Description

Electric connector

Technical field

This creation is relevant with electric connector, particularly a kind of electric connector with double-layer staggered arrangement terminal.

Background technology

Consult shown in Figure 1, because the progress of science and technology, the capacity of Data Holding Equipment is also increasing, in order to make the transmission equipment bigger data transfer throughput of loading, electric connector must increase the number of terminal, as USB 3.0 electric connectors, is outside the first terminal group 10 that is compatible to USB1.0/2.0, one group of second terminal group 20 of extra increase is to increase data transfer throughput.The first terminal group 10 and second terminal group 20 need be staggered, and each butt all must isolate mutually, to keep mutual insulating each other.

In order in small space, to fix the staggered the first terminal group 10 and second terminal group 20, normally respectively the first terminal group 10 and second terminal group 20 are embedded in respectively after the first terminal seat 30, second terminal base 40 of insulation, see through positioning seat 50 in conjunction with the first terminal seat 30, second terminal base 40, reach that the first terminal group 10 and second terminal group 20 are staggered and the purpose of mutual insulating.At last, aforesaid assembly and is finished the electric connector that meets the USB3.0 agreement in being incorporated into a shield shell 60.

Though electric connector shown in Figure 1 is arranged terminal in little space effectively and is isolated, but this kind structure manufacture process is complicated, inserting so many assembly in narrow space all has suitable degree of difficulty on making and assembling, so the processing cost of kind structure is all very high.

Summary of the invention

In view of this, this creation proposes a kind of electric connector, comprises a plurality of the first terminals, a plurality of second terminal, a terminal base and an embedded block.Respectively this first terminal comprises one first contact jaw and one first welding ends respectively.Respectively this first terminal is embedded in this terminal base abreast, and those first contact jaws and those first welding endss expose this terminal base.Respectively this second terminal comprises one second contact jaw and one second welding ends respectively.Embedded block forms on this terminal base, and respectively this second terminal is embedded between this embedded block and this terminal base abreast, make respectively this second contact jaw and respectively this second welding ends expose to outside this embedded block.

The electric connector of this creation is used the injection molding technology that coats, terminal base and embedded block just are coated and fixed on those terminals wherein when being shaped, do not need artificial assembling, and those first welding endss and those second welding endss are not contacted with each other, reach the good insulation effect.

Embodiment

Fig. 2-the 5th, this creation electric connector that embodiment discloses, wherein Fig. 2 is this creation terminal base 300 and the first terminal 100 schematic diagrames, Fig. 3 creates the schematic diagram that second terminal 200 is assembled in terminal base 300 for this, and Fig. 4 is this creation embedded block 400 dress schematic diagrames, and Fig. 5 is this creation schematic diagram.

Shown in Fig. 2-5, the electric connector of this creation embodiment comprises a plurality of the first terminals 100, a plurality of second terminal 200, a terminal base 300 and an embedded block 400.

As shown in Figure 2, each the first terminal 100 is conductive metal sheets of strip, and each the first terminal 100 more comprises one first contact jaw 110 and one first welding ends 120; Wherein first contact jaw 110 inserts connector terminals in order to contact, and first welding ends 120 is in order to be welded in the machine plate.

As shown in Figure 2, terminal base 300 is platform-like plastics pedestals, can see through plastics injection molding made.Aforesaid the first terminal 100 is embedded in the terminal base 300 abreast, and wherein the stage casing part of the first terminal 100 is to be coated in the terminal base 300, first contact jaw 110 and first welding ends, 120 bared end stromas 300.110 of first contact jaws need the local surface that exposes to terminal base 300, insert connector terminals with contact; And behind first welding ends, the 120 bared end stromas 300, further stretch out, in order to the operation that is welded in the machine plate (consulting Fig. 2).

Consult shown in Figure 3ly, each second terminal 200 is made with the sheet metal drawing, and when stamping press was finished, each second terminal 200 still was connected in a housing 201, made each second terminal 200 to be moved together with housing 201.Second terminal 200 that links to each other in housing 201, can be positioned over jointly on the terminal base 300, terminal base 300 is provided with a plurality of location notch 310, the second contact jaws 210 and inserts 310 location in the location notch, makes each second terminal 200 be staggered with those the first terminals 100.Each second terminal 200 comprises one second contact jaw 210 and one second welding ends 220, and wherein second contact jaw 210 inserts connector terminals in order to contact, and second welding ends 220 is in order to be welded in the machine plate.

Consult Fig. 4 and shown in Figure 5, after second terminal 200 that housing 201 links to each other is positioned on the terminal base 300 jointly, housing 201, second terminal 200 and terminal base 300 can be put in the mould of another plastics injection molding once again, to carry out secondary plastics injection molding.After secondary plastics injection molding, can form an embedded block 400, direct forming is one with terminal base 300 and combines on terminal base 300.Generally speaking, terminal base 300 and embedded block 400 are all plastics, and are to adopt different plastic materials.After embedded block 400 was formed, each second terminal 200 was to be embedded in abreast between embedded

block

400 and 300 terminal bases.Embedded block 400 and terminal base 300 stage casing of embedding second terminal 200 partly only wherein makes to second contact jaw 210 and second welding ends 220 of small part to expose to embedded block 400 surfaces.After embedded block 400 was shaped, 201 of housings were removed, to form complete electric connector.

In the electric connector of this creation, those the first terminals 100 and second terminal 200 are all coated by plastic material isolates, only expose contacts such as first contact jaw 110, first welding ends 120, second contact jaw 210 and second welding ends 220, second contact jaw 210 is arranged in first contact jaw, 110 tops, and with first contact jaw 110 be staggered (consulting Fig. 5).

The embedded block 400 of this creation has effects fixing and those second terminals 210 of insulation simultaneously, compared to prior art, this is created ingenious application and coats forming technique, terminal base 300 and embedded block 400 just are coated and fixed on those the first terminals 100 and second terminal 200 wherein when being shaped, do not need earlier with assembling again behind second terminal, 200 coated insulations, and can adopt whole-course automation production, need not assemble cost of labor; Because embedded block 400 direct forming on terminal base 300, need not design embedded block 400 and engage structure with 300 of terminal bases, mold structure is simple, not only reduces manufacturing cost, more improves the processing procedure stability.
