Abstract

The connector includes a housing and contacts received in the housing. The housing includes a front housing and a rear housing, one end of the contact is fixed in the front housing and the other end of the contact is received in the rear housing. The rear housing includes a base housing and a top housing, the base housing and the top housing being disengageably coupled to each other such that when the base and top housings are separated from each other, the other ends of the contacts are exposed from the housing. This allows easy crimping of the wire onto the contact. Meanwhile, the front end of the contact is secured to the front housing of the connector so that the contact remains stationary relative to the housing when the wire is crimped. Moreover, when the connector's front housing and rear housing are assembled together, the contacts are hermetically received in the connector's housing to prevent external water vapor and dust from entering the housing, thereby ensuring the electrical performance of the connector.

This application claims priority to Chinese Patent Application No. CN201611122901.3, filed with the Chinese Intellectual Property Office on December 8, 2016, the entire disclosure of which is hereby incorporated by reference.

Embodiments of the present disclosure relate generally to connectors, and more particularly to connectors that facilitate crimping of contacts to wires.

Description of Related Technologies

In the prior art, connectors generally include a housing and contacts received in the housing. For connectors with contacts that are crimped onto the wires, the contacts are generally pre-assembled to the housing before being crimped onto the wires. At this time, the end of the contact being crimped is positioned outside the housing to facilitate crimping of the wire onto the contact. After the wire is crimped onto the contact, the contact is pushed completely into the housing to place the contact in the working position, with the crimped end of the contact being received inside the housing.

However, in the prior art, when the contact is in the pre-assembled position, the position of the contact relative to the housing is unstable, and wobbling occurs when the wire is crimped, thereby properly crimping the wire onto the contact. It may not be. Therefore, the operator has to stop the crimping machine to crimp the wire, adjust the position of the contact, and then continue the wire crimping operation, which causes a relatively large time cost.

In addition to this, in the prior art, to allow the contacts to move between the pre-assembled position and the working position, the rear end portion of the housing is completely open, which allows outside water vapor and dust to easily enter the housing interior. This causes the electrical performance of the connector to deteriorate. And, an additional sealing cover will cause additional installation cost.
