Switch-equipped coaxial connector

Abstract

With a simple configuration, increase in size can be avoided, usage durability is improved, and occurrence of insufficient electrical connection caused by dust can be prevented well. A crank part 12a3 is provided in at least one of both contacts 12 and 13 including elastic beam-like members 12a and 13a. Both of the contacts 12 and 13 are provided with cut-away parts 12d and 13d, which substantially increase the span lengths of the elastic beam-like members 12a and 13a, and gaps S1 and S2 between the contacts 12 ands 13 and an insulating housing 11 which ensure flexibility of the elastic beam-like members 12a and 13a to ensure flexibility and prevent permanent deformation of the contacts while enhancing elasticity of the contacts 12 and 13. Dust which has entered the interior thereof is moved along the crank part 12a3 to ensure electrical conductivity well, which is an employed configuration.

Description

technical field [0001] The present invention relates to a coaxial connector with a switch including a pair of contacts separated by mating with a mating connector. Background technique [0002] Generally, a coaxial connector with a switch is used in electronic or electric equipment such as mobile phones. This coaxial connector with switch is used, for example, as a small-sized circuit inspection switch for inspecting the state and performance of various electronic circuits such as high-frequency circuits provided in equipment, but is disclosed in the following Patent Documents 1 and 2, etc. The circuit inspection switch is composed of a coaxial connector with a switch mounted on the circuit board in such a way as to break the electronic circuit of the main body of the equipment. The target insertion hole of the coaxial connector with switch is inserted from the upper side to the inside. [0003] In such a coaxial connector with a switch, a conductive housing for ground con...

AI Technical Summary

Problems solved by technology

[0005] However, in such conventional coaxial connectors with switches, the contacts may be permanently deformed due to repeated insertion of the probes (inspection pins) of the inspection plug connector, and there is a problem in durability.

In order to improve the durability of use, it is also considered to increase the elasticity by increasing the span of the contact. However, by simply increasing the contact, the overall size of the connector will increase, which is contrary to the requirements of miniaturization and flattening in recent years.

In addition, dust such as tiny foreign objects and insulators that exist in the operating atmosphere enters the interior through the insertion hole of the probe (inspection pin) of the inspection plug connector, and there is also a problem that electrical connection failure may occur.
