Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable communication device in which a first casing and a second casing are combined and which is suitable for being used outdoors or the like, and more particularly to a circuit of a connecting portion thereof. The present invention relates to a new waterproof structure of a connection part.

Various small portable communication devices, such as portable wireless communication devices and portable telephones, are used outdoors, but those used while moving are in the surrounding environment such as in the rain. It is required that it can be used even in a place where water drops may splash. Therefore,
It is necessary to have a structure that prevents any water droplets from entering the inside of the device.

In a portable radio communication device as shown in FIG. 8, a circuit device for transmission and reception is incorporated in a main body 1 which is a first casing, and a talking portion of a speaker or a microphone is provided inside a grill 2. It is provided. A battery 3, which is a second housing, is detachably attached to the lower portion, and an antenna 4 and an operating knob 5 are provided on the upper portion. A switch push button 6 is provided on the side surface so that an internal push button type switch element for switching between transmitting and receiving can be operated.

The unlocking member 8 can be operated and removed. Then, in the coupled state, power is supplied to the main body 1 via the contact terminals provided in the coupling surface.

From the above, all of the above-mentioned constituent parts are constructed to have a waterproof function, but in particular, the contact terminals of the coupling parts of the upper and lower casings are also detachable so that they are waterproof in the coupled state. It is necessary to be.

[0006]

2. Description of the Related Art As described above, the conventional portable wireless communication device is shown in the front view of a partial cross section of FIG. That is, by inserting the slide guides (not shown) side by side in the directions indicated by the arrows A or B, the two are coupled in the illustrated state.

In the coupled state, the two spring terminals 11 projecting downward from the body 1 side and the two fixed terminals 12 projecting upward from the battery 3 side come into contact with each other to connect the power supply circuit. ..

A rubber frame-shaped packing 13 is attached around the lower surface of the main body 1 casing so as to surround these contact-type terminals, so that the rubber frame-shaped packing 13 contacts the upper surface of the power source 3 casing to perform a waterproof function. Is configured.

Further, FIG. 10 shows another conventional structure. This is one in which a waterproof structure is formed directly around the contact-type terminals, instead of interposing a frame-shaped packing between the casings.

In this conventional structure, the fixed terminal 12 on the battery 3 side is provided.
On the other hand, the movable terminal 15 on the main body 1 side is urged downward by the coil spring 16 so as to be pressed and connected to the fixed terminal 12 in a coupled state. .. This movable terminal 15
A ring-shaped rubber packing 17 is attached to the main body 1 casing so as to surround the. As a result, the tip of the rubber packing 17 is brought into pressure contact with the surface of the housing of the power supply 3 to achieve waterproofing.

[0011]

As described above, the conventional portable communication device shown in FIG. 9 has the frame-shaped packing 1 as shown in FIG.
There was a problem that the continuous frictional force at the time of slide insertion of No. 3 was large and it was difficult to insert it against this.

In addition, in the case of FIG. 10, the ring-shaped rubber packing 17 is extremely small due to the demand for downsizing of the communication device, so that there is a problem that the assembling workability is not good.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a portable communication device which solves the above-mentioned conventional problems, has good operability, and is similarly easy to assemble.

[0014]

The portable communication device of the present invention for solving the above-mentioned problems is summarized as follows: a first casing and a second casing are slidable by respective slide guides. In a portable communication device, which is formed to be detachably coupled and in which a circuit is connected at the coupling portion via a contact terminal, a frame body surrounding the contact terminal is provided on both housing surfaces. While being provided, the frame is formed so as to abut on the inclined surface in the insertion direction.

Further, one of the abutting surfaces of the frame body may be formed as a concave line and the other may be formed as a convex line so that the concave line and the convex line are fitted in a coupled state. is there. Further, either one of the frame bodies may be formed of an elastic body.

[0016]

According to the above-mentioned gist of the present invention, since the inclined surface of the frame body surrounding the contact terminal is contacted only in the final stage of the coupling process, the insertion operation up to that point can be easily performed without any resistance. The same is true for removal.

