Problems solved by technology

However, as described above, the upper part of the planar adsorption area must be set not to be covered by the leaf spring. Therefore, not only the planar adsorption area cannot be formed near the center of gravity, but also the planar adsorption area cannot be formed in the vertical direction with the leaf spring. Overlapping positions, therefore, the projected area to the circuit board increases, which becomes an obstacle to high-density mounting of the circuit board

Abstract

The present invention relates to a terminal for connecting a circuit board. Its object is to provide a circuit board connection terminal that does not change the height of the contact portion of the leaf spring on the circuit board, does not cover the contact portion with solder flux, and can obtain reliable connection to an external conductor. Between the base plate part of the cantilever supporting the leaf spring elastically contacting the external conductor and the soldered connection part, a foot part is formed to support the base plate part in parallel above the circuit board at a set interval, so that the plate The free end side of the reed protrudes from between the base plate portion and the circuit board. The leaf spring is supported at a high position away from the soldered connection, so it will not be covered with flux.

Description

Technical field [0001] The present invention relates to a terminal for connecting a circuit board. A solder connection portion is soldered to a conductive pattern of the circuit board and mounted on the circuit board, so that the conductive pattern of the circuit board is electrically connected to external conductors such as a surrounding shielding plate. ,It relates to a circuit board connection terminal provided with a U-shaped leaf spring that is elastically contacted with an external conductor. Background technique [0002] Various circuit board connection terminals that connect the ground pattern of the printed wiring board to the surrounding shield plate to short-circuit the ground terminal, etc., so that the conductive pattern of the circuit board mounted on the circuit board is electrically connected to the external conductor Known by people. Conventionally, the circuit board connection terminal mounted on the circuit board in this way makes the leaf spring with the spri...
