Description

Technical Field

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

[0002] The main components of existing electrical connectors include a housing, terminals, a circuit board, and an injection-molded part covering the surface of the terminals. One end of the terminal is soldered to the circuit board to form a connection structure, through which signals are transmitted. The housing covers the outside of the injection-molded part to form a protective structure.

[0003] However, the existing injection molded parts and housings do not cover the surface of the circuit board and the connection between the terminals and the circuit board, which makes the circuit board prone to breakage or loosening at the connection between the circuit board and the terminals during use, affecting the normal use of the electrical connector. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for an anti-breakage electrical connector. By extending the tail of the housing to cover the reinforcing block on the circuit board, the overall bending strength of the electrical connector is improved, thus preventing breakage.

[0005] The technical solution adopted by the anti-breakage electrical connector structure disclosed in this utility model is: A breakage-resistant electrical connector structure includes a housing, a terminal group, and a circuit board. The tail of the terminal group is welded and fixed to one end of the circuit board. The surface of the terminal group is covered with an injection-molded part. The housing is sleeved on the outside of the injection-molded part. The surface of the circuit board is provided with a plurality of electronic components. A reinforcing block is wrapped at the connection between the circuit board and the terminal group. The reinforcing block covers the surface of the electronic components. The tail of the housing extends to cover the surface of the reinforcing block to form a reinforcing cover.

[0006] As a preferred embodiment, the electronic components are respectively disposed on the upper and lower surfaces of the circuit board, and the reinforcing block is respectively covered on the upper and lower surfaces of the circuit board.

[0007] As a preferred embodiment, the circuit board has a convex-shaped structure, and the reinforcing cover has slots on both sides, into which the two sides of the circuit board are inserted.

[0008] As a preferred embodiment, the terminal group includes a plurality of harpoon-shaped contact terminals and hooks. The hooks include a support arm and two clamping arms. The two clamping arms are disposed opposite to each other on both sides of the support arm, and a locking block is provided on the inner side of the clamping arm away from the circuit board. The contact terminals are disposed between the two clamping arms. A plurality of contact terminals are arranged at intervals along the support arm, and the tail of the contact terminals is soldered and fixed to the circuit board.

[0009] As a preferred embodiment, the clamping arm has a lug at one end near the circuit board, and the protruding part of the circuit board is inserted between the lugs of the two clamping arms to form a limiting structure.

[0010] As a preferred embodiment, the shell and the reinforcing cover are integrally formed, and the reinforcing block and the shell form a stepped structure.

[0011] The beneficial effects of the anti-breakage electrical connector structure disclosed in this utility model are as follows: by adding a reinforcing block at the welding point between the terminal group and the circuit board, the welding point is wrapped to increase its thickness, and the reinforcing block extends further to cover the electronic components on the circuit board, thereby improving the connection strength between the electronic components and the circuit board. At the same time, the force exerted on the circuit board when it is bent is dispersed and offset by increasing the overall thickness, thus preventing breakage when bent. Furthermore, by extending the shell, the strength of the reinforcing block is further strengthened, preventing breakage between the reinforcing block and the injection molded part.

[0016] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figures 1 to 4 A breakage-resistant electrical connector structure includes a housing 10, a terminal group 20, and a circuit board 30. The tail of the terminal group 20 is welded and fixed to one end of the circuit board 30. The surface of the terminal group 20 is covered with an injection molded part 40. The housing 10 is sleeved on the outside of the injection molded part 40. The surface of the circuit board 30 is provided with a plurality of electronic components. A reinforcing block 50 is wrapped at the connection between the circuit board 30 and the terminal group 20. The reinforcing block 50 covers the surface of the electronic components. The tail of the housing 10 extends to cover the surface of the reinforcing block 50 to form a reinforcing cover 11.

[0017] By adding a reinforcing block 50 to the solder joint between the terminal group 20 and the circuit board 30, the solder joint is wrapped, increasing its thickness. The reinforcing block 50 further extends to cover the electronic components on the circuit board 30, thereby improving the connection strength between the electronic components and the circuit board 30. Simultaneously, the force exerted on the circuit board 30 when bent is dispersed and offset by increasing the overall thickness, preventing breakage during bending. Furthermore, by extending the housing 10, the strength of the reinforcing block 50 is further enhanced, preventing breakage between the reinforcing block 50 and the injection molded part 40. In the above scheme, the electronic components are respectively set on the upper and lower surfaces of the circuit board 30, and the reinforcing block 50 is respectively covered on the upper and lower surfaces of the circuit board 30. This avoids the electronic components from being concentrated on one side of the circuit board 30, which would cause the operating temperature to be too high. Therefore, they are dispersed on the upper and lower surfaces to achieve better heat dissipation. At the same time, the reinforcing block 50 is used to reinforce and wrap the upper and lower surfaces of the circuit board 30.

[0018] The circuit board 30 has a convex-shaped structure. The reinforcing cover 11 has slots 12 on both sides. The two sides of the circuit board 30 are inserted into the slots 12, which can limit the circuit board 30. When the circuit board 30 is subjected to external force, some of the force can be distributed to the reinforcing cover 11, which can better relieve the force at the solder joint between the circuit board 30 and the terminal group 20.

[0019] Terminal group 20 includes several harpoon-shaped contact terminals 21 and hooks 22. Hooks 22 include support arms 221 and two clamping arms 222. The two clamping arms 222 are arranged opposite to each other on both sides of the support arm 221. A locking block 223 is provided on the inner side of the clamping arm 222 away from the circuit board 30. The contact terminals 21 are arranged between the two clamping arms 222. Several contact terminals 21 are arranged at intervals along the support arm 221, and the tail of the contact terminals 21 is soldered and fixed to the circuit board 30.

[0020] The latch 223 causes the hook 22 to form a clamping position when the electrical connector is inserted into the connector seat, thereby achieving a fixing effect.

[0021] The clamping arm 222 has a lug 224 near the end of the circuit board 30. The protruding part of the circuit board 30 is engaged between the lugs 224 of the two clamping arms 222 to form a limiting structure. The circuit board 30 limits the position of the hook 22 to prevent the hook 22 from shifting, thereby also limiting the position of the contact terminal 21.

[0022] The housing 10 and the reinforcing cover 11 are integrally formed, which facilitates processing and production, and also ensures the overall strength of the housing 10 and the reinforcing cover 11 to avoid breakage. The reinforcing block and the housing 10 form a stepped structure, which limits the insertion depth of the electrical connector when it is inserted. The housing 10 is inserted into the connector, while the reinforcing cover 11 remains outside to form a restriction.

[0023] This utility model provides a structure for an anti-breakage electrical connector. By adding a reinforcing block at the welding point between the terminal group and the circuit board, the welding point is wrapped to increase its thickness. The reinforcing block extends further to cover the electronic components on the circuit board, thereby improving the connection strength between the electronic components and the circuit board. At the same time, the force exerted on the circuit board when it is bent is dispersed and offset by increasing the overall thickness, preventing breakage when bent. Furthermore, by extending the shell, the strength of the reinforcing block is further enhanced, preventing breakage between the reinforcing block and the injection molded part.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
