Description

Improved connector end strip of integrated circuit

The utility model relates to a kind of improvement of integrated circuit connector dististyle, its particular design can make dististyle except that saving material cost and reduce the relativity error on making, simultaneously the time with the connector actual assembled, more because its integrated novel modeling structure, and reach easy to assembly, quick and reliable and stable remarkable result.

General integrated circuit connector mainly is made up of connector body and the terminal that is the matrix double-row type.Traditional integrated circuit connector, the package assembly of itself and dististyle as shown in Figure 6, wherein, the dististyle that is assembled on connector body (1a) round (11a) mainly is to be made of preceding dististyle (2a) and back dististyle (3a), because forward and backward dististyle (2a) is the difference in the moulding (3a), therefore both form with two groups of die stampings respectively, with its form of arranging in pairs or groups each other, are assembled in and form the double-row type terminal structure when body (1a) round (11a) is gone up; As for before this, back dististyle (2a) modeling structure (3a), as shown in FIG., both are by being positioned at the crooked row's hook (21a) in below (31a), row's hook (21a) (31a) top protracts upright terminal (22a) (32a) and be positioned at (32a) top of terminal (22a), with terminal (22a) (32a) the strip tabs (23a) that links to each other of one (33a) constitute, yet both difference, except that terminal (22a) (32a) castor from difference, the terminal (22a) of dististyle (2a) is protracting back and be an oblique angle and after can being assembled in body (1a) with the terminal (32a) of back dististyle (3a) simultaneously, and is preceding, back dististyle (2a) terminal (22a) (3a) (32a) forms biserial form side by side; At last, then need will this forward and backward dististyle (2a) tabs (23a) (3a) (33a) respectively from (32a) fractureing with manual type and separate (as Fig. 7) in the junction with terminal (22a), cooperate again one locate cover plate (3) thus finish the assembling (as Fig. 1) of this connector.

The modeling structure of the before connector dististyle that has, because to the greatest extent in desirable and have following some deficiencies at least, cause connector integral body problem such as uneconomical and impracticable in processing and material use:

1. loaded down with trivial details, the waste material increase of operation: because the forward and backward dististyle (2a) that dististyle comprised that has earlier (3a) is formed by two groups of die stampings respectively, and also need imposing two procedures respectively, the dististyle of punching press after finishing just finish plating, therefore, in each course of processing, all must comprise two procedures loaded down with trivial detailsly, and connector integral production cost is increased; In addition, for making (31a) interlaced slotting the standing on the round (11a) of connector body (1a) of energy of forward and backward dististyle (2a) row's hook (21a) (3a), therefore, forward and backward dististyle (2a) (3a) in punching press simultaneously, need to cooperate row's hook (21a) spacer knobs (31a) apart from and strengthen nearly one space, thereby waste lot of materials.

2. biplate punching press, error increase: because the forward and backward dististyle (2a) that has earlier is (3a) respectively by two groups of die stamping moulding, and (3a) need cooperatively interact in addition and be assembled in round (11a) on the connector body (1a) through the forward and backward dististyle (2a) after the forming processes, therefore, if with two groups of die stamping moulding, easily because of the error on the stamped, and make front and back ends (2a) (3a) be difficult to be used, and the incidence of relativity error is greatly improved.

3. biplate dististyle, assembling are difficult for: because the connector dististyle that has earlier (3a) is made up of forward and backward dististyle (2a), therefore when assembling with connector body (1a), except that needing to finish the monolateral grafting of body (1a) with forward and backward two procedures, simultaneously, after the dististyle grafting is finished, also need tabs (23a) when (33a) fractureing, if four sides that possessed with body (1a) calculate, then need impose totally eight times the operation that fractures, increase the loaded down with trivial details property of assembling and have a strong impact on efficient; Secondly; since this have earlier tabs (23a) design (33a) be one in succession in terminal (22a) top (32a), and its area seems very little because of strip restriction, so; usually also need engagement tool to finish when fractureing operation, therefore operation is convenient inadequately.

4. tabs is long, easily cause short circuit: because before, back dististyle (2a) (3a) is respectively arranged the pitch of hook (21a) between (31a) to be increased, tabs (23a) length (33a) is increased in the punch forming process relatively, yet long tabs (23a) is (33a) easily because of falling into connector body (1a) (32a) formed central space of terminal (22a) all around accidentally after fractureing, be difficult to pick up and be subject to terminal (22a) projection (32a), test and when quality management is neglected, make finished product, and then may cause signal short circuit sintering phenomenon, cause defective products to increase.

Main purpose of the present utility model is to utilize the design of one chip, and is stamped to form with single mold, makes one-body moldedly on the dististyle to go out biserial terminal, row's hook and back strip tabs etc. side by side, thereby has solved the existing some problems of prior art; Its advantage comprises:

1. single manufacturing procedure is simplified the dististyle punch forming to the flow process of making assembling, simultaneously, because with the punch forming of monolithic strip, therefore, each is arranged and need not to keep staggered spacing between the hook, therefore, than the use that can significantly reduce material that has earlier, thereby save manufacturing cost up to nearly 50%.

2. because with monolithic strip, single mold punch forming, thus can greatly reduce in the foozle rate, and do not have the problem of the double-disk dististyle relativity error that has earlier.

3. be the design of one chip dististyle because of it, therefore when being assembled in connector body, each monolaterally only has one folding piece body, and reduces the required number of times that fractures of each connector body, can effectively increase efficient, simultaneously, full chip designs because tabs is a large tracts of land, therefore, can reach the simple and easy effect that fractures under not by other instrument situations, reduce operation and go up puzzlement, can effectively improve quantum of output simultaneously.

4. owing to adopt the one chip design, therefore in punching course, because pitch shortens between each row's hook, therefore the tabs of being retained also thereby shorten, even so in tabs fractures process, fall into body terminal central authorities all around accidentally, also, make it to be easy to drop out between terminal because of its unlikely clip is difficult to pick up between terminal, and the generation of minimizing finished product fraction defective.
