Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a contact plate. Background Art

[0002] The structure of a circuit breaker generally includes wiring terminals, a magnetic tripping system, a thermal tripping system, a contact system and an arc extinguishing system, among which the contact system is one of the most important components of a circuit breaker. The contact system generally includes a fixedly installed static contact and a moving contact that moves relative to the static contact. A currently more common structure is that the moving contact is installed in a rotatable shaft. When the shaft drives the moving contact to rotate, the moving contact can be closed or separated from the static contact. At the same time, the moving contact is installed in the shaft through a pin shaft and can also rotate relative to the shaft.

[0003] A Chinese patent with publication number CN205230855U discloses a circuit breaker contact piece, including a contact piece body, one end of the contact piece body is a strip contact, one side of the strip contact is provided with a flat contact portion, and the width of the contact portion is greater than the width of the strip contact.

[0004] The above patent has the following problems

[0005] Existing circuit breaker contact pieces may bend, deform, and other problems after long-term use. When the circuit breaker contact pieces are bent or deformed, the circuit breaker cannot function normally, thereby affecting the service life of the circuit breaker. In view of this, we propose a contact plate. Utility Model Content

[0006] The purpose of the utility model is to provide a contact plate to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A contact plate comprising:

[0009] A first reinforcement outer frame, wherein a contact piece body is movably sleeved in the first reinforcement outer frame, a plurality of clamping columns are fixedly installed on both sides of the contact piece body, a plurality of C-shaped clamping slots are opened on both sides of the first reinforcement outer frame, and the plurality of C-shaped clamping slots are movably clamped with the plurality of clamping columns respectively;

[0010] A second reinforcement outer frame, wherein the second reinforcement outer frame is hinged on one side of the first reinforcement outer frame, and a bottom surface of the second reinforcement outer frame contacts a top surface of the first reinforcement outer frame;

[0011] Two side blocks, the two side blocks are respectively fixedly mounted on one side of the first reinforcement outer frame and the second reinforcement outer frame, the top surfaces of the two second reinforcement outer frames are each provided with a through hole, the inner side walls of the two through holes are each provided with an annular inner groove, the two through holes are each provided with two connecting grooves, and the four connecting grooves are respectively connected to the two annular inner grooves;

[0012] A sleeve column, the sleeve column is movably sleeved in the two through holes, two clamping sleeves are fixedly installed on both sides of the sleeve column, and four of the clamping sleeves are respectively arranged in two annular inner grooves;

[0013] A limiting assembly is arranged on the two side blocks and is used for limiting the four ferrules.

[0014] Preferably, the limit assembly includes two pins and four sockets, the four sockets are respectively opened on the top surfaces of the two side blocks, the four sockets are respectively connected to the two annular inner grooves, and the two pins are respectively movably sleeved in the four ferrules and the four sockets.

[0015] Preferably, the connecting groove is a rectangular groove, and the specifications of the ferrule match those of the connecting groove.

[0016] Preferably, the first reinforcement outer frame and the second reinforcement outer frame are the same in shape and size.

[0017] Preferably, a plurality of transverse reinforcement rods are fixedly installed on the bottom surface of the first reinforcement outer frame, a plurality of vertical reinforcement rods are fixedly installed between the plurality of transverse reinforcement rods, and the plurality of transverse reinforcement rods and the plurality of vertical reinforcement rods are arranged in a mesh shape on the bottom surface of the first reinforcement outer frame.

[0018] Preferably, the sleeve column and the four ferrules are an integrally formed structure.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The contact plate has a plurality of transverse reinforcing rods fixedly installed on the bottom surface of the first reinforcement outer frame, and a plurality of vertical reinforcing rods are fixedly installed between the plurality of transverse reinforcing rods. The plurality of transverse reinforcing rods and the plurality of vertical reinforcing rods are meshed on the bottom surface of the first reinforcement outer frame. The plurality of transverse reinforcing rods and the plurality of vertical reinforcing rods are provided to further enhance the hardness of the first reinforcement outer frame, thereby enhancing the hardness of the contact sheet body and enhancing the anti-bending effect of the contact sheet body. The contact sheet body is relatively practical. When the contact sheet body is installed in the first reinforcement outer frame and the second reinforcement outer frame, the contact sheet body is first sleeved in the first reinforcement outer frame. When the contact sheet body is sleeved in the first reinforcement outer frame, the plurality of C-shaped card slots and the plurality of card columns are mutually clamped. The initial installation and positioning of the contact piece body is achieved, and the first reinforcement outer frame and the second reinforcement outer frame are avoided. After the first reinforcement outer frame and the second reinforcement outer frame are closed, the second reinforcement outer frame will block the C-shaped card slot, and the card column cannot be moved out of the C-shaped card slot, thereby enhancing the stability of the contact piece body during installation. After the first reinforcement outer frame and the second reinforcement outer frame are closed, the sleeve column is sleeved in the two through holes. When the sleeve column is sleeved in the two through holes, the four sleeves will enter the two annular inner grooves respectively through the four connecting grooves, and the sleeve column is rotated again. When the sleeve and the connecting groove are misaligned, the cooperation between the annular inner groove and the sleeve will limit the first reinforcement outer frame and the second reinforcement outer frame.

[0021] 2. The contact plate, by setting a first reinforcement outer frame and a second reinforcement outer frame, can protect the contact piece body, enhance the hardness of the contact piece body, and effectively reduce the deformation and bending problems of the contact piece body during use. In addition, by setting a plurality of transverse reinforcement rods and a plurality of vertical reinforcement rods, the hardness of the first reinforcement outer frame is further enhanced, thereby enhancing the hardness of the contact piece body and enhancing the anti-bending effect of the contact piece body, which is more practical.
