Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically to an anti-detachment connector. Background Technology

[0002] After the Type-C male connector is manufactured, it needs to undergo potting and injection molding on the connector housing to form a rubber sleeve (such as...) on the housing. Figure 1 (as shown), so as to connect the wires.

[0003] After molding, existing connectors and sleeves require a tensile test, which involves repeatedly pulling the connector and sleeve in opposite directions to check the strength of their molding. To pass the tensile test, the usual approach is to work on the injection molding process and the material of the sleeve. For example, using a higher pressure injection molding method can make the adhesive adhere tightly to the shell. However, this method can easily damage the connector itself. Alternatively, a higher density adhesive material can be used to mold the sleeve, but this will increase the procurement cost of the adhesive and reduce the company's profit margin. Utility Model Content

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 2 As shown, an anti-disengagement connector includes a housing 100 and an insulating body 200 enclosed by the housing 100. A terminal assembly 300 is installed inside the insulating body 200. A receiving cavity 210 is provided inside the insulating body 200. A connection port 211 is formed on one side of the receiving cavity 210 for inserting other connector females. A circuit board 400 is connected to the side of the terminal assembly 300 away from the connection port 211. The housing 100 includes a top wall 110 and a bottom wall 120, and two side walls 130 for connecting the top wall 110 and the bottom wall 120. A stop plate 140 is provided on the top wall 110 and the bottom wall 120, and the stop plate 140 is perpendicular to the top wall 110 and the bottom wall 120.

[0029] In this embodiment, during assembly, the terminal assembly 300 is first inserted into the insulating body 200 by plugging, and a part of the terminal assembly 300 extends into the receiving cavity 210, so as to facilitate the formation of an electrical connection when inserting other connector sockets. Then, the housing 100 is fixed to the outside of the insulating body 200. Finally, the housing 100 is molded and glued to the outside of the housing 100 to form a rubber sleeve 20 for connecting wires.

[0030] This application provides stop plates 140 on the top wall 110 and bottom wall 120, with the stop plates 140 perpendicular to the top wall 110 and bottom wall 120. When a rubber sleeve 20 is injection molded on the outside of the housing 100, and then a tensile test is performed on the housing 100 and the rubber sleeve 20, the stop plates 140 will generate resistance in a direction parallel to the top wall 110 and bottom wall 120, thereby further improving the tensile strength between the housing 100 and the rubber sleeve 20 and improving the durability of the final product.

[0031] Furthermore, based on this embodiment, such as Figure 3As shown, the stop plate 140 is integrally formed with the housing 100. An extension arm 131 extends from the side wall 130 of the housing 100 toward the circuit board 400. A potting area 150 is formed between the extension arm 131 and the circuit board 400. The stop plate 140 is disposed in the potting area 150. Since the thickness of the circuit board 400 is less than the thickness of the housing 100, when the mold is potted on the outside of the housing 100, the glue will completely penetrate into the potting area 150, thereby wrapping the entire stop plate 140. Thus, when the housing 100 and the rubber sleeve 20 are subjected to a tensile test, the resistance provided by the stop plate 140 is better.

[0032] Furthermore, based on this embodiment, such as Figure 4 As shown, a bent portion 141 is provided at the end of the stop plate 140 away from the housing 100. The bent portion 141 bends toward the side of the connection port 211. In this way, when the rubber sleeve 20 is formed, the rubber body and the stop plate 140 are actually connected in a hook-like manner, which can further improve the resistance effect of the stop plate 140.

[0033] Furthermore, based on this embodiment, such as Figure 4 As shown, a reinforcing groove 160 recessed toward the connection port 211 is provided on the housing 100 between the stop plate 140 and the extension arm 131. When the housing 100 and the rubber sleeve 20 are subjected to a tensile test, the reinforcing groove 160 can ensure that the tensile force is concentrated on the stop plate 140, thereby reducing the excessive tensile force on other parts of the housing 100 and thus protecting the housing 100.

[0034] In some embodiments, such as Figure 4 As shown, a strip-shaped first guide groove 131a is provided on the extension arm 131. The first guide groove 131a is parallel to the extension arm 131. Embedding blocks 410 are provided at both ends of the circuit board 400. When the circuit board 400 is connected to the terminal assembly 300, the embedding blocks 410 are inserted into the first guide groove 131a. This firstly guides the connection direction of the terminal assembly 300 and the circuit board 400 during assembly. Secondly, after potting, the embedding blocks 410 are inserted into the first guide groove 131a, thus strengthening the stability of the connection between the terminal assembly 300 and the circuit board 400.

[0035] Furthermore, based on this embodiment, such as Figure 5As shown, the insulating body 200 is provided with a plurality of slots 220 for inserting terminal assembly 300. The slots 220 communicate with the receiving cavity 210. The slots 220 are arranged along the vertical direction of the insulating body 200 and are parallel to each other. A support portion 221 is horizontally placed in the slot 220. The support portion 221 is used to support the terminal assembly 300 in the slot 220.

[0036] In some embodiments, combined with Figure 4 and Figure 5 As shown, a limiting block 230 is provided between the slots 220. The limiting block 230 is located at the end of the insulating body 200 away from the connection port 211. A second guide groove 420 is provided on the circuit board 400. When the circuit board 400 is connected to the terminal assembly 300, the limiting block 230 is engaged in the second guide groove 420. In this way, when the terminal assembly 300 and the circuit board 400 are assembled, the limiting block 230 plays an auxiliary guiding role in the connection direction of the terminal assembly 300 and the circuit board 400.

[0037] In some implementations, such as Figure 6 As shown, a partition plate 500 is also provided in the terminal assembly 300. The partition plate 500 includes two clamping arms 510 and a connecting arm 520 for connecting the clamping arms 510. Through grooves 240 are provided on the two side walls 130 of the insulating body 200. The through grooves 240 communicate with the receiving cavity 210. When the partition plate 500 needs to be installed, the terminal assembly 300 is first inserted into the slot 220. Then, the clamping arms 510 of the partition plate 500 are inserted along the through grooves 240 on the side walls 130 of the insulating body 200, so that the clamping arms 510 extend into the receiving cavity 210.

[0038] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
