Benefits of technology

[0006] It is the main object of the present invention to provide a packing member, which is compressible and which automatically repairs damage to keep airtight after having been inserted with an external object.
[0007] It is another object of the present invention to provide a packing member, which effectively seals the protected members against dust and moisture.

Problems solved by technology

It is difficult to seal the connecting or sliding faces between mechanical parts or apparatus against external dust and water.
More particularly in an electric connector, it is difficult to seal the electric wires against external dust and water.
If the electric wires of an electric connector are not well sealed, the electric wires tend to be covered with dust and water may leak in the housing of the electric connector, resulting in an error of contact or short circuit.

Embodiment Construction

[0013] Referring to FIGS. 1 and 2, a packing member 10 is shown comprising a pad body 11 and a reinforcing layer 12 formed in the pad body 11. The pad body 11 is molded from silicon rubber. The reinforcing layer 12 is formed of fibers. Selected fibers are mixed with liquid silicon rubber, forming a fluid mixture, which is then injection-molded into the desired packing member 10. The packing member 10 is compressible. The packing member 10 is able to return to its former size and shape after being compressed. The reinforcing layer 12 improves the mechanical properties of the pad body 11.

[0014] Referring to FIGS. 3 and 4 and FIG. 2 again, the packing member 10 can be used in an electric connector 20 to seal electric wires 30. As illustrated, the electric connector 20 comprises a housing 21 and a pressure cover 22. The housing 21 comprises a receiving open chamber 23 in the front side. The packing member 10 is inserted into the receiving open chamber 23 to seal electric wires 30. The ...

Abstract

A packing member formed of fiber-reinforced silicon rubber is disclosed for use in an electric connector and compressed by a pressure cover in the housing of the electric connector to seal electric wires.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to packing members and more particularly, to a compressible packing member, which automatically repairs damage to keep airtight after having been inserted with an external object. [0003] 2. Description of the Related Art [0004] A packing is a sealing or filling material used in connecting or sliding faces between mechanical parts or apparatus to keep airtight or prevent leakage. It has a certain power of deformation. Subject to purpose of use, a packing may have the properties of heat resistance, pressure resistance, corrosion resistance, water resistance, oil resistance, and / or wear resistance. It is difficult to seal the connecting or sliding faces between mechanical parts or apparatus against external dust and water. More particularly in an electric connector, it is difficult to seal the electric wires against external dust and water. If the electric wires of an electric connector ar...
