Description

[Detailed Description of the Invention] "Purpose" (Industrial Field of Application) This invention relates to a high voltage connector with a built-in fixed resistor, and more particularly, to a high voltage connector with a built-in fixed resistor for a power cord of a copying machine or the like.

(Prior Art) For example, a high voltage of tens of thousands of volts is applied to a power cord connector of a copying machine, so it must be manufactured to be robust. In order to protect the copying machine body and the high voltage connector of the power cord, it is conceivable to incorporate a fixed resistor connected to the power cord line into the connector and mold it integrally.

(Problem to be solved by the invention) When a power supply lead wire is connected by soldering to a fixed resistor installed in a high voltage connector and guided into a molding die to injection mold the connector, the required The insulating molten synthetic resin of
Kg/1cm ² ), fixed resistors are affected by heat and pressure, and the resistance value changes or decreases due to molding heat and molding pressure, making it impossible to obtain the resistance value required by safety standards. The connector may become unusable or the copying machine may be adversely affected.

Furthermore, the high voltage lead wire soldered to the pole needle of the fixed resistor may come off due to molding pressure, or may cause poor contact or short circuit during long-term use.

This invention aims to eliminate the above-mentioned drawbacks, and its gist is that it consists of a conductive body with a threaded part around its periphery, also made of a conductive material, and is integrated with the body and has a slot formed on its upper surface. , an electrode sleeve having a head with a horizontal through hole bored at its lower center; a coil spring type electrode terminal engaged with the threaded part of the electrode sleeve; slightly longer than the horizontal through hole; a hollow insulating casing penetrated into the through hole and partially protruding from the periphery of the head; fitted into the insulating casing, and one pole needle fitted into the slot and soldered; This is a high voltage connector with a built-in fixed resistor, in which the other pole needle is soldered to a high voltage lead wire and is integrally molded into the connector main body.

"Structure" An embodiment of the high voltage connector according to the invention shown in the drawings will be described. In FIGS. 2 to 5, the electrode sleeve 10 is made of a conductive material and consists of a main body 12 with a threaded part 12a around the periphery, and a head 14 formed integrally with the main body and on the upper part thereof. A slot 16 is formed on the upper surface of the head, and a horizontal through hole 18 is bored at the center of the lower part.

A hollow insulating casing 20 that is slightly longer than the horizontal through hole 18 of the head 14 and a fixed resistor 24 fitted therein is passed through the through hole, and both ends of the casing partially protrude around the head. Then, one of the pole needles 24a is fitted into the slot 16 and soldered,
The other pole needle 24b is soldered to one end of a required high voltage lead wire 26.

The upper half 22a of a threaded sleeve type electrode terminal 22 having a diameter corresponding to the threaded groove is rotatably screwed onto the equal portion 12a of the main body 12, and the lower half 22b projects downward from the threaded portion 12a. let

In this way, the hollow insulating casing 20 containing the fixed resistor 24, the electrode sleeve 10, the coil
The spring-type electrode terminal 22 and a portion of the high voltage lead wire 26 are fitted together into a required molding die (not shown), and an insulating molten synthetic resin is injected, cured, and removed from the mold, as shown in FIG. A high voltage connector with a built-in fixed resistor as shown in the figure is obtained. The slave coil spring type electrode terminal 22 is on the top and the head 14 is on the bottom.

"Operations and Effects" In the high voltage connector 2 with a built-in fixed resistor having the above-described configuration, the fixed resistor 24 fitted in the hollow insulating casing 20 is attached to the electrode sleeve 10.
Since the insulating casing partially protrudes from the periphery of the head, it will not cause a short circuit, and the resistor will not be adversely affected by molding heat or molding pressure. The pole needle 24a is the head 14
Since it is fitted into the slot 16 and soldered, it does not come off from the head and is stable. Therefore, the electrode sleeve 10 is securely fixed mechanically and electrically within the high voltage collector 2, and even if an abnormal voltage is applied, the fixed resistor protects the required equipment, and the required electrical equipment can be protected without contact failure or short circuit. This makes it possible to supply stable power to the
