CN-115699469-B - Rubber bolt unit and connector

Abstract

The rubber stopper units (10, 10A, 10B) are provided with terminals (13, 13A, 14A), an electric wire (11), and rubber stoppers (12, 12A, 12B) that are in close contact with the outer periphery of the electric wire (11). The electric wire (11) has a conduction portion (22) connected to the terminals (13, 13A, 14A). The rubber plugs (12, 12A, 12B) have holding portions (17) that are sandwiched between the terminals (13, 13A, 14A) and the electric wires (11). The conduction part (22) and the holding part (17) are arranged to overlap in the axial direction (X) of the wire (11).

Description

Rubber bolt unit and connector Technical Field The present disclosure relates to rubber plug units and connectors. Background The connector disclosed in patent document 1 includes a wire, a wire tube portion held by a terminal, and an insulating tube portion, and a rubber plug (sealing body) integrally provided with the wire and the terminal so as to cover the insulating tube portion. The connector disclosed in patent document 2 includes an electric wire connected to an electric wire connection portion of a connection terminal, and a rubber plug (sealing member) through which the electric wire is inserted. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2015-90843 Patent document 2 Japanese patent application laid-open No. 2017-216202 Disclosure of Invention Problems to be solved by the invention In the cases of patent document 1 and patent document 2, there is a possibility that the rubber plug is displaced in the axial direction with respect to the electric wire. In this case, the rubber plug may be held between the insulating tube portion of the terminal and the electric wire, and the displacement of the rubber plug with respect to the electric wire may be restricted. However, when the portion where the rubber plug is held by the insulating tube portion and the portion where the electric wire is connected by the wire tube portion are disposed in an axially aligned manner, there is a possibility that the unit including the rubber plug and the connector become large. Accordingly, the present disclosure aims to provide a rubber stopper unit and a connector that avoid enlargement. Means for solving the problems The rubber stopper unit of the present disclosure includes a terminal, an electric wire having a conductive portion connected to the terminal, and a rubber stopper closely attached to an outer periphery of the electric wire, the rubber stopper having a holding portion sandwiched between the terminal and the electric wire, the conductive portion and the holding portion being disposed so as to overlap in an axial direction of the electric wire. Effects of the invention According to the present disclosure, a rubber stopper unit that avoids enlargement can be provided.

Detailed Description [ Description of embodiments of the present disclosure ] First, embodiments of the present disclosure will be described. The rubber stopper unit of the present disclosure, (1) The electric wire has a conductive portion connected to the terminal, and the rubber plug has a holding portion sandwiched between the terminal and the electric wire, and the conductive portion and the holding portion are arranged so as to overlap in an axial direction of the electric wire. Thus, when the conduction portion and the holding portion are disposed so as to overlap each other in the axial direction of the electric wire, the rubber plug unit can be prevented from being enlarged in the axial direction. (2) Preferably, the electric wire is a single core wire. The single-core wire has rigidity for maintaining a certain shape, so that the state in which the conduction portion and the holding portion are overlapped can be maintained well. (3) Preferably, the conducting portion and the holding portion are arranged in a circumferential direction of the electric wire, and the terminal has a collective barrel portion that collectively surrounds the conducting portion and the holding portion. Accordingly, the overall cylindrical portion can have both the function of connecting to the electric wire (the function of the cylindrical portion) and the function of holding the rubber stopper (the function of the insulating cylindrical portion). As a result, the overall length of the terminal can be reduced in the axial direction as compared with a known terminal in which the wire tube portion and the insulating tube portion are arranged in the axial direction. (4) Preferably, a protrusion contacting the conduction portion is provided on an inner periphery of the collective cylinder portion. Accordingly, the terminal can be in good contact with the conductive portion via the protrusion. In addition, the connector of the present disclosure, (1) The connector housing is provided with the rubber plug unit and the cavity, wherein the electri
