Disclosure of Invention
Technical problem to be solved by the invention
The screw-free terminal block (connector) disclosed in patent document 1 or 2 has a terminal block at one end and a socket contact at the other end. The terminal block holds the inserted harness by two contact terminals, and the socket contact holds the pin contact by two contact terminals.
In the structure disclosed in patent document 1 or 2, one contact terminal of the terminal block and one contact terminal of the socket contact are formed at each end of the same contact member. Therefore, the electrical conduction between the harness inserted into the terminal block and the pin contact inserted into the socket contact can be obtained by the contact member.
On the other hand, the other contact terminal of the terminal block is a plate spring member (e.g., SUS spring) having high elasticity (large spring constant) so as to stably hold the electric wiring. In addition, copper materials for springs (e.g., phosphor bronze) having high electrical conductivity are generally used for both contact terminals of the socket contact. In addition, both contact terminals of the socket contact are formed on the same contact member.
In the socket contact, in order to ensure contact reliability (to obtain sufficient electrical conduction with respect to the pin contact), it is important to apply a high contact pressure between both contact terminals. In the structure disclosed in patent document 1 or 2, the contact terminals of both the socket contacts are made of copper material for spring, but the copper material for spring is good in electrical conductivity, but is inferior to SUS or the like in elasticity, and it is difficult to increase the contact pressure between the contact terminals. In addition, in order to obtain higher contact reliability according to the user's demand, a socket contact in which the contact pressure between contact terminals is increased is demanded.
Patent document 1 also discloses a structure in which a contact pressure between contact terminals of socket contacts is increased by adding a component, but this structure has a problem such as an increase in the number of components.
The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to provide a screw-free terminal block of a connector type having a socket contact capable of obtaining high contact reliability without increasing the number of parts.

In addition, a connector-type screw-free terminal block according to a second aspect of the present disclosure has a socket contact connectable to a pin contact at one end and a screw-free terminal block at the other end, and is characterized in that one contact terminal of the screw-free terminal block and one contact terminal of the socket contact are formed at respective ends of the same contact member, the other contact terminal of the screw-free terminal block is formed at one end of a plate spring member, the plate spring member holds an electric wiring between the plate spring member and the one contact terminal, the other end of the plate spring member extends toward the socket contact side, and a spring pressure is applied to the other contact terminal of the socket contact from outside.
According to the above configuration, the plate spring member required for the screw-free terminal block can be effectively used even on the socket contact side to apply the contact pressure between the contact terminals, and a connector-type screw-free terminal block having a socket contact with high contact reliability can be obtained without increasing the number of parts.
In the connector-type screw-free terminal block, the plate spring member may have a conductive structure.
According to the above configuration, since the electrical conduction between the socket contact and the screw-less terminal block can be obtained even by the plate spring member, the electrical characteristics of the connector-type screw-less terminal block are improved.
In the connector-type screw-free terminal block, the contact member may be made of an elastic copper material, and the plate spring member may be made of SUS.
According to the above configuration, good conductivity can be obtained by the contact member made of the elastic copper material, and the contact pressure between the contact terminals can be increased by the plate spring member made of SUS.
Further, in the above connector-type screw-less terminal block, the operation movable member is movable by a user receiving a predetermined operation when the socket contact is connected to the pin contact, the socket contact has two contact terminals that sandwich the pin contact when connected to the pin contact, the other contact terminal of the two contact terminals is urged in a direction of being pressed against the one contact terminal by the plate spring member, the other contact terminal is connected to the operation movable member, and the operation movable member moves in conjunction with the operation movable member when receiving the predetermined operation, so that a contact pressure between the terminals of the two contact terminals can be reduced.
According to the above configuration, when the socket contact and the pin contact of the connector-type screw-free terminal block are connected, the user operates the operation movable member, whereby the contact pressure between the terminals of the two contact terminals that sandwich the pin contact can be reduced. Thus, the socket contact and the pin contact can be connected with each other while the insertion force is eliminated or greatly reduced. Further, by releasing the operation of the movable member after the socket contact and the pin contact are joined, the pin contact is held between the two contact terminals with a high contact pressure, and high contact reliability can be ensured.

Detailed Description
Next, an embodiment of one side of the present disclosure will be described with reference to the drawings. Fig. 1 is a perspective view of a connector 10 of the present embodiment. Fig. 2 is a sectional view of the connector 10 at a fitting position between the pin contact 102 and the socket contact 210. In fig. 1, the connector 10 is exemplified as a four-pole multipolar connector, but the number of poles of the connector is not particularly limited. In addition, the connector 10 may be a single-pole connector.
The connector 10 is composed of a plug fitting 100 and a socket fitting 200. The socket fitting 200 is an example of the "connector-type screw-free terminal block" of the present invention. The plug accessory 100 includes a plug housing 101 and a pin contact 102, and is provided on, for example, a circuit board not shown. In the plug accessory 100, the pin contact 102 is accommodated in a space 101a formed in the plug housing 101, and one end (a connection side with the socket contact 210) of the pin contact 102 is exposed in the space 101 a. The space 101a is open at least at the insertion side of the socket fitting 200.
