electrical connector

Abstract

PROBLEM TO BE SOLVED: To provide a small-sized electric connector which can endure a strong routing load of an electric wire and has high reliability. SOLUTION: An electric connector 10 comprises a body housing 11 which has a contact terminal installing portion 17 in which a plurality of contact terminals 42 including a signal terminal and a power source terminal is installed at an inner opening, and a holding portion 18 of an electric wire 40 connected to the plurality of the contact terminals 42; and a cover housing 30 which covers the contact terminal installing portion 17 and the holding portion 18 of the electric wire 40, and is attached to the body housing 11 while leading out the electric wire 40 to the outside. The body housing 11 is formed with a binding tool holding portion 20 in which a binding tool 44 for binding the electric wire 40 is fitted, and a fastener holding portion 21 for integrally fastening the electric wire 40 and the body housing 11 by a fastener 45, at the holding portion 18 of the electric wire 40.

Description

technical field [0001] The present invention relates to an electrical connector that suppresses the pulling load of electric wires, and more specifically, to an electrical connector including a binding member for binding electric wires and a fastener for integrally fastening the electric wires and a main body case. Background technique [0002] In a connector in which electric wires are drawn out in a lateral direction offset by 90° from the plugging and unplugging direction of the connector, when tensile stress is applied to the electric wires, the tensile stress is directly transmitted to the connector terminals. When the tensile stress increases, there are disadvantages in that the connection between the connector terminal and the electric wire is disconnected, the part called the lance (lance) where the connector terminal is assembled in the housing is deformed, and the connection between the connector terminal and the electric wire is deformed. The fit between the housi...

Problems solved by technology

[0010] However, in the electrical connector with the wire holding mechanism shown in the above-mentioned patent document 3, there is the following problem: since the wire binding member is accommodated in the space whose width is the same as the width of the part where the plug and the socket are fitted, it is necessary to Enlarging the external dimensions in the axial direction where mating is performed, resulting in an increase in the size of the electrical connector itself

In addition, there is also the following problem: Since the wire pulling load during use is directly applied to the cover, there is a possibility of damage, etc., thereby losing reliability. In order to compensate for these defects and ensure the strength of the cover, it is necessary to More locking parts (5 in the content described in the above-mentioned Patent Document 3) that are locked with the plug body are formed, which leads to an increase in manufacturing cost
