RU1826095C - Electrical socket with zero coupling force - Google Patents

Abstract

The invention relates to the field of microelectronics, in particular, to the design of contact devices, and can be used in the manufacturing process of microassemblies with pin current outputs and for checking them. The electrical contact socket with zero joint force comprises a housing in which a clamp is arranged having a reciprocating movement designed to press the contacts against the pin, two contacts made in the form of elastic plates. One of the contacts is a persistent, having a rectangular working section and a bent upper end for insertion of the microassembly pin, the other contact is movable with a U-shaped curved upper end, allowing it to be softly spring-loaded against the microassembly pin. Both contacts, with their middle parts connected together, form a stop that fixes the contacts from vertical downward movement. Through a rectangular hole in the housing, the lower ends of the contacts exit. The housing has a cover, consisting of a bottom plate having a rectangular window, the walls of which serve as stops for the upper ends of the movable and thrust contacts, while simultaneously securing them from lateral movement, and an upper plate that restricts the movement of contacts up and has a round hole for the passage of the microassembly pin .3 ill.

Description

The invention relates to the field of microelectronics, in particular to the design of contact devices, and can be used in the technological process of manufacturing microassemblies with pin current leads and for checking them.

The purpose of the invention is to improve the reliability of contacting.

Comparative analysis with the prototype shows that the plug-in electrical contact socket with zero joint force differs in the form of contact design, which allows, due to the presence of a guaranteed gap, to freely insert the microassembly pin into the socket, not

damaging the glass insulators and making contact with the pin along two lines, is also distinguished by the presence of a clamp, which carries out pressing, passing through its rectangular window of contacts to the pin,

the lower 3 and upper 4 plates, while in the lower plate 3 a rectangular window 5 is made, and in the upper plate 4 there is a hole 2 for inserting pin b, a movable contact 7 made with a curved U-shaped upper end 8, s a rectangular section 9 and a curved section in the middle part 10, and an elastic contact 11 with a bent upper end having a rectangular working section 12 and a curved section 13 in the middle part, while contacts 7 and 11 abut against the inside with their curved sections 10 and 13 the surface 14 of the housing 1 (Fig.Z), and their upper ends 8 and 15 are placed in a rectangular window 5 of the lower plate 3. The device comprises a clamping element 16 mounted on the movable contact 7 between the housing 1 and the lower plate 3 with the possibility of reciprocating motion.

The electrical socket works as follows. The pin 6 (Fig. 3) of the microassembly is freely, effortlessly inserted through the hole 2 in the upper plate 4 of the housing cover 1 into the socket and slides along the elastic contact 11. There is a guaranteed gap between the contacts 7 and 11. The clamping element 16, translationally moving, clamps the pin 6 between the contacts 7 and 11. Contacting occurs along two lines along the length of the pin. The constancy and reliability of the electrical contact is ensured by the elasticity of the movable contact 7.

The proposed electrical contact socket with zero effort of articulation with its contact form and the presence of a guaranteed gap between them allows freely, without effort to be inserted into

the socket is the pin of the microassembly, thereby ensuring the safety of the glass isolator.

Contacting takes place along two lines with a soft spring-loaded pin clamping between the contacts by clamping, which increases the reliability of contacting.
