Technical Field

The invention belongs to the technical field of contact boxes, relates to a contact box, and particularly relates to a contact box with a shield.

Background

The contact box is an insulating component applied to various handcart type switch cabinets, and input and output busbars are connected at the contact box. The structure of current contact box is generally including being tube-shape and top confined body, and the bottom of this body is opened and is used for supplying female the row to stretch into, and the lateral part of body runs through in addition and sets up a connection port for supplying another female row to stretch into, and body top inboard still is fixed with the inserts that are used for fixed female arranging, makes female arranging of input and output can realize fixed connection and switch on inside the body.

However, in the actual production process, due to different manufacturers, the situation that the bus bar is too long or has a sharp angle after being processed is easy to occur, so that the surface of the inner cavity of the contact box is clicked. Therefore, experts propose to arrange a baffle at a discharge port of the contact box, and on the basis that a plurality of components such as a busbar and an insert are arranged in the contact box, the baffle is additionally arranged in a limited space, so that the air circulation in the contact box is influenced, the heat dissipation condition in the contact box is influenced, and the safety of the actual use of the contact box is greatly influenced.

Disclosure of Invention

The invention aims to provide a contact box aiming at the problems in the prior art, and solves the problem that the existing contact box is poor in heat dissipation effect.

The purpose of the invention can be realized by the following technical scheme:

a contact box comprises a body made of insulating materials, the body is cylindrical and the top of the body is closed, and the contact box is characterized in that a static contact is further fixed to the top of the body, the static contact is made of metal materials and is of an integrated structure, the inner end of the static contact is located in the body, the outer end of the static contact penetrates through the top of the body and extends out of the body, a first partition portion protruding into a U shape is further arranged on the outer side of the top of the body, and the first partition portion surrounds the outer end of the static contact.

When the contact box is used, one busbar axially extends into the body from the bottom of the body and is connected with the inner end of the static contact, and the other busbar radially extends into the first separating part from the opening of the first U-shaped separating part along the body and is connected with the outer end of the static contact, so that the busbar at the position of the contact box is connected. This contact box is through wearing to establish the static contact at the structure at body top for two female arranging set up respectively in the body inboard and the outside, reduce the inboard spare part of body, provide sufficient heat dissipation space for the body inboard, improved the radiating efficiency. Meanwhile, the static contact which is arranged at the top of the body in a penetrating mode and made of metal materials has good heat conductivity, heat in the body can be conducted out, and the heat dissipation efficiency is further improved. And the setting of partition portion one also provides enough creepage distance for female arranging in the body outside, with female arranging the setting in the body outside for operating personnel can look directly at the connection condition when installing, the connection of being more convenient for.

In the above contact box, an annular shielding net is further disposed in the top of the body, and the shielding net is conducted with the fixed contact. The shielding net is designed on the outer side of the joint of the busbar and the static contact, so that gap discharge between the busbar and three media, namely an insulating part and the static contact, can be eliminated.

In the above contact box, the outer edge of the shielding net further has a cylindrical shielding part bent towards the bottom of the body. The coverage area of the shielding net is increased, and the effect of eliminating discharge is improved.

In the above-mentioned contact box, the outside of the first partition portion has a protruding umbrella skirt, and the umbrella skirt is U-shaped and is disposed around the stationary contact. The umbrella skirt is arranged to further increase creepage distance and ensure the safety and stability of connection use.

In the above-mentioned contact box, the inner side of the top of the body has a second separation portion protruding annularly around the inner end of the static contact. The arrangement of the second separating part can also be used for increasing the creepage distance.

In the above-mentioned contact box, the outer wall of the static contact is tightly abutted against the body to form a seal. The static contact is directly poured in the body, so that the sealing performance between the static contact and the body is ensured.

In the above mentioned contact box, the fixed contact is cylindrical.

Compared with the prior art, the contact box has the following advantages:

1. through wearing to establish the static contact structure that sets up, female branch of arranging input and output establishes inside and outside the body, has reduced the heat and has piled up and this internal spare part volume, has improved the radiating efficiency.

2. The static contact made of the metal material has a good heat conduction effect, heat in the body can be effectively conducted out, and the heat dissipation effect is further improved.

3. The output busbar can be directly connected outside the body, the connection condition can be directly observed, and the connection is more convenient.

The static contact 2 is poured in the body 1, the inner end of the static contact 2 is positioned inside the body 1, the outer end of the static contact 2 penetrates through the top of the body 1 and extends out of the body 1, and the outer wall of the static contact 2 is tightly abutted against the body 1 to form sealing. In this embodiment, the outer wall of the static contact 2 has a concave annular groove for the body 1 to be inserted into, and the static contact 2 has a stepped hole with a small outer part and a large inner part.

The outer side of the top of the body 1 is further provided with a U-shaped protruding separating part I3, and the separating part I3 is arranged around the outer end of the static contact 2. The outer side of the first partition part 3 is also provided with a convex umbrella skirt 6, and the shape and the arrangement direction of the umbrella skirt 6 are the same as those of the first partition part 3, namely the umbrella skirt is U-shaped and is arranged around the static contact 2. Correspondingly, the inner side of the top of the body 1, which surrounds the inner end of the static contact 2, is also provided with a second protruded annular separating part 7.
