Description

[0001] COAXIAL CONNECTOR FOR INSPECTION [0002]

The present invention relates to a coaxial connector for inspecting, and more particularly, to a coaxial connector for inspecting which can be easily fastened to a connecting portion to which a coaxial cable is connected.

The coaxial cable consists of an inner conductor placed at the center of the cable, an insulating material surrounding it, an outer conductor, and an outer sheath of the outermost layer. The coaxial cable has a central concentric inner conductor. With this concentric circular structure, it is possible to transmit a signal while receiving less electrical interference than a general wire.

Such a coaxial cable is widely used because it can safely and reliably transmit an electric signal to various test apparatuses and precision electronic apparatuses. Therefore, a coaxial cable is used as a connection unit of a device to be inspected; For example, there is a need for a connector that is easily detachable while being stably connected to an RF switch.

These connectors have been developed in many ways and various types of connectors have been used.

The coaxial connector and the coaxial connector of the present invention are described in detail in coaxial connector and coaxial probe for measurement (Patent Literature 1), coaxial connector for inspection and receptacle (Patent Literature 10-1239309) And the like.

However, in Patent Documents 1 and 2, when the coaxial connector is connected to the receptacle, since the operator must use both hands to connect the coaxial connector to the connection portion of the object to be inspected, there is a disadvantage in that the connection of the coaxial connector is troublesome. There is a great risk of damaging the connection portion of the object to be inspected because the coaxial connector has to be operated using both hands.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

The opened upper end of the upper housing 111 is sealed by the cover 190 and the lower end of the lower housing 112 is provided with a through hole 112a through which the signal pin 120 and the ground pin 140 pass, . To this end, the lower region of the lower housing 112 has an inverted conical shape whose diameter gradually decreases toward the lower end. In particular, the diameter of the through hole 112a is preferably slightly larger than the diameter of the ground pin 140 for smooth axial movement of the ground pin 140.

Meanwhile, a partition plate 111a for axially partitioning the inner space of the upper housing 111 is formed. An upper region of the partition plate 111a is defined as a first region 111a1 and a lower region of the partition plate 111a is defined as a second region 111a2 do. The inner diameter of the first region 111a1 may be the same as the inner diameter of the second region 111a2 and the inner diameter of the first region 111a1 may be the same as the inner diameter of the second region 111a2 It is preferable that the diameter is larger than the inner diameter.

The inner space of the lower housing 112 is larger than the inner diameter of the second area 111a2, and the positioning unit 150 is disposed in the inner space.

The upper housing 111 and the lower housing 112 are preferably made of a conductive material to electrically contact the outer conductor of the coaxial cable 10 and serve as a ground. For example, in the present embodiment, the upper housing 111 and the lower housing 112 are made of brass.

The signal pin 120 is a means for electrically contacting the inner conductor 11 of the coaxial cable 10 and contacting the electrode of the RF switch 20. The signal pin 120 is inserted into the housing unit 110, 10 and the distal end portion thereof is protruded to the outside through the through hole 112a of the lower housing 112. [ For example, the signal pin 120 may be formed in a pin shape elongated in the axial direction so as to penetrate through the partition plate 111a of the upper housing 111 and the through hole 112a of the lower housing 112, . Thus, the rear end region of the signal pin 120 is disposed in the first region 111a1 of the upper housing 111, and the front end region is protruded to the outside of the lower housing 112. [

Meanwhile, the rear end of the signal pin 120 is supported by the first spring 170 so that a pressing force is always applied toward the front end of the signal pin 120 while being moved by a predetermined distance in the axial direction. At this time, the first spring 170 is arranged to always maintain the compressed state to some extent, and even if the signal pin 120 is moved in the backward direction by the elastic force of the first spring 170, do.

In order to dispose the first spring 170 in the first region 111a1 of the upper housing 111 while providing a space for moving the signal pin 120 by a predetermined distance in the axial direction, .

The rear end region of the dielectric 130 is disposed in the first region 111a1 of the upper housing 111 and the front end region is disposed in the lower housing 112. [

The outer diameter of the rear end region is the same as the inner diameter of the first region 111a1 of the upper housing 111 so that the dielectric 130 is fixed to the inside of the housing unit 110. [ The outer diameter of the front end region of the dielectric 130 is smaller than the inner diameter of the second region 111a2 of the upper housing 111 by the thickness of the ground pin 140 for axial movement of the ground pin 140 . A space corresponding to the thickness of the ground pin 140 is formed between the outer circumferential surface of the dielectric 130 and the inner circumferential surface of the second region 111a2 of the upper housing 111. [ The distance between the outer circumferential surface of the dielectric 130 and the inner circumferential surface of the second region 111a2 of the upper housing 111 is preferably less than the thickness of the ground pin 140 for smooth axial movement of the ground pin 140. [ It would be better if it is formed a little larger.

The dielectric 130 is made of an insulating material to insulate the connection conductor 160 and the signal pin 120 from the housing unit 110 and the ground pin 140. For example, in this embodiment, it is made of Teflon.

