Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to an assembled circuit breaker. Background Art

[0002] When a miniature circuit breaker is in use, it is usually necessary to assemble two or more miniature circuit breakers along the width direction. The usual practice is to install multiple circuit breakers side by side through slide rails. However, when only two circuit breakers need to be installed side by side, it is very troublesome to also install a matching slide rail, which increases the installation cost.

[0003] In addition, in the prior art, two circuit breakers are assembled by means of a snap-on structure, in which a protruding snap-on is provided on one side of the circuit breaker housing and a slot is provided on the other side. The snap-on is integrally formed with the circuit breaker housing and is a rigid plastic part. During the assembly process, the protruding snap-on is very easy to break, causing the circuit breaker to lose its assembly capability. Moreover, the protruding setting of the snap-on changes the external structure of the circuit breaker, affects the modular design of the circuit breaker, and also affects the matching use of the circuit breaker with external accessories. Moreover, the matching accuracy of the snap-on and the slot is high, and the production cost is high. Summary of the invention

When two circuit breaker units are assembled side by side, the two circuit breaker units are assembled and connected by correspondingly inserting the tightening parts at both ends of the elastic connecting frame into the sockets on the two circuit breaker units.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] The invention provides an assembled circuit breaker.

[0026] In this embodiment, refer to Figure 1-4 The assembled circuit breaker includes a circuit breaker unit 1 and an elastic connecting frame 2, wherein the elastic connecting frame is rotatably connected to a connecting hole 4 of the circuit breaker unit housing through a rotating shaft 3 in the middle of the elastic connecting frame, and the rotating shaft can move up and down along the length direction of the connecting hole, so that the elastic connecting frame can be lifted or lowered from the connecting hole, and can also rotate relative to the circuit breaker unit housing; the two ends of the elastic connecting frame have tightening parts 5 inclined toward the middle, and the circuit breaker unit is provided with a socket 6 adapted to the tightening part. When two circuit breaker units are assembled side by side, the two circuit breaker units are assembled and connected by correspondingly inserting the tightening parts at both ends of the elastic connecting frame into the sockets on the two circuit breaker units, and the tightening parts are inclined toward the middle, so that after the tightening parts are inserted into the sockets, the two circuit breaker units can be clamped and assembled, and the clamping design helps to improve the assembly stability and firmness.

[0027] In the above technical solution, by providing an elastic connecting frame, two circuit breakers can be quickly and conveniently assembled for use without matching slide rails, which facilitates assembly and reduces installation costs.

[0028] like Figure 2 As shown, when in use, two circuit breakers to be assembled are brought close together, and then the elastic connecting frame is lifted and rotated so that the tightening parts at both ends of the elastic connecting frame are aligned with the sockets, and then the elastic connecting frame is pressed down so that the tightening parts are inserted into the corresponding sockets on the circuit breaker, thereby assembling and splicing the two circuit breakers. The assembly is convenient, the connection is stable, and two or more combinations can be made.

[0029] Specifically, there are two elastic connection frames, which are respectively arranged on the shoulders 7 on the upper and lower sides of the circuit breaker unit. The elastic connection frames are respectively arranged on the shoulders on the upper and lower sides of the circuit breaker unit to improve the assembly stability.

[0030] Specifically, the circuit breaker unit housing includes a left shell 8 and a right shell 9. The right shell is provided with a receiving groove 10 for accommodating the elastic connecting frame. A connecting step 11 is provided in the receiving groove. The connecting hole is arranged on the connecting step.

[0031] By designing the accommodating groove, the elastic connecting frame can be stored in the accommodating groove when the circuit breaker does not need to be assembled. The design of the elastic connecting frame will not change the shape structure of the circuit breaker housing, which is conducive to the modular design of the circuit breaker and will not affect the inherent matching of the circuit breaker and external accessories.

[0032] Specifically, the socket includes a left socket 12 arranged on the left shell and a right socket 13 arranged on the right shell, and the left socket and the right socket are both provided with a bracket groove 14 extending to the outside of the left shell and the right shell; the maximum depth of the accommodating groove and the bracket groove is greater than or equal to the thickness of the elastic connecting frame.

[0033] By designing the bracket groove, after the two circuit breakers are assembled, the entire elastic connecting frame can be completely buried in the bracket groove. After assembly, it will not affect the shape structure of the circuit breaker casing, which is conducive to the modular design of the circuit breaker and will not affect the inherent matching of the circuit breaker and external accessories.

[0034] Specifically, an integrally formed arc-shaped hook portion 15 is provided on the inner side of the top of the tightening portion.

[0035] like Figure 3 As shown, an arc-shaped hook is designed on the top of the tightening part. The arc-shaped hook is elastic due to its structural characteristics, which not only facilitates the insertion of the tightening part into the corresponding socket, but also plays an auxiliary pressing role to improve the stability of assembly.

[0036] Specifically, the tightening portion is inclined toward the middle at an angle a 16 of 10-15°; a screw hole 17 is provided in the middle of the elastic connecting frame, and a threaded section 18 is provided on the top of the rotating shaft to cooperate with the screw hole thread.

[0037] The rotating shaft is threadedly connected to the elastic connecting frame. After the elastic connecting frame is damaged, the elastic connecting frame can be directly replaced without scrapping the entire circuit breaker.

[0038] Specifically, the top of the rotating shaft extending into the connecting hole is provided with an anti-slip step 19 and a clamping step 20, the bottom of the connecting hole is provided with an engaging groove 21 adapted to the clamping step, and the opening of the connecting hole is provided with a limiting step 22 adapted to the anti-slip step.

[0039] like Figure 3 and 4 As shown, the rotating shaft is restricted in the connecting hole by the anti-slip step and the limiting step, and the engaging groove is matched with the pressing step. When the elastic connecting frame is pressed into place, the elastic connecting frame can be prevented from sliding out of the connecting hole.

[0040] Specifically, the elastic connecting frame is made of an elastic metal material, which is not easy to break and has a longer service life.

[0041] Technical personnel should note that although the present invention has been described according to the above specific implementation methods, the inventive concept of the present invention is not limited to this invention, and any modification using the inventive concept will be included in the scope of protection of this patent.
