Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a coaxial connector, and more particularly to the structure of a high frequency coaxial connector used in mobile communication equipment.

[Conventional technology]

Conventionally, as shown in FIG. 3, this type of coaxial connector has both center conductors 21, 24 and outer conductors 22, 25 of the coaxial connector 1
One of the connectors is internally coupled to the inside of the other connector so that electrical contact is obtained by spring pressure in a direction perpendicular to the central axis. This spring pressure is generated by providing several slits in the axial direction on the circumferential surfaces of the outer conductors 22 and 25.

[Problems to be solved by the device]

In the conventional coaxial connector described above, both the center conductor and the outer conductor have one connector internally included in the other connector, and an electrical connection is obtained by spring pressure in a direction perpendicular to the central axis. Therefore, at the time of connecting the connectors, they are connected while pushing one side apart. Therefore, when the connection is performed with an excessive impact force, there is a drawback that the tips of the connectors hit each other and the spring portion is damaged.

[Means for Solving the Problems]

The coaxial connector of the present invention includes a first connector portion having a first
A central conductor fixed to the connector body, a movable shell movably provided on the outer periphery of the central conductor, a first spring for pressing the movable shell, and a movably provided on the outer periphery of the movable shell. A second connector body that has a movable member and a second spring that presses the movable member, and that is in contact with the central conductor and is in the second connector body. And a third spring that presses the contact terminal, and a fixed shell that is in contact with the movable shell and is located on the outer periphery of the contact terminal.

〔Example〕

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

FIGS. 1 (a) and 1 (b) are cross-sectional views of an embodiment of the present invention in an unattached state, and FIG. 2 is a cross-sectional view of this embodiment in an attached state.

In this embodiment, the side of FIG.
The first connector portion mounted on the left side main body) and the second connector portion mounted on the main body side of the adapter (hereinafter referred to as the right side main body) are shown in FIG. By inserting the first connector portion on the radio device side into the second connector portion on the adapter side, a lock mechanism (not shown) provided on the adapter side is formed so that both connector portions are coupled and fixed. It is assumed that

Here, in this embodiment, the central conductor 8 fixed to the shell 6 and the insulating seat (A) 7 at the center of the left body 16 and having the tip protruding, the movable shell 4, the spring coil (A) 5, and the like. The outer conductor contact portion movably attached to the left side main body 16 and the left side body provided around the outer conductor contact portion.
A movable member 3 provided with a spring coil (B) 9 and a flange 3a which allow the 16 to move freely with respect to the holding plate (A) 1.
A first connector portion having: a contact terminal 11 that is movably provided inside the right side main body 17 and is in contact with the central conductor 8 and that is connectable to the first connector portion;
And a second connector portion provided inside and having a fixed shell 10 that comes into contact with the outer conductor contact portion. On the right body 17 side, the holding plate (B) 2, the spring coil (C) 12, the insulating seat (B) 13, the insulating seat (C) 14,
Female terminals 15 and the like are provided. The movable member 3 of the first connector section is preferably made of a conductor.

According to the present embodiment having such a configuration, as shown in FIG. 2, when the first and second connector parts are coupled, the central conductor is urged by the biasing forces of the three types of spring coils 5, 9, 12. Contact between 8 and contact terminal 11 is obtained.

Therefore, when the connector is coupled by the spring coil (B) 9, the positional relationship between the movable member 3 having the flange 3a and the fixed shell 10 is maintained regardless of the variation in the distance between the holding plate (A) 1 and the holding plate (B) 2. Since it is determined, the electrical contact between the movable shell 4, the fixed shell 10, the center conductor 8 and the contact terminal 11 is stabilized.

Further, the spring coil (A) 5, the spring coil (B) 9, and the spring coil (C) 12 prevent the connector from being damaged by the impact at the time of coupling. Furthermore, since the connectors themselves approach each other by the spring coil (A) 9, the protruding length of the movable shell 4 may be increased. As a result, the contact length between the movable member 3 and the movable shell 4 is increased, and the instability is eliminated. Further, it is possible to shorten the axial dimension of the connector as a whole.

[Effect of device]

As described above, according to the present invention, the central conductor and the outer conductor are connected to each other by the pressing force in the axial direction, and the movable member and the spring are provided on the outer periphery of one of the connectors to be movably mounted on the holding plate to connect them. At this time, since the holding plates of both connectors do not come into contact with each other, damage to the connectors due to impact at the time of coupling is prevented, and since the contact position between the connectors is determined by the connectors themselves, electrical contact is stabilized and the connector length can be reduced. The effect is obtained.
