Description

The rivet spare that a kind of interface device is used

Technical field

The utility model relates to the various DIU data interface units on a kind of computer system or other electronic equipment, particularly is arranged at the rivet spare on such interface device.

Background technique

Various DIU data interface units on computer system or other electronic equipment, as serial line interface (as serial port COM1 and COM2) on the computer main board, parallel interface (as the LPT printing interface), VGA interface or the like is set, generally by interior insulating base, interface block, the bolt that some conduction copper cash pins are housed, be the fixed plate of letter ' Z ' shape and connect rivet and constitute.The various interface device is welded on the circuit board by the fixed plate that is provided with thereon.As shown in Figure 7, existing fixed sheet 10 be connected rivet 20 in when assembling, to connect rivet 20 earlier is through in the through hole 101 that fixed plate 10 tops have, then fixed plate 10 is fit in the slotted eye that insulating base is provided with connecting rivet 20, and will connects rivet 20 by press machine and be stamped in the perforation of making on the interface block and fix.Whole assembly process is very cumbersome, the length that expends time in, thus cause the efficient of interface processing and fabricating low, the cost of production height.And, because fixed plate 10, connection rivet 20 adopt two individual components to constitute, constitute by rivet body 201 and tapped meson 202 2 parts and connect rivet 20, thereby make that a whole set of fixed component material consumption is more, working machine requires high and processes very cumbersome, fabricating cost is very high, causes product to be difficult to survive in the fierce market environment.

The model utility content

The purpose of this utility model is to solve above-mentioned existing problems, and a kind of interface device assembly process that helps simplifying is provided, and reduces work hours and expends, enhance productivity, and help saving raw material, reduce enterprise's cost of production, the rivet spare that interface device simple in structure is used.

The technical solution of the utility model is achieved in that

The rivet spare that a kind of interface device is used, its characteristics are to comprise connecting pin and rivet sheet, and wherein the top of connecting pin and rivet sheet is connected as a single entity, and the rivet sheet is provided with the screw that has internal thread that is connected with connecting pin.

Wherein, above-mentioned rivet sheet is made of riser that plays the meson effect and the rivet pin that plays fixation, and integral body is bent into and is letter ' Z ' shape, and above-mentioned connecting pin and riser are connected as a single entity.

For interface device can be fixed on the circuit board more reliably, the rivet pin of above-mentioned rivet sheet becomes the fastening foot that is the harpoon shape.

The utility model is owing to the structure that adopts being made of one of rivet spare, make the utility model when carrying out the interface device assembling, only need be placed on rivet spare on the interface device, press with press machine once just rivet spare to be assemblied on the interface device reliably the assembly process of finishing.Not only simplified rivet spare assembly process, reduced work hours and expend, greatly improved interface device in processing efficient, and reasonable in design, compare with original rivet assembly, can save raw material widely, reduce the production and operation cost of enterprise, improved the competitiveness of product in market.

Below in conjunction with accompanying drawing the utility model is further described:

Embodiment

As Fig. 1, shown in Figure 8, the utility model also comprises and constitutes the insulating base 4 that is used to install electrical signal transmission wiring pin that an interface device possessed, trapezoidal mouthful plug socket 5 and bolt 6 etc., because this part technology all is present common technique structure, so be not described in detail at this.For cumbersome, consuming time many, manufacturing efficiency is low, cost of production the is high problem of the assembly process that solves existing interface device that rivet spare causes, extremely shown in Figure 7 as Fig. 2, rivet spare described in the utility model comprises connecting pin 1 and rivet sheet 2, wherein connecting pin 1 is connected as a single entity with the top of rivet sheet 2, and rivet sheet 2 is provided with the screw that has internal thread 3 that is connected with connecting pin 1.Wherein, described rivet sheet 2 is made of riser 21 that plays the meson effect and the rivet pin 22 that plays fixation, and integral body is bent into and is letter ' Z ' shape, and described connecting pin 1 is connected as a single entity with riser 21.For interface device can be fixed on the circuit board more reliably, the rivet pin 22 of described rivet sheet 2 becomes the fastening foot that is the harpoon shape.Simultaneously, use for the utility model can be suitable on various types of interface devices, become the part of wildcard type, as Fig. 2, Fig. 4, Fig. 5 and shown in Figure 7, described connecting pin 1 becomes the bearing pin of cylindrical shape, and it also is provided with a scrobicular ring 11 near on the surface of riser 21 ends.Meanwhile, for convenient bolt 6 spinnings are gone in the screw 3, as Fig. 4 and shown in Figure 7, described screw 3 becomes the internal diameter of the internal diameter of bolt entry end greater than outlet end, and is provided with internal thread 31 at the inwall of outlet end.As shown in Figure 1, make the utility model when carrying out the interface device assembling, only need be placed on rivet spare on the slotted eye that insulating base 4 is provided with, connecting pin 1 is aimed at the perforation 51 that plug socket 5 two sides are provided with, with the press machine pressure connecting pin 1 is combined closely with the perforation 51 of plug socket 5, thereby rivet spare is assemblied on the interface device reliably, finishes the assembly process of rivet spare.And then the threaded end of bolt 6 is screwed in the screw 3 of connecting pin 1, promptly finish the whole assembly process of interface device.When assembling, can be as shown in Figure 6.Not only simplified rivet spare assembly process, reduced work hours and expend, greatly improved interface device in processing efficient, and reasonable in design, compare with original rivet assembly, can save raw material widely, reduce the production and operation cost of enterprise, improved the competitiveness of product in market.Simultaneously, for the needs that use on the interface device that satisfies different model,, the length of two kinds of intermediate portions can be reached the size rivet spare different with height of stretching diameter, so that it can satisfy the needs of various application as Fig. 2 and shown in Figure 5.
