Abstract
Provided is a breaker plug-in type binding post, comprising a fixed binding post arranged upon a drawout chassis and a moving binding post arranged upon the breaker body, wherein the lower end of the fixed binding post is provided with multiple rows of fixed interfaces, with each fixed interface being provided with a fixed binding post seat; the moving binding post is provided with multiple rows of moving interfaces corresponding to the fixed interfaces, with each moving interface being internally provided with a moving binding post head stretching out the moving interface; the moving binding post head is made of metal material; the fixed binding post seat is provided with a hunch-up elastic sheet metal thereon; the moving binding post head is provided with a horizontal contact plane thereon; and the sheet metal is contacted with the contact plane when the breaker secondary loop is switched on. The breaker plug-in type binding post features low requirement for connecting precision of the binding post, reliable inserting process, and high integral intensity.
Description
Technical field
The utility model relates to a kind of circuit breaker plug-in connecting terminal, belongs to the low pressure equipment for power transmission and distribution.
Background technology
Circuit breaker is used for connecting the internal circuit and the externally fed circuit of certain limit, and role is equivalent to master switch, for the convenience of Maintenance and Repair, and the normal at present withdrawable circuit breaker that uses.Withdrawable circuit breaker generally comprises two parts, the fixing drawout chassis and the breaker body of drawer type.Circuit on the drawout chassis links to each other with major loop, and the circuit on the breaker body links to each other with external circuit.In order to connect major loop and external circuit, general withdrawable circuit breaker all comprises moving binding post and quiet binding post, and moving binding post is installed on the breaker body; Link to each other with internal circuit; Quiet binding post is installed on the drawout chassis, links to each other with external circuit, through the connection of accomplishing entire circuit that is connected of moving binding post and quiet binding post; The circuit that moving binding post and quiet binding post are connected to form is called secondary circuit.
The binding post of existing withdrawable circuit breaker; Form by moving binding post and quiet binding post; The connection of the connector in the plug-type connecting hole on the metal needle through quiet binding post lower end and the corresponding moving binding post realizes the connection of circuit breaker secondary circuit, is that 03232517.7 Chinese patent " plug-in connecting terminal of withdrawable circuit breaker " is said like application number.Because metal needle cooperates precision prescribed than higher with connector in the connecting hole, so occur easily during insertion misplacing.The situation of metal needle distortion, it is unreliable to contact.
The utility model content
The technical problem that the utility model will solve is to provide a kind of circuit breaker plug-in connecting terminal that required precision is low, the insertion process reliability high, bulk strength is high that connects.
In order to solve the problems of the technologies described above; The circuit breaker plug-in connecting terminal that the utility model provides; Comprise the quiet binding post that is installed on the drawout chassis and be installed in the moving binding post on the breaker body that the lower end of said quiet binding post is provided with the quiet interfaces of many rows, is provided with quiet terminal block in said each quiet interface; Said moving binding post is provided with many rows and the corresponding moving interface of quiet interface; Be provided with the moving binding post head that stretches out said moving interface in said each moving interface, said moving binding post head is processed by metal material, and said quiet terminal block is provided with the elastic sheet metal that arches upward; Said moving binding post head is provided with the contact plane of a level, and said sheet metal contacted with said contact plane when the circuit breaker secondary circuit was connected.
Preferably, said elastic sheet metal is barb-like.
The circuit breaker plug-in connecting terminal of the utility model, the connection required precision is lower, the insertion process reliability high, bulk strength is high.

Embodiment
As shown in Figure 1, the circuit breaker plug-in connecting terminal of the utility model comprises the quiet binding post 1 that is installed on the drawout chassis and is installed in the moving binding post 2 on the breaker body; As shown in Figures 2 and 3, the lower end of quiet binding post 1 is provided with the quiet interface 3 of many rows, is provided with quiet terminal block 4 in each quiet interface 3; As shown in Figure 4, moving binding post 2 is provided with many rows and quiet interface 3 corresponding moving interfaces 5, and the quantity of moving interface 5 and arrangement mode are identical with quiet interface 3; Be provided with the moving binding post head 6 that stretches out moving interface in each moving interface 5, moving binding post head 6 is processed by metal material, and is as shown in Figure 3; Quiet terminal block 4 is provided with the elastic sheet metal 41 that arches upward; As shown in Figure 5, moving binding post head 6 is provided with the contact plane 61 of a level, and elastic sheet metal 41 contacted with contact plane 61 when the circuit breaker secondary circuit was connected; Elastic sheet metal 41 is barb-like; When not being connected with moving binding post head 6, the gib head of elastic sheet metal 41 partly leaves horizontal part one segment distance of quiet terminal block 4, when quiet terminal block 4 is connected with moving binding post head 6; Elastic sheet metal 41 contacts with the surface of moving binding post head 6, and the favorable elasticity of sheet metal 41 can make sheet metal 41 touch the horizontal part of quiet terminal block 4.
In the utility model; The connection of circuit breaker secondary circuit is to cooperatively interact with moving binding post head 6 through quiet terminal block 4 to realize; As shown in Figure 6, when quiet terminal block 4 was connected with moving binding post head 6, the elastic sheet metal 41 of the arched part of quiet terminal block and the contact plane 61 of moving binding post head were in contact with one another; Because the arched part sheet metal has elasticity preferably, thereby has guaranteed that contact portion has enough contact pressures.The utility model connection required precision is lower, the insertion process reliability high, bulk strength is high.
The utility model is replaced contact pin form in traditional terminal structure with rubber-like contact terminal seat; Owing to be that the elastic sheet metal of quiet terminal block and the contact plane of moving binding post head contact; Contact range is big, even installation and cooperation position have certain deviation, still can guarantee reliable contact; Thereby reduced required precision to product manufacturing and installation, improved the reliability of pegging graft.
