JPH0471173A - Method of connecting connector terminal with cable - Google Patents

Abstract

PURPOSE:To equip a joint part with fatigue resistance against iterative temp. variations and external force applications and enhance the reliability by holding a cable with plastic deformation of a holder part, and securing the cable to the holder part using a solder paste applied previously to the inner wall of the holder part. CONSTITUTION:A U-form holder part 1 is provided which is deformable plastically to a connector terminal. A solder paste 2 is applied previously to the inner wall of this holder part 1. In the condition that one end of a cable 3 is inserted in the holder part 1, the open end of the holder part 1 is deformed plastically, and holding is made with the holder part 1 while cable end is in pressure contact with the open end. The holder part 1 is heated for a certain period of time from the outside by a heating means, for ex. soldering iron 4, to melt the soldering paste 2, and thereby the cable end is secured to the holder part 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for connecting terminals of a connector and one end of a cable.

[Conventional technology] Conventionally, as a method for connecting connector terminals and cables,
As shown in FIG. 4, a cylinder 101 is formed in the connector terminal, the upper end of this cylinder 101 is cut out, one end of the cable 102 is inserted into the cylinder 101, and solder is applied from the notch hole 101a of the cylinder 101. A method is known in which a cable 102 is soldered to a cylinder 101 by pouring it into the cylinder.

Moreover, as shown in FIG. 5, as a conventional method for connecting a connector terminal and a cable, a U-shaped holding part 103 that can be plastically deformed is formed on the connector terminal, and this holding part 103 is It is known that the opening end of the holding part 103 is plastically deformed while the one end of the cable 102 is inserted, so that the one end of the cable 102 is held by the holding part 103.

[Problem to be solved by the invention] However, in the former case, the reliability of the connection depends on the characteristics of the soldering, so the connection part becomes fatigued and destroyed by repeated temperature changes and external forces, resulting in electrical failure. The problem is that it is easy to do.

Also, in the latter case, there is a finding that it is difficult to coordinate to maintain a reliable connection when the cable is a single wire.

An object of the present invention is to provide connector terminals and cables that are easy to adjust to maintain a reliable connection even when the cable is a single wire. The purpose is to provide a connection method.

[Means for Solving the Problems] According to the present invention, a U-shaped holding portion that can be plastically deformed is formed on a connector terminal, and solder paste is applied to the inner wall of this holding portion in advance, and the With one end of the cable inserted into the holding part, the open end of the holding part is plastically deformed and the one end of the cable is held in pressure contact with the holding part, and this holding part is connected to a heating device from the outside. There is obtained a method for connecting a connector terminal and a cable, characterized in that the solder paste is melted by heating, thereby fixing one end of the cable to the holding part.

[Example] Next, embodiments of the present invention will be described in detail based on the drawings.

First, as shown in FIG. 1(a), a U-shaped holding portion 1 that can be plastically deformed is formed on a connector terminal. Next, as shown in FIG. 1(b), solder paste 2 is applied to the inner wall of the holding part 1 in advance.

Next, as shown in FIGS. 1(c) and 2, with one end of the cable 3 inserted into the holding part 1,
The open end of the cable 3 is plastically deformed and one end of the cable 3 is held in pressure contact with the holding part 1 as shown in FIG. 1 (<1) and FIG. 3.

Next, as shown in FIG. 1(e), the holding part 1 is heated from the outside with a heating device such as a heating device 4 for a predetermined period of time to melt the solder paste 2 and thereby the cable 3
One end of the is fixed to the holding part 1.

[Effects of the Invention] According to the present invention, the cable is held by plastic deformation of the holding part, and the cable is fixed to the holding part by the solder paste applied to the inner wall of the holding part in advance, so that the connection part does not have to be repeatedly connected. Less prone to fatigue due to temperature changes and external forces
< and is easy to adjust to maintain a reliable connection even when the cable is a single wire.
