the lower rubber core 50 is mounted below the fixed terminal 30 and the movable terminal 40 through the latch 13, and includes: the upper surface of the lower rubber core body 52 is provided with a recessed cavity 51, a static terminal welding part leading-out opening 53 arranged at the rear end of the lower rubber core body 52, a moving terminal welding part leading-out opening 54 arranged at the front end of the lower rubber core body 52, a static terminal fixing boss 55 arranged at the position of the recessed cavity 51 close to the static terminal welding part leading-out opening 53 and aligned with the static terminal fixing part 31, an accommodating boss 57 arranged in the recessed cavity 51 and enclosing with the side wall of the lower rubber core body to form a supporting accommodating space 56, and a locking groove 58 arranged at the lower surface of the lower rubber core body 52 and matched with the locking part 13; the movable terminal supporting portion 46 is located in the supporting and accommodating space 56 and contacts with the lower rubber core main body 52 at the bottom of the recessed cavity 51.
By way of example, the socket 12 extends upward along the housing body 11 and has a top flush with the top of the mating opening 22. Specifically, the housing 10 is made of metal. The effect of external electromagnetic interference on the coaxial switch is shielded by a metal shell in this example by designing the top of the socket 12 to be flush with the top of the opposite plug opening 22 so that the socket 12 completely covers the opposite plug switch 22.
As an example, as shown in fig. 1, the latch 13 includes: locate casing main part 11 both sides and downwardly extending's connecting piece 131, and locate connecting piece 131 keeps away from casing main part 11 one end and with the latch 132 of latch groove 58 shape adaptation. The locking function of the whole coaxial switch is realized by tightly buckling the locking piece 132 in the locking groove 58; meanwhile, when the locking member 132 is fastened to the locking groove 58, the housing 10 provides an upward supporting force to the lower rubber core 50, so that the elastic pressing force between the movable terminal 40 and the fixed terminal 30 is further increased by increasing the interaction force between the movable terminal supporting portion 46 and the lower rubber core 50.

In practical applications, in order to increase the tightness of the movable terminal 40 installed in the movable terminal positioning portion 24, the width of the limiting space 242 should be equal to the width of the movable terminal limiting portion 43; in operation, the width of the limiting space 242 may be slightly larger than the width of the movable terminal limiting portion 43 for easy installation.
As an example, as shown in fig. 4, the stationary terminal contact part 33 has an inverted V-shaped structure, so that the stationary terminal contact part 33 is reliably contacted with the movable terminal contact part 45; at this time, as shown in fig. 5, the movable terminal contact portion 45 includes: a first movable terminal contact arm 451 and a second movable terminal contact arm 452 which are respectively in contact with two side walls of the inverted-V structure; the moving terminal support portion 46 includes: a first supporting spring 461 connected to the first moving terminal contact arm 451 and a second supporting spring 462 connected to the second moving terminal contact arm 452; as shown in fig. 6, the lower rubber core 50 includes: and two accommodating bosses 57 which are arranged in the recessed cavity 51 and respectively enclose two supporting and accommodating spaces 56 with two side walls of the lower rubber core main body 52.
As an example, the supporting and accommodating space 56 is disposed right above the locking groove 58, so that when the locking piece 132 is fastened to the locking groove 58, the housing 10 provides an upward supporting force to the lower rubber core 50, thereby further increasing the interaction force between the movable terminal supporting portion 46 and the lower rubber core 50, and further increasing the elastic pressing force between the movable terminal 40 and the fixed terminal 30.
The assembly process and the operation principle of the coaxial switch according to the present example will be described with reference to fig. 7 to 12.
First, the gluing core 20 is mounted on the housing 10 by aligning and inserting the opposite insertion opening 22 with the insertion opening 12 (as shown in fig. 7); thereafter, the stationary terminal 30 is mounted to the stationary terminal positioning portion 23 by fixing the stationary terminal fixing portion 31 to the positioning boss 231 (as shown in fig. 8); thereafter, the movable terminal 40 is mounted to the movable terminal positioning portion 24 by fixing the movable terminal holding portion 43 in the holding space 242 and bringing the movable terminal contacting portion 45 into contact with the stationary terminal contacting portion 33 (as shown in fig. 8); then, by placing the lower plastic core 50 on the fixed terminal 30 and the movable terminal 40, and aligning the fixed terminal fixing part 41 with the fixed terminal fixing boss 55, the movable terminal supporting part 46 is located in the supporting and accommodating space 56 and contacts with the lower plastic core main body 52 at the bottom of the recessed cavity 51 (as shown in fig. 9 and 10); finally, the snap-lock portion 13 is pressed into the snap-lock groove 58 by caulking, and the coaxial switch 1 of the present example is assembled (see fig. 11 and 12).

When the electric connection between the component 1 and the component 2 needs to be cut off, a probe is inserted through the opposite insertion opening 22 and is abutted to the switch adjusting part 44, and the movable terminal contact part 45 is forced to move downwards to be separated from the fixed terminal contact part 33 by increasing the downward acting force of the probe, so that the electric connection between the component 1 and the component 2 is cut off; after the probe is removed, the moving terminal contact 45 springs back to the original position and makes a renewed contact with the stationary terminal contact 33, restoring the electrical connection of the parts 1 and 2.
To sum up, the coaxial switch of the present invention utilizes the integral design of the housing, the upper rubber core, the static terminal, the movable terminal and the lower rubber core, and the interaction between the movable terminal supporting portion bent downward at the end of the movable terminal and the lower rubber core is generated due to the contact to increase the elastic pressing force between the movable terminal and the static terminal, thereby avoiding the poor switch conduction caused by the insufficient elastic pressing force between the movable terminal and the static terminal after the durability or mechanical vibration; furthermore, the utility model discloses still through will supporting the accommodation space and locate the card locked groove directly over to when utilizing the card latch fitting to carry out the card lock fixed time to lower gluey core, the casing will be glued the core and upwards supports down, moves the terminal supporting part and glue the interaction force between the core and come further increase and move the elasticity suppression power between terminal and the quiet terminal down through the increase.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
