Figure 3 shows the battery and the battery according to the invention. a locking member 300 for a battery, the locking member 300 having two ribs 301 and 302 arranged in the longitudinal direction of the locking member 300 in the exemplary embodiment. The ribs 301 and 302 are substantially perpendicular to the plane of the rear panel of the housing. Optionally, the ribs 301 and 302 may, in various embodiments, have an angle other than perpendicular to the plane of the housing which does not affect operation or effect in any way. In the exemplary embodiment, it is also noted that the ribs 301 and 302 are arranged such that their height increases to the rear face of the battery housing from the edge of the housing cover 303. Embodiments may be provided where one or more ribs are used.

At the farthest point from the edge of the lid 303, the ribs 301 and 302 are provided with projections 304 and 305 which are in the same plane as the ribs 301 and 302, but extend higher than the ribs 301 and 302. These projections 304 and 305 extend from and are connected to the ribs 301 and 302 along a curved surface. The connecting surface is at an angle of approximately 45 ° to the vertical plane. Embodiments where this angle is set to a different value, or alternatively, the ribs 304 and 305 may be provided with a connection angle of 90 ° to the ribs 301 and 302, may be provided.

The portion of the projections 304 and 305 extending toward the end of the locking member 300 is cut off at an angle of 90 °. Of course, this angle may also be different from 90 ° for different embodiments.

The locking member 300 of the battery housing part is surrounded by a cut-out 310 such that the locking member 300 is only a thin, predetermined thickness or width to the cover 303. it is connected by a band of adjustable thickness 311 which, in the exemplary embodiment, is disposed in the transverse axis of the locking member 300 and is slightly inclined. The strip 311 is also made by casting to produce the locking member 300 and the housing 350.

The strip 311 of material 311 bridgingly engaging the locking member 300 on the housing 350 allows the locking member 300 to rotate slightly to the transverse axis of the housing. When the lid 201, shown in Figure 2, is pressed against the locking member 300 at the rear of the housing, the projections 304 and 305 are slightly elevated as the front portion of the locking member 300 is subjected to pressure and the locking member 300 is pressed. 302 ribs slightly rotate. As will be described later, this rotation facilitates the removal of the housing 350 for the battery from the housing 200 of the radiotelephone, i.e., the system is opened.

Figure 2 illustrates a locking member 230 of a housing part of a radiotelephone. The back of the housing containing the radiotelephone is provided with a recess 210 which forms a pocket-like recess which protrudes from the backside of the radiotelephone housing. This recess 210 is arranged so as to face the cover of the cellular phone housing. The leading edge 420 of the aforementioned recess 210, shown in Figure 4.1, forms an angle of 45 ° with the vertical. This front edge 420 contacts the front edge of the locking member 300 formed on the battery housing as it slides into place. The recess 210 is sized to be just large enough to accommodate the projections on the locking member of the battery housing.

The size tolerance of the recess 210 should be small, since the locking member 300 of the battery housing should not have a free space to rotate. This is the connection or connection. it causes locking noise when the wireless phone is moved and, moreover, its appearance is less favorable.

The battery housing 350 and the cellular telephone 200 housing each have 220 and 220 respectively. There are 320 connecting rails, which are 200 and 200 rails, respectively. the houses 350 are guided relative to one another. The 200 and 200 respectively. The 350 and 220 housings on the 350 housing. 320 connectors

The rails 7 are formed as protrusions extending essentially on the side of the surface. The connecting rails 220 and 320 are arranged on each of the housings 200 and 350 so that the battery housing 350 is under the terminal 220 of the cellular telephone housing 200 when the two housings 200 and 350 are connected and in contact with each other. This allows the two housings 200 and 350 to move forward and backward along the longitudinal axis of the radiotelephone only along this axis.

During operation, the housing 350 associated with the battery is connected to the housing 200 of the radiotelephone such that the housing 220 and 220 are respectively connected. 320 connecting rails are interconnected. Subsequently, the battery housing 350 is simply moved backward in the cellular telephone housing 200 so that the lid 303 of the battery 350 is in contact with the lid 403 of the cellular telephone 200. This sequence of motion can be seen in Figure 4.1.

When the leading edges 410 and 420 of the projections 411 are disposed at a given angle and the recess 210 contacts one another as shown in Figure 4.2, the locking member 300 of the battery housing 350 is forced to rotate at the top of the projections 304 and 305. The locking member 300 for the housing 350 will rotate about the intersection of the leading edge 420 of the recess 210 with the ribs 301 and 302 for the housing 350. It can be seen in Figures 4.1, 4.2 and 4.3 that, at a given angle for recess 210, as an example! 45 struck ^this embodiment at an angle of 420 leading edge 300 on the cover 410 and the front edge forming a smooth transition for the entire locking member 300 and the closure. during the connection. If the leading edges 410 and 420 were to be angled 90 degrees to the horizontal plane, much more force would be required to engage the locking member 300 in place.

Figure 4.3 shows the situation where the battery housing and the cellular phone housing are connected. The battery latch member extends

- The 8 tabs will be located in the recess of the locking element of the cellular phone housing. The vertical wall 430 of the rear portion of the battery housing latch member contacts the rear wall 431 of the radiotelephone latch member. By contacting the rear walls 430 and 431, the battery housing is much more difficult to remove, since the connecting rails only allow the cover and the housing and the radiotelephone housing to move relative to each other forwards and backwards. In the embodiment shown here, the rear walls 430 and 431 resist such movement. At the top of the rear wall, a projection is formed at an angle of 77 ° to reduce deformation of the locking element when the outside of the radio is exposed.

To separate the battery housing from the cell phone housing, press the front of the locking element at the cell phone housing. As a result, the battery housing latch member can rotate around the joint of the ribs and recesses formed on the battery housing latch member. This rotational movement lifts the projections 304 and 305 out of the recess 210 and allows the housing 350 of the battery to extend 320 and 325 respectively. Slide backwards along 220 connecting rails and then freely lift the battery housing out of the cellular phone housing.

Figures 5.1, 5.2 and 5.3 show another embodiment. Also in this embodiment, a recess 504 is provided and the connecting rails are provided. In addition, the latch member for the battery housing is attached to the battery housing in the same pivoting manner as in the previous embodiment. However, in this embodiment, the ribs that are extending longitudinally of the battery housing are replaced by two shorter elastic ribs 500 having a thickness substantially equal to that of the ribs 301 and 302 used in the previous embodiment. The figure shows a single rib 500. The elasticity of the 500 ribs is guaranteed by * · · · · · ·

9 that a cutout 501 is formed in the longitudinal direction of the rib 500. In this embodiment, the leading edge 502 of the recess 504 forces the ribs 500 to contract upwards, as shown in Figure 5.2. The battery housing will then lock or unlock. closes when the top 503 of the rib 500 enters the recess 504, as shown in Figure 5.3. By depressing the recess 504 slightly upwardly, the rib 500 cannot extend or extend again. expand in its original position as shown in Figure 5.1. The rib 500 is held in place by the downward pressure exerted by the top 503 on the recess 504 so that the battery housing is locked in the correct position.

The locking element according to the invention makes it possible to connect the locking elements produced by casting together with the housing of each element. In this way, both production and manufacturing costs can be significantly reduced.