Since the frame body is provided so as to surround the contact portion, it has a relatively large size, and a great deal of trouble and difficulty in assembling is eliminated. The configuration in which the contact surface is fitted with the combination of the concave line and the convex line can improve the reliability of the waterproof function because the contact surface can be made wider if the width is the same.

By using one of the frame bodies as an elastic body, since it is easily deformed, a gap or the like does not occur in the pressure contact state, and the contact and separation can be facilitated.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The portable communication device of the present invention will be described in detail below with reference to the drawings based on a concrete embodiment based on the outline of the configuration.

FIG. 1 is an embodiment of the present invention, and is a front view of a partial cross section of a portable radio communication device, in which a first casing 1 and a second casing 1 are provided.
Is shown separated from the housing. Further, FIG. 2 shows a side view of a partial cross section of FIG. In the figure, a circuit device for transmission and reception is incorporated inside a main body 21 which is a first housing, and a communication part such as a speaker and a microphone is provided inside the grill 22. A battery 23, which is a second housing, is detachably attached to the lower portion, and an antenna 24 and an operating knob 25 are provided on the upper portion of the main body 21. A switch push button 26 is provided on the side surface so that an internal push button type switch element for switching between transmitting and receiving can be operated.

The battery 23 is a rechargeable battery unit, and has an L shape and an inverted L shape, which are opposite to the main body 21 in opposite directions.
The slide guides 27 and 28 (FIG. 2) of a combination of shapes are easily coupled to each other, and the lock mechanism locks them so that they cannot be accidentally removed. It can be removed by sliding it in the opposite direction. Then, in the coupled state, power is supplied to the main body 21 via the contact terminals 30 and 31 provided in the coupling surface.

The above construction is almost the same as the conventional one. According to the present invention, the frame bodies 32 and 33 that surround the contact terminal portion and have the inclined surfaces in the insertion direction are formed on both the lower surface of the main body 21 housing and the upper surface of the power supply 23 housing. is there.

As shown in FIG. 3 (a), the frame bodies 32 and 33 have a low height in the front and a high height in the rear with respect to the respective housing surfaces. It is formed on an inclined surface, and the inclined surfaces contact each other at the connecting position.

In this way, a waterproof function can be obtained by bringing the inclined surfaces into close contact with each other, but the contact is made at the same time as the final coupling in the sliding process of the slide guide, and the coupling is released at the time of removal. And after all, departure is performed at the same time.

Since the inclined surfaces are in contact with each other for a moment, there is no resistance during the insertion / removal process, and the operation is smooth and easy. Figure 3
(B) of FIG. 7 shows that an annular elastic packing 35 having a U-shaped cross section is attached to the lower inclined surface side. For this, a sponge having a rubber property or a surface coating can be effectively applied. With the elastic packing 35, the waterproof function is further improved by pressing the elastic packing 35, and the elastic packing 35 is not affected by a slight gap between the inclined surfaces or inclination.

As shown in FIG. 3C, a mountain-shaped convex strip 37 is formed around the lower inclined surface, and a mountain-shaped groove-shaped recess 38 is integrally formed around the upper inclined surface. It has been formed. By doing so, the abutting width with respect to the width is increased, and the waterproof action is thereby increased. It is passed through by elastic deformation of either or both of them at the time of insertion connection, and is fitted. For this purpose, it is preferable to use an elastic material as the material of the housing. It is more preferable that one of the portions only of the frame body is made of a rubber material so as to be brought into a pressure contact state.

Next, a more specific detailed embodiment of the present invention shown in FIG. 4 will be described below. FIG. 4 shows the lower half of the main body portion in a separated state, and shows the battery portion as seen from below, but please also refer to the perspective view seen from above in FIG. In FIG. 5, one slide guide 54 is shown by an imaginary line to facilitate understanding.

In each of the drawings, a main body 51, which is a first case, has a slide guide 52 on the lower surface of the main body 51, the inward facing L-shape faces each other, and a battery 53, which is a second case. A pair of outwardly inverted L-shaped slide guides 54 are provided on the upper surface.

