Description

Easily assemble miniature circuit breaker casing

Technical Field

The utility model relates to a circuit breaker field especially relates to an easily assemble miniature circuit breaker casing.

Background

The circuit breaker is a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and a current under an abnormal circuit condition within a prescribed time. The circuit breaker often need splice the use when using, and miniature circuit breaker concatenation among the prior art needs to have bulge and shrinkage pool on the circuit breaker shell for the location and the centre is used for wearing the fixed two poles of the earth or multipolar circuit breaker of rivet, and such structure often makes the required mould quantity of circuit breaker processing increase, because the shell of most marginal shell and middle concatenation can not replace, and economic benefits is relatively poor. In addition, the more the splicing stages are, the poorer the splicing firmness is, and the more the splicing stages are, the more the vertical dislocation is caused.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is how to improve circuit breaker casing concatenation firmness, to the above-mentioned technical problem that solves, an easily assemble miniature circuit breaker casing is proposed at present.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an easily assemble miniature circuit breaker casing, includes that first casing and the second of assembling are assembled the casing, first casing and the second of assembling is assembled the casing and is spliced relatively, the first side same position of assembling the casing and the second casing of assembling is provided with the location jack, be provided with fixed contact pin in the location jack, the location jack on the adjacent miniature circuit breaker casing of fixed contact pin fixed connection.

Furthermore, the front end of the first assembled shell and the second assembled shell is provided with a front positioning jack, and the rear end of the first assembled shell and the second assembled shell is provided with a rear positioning jack. The front positioning jack is arranged below the fixing screws at the front ends of the first assembled shell and the second assembled shell.

Furthermore, the rear positioning jack is arranged below the fixing screws at the rear ends of the first assembled shell and the second assembled shell.

Furthermore, a front positioning jack is arranged below the front end fixing screws of the first assembled shell and the second assembled shell, a rear positioning jack is arranged below the rear end fixing screws of the first assembled shell and the second assembled shell, and a fixing contact pin is arranged in the front positioning jack and the rear positioning jack.

Compared with the prior art, the beneficial effects of the utility model are that:

because the positioning jacks are arranged at the front end and the rear end of the shell, the fixed contact pins are inserted into the positioning jacks for limiting and fixing, and the adjacent shells are connected together, the spliced shell can be set to be the same shell, the shells at the edges and the shell in the middle are the same die, and the unified die is adopted for processing, so that the die cost can be saved, and the utilization rate of the shell is greatly improved; and the jacks are adopted for positioning and fixing, so that the contact pins can be arranged deeply, the structure of the spliced shell can be firmer, and the product can be firmly and stably spliced in a multi-pole mode.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, this embodiment discloses an easily-assembled miniature circuit breaker housing, including first casing 1 and second casing 2 of assembling, casing 2 is assembled to first casing 1 and second of assembling relatively, the first casing 1 of assembling and the second side same position of assembling casing 2 are provided with the location jack, be provided with fixed contact pin 5 in the location jack, fixed contact pin 5 fixed connection is the location jack on the adjacent miniature circuit breaker housing.

Preferably, the front ends of the first assembled shell 1 and the second assembled shell 2 are provided with front positioning jacks 3, and the rear ends of the first assembled shell 1 and the second assembled shell 2 are provided with rear positioning jacks 4. The front positioning insertion hole 3 is arranged below the fixing screws at the front ends of the first assembled shell 1 and the second assembled shell 2. And the rear positioning jack 4 is arranged below the fixing screws at the rear ends of the first assembled shell 1 and the second assembled shell 2. The molding method can be that the shell and the shell are molded together by injection molding. Specifically, the fixing bolt at the front end and the fixing bolt at the rear end are arranged on the corners of the shell. For further improvement of stability, positioning insertion holes may be provided at other positions, for example, a triangular insertion hole may be provided at a position corresponding to the positioning insertion holes at the front end and the rear end, so that stability can be improved.

Because the plug pins and the corresponding plug holes are fixed, the plug pins and the plug holes are separated before assembly, the spliced shell can be set to be the same shell, the shell at the edge and the shell in the middle are the same die, and the die is machined by adopting a unified die, so that the die cost can be saved, and the utilization rate of the shell is greatly improved.

More specifically, the first casing 1 of assembling and the second below of assembling the front end set screw of casing 2 are provided with preceding location jack 3, the first casing 1 of assembling and the second below of assembling the rear end set screw of casing 2 are provided with back location jack 4, be provided with fixed contact pin 5 in preceding location jack 3 and the back location jack 4.
