Description

[Detailed explanation of the invention] This invention enables a separately made lug terminal to be correctly positioned and securely and firmly attached to the outer periphery of the outer sleeve, which is the outer pole of a connecting device for low electrical power. This invention relates to an improvement of a lug terminal attachment device for light electrical equipment.

An example will be described in detail based on the drawings. Reference numeral 1 denotes a body of a connecting device A for low electrical power.

As shown in FIG. 2, this body 1 is in a state in which a core frame 11, which serves as an inner terminal, is extended from a tip pin 10, and the core frame 11 is positioned in advance so as to pass through the center portion of an outer cylinder sleeve 12, which serves as an outer pole. The chip pins 10 and the outer cylinder sleeve 12 are set in a mold (not shown), and a synthetic resin material serving as an insulator is poured so that an insulator 13 is interposed between the chip pins 10 and the outer cylinder sleeve 12. The insulator 13a at the tail end of the body 41 (right side in FIG. 1) is integrally formed with a protrusion 14 projecting toward the outer circumference.

Reference numeral 2 denotes a lug terminal which becomes an outer terminal when assembled to the outer peripheral surface of the outer sleeve 12 of the body 1.

This lug terminal 2 has a lug piece 23 extended from a mounting part 22 having a cylindrical cut 21 that fits into the outer peripheral surface of the outer sleeve 12, and a cord 3 connected to the extended end of the lug piece 23 as shown in FIG. The cord wires 31 and 32 are connected to the core frame 11 and the lug piece 2, which become the inner terminals.
A pair of opposing holding pieces 24.2 that hold the terminal of the above-mentioned cord 3 when soldering it to 3 and insert molding 4.
4, and furthermore, at the base end of the lug piece 23,
A cutout window 25 that fits into the protrusion 14 at the tail end of the body 1
This is a configuration with .

Note that the cutout window 25 is formed by extending the mounting portion 22 until it touches the insulator 13 as shown by the chain line in FIG.
In some cases, a cutout window 25 is formed in 2a.

Reference numeral 5 denotes a cylindrical ring for tightening the mounting portion 22 which is inserted into the outer cylinder sleeve 12 with the protrusion 14 and notch 25 fitted together, and its inner diameter is slightly larger than the outer diameter of the mounting portion 22. The diameter of the ring 5 is reduced and the ring 5 is forcibly attached to the mounting portion 22.
It is designed to be tightened by inserting it into the

Note that this ring 5 may also be used by carving a screw 51 on the outer periphery of the ring 5 as shown in FIG. 5, and screwing a body 52 onto the screw 51 as shown in FIG. 6 instead of insert molding. be.

Next, to explain the function and effect, the lug terminal 2 mounting device of this invention has a cylindrical mounting device with a cut 21 that is fitted into the outer periphery of the outer sleeve 12 which becomes the outer pole of the connecting device A for light electrical power. part 22 and the lug piece 23 extending from the attachment part 22, and the cylindrical attachment part 22 or the lug piece 2.
3, the lug terminal 2 is provided with a cutout window 25 formed to fit with the protrusion 14 protruding in the outer circumferential direction from the tail end of the body 41 of the connecting device A. Since the ring 5 is fitted onto the outer periphery of the cylindrical mounting portion 22 of the lug terminal 2 and tightened, the mounting portion 22 of the lug terminal 2 can be reliably positioned on the outer periphery of the outer cylindrical sleeve 12. It will be possible to install it firmly.
