Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical equipment manufacturing technology, specifically to a structure for a small residual current circuit breaker aging platform. Background Technology

[0002] Miniature residual current circuit breakers are widely used and produced in large quantities. Before leaving the factory, all products need to undergo an aging test. The traditional aging test involves placing the ends of the wires into the wire clamps of each phase of the circuit breaker and then using a screwdriver to tighten the floating plate of the wire clamps to press the wires together. After aging is completed, the wires must be loosened with a screwdriver. This method seems simple, but it is time-consuming and labor-intensive and is not suitable for mass production.

[0003] Miniature circuit breakers must undergo aging treatment before leaving the factory to improve their reliability and stability. Traditional miniature circuit breaker aging benches use wires to lead into the circuit breaker terminals and tighten the wires with screws. While this method is intuitive and reliable, it is inefficient and often affects normal production due to the large number of miniature circuit breakers produced. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a small residual current circuit breaker (RCCB) aging platform structure. It features simple structure, convenient operation, time and labor saving, and good operational stability. The use of floating contacts and a snap-fit ​​structure improves the connection efficiency between the circuit breaker and the conductor.

The aging treatment seat contains contacts extending to the miniature residual current circuit breaker. Supports are provided on both sides of the contacts. A small shaft is provided in the aging treatment seat to be inserted into the supports and contacts. A screw is provided at the front end of the support. A spring is provided between the screw and the support. A wire is provided between the spring and the screw.

[0007] Preferably, a spring is provided between the spring latch and the contact.

[0008] Preferably, the spring is a torsion spring.

[0009] Preferably, the aging treatment seat is provided with a cover plate at the upper end, and the cover plate is fixedly connected to the aging treatment seat and the aging treatment seat to the base plate with self-tapping screws.

[0010] Preferably, the miniature residual current circuit breaker is provided with a guide rail between itself and the base plate, which is fixed in a snap-fit ​​manner with the miniature residual current circuit breaker.

[0011] Preferably, the guide rail is provided with several bolts that pass through the guide rail in an oblong groove, and the back of the base plate is provided with several nuts that are threadedly connected to the bolts.

[0012] Preferably, one end of the small shaft is provided with a retaining ring that is fitted into the small shaft.

[0013] This invention can achieve the following effects:

[0014] This invention provides a structure for a miniature residual current circuit breaker aging platform.

[0019] Example: Figure 1 and Figure 2 As shown, a miniature residual current circuit breaker (RCCB) aging platform structure includes a base plate 1, an aging treatment seat 2 and a miniature RCCB 9 on the base plate 1, and a guide rail 10 for snap-fit ​​fixing of the miniature RCCB 9 to the base plate 1. Two bolts 15 with oblong grooves through the guide rail 10 are provided on the guide rail 10, and two nuts 16 with threads connected to the bolts 15 are provided on the back of the base plate 1. A cover plate 13 is provided at the upper end of the aging treatment seat 2, and self-tapping screws 14 are used for fixing the cover plate 13 to the aging treatment seat 2 and between the aging treatment seat 2 and the base plate 1. A contact 8 extending to the miniature RCCB 9 is provided inside the aging treatment seat 2, and supports 6 are provided on both sides of the contact 8. A small shaft 7 is provided inside the aging treatment seat 2, which is inserted into the supports 6 and the contact 8. A retaining ring 11 is provided at one end of the small shaft 7 for snap-fit ​​fixing. A screw 3 is provided at the front end of the support 6. A spring latch 5 is provided between the screw 3 and the support 6. A wire 4 is provided between the spring latch 5 and the screw 3. A spring 12 is provided between the spring latch 5 and the contact 8. The spring 12 is a torsion spring structure.

[0020] The aging treatment base 2 is fixed to the base plate 1 by self-tapping screws 14; the miniature residual current circuit breaker 9 is installed on the guide rail 10, which is fixed to the base plate 1 by bolts 15 and nuts 16; the contact 8 is riveted to the small shaft 7 and installed in the hole of the support 6 with clearance fit; the other end is held in place by a retaining ring 11; the spring latch 5 is fixed to the support 6 by screws 3, and the wire 3 is pressed onto the spring latch 5 by screws 4; the spring 12 is a tension spring, one end hooks into the groove of the contact 8, and the other end hooks into the groove of the spring latch 5; the support 6 is fixed to the aging treatment base 2 by back screws; the support 6, small shaft 7, spring latch 5, and guide rail 10 are all iron parts, the contact 8 is a copper part, and the aging treatment base 2 and base plate 1 are insulating parts.

[0021] During operation, under the action of spring 12, the upper end of contact 8 is pressed against the limiting surface B of aging treatment seat 2. The square hole of the miniature residual current circuit breaker 9 is fitted over the lower arc end of contact 8 and installed on the guide rail 10, so that the lower arc end of contact 8 is in close contact with the terminal of circuit breaker 9. This ensures that the working voltage is introduced through the conductor 4, through the spring 5, support 6, small shaft 7, and support 6 to the contact 8, and finally to the terminal of miniature residual current circuit breaker 9, so that normal aging treatment can be carried out.
