Description

[Detailed Description of the Invention] The present invention relates to a socket dedicated to car accessories, which is provided on a tarash board of an automobile to connect car accessories such as an electric shaver.

Cars are powered by batteries, so car accessories such as electric razors, cleaners, and lighting stands are all powered by 12V or 24V DC power, and most of the power supplies are It is obtained from the cigarette lighter socket installed in most automobiles.

However, since cigarette lighter sockets were originally developed exclusively for cigarette lighters, they have a special structure such as a bimetal inside the socket that is unnecessary for other car accessories. In addition to being inconvenient for connecting to car accessories, the bimetal may be damaged, making it unsuitable for use as a power source for car accessories other than cigarette lighters.

The purpose of this invention is to solve these problems and provide a dedicated socket for car accessories that is suitable for connecting car accessories other than cigarette lighters and that can be easily assembled to the mounting panel. It has a flange on one end, a projection to prevent rotation and an elastic piece to prevent removal on the outer circumferential surface, and is made of synthetic resin and is inserted into the mounting hole of the mounting panel. Consists of a cylindrical mounting sleeve and a metal cylindrical body that forms a collar at one end and has a positive terminal and a ground terminal attached to the other end, respectively, and is inserted into the sleeve. In addition, the positive terminal and the earth terminal each have a plug blade, and each plug blade is provided to protrude from the back surface of the body in parallel to the axial direction of the body to enable connector connection.

With this structure, the bimetal will not get in the way when inserting connection plugs for car accessories other than cigarette lighters, and there will be no damage to the bimetal when attaching or removing the connection plug. In addition, the structure is simple, and the assembly to the mounting panel can be done from the front side of the mounting panel.Furthermore, the lead wires can be connected by connecting a connector with lead wires prepared in advance. The installation work is easy and the required man-hours can be shortened.

Next, one embodiment of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a cylindrical mounting sleeve made of an insulating synthetic leather resin molded product, with a flange 2 formed at one end, and a protrusion 3 for preventing rotation in the longitudinal direction on the outer circumferential surface. At the same time, two elastic pieces 4 for preventing removal are also provided.

This elastic piece 4 is formed by providing a U-shaped notch 5, and has a slope 6 protruding from the outer peripheral surface.
When inserting the mounting sleeve 1 into the mounting hole 8 of the mounting panel 7 of a dash board or the like, the elastic piece 4 is pushed inward and lowered, returns to its original position at a predetermined position, and the tip locks onto the back surface of the mounting panel 7. It acts as a stopper.

Note that the mounting hole 8 is circular and has a cutout 9 corresponding to the protrusion 3 at its lower part.

Reference numeral 11 denotes a metal cylindrical body, one end of which is folded back to form a collar 12, and a positive terminal 13 and a ground terminal 14 are attached to the bottom of the other end.

Each terminal 13.14 has a respective base 13a, 1
4a together with the insulating stand 15 and the insulating base 16
The positive terminal 13 contacts the terminal fitting 17 on the outer surface of the insulating base 16, and the terminal fitting 17 is placed at the bottom of the insulating base 16. The ground terminal 14 is sandwiched between the podium 11 and the insulating base 16 and
1 and is fixed.

Each terminal 13.14 also has a base 13a. It has plug blades 13b and 14b formed by bending at right angles to 14a, and protrudes in parallel with the guide protrusion 16a of the insulating base 16 in the axial direction of the tenon 11.

This pod 11 is inserted into the mounting sleeve 1 inserted into the mounting panel 7. Predetermined lead wires 18 and 19 are wired in advance, and the connector 20 is passed through the inside of the mounting sleeve 1 and inserted into the mounting panel. 1 from the back side toward you, and remove the plug blades 13b and 14 of each terminal 13 and 14.
After it is inserted into the mounting sleeve 1, it is inserted into the mounting sleeve 1 and fixed.

When inserted, the small protrusion 2 provided on the inner surface of the mounting sleeve 1 is inserted into the fixing hole 25 provided in the body of the podium 11.
'6 are fitted and positioned.

Reference numeral 29 denotes a disc-shaped lid, which is rotatably attached to the bearing portion 2a of the flange 2 with a pin 30, and is attached to a projection 31 of the shaft attachment portion.
By the action of the annular leaf spring 32, the opening 33 is held in either a closed state covering the opening 33 or an open state shown by chain lines in FIG.

The annular plate spring 32 is interposed between the flange 2 and the mounting panel 7 so that an operating portion 34 formed by partially convexing comes into contact with the protrusion 31 of the lid 29.

The socket of this embodiment is constructed as described above, and the terminal metal fitting 17 connected to the positive terminal 13 is exposed as a positive electrode at the center of the back of the Pod 11, and the earth terminal 14 is connected to the Pod 11. Since the electrode is a negative electrode, by using a plug having a structure suitable for this electrode arrangement as a connection plug for car accessories, it becomes possible to use the car accessories.

Furthermore, since there is no bimetal inside the POD 11 and it has a simple cylindrical shape, the shape of the connection plug inserted therein can be simple and easy to manufacture.

The lid 29 improves the appearance of the car accessory when it is not in use, and also prevents foreign matter such as dirt from entering the podium and exposing the live parts.

As is clear from the embodiments described above, the present invention consists of a mounting sleeve that is inserted into the mounting panel and a podium that is inserted into this mounting sleeve. Assembling the mounting sleeve and tenon to the mounting panel can be done only from the front side of the panel, making the work easy, and the elastic pieces and protrusions ensure secure installation. The structure is simple, and since there is no bimetal inside the POD, there is no possibility of the bimetal getting in the way or damaging the bimetal, and wiring to the POD can be done by inserting a pre-wired connector. Therefore, from this point of view as well, there is an advantage that the assembly work is simplified and the required man-hours can be shortened.
