967067-2 Automobile Connector Seal Rubber

2. Fixed requirements for internal connectors

The inner connector should choose a cover with a buckle or a buckle (see Figures 2 and Figure 3), and prefer to choose a buckle that adapts to the keyhole or long -circular pores, because this buckle has anti -rotation Effects make the electrical connection more reliable. In special cases, you can also use tape binding or other fixed methods.

3. When assembly, you need to pass through the inner connector of the sheet metal hole

For example, the inner connector of the front cabin beam and the body wire, the body thread beam and the back door or the rear bumper, the shape size of the sheet should meet the need for sheet metal perforated. Under normal circumstances, the ratio of the minimum installation width of sheet metal aperture to the cover should be above 1.5: 1.

4. Equipment convenience requirements

Internal connectors with a large number of circuits, especially the composite porous sheaths, due to the large number of terminals, it will be more laborious when the docking, so try to choose a protective cover with a tie structure (see Figure 4)

1. Waterproof

Internal connectors must meet the waterproof level of its installation area.

For example, the indoor is a dry area. The internal connecting parts in this area can meet the requirements with non -waterproof sheets. The part of the front cabin or the four -door waterproof film belongs to the wet area. The inner connector installed in the exposed location of the wet area must be selected.

Some models of the front cabin are designed inside the front cabin, making it in a hidden environment. Although a non -water -proof sheath is selected, this design is also reasonable.

2. Temperature resistance

The temperature resistance level of the internal connector is higher than the ambient temperature at the installation location. The temperature resistance level of the internal connector is related to its material. Select the appropriate material according to the environmental temperature where the internal connection is located. For example, the varieties with a thermal deformation temperature of less than 100 ° C are: PE, PS, PVC, PET, PBT, ABS, PMMA, etc.; Varieties with thermal deformation temperature between 100 and 200 ° C: PP, PVF, PVDC, PSF, PPO and PPO and PC, etc.
