Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a battery mounting device that arranges a plurality of batteries in series.

[0002]

[Prior Art]

 Some electronic devices, such as cassette tape recorders, use a battery as a power source.

FIG. 5 shows an example thereof. Reference numeral 1 is a battery lid, which has a substantially L shape. The battery lid 1 is arranged in a corner portion on one end side of the cassette tape recorder and covers a battery storage portion 7 described later. This attachment or detachment is performed by sliding the battery lid 1 in the vertical direction.

A cassette unit 2 is arranged next to the battery lid 1. A cassette holder 3 is attached to the cassette unit 2 so as to tilt. The cassette T 2 is held in the cassette unit 2. Reference numeral 4 is an operation unit, 5 is a jack unit, and 6 is a speaker unit.

FIG. 6 is a sectional view of a battery mounting device of a cassette tape recorder. Reference numeral 7 denotes a battery storage portion, and the battery S has a recess for arranging a total of four vertical and horizontal two rows (in FIG. 6, a cross section in the longitudinal direction of the battery storage portion 7 is shown). The two pieces arranged in the longitudinal direction will be described below.

A terminal holding member 8 is arranged at the left end of the battery housing portion 7. A hook 9 having an L-shaped cross section is arranged on the terminal holding member 8 so as to face each other in the vertical direction. Reference numeral 10 denotes a negative electrode terminal member having conductivity, which is locked by the hook 9 of the terminal holding member 8. As shown in FIG. 6, the negative electrode terminal member 10 is formed with a spiral spring. A plate-shaped positive electrode terminal member 13 having conductivity is arranged at the right end of the battery housing portion 7. The negative and positive terminal members 10 and 13 are respectively connected to power supply terminals of a circuit (not shown).

To mount the battery S on the battery mounting device, first, for example, the first battery S (S1) is mounted on the positive electrode terminal member 13 side (right side in FIG. 6). Next, the second battery S (S2) is attached to the negative electrode terminal member 10 side (left side in FIG. 6). In this mounting, since the negative electrode terminal member 10 has a coil spring shape, the negative electrode terminal member 15 of the second battery S2 presses the negative electrode terminal member 10 toward the terminal holding member 8 side (left side in FIG. 6). Then, the positive electrode terminal 14 of the second battery S2 is brought into contact with the negative electrode terminal 15 of the first battery S1. At the time of this contact, the negative electrode terminal member 10 is always urged to the battery S side (right side), so that the pair of batteries S1 and S2 arranged in a line are contacted and held in the battery housing portion 7. It should be noted that the battery S may be attached in the same manner even if the order of attachment is reversed.

[0008]

[Problems to be solved by the device]

 By the way, as described above, in order for the pair of batteries S1 and S2 to properly contact and be held in the battery mounting device, the spring as the negative electrode terminal member 10 must be given a certain amount of resilience. However, if this resilience is too large, the positive electrode terminal 14 of the second battery S2 strongly urges the negative electrode terminal 15 of the first battery S1. Therefore, as shown by the chain double-dashed line in FIG. The vicinity of the connection between the battery S1 and the second battery S2 may rise. Therefore, in this case, it is necessary to prevent the floating portion from being lifted up by pushing down the floating portion, or the battery lid 1 must be attached with the floating portion pushed down with the finger. The installation operation of was troublesome.

Therefore, an object of the present invention is to smoothly and surely perform a battery mounting operation.

[0010]

[Means for Solving the Problems]

 In this invention, the connecting member is arranged between the batteries arranged in series.

[0011]

[Action]

 Since the connecting member 26 is arranged between the batteries S, even if a plurality of batteries S are mounted in series, the movement of the batteries S is restricted by the connecting member 26 and the battery S is fixed at an appropriate position. Therefore, even if the biasing force of the spring as the negative electrode terminal member 33, 34b is strong, the battery S will not float up. Therefore, the mounting operation of the battery S becomes smooth, and the contact and holding of the battery S can be reliably performed.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a sectional view of a battery mounting device of the cassette tape recorder shown in FIG.

As shown in FIGS. 1 and 2, the battery accommodating portion 7 recessed in the panel 20 has a recess for accommodating a total of four batteries S 2 in the vertical and horizontal rows. As shown in FIG. 2, the battery housing portion 7 has a curved surface similar to the peripheral surface of the battery S from the middle of the vertical surface 20a to the horizontal surface 20b. On the vertical surface 20a and the horizontal surface 20b, a hole 21 is formed in the center of the battery housing 7 in the longitudinal direction (left and right direction in FIG. 1), which is larger than the width of the connecting member 26 described later. The hole 21 is set to a size such that a connection member 26 to which a negative electrode terminal member 33 described later is attached can be inserted. Further, the outside (front side in FIG. 2) of the hole 21 has a structure in which the width of the connecting member 26 is approximately the same as that of the connecting member 26 (see FIG. 1). Below the outside of the horizontal surface 20b, a pair of recesses 22 is formed at appropriate portions thereof (see FIG. 1). Below the cassette holder 3, a blind plate 24 for hiding a printed circuit board 25 and the like described later is attached to a chassis (not shown). On the lower surface of the blind plate 24, a connecting piece 24a for connecting the printed circuit board 25 is projected.

On the outer side (front side in FIG. 2) of the blindfold plate 24, a connecting member 26 having a size corresponding to one battery is integrally arranged. The connecting member 26 projects only to the outside of the horizontal surface 20b while being fitted in the hole 21 of the battery housing portion 7. That is, the connecting members 26 are arranged corresponding to the outer row of the two rows of the outer side and the inner side. Therefore, as shown in FIG. 2, the connecting member 26 is not arranged in the inner (rear side in FIG. 2) row.

