The application relates to the technical field of power distribution cabinets, in particular to a wire holder of a circuit breaker.

Background

The circuit breaker is an important device in a switch cabinet, and an inlet end and an outlet end of the circuit breaker are generally provided with 3 interfaces, and each interface is respectively connected with a cable of one phase of three-phase power. In order to connect the circuit breaker with the related incoming cable and outgoing cable, wire holders are configured at the incoming end and the outgoing end of the circuit breaker, each port is generally configured with 3 wire holders, one end of each wire holder is connected with an interface of the incoming end or the outgoing end of the circuit breaker, and the other end of each wire holder is connected to the incoming cable or the outgoing cable. However, the current wire holders are generally produced independently and are independently installed on the circuit breaker, so that each wire holder needs to be positioned once, and the assembly efficiency of the wire holders is low.

To sum up: at present, a wire holder of a circuit breaker, which can reduce the positioning times of the wire holder when the circuit breaker is installed, and increase the assembly efficiency, is lacking in the market.

It should be noted that, for convenience of description, only the portions related to the present utility model are shown in the drawings. Embodiments of the present disclosure and features of embodiments may be combined with each other without conflict.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1 and 4, a wire holder 100 of a circuit breaker of embodiment 1 includes a holder body 101 and a conductive member 102, wherein the conductive member 102 is disposed on the holder body 101, and the conductive member 102 is used for connecting the circuit breaker and a cable to be connected; that is, when the connector 100 of the circuit breaker is disposed on the circuit breaker 10a, the conductive member 102 is inserted into the circuit breaker while the to-be-connected cable is connected to the conductive member 102, so that the conductive member 102 realizes the electrical connection between the to-be-connected cable and the circuit breaker. The circuit breaker is a molded case circuit breaker, and can be an NSX molded case circuit breaker manufactured by Schneider corporation.

The base 101 can stably connect the conductive member 102 to the base 101. Wherein, one side of pedestal 101 is provided with first joint 103, and the opposite side of pedestal 101 is provided with second joint 104, and first joint 103 and second joint 104 can dismantle the connection, so can dismantle the connection through first joint 103 and second joint 104 between pedestal 101 and the pedestal 101, because the both sides of pedestal 101 are provided with first joint 103 and second joint 104 respectively, so a plurality of pedestals 101 can realize connecting in order. The first connector 103 and the second connector 104 can be detachably connected in a bonding, buckling, sliding connection and other modes.

Referring to fig. 2, in a more specific embodiment, the present application provides the following technical solutions: one of the first connector 103 and the second connector 104 is configured as a guide groove 1041, the other is configured as a guide 1031 matched with the guide groove 1041, and the guide 1031 and the guide groove 1041 form a guide fit when the connected housings 101 are connected to each other. For example, the first joint 103 is a guide groove 1041, the second joint 104 is a guide 1031, or the second joint 104 is a guide groove 1041, and the first joint 103 is a guide 1031. In this way, when two adjacent housings 101 are connected, only the guide 1031 needs to be inserted into the guide groove 1041, so that the efficiency is high, both in assembly and disassembly.

Further, the base body 101 is disposed at the same end of the incoming line end or the outgoing line end of the circuit breaker, and the arrangement direction of the base body 101 is perpendicular to the direction of inserting the guiding member into the guiding groove 1041. Therefore, the direction in which the guide 1031 is inserted into the guide groove 1041 is not the direction in which the connector 100 of the circuit breaker is arranged, and the connector 100 of the circuit breaker does not slide out when the connector 100 of the circuit breaker is connected.

Referring to fig. 3, the adjacent housings 101 are horizontally arranged, and the guide 1031 is inserted into the guide groove 1041 in the vertical direction. The Y direction is the arrangement direction of the seat body, and the X direction is the direction of the guide piece inserted into the guide groove.

Referring to fig. 4, the adjacent housings 101 are horizontally arranged, and the guide 1031 is inserted into the guide groove 1041 in a vertical direction. The Y direction is the arrangement direction of the seat body, and the Z direction is the direction of the guide piece inserted into the guide groove.

It can be seen that in the above two embodiments, it is only necessary to ensure that the direction in which the guide 1031 is inserted into the guide groove 1041 is perpendicular to the arrangement direction of the base 101, so that the base 101 and the base 101 can be connected to each other. In the present embodiment, in order to reduce the offset between the housing 101 and the housing 101, the guide 1031 is inserted into the guide groove 1041 along the vertical direction, which affects the mounting of the housing 101.

Referring to fig. 5, more specifically, the guide 1031 includes a connection portion 1031a and a limit portion 1031b, the connection portion 1031a is fixedly connected with the base 101, and the limit portion 1031b is connected with the connection portion 1031 a. The base 101 is provided with a first opening 1041a and a second opening 1041b, and the first opening 1041a and the second opening 1041b are communicated with the guide groove 1041; when the adjacent two housings 101 are connected to each other, the guide 1031 is inserted into the guide groove 1041 along the first opening 1041a, and the connection portion 1031a protrudes from the second opening 1041 b. In this way, the guide 1031 and the guide groove 1041 can be provided in contact with each other. In order to avoid the guide 1031 from being detached from the second opening 1041b, the cross-sectional area of the connection portion 1031a is smaller than the cross-sectional area of the stopper portion 1031 b. Referring to fig. 5, the connection portion 1031a and the stopper portion 1031b are each configured in a rectangular structure.

Referring to fig. 6 to 7, the connection portion 1031a and the stopper portion 1031b are configured to have a triangular cross-sectional shape so that the guide groove 1041, which is matched with the guide 1031, can be configured to have a dovetail groove-like structure. In the present embodiment, the guide 1031 is a portion provided on the base 101 and integrally formed with the base 101 in order to reduce the cost.
