Coaxial connector with switch

Abstract

The present invention relates to a coaxial connector with a switch. An aim of the invention is to configure the terminals in a housing without wastage for realizing low profile and small size. The terminal at one side is simplified without interference to a spring forming area of a terminal at the other side thereby obtaining higher insulativity. An upper part of the housing is composed of a cylinder part which is provided with a pin insertion hole through an insertion mode, and the lower part is composed of a projection which is internally provided with a movable clearance part that is communicated with the pin insertion hole. Terminal pressing-in grooves which extend in a direction that is approximately same with an insertion-extraction direction of a touch pin are formed from two sides of the projection to a movable clearance part. The pressing-in parts for fixing each terminal are pressed in the terminal pressing-in grooves. The movable clearance part is formed larger than the pin insertion hole. One terminal pressing-in groove is formed from one side surface of the housing to a position which is in the movable clearance part and is staggered from the pin insertion hole, and the other terminal pressing-in groove is formed from anther side surface of the housing to a position which is provided in the movable clearance part at the other side of the former terminal pressing-in groove and is staggered from the pin insertion hole.

Description

technical field [0001] The present invention relates to a switch-attached coaxial connector, which is a connector built into small electronic devices such as cellular phones, and which can realize miniaturization and low profile and obtain stable characteristics. Background technique [0002] Figure 5 and Figure 6 Shown is a conventional coaxial connector with switch 10 (see Patent Documents 1 and 2). [0003] In these figures, the switch-attached coaxial connector 10 is extremely small in size, with a diameter of about 2mm, and includes: a shell 13 made of insulating material, a shell 14 made of conductive metal, a normally closed terminal 15 and a general terminal 16. [0004] The upper half of the above-mentioned case 13 is a cylindrical portion 17, and a pin insertion hole 17a is pierced in the center. In addition, in the lower half of the housing 13, one terminal supporting protrusion 18 and the other terminal supporting protrusion 20 protrude outward at intervals ...

AI Technical Summary

Problems solved by technology

[0014] (1) The spring portion 32 of the common terminal 16 is formed in a transverse U-shape, thus causing the distance from the pressing portion 39 to the bottom of the spring portion 32 to become longer, and the height of the connector 10 with the switch to be correspondingly higher, thereby hindering miniaturization

In addition, when the common terminal 16 is fixed to the case 13, it is necessary to maintain the external force applied from the contact pin 35 to the pressing part 39 of the common terminal 16 by the edge part 33b of the horizontal fixing part 33 and the press-fit support protrusion 33a. Therefore, the length of the fixed part 33 that fits with the terminal press-fit part 21 of the housing 13 and is used to resist external stress must be set sufficiently large, so it is difficult to reduce the size of the fixed part 33 and realize the miniaturization of the overall shape

[0015] (2) Since the distance between the spring part 32 of the common terminal 16 and the contact part 30 is relatively close, the stroke of the contact pin 35 needs to be set relatively large, which is the same as (1), which hinders the realization of miniaturization

[0016] (3) The front end of the spring portion 32 of the common terminal 16 is fitted in a gap with the escape hole 38 of the normally closed terminal 15 and folded back to be loaded, so the front end of the spring portion 32 of the common terminal 16 is close to the escape hole 38 of the normally closed terminal 15, High insulation cannot be obtained

[0017] (4) The contact portion 27 of the normally closed terminal 15 , the contact portion 31 of the common terminal 16 , the pressing portion 39 and the spring portion 32 are arranged in a straight line along the insertion direction of the contact pin 35 of the detector 11 , so inside the cylindrical portion 17 There is an offset in the configuration of the terminals, which hinders the realization of miniaturization
