Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a valve socket that has a strong valve holding force.

[Conventional technology]

FIG. 6 is a longitudinal sectional view showing a conventional example of a bulb socket, and FIG. 7 is a perspective view illustrating the fitting of a bulb and a light bulb terminal.

As shown in FIG. 7, lead wires 2 are provided on both sides of the base portion 1 of the valve B, and grooves 3 are cut in the lateral direction on both sides.

On the other hand, the socket 4 has a bottomed valve insertion hole 5.
is provided, and a light bulb terminal 6 is attached to the bottom wall of the bulb insertion hole 5.

Then, when the base part 1 of the bulb B is inserted into the light bulb terminal 6, the tip of the light bulb terminal 6 elastically expands to accept the insertion of the base part 1, and the groove 3
When the valve B is overlapped with the base part 1, the valve B is fitted into the groove 3, and the valve B is fitted into the base part 1 as shown in FIG.

[Problem that the invention attempts to solve]

However, the holding force of the bulb B of the bulb terminal 6 is small, and when the bulb socket is installed in something that generates vibrations, such as a vehicle, there is a risk that the bulb B will fall off from the bulb terminal 6 due to vibration.

The present invention aims to solve such problems.

[Means for solving problems]

In order to solve the above problem, the valve socket of the present invention is formed into a flat ring shape, with opposing long sides protruding inward with a large radius of curvature. a bulb holder having elasticity, the bottom wall being continuous with the opposing short side portions, and having a protrusion on the inner surface of the center of the long side portion that engages with a groove formed in the base portion for the valve; A light bulb terminal into which the base part of the bulb is fitted is installed, and a hole through which the bulb holder can be inserted through with elastic deformation is provided in the peripheral wall standing on the periphery of the bottom wall. and a socket formed with a fitting surface into which the outer surfaces of the short side portions that have returned to their original shapes fit.

[Effect]

To attach the bulb holder to the socket,
The bulb holder is elastically deformed and inserted from the outside of the peripheral wall of the socket into the socket through the hole.

The inserted valve holder elastically returns to its original shape, both short sides are fitted into the fitting surfaces, and the bulb holder is integrally assembled into the socket.

The bulb holder whose both short side portions are fitted onto the fitting surface can be deformed in a direction in which both long side portions approach or separate from each other using both short side portions as fulcrums.

When inserting a bulb into the socket's bulb terminal, the protrusion is pressed against the base of the bulb, both long sides of the bulb holder elastically deform to allow the bulb to pass, and the protrusion is pressed into the groove in the base of the bulb. When the bulb holder is bent, the elastic force of both long sides of the bulb holder causes the protrusion to fit into the groove of the base portion and clamp the bulb.

Therefore, even if the bulb socket is placed in a vibrating environment, the insufficient clamping force of the bulb terminal is compensated for by the clamping force of the bulb holder, and the bulb is prevented from falling off.

To remove the valve from the socket, apply a withdrawal force to the valve.

When the valve is moved in the removal direction, the protrusion fitted into the groove is pushed out of the groove, the gap between both long sides is expanded, and the valve is removed as it is.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a valve socket, FIG. 2 is a partially cutaway plan view of a valve holder fitted into the socket, and FIG. 3 is a partially cutaway plan view of a valve holder fitted into the socket. 1 shows a longitudinal sectional view of a valve socket with a valve attached thereto.

The socket 4 has a peripheral wall 4b erected on the periphery of a substantially circular bottom wall 4a, and as in the conventional example, the peripheral wall 4b
A hole 5 with a bottom is formed inside the lamp, and a light bulb terminal 6 is provided on the bottom wall 4a.

However, in the present invention, holes 9 are provided at opposing positions on the inner surface of the peripheral wall 4b, and have a size that allows the valve holder 7, which will be described later, to be inserted into it when it is elastically deformed into an elongated shape. A concave fitting surface that becomes wider toward the inner surface is formed (fifth
(see figure).

The bulb holder 7 is detachably attached to the socket 4 and is made of an elastic material.
As shown in the figure, it is formed into a flat ring shape, with opposing long side portions 7a, 7a protruding inward with a large radius of curvature, and both long side portions 7a,
The end portion of 7a is continuous with the opposing short side portion 7b.

A projection 8 that engages with a groove 3 formed in the base portion 1 of the bulb B is provided on the inner surface of the central portion of the long side portion 7a.

Next, the operation of the valve socket constructed as above will be explained.

To attach the bulb holder 7 to the socket 4, the bulb holder 7 is elastically deformed into a flat shape and inserted into the interior of the socket 4 through the hole 9 from the outside of the peripheral wall 4b of the socket 4.

The bulb holder 7 elastically returns to its old shape inside the socket 4, and both short side portions 7b, 7b fit into the fitting surfaces of the holes 9, so that the bulb holder 7 is integrally assembled into the socket 4.

The assembled bulb holder 7 can be deformed using the short side portions 7b, 7b as fulcrums in a direction in which both the long side portions 7a, 7a approach or separate from each other.

To attach bulb B to the bulb socket assembled as described above, insert the base part 1 of bulb B into the bulb terminal 6 through the bulb holder 7.
Just plug it in.

When inserting the base part 1 into the bulb holder 7, the protrusion 8 is pushed by the base part 1, and both long side parts 7
a, 7a are elastically deformed to allow valve B to pass through.

When the projection 8 overlaps the groove 3 of the base portion 1, the projection 8 fits into the groove 3 of the base portion 1 due to the elastic force of both long side portions 7a, 7a, and the valve B is held therebetween.

Therefore, even if the bulb socket is placed in a vibrating environment, the insufficient clamping force of the bulb terminal 6 is compensated for by the clamping force of the bulb holder 7, and the bulb B is prevented from falling off.

To remove valve B from socket 4, a pulling force may be applied to valve B.

When the valve B moves in the removal direction, the protrusion 8 fitted into the groove 3 is pushed out from the groove, and the valve B is removed as it is.

[Effect of idea]

The present invention is configured as described above and has the following advantages:

(1) The bulb holder is formed into a roughly rectangular ring shape and has elasticity, so when it is inserted into the hole provided in the peripheral wall of the socket, it will elastically return within the socket and the short side will align with the fitting surface of the hole. It is fitted.

Therefore, the valve holder can be easily installed,
Or it can be removed.

(2) Since the valve holder fitted into the socket clamps the valve, it compensates for the lack of conventional valve holding force and prevents the valve from falling off even in environments that generate vibrations.

Therefore, the reliability of the electrical contact between the socket and the valve is improved.

(3) When a pulling force is applied to the valve, the long side portion of the bulb holder tends to be elastically deformed, so the protrusion is pushed out of the groove and the bulb is pulled out, making it easy to remove the bulb.

(4) It is convenient for maintenance because only the valve holder can be replaced.
