Abstract

A METHOD OF MANUFACTURING CONTACT ELEMENTS, including you from a ribbon blank, unwrapping contact elements, shaping them, separating contact elements from the workpiece, electroplating and assembling contact elements with an insulator, characterized in that, in order to improve performance, electroplating is applied to the contact the elements are carried out before their shaping, and the separation of the contact elements from the workpiece is carried out after the installation of the contact elements in the isolate ore, d SL

Description

The invention relates to the manufacture of electrical contact devices and can 6FjTb used in the manufacture of electrical connections in the manufacture of whole-shaped double-sided (forked) elastic contact elements. A known method of manufacturing contact elements on sequential dies with further processing on operational dies. Electroplating of the entire surface is carried out on drum-type installations, and separate areas are dipped by dipping, for which it is necessary to fix each part separately on a special transport device. The method is common in production because of the simplicity of the technical solution, but it has a small degree automation and poor performance. Closest to the proposed by the technical entity method of manufacturing contact elements, including cutting: from the band blank, scanning the contact elements, shaping them, separating the contact elements from the workpiece, electroplating and assembling the contact elements with an insulator 2j. When covering the contact separated from the tape, it is necessary to fix it on the transport fixture of the electrolysis bath, while the place of contact of the contact with the fixture remains unaffected. Piece fixing compact parts of complex shape is a time consuming operation. The use of rotating drums, loosely filled with dates, is unacceptable due to the formation of packages of parts and the distortion of their shape during processing. Contact forms can be made preferably from corrosion-resistant materials that do not require complete coating with precious metals, but this reduces the range of use of less constructive contact materials, such as nickel silver, brass, etc. The disadvantage of this method is also the single-piece assembly of contacts with an insulator, which is a time-consuming manual operation. The purpose of the invention is to increase the productivity. This goal is achieved by the fact that according to the method of manufacturing contact elements, including cutting out of the ribbon blank, the scanning of contact elements, their formation, separation of contact elements from the blocking, electroplating and assembly. contact elements with an insulator, electroplating is applied to the contact elements before shaping them, and the separation of the contact elements from the workpiece is carried out after the contact elements are installed in the insulator. 1 shows a contact element; in Fig. 2, view A in Fig. 1; Fig. 3 is a flow chart of preliminary mechanical processing of the contact group; 4 shows a contact group after preliminary machining; fig. 3 - the same (final machining); on fig.b - the same (before assembly with an insulator) ,; in fig. 7 - the same (the moment of assembly with an insulator, a longitudinal section); on Fig - section BB in Fig. 7., The contact element (figure 1) consists of elastic contact .. petals 1 box 2, the working area with curved ends 3, the shank 4 and the protrusion 5. Contact elements are combined in contact groups (fig. b) and connected to the workpiece 6 by means of a technological jumper 7. The number, contact elements and their mutual arrangement correspond to a number of nests (holes) in insulator 8 (Fig.7). The proposed method for the manufacture of contacts consists of the following actions: preliminary mechanical processing, including the cutting of petals from a ribbon and the punching of technological holes, the molding and bending of petals, as well as the cutting of the shank, lintel and contour of the box; division of a tape into contact groups -. py; galvanic treatment; final machining, including the separation of the shank, the shaping of the box, the calibration of the box and the reorientation of the contact; insulated assembly; separation of contacts from tape. When pre-processing contacts (fig.Z) in the workpiece 6, the punch 9 pierces the fixing hole 10 and the punches 11 and 12 cut out the contours of the petals 13. At the subsequent punching steps, in the zone 14, the molding of the petals 1 is formed and beaten, the cutting of the contour, the box 2 and the stem 4 punches 15 and 16. The accuracy of feeding the tape in the punching step is provided by catchers 17. Then, the strip blank 6 is divided into contact groups (Fig. 4) along line 18. (Fig. 3). The body 2 of the contact with: the workpiece 6 is connected through the shank 4 and the technological bridge 7, which provides rigidity during transportation and during electroplating

processing. The operations are performed on a special punching machine, the productivity of which is designed for 90 contacts per minute.

To perform the galvanic processing operation, the contact group (Fig. 4) is fixed to a transport device (not shown) using openings 10, which allows adjusting the coverage area by changing the depth of the contact group in the electrolysis bath. The contacting group of the contact group with silver or nickel is carried out by immersion in the electrolyte up to line 19, and the gold coating by immersion of the contact petals is only in the zone of the bent ends 3 (Fig. 1), which results in saving precious metals. Fixing the contact group on the transport device according to the proposed method improves the performance of auxiliary operations of fixing and removing, as well as ensures that all surfaces are covered. Details, as the fixing elements are separated from the contact design.

After the electroplating operation, the contact group undergoes final machining (Fig. 5), consisting of separating the shank 4 from the workpiece 6 using the punch 20, shaping the contact box in zone 21, calibrating the box to zones 22, and reorienting the contact in zone 23. The reorientation consists of rotating the contact element relative to the workpiece 6 according to the location of the sockets B of the insulator 8 (Fig. 6).

When turning, the technological jumper 7 (figure 5) is deformed (twisted) in close proximity to the protrusion 5, where the smallest cross section is structurally formed.

The final machining operations are performed on a special punching semi-automatic machine with a productivity of 60 parts per minute.

The assembly of the contacts (Fig. 7) with the insulator 9 takes place prior to their separation from the blanks 6. The depth of the lowering of the box 2 of the contact element to the socket 24 of the insulator 8 is provided by a mounting device (not shown).

After the assembly of the contact group (Fig. 6) with the insulator 8 (Fig. 8), the workpiece 6 is separated from the contacts by breaking it off, for which the workpiece 6 is bent to the side. The separation occurs in the area of the protrusion 5, the cross-section of which is relaxed by reorientation (rotation) of the contact during the final machining

Compared with the prototype, the proposed method provides higher performance due to the failure of the single-piece contacting of the contacts on the transport device during galvanic processing, as well as the failure of the single-piece assembly of contacts with an insulator with the transition to batch processing.
