を提供することを目的としている。 However, in the conventional antenna angle adjusting device as described above, the rotating member 6 is pushed in against the spring 8 to perform a rotating operation for adjusting the angle, and the cylindrical groove 6a and , the axial length of the friction surface formed by the circumferential surface of the cylindrical groove 7a becomes longer and its area increases, and in this state it is necessary to perform the rotation operation while applying a pushing force, so the angle adjustment operation is difficult. The problem was that it was difficult to remove. In addition, when adjusting the antenna angle with the conventional one,
The rotating member is pushed in and rotated, and the internal contact that connects to the flexible antenna and the lead-in pin that connects to the communication device are always in contact.
Due to the axial sliding and rotation of the internal contact around the axis, the contact area between the internal contact and the lead-in pin wears out prematurely, resulting in poor conduction and insufficient reliability. Since the communication device is always in a conductive state, there was also the problem that rotation and sliding noises were generated as set noises. The present invention solves the problems of the conventional ones mentioned above, allows for easy angle adjustment, and delays wear of the contact part between the internal contact and the lead-in pin.
It is an object of the present invention to provide an antenna angle adjustment device for a communication device that hardly generates noise.

A plurality of engaging holes are arranged in a circular shape on one side of the mounting member and the rotating member, and engaging protrusions provided on the other side of the mounting member and the rotating member are engaged with these engaging holes to connect an internal contact to be connected to the antenna. An introduction pin provided on the rotating member and connected to the communication device side is provided on the mounting member, and the internal contact is inserted and held in the introduction pin in a removable manner, and the engagement length of the engagement protrusion into the engagement hole is determined by adjusting the engagement length of the engagement protrusion into the engagement hole. It is longer than the insertion length into the lead-in pin.

で、通信機に雑音が発生し難い。 Since the antenna angle adjustment device for a communication device of the present invention is constructed as described above, when the rotating member is pulled out, the engaging protrusion is disengaged from the engaging hole and the rotating member can be rotated. The angle of the antenna can be adjusted by rotating the moving member, the friction area between the rotating member and the mounting member is small, and the angle adjustment operation can be easily performed with a small amount of force. Since the contact comes out of the lead-in pin, these contact parts do not simultaneously slide in the axial direction and rotate around the axis, which slows down the wear of the contact part between the internal contact and the lead-in pin, and also slows down the rotation of the rotating member. Since continuity is interrupted during dynamic operation, noise is less likely to occur in the communication device.

