It is connected with temperature-sensing element on the inside of portion, the one end of the temperature-sensing element away from fixed seat is provided with moving contact, under the fixed seat
Insulating base is fixed with the inside of portion, the insulating base is provided with static contact, and the moving contact is set face-to-face with the static contact,
The static contact and fixed seat are connected to wire, and the openend of the shell is connected with solidus seat, and the solidus seat is provided with
Positioning hole, the wire are drawn by the positioning hole.
Preferably, the size of the solidus seat matches with the openings of sizes of the shell, the solidus seat installation by adhering
At the openend of the shell.
Preferably, the side of the solidus seat is provided with fixed card buckle, and the shell aperture end is provided with and the fixed card buckle
The fixation bayonet socket to match, it is intraoral that the fixed card buckle is caught in the fixing card.
Compared with prior art, the beneficial effects of the utility model are：It is caught in the opening of Mini-sized protector shell solid
After line seat, wire can be drawn by the positioning hole of solidus seat, and so as to the extraction location of fixed wire, while solidus seat can also
Protector body is fixed in shell, plays a part of protecting protector body, solidus seat makes wire be separated with shell in addition,
The generation of short circuit phenomenon is prevented.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-5 are referred to, the utility model provides a kind of technical scheme：A kind of contact pin type Mini-sized protector, there is shell
1, the one end of shell 1 is provided with opening, and the inside of shell 1 is provided with fixed seat 2, and fixed seat 2 is semi-surrounding structure, the top of fixed seat 2
Inner side is connected with temperature-sensing element 3, and the one end of temperature-sensing element 3 away from fixed seat 2 is provided with moving contact 4, the inner side of the bottom of fixed seat 2
Insulating base 5 is fixed with, insulating base 5 is fixed in fixed seat 2 by the clamping jaw 12 in fixed seat 2, and insulating base 5 is provided with static contact
6, moving contact 4 is set face-to-face with static contact 6, and static contact 6 and fixed seat 2 are connected to wire 11, and wire 11 is from shell 1
Draw openend.
Solidus seat 7 is connected with the openend of shell 1, the size of solidus seat 7 matches with the openings of sizes of shell 1, solidus
Seat 7 is installed into inside shell 1 from the opening of shell 1, and solidus seat 7 is provided with two positioning holes 8, and static contact 6 and fixed seat 2 are respective
