Description

Technical Field

[0002] In electronic devices with lighting connectors as external interfaces, external forces from plugging, unplugging, bending, and other operations will directly act on the connector body.

[0015] Figure 2 The utility model is an exploded view of a connector structure with an anti-dropping shell. DETAILED DESCRIPTION

[0016] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0017] Please refer to Figure 1 and Figure 2 A connector structure with an anti-falling shell 10 includes a shell 10, a PCB board 20 and an insulator 30. One end of the PCB board 20 is arranged in the shell 10, and the insulator 30 is filled in the shell 10. A fixing strip 21 is provided on the surface of the PCB board 20. The fixing strip 21 protrudes from the surface of the PCB board 20. The fixing strip 21 contacts one end of the shell 10, and the fixing strip 21 and the shell 10 are welded and fixed to form a solder joint, and the solder joint is located above the PCB board 20.

[0018] When assembling the connector, the PCB board 20 is inserted into the housing 10, and one end of the PCB board 20 extends out of the housing 10, and the fixing bar 21 on the PCB board 20 contacts one end of the housing 10. The fixing bar 21 and the housing 10 are first welded to fix the PCB board 20 and the housing 10. The welding condition of the fixing bar 21 and the housing 10 can be directly observed from the outside, thereby avoiding the occurrence of cold solder joints. Then, the insulator 30 is poured into the housing by injection molding to form an insulating partition, and the PCB board 20 and the housing 10 are further reinforced, thereby ensuring the strength of the connector while avoiding damage to the PCB board 20.

[0019] In the above scheme, a contact window 11 is provided at one end of the housing 10 away from the solder joint, and a terminal group 22 is provided on the PCB board 20 corresponding to the contact window 11, and the contact window 11 is provided on the upper surface and the lower surface of the housing 10 respectively, and the terminal group 22 is provided on the upper surface and the lower surface of the PCB board 20 correspondingly. The terminal group 22 can ensure that the connector has good connectivity when inserted and used, and at the same time, the upper surface and the lower surface of the housing 10 are provided with the terminal group 22, so that the front and back sides are the same and can be inserted and connected. The surface of the PCB board 20 extending out of the housing 10 is provided with an electronic component 23.

[0020] The two sides of the shell 10 near one end of the welding point are stepped, and a slot 31 is opened at the edge of the insulator 30 corresponding to the shell 10. One end of the shell 10 is embedded in the slot 31, thereby increasing the contact area between the shell 10 and the insulator 30. The stepped structure can effectively form a dislocation, so that the shell 10 and the insulator 30 restrict each other and improve the connection strength between the two.

[0021] The insulator 30 extends to one end of the housing 10 close to the welding point, and the insulator 30 has a avoiding groove 32 corresponding to the fixing strip 21, so that the fixing strip 21 can keep in contact with the housing 10, and the insulator 30 is also used to limit the fixing strip 21.

[0022] A thickened area 12 is provided at one end of the housing 10 near the solder joint, and the thickened area 12 protrudes from the surface of the housing 10, and the height of the fixing bar 21 is less than or equal to the thickness of the thickened area 12. The thickness of the rear of the bracket housing 10 is used to improve the anti-bending performance of the connector body, and the PCB board 20 is not broken in the middle. The height of the fixing bar 21 is set to be less than or equal to the thickness of the thickened area 12 to ensure the consistency of the entire exterior, and to avoid the fixing bar 21 being too high and protruding from the housing, which is easy to cause wear during use.

[0023] The utility model provides a connector structure with an anti-dropping shell. When assembling the connector, a PCB board is inserted into the shell, and one end of the PCB board extends out of the shell. A fixing strip on the PCB board contacts one end of the shell. The fixing strip is firstly welded to the shell to fix the PCB board to the shell. People can directly observe the welding condition of the fixing strip and the shell from the outside, thereby avoiding the occurrence of cold solder joints. Then, an insulator is poured into the shell by injection molding to form an insulating partition. Meanwhile, the PCB board and the shell are further reinforced, thereby ensuring the strength of the connector and avoiding damage to the PCB board.

[0024] 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 protection scope 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.