On the other hand, a pair of protrusions 141 are provided at positions facing each other on the outer peripheral surface of the rear end region of the ground pin 140.

The rear end of the ground pin 140 is supported by the second spring 180 so that a pressing force is always applied toward the front end of the ground pin 140 while the ground pin 140 moves a predetermined distance in the axial direction. At this time, the second spring 180 is arranged to always maintain the compressed state to some extent, and even if the ground pin 140 is moved to the rear end region by the elastic force of the second spring 180, .

The second spring 180 is disposed in the second region 111a2 of the upper housing 111 and the rear end thereof is supported by the partition plate 111a and the rear end region of the ground pin 140 .

The positioning unit 150 determines the stop position of the ground pin 140 after the axial movement of the ground pin 140. The position determining unit 150 determines the stop position of the ground pin 140 by interlocking with the axial movement of the ground pin 140 in the inner area of the lower housing 112 So as to rotate.

3 and 4, the positioning unit 150 includes a plurality of protrusions (not shown) extending in the circumferential direction around the area through which the ground pin 140 penetrates in the axial direction, 141 are disposed and moved. At this time, in the inner space of the positioning unit 150, a plurality of crystal grooves 151 to 155 for determining the rotation and stop positions of the positioning unit 150 are formed while the protrusions 141 are interrupted at the upper and lower ends thereof do.

At this time, the upper rotating body 150a and the lower rotating body 150b are formed in a cylindrical shape, and the ground pin 140 passes through the center of the upper rotating body 150a and the lower rotating body 150b. At this time, in order to rotate the upper rotating body 150a and the lower rotating body 150b at the same rotating speed, a coupling protrusion 156 is formed on the joint surface of the upper rotating body 150a, A coupling groove 157 into which the coupling protrusion 156 is inserted is formed on a surface of the coupling protrusion 156 so that the coupling protrusion 156 and the coupling groove 157 are engaged with each other.

An inner space through which protrusions 141 formed on the outer circumferential surface of the ground pin 140 moves is formed on the joining surfaces of the upper and lower rotors 150a and 150b. The inner space is formed in the circumferential direction around the region through which the ground pin 140 penetrates, and an axial space is formed by a distance that the ground pin 140 is moved in the axial direction, as described above.

Particularly, the plurality of crystal grooves 151 to 155 are formed at the upper and lower ends of the inner space formed by coupling the upper and lower rotors 150a and 150b. The protrusions 141 of the ground pin 140 are brought into contact with the crystal grooves 151 to 155 and the upper and lower rotors 150a and 150b are rotated by the shape and position of the crystal grooves 151 to 155, And the position of the ground pin 140 is determined in conjunction with this.

For example, the plurality of crystal grooves 151 to 155 formed in the positioning unit 150 are formed at the lower end of the inner space, that is, at the upper end of the lower rotating body 150b, A first crystal groove (151) in which a region is formed; The uppermost portion of the first recess 151 is formed at the upper end of the inner space, that is, at the lower end of the upper rotating body 150a, A second crystal groove (152) in which a maximum depth region is formed at a position spaced apart from the immediately above upper position; The lower portion of the inner space, that is, the upper end of the lower rotating body 150b, is inclined downwardly to one side of the maximum depth region of the second crystal groove 152, A third crystal groove 153 in which a maximum depth region is formed at a position spaced apart from a position directly underneath the first crystal groove 153; The uppermost portion of the third recess 153 is formed at the upper end of the inner space, that is, at the lower end of the upper rotating body 150a, A fourth crystal groove 154 in which a maximum depth region is formed at a position spaced apart from the upper right position of the fourth crystal groove 154; The lower portion of the inner space, that is, the upper end of the lower rotating body 150b, is inclined downward to one side directly under the maximum depth region of the fourth crystal groove 154, And a fifth crystallization groove 155 in which a maximum depth region is formed at a position spaced apart from the lower right position of the first crystal growth chamber.

At this time, the first crystal groove 151 and the fifth crystal groove 155 are formed at the same height, and the second crystal groove 152 and the fourth crystal groove 154 are formed at the same height, The crystal grooves 153 are formed closer to the positions of the second crystal grooves 152 and the fourth crystal grooves 154 than the positions of the first crystal grooves 151 and the fifth crystal grooves 155.

In the present embodiment, a pair of protrusions 141 are formed on the ground pin 140 so that each of the protrusions 141 is cut into the same crystal grooves 151 to 155 of the plurality of crystal grooves 151 to 155 A pair of the first crystal groove 151 to the fifth crystal groove 155 are formed at positions facing each other. In other words, the first to fifth crystal grooves 151 to 155 are sequentially formed in the inner space of the positioning unit 150 in one direction, and thus the first crystal groove group is formed First to fifth crystal grooves 151 to 155 are formed in the positioning unit 150 so as to face the first to fifth crystal grooves 151 to 155, And are sequentially formed to form a second group of crystal grooves.
