Abstract
An improved portable radio battery case and tray are shaped to conform with the radio, and permit the battery case to be easily mounted on the tray and securely held by overhangs on the tray which fit recesses 50 on one end of the battery case, and by a projection 19 on the tray which engages a groove 43 on an opposite end of the battery case. Spring loaded contacts on the tray firmly engage recessed contacts on the battery case, and also assist in securely holding the battery case on the tray. <IMAGE>
Description
SPECIFICATION
Battery cases and receptacles
Our invention relates to a battery case which fits in a battery tray of a device such as a portable radio.
At present, electronic or radio devices are being made smaller, and hence more portable.
This trend toward portability requires that many such devices be battery powered. Various arrangements have been provided to attach and connect a battery to the device.
Our invention provides an improved battery case which fits in an improved battery tray for easy connection and attachment, and for easy disconnection and removal. Our battery case is a six sided rectangular structure having recessed contacts at a first end for engaging correspondingly positioned spring loaded contacts on a first end of our tray. Our battery case has a recess around three edges of the first end for fitting within or under an overhang on the first end of our tray. At a second end opposite the first end, our battery case has a longitudinal groove which is engaged by a longitudinal projection on a second end of our tray. When our battery case is inserted into our tray, the recesses at the first end are pushed under the overhang of our tray so that the battery contacts engage and compress the tray contacts until the second end clears the projection of the tray.The battery case is then released, and the springs on the tray contacts force or maintain the groove on the case in engagement with the projection on the tray.
This engagement plus the tray overhang engaging the case recesses firmly hold the battery case in the tray. The battery case is preferably shaped so that when it is mounted on the tray, it conforms to the configuration or exterior of the radio.
By way of example only, in the accompanying drawings:
Figure 1 shows a perspective view of a radio or electronic device having a tray for use with a battery case embodying our invention;
Figure 2 shows a cross-sectional view taken along the lines 2-2 of Figure 1 to show the battery case as it is being mounted on the tray on the radio or device;
Figures 3 and 4 show respective end views of the battery case; and
Figure 5 shows a top view of the battery case.
Figure 1 shows a portable two-way radio 10 provided with a battery tray 1 The tray 11 is open at the top and is preferably made of metal and located at one end of the radio 10. The tray 1 1 includes longitudinal sides 12, 13; a first end 14 near the radio 10; a second end 1 5 opposite the first end 14; and a bottom 21. The sides 12, 13 and the second end 15 are bounded by rims 1 2a, 1 3a along the length of the sides 12, 13, and by a rim 1 5a along the length of the end 1 5 to contain a battery case. The first tray end 14 has an overhang 1 6a extending across its upper dimension, and has overhangs 1 6b, 1 6c extending along the upper portion of its vertical dimensions. Electrical contacts 17 for connection to the radio 10 are also provided at the first end 14.These contacts 17 are suitably insulated from the end 14 if necessary, and include conical wire springs 18 that urge the contacts 17 outward from the first end 14 toward the second end 15.
The contacts 17 are movable, and can compress the springs 18. The second end 15 includes a retainer 19 extending along at least a portion of rim 15a. This retainer 19 includes an inward projection 20 which, as will be explained, engages a groove in the battery case.
As shown in Figures 2 to 5 a plastic battery case 30 is a generally rectangular parallelpiped having first and second or upper and lower major sides or surfaces 31,32; first and second ends or surfaces 33, 34; and first and second sides or surfaces 35, 36. As shown in Figure 3 as well as
Figure 2, the first end 33 is provided with two recessed contacts 40 which are connected to a battery which is housed within the battery case 30. The contacts 40 are located so as to engage the tray contacts 17 to connect the battery to the radio when the case 30 is positioned in the tray 11. As shown in Figure 4 as well as Figure 2, the second end 34 is provided with recessed contacts 42 which are also connected to the battery in the case 30 to permit the battery to be changed.The contacts 42 are positioned so that this charging can take place either when the case 30 is removed or when the case 30 is in the tray 11.
The contacts 42 are positioned at different locations relative to the contacts 40 so that the battery case 30 cannot be inserted into the tray 11 or into a charger in an improper manner. The second end 34 also includes a recessed longitudinal groove 43 which is located to be engaged by the projection 20 of the retainer 19 when the case 30 is positioned in the tray 11.
The battery case 30 includes recesses 50 extending around the three edges formed at the intersection of the first end 33 with the upper surface 31 and with the sides 35, 36. These recesses 50 are dimensioned so that they fit within or under the tray overhangs 16a, 16b, 16c.
Also, the battery case 30 is provided with recesses 53 extending along the two edges at the intersection of the lower surface 32 with the sides 35, 36. These recesses 52 are arranged to permit the battery case to rest on the rims 12a, 13a of the tray sides 12,13.
When the battery case 30 is to be connected to and mounted on the tray 11, it is positioned substantially as shown in Figure 2. It is tilted so that the recesses 50 fit under and within the overhangs 1 6a, 1 6b and 16c, and is then pushed toward the radio 10 so that the contacts 40 engage the contacts 17 to urge the contacts 17 against the springs 18. The battery case 30 is then rotated as indicated by the arrow 60 in
Figure 2 so as to permit the end 34 to clear the projection 20. The battery case 30 is moved until the recesses 52 engage the rims 12a, 13a, and the upper surface 31 is flush or parallel with the upper surface of the radio 10. The battery case 30 is then released so that the springs 18 urge the battery case 30 away from the radio 10 and so that the projection 20 fits in the groove 43.When the battery case 30 is so positioned, it is firmly held by engagement of the recesses 50 under or within the overhangs 1 6a, 1 6b, 1 6c, and by engagement of the projection 20 in the groove 43. The recesses 52 also provide additional retention by their engagement with the rims 12a, 13a. The parts are so dimensioned or structured that when the battery case 30 is in its mounted position, there is still some force being exerted by the springs 18 to cause firm engagement of the tray contacts 1#7 with the battery contacts 40.
Also, when the battery case 30 is in its mounted position, its outer surfaces preferably conform with the radio 10 to provide a conforming or similar appearance. When the battery case 30 is removed, the reverse procedure is followed. This is achieved by moving the battery case 30 toward the radio 10 to compress the springs 18 until the second end 34 can be moved clear of the projection 20, after which the battery case 30 is removed.
It will thus be seen that we have provided a new and improved battery case and tray which can be shaped to conform with a radio or the like, and which permit easy mounting and connection of the battery case with the tray, and which permit easy disconnection and removal of the battery case from the tray. While we have shown our tray 11 and our battery case 30 with relatively sharp corners and edges, persons skilled in the art will appreciate that some of the corners and edges may be rounded, particularly those which face outward. Multiple projections and grooves can be used in place of one projection, and flat contact springs can be used in place of conical wire springs. Also, the depth of our battery case 30 below the recesses 52 may be varied, depending on how much room is to be provided for components positioned on the bottom 21 of the tray 11.
