[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting portion of a modular type probe in which a cable connecting portion and a stylus mounting portion are separately constructed and used in an appropriate combination according to the application.

[0002]

2. Description of the Related Art A holding force in a fitted state of a cable connecting portion and a stylus mounting portion depends on a tightening force of a receiving spring which receives a contact. In addition, a method of screw-connecting the shell portion and a method of providing a lock mechanism are also used.

[0003]

When the holding force is increased, the tightening force of the receiving spring tends to make the receiving spring physically large because it is necessary to increase the acting force of the receiving spring. Further, the screw connection has a drawback that the workability is poor because the screw mechanism needs to be screwed a few times for each rotation when changing the combination, and the structure of the lock mechanism is complicated.

[0004]

The fitting portion of the modular probe according to the present invention is applied to the modular probe in which the cable connecting portion and the stylus mounting portion can be freely inserted and removed. Both of the fitting / removing ends are concentrically provided with a contact, an insulating material, an outer conductor, and a cover in this order from the center to the outer side in the radial direction. The contacts are male and female types that can be inserted into and removed from each other, and an insulating material surrounds each contact. The outer conductor is tubular and has an insulating material fitted inside.One insulating material is located inside the opening of the fitting / removing end and the other insulating material is placed between the contact and the outer conductor. An annular groove for receiving is formed. The cover is tubular and forms an annular groove with the outer conductor.

The outer diameter of one outer conductor matches the inner diameter of the other outer conductor, the outer diameter of the other outer conductor is slightly larger than the inner diameter of one cover, and the outer diameter of one cover is the other. It fits the inside diameter of the cover, and one cover is made of elastic material. In both of these cases, the outer conductor of the other presses one cover into pressure contact with the other cover in the fitted state of both.

[0006]

[Function] The opening of the cable connecting portion and the fitting / removing end portion of the stylus mounting portion are aligned on the same center line. In this state, the male and female contact elements face each other, and the other insulating material faces the annular groove between the one contact element and the outer conductor. Further, one outer conductor faces an annular groove between the other insulating material and the outer conductor, and the other outer conductor faces an annular groove between the one outer conductor and the cover. Furthermore, one cover faces the annular groove between the other outer conductor and the cover, and the other cover points to the upper space of the outer peripheral surface of the one cover.

In this state, both are relatively pushed in. Partial parts that face each other are fitted together, and the contactors and the outer conductors are closely fitted together to establish conduction. Since the other outer conductor is fitted to the one outer conductor while pushing the one cover in the radial direction on the outer peripheral surface, the outer peripheral surface of the one cover is sequentially pressed against the inner peripheral surface of the other cover. . Therefore, in the mating completed state, the contacts, the other insulating material and one outer conductor, the other outer conductors, the other outer conductor and one cover,
Since the respective crimping forces between the covers are combined, the crimping forces of the two become extremely large.

Embodiment 1 is a cable connecting portion to which a coaxial cable 2 is connected. Reference numeral 3 denotes a stylus mounting portion to which a stylus 4 is mounted at the tip. Reference numeral 5 is a fitting / removing end portion of the cable connecting portion 1, and 6 is a fitting / removing end portion of the stylus mounting portion 3. The fitting end 5 is concentric,
A male contactor 7, an insulating material 8, an outer conductor 9, and a cover 10 are provided in this order from the center outward in the radial direction. Also,
The fitting / removing end portion 6 is concentrically arranged in order from the center to the outer side in the radial direction,
It is provided with a female contactor 11, an insulating material 12, an outer conductor 13, and a cover 14.

The insulating material 8 surrounds the male contactor 7, and the insulating material 12 surrounds the female contactor 11. The outer conductors 9 and 13 are cylindrical, and the insulating materials 8 and 12 are fitted inside at predetermined positions. And the insulating material 8 is the fitting / removing end portion 5.
Of the annular groove 16 located inside the opening 15 of the other and receiving the other insulating material 12 between the contactor 7 and the outer conductor 9.
Is formed. The covers 10 and 14 are tubular and have annular grooves 17 and 18 formed between them and the outer conductors 9 and 13, respectively.

The outer diameter of the outer conductor 9 matches the inner diameter of the outer conductor 13. The outer diameter of the outer conductor 13 is slightly larger than the inner diameter of the one cover 10, and the outer diameter of the cover 10 matches the inner diameter of the other cover 14. The cover 10 is made of an elastic material. Double fitting end 5
In the fitted state of Nos. 6 and 6, the other outer conductor 13 pushes the one cover 10 in the radial direction, so that the outer peripheral surface of the cover 10 is in pressure contact with the inner peripheral surface of the other cover 14.

The cable connecting portion 1 and the fitting / removing ends 5 and 6 of the stylus mounting portion 3 are opposed to each other on the same axis. When both are joined and pushed in, the male and female contactors 7 and 11 and both outer conductors 9 and 13 are closely fitted and electrically connected. The outer conductor 13 presses the cover 10 against the cover 14.

[0012]

According to the present invention, the cable connecting part and the stylus mounting part can be fitted or removed by pushing or pulling out on the coaxial line, the workability in the case of replacement can be improved, and one external part in the fitted state. Since the conductor pushes and spreads the other cover and crimps it to the one cover, the pull-out resistance can be greatly improved.
