Description

Plug-in plastic shell adapter

Technical Field

The utility model belongs to the technical field of moulded case circuit breaker, particularly, relate to bayonet moulded case adapter.

Background

The molded case circuit breaker can automatically cut off the current after the current exceeds the trip setting. Plastic housing refers to the use of plastic insulators as the outer housing of the device to isolate the conductors from each other and from the grounded metal parts. Molded case circuit breakers typically contain a thermo-magnetic trip unit, while large molded case circuit breakers are equipped with solid state trip sensors. The tripping unit comprises: thermomagnetic trip and electronic trip.

The adapter is a common electric connector in low voltage distribution equipment, and its effect is with electrical components overlap joint on electrified generating line copper bar, need not to connect the inlet wire cable, and partly utilize the copper post to be connected with the circuit breaker switching behind the circuit breaker board among the prior art, but when this mode actual operation, the mounting means is comparatively loaded down with trivial details, and is consuming time longer, and traditional copper post size is longer relatively, and this just leads to the cost relatively higher.

An effective solution to the problems in the related art has not been proposed yet.

Therefore in order to solve the above problems, the utility model provides an inserted moulded case adapter.

Disclosure of Invention

An object of the utility model is to provide a bayonet adapter of moulding shell to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: plug-in moulded case adapter, including moulded case circuit breaker and adapter, the outside of adapter is plastic base, the internally mounted of adapter has three group's cross-over connection copper bars, circular socket is installed on the top of cross-over connection copper bar, the top outside annular of circular socket embolias installs the spring, the internally mounted of circular socket has the screw, the screw with cross-over connection copper bar through connection, threaded connection has the nut on the screw, the nut sets up the bottom of cross-over connection copper bar.

Furthermore, three groups of copper bars are installed on one side of the bottom end of the molded case circuit breaker.

Furthermore, screw holes are preset in one ends of the three groups of copper bars, and the copper bars are fixed to the wiring ends of the molded case circuit breaker through screws.

Further, the three groups of the bridging copper bars are divided into three sizes, namely a long size, a medium size and a short size.

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

1. the utility model discloses in, the spring ring shape embolias circular socket oral area, fix circular socket on the cross-over connection copper bar with the screw, according to the length of above step fixed adapter respectively, in, short cross-over connection copper bar, then pack the cross-over connection copper bar into the plastic base of adapter, cover the plastics lid, the product equipment is accomplished, then only need to moulded case circuit breaker together with the bar copper insert the circular socket of adapter in, the installation screw of fixed moulded case can, this structrual installation mode is simple swift, the assembling process is simple swift, can improve work efficiency.

2. The utility model discloses in, compare with traditional cross-over connection copper pipe according to, the cost reduces to some extent relatively, and the essential cost embodies at the length of bar copper and the screw of fixed bar copper.

3. The utility model discloses in, the bar copper is better with the bigger heat dissipation of circular socket area of contact, and the temperature rise accords with the standard requirement.
