Problems solved by technology

[0003] Here, in the electrical connector in which the shell and the connecting piece are integrally formed, the shell and the connecting piece are not in close contact, and a gap is formed between the shell and the connecting piece, and the desired waterproof effect cannot be obtained.
On the other hand, the electrical connector that integrally molds the connector with the thin groove on the surface and the housing can obtain the desired waterproof effect, but it is necessary to process the connector, so the product and manufacturing costs will increase

[0067] (Construction of electrical connector)

[0068] Regarding the structure of the electrical connector 1 according to the first embodiment of the present invention, while referring to Figure 1 ~ Figure 3 It will be described in detail below.

[0069] The electrical connector 1 of the present embodiment includes a housing 10 , a connector 20 , a front housing member 30 , a rear housing member 40 , an external waterproof member 50 , and a shielding plate 60 .

[0070] The case 10 is formed of an insulating material, and holds the connector 20 . The housing 10 contains a silane coupling agent along the outer peripheral surface of the connector 20 and in close contact with the connector 20 . The housing 10 does not contain a silane coupling agent at the rear end portion where the connector 20 protrudes rearward. Here, the silane coupling agent has a reactive group that can chemically combine with an inorganic material and a reactive group that can chemically combine with a...

Abstract

An electrical connector and a method for manufacturing the electrical connector are provided to make the electrical connector watertight, simplify assembly, and suppress an increase in manufacturing cost. The electrical connector (1) includes an insulating housing (10), and conductive contacts (10a) and connection members (20b) held by the housing. The conductive contacts including connection portions (21a) that are exposed on a front side of the housing (10) and connect to mating contacts of a mating connector, and terminal portions (22a) that protrude behind the housing (10). A portion of the housing (10) in close contact with the contacts (20) along the outer peripheries of the contacts (20) contains a silane coupling agent.

Description

technical field [0001] The invention relates to an electrical connector with waterproof function and a manufacturing method of the electrical connector. Background technique [0002] Conventionally, electrical connectors mounted on electronic equipment have been required to provide a waterproof function for externally waterproofing the inside of the electronic equipment. The electrical connector has a mating portion for mating with a mating connector and is exposed to the outside of the housing of the electronic device, a conductive connector disposed on the mating portion, and an insulating connector that maintains the connector. The gap between the shells must be waterproof. [0003] Here, in the electrical connector in which the shell and the connecting piece are integrally formed, the shell and the connecting piece are not in close contact, and a gap is formed between the shell and the connecting piece, and the desired waterproof effect cannot be obtained. On the other...
