Problems solved by technology

[0005] However, since the elongation of the resin filler with high-pressure durability of high-humidity durability or ATF durability is small in the prior art, there is concern about the terminal of the connector housing during the insert molding of the terminal part and the connector housing. Hold hole perimeter will crack or peel

[0103] 60 mm high x 60 mm wide x 2 mm defined in ASTM D732 by using syndiotactic polystyrene resin XAREC (registered trademark) S131 (material number R1) manufactured by Idemitsu Kosan Co., Ltd. Thick fiber-reinforced plastic panels. This fiber-reinforced plastic plate 28 was used as sample No. A-1. Figure 4 A schematic plan view of a fiber reinforced plastic plate 28 is shown. exist Figure 4 , the arrow OR indicates the direction in which the fibers are oriented in the fiber reinforced plastic, the reference sign M indicates the MD direction, and the reference sign TD indicates the TD direction. The direction OR in which the fibers are oriented in the fiber-reinforced plastic sheet 28 coincides with the MD direction.

[0104] Subsequently, tensile test pieces 29M and 29T of 20 mm width×60 mm length×2 mm thickness were cut out from the fiber-reinforced plastic plate 28 . Such as Figure 5 As shown, tensile test piece 29M is cut...

[0156] Except for using material No.R2 to R5 shown in Tables 1 to 3 instead of material No.R1, the fiber-reinforced plastic plate 28 was manufactured as in the of "1. Tensile strength" of Example 1 (test Sample No.A-2 to A-5). Sample Nos. A-2 to A-4 and A-5 are samples of Examples 2 to 4 and Comparative Example 1, respectively.

[0157] Subsequently, as in Example 1, tensile test pieces 29M and 29T of 20 mm wide x 60 mm long x 2 mm thick were cut out from the fiber-reinforced plastic plate 28 (sample Nos. A-2 to A-5).

Abstract

A liquid-proof connector includes a columnar terminal having a rectangular cross-sectional shape; and a connector that includes a connector housing which is obtained through insert molding with the columnar terminal, is made of fiber-reinforced plastic in which fibers are oriented in a longitudinal direction of the columnar terminal, and has a terminal holding hole to which the columnar terminal is inserted and a fitting portion which fits to a counterpart terminal. An in-holding-hole insertion portion which is a portion being present within the terminal holding hole of the columnar terminal is fixed to the terminal holding hole in an airtight state by bringing a surface in close contact with an inner surface of the terminal holding hole. Tensile strength of the fiber-reinforced plastic ina direction perpendicular to the longitudinal direction is 45 MPa or more.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2018-114470 filed on June 15, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a liquid-proof connector, and in particular, to a liquid-proof connector including a connector housing integrally formed with a columnar terminal by insert molding. Background technique [0004] Conventionally, there is known a liquid-proof connector in which a terminal portion and a connector housing are integrally formed by insert molding. In recent years, since liquid-proof connectors that withstand higher pressures are required, resin fillers used for such high-pressure liquid-proof connectors must have high-pressure durability. In many cases, resin fillers with high-pressure durability also need to have high-humidity durability or automatic transmission fluid (ATF)...
