The purpose of this utility model provides a kind of unit combination socket that structurally is different from the traditional form plate connector fully.The plate connector of this structure can go out the porous socket of arrangement of various criterion socket aperture and different socket aperture quantity according to different demand utilization socket unit combination in any.And only use two pairs of moulds, and saved production cost, in addition, each different units of this unit combination socket itself is again an independent used jack conversion and an extension socket that practicality is very strong.

Particular content of the present utility model is that each standard socket hole is made in each independently on the socket unit.The unit combination socket mainly is by socket unit, and pedestal and metal are strengthened snap ring and formed.The two ends of unit are respectively attachment plug and gang socket, and respectively there is an annular groove both sides of unit, and the unit that each is identical or different is connected with each other by attachment plug and socket, is plugged on the base unit that has power line again.Put then and strengthen the snap ring reinforcing, just form a complete unit combination socket.Single-phase three-terminal polarized plus plug of GB and socket are all made in the attachment plug of each separate unit both sides of plate connector and gang socket, and therefore, each unit is again an independent used socket aperture conversion and extension socket.This unit combination socket has very flexibility and versatility.

In order to overcome the weakness that the conventional socket body is frangible and socket is easily loose, manufacturing socket unit and base unit is that the direct injection moulding of the copper sheet that connects is formed socket in soft insulating grade polyvinyl chloride, utilize the elasticity of polyvinyl chloride to strengthen the plug elasticity of socket aperture, this structure patent applied for, the patent No.: ZL93226073X.Below in conjunction with accompanying drawing in detail an embodiment is described in detail:

Fig. 1 be each socket unit the contour structures schematic diagram wherein [a] be the assembled unit of single-phase two pole sockets of GB and Europe VDE standard jacks

[b] is the single-phase three pole socket unit of GB

[c] is the single-phase three pole socket unit of U.S. UL standard and Canadian CSA standard

[d] is the single-phase three pole socket unit of Britain's BS standard

[x] is power switch unit

[y] is 250V voltmeter unit Fig. 2-the 1st, and the inside copper sheet arrangement schematic diagram 2-2 of [b] is that external structure and the function diagram 3 of Fig. 1 [b] are that base unit structural representation Fig. 4 is that reinforcement snap ring schematic diagram Fig. 5 is each unit combination schematic diagram among Fig. 1

Each socket unit [a] .[b among Fig. 1] .[c] .[d] .[x] .[y]. overall dimension in full accord, different is the work socket hole type of each upper surface, unit.Fig. 2 is the internal structure external structure signal of [b] unit, is used for representing the internal structure external structure of each unit.Wherein Fig. 2-1 [1] is the inner copper sheet of cell operation socket aperture among Fig. 2-2, [2] be the attachment plug and the gang socket copper sheet of unit, when manufacturing, after earlier work socket copper sheet [1] and attachment plug socket copper sheet [2] homopolarity being interconnected, embed the inserts frame and put into mold cavity, at one end expose attachment plug copper sheet [2] as attachment plug, once be injection molded into unit socket body [3] among Fig. 2-2 with soft exhausted green grade PVC.Other unit is in full accord with the manufacture method of [b] unit, and different is that inner copper sheet is arranged.Because the overall dimensions unanimity of each unit, only need be with the type cavity mould of a unit when producing, when opening molding jig, one side of cell operation face [4] in the die cavity is made interchangeable movable inserts frame, only need to change different jack inlay framves and just can be made into the socket unit ([4 '] are illustrated in the various socket apertures on the working face [4]) of various jacks [4 '], and must not open one pair of mould for each unit.