The socket fitting 200 has socket contacts 210 at one end and a screwless terminal block 220 at the other end.
Further, the structure of the socket fitting 200 is explained in more detail. The socket fitting 200 is substantially composed of a socket main body 201 and a lock lever 230. The lock lever 230 is attached to the socket body 201 so as to be rotatable about a fulcrum 201a (see fig. 1) provided in the socket body 201. The lock lever 230 is an example of the "operation 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 plate spring member 205. That is, the socket main body 201 accommodates the contact member 204 and the plate spring member 205 in a housing formed by the socket housing 202 and the cover housing 203.
The contact member 204 is made of a conductive material such as metal, and has one end serving as a first contact terminal 204a of the socket contact 210 and the other end serving as a third contact terminal 204b of the screw-free terminal block 220. It is preferable to use copper material for the spring (e.g., phosphor bronze) having elasticity and high electrical conductivity for the contact member 204. The plate spring member 205 is made of a material having a high elasticity (e.g., SUS), and has one end serving as the second contact terminal 205a of the socket contact 210 and the other end serving as the fourth contact terminal 205c of the screwless terminal block 220. Further, a hook 205b is formed at the tip of the second contact terminal 205a of the plate spring member 205.
The receptacle contact 210 of the receptacle metal fitting 200 is configured by disposing the first contact terminal 204a of the contact member 204 and the second contact terminal 205a of the plate spring member 205 so as to face each other. That is, the socket fitting 200 is fitted to the plug fitting 100, and the pin contact 102 is sandwiched between the first contact terminal 204a and the second contact terminal 205a of the socket contact 210, whereby the connector 10 is connected. In the socket contact 210, the second contact terminal 205a is pressed against the first contact terminal 204a by the elastic force of the plate spring member 205. The first contact terminal 204a may be a plate spring biased to press-contact the second contact terminal 205 a.
The screw-free terminal block 220 of the socket metal fitting 200 is configured by disposing the third contact terminal 204b of the contact member 204 and the fourth contact terminal 205c of the plate spring member 205 so as to face each other. The fourth contact terminal 205c is pressed against the third contact terminal 204b by the elastic force of the plate spring member 205. The receptacle housing 202 is provided with a wire insertion hole 202a and a wire releasing auxiliary hole 202 b. The wiring insertion hole 202a is a hole into which wiring (a stripped wire and a bar terminal) connected to the screw-free terminal block 220 is inserted, and the wiring inserted from the wiring insertion hole 202a is sandwiched between the third contact terminal 204b and the fourth contact terminal 205 c. The auxiliary wire connection releasing hole 202b is a hole for inserting a tool such as a screwdriver or the like to separate the fourth contact terminal 205c from the third contact terminal 204b when releasing the wire connection.
In the above description, the case where the plate spring member 205 is made of SUS is exemplified, and since the electrical conduction between the socket contact 210 and the screw-less terminal block 220 can be obtained by the contact member 204, the plate spring member 205 may not have the electrical conductivity. However, when the plate spring member 205 has conductivity, the electric conduction between the socket contact 210 and the screw-less terminal block 220 can be obtained not only by the contact member 204 but also by the plate spring member 205, and therefore, the electric characteristics of the socket fitting 200 are improved, which is preferable.
The lock lever 230 is rotatably attached to the socket body 201 around the support shaft 201a by engaging a support shaft 201a (see fig. 1) provided on a side surface of the socket body 201 with an engagement groove 231 (see fig. 1). One end (upper end in fig. 2) of the lock lever 230 is an operation portion 232 for a user to apply a force. An engagement protrusion 233 is formed at the other end (lower end in fig. 2) of the lock lever 230, and the engagement protrusion 233 is engaged with and connected to the hook 205b of the plate spring member 205. Therefore, the lock lever 230 is urged in the arrow a1 direction shown in fig. 2 by the elastic force of the plate spring member 205.
Next, referring to fig. 3(a) to 3(c), a fitting operation when the socket fitting 200 is inserted into the plug fitting 100 and fitted thereto will be described. Fig. 3(a) shows a state in which the socket accessory 200 and the plug accessory 100 are separated before fitting.
Fig. 3(b) shows a state during the fitting operation, in which the user holds the socket fitting 200 while holding the socket body 201 and the operation portion 232 of the lock lever 230. At this time, the lock lever 230 is rotated in the arrow a2 direction by the force acting on the operation portion 232. By rotating the lock lever 230 in the arrow a2 direction, the hook portion 205b of the plate spring member 205 is pulled by the engaging protrusion 233, and the first contact terminal 204a of the contact member 204 and the second contact terminal 205a of the plate spring member 205 are separated from each other. Then, by inserting the socket fitting 200 into the plug fitting 100 in a state where the first contact terminal 204a and the second contact terminal 205a are separated from each other, the frictional force generated between the pin contact 102 and the first contact terminal 204a and the second contact terminal 205a can be eliminated (or greatly reduced). That is, the socket fitting 200 can be inserted into the plug fitting 100 with an extremely small insertion force.
