Embodiment approach 1

[0067] First, refer to Figure 1A ~ Figure 8C The connector 10 according to Embodiment 1 will be described. The connector 10 according to Embodiment 1 is mounted on a circuit board, for example, and is used by being connected to a counterpart connector (not shown). The connector 10 according to Embodiment 1 has a structure in which an opening 66 for connecting to a counterpart connector is provided on one side, and a part of a contact 12 for communicating with a circuit board formed on a circuit board or the like protrudes from the other side. The contacts are connected. In addition, a gasket 92 for improving airtightness and waterproofness is attached to the outer peripheral side of the opening 66 side of the connector 10 .

[0068] Such as Figure 1A , Figure 1B , Figure 7A as well as Figure 8B As shown, the connector 10 of Embodiment 1 is composed of the following parts: a metal shell 62, and an annular gasket 92 is mounted on the outer peripheral side of the shell ...

Embodiment approach 2

[0093] Next, the main reference Figure 9A ~ Figure 14C A connector 10A according to Embodiment 2 will be described. In the connector 10 of the first embodiment, the housing 18 and the housing 62 are fixed by welding using the fixing member 56 , but in the connector 10A of the second embodiment, welding is not performed when assembling. The case of fixing the casing 18A and the case 62A will be described. In the connector 10A of the second embodiment, the same components as those of the connector 10 of the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. In addition, for description, the drawings described in Embodiment 1 are referred to.

[0094] Such as Figure 9A , Figure 9B , Figure 13A as well as Figure 14B As shown, the connector 10A of Embodiment 2 is composed of the following parts: a metal shell 62A, and a ring-shaped gasket 92 is attached to the outer peripheral side of the shell 62A; a housing 18...

Abstract

A connector is provided to suppress the malfunction of the sealing member. The connector (10) has: a cylindrical outer casing (62) having an opening portion (66) on one side; a casing (18) disposed inside the outer casing (62) and provided with at least one contact (12); and an annular sealing member (90) disposed between the outer casing (62) and the casing (18), and having a wall portion annularly on the opposite side of the opening portion (66) of the outer casing (62). The wall portion (72) is formed to extend inwardly so as to open a through hole (70) smaller than the opening portion (66), and the sealing member (90) is sandwiched between the wall portion (72) of the outer casing (62) and the housing (18).

Description

technical field [0001] The present invention relates to a connector having a waterproof function, and more specifically, to a connector that suppresses detachment, deformation, damage, and other defects of a waterproof sealing member. Background technique [0002] Conventionally, sealing members such as O-rings have been used to impart a waterproof function to connectors. For example, the following patent document 1 discloses an invention of a waterproof connector, which is characterized in that it has: a substantially cylindrical first housing formed of a conductive material and disposed on the plug insertion side; a cylindrical second casing, which is formed of a conductive material, and engaged with the first casing; an outer seal, which is provided around the outer periphery of the first casing, and is located outside the first casing; a support portion , which is installed in the rear part of the engaging body of the first housing and the second housing in a wall shape...
