Abstract

The utility model discloses a waterproof and dustproof electrical connector. The waterproof and dustproof electrical connector comprises a male end and a female end which are mutually matched with each other; the same number of elliptic terminal inserted holes are formed at the non-abutting ends of the female end and the male end respectively; the terminal inserted holes are elliptic; and the cross sectional area of each terminal inserted hole is reduced while the waterproof and dustproof functions are not impacted. Therefore, the material cost is saved; when in use, the assembly space is saved; and the electrical connector is particularly applicable to automobiles.

Description

The water proof and dust proof electrical cnnector

Technical field

The utility model relates to a kind of water proof and dust proof electrical cnnector.

Background technology

Traditional electrical cnnector is not to be with sealing ring and sealing stifled mostly, does not have the square jack electrical cnnector of functions of waterproof and dustproof, therefore, does not have dustproof and waterproof, in use very easily is subjected to the intrusion of dirt, water and causes damage.And the electrical cnnector that has functions of waterproof and dustproof at present all is to adopt circular socket holes, and small product size is bigger, and materials used is more, and manufacturing cost is higher.

The utility model content

Technical problem to be solved in the utility model provides a kind of water proof and dust proof electrical cnnector, and volume is less when having functions of waterproof and dustproof, and manufacturing cost is lower.

For solving the problems of the technologies described above, water proof and dust proof electrical cnnector of the present utility model comprises the male end and female end of mutual coupling, and the non-butt end of male end, female end is equipped with the same number of terminal insertion hole, and terminal insertion hole is oval.Described male end is provided with the lock platform, and described female end is provided with and locks the latch hook that platform is complementary, and is furnished with sealing ring on the end face of female end butt end.

Be respectively equipped with single hole, two holes, three holes and above terminal insertion hole on the described complete male end and female end.

The utlity model has following advantage:

1. terminal insertion hole is oval, has reduced the area of section of terminal insertion hole when not influencing functions of waterproof and dustproof, thereby has reduced the volume of product, has reduced the material use amount, and then has saved material cost, is very suitable for using on automobile.

2. the male end and female end that is arranged so that of latch hook and lock platform cooperates closely, has prevented to occur loosening phenomenon between the male end and female end, and then has avoided the generation of loose contact phenomenon.The setting of sealing ring can't be infiltrated dirt, water from the seam crossing of male end and female end butt end.

3. on the complete male end and female end respectively correspondence be provided with single hole, two holes, three holes and above terminal insertion hole, can satisfy the user demand of various hole counts.

Embodiment

Extremely shown in Figure 9 as Fig. 1, water proof and dust proof electrical cnnector of the present utility model comprises the female end 2 and the male end 3 of mutual coupling, the non-butt end of female end 2, male end 3 is respectively equipped with oval terminal insertion hole 4, female end 2 is provided with lock hook 6, male end 3 is provided with the lock platform 7 that is complementary with lock hook 6, also is provided with sealing ring 8 on the end face of female end 2 butt ends.Wherein, the number that terminal insertion hole 4 is provided with on male end 3 and female end 2 is identical, can be depicted as every end as Fig. 1 to 9 and establish two, also can establish three as Figure 10, every end shown in Figure 11, can also as Figure 12 every end shown in Figure 13 establish four and shown in Figure 14,15 every end establish five, can certainly be arranged to other number as required.

During use, should adopt the ovaloid seal that is complementary with terminal insertion hole 4 stifled, to seal stifled being enclosed within on the terminal wire that processes earlier, to seal stifled then and terminal insertion terminal insertion hole 4 (comprising the terminal insertion hole 4 on male end 3 and the female end 2), sealing this moment is stifled will to be compressed between terminal and the terminal insertion hole 4, thereby prevent that dirt, water etc. from infiltrating from the seam crossing between terminal insertion hole and terminal; Be butt joint male end 3 and female end 2 at last, female end 2 is inserted in the male end 3 that the latch hook 6 on the female end 2 tangles the lock platform 7 on the male end 3 naturally, thereby realize the reliable self-locking of male end 3 and female end 2.Also be provided with sealing ring 8 on the mating surface of female end 2 and male end 3, after male end 3 and female end 2 lockings, sealing ring 8 relies on the tension of self to seal up the peripheral clearance of male end 3 and female end 2 docking sites, the stifled dependence of sealing self tension blocks the slit of terminal insertion hole 4 oral areas, thereby has realized the function of waterproof and dustproof more reliably.

Claims
