Description

Technical Field

[0001] The utility model relates to the technical field of fuse sockets, in particular to a structure for preventing a safety clip from loosening in a fuse socket. Background Art

[0002] According to the current hardware connection standards for socket products, the connection and positioning of socket hardware cannot be achieved solely through plastic parts. It must be able to maintain a secure connection even after the plastic melts or decomposes. Many products currently on the market still use hardware positioning methods such as directly snapping hardware positioning parts onto plastic parts, or directly molding hardware parts into plastic parts to position hardware. Although this method can fully meet normal use and has relatively low production costs, it poses a significant safety hazard. In particular, the connection between the fuse clip and the connector and terminal in the fuse socket mostly relies on plastic parts for positioning. The connection itself is generally not tight enough. Under abnormal conditions, the continuous ignition and heating of the connection part can easily cause adverse consequences such as power failure, heating, softening or even melting of the surrounding plastic, and fire. There have also been cases of fire caused by this reason.

[0003] Based on the above reasons, the applicant has improved the positioning structure of the hardware in the fuse socket. Utility Model Content

[0012] In the above technical solution, the safety clip is a U-shaped structure, with first positioning structures adapted to the insulating member provided on both side walls thereof, and the hole groove provided on the bottom thereof.

[0013] In the above technical solution, the connection terminal is an L-shaped structure, one wall of which is provided with the hole groove, and the other wall is provided with a second positioning structure for fixing the cable or the cable connector.

[0020] like Figure 1-2 As shown, the fuse clip anti-loosening structure in the fuse socket is provided with an insulating member on the fuse and a terminal 10 and a fuse clip 20 embedded thereon and conductively connected; a conductive connecting member 30 is also provided in the insulating member, which passes through the fuse clip 20 and the terminal 10 in sequence and connects the two together in series.

[0021] Furthermore, the conductive connector 30 is a columnar structure, and both the safety clip 20 and the terminal block 10 are provided with a hole slot 1 adapted to the conductive connector 30 .

It can be understood that the shoulder 2 can position and limit the terminal 10 and the safety clip 20 so that

[0023] Furthermore, the conductive connector 30 is fixedly connected to the safety clip 20 and the connection terminal 10 or is slidably connected along the circumferential direction.

[0024] In some embodiments of the present invention, the conductive connector 30 is fixed to the connection terminal 10 and / or the safety clip 20 by screwing, riveting or welding.

[0025] In this embodiment, the conductive connector 30 is a square column structure. The safety clip 20 and terminal block 10 are positioned around it and can slide relative to it axially within a certain range, facilitating assembly. In practice, depending on the specific structure of the safety clip 20 and terminal block 10, the three can be fixed together through screwing, riveting, or welding to prevent relative sliding. Alternatively, the conductive connector 30 can be configured as a cylindrical structure, with the shoulders 2 spaced appropriately apart to allow relative sliding within a certain range in the circumferential and axial directions.
