Problems solved by technology

[0005] Figure 11 Since the waterproof connector 20 is insert-molded with the resin case 22 together with the terminal member 21, there are few structural constraints during assembly and the height can be reduced. Adherence between bodies 22 is unreliable under thermal changes (for example, thermal changes caused by brazing, etc.)

Embodiment Construction

[0037] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the same or equivalent constituent elements, members, processes, etc. shown in the drawings are given the same reference numerals, and overlapping descriptions are appropriately omitted. Furthermore, the embodiments are not intended to limit the invention but are examples, and all the features and combinations thereof described in the embodiments are not necessarily essential to the invention.

[0038] Such as Figure 1 to Figure 6 As shown, the waterproof connector 30 includes: an insulating housing 31 made of hard resin (plastic); an insulating elastic body 40 such as rubber held by the housing 31; The terminal pin (receiving pin) 50 of the conductor. It should be noted that, if figure 2 That defines the up and down directions.

[0039] The terminal pin 50 is a part that is in contact with the contact on the opposite side...

Abstract

By concentrating on the structure of the case and the elastic body, it is possible to secure a reliable waterproof structure and realize simplification and low height of the assembly process. It includes: an insulating case (31); an insulating elastic body (40) held by the case (31); and a terminal pin (50) penetrating through the elastic body (40) and held by the case (31). The elastic body (40) has: an outer elastic portion (41) and an inner elastic portion (42) divided by the housing (31); and a connecting portion (43) connecting the outer elastic portion (41) and the inner elastic portion (42) ), the housing (31) is provided with a wall portion (35) that the inner elastic portion (42) through which the terminal pin (50) penetrates contacts in a compressed state.

Description

technical field [0001] The present invention relates to a waterproof connector used as an I / O connector of notebook PCs, tablet terminals, wearable terminals, mobile phones and other information terminals, POS terminals and the like. Background technique [0002] 1 example of conventional waterproof connector Figure 10 shown. Figure 10 The waterproof connector 10 described above has a structure in which receiving pins (terminal pins) 3 are incorporated in a resin case 4 using an inner rubber 1 and an outer rubber 2 for watertight sealing. When describing the assembly sequence, first as Figure 10 Prepare the inner rubber 1, the outer rubber 2, the receiving pin 3, and the resin case 4 as in (A), insert the inner rubber 1 into the receiving pin 3 as shown in the figure (B), and insert them into the resin case 4 (the Figure (C)). And, if Figure 10 The outer rubber 2 is fitted into the resin case 4 as in (D). The watertight seal between the receiving pin 3 and the housing ...
