Description

[Detailed Description of the Invention] The present invention is a device in which two housings are removably connected, which has a simple configuration without using screws, and can be reliably locked at the same time as installation, and is also easy to remove. This allows the lock to be released at any time.

For example, a portable television receiver may use a battery as a power source. In this case, a battery is provided separately from the television receiver body and stored in a special case, and when in use, the battery is installed separately from the television receiver body. It may be attached to the main body. Of course, when the battery is not in use, the battery case must be removed from the receiver body, but it is desirable that the battery case can be easily attached and removed.

The present invention provides effective means in such cases, and one embodiment thereof will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is a first casing, for example, a television receiver body, and 2 is a second casing, for example a battery case, which is composed of a case body 3 and a lid 4. . Here, the first casing and the second casing are removably connected, but as shown in FIG. 2, the lid 4 of the second casing 2
A plurality of L-shaped locking claws 4a are integrally provided, and the case body 3 is integrally provided with an elastic locking piece 3a as shown in FIGS. 2 and 4. This locking piece 3a has a finger hook at its tip for use in unlocking the locking piece 3a, and its curved end protrudes outward from a notch provided in the lid body 4.

On the other hand, as shown in FIG. 3, the first housing 1 has a hole 1a in its bottom surface into which the locking claw 4a is inserted and engaged.
and a recess 1b into which the lock piece 3a fits.

In the above configuration, the first case 1 and the second case 2
When joining, first insert each locking claw 4a into the hole 1a of the first housing 1 as shown in FIG. 5a,
The first casing 1 is moved in the direction of arrow A with respect to the second casing 2. As a result, when the lock piece 3a collides with the first case 1, the lock piece 3a deforms due to elasticity as shown in FIG. The piece 3a passes over the lower end of the first case 1, and the lock piece 3a fits into the recess 1b of the first case 1, as shown in FIG. 5c. At the same time, the locking claw 4a locks the first housing 1.
The first casing 1 and the second casing 2 are coupled to each other.

Next, when separating the first housing 1 and the second housing 2, as shown in FIG. and remove it from the recess 1b, and remove the first
The housing 1 may be moved in the direction of arrow C with respect to the second housing 2.

As described above, according to this configuration, the first casing 1 and the second casing 2 can be easily and reliably connected, and the uncoupling operation can also be easily performed. Further, since both the locking piece 3a and the locking pawl 4a can be formed integrally with the case body and the lid body, respectively, there is no need to provide separate parts. Furthermore, the lock piece 3a can be unlocked by placing your finger on the unlocking finger hook and pushing down.
The first housing 1 and the second housing 2 can be uncoupled with one hand. In addition, in the above embodiment, explanation was given by taking as an example a television receiver body and a battery case that serves as a power source for the television receiver body, but the present invention is of course not limited to this, and can also be applied to connections between other parts. It is.

As explained above, according to the present invention, a substantially L-shaped locking pawl and an elastic locking piece are each integrally formed on one housing, and the locking pawl is inserted into the other housing. By providing a hole to be fitted and a recess into which the lock piece is elastically fitted, the two casings can be easily and reliably connected. Furthermore, since both the locking pawl and the locking piece are integrally formed in the housing, there is an advantage that there is no need to provide separate parts. Further, when the connection is to be released, it is possible to release the connection between the two casings by placing a finger on the finger hook of the lock piece and pushing down, so that the connection between the two casings can be released with one hand.

Claims (1)

[Claims] 1 A plurality of substantially L-shaped locking claws and an elastic locking piece are each integrally provided on a first casing, and a plurality of locking claws are provided on a second casing that is combined with the first casing. A recess into which the lock piece fits when the locking pawl inserted into the hole moves and engages with the second casing is formed, and the lock piece has a recess that is pressed down. A housing coupling device that is integrally provided with a finger hook for unlocking, which deforms the lock piece and releases the fitted state in the recess when the lock piece is pressed.
