Technical Field

[0001] This utility model relates to the technical field of automatic reset protectors, and in particular to an installation structure for an automatic reset protector. Background Technology

[0002] Overload protectors are widely used circuit protection devices that can disconnect the circuit in time when an overload or short circuit occurs, making control convenient and improving user safety.

[0003] Chinese Patent No. CN214672268U, authorized on November 9, 2021, discloses a utility model patent entitled "An Overload Protection Device with Indicator Light". It includes a protective shell, pin 1, pin 2, and pin 3. The protective shell contains a metal spring and a circuit board. The metal spring has a moving contact, and one end of the metal spring has a button base. The button base is vertically connected to the side wall of the protective shell. The bottom side of the button base has a slot 1 that matches the metal spring. A button body is fixed to the top of the button base, penetrating the top of the protective shell and located outside the shell. The other end of the metal spring is fixedly connected to one end of pin 1. One end of pin 1, one end of pin 2, and one end of pin 3 are detachably installed inside the protective shell. The end of pin 2 inside the protective shell has a stationary contact corresponding to the moving contact. Pins 1, 2, and 3 are all electrically connected to the circuit board, which has an indicator light. The other ends of pins 1, 2, and 3 all penetrate the protective shell and are located at the bottom of the protective shell.

[0004] As can be seen from the above patents, in the prior art, overload protectors and sockets are basically separate units. When the socket needs to have overload protection function, it is often necessary to install the overload protector and the socket, which is troublesome. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the existing technology in which the installation and operation of overload protectors and sockets are cumbersome, and provides an easy-to-install installation structure for an automatic reset protector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An installation structure for an automatic reset protector, comprising:

[0008] case;

[0009] The input pin has one part located inside the housing and detachably connected to the housing, and the other part passing through the housing and located outside the housing;

[0010] A metal carrier plate, one part of which is detachably connected to the housing and located inside the housing, and the other part which penetrates the housing and is located outside the housing and is integrally formed with a socket hardware component; the part of the metal carrier plate located inside the housing is fixed with a stationary contact.

[0011] A metal spring, located inside the housing, has one end fixedly connected to the portion of the input pin located inside the housing, and the other end fixed with a moving contact that corresponds vertically to the stationary contact. When the circuit is connected, the moving contact contacts the stationary contact, and the current flows from the input pin through the metal spring, metal carrier, and socket hardware into the appliance plug. In case of overload, the metal spring heats up and deforms, causing the moving contact on the metal spring to automatically spring open and separate from the stationary contact, thus disconnecting the current and protecting the appliance from damage. After cooling down, the metal spring automatically resets, improving user safety. This design integrates the overload protector with the socket hardware, facilitating installation.

[0012] Preferably, the housing includes an upper shell and a lower shell. The portion of the input foot located inside the housing and the portion of the metal carrier plate located inside the housing are detachably and fixedly connected to both ends of the upper shell. The lower shell is L-shaped, with one side of the lower shell matching the side of the upper shell and several insertion shafts fixed perpendicularly along its edge in the circumferential direction. The side wall of the upper shell has several insertion holes that match the insertion shafts one by one. The lower shell is fixed to the upper shell by interference fit between the insertion shafts and the insertion holes, forming a cavity together. The other side of the lower shell matches the bottom of the upper shell. The installation structure of the upper and lower shells is simple and easy to operate, requiring only the insertion shafts to be inserted into the corresponding insertion holes for interference fit, which also helps to save costs.

[0013] Preferably, the top of the upper shell has a slot that matches the metal carrier plate. The slot is located on the side of the upper shell. The metal carrier plate is L-shaped. One side of the metal carrier plate is inserted into the slot and fixed inside the top of the upper shell. The stationary contact is fixed to one side of the metal carrier plate. The side wall of the slot has a clearance notch that matches the stationary contact. The other side of the metal carrier plate passes through the top side wall of the upper shell and is located outside the cavity, where it is fixedly connected to the socket hardware to form an integral unit. The clearance notch facilitates the contact or separation of the moving contact and the stationary contact. After the metal carrier plate is inserted into the slot, it can be fixed by a spring clip or other means.

[0014] Preferably, the top of the upper shell is provided with a second slot that matches the input foot. The second slot is located on the side of the upper shell, and the first and second slots are located at opposite ends of the upper shell. The input foot is L-shaped. One side of the input foot is inserted into the second slot and fixed inside the top of the upper shell, while the other side of the input foot passes through the top side wall of the upper shell and is located outside the cavity. An L-shaped slot that matches one end of a metal spring is integrally formed on the side of the input foot fixed inside the top of the upper shell. One end of the metal spring is inserted into the L-shaped slot and fixedly connected to the input foot. The side wall of the second slot is provided with a clearance notch that matches the L-shaped slot. The metal spring can be fixed by interference fit or other fixing methods when inserted into the L-shaped slot; the input foot can be fixed by pressing with the lower shell or other methods after being inserted into the second slot.

[0015] The beneficial effects of this utility model are: it improves the user's safety performance; this solution integrates the overload protector and the socket hardware into one unit, achieving the purpose of easy installation; the installation structure of the upper and lower shells is simple and easy to operate, and can be fixed by inserting the pin into the corresponding socket through interference fit, which also helps to save costs.

The lower housing 9 is L-shaped. One side of the lower housing 9 matches the side of the upper housing 8, and several insertion shafts 10 are fixedly fixed along its edge in a circumferential direction. The side wall of the upper housing 8 is provided with several insertion holes 11 that match the insertion shafts 10 one by one. The lower housing 9 is fixed to the upper housing 8 by the interference fit between the insertion shafts 10 and the insertion holes 11 to form a cavity. The other side of the lower housing 9 matches the bottom of the upper housing 8.

[0025] The top of the upper shell 8 is provided with a slot 12 that matches the metal carrier 3. The slot 12 is located on the side of the upper shell 8. The metal carrier 3 is L-shaped. One side of the metal carrier 3 is inserted into the slot 12 and fixed inside the top of the upper shell 8. The stationary contact 5 is fixed on one side of the metal carrier 3.
