The purpose of the utility model can be realized through the following technical scheme:

the utility model provides a circuit breaker port wiring board, is including port section, interlude and the wiring section that connects gradually, the tip of wiring section is equipped with the jack, and it has the sawtooth to distribute in the jack, and the tip of wire inserts this jack and wiring board and connects.

Further, the jack is rectangular, and the end of the wire is a rectangular block.

Further, the saw teeth are distributed on the inner sides of the four sides of the jack.

Furthermore, the saw teeth are symmetrically distributed on the inner sides of two sides of the jack in pairs.

Furthermore, both sides of the wiring section are provided with concave arcs which are distributed on both sides of the jack.

Furthermore, the intersection edge of the insertion surface of the insertion hole and the insertion surface of the connection section is of a chamfer structure.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses a set up the jack on the wiring board, connect the connected mode of wiring board and wire by traditional soldering and change into inserting the connection, can not have the residue problem after the tin welding, assembly process is simple and convenient moreover, and production efficiency is high.

2. The sawtooth is arranged in the jack and used for clamping the end part of the wire, so that the strength and the stability are improved.

3. A chamfer structure is arranged on one inserting side of the wiring section, so that the wiring section has a guiding effect, an operator can conveniently insert the wiring section, and the front side and the back side of the wiring section can be conveniently distinguished.

4. The both sides of wiring section are equipped with the indent arc, make this part wiring section have certain elasticity, and the wiring section can outwards carry out certain expansion after the wire tip inserts the jack, improves joint strength and stability.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example one

As shown in fig. 1 to 3, the present embodiment provides a circuit breaker port terminal block 1, which is fixed in a housing 3 of a circuit breaker and includes a port section 11, an intermediate section 12 and a wiring section 13 connected in sequence. The port section 11 is arranged in the connecting terminal 31, the middle section 12 is used for being connected with a clamping plate in the shell 3 to form fixation, and the wiring section 13 is used for connecting the internal lead 2.

At the end of the terminal section 13, a receptacle 131 is provided, in which receptacle 131 serrations 132 are distributed. The end of the wire 2 is inserted into the insertion hole 131 and connected to the terminal block 1. The insertion hole 131 is rectangular in this embodiment, and the end of the lead 2 is rectangular. The saw teeth 132 are symmetrically arranged on the inner sides of the two sides of the insertion hole 131 two by two. Concave arcs 134 are arranged on two sides of the wire connecting section 13, and the concave arcs 134 are distributed on two sides of the insertion hole 131. The shape of the concave arc 134 provides a certain elasticity to the segment 13 of the portion, and the terminal 13 expands outward when the end of the lead wire 2 is inserted into the insertion hole 131. The intersection edge of the insertion face of the insertion hole 131 and the terminal 13 is a chamfered structure 133.

The present embodiment has the following advantages: firstly, convenient assembling, raise the efficiency: the lead 2 is directly penetrated in the jack 131, and the lead 2 is easily inserted into the jack 131 due to the guiding function of the structure 133; the sawtooth 132 is arranged in the jack 131 to fix the end part of the lead 2 in which tea is put; the embodiment changes the tin soldering connection mode of the traditional wiring board 1 and the lead 2 into the plug connection mode, does not have the residue problem remained after tin soldering, and has simple and convenient assembly process and high production efficiency. Secondly, the cost is reduced: the solder wire is not used, and the cost of purchasing auxiliary materials is saved.

Example two

As shown in fig. 3, the difference between the present embodiment and the first embodiment is that the serrations 132 are distributed on the inner edges of the four sides of the insertion hole 131. The specific shape of the insertion hole 131 is not limited, and the insertion hole and the end of the wire can be matched, and the insertion hole is preferably rectangular, so that the processing and the production are convenient.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