As shown in FIGS. 1 and 2, the antenna angle adjustment device of this embodiment includes a rotating member 11 made of a die-cast metal product to which the base end of a flexible antenna 3 is attached so as to be rotatable around an axis. and a mounting member 12 made of the same material and fixed to the portable communication device.
It has An operation knob 13 is provided on the outer end surface of the rotating member 11.
are fitted and fixed with adhesive. Further, on the inner end surface of the rotating member 11, a plurality of circular engagement protrusions 11a are provided at predetermined intervals, and the engagement protrusions 11a
As shown in FIG. 3, these are engaged with engagement holes 12a that are circularly formed at predetermined intervals in a portion of the mounting member 12 located outside the communication device. A taper is formed on at least one of the outer peripheral surface of the engaging protrusion 11a and the peripheral surface of the engaging hole 12a. A shaft 14 is fitted with a screw into the center of a circle formed by the engaging protrusion 11a of the rotating member 11 and protrudes inwardly. The internal contact 17 is penetrated,
It is loosely inserted into the center of the mounting member 12. In addition, a connector pin 24 of the flexible antenna 3 is provided in the cylindrical portion 11b perpendicular to the axis 14 of the rotating member 11.
A clamping spring 18 that is elastically supported is built in, and this clamping spring 18 is held by a synthetic resin tube 19 that is fitted and fixed to the cylindrical portion 11b. The outer end of the internal contact 17 is held between the lower end of the clamping spring 18, and the inner end of the internal contact 17 is connected to the shaft 1.
It protrudes inward from 4. In the mounting member 12, a cylindrical body 12c extends inside the communication device from a mounting plate 12b in which a mating hole 12a is formed and a screw hole 12e is provided, and an introduction pin 20 is built in the inner end of the cylindrical body 12c. The introduction pin 20 is held in a synthetic resin cylinder 21 that is fitted and fixed to the inner end of the cylindrical body 12c, and the inner end protruding from the shaft 14 of the internal contact 17 is removably inserted into the introduction pin 20. held. The inner end of the introduction pin 20 protruding from the synthetic resin tube 21 is connected to the communication device, and the inner end crimped portion 12d of the cylindrical body 12c is grounded. Further, a coil spring 22 is interposed between the step 14a of the shaft 14 and the mounting plate 12b of the mounting member 12,
The rotating member 11 is urged toward the pushing side, that is, inwardly, via the shaft 14 by the coil spring 22 . The engagement length L ₁ of the engagement protrusion 11a is
Insertion length of internal contact 17 into introduction pin 20
L is longer than ₂ . In FIG. 1, reference numeral 23 indicates an E-ring attached to the internal contact 17;
17a is the large diameter part of the internal contact 17, and E
Internal contact 1 is formed between ring 20 and large diameter portion 17a.
7 is longitudinally positioned. Furthermore, the synthetic resin cylinders 16, 19, and 21 are preferably made of fluororesin. Next, the antenna angle adjustment operation by the antenna angle adjustment device of this embodiment will be explained. Similar to the conventional device shown in FIG. 4, with the mounting member 12 fixed to the communication device with screws passed through the screw holes 12e,
When the operating knob 13 is held and the rotating member 11 is pulled out against the spring force of the coil spring 22, the engaging protrusion 11a
The meshing of the meshing hole 12a is disengaged, and the rotation member 11 is unlocked. When the rotating member 11 is pulled out to some extent, the engaging protrusion 11a rotates while sliding on the mounting plate 12b surface of the mounting member 12, and the flexible antenna 3 also rotates together with the rotating member 11. When the rotating member 11 is further pulled out, the rotating member 1
1 rotates in a non-contact state since the engaging protrusion 11a separates from the mounting plate 12b. Therefore, the rotating member 11
Even in a contact state where the engaging projection 11a slides on the surface of the mounting plate 12b, the friction area is small, so it can be easily rotated with a small force, and the engaging projection 11
In the non-contact state of a, rotation can be made with even smaller force. Furthermore, when the rotating member 11 is pulled out, the internal contacts 17 are also pulled out, and the internal contacts 1
7 is pulled out from the introduction pin 20, and the above-described contact and non-contact rotation of the rotating member 11 can be performed in a non-conducting state with respect to the communication device side. Therefore, when the rotating member 11 rotates, noise due to rotational sound is less likely to be generated in the communication device. Furthermore, since there is no contact portion between the flexible antenna 3 and the introduction pin 20 where sliding and rotation occur at the same time, poor conduction due to early wear of the contact portion is unlikely to occur. Furthermore, in this embodiment, the connector pin 24, the internal contact 17, and the introduction pin 20 are connected to the rotating member 1.
1. Since it is housed in the mounting member 12, rainwater, dust, etc. do not enter the conduction path, and the coaxial line can be easily routed. In the present invention, the engaging protrusion 11a and the engaging hole 12
The number a is not necessarily limited to the number in the embodiment, but if the number of engagement holes 12a is increased and the angular interval between them is reduced, the number of engagement protrusions 11a and engagement holes 12 can be reduced.
It is possible to increase the number of locking points where a and a engage with each other. Furthermore, in the present invention, the rotating member 11 may be provided with an engaging hole and the mounting member 12 may be provided with an engaging protrusion.

る。 As explained above, according to the present invention, the engagement hole provided on one side of the mounting member and the rotating member is engaged with the engagement protrusion provided on the other, so that when the rotation member is pulled out, the engagement protrusion is removed from the meshing hole and the rotating member is rotated to adjust the angle of the flexible antenna, and the angle adjustment operation with good feeling can be easily performed with a small amount of force. In addition, according to the present invention, when the mating protrusion comes off the mating hole, the internal contact slips out from the lead-in pin, so these contact parts wear slowly, are less likely to cause poor conduction, and are highly reliable even after long-term use. Furthermore, when the rotating member rotates, conduction is interrupted, so
The effect is that noise is less likely to occur in the communication device.
