Embodiment 1

[0042] Such as figure 1 , figure 2 As shown, the vehicle power relay component 1 of this example has a terminal part 3, a molded resin part 5, and a sealing part 7, the terminal part 3 is connected to the conductor 20 of the electric wire 2, and the molded resin part 5 covers at least the terminal In the electrical connection portion 4 between the component 3 and the conductor 20 , the sealing portion 7 seals a gap formed between the terminal component 3 and the molded resin portion 5 . In this example, the terminal part 3 has a conductor crimping part 31 that crimps the conductor 20 of the electric wire 2 and an insulator crimping part 32 that crimps the insulator 21 of the electric wire 2 . In addition, in this example, the connection part 33 of the terminal part 3 connected to the target terminal part (not shown) protrudes from the molded resin part 5, and the part of the terminal part 3 closer to the electrical connection part 4 than the connection part 33 is buried. In...

Embodiment 2

[0048] Such as Figure 3 ~ Figure 5 As shown, the vehicle power relay unit 1 of this example has a bus bar 81, a housing 82, and a sealing portion 7. The housing 82 has a molded resin portion 820 for fixing the bus bar 81, and the sealing portion 7 seals the bus bar 81 and the mold. The gap 83 between the resin parts 820 is plasticized. In the vehicle power relay component 1 of this example, the bus bar 81 is specifically configured to integrally include an embedded portion 810 embedded in a molded resin portion 820 and a connecting portion 811 protruding outward from the molded resin portion 820 . The sealing portion 7 seals the gap 83 existing between the embedded portion 810 and the molded resin portion 820 .

[0049] The molded resin portion 820 in the housing 82 is formed of thermoplastic resin in this example. Specifically, the thermoplastic resin is an aromatic polyamide resin (aromatic nylon resin) reinforced with glass fibers. Specifically, the molded resin part 82...

Abstract

A seal member for a vehicle that is capable of suppressing a decrease in the adhesive strength and the fluidization of the adhesive and maintaining high sealing property even in the case where the seal member is exposed to a heat reception environment and an oil environment, and an electric relay component for a vehicle using this seal member are provided. The seal member is constituted by a crosslinked adhesive composition containing an unvulcanized acrylic rubber having at least one functional group out of an epoxy group and a carboxy group and a vulcanizing agent capable of reacting with the functional group so as to form a crosslinking point. Preferably, the adhesive composition further contains a silane coupling agent. An electric relay component (1) for a vehicle has a seal portion (7) constituted by the seal member.

Description

technical field [0001] The present invention relates to a vehicle sealing member and a vehicle power relay component. Background technique [0002] Conventionally, adhesives have been used as sealing members in order to ensure liquid repellency against liquids such as oil and water in vehicle electrical relay parts. [0003] For example, there is known an electrical relay component for a vehicle that includes a terminal component connected to a conductor of an electric wire, and a molded resin portion that covers an electrical connection between the terminal component and the conductor. Usually, the molded resin portion is difficult to adhere to metal terminal parts, and dimensional changes due to molding shrinkage or the like are likely to occur. Therefore, in order to seal the unavoidable gap formed between the terminal component and the molded resin portion, a sealing member is often provided in the gap portion (see Patent Document 1, etc.). As the sealing member, speci...
