Description

A floating, waterproof connector harness assembly

technical field

The present invention relates to the technical field of connectors, and more particularly to a floating and waterproof connector wire harness assembly.

Background technique

Fan connectors are commonly used components in fan modules. They are used to aggregate different numbers of fan wire harnesses into the entire module to form an independent unit, which is then functionally connected to the host. During the mating process of the existing fan connectors, there is a problem that the positioning accuracy is poor and the mating cannot be achieved. At the same time, most of these connectors do not have waterproof function, and the service life is often shortened because they are not waterproof.

In practical applications, the modules are assembled in two directions, positive and negative. In order to meet the needs, a rotatable structure is often used, but such a rotatable structure is expensive and complicated.

The purpose of the present invention is to provide a floating, waterproof connector wire harness assembly to solve the above-mentioned problems in the background art.

In order to achieve the above object, the present invention adopts the following technical solutions:

A floating, waterproof connector wiring harness assembly, comprising an insulator, a sealing ring, a floating screw, a plastic body, a terminal, and a cable, the terminal is fixed in the insulator, and one end of the terminal is used to connect with the pin of the plug-end connector The other end of the terminal is connected with the cable, the sealing ring is sleeved on the outer diameter of the insulator, and the plastic sealing body wraps the terminal, the cable and the insulator.

Further, the plastic sealing body is provided with a mounting end at one end close to the insulator, and the mounting ends on the upper and lower sides of the insulator are respectively provided with guide posts for matching with the sockets of the plug-in connector.

Further, the front end of the guide column is provided with a tapered guide surface.

Further, floating screws are respectively provided on the mounting ends on the upper and lower sides of the insulator.

Further, the outer contour of the insulator and the guide posts disposed on the mounting ends on the upper and lower sides of the insulator adopt a center-symmetric structure, and the terminals are evenly and symmetrically arranged up and down.

Compared with the prior art, the present invention has the following beneficial effects:

1. The present invention has novel structure and strong practicability. The connector harness assembly of the present invention is easy to operate, can be floated, and realizes functions such as comprehensive waterproofing after the plug-in connection. The structure is simple, the cost is low, and the labor efficiency is significantly improved in use. The invention solves the problem that the module cannot be inserted due to poor positioning accuracy during the insertion process through the floating screw and the guide column. Since the floating screw and the guide column are provided, the positioning accuracy of the entire module is relatively low.

2. During the connector insertion process of the wire harness assembly of the present invention, radial waterproof sealing is achieved through the sealing ring and the butt end connector, and the plastic sealing body wraps the terminal, the cable and the insulator to form a seal.

3. The shape of the insulator and the guide column of the present invention adopt a center-symmetric structure, and the terminals are evenly arranged up and down symmetrically, so that the positive and negative rotation of 180° can also be used to complete the electrical function docking.
