The present invention relates to a car battery plug that is inserted into a cigarette lighter socket of an automobile, and more specifically, to a cigarette lighter socket having a different aperture used in an old car, a Japanese car, and an American car. The present invention relates to a car battery floc with a function of preventing misinsertion as well as obtaining sufficient storage intelligence.

In general, a cigarette lighter socket (hereinafter, simply referred to as a socket) of an automobile has a connection car battery plug for supplying power to an electric device mounted in a vehicle such as a lighting device or a car stereo. Although the charging method of electric sockets is common throughout the world, the socket diameter of old cars is large, whereas the socket diameter of Japanese and American cars is slightly smaller. Thus, by adjusting the amount of protrusion from the plug body outer periphery of the leaf spring contact in accordance with the diameter of the electric socket so that these apertures can correspond to one socket of a vehicle battery plug (hereinafter simply referred to as a plug). The floc which made it possible to obtain maintenance power is proposed by the present applicant (No. 4-17339). That is, as shown in Figs. 8 to 9, the normal plug body 21 to be inserted into the socket 20, and the fixed end is fixed to the inside of the electric plug body 21, the spring end is electric A pair of leaf spring-like contacts 23 protruding from the contact openings 22 cut out on the outer circumference of the plug body 21 to the outer circumference of the plug body 21, and the outer circumferential portion of the fuse holding portion 24 A pair of sliders 25 for protruding adjustment slidingly contacted with the inner surface of the spring ends 23a of the electrical contacts 23 and 23 and integrally connected to the rear ends of the sliders 25. And (b) a flocks made of adjustment knobs 26 protruding protrudingly through the window portion 21a open to the outer periphery of the rear portion of the electric plug body 21.

In addition, reference numeral 27 denotes an external fuse terminal for a cap which protrudes at the tip of the electric plug body 21, 28 denotes an internal fuse terminal, 29 denotes an overcurrent protection fuse, 30 denotes an end of one-stage scale, Numeral 31 denotes an end portion of the two-stage scale, and numeral 32 denotes the amount of protrusion from the outer circumference of the plug body of the contact 23, respectively.

As shown in FIG. 8, for the old parking lot having a large diameter of the socket 20 due to the flocks formed as described above, the electric adjustment knob 26 is slid in a predetermined direction (left direction in the drawing) to form the contact 23. The protrusion amount 32 is increased, and the inner wall surface of the socket 20 and the outer surface of the contact 23 are strongly brought into contact with each other to secure sufficient holding force.

In addition, with respect to the socket 20a having a small diameter in Japanese cars and the like, as shown in FIG. 9, the electric adjustment knob 26 is slid in the reverse direction (the right direction in the drawing) to protrude the contact 23. (32) is made small. However, the above-mentioned flocks correspond to sockets of different sizes with one type, but lack the function of preventing the misinsertion of the flocks. That is, when the contact of the electric plug is set to a large amount of protrusion for a large-sized opening, and the driver or the like is forcibly plugged into a socket of a Japanese car having a small diameter, the curved portion of the contact is deformed. Therefore, if the plug with the deformed contact is plugged into a socket having a large diameter, the contact resistance between the contact and the socket becomes extremely small at this time, so that sufficient holding force cannot be obtained, and the plug may fall out of the socket. there was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and provides a car battery plug having a function of preventing misalignment to prevent contact slippage, while also providing sufficient storage capacity in correspondence to cigarette lighter sockets having different apertures. The purpose.

Summary of the Invention The present invention solves the above problems and achieves the above object, a conventional plug body for plugging into a cigarette lighter socket, a fixed end is fixed inside the electric plug body, and a spring end is cut out on the outer periphery of the electric plug body. A pair of leaf spring-like contacts arranged to protrude from the installed contact openings to the outer periphery of the plug body, a pair of sliders arranged to slide on the outer periphery of the fuse, and to adjust the amount of protrusion of the spring ends of the electrical contacts; Sliding spring plate interposed between the electrical contact and the sliding contact portion of the electric slider, and integrally installed to the outer peripheral portion of the electric slider, and protrudes slidably through the window opening on the outer circumference of the electric plug body In the vehicle battery flocks consisting of adjustment knobs, an electric cone is placed at the distal end of the spring for electric contact. When the amount of contact protruding from the contact opening is increased, when the protrusion protrudes from the contact opening and the plug is inserted into a socket having a small diameter, a stopper is provided which collides with the inlet edge of the socket and prevents the insertion of the electric plug. .

