Description

The computer connector terminal

A kind of computer connector terminal relates to computer connector.

As Fig. 1, shown in 2, known computer connected device 5,5 ', with number row terminal 61,71 plant one have perforation 511,511 ' back terminal base 51,51 ' with have class and bore a hole 521,521 ' front end stroma 52,52 ' between, in it, stick with terminal 61,71 after, cover back terminal base 51,5r and front end stroma 52,52 ', again via back casing 53,53 ' with procapsid 54, riveted is fixed behind 54 ' mutually enclosures, and the terminal structure 61 that the terminal that Fig. 1 adopts system forms with sheet material punching out side by side, and the terminal 71 that Fig. 2 adopted is the structure with the processing of lathe one Zhi Zhiche system, there are many defectives in these two kinds of terminals 61,71:

1. cut out the terminal of more than of the systems of loosing owing to lathe, during plated metal, must electroplate, can't form plated material and expend, electroplating cost is increased singly with regard to the dizzy electroplating of leading section of terminal for grafting to whole Zhi Duanzi.

2. can prune during turning forms the part material of terminal, produces the car bits, removes when costing, and increases and use real cost.

3. can form the car line on the terminal of turning moulding, in the grafting contact-making surface, leave bigger space, increase resistive impedance.

4. insulation distance was near excessively between its maximum tiltedly encircled 711 between two abutting end, so the situation of electromagnetic wave magnetic interference (surging, noise, the output of conduction signal weaken or the like) is comparatively serious.

5. terminal inserts front end stroma and back terminal base respectively, because of accuracy tolerance more easily causes loosening.

6. palpus upper end stroma cooperates its structure with the lower end stroma and installs, and can't can finish assembling with single terminal base, so the die cost expense is increased.

7. because it is indivedual systems of loosing, be, can't reach the production automation with production process.

8. because terminal ends forms circular hole welding, but circular hole and be not suitable for the scolder filling deeply, the air in the hole is difficult for circulation, forms gas and is filled in the face of cohering, and makes the solder side loose contact, is difficult to welding.

With regard to the terminal of Fig. 1, wherein, each terminal 61 all is connected punching out side by side with rear end lath 62 and constitutes again, and 61 structures of dashing volume as a kind of hollow of terminal, can partly improve the disappearance of above-mentioned terminal 71, and it is gold-plated to be convenient to the segmentation selectivity, yet still can causes following disappearance:

1. because of its anterior insert end also is a hollow structure, intensity is very poor, if the butt joint of connector is uncertain, or overexert, and askew connecing, the situation that often has disconnecting occurs.

2. because of inserted terminal is that punching out is rolled into circle, its out of roundness is not good, so the friction when pegging graft is big, attains and makes the lost of life.

3. because out of roundness is not good, follow that to have contact fruit bad, the disappearance that resistance value is bigger.

4. its terminal 61 structures still must cooperate the front end stroma 52 with perforation 511 to assemble with the back terminal base 52 in tool class hole 521, and it is a lot of that die cost is improved.

5. terminal structure 6 still has the bigger disappearance of tolerance at fit on.

6. though its end has formed flat horizontal surface of expansion, the position of supply lines welding is still dull inadequately, makes electric wire be difficult for welding.

The purpose of this utility model is to provide a kind of certain out of roundness that has, and frictional force is little when patching, and can not increase electrical impedance, is easy to parcel plating, lower-cost computer connector terminal.

The utility model is to realize like this, the computer connector terminal, by the compression moulding of one section filled circles wire rod, one end of filled circles wire rod directly forms the terminal front end, the other end forms terminal ends, terminal ends forms the weldering cup of welding electric wire, this appropriate position, wire rod posterior segment, local compression becomes the fixed part of flat expansion, the fixed part system of terminal is pressed into section with the four angular direction application of forces and is criss-cross shaft of rib, this shaft of rib also forms rearward oblique outward rim, make the fixed part end outside be wedge angle, and multiple compacting one downwards is so that increase the swash plate of welding volume in the weldering cup of terminal ends, the sealing of the ventilation usefulness of bottom when scolder is accepted in formation one superfine little confession between ora terminalis and weldering cup under this swash plate.

In addition, the preceding appropriate position of terminal fixed part, the local hand-held portion of restraining that extrudes flat expansion, this rearward oblique outward rim of hand-held portion of restraining, the terminal outside is wedge angle and protrudes.

The utility model of said structure has following superiority:

1. because terminal is formed by the compacting of filled circles wire rod, and not only intensity is bigger, and out of roundness can be very accurate, making it patch Shi Buhui increases friction, causes electrical impedance to increase;

2. owing to appropriate position, posterior segment at terminal, local compression becomes the fixed part of flat expansion, this fixed part forms the rib limit with wedge angle, produce to collude in the time of in inserting terminal hole and fasten, terminal base need not be divided into front end stroma and back terminal base, make the terminal base unification, reduced the die sinking cost of terminal base;

3. several terminals can be folded in one and have on the chain band of several terminal holders, can be by the sub-front and back end of chain band spaced ends, thereby the terminal front end of the mill cover that helps pegging graft selection gold-plated, need not wholely electroplate, saved the plating material, reduced cost;

4. because the distance between the sub-fixed part of two abutting ends in the terminal base, be greatly than the distance of the oblique interannular of existing two-terminal, so be difficult for that the interference of electromagnetic field is arranged, the telecommunication signal is stablized;

5. owing to terminal ends forms flat arc weldering cup, this flat arc weldering cup suppresses a swash plate downwards again, makes the position of flat weldering cup supply lines welding more dull, makes electric wire have bigger space to weld.
