Description

High-current fastening connector

Technical Field

The utility model relates to the connector field technology, in particular to a high-current fastening connector.

Background

The electrical connector bridges two conductors on a circuit so that current or signals can flow from one conductor to the conductor arrangement of the other. An electronic connector is a motor system that provides a separable interface for connecting two sub-electronic systems, simply referred to as a connector, i.e., a bridge between two components that complete an electrical connection between an electrical circuit or electronic machine. The connector is generally an electronic device for charging electronic products or various electric devices, and the electric devices are not needed in life.

Most of the existing American plug connectors wrap and fix the terminals in an injection molding mode, and although the terminals can be fixed in the injection molding mode, the combination of the existing American plug connectors and the terminal is not firm and reliable enough, the terminals are easy to loosen due to the fact that the existing American plug connectors are pulled out and plugged with large force, and moreover, large current cannot pass through the existing American plug connectors. Accordingly, there is a need for improvements over existing American plug connectors.

Disclosure of Invention

In view of the above, the present utility model aims at solving the drawbacks of the prior art, and its primary object is to provide a high-current fastening connector, which can effectively solve the problems that the existing american plug connector cannot pass high current and the combination of the insulation body and the terminal is not firm and reliable.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

a high-current fastening connector comprises an insulating body and terminals; the terminal comprises a contact part, a fixing part and a welding part which are connected in an integrated manner in sequence, wherein the contact part extends outwards at the front end of the insulating body, the fixing part is arranged in the insulating body, the fixing part is provided with an upper fixing hole, the fixing hole is buried in the insulating body, and the welding part extends outwards with the rear end of the insulating body; the terminal is made of copper material.

As a preferable scheme, the rear end of the insulating body is provided with a hollow groove, the welding part extends downwards from the top surface of the hollow groove, and the periphery of the welding part is kept away from the air, so that the welding part is welded with an external mechanism more tightly.

As a preferable scheme, the rear end of the insulating body is provided with a mounting groove for mounting with an external mechanism, and two sides of the mounting groove are provided with clamping grooves, so that the connector and the external mechanism are mounted more firmly and reliably.

As a preferable scheme, the front end of the insulating body is provided with an exhaust groove, and when the connector is plugged, air is discharged from the exhaust groove, so that the connector is plugged more tightly.

As a preferable scheme, the contact part is provided with a through hole, so that the matching performance with the matching terminal is enhanced, and the contact part is prevented from falling off.

Compared with the prior art, the utility model has obvious advantages and beneficial effects, and in particular, the technical scheme can be as follows:

the fixing holes are formed in the fixing parts and buried in the insulating body, so that the terminal is matched with the insulating body more firmly and reliably; and the matched terminal is made of copper, so that the conductivity of the terminal is enhanced, and the connector can pass through high current.

In order to more clearly illustrate the structural features and efficacy of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings and examples.