In addition, as described in the second claim, the stopper acting as described above is provided at both edges of the inner side of the electric slider which is in sliding contact with the slider in the vehicle battery flocks.

In addition, as described in the third claim, the stopper acting in the same manner as described above is provided on both side edges of the inner side of the vehicle battery floc which is in contact with the sliding spring plate for the contact tip.

The plug according to the present invention is operated by a stopper placed at the distal end of the sliding spring plate so that the protrusion of the contact is increased at the contact opening of the plug body so as to correspond to a socket having a large diameter by operating the adjusting knob. The stopper of the sliding spring plate also protrudes from the opening for the electrical contact. When the plug in this state is plugged into a large-bore socket, the electric stopper is inserted into the socket without impacting the entrance edge of the socket. On the other hand, when this plug is inserted into a socket having a small diameter, the end face of the electric stopper collides with the inlet edge of the socket, and further insertion is prevented. In this way, if the plug is inserted into a socket having a small diameter while the protrusion amount of the contact is increased, misinsertion is prevented.

When the adjustment knob is operated so that the contact of the plug corresponds to a socket having a small diameter, the amount of protrusion of the contact is reduced, so that the electric stopper does not protrude from the opening for the contact, but is embedded in the inside of the plug body. The 2nd and 3rd Claims are the modification which modified the location which provided the stopper, and the action and effect of the stopper are the same as that mentioned above.

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

In addition, in order to understand easily, the thing corresponding to the conventional example is shown with the same code | symbol.

The gist of the plug 1 of the present invention increases the amount of protrusions 32 from the contact openings 22 of the contacts 2, 3 of the plug 1, thereby increasing the size of the sockets (for example, for parking). When the plug 1 in this state is inserted into a socket having a small diameter (for example, a Japanese car) at a time, it is prevented from being misinserted by the stopper 6 provided on the sliding spring plates 4 and 5. Is in.

The configuration of the plug 1 according to the present invention is described with reference to FIG. 2, which is an ordinary plug body 7 inserted into the cigarette lighter socket 20 of an automobile, and protrudes from the tip of the plug body 7. The terminal 10 is brought into contact with the electrode of the electric socket 20, and the front end thereof is in contact with the rear end of the terminal 10, and the other end thereof is connected to the fuse terminal 13 via the fuse holding part and the terminal part 12. Exposed over-current prevention fuse 29, the connecting member 11 to tighten the contact portion of the terminal 10 and the fuse 29, and the fixed end is fixed to the interior of the electric plug body (7) And a pair of leaf spring-like contacts 2 having the spring ends 2a and 3a projected from the contact openings 22 cut out on the outer circumference of the electric plug body 7 to the outer circumference of the plug body 7; 3) and a protruding tub which is disposed freely on the outer circumferential portion of the electric fuse 29 and is in sliding contact with the inner side of each electrical contact 2,3. A pair of fixed sliders 8, sliding spring plates 4 and 5 interposed between the sliding contacts of the electric contacts 2 and 3 and the electric slider 8, and the outer peripheral part of the electric slider 8 It consists of an adjustment knob 9 which is integrally addressed and slidably protrudes through the window portion 14 (see FIG. 4 (b)) opened on the outer circumference of the electric plug body, and includes an electric sliding spring plate 4, The stopper 6 which bend | folded and installed in the front-end | tip part of 5) upward from the both edges is provided. In addition, a cap 16 covering the electric terminal 10 and the connecting member 11 is fixedly fixed to the distal end portion 15 of the plug body 7 by means of screwing or the like, and the rear end portion of the electric contact 2 is fixed. The ends of the electric cord (not shown) are respectively connected to the cord connection terminal 17 and the electric fuse terminal 13, which are presented in the drawing, and are drawn out to the outside from the rear end opening 7a of the plug body 7.

The stopper 6 provided in the electric sliding spring plates 4 and 5 is demonstrated. As shown in Figs. 3 (a) and (b), in each of the front end portions of the sliding material spring plates 4 and 5, the board member is bent upwardly at a substantially right angle from the plate both sides edges of the front end portion. In addition, as shown in the figure, the upper portion of the electric bending plate member is provided with stoppers 6 and 6 having a shape protruding from the spring plate body in the left direction.

