Example Embodiment

[0029] Example 1

[0030] The first embodiment of the attachment and detachment mechanism of the small antenna of the present invention will be described based on FIGS. 1 to 3.

[0031]In FIG. 3, a display 52 is attached to a main body 20 of an electronic device such as a notebook computer so that it can be opened and closed by a hinge 21. An antenna mounting portion 22 for inserting and mounting an antenna holder 23 described later is provided at the side end of the hinge portion 21.

[0032] The antenna holder 23 is composed of an insulator such as plastic, and is composed of a fitting cylindrical portion 25 with a diameter of approximately 11 mm that is open at both ends, and a base 26 extending from the fitting cylindrical portion 25 to one side. In one opening of the fitting cylindrical portion 25, a locking protrusion 28 is formed in the inner peripheral portion near the opening end so that the later-described rotating L-shaped connector 24 can be detachably fitted. The open...

Example Embodiment

[0044] Example 2

[0045] In the above-mentioned first embodiment, the O-ring 41 is provided on the rotating L-shaped connector 24 on the antenna portion 12 side, and the locking protrusion 28 is provided on the fitting cylinder portion 25 on the antenna bracket 23 side. As shown in FIG. 4, a locking protrusion 28 may be provided on the rotating L-shaped connector 24 on the antenna portion 12 side, and an O-ring seal 41 may be provided on the fitting cylindrical portion 25 on the antenna bracket 23 side. In this case, the locking protrusion 28 on the side of the fitting cylinder 38 is pressed into close contact with the side of the O-ring 41 by the force of the contact spring 31 to restrict the movement of the antenna portion 12 due to its own weight or small force. Thereby it becomes a stable bonding state.

Example Embodiment

[0046] Example 3

[0047] In the above-mentioned embodiments 1 and 2, the O-ring is formed into a ring shape. As shown in FIG. 5, a plurality of balls 54 may be arranged in the insertion groove 40 and a spring 55 may be used to force outward. In this case, the wall portions on both sides of the insertion groove 40 are configured to be slightly curved inwardly above the center of the ball 54 so that the ball 54 does not escape from the insertion groove 40.

Abstract

To provide an attaching/detaching mechanism of compact antennas which would not damage an antenna or a device even if a force more than a certain strength is applied from any direction of the antenna part. An antenna housing 23 formed in an electronics main body 20 is connected to a rotatory L-shaped connector 24 of an antenna part 12. A fitting groove 40 is formed on the periphery of a male fitting cylinder 38 on the rotatory L-shaped connector 24 side to fit an O-ring 41 and an engaging projection 28 which presses to engage the O-ring 41 is formed on the inner wall of a female fitting cylinder 25 on the antenna housing 23 side so that they can be rotatably and attachably/detachably connected. A contact member 43 whose tip is exposed is attached to the fitted cylinder 38 and a contact spring 31 is prepared oppositely to the contact member 43 so that it can press the O-ring 41 to the engaging projection 28.

Description

technical field [0001] The invention relates to a mounting and dismounting mechanism for small antennas installed on electronic equipment such as personal computers and telephones to prevent damage to the equipment when abnormal force is applied. Background technique [0002] Conventionally, it is known that, for example, in a notebook computer 10 as shown in FIG. , make it fold when not in use (Patent Document 1-Japanese Unexamined Publication No. 2003-32016). [0003] More specifically, the above-mentioned antenna unit 12 is crank-connected with the first L-shaped connector 13 for rotation and the L-shaped connector 14 for the second rotation, and the plug 18 of the L-shaped connector 14 for the second rotation is inserted and connected to the modem. on the socket 19 of the card 11. The above-mentioned first rotation L-shaped connector 13 and the second rotation L-shaped connector 14 are rotatably engaged with the first rotation L-shaped connector 13 on the matching groo...
