Connector snap linkage device

The present invention relates to a connector, in particular to a connector snap linkage device with better electrical connection and release functions.

Many consumer electronics products today, such as computer technology, are changing with each passing day. The development trend is also moving towards strong computing power, high speed and small size. As a result, the number of computer communication ports is also reduced. Such communication ports may also be Using plugs of the same specifications on other devices allows the electrical connector to be positioned on the mating connector and electrically connected to it to transmit signals. In addition to sockets, the communication ports in these devices are wire plugs or wire connectors that combine cables with plugs. This type of wire plug/wire connector usually pulls the wire directly during the plugging and unplugging process. , when the wire plug/cable connector does not have any support or fixed structure, or when it is subjected to an external force in an up-down direction after being docked with the butt female connector, because the butt female connector is not affected by the wire connector Therefore, it is easy for the wire connector to fall off due to shaking or collision after being inserted into the female connector, thus affecting the signal transmission.

In order to effectively solve the above problems, one object of the present invention is to connect the second linkage member with the first linkage member and the housing through a structural relationship, and use the hook portion to protrude upward from the top wall to engage with the docking female base. buckle, or when the second linking member is pulled, the first linking member presses down the driven part and moves downward, causing the hook part to elastically move downward a distance to release the buckle separation effect. Provides a snap linkage device with a simple structure, easy operation, stable snap and high reliability of the connector. Another object of the present invention is to provide a connector snap linkage device that is easy to operate, firmly positioned, not easy to fall off and shake, and has a reliable electrical contact function.

The holding groove 32 , the coupling groove 153 of the housing 10 and the receiving groove 161 are connected to the holding portion 42 . In specific implementation, with the above structure and referring to Figures 4A, 4B and 5, the main body part 21 and the extension part 22 of the buckle 2 are respectively disposed in the assembly grooves of the assembly part 15 of the housing 10. 151 and the slot 152, the hook portion 221 protrudes upwards out of the slot 152 and is higher than the top wall 11, and the elastic portion 23 and the passive portion 24 are accommodated in the accommodation groove 161 of the mounting portion 16 , the second section 233 is against the limiting groove 163 located on the recessed surface 162, thereby causing the elastic portion 23 to have a downward elastic force and causing the hook portion 221 of the buckle 2 to protrude upward ( That is, higher than the top wall 11 of the housing 10 . The first linkage 3 slides into the horizontal guide rails 164 on both sides of the accommodating groove 161 through the two sliders 33 to be disposed in the accommodating groove 161 of the mounting part 16 of the housing 10, and It is located above the elastic part 23 and the driven part 24, so that the first pressing position (ie, the pressing slope) 311 of the pressing part 31 corresponds to and is located above the first section 232 of the elastic part 23, so that the first section 232 forms a receiving part. The pressure surface (not numbered), the second pressing position 312 is located above the driven part 24 and corresponds to the pressure-receiving section 241, the penetration groove 32 is communicated with the accommodating groove 161, and the first linkage member 3 The bottom corresponds to the second sections 233 that are limited in the limiting groove 163 , and the gap 34 corresponds to between the two second sections 232 of the two elastic parts 23 of the buckle 2 , so that The top surface of the first linking member 3 protrudes from the mounting portion 16 . The second connecting member 4 passes between the gap 34 of the first connecting member 3 and the two elastic portions 23 from the outside, then passes through the coupling groove 153 of the housing 10 from the bottom, and passes from above and turns around. After the main body portion 21 of the buckle 2 penetrates the penetration groove 32 of the first connector 3, it then turns and penetrates the combination groove 153 of the housing 10 and passes out from below, entering the receiving recess of the mounting portion 16. The connecting part 41 is formed in the groove 161 and is connected with the holding part 42, so that the holding part 42 of the second connecting member 4 is close to the recessed surface 162 and extends appropriately in the direction of the wire 6 (as shown in Figure 5 Show). Therefore, through the structural design of the snap linkage device of the connector of the present invention, as shown in Figures 1, 2, 5, 6A, 6B, and 7, through the connection between the second linkage member 4 and the first linkage member 3 The penetration groove 32 is connected to the coupling groove 153 of the housing 10 of the connector 1. The first linking member 3 is coupled to the mounting portion 16 of the connector 1, so that the buckle 2 is connected to the limiter through the second section 233. The positioning slot 163 is positioned between the mounting portion 16 and the linkage assembly. When the connector 1 uses the first end 13 of the housing 10 (i.e., the docking port) for the front end of the mating female base T to be inserted into the connector, the mating female base T can correspond to and slide into the side walls 12 using the guide blocks t2 on the outer walls. The horizontal track 121 allows the front end of the docking female base T to be accurately received in the receiving space P and electrically connected to the circuit board 5, and the upwardly protruding hook portion 221 at the free end of the extension 22 is accurately The elastic buckle is in the buckle hole t1 on the top surface of the docking female base T to achieve the purpose of buckling. When the second linking part 4 is pulled in the direction of the wires 6 with the holding part 42 (which is close to the recessed surface 162 ), the connecting part 41 can link the first linking part 3 . At this time, the first linking part 3 is pressed The surface protrudes from the top wall 11 of the housing 10 (positioned at a high level) and the holding portion 42 is close to the recessed surface 162 (positioned at a low level), so that the connecting portion 41 pulls the first linkage backward. When the front side of the component 3 moves forward, the pressing part 31 presses down the first section 232 (the pressure-receiving surface) of the elastic part 23 at the first pressing position (ie, the pressing slope) 311 and the second pressing position 312 respectively. The pressure section 241 of the driven part 24 moves downward (the movement is relative to the pressing space), so the main part 21, the extension part 22 and the hook part 221 are linked to move upward in the assembly groove 151 and the slot 152. The lower elasticity is offset by a distance to achieve the purpose of unlocking. That is to say, this unlocking solution can ensure that the pressing part 31 of the first linking member 3 accurately pushes the driven part 24 downward to drive the elastic member 23 to move downward, thereby linking the hooking of the extending part 22 The portion 221 elastically deflects downward by a certain distance and accurately separates from the mating female seat T to achieve the unlocking state. Therefore, the reliability of buckling and unlocking can be improved, and the effect of convenient buckling electrical connection can be achieved, and a buckling linkage device of the connector is provided that is easy to operate, firmly positioned, not easy to fall off and shake, and has a reliable electrical contact function. The present invention has been described in detail above. However, the above description is only one of the preferred embodiments of the present invention and cannot limit the scope of the present invention. That is to say, all equivalent changes and modifications made according to the application scope of the present invention should still fall within the scope of the patent of the present invention.
