Abstract

PURPOSE:To simply and correctly fit or remove a radio main body by hooking the outer end section of the radio main body with a stopper when the radio main body is inserted into a chassis, and releasing the hook of the stopper and the coupling of connectors with an extracting member when the radio main body is extracted from the chassis. CONSTITUTION:When a radio main body 90 is to be stored in a portable chassis, the radio main body 90 is thrust into the portable chassis while grooves of the radio main body 90 are coupled with rails of side covers. Connectors 66, 92; 70, 94 are coupled with each other. When the radio main body 90 is to be extracted from the portable chassis, a lever 40 is rotated while its inside 40a is pressed. A circular arc-shaped plate spring 38 pushed by the radio main body 90 is deflected, an extracting metal 36 is protruded to the outside and rides over a stopper 46, thus the hook state is released. The coupling between the connectors 66, 92; 70, 94 respectively is released, and the radio main body 90 is extracted to the outside of the portable chassis together with the extracting metal 36.

A stopper is provided on the casing to press the other end of the radio main body to prevent the radio main body from coming out of the casing, and the stopper release means and connector removal means are provided in the radio main body drawer member (36). ) and configure it.

INDUSTRIAL APPLICATION FIELD The present invention relates to a portable housing structure for a vehicle-mounted wireless device such as a car phone.

In recent years, with the diversification of communications circumstances, the uses of car phones have been rapidly expanding. This type of in-vehicle wireless device is constructed by installing a wireless device with a unique code inside the trunk of the vehicle, and installing a general-purpose handset with a dialing function (1 handset), a speaker, and an antenna inside and outside the driver's seat. The configuration is as follows. Recently, small radio equipment bodies have become available, and
There are many requests to make calls at a location away from the car, and for this reason, the main body of the radio, which is installed in the trunk, is configured to be detachable using connectors, and general-purpose parts such as the handset, speaker, and antenna can be carried. An in-vehicle radio device is now in the practical stage of being put into practical use, in which a set of radio devices is assembled into a portable housing so that the radio device itself can be shared both inside and outside the vehicle. Portable casings used in such applications are required to be able to easily attach and detach the radio, as it is expected that attaching and detaching the radio will be complicated. . Also, since the radio itself is relatively heavy,
When housed in a portable housing, it is required that the connector connection will not be easily disconnected due to impact or the like.

BACKGROUND OF THE INVENTION FIG. 9 is an overall perspective view showing an example of a portable casing for an automobile. In the figure, 1 is a portable housing case;
Inside, there is a built-in housing chassis to which various parts such as a speaker and a power supply device are attached, and which is configured to accommodate the main body of the radio. 2 is an antenna protruding to the outside of case 1; 3 is a handset connected to the inside of case 1 via cord 4; 5 is a shoulder band attached to case 1; 6 is a handset seat fixed to the top of case 1. It is.

The conventional portable housing structure for accommodating the main body of the radio is the first.
This will be explained with reference to FIG. In explaining this conventional example,
Terms such as "upper" and "lower" indicating directions refer to the case observed in FIG. In this portable housing structure, a radio main body 7 having a connector 8 on the top and a groove 9 formed halfway down on both sides from the top is integrally provided inside a housing chassis 10, for example. It is inserted into the case chassis 10 by aligning the groove 9 with the rail 11 that has been formed, and the connector 8 of the radio main body 7 is removably fitted to the connector 14 on the side of the case shear 10. .

When the radio main body 7 is housed in the housing chassis 10, the lid member 12 to which the elastic body 13 such as a sponge is attached is attached to the lower side of the housing chassis 10, as shown in FIG. 10(A). connectors 8 and 14 regardless of impact etc.
It ensures that the connection between them is maintained. When removing the radio main body 7 from the housing chassis 10, refer to the same figure (B).
As shown in FIG.
By pulling the straps 16 housed on both sides of the inside in the directions of arrows A and B, force is applied to the radio main body 7 via the L-shaped fitting 15 that locks on the upper end of the radio main body 7, and this It is designed to be removed in the direction of arrow C.

In some cases, the elastic body 13 is elastically deformed more than necessary, resulting in incomplete connection between the connectors 8 and 14. Furthermore, because conventional portable casings were designed for small-volume production, they were made of sheet metal, resulting in poor yields and frequent failures.

The present invention has been made in view of these points, and its purpose is to have a simple structure, to allow the main body of the radio to be easily taken out, and to be able to easily remove the main body of the radio set housed in the housing. It is an object of the present invention to provide a portable housing structure for a vehicle-mounted radio device in which a connector connection is not easily disconnected.

Problems to be Solved by the Invention In general, the connectors used in the main body of the radio are multi-pin type, so their mating force is relatively strong. Therefore, with the above conventional structure, the force is applied equally to the straps 16 on both sides. It is difficult to add the radio main body 7 to the housing chassis 10.
could not be easily removed from the In addition, since the weight of the radio main body 7 is relatively large, the above-mentioned technical problem is solved by providing a connector at one end and a connector at both sides. The main body of the radio has a groove formed halfway from one end to the other end, and is provided inside the portable casing. A portable casing for a vehicle-mounted radio device, which is inserted into the portable casing with the groove aligned with the J rule, and the connector of the radio device main body is removably fitted to the connector on the portable casing side. In the body structure, a second rail is provided on the battery cover attached to the inside of the casing, a radio device main body drawer member is attached to the battery cover so as to be movable while being guided by the second rail, and the first rail When the radio main body is inserted into the casing along This problem can be solved by providing a means for extracting the connector which also functions as a means for pulling out the connector on the radio device main body pull-out member.

Preferably, the stopper release means and connector removal means includes a plate spring integrally provided on the back side of the radio device main body drawer member, and a pair of plate springs rotatably attached to the front side of the radio device main body drawer member. It consists of a lever.

Operation To accommodate the radio main body in the housing, fit the groove of the radio main body into the first rail provided inside the portable case and push the radio main body into the housing. Can be stored in the body. In this state, the stopper presses the other end of the radio device main body, thereby preventing the radio device main body from slipping out of the casing.

On the other hand, when removing the radio unit from the portable case,
Preferably, a stopper release means and connector removal means, which is controlled by a leaf spring and a pair of levers, is activated to first release the stopper and then remove the connector on the main body of the radio from the connector on the portable housing. Make sure to pull out the main body of the machine towards you.