After the socket accessory 200 is inserted into the plug accessory 100, the user releases his hand, whereby the lock lever 230 is rotated in the arrow a1 direction due to the elastic force of the plate spring member 205, as shown in fig. 3 (c). Thereby, the pin contact 102 is held between the first contact terminal 204a and the second contact terminal 205 a. At this time, in addition to the elastic force of the plate spring member 205, the elastic force of the contact member 204 is combined, and a sufficient contact pressure is generated between the pin contact 102 and the contact member 204, so that an appropriate electrical connection between the pin contact 102 and the contact member 204 can be obtained. Further, the pin contact 102 can be appropriately held between the first contact terminal 204a and the second contact terminal 205 a. When the receptacle fitting 200 is pulled out from the plug fitting 100, the reverse operation may be performed to that performed when the plug fitting is inserted.
The lock lever 230 is preferably set so that the distance from the support shaft 201a to the end of the operation portion 232 is longer than the distance from the support shaft 201a to the end of the engagement protrusion 233. In this case, the principle of a lever can be used to increase the pressing force against the pin contact 102 while improving operability by reducing the operating force of the operating portion 232.
As described above, in the socket attachment 200 of the present embodiment, the fourth contact terminal 205c having the plate spring function is formed on the screw-free terminal block 220 at one end portion of the plate spring member 205, and the other end portion of the plate spring member 205 is extended toward the socket contact 210 side, and the second contact terminal 205a of the socket contact 210 is formed at the other end portion. Thus, the plate spring member 205 required for the screw-free terminal block 220 can be effectively used to apply the contact pressure between the contact terminals even on the socket contact 210 side, and the connector 10 having the socket contact 210 capable of obtaining high contact reliability can be obtained without increasing the number of parts. That is, the plate spring member 205 having high elasticity can easily increase the contact pressure between the contact terminals, and high contact reliability can be secured in the socket contact 210.
When the contact pressure between the contact terminals of the receptacle contact is generally increased, the receptacle contact and the pin contact are firmly fitted to each other, and it is difficult to insert and remove the connector. In contrast, in the connector 10 of the present embodiment, when the receptacle contact 210 and the pin contact 102 are inserted into and removed from each other, the contact pressure between the contact terminals can be reduced by operating the lock lever 230, and the insertion and removal of the connector 10 can be facilitated.
Further, the lock lever 230 and the plug fitting 100 may be provided with a holding mechanism for preventing the socket fitting 200 from coming off in a state where the socket fitting 200 is fitted to the plug fitting 100. Fig. 4 is a sectional view showing one configuration example of the holding mechanism. The cross section shown in fig. 4 is a cross section at a position different from that in fig. 2 and 3, and corresponds to a position where the first engagement portion 103 (see fig. 1) formed in the plug housing 101 is formed.
As shown in fig. 4, a first engaging portion 103 is formed on the surface of the plug housing 101 facing the lock lever 230. On the other hand, a second engaging portion 234 is formed on the other end portion (the same end portion as the engaging projection 233) of the latch lever 230 with respect to the support shaft 201a, on the surface facing the plug housing 101. In a state where the socket accessory 200 is fitted to the plug accessory 100 and the user releases his/her hand (a state corresponding to fig. 3 (c)), the first engaging portion 103 engages with the second engaging portion 234, whereby the socket accessory 200 can be prevented from coming off. When the socket accessory 200 is pulled out from the plug accessory 100, the engagement between the first engagement portion 103 and the second engagement portion 234 can be easily released by the operation of the lock lever 230.
In the above description, the connector 10 is composed of the socket fitting 200 and the plug fitting 100, and the plug fitting 100 is configured to house the pin contacts 102 in the plug housing 101. However, the use of the socket fitting 200 is not limited to the fitting with the plug fitting 100 described above, and the socket contact 210 may be used by fitting only the pin contact 102.
Fig. 5 shows a modification of the connector 10 of the present disclosure. In the connector 10 shown in fig. 5, a first contact terminal 204a and a second contact terminal 204c are formed on the same contact member 204 on the receptacle contact 210 side. The other end portion of the plate spring member 205 is configured to apply a 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, and a sufficient contact pressure can be obtained by applying the spring pressure from the plate spring member 205. In the configuration shown in fig. 5, when the lock lever 230 is operated to separate the other end portion of the plate spring member 205 from the second contact terminal 204c, the spring pressure applied by the plate spring member 205 is released and only the contact pressure of the contact member 204 exists, so that the contact pressure between the contact terminals on the receptacle contact 210 side can be reduced. This makes it possible to obtain the connector 10 in which the pin contacts 102 and the socket contacts 210 can be easily inserted and removed. In the configuration shown in fig. 5, the first contact terminal 204a and the second contact terminal 204c that are in direct contact with the pin contact 102 can both be made of copper for a spring having high electrical conductivity, and higher contact reliability can be obtained in the socket contact 210.
The embodiments disclosed herein are illustrative in all respects and not restrictive. Therefore, the technical scope of the present disclosure is not defined only by the above-described embodiments but by the description of the technical scope. The scope of the invention is intended to include all modifications within the meaning and range equivalent to the scope of the claims.
