[0027] Please refer to Figure 1-Figure 6 The embodiment of the utility model provides a multi-pin connector 100, including a socket assembly 110 and a plug assembly 120. The socket assembly 110 includes a socket body 111 and a plurality of first terminals 112. The socket body 111 forms a receiving cavity 1111. A stopper 1112 is protruded on one side of the receiving cavity 1111. Each first terminal 112 is plugged into the receiving cavity 1111 and suspended below the stopper 1112. The plug assembly 120 includes a plug body 121, a plurality of second terminals 122 and a locking member 121. 3. The plug body 121 is formed with a step portion 1211 aligned with the limit platform 1112. Each second terminal 122 is plugged into the plug body 121 and is located below the step portion 1211. The locking member 123 is clamped on the plug body 121 between the two step portions 1211. When the plug body 121 is inserted into the socket body 111, the first terminal 112 abuts against the second terminal 122, the limit platform 1112 abuts against the step portion 1211, and the locking member 123 is used to lock the plug body 121 and the socket body 111. In specific applications, since the socket body 111 forms an accommodating cavity 1111, a limit platform 1112 is protruded from one side of the accommodating cavity 1111, each first terminal 112 is inserted into the accommodating cavity 1111 and is suspended below the limit platform 1112, and the plug body 121 forms a step portion 1211, each second terminal 122 is inserted into the plug body 121 and is located below the step portion 1211, and the locking piece 123 is clamped on the plug body 121 between the two step portions 1211, so that when the plug body 121 is inserted into the socket body 111, the first terminal 112 abuts against the second terminal 122, the limit platform 1112 abuts against the step portion 1211, and the locking piece 123 is used to lock the plug body 121 and the socket body 111, thereby making it easier to pull out the connection between the plug body 121 and the socket body 111 through the limit platform 1112 and the step portion 1211, thereby avoiding the difficulty of pulling out the plug connector from a multi-pin miniaturized socket connector.

[0028] In a possible implementation, the limiting platform 1112 forms an abutting portion 11121, the abutting portion 11121 is located at one end of the limiting platform 1112 and is tilted upward, and the step portion 1211 is formed with a groove 12111, and when the plug body 121 is inserted into the socket body 111, the abutting portion 11121 is located in the groove 12111. In a specific application, in order to improve the smoothness of the socket connector and the plug connector, the limiting platform 1112 forms an abutting portion 11121, the abutting portion 11121 is located at one end of the limiting platform 1112 and is tilted upward, and the step portion 1211 is formed with a groove 12111, so that when the plug body 121 is inserted into the socket body 111, the abutting portion 11121 is located in the groove 12111, so that a gap is formed between the abutting portion 11121 and the groove 12111, so that the plug body 121 is easily pulled out of the socket body 111.

[0029] In a possible implementation, the socket body 111 is further formed with a buckle portion 1113, which is located at one side of the accommodating cavity 1111. When the plug body 121 is inserted into the socket body 111, the locking member 123 is buckled with the buckle portion 1113. In a specific application, since the socket body 111 is further formed with a buckle portion 1113, which is located at one side of the accommodating cavity 1111, when the plug body 121 is inserted into the socket body 111, the locking member 123 is buckled with one side of the buckle portion 1113, thereby improving the reliability of the connection between the socket body 111 and the plug body 121. It is worth noting that the buckle portion 1113 is buckled with the buckle portion 1113, thereby improving the reliability of the connection between the socket body 111 and the plug body 121. At the same time, the connection between the step portion 1211 and the limiting platform 1112 can improve the convenience of pulling out the plug body 121 from the socket body 111.

[0030] In a possible embodiment, the plug body 121 is also provided with a connecting portion 1212, and the connecting portion 1212 is formed with an avoidance groove 12121. The locking member 123 is inserted into the connecting portion 1212 and forms a locking groove 12321 with the avoidance groove 12121. The locking groove 12321 is connected to the bottom of the avoidance groove 12121, and the buckle portion 1113 abuts against the locking groove 12321 so that the locking member 123 locks the plug body 121 and the socket body 111. In specific applications, in order to enable the locking member 123 to lock the plug body 121 and the socket body 111, the plug body 121 is also provided with a connecting portion 1212, and the connecting portion 1212 is formed with an avoidance groove 12121. The locking member 123 is inserted into the connecting portion 1212 and forms a locking groove 12321 with the avoidance groove 12121. The locking groove 12321 is connected to the bottom of the avoidance groove 12121. When the plug body 121 is inserted into the socket body 111, the buckle portion 1113 abuts against the locking groove 12321, so that the plug body 121 and the locking member 123 are locked in the socket body 111 together.

