Detailed Description

Example 1:

referring to fig. 1 to 5, a connector for preventing a creepage includes a housing 1 and a plurality of pins 2.

The housing 1 is used to fix the pin 2. One end of the whole shell 1 is fixedly connected with the circuit board, and the other end of the shell 1 is fixedly connected with the other part of the connector. In this embodiment, it is preferable that the housing 1 is a female head, and another part of the housing is a male head, and the structure of the male head is not related to the invention point in this embodiment, so that the detailed description is omitted in this embodiment.

The shell 1 comprises an upper chamber 3 and a lower chamber 4, wherein the upper chamber 3 is matched with the male head to realize the effect of connecting and fixing the two.

Go up cavity 3 and be the cavity setting, go up and be equipped with breach 31 on cavity 3's the both ends respectively, two breachs 31 are the symmetry setting, and breach 31 and last cavity 3 set up for the intercommunication, adopt the setting of breach 31 for go up cavity 3 and public connection area between the head increase, thereby increase fixed strength between the two. Further, a second guiding surface 32 is provided on the end of the upper chamber 3 facing the male end, specifically, the end far from the lower chamber 4. In this embodiment, the second guide surface 32 may be an inclined surface or an arc surface, and may be adjusted according to actual requirements.

The lower chamber 4 and the upper chamber 3 are arranged in communication, but in this embodiment, the size of the connection between the two is adapted to the size of the pin 2, so that a sealing effect is achieved.

The lower chamber 4 is provided with a plurality of partition plates 41, one end of each partition plate 41 is connected with the casing 1, and the other end of each partition plate 41 extends vertically downwards, so that the bottom surfaces of the partition plates 41 and the bottom surface of the casing 1 form a coplanar arrangement, wherein the coplanar arrangement specifically means that the two bottom surfaces are located on the same horizontal plane. The partition 41 thus divides the lower chamber 4 into a number of cavities 42, where the number of cavities 42 preferably corresponds to the number of pins 2, i.e. one pin 2 corresponds to one cavity 42. Be equipped with boss 43 on the top inner wall of cavity 42, boss 43 is for extending towards bottom surface one side, and size, the size of this boss 43 can be adjusted according to actual demand. The arrangement of the boss 43 is adopted, so that the contact area between the contact pin 2 and the shell 1 is increased, and the fixing strength of the contact pin 2 is improved. Further, the boss 43 is provided with a first guide surface 431 on the side facing the bottom surface. The first guide surface 431 is provided to facilitate the insertion of the pin 2 into the housing 1.
