Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a lengthened anti-break connector structure. Background Art

[0002] The existing connector structure mainly consists of a circuit board, terminals, an insulator and a shell. The terminal is fixed to one end of the circuit board by welding, the insulator is injection molded to the outside of the terminal, and the shell is wrapped around the outside of the insulator to form a complete connector.

[0017] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:

[0018] Please refer to Figure 1 、 Figure 2 and Figure 3, an extended anti-break connector structure, including a shell 10, an insulator 20, a terminal group 30 and a circuit board 40, one end of the terminal group 30 is embedded in the insulator 20, and the other end extends out of the insulator 20, the circuit board 40 is arranged at one end of the insulator 20, and the circuit board 40 is welded and fixed to the terminal group 30, the shell 10 includes a wrapping portion 11 and a limiting portion 12, the limiting portion 12 is arranged at one end of the wrapping portion 11, and the limiting portion 12 and the wrapping portion 11 form a stepped structure, the limiting portion 12 is provided with an extension arm 13 at the end away from the wrapping portion 11, the extension arm 13 is located on both sides of the limiting portion 12, the extension arm 13 is opened with a notch 131, the circuit board 40 is embedded in the notch 131, and the circuit board 40 is welded and fixed to the extension arm 13 corresponding to the notch 131.

[0019] The terminal group 30 is embedded in the insulator 20 to improve the firmness of the terminal group 30, while also serving the purpose of insulation and isolation. The terminal group 30 is welded to the circuit board 40, and can be connected to external wires or other equipment through the circuit board 40. The wrapping portion 11 of the shell 10 is wrapped around the outside of the insulator 20 to serve the purpose of electromagnetic shielding, while also improving the overall strength. The limiting portion 12 is used to determine the depth of the wrapping portion 11 inserted into the female seat when the connector is inserted. An extension arm 13 is provided at one end of the limiting portion 12 away from the wrapping portion 11. The extension arm 13 is used to further weld and fix the circuit board 40 to the shell 10, thereby increasing the force points of the circuit board 40, improving its bending resistance, and avoiding the loosening of the circuit board 40 and the terminal group 30 or the breakage of the circuit board 40.

[0020] In the above solution, the terminal assembly 30 includes several contact terminals 31 and hooks 32. The hooks 32 are U-shaped. Several contact terminals 31 are arranged in intervals within the insulator 20. The hooks 32 are arranged horizontally at the tail ends of the contact terminals 31, and the two ends of the hooks 32 are located outside the contact terminals 31. The horizontal arrangement of the hooks 32 can restrain the contact terminals 31, and the two ends of the hooks 32 can cooperate with the tongue plate in the female socket when the connector is inserted, achieving a better fixation effect.

[0021] The insulator 20 has slots 21 at both ends of the hook 32, corresponding to the ends of the hook 32. The ends of the hook 32 protrude through the slots 21 to contact the housing 10. The hook 32 is welded to the housing 10, and there are only two weld points 14, which are arranged along the extension direction of the housing 10. The slots 21 connect the hook 32 to the housing 10, thereby achieving grounding. The hook 32 is also welded to the housing 10 by laser welding, ensuring good contact and fixation between the hook 32 and the housing 10, and improving the secure fit of the housing 10 on the exterior of the insulator 20.

[0022] The circuit board 40 includes a stop portion 41, a soldering portion 42 and a connecting portion 43. The stop portion 41, the soldering portion 42 and the connecting portion 43 form a three-section structure in sequence, and the stop portion 41, the soldering portion 42 and the connecting portion 43 gradually widen in the direction away from the terminal group 30. The connecting portion 43 is close to the side of the soldering portion 42 and is embedded in the notch 131. The stop portion 41 is stuck in the tail of the contact terminal 31 and the insulator 20. The soldering portion 42 extends out of the insulator 20 and is arranged between the two extension arms 13. The terminal group 30 is welded and fixed to the soldering portion 42, and the connecting portion 43 extends out of the housing 10.

[0023] The circuit board 40 is set in the insulator 20 through the stop part 41, and the terminal group 30 and the stop part 41 are wrapped and fixed by the insulating member, and the welding part 42 is used for welding and fixing the terminal group 30, avoiding the traditional direct welding on the edge of the circuit board 40, which causes the circuit board 40 to fall off when subjected to force, thereby improving the force strength of one end of the circuit board 40, and the welding part 42 is located between the two extension arms 13, which is convenient for people to check whether the terminal group 30 and the welding part 42 are welded in place, and serves the purpose of inspection, and the connecting part 43 extends out of the shell 10 for connection to external equipment.

[0024] The two extension arms 13 are inclined on one side close to each other and are inclined inward toward the center of the shell, which improves the connection strength between the extension arm 13 and the limiting portion 12. When the extension arm 13 is subjected to external force, the force can be better dispersed and act on the middle of the limiting portion 12 along the oblique edge.

[0025] The utility model provides an extended anti-break connector structure, which embeds the terminal group into the insulator to improve the firmness of the terminal group, and at the same time can also achieve the purpose of insulation isolation, and the terminal group is welded to the circuit board, which can be connected to external wires or other equipment through the circuit board. The wrapping part of the shell is wrapped around the outside of the insulator to achieve the purpose of electromagnetic shielding, and also improves the overall strength. The limiting part is used to determine the depth of the wrapping part inserted into the female seat when the connector is inserted in use. An extension arm is provided at one end of the limiting part away from the wrapping part, and the circuit board is further welded and fixed to the shell by using the extension arm, thereby increasing the force points of the circuit board, improving its anti-bending performance, and avoiding the situation where the circuit board and the terminal group become loose or the circuit board breaks.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