[0031] In a possible embodiment, the connecting portion 1212 also forms a limiting groove 12122, which is located on one side of the avoidance groove 12121. The locking member 123 includes an elastic buckle portion 1231 and a locking tongue 1232. A locking groove 12321 is formed in the middle of the locking tongue 1232. The elastic buckle portion 1231 is buckled in the limiting groove 12122 to limit the displacement of the locking member 123 relative to the plug body 121. In specific applications, since the connecting portion 1212 also forms a limiting groove 12122, the limiting groove 12122 is located on one side of the avoidance groove 12121, and the locking member 123 includes an elastic buckle portion 1231 and a locking tongue 1232, and a locking groove 12321 is formed in the middle of the locking tongue 1232. The elastic buckle portion 1231 is buckled in the limiting groove 12122, so that the locking member 123 is locked in the plug body 121 by the limiting groove 12122 on the side of the connecting portion 1212, thereby preventing the locking member 123 from accidentally falling off relative to the plug body 121.

[0032] In a possible implementation, when the elastic buckle 1231 is separated from the limiting groove 12122, the locking groove 12321 formed by the locking member 123 and the avoiding groove 12121 is invalidated, so that the locking member 123 releases the locking of the buckle 1113. In a specific application, when the plug body 121 needs to be pulled out from the socket body 111, the elastic buckle 1231 needs to be separated from the limiting groove 12122, so that the locking groove 12321 formed by the locking member 123 and the avoiding groove 12121 is invalidated, and then the locking member 123 releases the locking of the buckle 1113, so that the plug body 121 can be quickly and conveniently pulled out from the socket body 111.

[0033] In a possible implementation, the connection portion 1212 is provided with an anti-skid groove 12123, and the anti-skid groove 12123 is arranged near one end of the locking member 123. In a specific application, since the connection portion 1212 is provided with an anti-skid groove 12123, and the anti-skid groove 12123 is arranged near one end of the locking member 123, it is convenient to manually operate the elastic buckle 1231 of the locking member 123 to fall off the limiting groove 12122.

[0034] In a possible implementation, support bars 11111 are evenly spaced and protruded from the side wall of the accommodating cavity 1111, and the plug body 121 abuts against one side of the support bar 11111. In a specific application, in order to improve the smoothness of plugging and unplugging the plug body 121 in the socket body 111, support bars 11111 are evenly spaced and protruded from the side wall of the accommodating cavity 1111, and the plug body 121 abuts against one side of the support bar 11111, thereby reducing the contact area between the plug body 121 and the socket body 111, thereby reducing the friction between the plug body 121 and the socket body 111 and improving the smoothness of plugging and unplugging.

[0035] In a possible implementation, a support platform 11112 is provided on one side of the accommodating cavity 1111, and the support platform 11112 is arranged opposite to the buckle portion 1113, and a support bar 11111 is formed on the surface of the support platform 11112. In a specific application, in order to avoid the force collapse between the plug body 121 and the socket body 111, a support platform 11112 is provided on one side of the accommodating cavity 1111, and the support platform 11112 is arranged opposite to the buckle portion 1113, and a support bar 11111 is formed on the surface of the support platform 11112, so that the support platform 11112 can support the position of the plug body 121 in the socket body 111.

[0036] In a possible implementation, the socket assembly 110 further includes a positioning member 113, and the socket body 111 further includes a slot 1114, and the positioning member 113 is engaged with the slot 1114, so that the socket body 111 is fixed to the substrate through the positioning member 113. In a specific application, since the socket assembly 110 further includes a positioning member 113, and the socket body 111 further includes a slot 1114, and the positioning member 113 is engaged with the slot 1114, the positioning member 113 is connected to the slot 1114, so that the multi-pin connector 100 is fixed to the substrate through the positioning member 113.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
