Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a bulb socket installed in an automobile lamp.

<Conventional technology> When attaching an automotive bulb socket to a light fixture, the bulb socket is inserted into the bulb mounting opening of the light fixture and rotated approximately 60° to 90° to install it, but with conventional bulb sockets, the bulb socket is rotated. There was no special knurling for the bulb, and even if there was one, it was shaped like a single letter on the left and right, making it difficult to rotate the bulb socket and making it difficult to attach it to the lamp.

<Problems to be solved by the invention> The present invention has been developed in view of the above-mentioned problems in the past, and it is designed to be easy and accurate to attach to the lamp, and has a high rigidity and robustness of the socket body. Moreover, it is an object of the present invention to provide a valve socket for an automobile which can also protect the cord led out from the cord insertion hole.

<Means for Solving the Problems> The automotive valve socket of the present invention, which achieves the above object, has four knob pieces protruding from the socket body arranged in a substantially cross shape around the cord insertion hole. The present invention is characterized in that two adjacent knob pieces of the individual knob pieces are connected to each other by a reinforcing wall protruding along the edge of the cord insertion hole.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The invented automotive valve socket is the same as the conventional one.
A socket member 2 that removably supports the valve 1
and a socket body 3 that integrally attaches and supports the socket member 2.
is formed into a cylindrical shape having a J-slot 4 using a metal plate, and an insulator 6 connected to a cord 5 is incorporated inside the cylinder.

The socket main body 3 includes a bottomed cylindrical mounting support portion 31 for mounting and supporting the socket member 2, and a protruding portion formed on the rim of the mounting support portion 31 to allow the socket main body 3 to be removably mounted on a bulb mounting opening of a lamp. a flange 32 and a bayonet 33, and a knob protruding from the outer periphery of the mounting support portion 31 to facilitate rotational operation of the socket main body 3 when mounting or removing the socket main body 3 from a bulb mounting opening of a lamp. The piece 34 is formed into the same body using a resin material.

The four knob pieces 34 are arranged along the outer periphery of the mounting support part 31 in the axial direction.
d are arranged in a substantially cross shape with the cord insertion hole 35 as the center and are formed to protrude. That is, 4 picking pieces 3
4a, 34b, 34c, and 34d are respectively formed to protrude from the rear surface of the flange 32 of the mounting support part 31 along the outer surface of the mounting support part 31 to a point sufficiently rearward of the cord insertion hole 35, and approximately centered around the cord insertion hole 35. They are arranged in a cross shape. And these four knob pieces 34a, 34b, 34
The two adjacent tabs c and 34d, in the illustrated embodiment, the tabs 34a and 34b, and 34c and 34d, are connected to the outside edge 35 of the cord insertion hole 35.
a in an arc shape and at the tips 34a', 3 of the knob pieces.
4b', 34c', and 34d' are also connected and integrated by reinforcing walls 36a and 36b formed protruding at the same height. Therefore, between the knob pieces 34a and 34d that are not connected by the reinforcing walls 36a and 36b, and between the knob pieces 3
Between 4b and 34c, valleys 38a and 38b are formed which are flush with the outer edge 35a of the cord insertion hole 35. Also, any one knob piece, in the case of the illustrated embodiment, the tip 34 of the knob piece 34b.
A mark protrusion 37, which serves as a mark when attaching and detaching the socket main body 3 to and from the bulb mounting opening of the lamp, is formed protruding from the same body at b'.

In this way, by providing a mark protrusion protruding from the tip of one of the four knob pieces, even if the bulb installation port of the light fixture is hidden by the vehicle body or the light fixture body, etc., the mark protrusion will remain visible. It becomes easy to know the location of the bulb socket by touching it with a fingertip, and it becomes possible to easily and accurately perform the work of attaching and detaching the bulb to the lamp.

In addition, 7 in the figure is the rubber button of code 5,
8 is a lead-out portion of the grounding cord 9.

<Effects of the invention> Since the automotive bulb socket of the present invention is constructed in this way, when attaching or removing the bulb from the bulb mounting opening of the lamp, the fingertips can easily catch on the knob, making it easier to rotate the bulb socket. It is possible to easily attach and detach the lamp to the lamp.

Moreover, since the adjacent knob pieces among the four knob pieces are connected and integrated through the reinforcing wall that abuts along the edge of the cord insertion hole, the strength of each knob piece is high. The socket body itself can be made highly rigid and robust, and the cord of the socket body can be drawn out from between the knob pieces (troughs 38a, 38b) that are not connected and integrated by the reinforcing wall. It is possible to protect the cord led out from the insertion hole, and at the same time, it is possible to secure the rear space of the socket body without putting strain on the cord.

Therefore, the intended purpose can be achieved.

[Brief explanation of the drawing]

The drawings show an example of the present invention, in which FIG. 1 is a perspective view, FIG. 2 is a rear view, and FIG. 3 is a sectional view taken along the line 3--3 in FIG. In the figure, 3 is the socket body, 34, 34a, 34
b, 34c, 34d are knob pieces, 35 is a cord insertion hole, 36a, 36b are reinforcing walls, 37 is a mark protrusion,
It is.
