from coming off. When the socket component 200 is removed from the plug component 100, the engagement between the first engaging portion 103 and the second engaging portion 234 can be easily released by operating the lock lever 230.

As described above, the connector 10 according to the present embodiment has a lock lever 230 that is operated when the socket component 200 and the plug component 100 are fitted, and the second contact terminal of the socket contact 210 is used to operate the lock lever 230. The 205a is linked. Therefore, when the socket component 200 is inserted into the plug component 100, the contact terminals of the socket contact 210 (between the first contact terminal 204a and the second contact terminal 205a) are opened by operating the lock lever 230, and the insertion / removal force is greatly increased. The socket component 200 and the plug component 100 can be fitted in a reduced state. Further, after the socket component 200 and the plug component 100 are fitted together, the lock lever 230 can be released to maintain a stable holding state. As a result, it is possible to obtain a connector 10 that is easy to fit and difficult to disconnect.

In the above description, the socket component 200 illustrates a configuration in which the end opposite to the socket contact 210 is a screwless terminal block 220. The second contact terminal 205a having a leaf spring function in the socket contact 210 and the fourth contact terminal 205c having a leaf spring function in the screwless terminal block 220 are formed on the same leaf spring member 205. However, the present disclosure is not limited to this, and the second contact terminal 205a and the fourth contact terminal 205c may be formed of separate members. However, if the second contact terminal 205a and the fourth contact terminal 205c are formed on the same leaf spring member 205, the number of parts can be reduced and the socket parts 200 can be easily assembled, which is preferable.

Further, in the above description, the case where the leaf spring member 205 is SUS is illustrated, but since the electrical conduction between the socket contact 210 and the screwless terminal block 220 is obtained by the contact member 204, the leaf spring member 205 Does not have to be a conductive material. However, when the leaf spring member 205 is used as a conductive material, not only the contact member 204 but also the leaf spring member 205 can obtain electrical conduction between the socket contact 210 and the screwless terminal block 220, so that the socket component The electrical characteristics at 200 are improved, which is preferable.

Further, in the above description, the connector 10 is composed of the socket component 200 and the plug component 100, and the plug component 100 has a configuration in which the pin contact 102 is housed in the plug housing 101. However, the usage pattern of the socket component 200 is not limited to the form of being fitted with such a plug component 100, and the socket contact 210 can be fitted and used only with the pin contact 102. Is.

Further, FIG. 5 shows a modified example of the connector 10 according to the present disclosure. In the connector 10 shown in FIG. 5, the first contact terminal 204a and the second contact terminal 204c are formed on the same contact member 204 on the socket contact 210 side. The other end of the leaf spring member 205 is configured to apply spring pressure to the second contact terminal 204c from the outside.

In this case, the contact pressure is applied between the first contact terminal 204a and the second contact terminal 204c only by the contact member 204, but the contact pressure is set low only by the contact member 204. A sufficient contact pressure can be obtained by applying the spring pressure from the leaf spring member 205. In the configuration shown in FIG. 5, when the lock lever 230 is operated to separate the other end of the leaf spring member 205 from the second contact terminal 204c, the spring pressure applied by the leaf spring member 205 is released and the contact member is released. Since the contact pressure is only 204, the contact pressure between the contact terminals on the socket contact 210 side can be reduced. In this case, even if the spring pressure applied by the leaf spring member 205 is released, the contact pressure is surely fixed, although the first contact terminal 204a and the second contact terminal 204c of the contact member 204 are not always separated from each other. It will be reduced. As a result, it is possible to obtain a connector 10 in which the pin contact 102 and the socket contact 210 can be easily inserted and removed.

The embodiments disclosed this time are exemplary in all respects and are not grounds for limited interpretation. Therefore, the technical scope of the present disclosure is not construed solely by the embodiments described above, but is defined based on the description of the scope of claims. It also includes all changes within the meaning and scope of the claims.
