Description

  The present invention relates to a cable connector mounting structure, and more particularly to a cable connector mounting structure that can be mounted in a plurality of directions.

Generally, cable wiring is used for electrical connection between a plurality of electrical components, electrical devices, or electronic devices, and a cable connector is used for this connection.
As the cable connector, an arbitrary pin header is selected depending on the mounting form of the electrical component, the electrical device, or the electronic device, and the wiring routing.
For example, by using a straight pin header 13 having a straight pin 13a as shown in FIG. 7, the housing 12 can be mounted from above the straight pin header 13, and a pin 14a as shown in FIG. By using the angle pin header 14 bent at a predetermined angle, the housing 12 can be mounted from the side of the angle pin header 14.
Patent Document 1 discloses a connector (pin header) including an output terminal (pin) protruding in one direction and an output terminal protruding in a direction orthogonal to the direction.

However, in the conventional cable connector mounting, the mounting direction is limited by the pin header adopted, and the mounting direction can be arbitrarily set by the mounting form, wiring routing, etc. of the electrical component, electrical device or electronic device. There wasn't. In particular, in the case where a common electronic device unit or board is mounted on a plurality of electronic devices having different mounting methods, limiting the mounting direction of the cable connector has hindered common design.
In addition, in the pin header according to Patent Document 1, when changing the mounting direction of the cable connector that is mounted, it is necessary to change the cable from one pin to a pin in a direction orthogonal to the pin, which is easily performed. I couldn't. In addition, since pins are provided in two directions, unused pins are generated, which is uneconomical.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a cable connector mounting structure capable of arbitrarily setting the mounting direction of the cable connector.

In order to achieve the above object, the cable connector mounting structure according to the present invention is formed in a housing in which a pin contact protruding from the pin header and a socket contact attached to the cable are disposed on the top of the pin header.

A double spring member, the double spring member being a contact surface with the pin contact Includes a projecting portion which projects deformation direction of the spring, said pin contact is characterized in that it comprises a plurality of recesses or holes in which the protrusions are inserted alternatively.

  According to the present invention, the pin contact insertion portion of the penetrating portion provided in the housing is a space that is continuous in two directions orthogonal to each other and communicates with the outside of the housing. Since the installation direction of the housing and pin contact is not limited by being able to be inserted into the housing from any direction, the mounting direction can be arbitrarily set according to the mounting form, wiring routing, etc. of the electrical component, electrical device or electronic device. It is possible to realize a cable connector mounting structure that can be used.
