Electrical connector snap-fit ​​structure

Abstract

This utility model relates to an electrical connector fastening structure, which includes a socket connector and a plug connector. The socket connector has an internal insertion space and a supporting surface on one side of the body. Several positioning protrusions extending into the insertion space are raised on the supporting surface. A side wall extends from each side of the supporting surface, and a stop portion is raised at the top of each side wall. The plug connector is vertically disposed inside the insertion space of the socket connector from top to bottom. Several fastening grooves are recessed on the front head of the plug connector to engage and position with the positioning protrusions. A protrusion is raised on each side of the plug connector and positioned below the stop portion. The fastening grooves of the plug connector engage with the positioning protrusions of the socket connector from top to bottom for positioning. At the same time, the protrusions of the plug connector are deformed to abut against the bottom of the stop portion to prevent the plug connector from disengaging upwards or backwards.

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector snap-fit ​​structure. Background Technology

[0002] The rapid development of electronic technology and the Internet has led to the continuous emergence of various electronic products, which are gradually becoming lighter, thinner, shorter, smaller, easier to carry, and faster in terms of computing and transmission speed. Among them, the electrical connectors used in electronic devices such as computer mainframes and laptops are also becoming smaller in size. Therefore, the design of positioning electrical connectors to accommodate the reduction in size is a key area that those engaged in this industry urgently need to study and improve.

[0003] The prior art, disclosed in the patent announcement number CN202510781397.0, is a rectangular connector with a combined quick-lock structure. Due to the problem of the usage environment, the prior art cannot show that moving backward or upward will cause the connector to lose its mating function.

[0004] Therefore, it is necessary to design an electrical connector snap-fit ​​structure to solve the above problems. Utility Model Content

Detailed Implementation

[0017] Reference Figures 1 to 4 An electrical connector fastening structure includes a socket connector and a plug connector, and the connection relationship of the aforementioned components is as follows; The body 11 of the socket connector 1 has an insertion space 10 inside, and the body 11 has a supporting surface 111 at the bottom of the insertion space 10. A plurality of positioning protrusions 1111 extending into the insertion space 10 are provided on the supporting surface 111. Side walls 112 extend from both sides of the supporting surface 111, and each side wall 112 has a first limiting portion 1121 extending into the insertion space 10 protruding near the supporting surface 111. A limiting groove 1120 is formed between the first limiting portion 1121 and the supporting surface 111. Furthermore, a limiting groove 1120 is formed between each side wall. 112 is provided with a second limiting part 1122 extending into the insertion space 10 at a distance away from the abutting surface 111, and a stop part 1123 is provided at the top between the first limiting part 1121 and the second limiting part 1122. A stop groove 1124 is formed at the bottom of the stop part 1123. The body 11 is for assembling a plurality of conductive terminals 12, and each conductive terminal 12 has a mating part 121 extending from the abutting surface 111 toward the insertion space 10. A welding part 122 extending out of the body 11 is provided on the opposite side of the mating part 121.

[0018] The plug connector 2 is vertically disposed from top to bottom inside the insertion space 10 of the socket connector 1. The interior of the plug connector 2 has an accommodating space 20 for assembling a plurality of preset conductive terminals (not shown in the figure). The front end of the plug connector 2 has a head 21 corresponding to the abutment surface 111 of the body 11. A plurality of locking grooves 210 are recessed on the head 21 to engage and position with each of the positioning protrusions 1111. A plurality of slots 211 are cut on the head 21 at the mating portion 121 corresponding to each of the conductive terminals 12. 21 has a retaining flange 212 extending on both sides, which abuts against the surface of each of the sidewalls 112 and is fixed within the limiting groove 1120. Then, the plug connector 2 has a protrusion 22 at each of the two stop portions 1123 corresponding to the body 11, which is positioned below the stop portion 1123. The top surface of the protrusion 22 has a stop surface 221 that abuts against the bottom surface of the stop portion 1123. The plug connector 2 has a plurality of through holes 23 on the opposite side of the head 21 for a preset cable (not shown in the figure) to pass through and electrically connect with the preset conductive terminal inside.

[0019] In a preferred embodiment, the conductive terminals 12 are attached to the body 11 of the socket connector 1 by means of an injection molding process, and the preset conductive terminals are also attached to the plug connector 2 by means of an injection molding process.

[0020] In practical applications, the soldering portions 122 of the conductive terminals 12 extending from one side of the body 11 of the socket connector 1 are first soldered to a plurality of preset contacts (not shown in the figure) on a default circuit board (not shown in the figure). Then, the plug connector 2 is vertically positioned from top to bottom within the insertion space 10 of the socket connector 1, so that it engages with the positioning protrusions 1111 of the body 11 through the recessed grooves 210 on the head 21 of the plug connector 2. Simultaneously, the grooves 211 of the plug connector 2 allow the mating portions 121 of the conductive terminals 12 to pass through the accommodating space 20 and contact the preset conductive terminals to generate an electrical connection. The electronic signals are then transmitted through the soldering portions 122. When the connector is transferred to the default circuit board, the abutting flanges 212 on both sides of the head 21 abut against the surface of the sidewalls 112 on both sides of the body 11. The first limiting portions 1121 block and limit the connector from the rear of the abutting flanges 212 to prevent the plug connector 2 from exiting the socket connector 1. At the same time, the protrusions 22 on both sides of the plug connector 2 are deformed by the downward pressing force and are positioned below the stop portion 1123. After the stop surface 221 of the protrusion 22 is deformed and reset, it will abut against the bottom surface of the stop portion 1123 to prevent the plug connector 2 from exiting the socket connector 1. The second limiting portions 1122 block and limit the connector from the rear of the protrusions 22.

[0021] The advantages of this utility model are that the recessed grooves 210 on the head 21 of the plug connector 2 can be fastened and fixed on the positioning protrusions 1111 at the same time as the plug connector 2 is inserted into the socket connector 1 and an electrical connection is generated. In addition, the protrusions 22 on both sides of the plug connector 2 abut against the bottom of the stop portions 1123 to prevent the plug connector 2 from falling out of the insertion space 10 backward and upward, thereby being firmly fixed in the socket connector 1.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
