Problems solved by technology
[0009] With regard to the proposal of Patent Document 1, since the escape groove is provided near the outer edge of the lead wire sealing member, the sealing material can retreat for the wire insertion hole provided on the outer peripheral side of the lead wire packing member, but for the wire insertion hole provided on the outer peripheral side the position of the wire insertion hole, the sealing material cannot back off
[0010] According to the proposal of Patent Document 2, when the small-diameter portion of the wire insertion hole is arranged on the insertion side of the contact, the contact collides with the sealing material around the small-diameter portion, and the insertion operation of the contact becomes difficult. In addition, if you try to forcefully insert it, it may cause the rubber to crack

Embodiment Construction
[0030] Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
[0031] like Figure 1~Figure 3 As shown, the waterproof connector 10 of the present embodiment includes a plurality of female contacts 1 ( image 3 ), the inner case 20 , the holder 40 , and the outer case 60 that accommodates the inner case 20 and the holder 40 . When the waterproof connector 10 is fitted with the counterpart connector 80 , the contacts 1 are electrically connected to the plurality of male contacts 2 held by the counterpart connector 80 , respectively. The waterproof connector 10 is provided with the sealing member 23 between the counterpart connector 80 and the wire seal 30 in the inner housing 20, thereby preventing the intrusion of water into the interior. In the following description, the side where the waterproof connector 10 and the counterpart connector 80 are fitted to each other is defined as the front, and the side where the elec...

A wire seal for a waterproof connector having a seal body with a mating end surface and a terminal end surface, a plurality of wire insertion passageways extending through the seal body from the mating end surface to the terminal end surface, inner seal projections disposed on an inner peripheral wall of each of the wire insertion passageways, and relief grooves disposed on the mating end surface and the terminal end surface between adjacent wire insertion passageways.
Description
technical field [0001] The present invention relates to a wire seal attached to a waterproof electrical connector (hereinafter, simply referred to as a connector), and a waterproof connector using the wire seal. Background technique [0002] Regarding a waterproof connector, a configuration in which a lead wire seal or a sealing member called a collective rubber plug is provided in the connector housing in order to prevent the intrusion of water and the like from the outside is known. The wire seal is provided with a wire insertion hole at a position corresponding to each of the plurality of contacts (terminal metal parts) held by the connector housing, and the contact is inserted through the wire insertion hole to hold the contact If the cavity is formed, the electric wire connected to the contact is in close contact with the sealing protrusion provided around the electric wire insertion hole, thereby ensuring waterproofness. [0003] Sometimes the contacts connected with ...
