Abstract

Provided is a branch connector capable of achieving desired waterproofing functionality by supporting the waterproofing gel in a compressing manner, while stably maintaining a closed state by reducing repulsive force acting in an opening direction of a pair of split housings. The pair of split housings (a first split housing ( 10 ) and a second split housing ( 20 )) includes a gel-escaping space (Z), formed around a gel-supporting space (Y), for accommodating portions of waterproofing gels (a first waterproofing gel ( 70 ) and a second waterproofing gel ( 80 )) pushed out of the gel-supporting space (Y).

First claim

1 . A branch connector comprising:
a pair of split housings capable of opening and closing together;
a relay contact configured, in a closed state of the pair of split housings, to be supported in a central supporting space of the pair of split housings and electrically connected to a cable led to the central supporting space;
a gel-supporting space formed around the central supporting space of the pair of split housings in the closed state of the pair of split housings; and a waterproofing gel supported in a compressed state within the gel-supporting space in the closed state of the pair of split housings,
wherein the pair of split housings includes a gel-escaping space, formed around the gel-supporting space and configured to accommodate a portion of the waterproofing gel pushed out of the gel-supporting space.

2 . The branch connector according to claim 1 ,
wherein one of the pair of split housings includes a waterproofing wall rising toward the other split housing, while the other split housing includes an accommodating wall configured to accommodate the waterproofing wall, and
wherein the gel-escaping space is formed between the waterproofing wall and the accommodating wall.

3 . The branch connector according to claim 1 ,
wherein at least one of the pair of split housings includes an anti-opening wall positioned outside of the relay contact supported in the central supporting space and configured to suppress opening outward of the relay contact.

4 . The branch connector according to claim 3 , wherein the waterproofing gel includes a stepped receiving portion for receiving the anti-opening wall in an accommodating manner.

5 . The branch connector according to claim 1 ,
wherein the waterproofing gel is made up of a pair of waterproofing gels that are supported by the pair of split housings, respectively, in an open state of the pair of split housings and brought into contact with each other within the gel-supporting space of the pair of split housings in the closed state of the pair of split housings.

6 . The branch connector according to claim 5 , wherein the pair of waterproofing gels have the same specifications.
