Abstract

The utility model discloses a three-pin plug which comprises copper pins, power supply wires and a plastic housing. The number of the copper pins is three. The number of the power supply wires is three. The three power supply wires and the three copper pins are respectively connected in the plastic housing. The three copper pins are fixed on one end of the inner part of the plastic housing and are connected with the three power supply wires in one-to-one correspondence through copper sheets. The leading-out directions of the copper sheets are perpendicular to the length directions of the copper pins. The side surface of the plastic housing is an inwards-concave arc surface. The three-pin plug has the advantages that the structure and the machining manner of the copper pins is changed, so that the rejection rate of the copper pins is lowered, the thickness of the plastic housing is reduced, many unnecessary parts are got rid of, and the application amount of plastic is reduced; the size of the plastic housing is reduced, molds with more mold cavities can be used for production under the same equipment condition, and the production efficiency is increased; in addition, the appearance of the plug is beneficial for grasping.

Description

The junction of the rear end face of described plastic shell and two sides is equipped with the arc transition one of indent.

The rear end face of described plastic shell and the junction of end face are provided with the arc transition two of indent.

The junction of the front end face of described plastic shell and two sides is equipped with chamfering.

The middle part of described copper PIN pin is connected with support, and three described copper PIN pins are connected on same support, and described support is positioned at plastic shell.

(3) beneficial effect

Technique scheme tool has the following advantages: by the mode of copper sheet is set between copper PIN pin and power line, replaced the connected mode of original copper PIN pin and power line riveted joint, shortened the length of copper PIN pin, reduced the thickness of plastic shell; End face, bottom and the side of plastic shell is equipped with the arc structure of indent, removed a lot of unnecessary parts, reduced the use amount of plastic cement, reduced the volume of plug entirety; Under identical appointed condition, can use the more mould of multimode cave number to produce, improve production efficiency; The arc structure of plastic shell bottom and side contributes to grasp, and extracting with update of plug is convenient.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

For ease of describing, plastic shell 2 described in the utility model is defined as follows:

Bottom surface: the face being connected with copper PIN pin 1;

End face: the face relative with bottom surface;

Rear end face: the face at power line 3 exit places;

Front end face: the face relative with rear end face;

Side: remaining two faces in six faces of plastic shell 2.

Fig. 1-3rd, the three overall structure views of inserting plugs described in the present embodiment, three copper PIN pins 1 are parallel to each other and are vertically fixed on the bottom surface of plastic shell 2, and copper PIN pin 1 partial fixing is in plastic shell 2, and another part is positioned at outside plastic shell 2; The rear end face of plastic shell 2 is provided with power line 3 outlets, and power line 3 is drawn from outlet after being connected with copper PIN pin 1.Two sides of plastic shell 2 are interior concaved circular cambered surface 5, between the front end face of plastic shell 2 and end face, be provided with the arc transition 26 of an indent, the junction of the rear end face of plastic shell 2 and two sides is equipped with the arc transition 1 of indent, and the junction of the front end face of plastic shell 2 and two sides is equipped with chamfering; The arranging to facilitate of interior concaved circular cambered surface 5 in use grasps plug, can easily plug be inserted or extract socket; In not affecting internal structure, reduce the volume of plastic shell 2, to reduce the use amount of PVC plastic cement as far as possible.

Fig. 4-6th, the structural representation of copper PIN pin 1, support 7 and copper sheet 8 supports 7 described in the present embodiment.Three copper PIN pins 1 are realized location mutually by same support 7, and this support 7 is also fixed in plastic shell 2; One end that three copper PIN pins 1 are positioned at plastic shell 2 is connected with three power lines 3 by copper sheet 8 respectively, and three power lines 3 are formed a branch of rear end face from plastic shell 2 and drawn.In prior art, copper PIN pin 1 by riveting, is realized itself and being connected of power line by the mode of riveted joint mouthful is set at copper PIN pin 1 afterbody with power line, and riveted joint mouthful need to take certain space, and this has just caused plastic shell 2 meetings thicker; And described in the embodiment of the present application copper sheet 8 draw direction perpendicular to copper PIN pin 1 length direction, take up room less, and copper sheet 8 is thinner, therefore can effectively reduce the thickness of plastic shell 2 entirety, reduce the consumption of PVC plastic cement.

Through evidence, the about 22.5g/ part of PVC plastic cement consumption of plug after improving, compared with original 42.5g/ part, has saved 47% PVC plastic cement consumption, and what be conducive to that company promotes PVC material subdues, abrogates plan, realizes the object of protection of the environment.

225233 calculating of average annual output by this plug in 2012, the plug after improvement can be saved PVC sizing material 4504kg every year, approximately saves 5810 dollars/year of costs.

Plug after improvement, due to small volume, under identical appointed condition, can use 6 cave moulds to replace 4 original cave moulds, and a day production capacity can reach 4800/10 hours, and production capacity can promote 50%.

As can be seen from the above embodiments, the utility model, by the riveted between existing copper PIN pin 1 and power line 3 is connected to the mode connecting by copper sheet 8 that changes into, has reduced the volume of plug inner member greatly; Pass through the mode of the contour structures that changes plastic shell 2 simultaneously, further reduced the volume of plastic shell 2, reduced the use amount of PVC plastic cement; Plastic shell 2 small volumes, in identical device situation, can select die cavity number to produce with many moulds, have effectively improved the production efficiency of plug; The arc transition 1 of the interior concaved circular cambered surface 5 of plastic shell 2 both sides and the indent of bottom also makes the grasping of plug convenient, can not skid easily.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection range of the present utility model.
