Abstract
The utility model provides a novel drawer-type breaker busbar, and mainly solves problems that present busbar is easily in poor contact with bridge contacts and not firmly connected with mechanism housings. The novel drawer-type breaker busbar is characterized in that both sides of a busbar body (1) are provided with L-type connection boards (2), the L-type connection boards (2) are fixed on the busbar body (1) through screws and provided with fastening connection holes (3), and a bottom of the busbar body (1) is provided with a long-strip clamp connecting block (4). The novel drawer-type breaker busbar is provided with the clamp connecting block and the L-type connection boards, and guarantees that the busbar can be contacted with the bridge contacts, and at the same time be firmly connected with the mechanism.
Description
Technical field
The utility model relates to a kind of busbar, is specifically related to a kind of Novel drawer formula circuit breaker busbar.
Background technology
Circuit breaker is a kind of existing hand switch effect, can automatically transship again and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; do not start continually asynchronous motor; power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally do not need to change parts, therefore obtain a wide range of applications.
Withdrawable circuit breaker has the dual-use function of circuit breaker and isolator.The jockey of circuit breaker mainly is made of bridge-shaped contact, bearing and busbar.The bridge type contact is fixed on the support, and the centre of bridge type contact is provided with fastening spring, and busbar inserts between the bridge type contact, and the busbar surface is provided with groove, and by described groove, busbar is connected on the mechanism shell.Because the surface of bridge type contact and busbar is all more smooth, the long-term use, fastening spring is easily tired, causes the busbar of bridge-shaped contact and busbar loose contact and clamping easily loosening, adopts above design, will affect mechanism's normal operation.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of Novel drawer formula circuit breaker busbar, has mainly solved existing busbar and has been connected unstable problem with mechanism shell with the easy loose contact of bridge type contact and busbar.
The technical scheme that the utility model adopts is: a kind of Novel drawer formula circuit breaker busbar, comprise the busbar body, described busbar body both sides are provided with the L-type connecting plate, described L-type connecting plate is fixed by screws on the busbar body, described L-type connecting plate is provided with and is fastenedly connected the hole, and described busbar body bottom is provided with the strip clamping block.
Described busbar body is provided with four wiring holes.
Described busbar body surface is provided with some square grooves.
The beneficial effects of the utility model are: be provided with clamping block and L-type connecting plate, when having guaranteed busbar and bridge type contact, busbar firmly be connected with mechanism.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the scheme of installation of the utility model and bridge type contact.
1-busbar body among the figure, the 11-wiring hole, 2-L type connecting plate, 3-is fastenedly connected the hole, 4-strip clamping block, 5-square groove.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Such as Fig. 1 in conjunction with shown in Figure 2, a kind of Novel drawer formula circuit breaker busbar, comprise busbar body 1, described busbar body 1 both sides are provided with L-type connecting plate 2, described L-type connecting plate 2 is fixed by screws on the busbar body 1, described L-type connecting plate 2 is provided with and is fastenedly connected hole 3, and described busbar body 1 bottom is provided with strip clamping block 4.
Described busbar body 1 is provided with four wiring holes 11.Be used for the connection of wire.
Described busbar body 1 surface is provided with some square grooves 5.Increase the friction on busbar body 1 surface, make pressing plate compress more securely wire.
The concrete use of the utility model is as follows: during installation, screw is screwed into L-type connecting plate 2, busbar body 1 is fixed on the mechanism shell; Strip clamping block 4 snaps between the bridge type contact, even fastening spring is tired, also can guarantee contacting of busbar and bridge type contact.
The beneficial effect of utility model is: be provided with strip clamping block and L-type connecting plate, when having guaranteed busbar and bridge type contact, busbar firmly be connected with mechanism.
