Description

[Detailed Description of the Invention] A. Purpose of the Invention (1) Field of Industrial Use The present invention relates to a valve having an insertion portion protruding from one end of the valve body, and the valve body at the mounting position of the valve body. The present invention relates to a valve / socket assembly including a socket that engages with one end and a socket that has an insertion hole into which an insertion portion is inserted.

(2) Conventional Technology In such an assembly, it has been conventionally known that the fitting portion of the valve and the socket is provided with a concavo-convex portion that elastically engages with each other in order to ensure the mounting of the valve in the socket. (See, for example, Japanese Utility Model Publication No. 58-13583).

(3) Problems to be Solved by the Invention In the conventional assembly, the load of mounting the valve on the socket is light and the load of detaching the valve is heavy. For this reason, there is a problem that it is difficult to remove the valve from the socket due to a lack of moderation at the time of mounting and the fact that the fingertip that took the valve easily slips at the time of detaching.

The present invention has been made in view of such circumstances, and a great sense of moderation can be obtained when the valve is mounted by the cooperation of the elastic clamping piece specially provided in the socket and the locking projection specially provided in the valve insertion portion. When the valve is detached, it can be easily removed, and the clamping piece and the locking projection are made independent from the insertion point and the electrical contact point between the insertion holes so that the contact point fails. An object of the present invention is to provide the valve / socket assembly which can avoid and stably support the valve.

B. Configuration of the Invention (1) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a valve having an insertion portion protruding from one end of a valve body and a mounting position of the valve. A socket having a receiving hole that engages with one end of the valve body and an insertion hole into which the insertion portion is inserted, and with the insertion portion inserted into the insertion hole, the inside of the insertion hole A valve in which the socket side terminal exposed on the side surface and the valve side terminal exposed on the side surface of the insertion portion are in contact with each other.
In the socket assembly, the socket is provided with an elastic clamping piece that protrudes toward the side surface of the insertion part, separated from the insertion hole and the socket-side terminal, while it is attached to the side surface of the insertion part from the front of the valve installation position. By providing a locking projection that directly engages the nipping piece over the position and gives it an opening / closing operation, at the valve mounting position, the portion of the insertion part on the valve body side of the apex of the locking projection is pinched between the nipping pieces. The first feature is that the locking projection and the holding piece are configured such that the opening resistance of the holding piece by the locking projection is greater when the valve is mounted than when the valve is detached from the socket of the valve.

In addition to the above features, the present invention provides a valve mounting position in which one end of the valve body is engaged with the socket of the socket.
The second feature is that the locking projections are arranged so that the closing operation of the sandwiching piece with respect to the locking projections is terminated halfway.

(2) Operation According to the first feature, when the valve is mounted, the opening resistance of the socket-side clamping piece by the locking projection is set to be large, and the pushing resistance of the valve into the socket suddenly increases and then suddenly increases. Therefore, the operator feels a great degree of moderation and reliably pushes the valve to the proper mounting position. Further, when the valve is detached, the opening resistance of the holding piece by the locking projection is set to be small, so that the operator can easily remove the valve from the socket with a comparatively light pulling force.

Further, in particular, the above-mentioned holding piece is provided separately from the insertion hole and the socket side terminal so that at the valve mounting position, the portion of the insertion portion closer to the valve body than the apex of the locking projection is held between the holding pieces. Therefore, not only the valve body is supported by the socket receiving port and the insertion portion is supported by the socket insertion hole, but also the portion of the insertion portion on the valve body side with respect to the apex of the locking protrusion. Is firmly sandwiched between the sandwiching pieces, so that the valve is firmly supported as a whole. Moreover, since the locking protrusion and the sandwiching piece can be provided independently of the valve side terminal exposed on the side surface of the insertion portion and the socket side terminal exposed on the inner side surface of the insertion hole, the electrical contact portion between these terminals is provided. In this case, it is not necessary to apply a relatively large load that the locking projection receives when passing through the sandwiching piece when the valve is attached or detached.

