Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a short-circuit socket connector that can connect the first and second mating pins to each other or hold them in an unconnected state. It is.

"Prior art" For example, first and second
A short-circuit socket connector has been conventionally used, which is configured such that a mating connection pin can be inserted into the connector, and is attached to the mating connection pin to connect the first and second mating connection pins.

The conventionally used short-circuit socket connector is
It only had the function of connecting the first and second mating connecting pins inserted through the short-circuiting insertion hole formed in the housing of the connector.

FIG. 4 shows the configuration of the main parts of this type of short-circuiting socket connector that has been used conventionally. The pin 3 is configured to be inserted and mounted. A clamping body 4 made of a conductive material is housed in the housing 1, and a clamping piece 5 formed on the clamping body 4
The first and second mating connection pins 3 inserted from the insertion holes 2 between -1 and 5-2 and between 5-3 and 5-4 are elastically held.

Therefore, the first
When connecting the second mating connecting pins to each other, the first and second mating connecting pins are respectively inserted into the shorting insertion holes 2 of the shorting socket connector.
By this insertion, the first and second mating connection pins can be connected, and the circuits of the circuit board connected to these first and second mating connection pins can have a predetermined circuit configuration. However, in order to maintain the connection between the first and second mating connection pins in an open state, separate electrical components must be used for holding the first and second mating connection pins. When various types of connectors are attached to mating connection pins in this way, the mounting space on the circuit board becomes large, which impedes high-density mounting.

Furthermore, in the conventionally used short-circuit socket connector shown in FIG. 4, the socket contacts are formed by simple punching, so that the fitting length of the mating connecting pin to be attached is limited. For this reason, it is necessary to make the shapes of the short-circuit socket connectors different depending on the protruding length of the mating connection pins protruding from the circuit board.

Therefore, it is necessary to create many types of short-circuiting socket connectors, and select one suitable for the pin length of the mating connection pin from among these to use, and installation is not easy.

``Problems to be solved by the invention'' This invention solves the problems in the conventionally used short-circuit socket connectors, and
It can be used to connect the first and second mating connection pins, and to hold the first and second mating connection pins open. The present invention provides a commonly usable short-circuit socket connector.
