Abstract
The utility model relates to the technical field of a plug, in particular to an inner frame of the plug; the inner frame of the plug comprises a cylindrical contact pin and a colloid; the colloid comprises an external colloid and a filling colloid which are formed into one body by injection; the external colloid and the filling colloid are closely combined together by injecting formation; the inner part of the contact pin is a hollow structure; the consumptive material of the contact pin with the hollow structure is few, the weight is light, and the cost is low, and the contact pin can be processed by utilizing punching and stretching; the traditional process that the contact pin is manufactured by processing solid bar material by lathe turning is changed into a new process that the contact pin is processed by punching, the processing is convenient, thus improving the production efficiency and reducing production cost; the filling colloid is filled in the hollow structure at inner part of the contact pin and strengthens the rigidity, strength and torque moment of the contact pin, thus leading the inner frame of the plug formed by the contact pin with hollow structure to pass through product security certification and achieving same performance and function of the inner frame of the plug which is manufactured by traditional contact pin.
Description
Technical field:
The utility model relates to the plug technical field, particularly a kind of plug internal frame.
Background technology:
Plug was widely used in being connected of electrical equipment and power supply, and along with the development of electrical apparatus industry, people are also more and more higher to the requirement of plug.Existing plug internal frame includes cylinder type contact pin and colloid, colloid and contact pin injection mo(u)lding are closely linked and form the plug internal frame, but original traditional contact pin is a solid construction, and consumptive material is many, Heavy Weight, the contact pin traditional processing technology uses lathe turning processing, processing is inconvenient, and production efficiency is low, causes the cost height, in today that the plug demand increases day by day, the serious waste resource.
The utility model content:
The purpose of this utility model is that to provide a kind of contact pin at the deficiencies in the prior art be the few plug internal frame of hollow-core construction, consumptive material.
For achieving the above object, the utility model adopts following technical scheme:
A kind of plug internal frame, it includes cylinder type contact pin and colloid, described colloid includes outside colloid and the filling colloid that injection mo(u)lding is integral, outside colloid and contact pin injection mo(u)lding are closely linked, contact pin inside is hollow-core construction, the outer surface of contact pin offers the hole that communicates with hollow-core construction, fills colloid and is filled in the hollow-core construction of contact pin inside, fills colloid and links into an integrated entity by hole and outside colloid.
The top of described contact pin is provided with opening horn mouth up.
The outer surface of described contact pin is circumferentially with groove, and the groove of outside colloid and contact pin is closely linked.
Described hole is positioned on the groove.
The utility model beneficial effect is: the utility model includes cylinder type contact pin and colloid, described colloid includes outside colloid and the filling colloid that injection mo(u)lding is integral, outside colloid and contact pin injection mo(u)lding are closely linked, contact pin inside is hollow-core construction, the contact pin consumptive material of hollow-core construction is few, in light weight, cost is low, economize on resources, can utilize punching stretch forming processing, this contact pin will use the traditional handicraft of lathe turning processing solid bar originally, change into the new technology of using punch press processing, easy to process, improved production efficiency, reduce production costs, filling colloid is filled in the hollow-core construction of contact pin inside, fill colloid and strengthened the rigidity of contact pin, intensity and moment of torsion, the formed plug internal frame of contact pin with hollow-core construction can be authenticated by product safety, reach and same performance and the function of plug internal frame of using traditional contact pin to produce; In addition, the outer surface of contact pin offers the hole that communicates with hollow-core construction, filling colloid is filled in the hollow-core construction of contact pin inside, filling colloid links into an integrated entity by hole and outside colloid, can conveniently carry out injection moulding to the hollow-core construction of contact pin by the hole fills, make fill colloid and colloid can integrated injection molding, thereby contact pin firmly is fastened on the colloid, contact pin is not easy to become flexible or come off.
Description of drawings:
Fig. 1 is a partial sectional view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the structural representation of the utility model contact pin;
Fig. 4 is the cutaway view of the utility model contact pin.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see Fig. 1～4, a kind of plug internal frame, it includes cylinder type contact pin 1 and colloid 2, described colloid 2 includes outside colloid 21 and the filling colloid 22 that injection mo(u)lding is integral, outside colloid 21 is closely linked with contact pin 1 injection mo(u)lding, contact pin 1 inside is hollow-core construction 11, contact pin 1 consumptive material of hollow-core construction 11 is few, in light weight, cost is low, can utilize punching stretch forming processing, this contact pin 1 will use the traditional handicraft of lathe turning processing solid bar originally, change into the new technology of using punch press processing, easy to process, improved production efficiency, reduce production costs, and horn mouth 12 can conveniently insert lead in contact pin 1 body.
The outer surface of contact pin 1 offers the hole 13 that communicates with hollow-core construction 11, the both sides of contact pin 1 are run through in hole 13, filling colloid 22 is filled in the hollow-core construction 11 of contact pin 1 inside, filling colloid 22 links into an integrated entity by hole 13 and outside colloid 21, can conveniently carry out injection moulding to the hollow-core construction 11 of contact pin 1 by hole 13 fills, make fill colloid 22 and outside colloid 21 can integrated injection molding, thereby contact pin 1 firmly is fastened on the colloid 2, contact pin 1 is not easy loosening or comes off.Fill colloid 22 and strengthened rigidity, intensity and the moment of torsion of contact pin 1, the contact pin 1 with hollow-core construction 11 can be authenticated by product safety, reach and same performance and the function of plug internal frame of using traditional contact pin 1 to be produced.
The outer surface of contact pin 1 is circumferentially with groove 14, hole 13 is positioned on the groove 14, outside colloid 21 is closely linked with the groove 14 of contact pin 1, groove 14 has increased outside colloid 21 after the injection mo(u)lding and adhesion between the contact pin 1, when preventing that contact pin 1 is subjected to axial impact, contact pin 1 breaks away from outside colloid 21.During injection mo(u)lding, the hollow-core construction 11 that colloid 2 entered and filled contact pin 1 by hole 13 forms and fill colloid 22, and the colloid 2 in contact pin 1 outside forms outside colloid 21, simultaneously outside colloid 21 is linked together with filling colloid 22, to increase the bond strength of contact pin 1 and colloid 2.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
