DETAILED DESCRIPTION OF THE INVENTION

Depicted inFIGS.1-5is a rotatable puller for a female plug. The rotatable puller1comprises the puller body11and the first rotary connection part12and second rotary connection part13configured on the upper end and lower end of the handle body. When the rotatable puller1is applied in a female plug3, the first rotary connection part12is mounted on the upper end of the female plug3in a rotary manner, the second rotary connection part13is mounted on the lower end of the female plug3in a rotary manner, so that the handle body is assembled with the female plug3, and is capable of rotation in relation to the female plug3. The front end of the female plug3is configured with several slots31, several first terminals are configured inside the slots31for electrical conduction. The first terminals are electrically connected to the first wires32connected with the female plug3.

Referring toFIG.5, the appearance of the female plug3looks like a male plug.

Below are descriptions of the assembly structure of the first rotary connection part12and the female plug3:

The upper end of the female plug3is configured with a connecting column4. The upper end of the connecting column4is formed with a flange41protruding outward. The first rotary connection part12is configured with a first hole121. The size of the first hole121is larger than the diameter of the connecting column4. The size of the first hole121is smaller than the diameter of the flange41. Thus, the first rotary connection part12is fitted on the connecting column4through the first hole121, and is limited on the connecting column4through the blocking of the flange41. Meanwhile, the first rotary connection part12is capable of rotation in relation to the connecting column4. During assembly, the first rotary connection part12is sleeved onto the flange41through the first hole121from top to bottom, and the wall of the first hole121is squeezed to slightly deform the hole. Thus, the first rotary connection part12goes across the flange41and is fitted on the connecting column4. By now, the assembly is completed.

In order to improve the efficiency of assembly, the following designed is provided: the periphery of the upper end of the flange41is configured with a conical surface412for the first hole121of the first rotary connection part12to go through. When the first rotary connection part12is sleeved onto the flange41from top to bottom through the first hole121, the wall of the first hole121can move along the conical surface412, so that the first rotary connection part12can quickly go across the flange41and be sleeved on the connecting column4. The assembly is more convenient and efficient.

In order to limit the rotation angle when the rotatable puller1rotates on the female plug3, the following design is provided: the periphery of the connecting column4is formed with a stopping bump42that protrudes outward. The wall of the first hole121is integrally formed with a limiting protrusion122. When the rotatable puller1rotates around the female plug3till the limiting protrusion122touches the stopping bump42, the rotatable puller1cannot rotate further in the same direction. In this way, the rotation angle is limited.

There are two stopping bumps42, respectively configured on the left and right sides of the connecting column4, and located on the same line. There are two limiting protrusions122, respectively configured on the front end and rear end of the wall of the first hole121, and located on the same line, and in the same direction as the length of the first rotary connection part12. When puller body11of the rotatable puller1is rotated to the lateral side of the female plug3, the limiting protrusion122is blocked by the stopping bump42, to avoid excessive rotation of the rotatable puller1and make sure that the puller body11is rotated precisely to the lateral side of the female plug3.

In order for the limiting protrusion122to go across the flange41more easily, the flange41is configured with a notch411for the limiting protrusion122to go through. Thus, during assembly of the first rotary connection part12and the female plug3, it is more efficient.

The second rotary connection part13is configured with a second hole131, and is sleeved outside the SR head5on the lower end of the female plug3through the second hole131, capable of rotation in relation to the female plug3. During production of the rotatable puller of the invention, it is made together with the plastic part of the female plug3. In other words, the second rotary connection part13and the plastic part of the female plug3are produced together by forming in the same mould, so that the second rotary connection part13can be sleeved outside the SR head5on the lower end of the female plug3through the second hole131. Of course, the following means of assembly is also possible: after sufficient length of the first wire32is prepared for the female plug3, cut the first wire32, and the second rotary connection part13is sleeved in through the second hole13from the position of cutting, and fitted outside the SR head5on the lower end of the female plug3. Finally, the first rotary connection part12is mounted on the connecting column4.

In order to enhance the comfort of the fingers touching the puller body11, the following design is provided: the inner side of the puller body11is formed with a plurality of curved convex parts111and a plurality of curved grooves112between the curved convex parts111to mesh with the fingers. When the user grips the puller body11by hand and the fingers touch the curved grooves112, the user will feel more comfortable. Also, it provides an anti-skidding effect and makes it easier to apply a force to pull out the female plug3. The operation is more convenient.

The first rotary connection part12and second rotary connection part13are both in the shape of a plate, and integrally formed on the same side of the upper end and lower end of the puller body11, forming the shape of a half square frame.

The rotatable puller1is made of soft or hard plastics and integrally produced by plastic forming. During production, manufacturers can choose soft plastics or hard plastics according to practical conditions. If it is integrally formed by hard plastics, the performance will be better and operation easier.

Inside the female plug3, an LED light6is provided. And the female plug3is configured with a light guiding part7corresponding to the LED light6. Thus, when the female plug3is connected to electricity, the LED light6will emit light, and the light will be exposed through the light guiding part7, indicating power-on. The usage is more convenient.

In summary, the rotatable puller1of the invention is mounted on the female plug3in a rotary manner. To pull out the female plug3, turn the puller body11to the rear end of the female plug3. Then, the user can grip the puller body11and apply a force to pull the rotatable puller outward to pull out the female plug3. The invention makes it easy to apply a pulling force, and the operation to pull out the female plug3is simple and easy. When the rotatable puller1is not to be used, the puller body11can be turned to the lateral side of the female plug3, so as to reduce the thickness of the female plug3due to the protrusion of the puller body11on the rear side. And the female plug3can be used normally.

Referring toFIG.6, when the rotatable puller1of the invention is applied in combination with a male plug2, the first rotary connection part2is mounted on the upper end of the male plug2in a rotary manner, the second rotary connection part13is mounted on the lower end of the male plug2in a rotary manner, so that the handle body is assembled with the male plug2, and is capable of rotation in relation to the male plug2. The front end of the male plug2is configured with several conductive inserting plates21. The conductive inserting plates21is electrically connected to the second wire22connected with the male plug2. The structure in the assembly between the present invention and the male plug2is similar to the assembly between the present invention and the female plug3, with the same technical effect, and is therefore not repeated herein.

The rotatable puller1of the present invention is mounted on the male plug2in a rotary manner. To pull out the male plug2, turn the puller body11to the rear side of the male plug2. Then the user can grip the puller body11, and apply a force to pull the rotatable puller outward to pull out the male plug2. When the rotatable puller1is not to be used, the puller body11can be turned to the lateral side of the male plug2, so as to reduce the thickness of the male plug2due to the protrusion of the puller body11on the rear end. Thus, the male plug2can be used normally.
