CN-115411561-B - Connector with a plurality of connectors

Abstract

Provided is a connector capable of ensuring the sealing performance of a sealing member. The connector (10, 10A) is provided with a sealing member (13) interposed between the 1 st housing (11, 11A) and the 2 nd housing (12, 12A). The seal member has a seal hole (36) penetrating the seal body (35) in the front-rear direction, and a positioning recess (39) formed in the front surface of the seal body. The 2 nd housing has a pre-assembled component (14, 14A) and an additional component (15, 15A) separate from the pre-assembled component. The pre-assembly member has pre-assembly body parts (41, 41A) arranged in front of the sealing body part, and positioning protrusions (43, 43A) protruding from the rear surface of the pre-assembly body part and entering the positioning recesses. The additional member has peripheral wall parts (52, 52A) that contact the outer peripheral surface of the sealing member.

Description

Connector with a plurality of connectors Technical Field The present disclosure relates to connectors. Background The connector described in patent document 1 includes a housing, a rear holder, and a sealing member (collectively, a rubber plug) disposed between the housing and the rear holder. The seal member has a plurality of seal holes formed therethrough in the front-rear direction. A positioning recess is formed in the front surface of the sealing member. A positioning pin is formed protruding from the rear surface of the housing. In addition, a peripheral wall portion is formed protruding rearward on the outer peripheral edge of the case. The seal member is inserted into the inner side of the peripheral wall portion, and the positioning pin enters the positioning recess, thereby being positioned in the housing. The peripheral wall portion is in close contact with a lip formed on the outer periphery of the seal member. A connector including such a sealing member and a housing is also disclosed in patent documents 2 and 3. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2014-220058 Patent document 2 Japanese patent laid-open No. 2003-151678 Patent document 3 Japanese patent laid-open publication No. 2002-75523 Disclosure of Invention Problems to be solved by the invention In patent document 1, when the positioning pin is inserted into the positioning recess, the sealing member may be pressed by the peripheral wall portion and may be deformed by being compressed radially inward. When the seal member is compressively deformed, the relative positional relationship between the positioning pin and the positioning recess is deviated, and thus, a problem occurs in that the positioning pin is incorrectly inserted into the positioning recess. Accordingly, the present disclosure is directed to providing a connector capable of improving positioning accuracy of a seal member. Means for solving the problems The connector of the present disclosure includes a1 st housing, a2 nd housing, and a seal member disposed between the 1 st housing and the 2 nd housing, the seal member having a seal body portion, a seal hole penetrating the seal body portion in a front-rear direction, and a positioning recess formed in a front surface of the seal body portion, the 2 nd housing having a pre-installed member having a pre-installed body portion disposed in front of the seal body portion and a positioning protrusion protruding from a rear surface of the pre-installed body portion and entering the positioning recess, and an additional member separate from the pre-installed member, the additional member having a peripheral wall portion in contact with an outer peripheral surface of the seal member. Effects of the invention According to the present disclosure, a connector capable of improving positioning accuracy of a seal member can be provided.
