Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coaxial cable holding mechanism that uses a coaxial cable hood to hold a coaxial cable connected to a coaxial connector.

[Conventional technology]

Conventionally, a mechanism shown in FIG. 4 has been proposed as a mechanism for holding a coaxial cable used in electronic equipment when it is attached to a coaxial connector. Here, 1 is a coaxial connector,
Reference numeral 2 denotes a coaxial cable. After exposing the sheath 3 and shield 4 of the coaxial cable 2 and connecting the central conductor (not shown) to the coaxial connector 1, the coaxial cable 2 is covered with a hood 5. This hood 5 has a solder hole 6 for holding the shield, and after the hood 5 is fixed to the coaxial connector 1 with a screw 7, the shield 4 is soldered through the solder hole 6 to be fixed and held.

[Problem that the invention attempts to solve]

The conventional holding mechanism described above holds the shield 4 of the coaxial cable 2 after being soldered in the solder hole 6 for holding the shield. Mechanically, this soldering must be performed after the cable center conductor and connector center conductor are soldered and after the hood 5 is fixed to the coaxial connector 1 with the screw 7. For this reason, heat during soldering is likely to be dissipated throughout the hood 5, and the amount of heat during soldering increases, resulting in poor workability. Further, there is a problem that the insulation between the inner and outer conductors of the coaxial cable 2 may be destroyed.

An object of the present invention is to provide a coaxial cable holding mechanism that can improve workability during soldering and prevent damage to the insulation of the coaxial cable.

[Means for solving problems]

The coaxial cable holding mechanism of the present invention is a mechanism in which a coaxial cable is held and connected between a coaxial connector and a hood attached to the coaxial connector, and the connecting end of the coaxial cable has a small-diameter recess in a part. The clamp is fitted and the shield of the coaxial cable is folded back onto the hood, and the hood is formed with a small diameter constriction corresponding to the recess so that the coaxial cable is held between the recess and the hood.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is a perspective view of a coaxial cable holding mechanism to which an embodiment of the present invention is applied, and Fig. 2 is a coaxial cable 6
FIG. 3 is a partially exploded perspective view of the tip.

In FIG. 2, the tip of the coaxial cable 2 is
The insulating coating 3 is peeled off to expose the shield 4. Then, the shield 4 portion is inserted into a cylindrical clamp 8 having an inner diameter approximately equal to the outer diameter of the coaxial cable 2, and the end thereof is folded back to the tip of the clamp 8. Note that the clamp 8 is partially formed with an annular recess 9 having a reduced diameter. As shown in Figure 3, the coaxial connector 1
The center conductor 10 of the coaxial cable 2 is connected to the center conductor 11 of the coaxial connector 1. and,
A hood 5 is placed on top of this and fixed to the coaxial connector 1 with screws 7, resulting in the configuration shown in FIG. Note that a constricted portion 12 with a reduced inner diameter is formed at the base of the hood 5, and this corresponds to the recessed portion 9 of the clamp 8.

Therefore, according to this configuration, in the state configured as shown in FIG. The coaxial cable 2 is maintained in a state where sufficient electrical connection between the shield 4, the hood 5, and the coaxial connector 1 is obtained. Therefore, coaxial cable 2
There is no need to solder after attaching the coaxial cable, which improves work efficiency when connecting the coaxial cable.

[Effect of idea]

As explained above, in the present invention, a clamp having a small diameter recess is fitted to the connecting end of the coaxial cable, the shield of the coaxial cable is folded back onto this, and the hood is fitted with a clamp having a small diameter recess. Since the coaxial cable is held between the small-diameter constriction and the recess, a sufficient electrical connection can be made without soldering, eliminating instability caused by soldering and making work easier. This has the effect of shortening time.