The appearance of the floc 1 provided with the sliding spring plates 4 and 5 and the contacts 2 and 3 provided with such a stopper 6 is shown in FIG. When the electric plug 1 is inserted into the socket 20 having a large diameter such as an old parking lot, the adjustment knob 9 is set to the position L as shown in FIGS. 1 and 4. . Then, the slider 8 which becomes the sliding material inside the flop main body 7 is slid to the front end side (left direction in FIG. 1), and the sliding spring plate (by the projection part 8a of the slider 8) 4, 5 and the spring ends 2, a, 3a of the contacts 2, 3 are pushed up in the outer circumferential direction of the plug body 7. Therefore, the contacts 2 and 3 protrude from the contact openings 22 of the plug body 7, the protruding amount 32 becomes large, and the stopper of the tip end of the spring plates 4 and 5 for electric contact. (6) The upper end portion projects from the electrical opening portion 22. In this state, when the plug 1 is directly inserted into the socket 20 having a large diameter of the vehicle, the upper end side of the electric stopper 6 is inserted without any lower contact without touching the inlet edge of the socket 20.

However, if the plug 1 is inserted into the socket 20a having a small diameter as it is, the protrusions 32 of the contacts 2 and 3 of the plug 1 shown in FIG. As shown in the figure, the distance from the center axis of the plug 1 of the front end 6a of the tip side of the electric stopper 6 protruding from the contact opening 22 is greater than the radial dimension of the inner wall branches of the socket 20a. Therefore, the tip 6a of the exhibition stopper 6 collides with the inlet edge 20b. In this way, misinsertion of the aforementioned flocks 1 is prevented. In addition, as shown in FIG. 2, the adjustment knob 9 is set to the S position so as to correspond to the socket having a small aperture, and the slider 8 is retracted to the rear end side of the plug body 7 so that the contacts 2, 3 In the case where the protrusion amount 32 of the ()) is made small, the stopper 6, which has been delivered together with the sliding spring plates 4 and 5, is also embedded in the plug body 7, so that no obstacle is caused.

As mentioned above, although the floc 1 which concerns on this invention was formed, it is not limited to the said embodiment, The shape of the electric stopper 6 can be changed suitably.

As another example, a stopper may be provided on the contacts 2 and 3. For example, as shown in FIG. 6, the inner part 2c which integrally protrudes from one spring end is provided with respect to the above-mentioned contacts 2 and 3 so that it may directly contact an electric slider 8, and the inner part 2c The contact 2b provided with the stoppers 6b and 6b which were erected upward from both side edges of the side). As illustrated, the electric stopper 6a is thin and long in the lateral direction, and is suitable for receiving the force in the lateral direction. In this case, the sliding spring plates 4 and 5 shown in Figs. 1 to 2 are not required because the electric inner portion 2c slides. The action and effect of the stopper 6b of this contact 2b are the same as described above. In addition, as shown in FIG. 7, the contact 2d in which the stopper 6c is provided inside the front-end | tip part of the contacts 2 and 3 may be used. Therefore, even when a sliding spring plate of the form without the stopper 6 of the springs 4 and 5 for electric sliding is used, the tip of the stopper 6c of the electrical contact 2d has a small diameter. The collision with the inlet edge portion 20b is prevented from being deformed. Actions and effects on the stopper 6c of the electrical contact 2d are also the same as described above, and description thereof is omitted.

As described above, the automotive battery floc according to the present invention has a large amount of protrusion of the electrical contact at the tip of the sliding spring plate interposed between the slider and the inner shaft of the contact protruding from the contact mechanism of the plug body. Since a stopper is installed to protrude from the opening for electrical contact and hits the inlet edge of the socket having a small diameter, and prevents the insertion of the plug. Therefore, the plug is prevented from being misinserted and the contact is not misaligned. To improve.

According to the second claim, the stopper is provided on the contact, and the sliding spring plate also serves as a double blade, which achieves the same effect as described above and reduces the number of parts.

As in the third claim, even if a stopper is provided on the inner side of the contact tip side, the same effect as in the first claim can be obtained.