Battery 53 Slide guide 54 on top of housing
The fixed terminals 55 and 56 are provided at two positions in the space between them, and a frame 57 having an inclined surface in the insertion direction is provided so as to surround one fixed terminal 55. The frame 57 is formed of synthetic resin integrally with the housing. An engaging hole 59 for locking is provided in the front end direction of the frame 57.

Slide guide 52 on the bottom surface of the main body 51 housing
Between the two terminals in the series direction between the movable terminals 61, 62 of the leaf spring
Are attached with screws 65 via the rubber plate 64. A frame 66 having an inclined surface in the insertion direction is provided on the rubber plate 64 so as to surround one movable terminal 61. The frame 66 is formed integrally with the rubber plate 64.

The rubber plate 64 has movable terminals 61,
Triangular mountain-shaped protrusions 67 and 68 for receiving and supporting the tip bent portion of 62 are also integrally provided. Further, a locking leaf spring arm 71 made of synthetic resin is mounted on the rubber plate 64 with screws 72. At the tip of the locking leaf spring arm 71, an integrated lock releasing member 75 is seen through the cutout portion 74 of the housing of the main body 51 on the side surface of the housing. A downward engaging projection 76 is provided on the way.

The movable terminals 61 and 62 and the locking leaf spring arm 71 are attached to the lower surface of the housing of the main body 51 via a rubber plate 64, and both slide guides 5 in the direction of arrow A or B.
The main body 51 and the battery 53 can be coupled by engaging the two and 54 and slidingly inserting the two, so that the pair of terminals 55 and 61 can be connected by the contact between the inclined surfaces of the two frame bodies 57 and 66. In addition to being waterproof-sealed, each of the other terminals 56 and 62 is circuit-connected.

The rubber plate 64 is tightened with a screw in the screw portion in other portions, so that water leakage to the inside in this portion is prevented. Since the pair of terminals 55 and 61 on one side is waterproof and isolated in this manner, the energization state between both terminals due to water is prevented, so that the initial purpose can be achieved. By making one side waterproof, it is possible to minimize the size of the frame body for the waterproof function, and the degree of freedom in terminal arrangement can be obtained. This means that in the case of the present embodiment, the two terminal arrangements are arranged not on the straight line in the insertion direction but at the eccentric position, so that the device is downsized. Simultaneously with the above-mentioned coupling, the locking projection 76 of the locking leaf spring arm 71 is guided and fitted into the engaging hole 59 of the battery 53 casing, and the main body 51 and the battery 53 are locked and naturally separated. Not done.

With respect to the above, the connecting portion of both housings will be described in more detail with reference to sectional views of the assembled state shown in FIGS. In both figures, the slide guides 52, 54, one terminal pair, and the triangular mountain-shaped projection 67 are omitted for convenience. FIG. 6 shows a state before coupling, and FIG. 7 shows a coupled state. In both figures, the same parts as those in FIGS. 4 and 5 are designated by the same reference numerals, and therefore, for these parts, refer to the above description.

Here, a ridge 81 is formed over the entire circumference on the upper surface of the frame 57 on the battery 53 side, and the main body 51
A concave strip 82 is formed on the lower surface of the side frame 66 over the entire circumference. A side wall 85 is provided on the upper right side of the casing of the battery 53 in the figure.

From the above, as is apparent from FIG. 7, both frames 57 and 66 are in a matched state in the coupled state, and the convex strip 81 is fitted into the concave strip 82 and press-contacted based on its elasticity. It is in a state. Therefore, the waterproof isolation of the terminal portion is sure.

During the sliding process, the locking protrusion 76 of the locking leaf spring arm 71 contacts the corner of the battery 53 case with the end inclined surface at the lower right corner in the figure, and is automatically guided upward to guide the upper surface of the case. It passes through and falls into the engaging hole 59, and the vertical wall surfaces are brought into contact with each other to prevent them from coming out in the opposite direction. At this time, the right end of the slide guide of the main body 51 contacts the side wall 85 of the battery 53 to specify the connecting position.

In order to release the lock state and separate the connection, the lock releasing member 75 is pushed upward against the elasticity of the spring arm and the engagement between the locking projection 76 and the engaging hole 59 is easily released. It can be separated by sliding.