Further, according to the second feature, at the valve mounting position, the sandwiching piece exerts a closing force to apply a retracting force to the locking projection, so that it cooperates with the socket receiving end that engages with the end of the valve body. Therefore, the mounting posture of the valve can be further stabilized.

(3) Embodiment An embodiment of the present invention will be described below with reference to the drawings.

First, referring to FIG. 1 showing a first embodiment of the present invention, a vehicle stop lamp / taillight bulb / socket assembly 1 comprises a bulb 2 and a socket 3 to which the bulb 2 is mounted.

As shown in FIGS. 1 and 2, the valve 2 includes a valve body 4 in which first and second filaments 6 ₁ and 6 ₂ are enclosed.
And a flat insertion portion 5 protruding from one end surface of the valve body 4. On each of the wide side surfaces of the insertion portion 5, a pair of terminals 7 ₁ , 7 ₁ connected to the filaments 6 ₁ , 6 ₂ are formed.
7 ₂ and 7 ₂ are respectively arranged and at least both terminals
7 ₁ , 7 ₁ ; locking protrusions 8, 8 extending laterally between 7 ₂ and 7 ₂
Are integrally formed.

As shown in FIG. 1A, each locking projection 8 has a front slope a on the tip side of the insertion part 5 and a rear slope b on the base side, and the inclination angle α of the front slope a is It is set to be larger than the inclination angle β of the slope b.

On the other hand, the socket 3 is, as shown in FIGS. 1 and 3,
Receptacle 10 with which one end of valve body 4 can be engaged, and insertion portion 5
And a flat insertion hole 11 into which the A pair of terminals 12 ₁ , 12 ₁ ; 12 ₂ , 12 ₂ are provided on the wide inner surface of the insertion hole 11, and the insertion portion 5 is inserted into the insertion hole 11. At this time, the terminals 7 ₁ , 7 _{1 and} 7 ₂ , 7 ₂ are in contact with each other.

As shown in FIGS. 1 and 1A, the socket 3 has
A pair of elastic sandwiching pieces 13, 13 projecting toward both wide side surfaces of the inserting portion 5 are integrally provided at an intermediate portion between the receiving port 10 and the inserting hole 11 so as to integrally project. These holding pieces 13 and 13 are adapted to be elastically opened and closed by the locking projections 8 and 8 from the front of the mounting position of the bulb 2 to the socket 3 to the mounting position. To make a and b slippery,
The free end is rounded.

Next, the operation of this embodiment will be described.

When mounting the valve 2 in the socket 3, the operator takes a picture of the valve body 4 with his fingertip and pushes the insertion portion 5 into the insertion hole 11 from between the two clamping pieces 13, 13. Then, first, the terminals 7 ₁ and 7 ₂ contact the corresponding terminals 12 ₁ and 12 ₂ , respectively, and then the locking protrusions 8 and 8 2.
Enters between the sandwiching pieces 13 and 13 and pushes open the space between the locking pieces 13 and 13 against their elastic force by the steep slopes a and a at the front part, so that the pushing resistance increases sharply.

When the apexes of the locking projections 8 and 8 pass between the sandwiching pieces 13 and 13, the pushing resistance not only decreases sharply but also the sandwiching pieces 13 and 13
Is pressed against the rear slopes b and b by its own restoring force,
Rather, the locking projections 8, 8 are given a pulling force toward the insertion hole 11 side.
Therefore, the valve 2 is rapidly pushed to the mounting position by receiving a large pushing force of the operator and the pulling force. That is, the pushing stops when the end of the valve body 4 engages with the socket 10 of the socket 3.

As described above, when the valve 2 is mounted in the socket 3, the pushing resistance increases sharply before the mounting position and then sharply decreases, so that the operator can feel a great degree of moderation and secure the valve 2 to the regular mounting position. Will be pushed into.

