ピンプラグの製造法に係るものである。DETAILED DESCRIPTION OF THE INVENTION (I) ... Field of Industrial Application The present invention is for electrically connecting various electronic and electrical devices between devices, between devices and power supplies, and between cords. The present invention relates to a method of manufacturing a pin plug, which is a kind of connector used by being attached to the tip of a cord.

ンの、２種類のピンが用いられている。Conventionally, a pin plug is widely used in which a pin 1 connected to another polarity electric path is fixed in a spring sleeve 2 connected to one polarity electric path via an insulating member 3 attached to a terminal portion 1'of the pin 1. However, the pin 1 of the pin plug is formed by grinding a metal (copper alloy) airless material, that is, a so-called grounded airless pin, and a metal (plate) piece is drawn and provided. In addition, two types of pins, which are hollow pipe-shaped pins, are used.
本発明は、本発明に独自な構成に製した中空パイプ状の
ピンを用いたピンプラグの製造法である。The present invention is a method for manufacturing a pin plug using a hollow pipe-shaped pin having a unique structure to the present invention.

い。(II) ... Conventional technology and its problems Conventional hollow pipe-shaped pins are only formed in the shape shown in Fig. 5 for convenience of drawing (ease of processing), and the pins are made of a material. The cost and processing cost are low, and it has the advantage that it is suitable for molding and caulking and fixing the insulating member to the terminal portion, but on the other hand, the body portion 1b and the terminal portion 1'have the same diameter and are convex between them. Since the strip 1c is formed, when the insulating member 3 is provided on the terminal portion 1'by molding or caulking, the opening 10 at the lower end of the terminal portion 1'is inevitably large (in this respect, an empty pin). The terminal 1'is ground to a small diameter and a small hole 6 is formed in it. Therefore, as shown in FIG. 6, (1), the core wire 4 must be soldered to a part of the peripheral edge of the opening 10. It is difficult to work because the soldering area is extremely small To, uniform, strong, can not be precise soldering. Further, when there is air in the hollow pipe and soldering is performed so as to block the opening, there is no escape area for the air, so that the solder is not well attached by being pushed by the air that thermally expands.

部分を膨張変形する。(2) Since most of the opening 10 remains open even after soldering the core wire 4, the molten resin enters the hollow pipe when the post-process slack knob 9 is molded. As a result, the air in the pipe thermally expands and expands and deforms the unsolidified molded portion.
（３）、端子部１′が径が太いと、＋−極が近接してい

It has drawbacks such as great property.

The pin and the hollow pipe-shaped pin are used while the advantages of the pin are removed and the disadvantages are removed.

効果を奏し得る。(VI) ... Operation and effect (1) ... When the insulating member 3 is molded on the terminal portion 1'd, by crimping 11 part of the terminal portion, the crimped 11 portion is insulated after molding. It serves as a detent for the member 3 and fixes it, and also serves as a stopper at the tip of the core wire 4 to be inserted for soldering,
Further, the air in the hollow pipe such as the body portion 1b is blocked to prevent the air from thermally expanding during the soldering and hindering the soldering. Further, when the knob 9 is molded in the subsequent step, the injection molten resin is It is possible to obtain operational effects such as prevention of invasion into the hollow pipe.

It is also possible to insert the core wire 4 or the core wire 4 and the core wire coating 5 into the lower end portion of the terminal portion protruding from, and caulk the portion to crimp-connect the core wire and the like, which is more stable than soldering. There is an advantage that a crimping type crimping connection means, which is regarded as a simple adhesion means, can be adopted.
