Problems solved by technology

[0006] Therefore, even if it can be attached and detached along the axial direction of the plug 18, or a flexible material is used for the antenna part 12, if a certain force or more is applied to the antenna part 12 in a direction different from the axial direction, the antenna may be damaged.

Embodiment 1

[0030] based on Figure 1~3 Embodiment 1 of the attachment and detachment mechanism of the small antenna of the present invention will be described.

[0031] exist image 3 Among them, a display 52 is attached to an electronic device main body 20 such as a notebook computer through a hinge portion 21 so as to be openable and closable. An antenna mounting portion 22 is provided at a side end portion of the hinge portion 21 to fit and mount an antenna holder 23 to be described later.

[0032] The antenna holder 23 is made of an insulator such as plastic, and includes a fitting tube 25 having a diameter of approximately 11 mm and openings at both ends, and a base 26 extending from the fitting tube 25 to one side. In one opening of the fitting cylinder 25, a locking protrusion 28 is formed on an inner peripheral portion near the opening end so as to detachably fit a later-described L-shaped connector 24 for rotation. The opening end side of the locking protrusion 28 serves as a t...

Embodiment 2

[0045] In the above-mentioned first embodiment, the O-ring 41 is provided on the rotation L-shaped connector 24 on the antenna part 12 side, and the locking protrusion 28 is provided on the fitting cylinder part 25 on the antenna holder 23 side, and vice versa. ,Such as Figure 4 As shown, the locking protrusion 28 may be provided on the rotation L-shaped connector 24 on the antenna unit 12 side, and the O-ring 41 may be provided on the fitting cylinder 25 on the antenna holder 23 side. In this case, use the force of the contact spring 31 to press the engaging convex portion 28 on the side of the fitting cylinder portion 38 into the side surface of the O-ring 41, and restrict the movement of the antenna portion 12 due to its own weight or a relatively small force. to become a stable bonded state.

Embodiment 3

[0047] In the above-mentioned embodiments 1 and 2, the O-ring is made into a ring shape, such as Figure 5 As shown, a plurality of balls 54 may also be arranged in the insertion groove 40 and be biased outward by a spring 55 . In this case, the wall portions on both sides of the fitting groove 40 are slightly curved inwardly above the center of the ball 54 so that the ball 54 does not escape from the fitting 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] In the past, it is known that, for example, in Figure 6 In the shown notebook computer 10, a modem card 11 is detachably inserted and used, and an antenna unit 12 for wireless communication is mounted on the modem card 11, which is erected when in use and folded when not in use (patent Document 1-JP-A-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 th...
