Heretofore, it has been difficult for a plug connected (connected) to an outlet to be pulled out from the outlet without pulling the plug considerably strongly. Also, when pulling out the plug inserted into the extension outlet, both the outlet and the plug had to be strongly pulled together. [0003] Conventionally, a large force is required for pulling out in this manner, and there is a risk that the connection between the plug and the cord may be damaged. Therefore, the present invention solves such a conventional problem, and provides a plug which is normally securely connected to an outlet and can be easily pulled out with a small force when it is desired to separate the plug. The purpose is to: SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a body and a pair of plug terminals having a base end buried in the body and protruding from a front surface of the body. A reciprocating member with a rod disposed between the terminals and capable of protruding and retracting from the front surface of the body, and retracting the reciprocating member into the body to resiliently move the rod into a retracted state. A biasing resilient member, and a pair of swing operation levers pivotally attached to the body so as to freely expand and contract on both sides of the body. provided interlocking coupling mechanism for interlocking the projecting operation of the reciprocating member, further, it provided a pivot shaft and the engaging pin portion to the pivoted lever and the arm of the engaging pin portion and the pivot shaft Rather than the length of the arm between the pivot shaft and the operating portion of the swing operation lever. Increase set, double force structure by the lever and Then co
The reciprocating member has a rectangular portion having a horizontally long hole on the base end side.
And the rod is continuously provided from the rectangular portion,
The rocking operation lever is located at both ends of the center of the body.
Pivotally mounted on the pivot shaft and reciprocating the engagement pin portion
The engaging pin portion is engaged with the oblong hole on the base end side of the member.
And the above-mentioned interlocking connection mechanism is constituted by the oblong hole.
is there. The present invention will be described in detail with reference to the drawings showing the following embodiments. FIGS. 1 and 2 show an embodiment of a plug according to the present invention. The plug 1 comprises a plastic body 2 and a pair of plug-side terminals 3 projecting from a front surface 2a of the body 2. , 3 are provided. The body 2 comprises an upper lid 5 and a body main body 6, both of which are connected by screws. Also,
A pair of swing operation levers 4 and 4 protrude from both sides of the rear side edges 2 b and 2 b of the body 2. More specifically, as shown in FIG. 3, the body main body 6 is provided with a pair of concave grooves 13 on the front surface 6a. Further, a pair of elongated grooved holding portions 9, 9 are provided from the front surface 6a side to the center. In addition, the elongated groove communicates with the concave groove portion 13, and the base ends of the pair of plug terminals 3 are buried. A reciprocating member 8 is attached to the upper portions of the holding portions 9 and 9. The reciprocating member 8 has a rectangular portion having a horizontally long hole 10 on the base end side, and a rod 7 is continuously provided on the lower surface side of the rectangular portion, and is disposed between the holding portions 9, 9. I have. That is, the rod 7 of the reciprocating member 8
Is provided so as to protrude and retreat from the front surface 2 a of the body 2 and slide between the terminals 3. On the rear surface 6b side of the body main body 6,
A pair of grooves 14 is provided, and a plug 21 for an electric appliance or the like is provided.
(See FIG. 5) can be inserted in the direction of arrow A. Further, a resilient member 12 such as a coil spring is fitted on the rod 7. The spring member 12 pulls the reciprocating member 8 back into the body 2 and urges the rod 7 to the retracted state. Next, a pair of swing operation levers 4 and 4 are pivotally attached to the body 2 so as to freely expand and contract on both sides of the body 2. That is, the levers 4 and 4 are in the expanded state when the resilient member 12 is in the free state (as shown in FIG. 3). More specifically, the swing operation lever 4
Has a pivot shaft 16 at the right end of the front edge of the back surface, and an engaging pin portion 15 that engages with the elongated hole 10 of the reciprocating member 8 at the left end. The pair of swing operation levers 4, 4
Are inserted into the short cylindrical portions 17 and 17 provided at both ends of the center of the body main body 6 so that the pivot shafts 16 and 16 are pivotally attached thereto, and the engaging pin portions 15 and 15 are inserted into the oblong holes 10. Is engaged. As described above, the engagement pin portions 15, 15 and the oblong hole 10 and the like are interlocked with the operation of the swing operation levers 4, 4 in the expanding and contracting width directions.