The connection member 26 is provided with a terminal holding member 30 and a positive electrode terminal member 31 having conductivity on one end side (left side in FIG. 1). As shown in FIG. 3, the positive electrode terminal member 31 is bent in a ring shape so that its base end portion 31b can be engaged with a hook 30a described later. The tip from this bend is formed linearly toward the center point so that it can contact the positive electrode terminal 14 of the battery S (shown by the chain double-dashed line in FIG. 3). As shown in FIG. 3, the terminal holding member 30 is provided with hooks 30a each having an L-shaped cross section in the front-rear direction. The hook 30a locks the base end portion 31b of the positive electrode terminal member 31 and also has a role of preventing the positive and negative displacement of the positive electrode terminal 14 when the battery S is mounted.

On the other end side (right side in FIG. 1) of the connecting member 26, a terminal holding member 32 and a negative electrode terminal member 33 having conductivity are arranged. The base end portion of the negative electrode terminal member 33 forms a spiral spring. The base end portion is locked by a hook 32a having an L-shaped cross section of the terminal holding member 32. The positive and negative terminal members 31 and 33 arranged on the connecting member 26 have three relay portions 27, 27 and 27 arranged on the side wall 24b of the blind plate 24 so that the respective tip portions 31a and 33a are positioned. This is done (see Figures 1 and 2). The tip portions 31a and 33a are in contact with the printed circuit board 25, as shown in FIGS.

Conductive terminal members 34 1 and 34 2 are attached to both ends (left and right in FIG. 1) of the battery housing 7. In this terminal member 34, a linear positive electrode terminal 34a and a coil spring negative electrode terminal 34b are integrally formed. The terminal members 34, 34 are attached such that the positive electrode terminal 34a and the negative electrode terminal 34b have opposite polarities (see FIGS. 1 and 2). That is, the negative electrode terminal 34b of the terminal member 34 is arranged to face one end side (the left side in FIG. 1) in the longitudinal direction of the battery housing portion 7 and face the positive electrode terminal member 31 of the connecting member 26. It is distributed. The positive electrode terminal 34a of the terminal member 34 faces a portion of the other end (right side in FIG. 1) of the battery housing portion 7 in the longitudinal direction, which faces the negative electrode terminal member 33 of the connecting member 26. It is arranged as follows.

Both ends of the linear positive electrode terminal 34a are locked by a projection-shaped stopper 24c arranged on the side wall inside the battery housing portion 7 and a groove 24d (see FIGS. 1 and 2). On the other hand, the negative electrode terminal 34b is locked by the hook 24e having an L-shaped cross section.

A stopper 35 is provided near the connecting portion of the batteries S on the vertical surface 20 a to prevent the batteries S in the inner row from floating. Further, on the side wall on the positive electrode terminal 34a side (rear side in FIG. 2) of the terminal member 34 arranged on one end side (left side in FIG. 1), there is a line for restricting the vertical movement of the positive electrode terminal 14 of the battery S. -Shaped protrusions 36 are provided so as to project vertically.

According to this example, first, in order to mount the batteries S on the inner (rear side in FIG. 2) row, for example, the positive electrode terminal 14 of the first battery S is connected to the positive electrode terminal 34 a of the terminal member 34. Contact. Next, the negative electrode terminal 34b of the terminal member 34 is pressed by the negative electrode terminal 15 of the second battery S to bring the positive electrode terminal 14 of the second battery S into contact with the negative electrode terminal 15 of the first battery S.

In addition, the batteries S are mounted on the outer (front side in FIG. 2) rows so as to be aligned with proper terminals. As a result, as shown in FIG. 4, four batteries S are connected in series and a voltage is applied to the power supply terminals 37, 37 of the printed board 25.

In the present example, even if the pair of batteries S are arranged in series on the side of the connecting member 26, the connecting member 26 is arranged at the connecting portion between the batteries S, so that the movement of the battery S is restricted and it is appropriate. It will be fixed at the correct position. Therefore, in this example, the battery S does not float, the mounting operation is smooth, and the battery S can be connected and held reliably. In this case, the pair of batteries S arranged in a line inside are pressed inward by the battery S on the connecting member 26 side, the batteries S are slightly fitted into the curved surface of the vertical surface 20a, and further lifted by the stopper 35. Since it is prevented, the battery S can be surely contacted and held.

Further, in this example, the connecting member 26 is integrally formed with the blind plate 24, and when the blind plate 24 is mounted on a chassis (not shown), the connecting member 26 is assembled, so that the connecting member 26 is separated. Assembly is easier than when assembled as a body. Further, at the time of this assembly, the tip portions 31a, 33a of the positive and negative terminal members 31, 33 are in contact with the power supply terminals 37, 37 of the printed circuit board 25. The contact can be made more easily than when connecting.

Further, in this example, when the battery S on the connecting member 26 side is detached from the battery mounting device, a finger is put in the recess 22 formed in the panel 20 and the battery S is lifted upward. By doing so, it can be easily removed.

Although the connecting member 26 is integrally formed with the blind plate 24 in the above-described embodiment, the connecting member 26 can be separately formed. Further, in the above-described embodiment, the power is supplied from the connecting member 26, but when the power is supplied from another portion, the battery S is connected by the connecting member 26.

Further, in the above-described embodiment, the batteries S are arranged in the battery housing portion 7 in the vertical and horizontal directions, but the arrangement and the number of the batteries S are not limited to this. That is, this invention can be similarly applied to any device in which a plurality of batteries are arranged in series.