And, even if the valve 2 reaches the mounting position as described above,
The holding pieces 13 and 13 continue to engage with the lower portions of the rear slopes b and b and do not lose the pulling force with respect to the locking projections 8 and 8;
The mounting posture of the valve 2 can be stably maintained in cooperation with the receiving port 10 that engages with.

Next, when the valve 2 is detached from the socket 3, the operator takes a picture of the valve body 4 with his fingertip and pulls it toward you. Then, this time, the rear slopes b, b of the locking projections 8, 8 push open between the sandwiching pieces 13, 13 against their elastic force, so that pull-out resistance occurs, but the rear slope b is Since the slope is gentler than the slope a, the pullout resistance is relatively small. Therefore, even if the fingertip of the valve body 4 is slippery, it is possible to easily take out the valve 2 from the socket 3 by causing the locking projections 8 and 8 to escape from between the holding pieces 13 and 13 with a comparatively light pulling force. it can.

FIG. 4 shows a second embodiment of the present invention, in which the shape of the engaging portion between the engaging projections 8 and 8 of the insertion portion 5 and the holding pieces 13 and 13 is reversed. is there. That is, each locking projection 8 is given a semicircular cross-sectional shape, while the front end of each holding piece 13 has a front slope a on the side of the receptacle 10 and a rear slope b on the opposite side. A mountain shape is given, and the inclination angle α of the front slope a is set to be larger than the inclination angle β of the rear slope b.

Other configurations are the same as those in the previous embodiment, and in the figure, parts corresponding to those in the previous embodiment are designated by the same reference numerals.

Also in this embodiment, when the valve 2 is attached to the socket 3, after the locking projection 8 pushes open the holding piece 13 from the steep slope a side, a relatively large pushing resistance is generated.
Since it decreases sharply, a great sense of moderation can be given to the operator. Further, when the socket 2 is detached, the locking projection 8 pushes the holding piece 13 from the gentle slope b side, so that even a relatively light pulling force is exerted. The valve 2 can be removed from the socket 3.

C. Effect of the Invention As described above, according to the first feature of the present invention, the socket is provided with the elastic gripping piece projecting toward the side surface of the insertion portion, while the side surface of the insertion portion of the valve is provided. From the front of the mounting position to the mounting position, an engaging projection is provided that engages the clamping piece to open and close it, and when the opening resistance of the clamping projection due to the locking projection separates from the valve socket. Since it is configured to be larger when mounted, the operator has a great sense of moderation when mounting the valve,
This can be securely attached to the socket, and when detached, the valve can be easily removed from the socket with a relatively light pulling force.

Also, in particular, the elastic clamping piece is provided in the socket separately from the insertion hole and the socket side terminal, and at the valve mounting position, the portion of the insertion portion closer to the valve body than the apex of the locking projection is clamped between the clamping pieces. Since the valve body and the insertion part are not only supported by the socket and the insertion hole of the socket, respectively, the valve body side of the insertion part is closer to the valve body than the apex of the locking projection. The portion is firmly sandwiched between the sandwiching pieces, so that the valve is supported as a whole as a whole, and the valve can be held very stably in the socket against vibration and the like. Moreover, since the locking protrusion and the sandwiching piece can be provided independently of the valve side terminal exposed on the side surface of the insertion portion and the socket side terminal exposed on the inner side surface of the insertion hole, the electrical contact portion between these terminals is provided. In this case, it is not necessary to apply a comparatively large load that the locking projection receives when passing through the sandwiching piece due to the attachment / detachment of the valve, and therefore it is effective in preventing early wear or damage of the electrical contact portion. .

Further, according to the second feature, at the valve mounting position where one end of the valve body is engaged with the socket of the socket, the locking projection is provided so as to end the closing operation of the holding piece with respect to the locking projection. Since it is arranged, at the valve mounting position, the sandwiching piece exerts a pulling force on the locking projection to continue pushing the end portion of the valve body to the socket socket, thereby further stabilizing the mounting posture of the valve. It is possible to prevent fluctuation of the illumination direction due to vibration.