An interlocking connection mechanism G for interlocking the reciprocating and projecting operations of the reciprocating member 8 is configured. FIG. 4 is an operation diagram showing the interlocking connection mechanism G. When the action portion F of the swing operation lever 4 is pressed in the direction of the arrow M, the lever 4 swings in the direction of the arrow J as indicated by a virtual line. As the engagement pin portion 15 swings due to the swing, the reciprocating member 8 engaged with the pin portion 15 slides in the direction of arrow K as indicated by a virtual line. That is, in the interlocking connection mechanism G, the force applied (by the finger) in the direction of the arrow M is converted into an arc movement of the lever 4 in the direction of the arrow J. This mechanism is converted into a linear motion in the direction of arrow K. [0016] Moreover, the arm length L 0 of the pivot shaft 16 and the engaging pin portion 15, and the arm length L 1 between the working portion F of the pivot shaft 16 and the rocking lever 4 It has a leverage boost structure. That is, the arm length L 1 between the working portion F of the pivot shaft 16 and the rocking lever 4 is set larger than the length L 0 of the arm with the pivot shaft 16 and the engaging pin portion 15 Thus, even if the lever 4 is pressed with a small force, the reciprocating member 8 can be slid with a large pressing force. The action portion F indicates a portion where a human finger contacts the operation lever 4. Next, a method of extracting the plug 1 from the outlet C will be described. First, as shown in FIGS. 5 and 6,
When a force is applied to the pair of swing operation levers 4 and 4 of the plug 1 inserted into the outlet C with one finger in the directions indicated by arrows M and M, the width of the operation levers 4 and 4 is reduced. The reciprocating member 8 slides in the direction of the arrow K by the interlocking connection mechanism G described above along with the swing in the direction of the arrow J. Accordingly, the rod 7 is connected to the body 6
, The tip 7a of the rod 7 strongly presses the surface of the outlet C, and the plug 1 is pushed out in the direction of arrow E. Thus, the plug 1 can be easily pulled out from the outlet C. After the plug 1 is pulled out from the outlet C, the resilient member 12 in the contracted state attempts to return to the free state, and the rod 7 projecting from the front surface 2a is moved to the body 2 to return to the free state.
The rod 7 is elastically urged in a direction of being pulled back into the inside of the rod to bring the rod 7 into a retracted state. With this operation, the pair of swing operation levers 4 and 4 shifts to the expanded state, and returns to the state shown in FIG. The present invention can be freely modified in design other than the above-described embodiment. For example, as shown in FIG. 3, without providing the concave grooves 14, 14 and the plug insertion receiving portions 23, 23 on the rear surface 6b side of the body main body 6, the electric appliance or the like is provided at the base end of the plug terminal 3. It is also preferable to directly connect the conductor of the cord projecting from the rear surface, and to project the cord from the rear surface 6b. The present invention has remarkable effects as described below. [0022] According to the first aspect, the swing operation levers 4, 4 are easily pressed in the width reducing direction {the directions approaching each other}. ,
The plug 1 firmly connected to the outlet C can be pulled out from the outlet C with a small force, which is convenient. Further, since the plug 1 can be pulled out from the outlet C while keeping the horizontal stationary state, there is no danger of damaging the connection between the plug 1 and the cord. That is, the operation of clamping the pair of swing operation levers 4 and 4 with the fingers of the hand in the approaching direction and the operation of pulling out the plug 1 are very natural movements. , 3 can be smoothly pulled out of the outlet C (without twisting or falling over the outlet C). In addition, it is easy to apply finger pressures M, M (see FIG. 5). It is possible to obtain a large protruding force of the rod 7 (ie, a pulling force of the plug 1 from the outlet C) by a small pressing force, so that the plug 1 can be more easily pressed with a small force. It can be pulled out from outlet C.
