Description

Copper cap inside a fuse

technical field

The utility model relates to an overload protection element, in particular to an inner copper cap of a fuse.

Background technique

The existing fuse is mainly composed of an insulating shell and copper caps connected to both ends of the shell. There is a fuse in the shell, and metal pins are set on the copper cap. Most of the metal pins extend horizontally toward both ends. Special tools are required, which are cumbersome and can easily cause the copper cap and fuse to break and be damaged during installation. Therefore, how to solve the above problems has become an urgent problem to be solved.

Utility model content

The technical problem to be solved by the utility model is to provide a fuse inner copper cap that realizes rapid installation and tight electrical connection and fixation.

In order to solve the above-mentioned technical problems, a copper cap in a fuse of the present invention includes a vacuum glass tube and a copper cap connected to both ends of the glass tube, and metal pins are arranged on the copper cap, wherein: between the copper cap and the glass tube An inner copper cap is provided, the outer end surface of the inner copper cap is connected to a metal pin, and a fuse is arranged between the inner copper caps.

The above-mentioned inner copper cap of a fuse is set on the inner copper cap, and the copper cap and the inner copper cap are connected through metal pins.

In the above-mentioned inner copper cap of a fuse, a fuse placed obliquely is arranged in a glass tube.

In the utility model adopting the above-mentioned technical scheme, since an inner copper cap is provided between the glass tube and the copper cap, when the fuse is installed, the inner copper caps are arranged at both ends of the fuse, and the inner copper cap and the fuse are inserted in the glass tube. The copper cap physically deforms the inner copper cap and the glass tube into one, achieving the technical effect of tight electrical connection and fixation. The metal pins form a preset external wiring body to facilitate effective electrical connection with the socket body. The utility model has the technical effects of simple and convenient operation and improved working efficiency.

Description of drawings

The utility model will be described in further detail below in conjunction with the embodiments in the accompanying drawings, but it does not constitute any limitation to the utility model.

Fig. 1 is a structural representation of the utility model;

FIG. 2 is a schematic cross-sectional structure diagram of FIG. 1 .

detailed description

Referring to Figures 1 to 2, a copper cap in a fuse includes a vacuum glass tube 1 and a copper cap 2 connected to both ends of the glass tube 1, and the copper cap 2 is provided with a metal pin 21, wherein: the copper cap 2 An inner copper cap 3 is arranged between the glass tube 1 and the outer end surface of the inner copper cap 3 is connected to a metal pin 21 , and a fuse 11 is arranged between the inner copper cap 3 .

The copper cap 2 is sleeved on the inner copper cap 3 , and the copper cap 2 and the inner copper cap 3 are connected through metal pins 21 .

Inside the glass tube 1 is provided a fuse 11 placed obliquely.

When the utility model is specifically installed, since the inner copper cap 3 is provided between the glass tube 1 and the copper cap 2, when the fuse is installed, the inner copper cap 3 is set at both ends of the fuse 11, and the inner copper cap 3 and the fuse 11 Inserted in the glass tube, the copper cap 2 physically deforms the inner copper cap 3 and the glass tube 1 into one, achieving the technical effect of tight electrical connection and fixation. The externally connected metal pins 21 form a preset external wiring body to facilitate effective electrical connection with the socket body.

The embodiments described above are only preferred implementations of the present utility model. It should be pointed out that those skilled in the art can make some structural adjustments and improvements without departing from the principle of the utility model, and these should also be regarded as belonging to the protection scope of the utility model.
