Abstract

PURPOSE:To provide a connector capable of interrupting a circuit promptly upon abnormal heat generation to thereby prevent generation of accident by storing thermosensitive fuses and pin receptactles connected directly at a specified interval in a connector case. CONSTITUTION:A connector main body 6 is composed of a connector case 5, pin receptacles 4 and thermosensitive fuses 3 connected to the receptacles 4 directly at the interval of 3-20mm. The fuses 3 are connected to a wire insertion plug 1 through leads 2. The pin receptacles 4 are capable of being fitted to the pins 7 detachably and the pins 7 are, for example, connected to heat generation wires 9 inside an electric carpet 8. If abnormal heat is generated at the connection between the pin receptacles 4 and the pins 7, the fuses 3 shut out the circuit to prevent malfunction or burning accident from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a connector having a configuration that is effective for electrical equipment such as electric carpets, electric blankets, etc., which supply power through a connecting portion.

BACKGROUND OF THE INVENTION In recent years, electric carpets and the like have come to have connectors that allow the power cord and main body to be separated from each other for reasons of interior design and safety.

The general structure and usage state of a conventional connector of this type will be explained with reference to FIG. 2.

As shown in the figure, the connector body 6 is connected to the connector case 5.
and a pin receiver 4, and the pin receiver 4 is connected to a power supply plug 1 via a lead wire 2. Pin holder 4 is pin 7
The pin 7 is connected to the heating wire 9 in the electric carpet 8.

In the above configuration, when the pin receiver 4 and the pin 7 are connected and the power plug 1 is inserted into an outlet, the heating wire 9 generates heat.

Problems to be Solved by the Invention In such conventional connectors, electrical connection is made by contact between conductive materials such as pin receiver 4 and pin 7, and when contact resistance increases or overcurrent flows, , there was a risk of abnormal heat generation at the contact area, leading to loss of function or burnout.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a connector that can prevent accidents by interrupting the circuit when abnormal heat generation occurs.

Means for Solving the Problems In order to achieve the above object, the present invention is comprised of a temperature fuse and a pin receiver that are directly connected and housed within a connector case at a distance of 3 to 20 mm.

Here, the reason for limiting the number of alternate layers from 3 to 20 will be explained.

First, if you try to connect the temperature fuse directly to the pin holder by making the distance shorter than 3.2, excessive force or heat will be applied to the temperature fuse, which may damage the temperature fuse. Also, 2
If the distance is longer than zero, the temperature fuse will not be able to quickly detect abnormal heat generation at the contact area between the pin holder and the bottle, and there is a risk of loss of function or burnout.

Function The present invention has the above-described configuration, and the temperature fuse and the pin holder or bottle are directly connected at a distance of 3 to 20 m, so if abnormal heat is generated at the contact between the pin holder and the bottle, the temperature fuse will interrupt the circuit. This can prevent accidents from occurring.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

As shown in the figure, the connector body 6 is connected to the connector case 5.
A temperature fuse 3 is directly connected to a pin receiver 4 at a distance of 10++ m, and the temperature fuse 3 is connected to an electric wire plug 1 via a lead wire 2. The pin receiver 4 is detachably connected to the pin 7, and the pin 7 is connected to a heating wire 9 in the electric carpet 8.

To explain the operation in the above configuration, the current supplied from the power plug 1 flows through the lead wire 2 to the temperature fuse 3 and the pin holder 4, and then flows to the bottle 7 with the pin holder 4 and the bottle 7 connected. , generates heat 18. At this time, if abnormal heat is generated at the contact portion between the pin receiver 4 and the bottle 7, the temperature fuse 3 interrupts the circuit.

In this way, according to the connector of the embodiment of the present invention, the temperature fuse 3 is directly connected to the pin receiver 4 at a distance of 10 mm, so if abnormal heat is generated at the contact portion between the pin receiver 4 and the bottle 7, the temperature fuse can be quickly removed. 8 can interrupt the circuit and prevent loss of function and burnout accidents.

In addition, as shown in FIG. 3, the bin side connector case 10
The same can be said of a connector in which the bottle 7 and the temperature fuse 3 are directly connected and housed at a distance of 3 to 20 companies.

Effects of the Invention As is clear from the above embodiments, according to the present invention, since the temperature fuse is directly connected to the pin holder or bottle at a distance of 3 to 20 mm, abnormal heat generation occurs at the contact area between the pin holder and the bottle. In such a case, a temperature fuse can quickly cut off the circuit, thereby providing a connector that can prevent loss of function or burnout.
