Abstract

The utility model relates to a kind of novel contact configurations, including static contact and moving contact, the static contact is hook-shaped in lying low, and is located at bill end with the moving contact contact point；It is corresponded on the static contact, and arc striking piece is set with moving contact contacting points position；The arc striking piece is L-shaped, extends in front of bill end from the static contact bill end back side.The utility model structure is simple, easily assembles, and production cost is low, improves arc extinction performance.

Description

A kind of novel contact configurations

Technical field

The utility model relates to breaker dynamic/static contact technical field of structures, specifically disclose a kind of novel contact configurations.

Background technique

Traditional dynamic/static contact connection structure is as shown in Figure 1, including moving contact, static contact, connecting plate, being flexible coupling, bracket, bullet Spring and connecting shaft, the structure of contact terminal components are complicated, install troublesome in poeration, this height of production liter.

Utility model content

The goal of the invention of the utility model is: a kind of structure is simple to solve the above problem, easily assembles, is produced into This low novel contact configurations.

The technical solution adopted in the utility model is such that

A kind of novel contact configurations, including static contact and moving contact, the static contact is hook-shaped in lying low, with the dynamic touching Head contact point is located at bill end；It is corresponded on the static contact, and arc striking piece is set with moving contact contacting points position；It is described to draw Arcs are L-shaped, extend in front of bill end from the static contact bill end back side.

Further, the static contact has elasticity with moving contact contacting points position.

In conclusion due to the adoption of the above technical scheme, the beneficial effects of the utility model are:

(1) new structure part is less, and structure is simple, is easy assembly, reduces cost；

(2) increase arc striking piece on static contact, improve arc extinction performance；

(3) have changed static contact angle, increase out away from.

Detailed description of the invention

Fig. 1 is the utility model prior art construction figure；

Marked in the figure: 1, moving contact；2, static contact；3, bracket；4, it is flexible coupling；5, connecting plate；6, spring；7, connecting shaft.

Fig. 2 is the utility model structure chart.

Marked in the figure: 1, moving contact；2, static contact；3, arc striking piece.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

As shown in Fig. 2, a kind of novel contact configurations, including static contact 2 and moving contact 1, the static contact 2 are hook-shaped in lying low (hook includes the neck of hook and hook portion, lying status hook portion opening upwards), is located at bill end with 1 contact point of moving contact；? It is corresponded on the static contact 2, and arc striking piece 3 is set with 1 contacting points position of moving contact；The arc striking piece 3 is L-shaped, from described quiet The 2 bill end back side of contact extends in front of bill end.

The static contact 2 has elasticity with 1 contacting points position of moving contact, and being completely embedded between guarantee dynamic/static contact 1,2 can It leans on.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.

Claims (2)

1. a kind of novel contact configurations, including static contact and moving contact, it is characterised in that: the static contact is hook-shaped in lying low, It is located at bill end with the moving contact contact point；It is corresponded on the static contact, and striking is set with moving contact contacting points position Piece；The arc striking piece is L-shaped, extends in front of bill end from the static contact bill end back side.

2. a kind of novel contact configurations according to claim 1, it is characterised in that: the static contact is contacted with moving contact Point position has elasticity.
