Subminiature signal relay

Abstract

The invention discloses a subminiature signal relay. The subminiature signal relay comprises a shell and a plastic body accommodated in the shell and used for integrally injecting a static spring anda coil, the side walls, corresponding to the two sides of the axis of the coil, of the plastic body extend out of an internal insert and are bent downwards to be attached to the corresponding side walls to be provided with a plurality of leading-out ends. Among the multiple leading-out terminals, protruding structures which can be matched with the inner side wall of the shell and are formed by cutting are arranged on the leading-out terminals corresponding to the edges of the two ends of the axis of the coil and on one sides of the outer sides of the widths of the leading-out terminals in an outward protruding and extending mode, and the tail ends of the protruding structures are in an arc shape. On the premise of not increasing the volume of the relay, the inclined leading-out terminals can be automatically guided, so that the leading-out terminals are ensured to meet the requirement of verticality or position precision, and the process of adjusting the verticality or position precision of the leading-out terminals is simplified.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to an ultra-small signal relay applied in the high-frequency field. Background technique [0002] In the existing ultra-small relays, the cut static spring is usually integrated with the coil and base through injection molding, and the lead-out end of the static spring and the lead-out end of the coil are formed by bending the cut pieces after injection molding. The outlets of this ultra-small relay are usually distributed along both sides of the coil axis; after these outlets are bent, their verticality will have a certain deviation. That is to say, the lead-out end located in the middle position can be limited by the stop walls corresponding to the two sides of the lead-out end position formed by the injection molding body to prevent the lead-out end from skewing, and it is located at the side position (that is, the edge position corresponding to the two ends of the coil axis) Due...

Problems solved by technology

Generally, simulation calculation is used to design the characteristic impedance, but because of the error of simulation calculation and part processing, the actual characteristic impedance will have a certain deviation. At present, the high requirements for mold processing are generally used to reduce the deviation, and the technical difficulty and cost are high.
