That is, when the battery pack 100 is mounted on the battery mounting portion 10, the back surface (left surface) 106a of the rear case 106 contacts the bottom surface 15 of the battery mounting portion 10 (see FIG. 15), and the battery pack 100 side The locked portions 112 (the right end portions 109a of the terminal positioning ribs 109, the small recessed portions 113 and the locked grooves 114) at the respective locations correspond to the corresponding locked portions on the battery mounting portion 10 side (eaves portion 17, small protruding portion 20 and This is done by being locked to the lock claw 41), but the plurality of locked parts 112, 11
When 2, ... Are provided in separate parts such as the rear case 106 and the front case 105, the back case 106 and the front case 105 are loosely assembled unless they are assembled accurately. At the same time, a problem occurs in the connection state between the battery side terminal 120 and the main body side terminal 30.

Therefore, like the battery pack 100 described above, by positioning the locked portions 112 for positioning as described above in one component (rear case 106), the positioning of the battery pack 100 in the mounted state is performed. Can be made highly accurate, and thus, the accuracy of combination of the rear case 106 and the front case 105 can be made rough.

A recess 11 that is substantially flush with the recess 107 of the rear case 106 is formed in the front portion of the upper surface of the front case 105 corresponding to the battery-side terminals 120.
5 is formed, and a terminal pressing rib 116 that presses the battery side terminal 120 from the right side is formed on the left edge of the recess 115 (see FIGS. 7 to 9).

The length of the terminal pressing rib 116 in the front-rear direction is determined by the two terminal positioning ribs 1 of the rear case 106.
09, 109, that is, the battery side terminal 1
The terminal pressing rib 116 is formed between the two terminal positioning ribs 109, 109 when the front case 105 is assembled to the rear case 106. While pressing the battery side terminal 120 from the left side, the rear case 10
The two terminal positioning ribs 109, 109 of 6 project slightly to the right of the terminal pressing rib 116, and serve as the locked portions 112, 112 as described above (see FIG. 8). ).

In such a standard capacity type battery pack 100, two flat rectangular parallelepiped battery cells 102, 102 are housed side by side in a battery case 101, and the substrate 104 is attached to the upper part thereof. , The battery side terminal 120 on the front side portion of the substrate 104.
However, the IC chip 103 and the like are mounted on the rear portion (see FIG. 4).

As described above, since the battery-side terminal 120 is arranged at a position biased to one side with respect to the battery pack 100, a relatively large space can be provided on the opposite side. The electronic parts such as the IC chip 103 can be arranged, and the space efficiency can be improved. In particular, when the battery cell 102 has a flat rectangular parallelepiped shape, no dead space is formed when the battery cell 102 is arranged in the battery case 101, and the battery cells 102, 102 can be efficiently arranged as the battery pack 100. On the other hand, it is difficult to secure a space for disposing the battery-side terminal 120, the IC chip 103 on the substrate 104, and the like protruding from the battery cell 102. However, as described above, the battery-side terminal 120 is provided with respect to the battery pack 100. The space can be effectively used by arranging it in a biased position (see FIGS. 4 and 7).

By providing the battery-side terminal 120 at a position offset from the battery pack 100,
It is also possible to prevent erroneous mounting in mounting on the camera body 2.

The detailed shapes of the battery-side terminal 120 and the rectangular cutout 108 on the receiving side thereof and the method of assembling the two will be described later in detail.

Next, the battery mounting portion 10 of the camera body 2
Will be described in detail.

The dimension up to the bottom surface 15 of the battery mounting portion 10 of the camera body 2 is formed to be slightly larger than the thickness (thickness in the left-right direction) of the back case 106 of the battery case 101, whereby the battery pack 100 is used as a battery. When mounted on the mounting portion 10, the rear case 106 is located inside the battery mounting portion 10, and most of the front case 105 projects from the camera body 2 (see FIGS. 3 and 15). ).

The body side terminal 30 is the battery side terminal 12
The position facing 0, that is, the inner surface (lower surface) of the upper frame 13
It is a corner between the bottom surface 15 and the bottom surface 15 and is provided at a position on the diagonally upper front side (see FIG. 10).

An eave portion 17 protruding downward is formed at the opening side edge (right side edge) of the inner surface 13a of the upper frame 13 corresponding to the position where the main body side terminal 30 is provided. The dimension between the eaves portion 17 and the bottom surface 15 of the battery mounting portion 10 is formed to be the same as the dimension between the back surface 106a of the back case 106 and the right end portion of the terminal positioning rib 109 (see FIG. 15). .

As a result, when the battery pack 100 is mounted on the battery mounting portion 10 and the right end portion 109a of the terminal positioning rib 109 is locked to the eaves portion 17, there is no rattling between the two and therefore, in the mounted state. The upper front part of the battery pack 100 is locked without rattling (see FIG. 15).

The small protrusion 18a formed in the vicinity of the blocking protrusion 18 and the main body side terminal 30 described later serves as a blocking portion 19 for determining whether or not the battery pack 100 can be mounted, as described later. In addition, in the video camera 1, since the blocking unit 19 does not interfere with the discriminator 111 of the battery pack 100, the mounting of the battery pack 100 in the battery mounting unit 10 is “OK”. In such a device to which the battery pack 100 is attached, for example, the video light 150 (which cannot be attached to the low-capacity battery pack 100), the attachment is “impossible” due to the difference in the capacity of the battery pack 100. In some cases.

In this case, the blocking portion 19 extends to the vicinity of the bottom surface 15 of the battery mounting portion 10 and the discriminator 111.
Some of them interfere with and prevent the installation.
Whether or not the battery pack 100 can be mounted is determined by the discriminator 111 and the blocking unit 19 on the battery pack 100 side.
The shape and the positional relationship between and are described later in detail.

The inner surface (lower surface) 13a of the upper frame 13 of the battery mounting portion 10 and the inner surface (front surface) 12 of the rear frame 12

Further, the lock lever 42 and the push-up plate 4
3. The coil portion 48a of the torsion coil spring 48 is externally fitted to the rotation shaft 47 that rotatably supports the pop-out prevention lever 44, and one arm portion 48b of the torsion coil spring 48 is attached to the lock lever 42 and the other arm. The portion 48c acts on the push-up plate 43, whereby the lock lever 42 is biased upward and the push-up plate 43 is biased rightward (see FIG. 12).

The lock lever 42 has a laterally L-shape as a whole, and an upper surface piece 49 thereof is formed so as to form a part of the inner surface (upper surface) of the lower frame body 14. A lock claw 41 having a triangular cross-section extending in the front-rear direction is formed at a position near the center of motion, and an operating portion 50 for operating the lock lever 42 is formed on the lower right side surface (see FIGS. 11 and 12). ).

The lock claw 41 is formed at a position slightly rightward (front side) from the bottom surface 15 of the battery mounting portion 10, and the distance from the bottom surface 15 is the locked position of the battery pack 100. Bottom surface 106a of groove 114
The distance from the battery pack 100 is the same as that of the battery pack 100. When the lock claw 41 engages with the locked groove 114, the battery pack 100 is pressed against the bottom surface 15 of the battery mounting portion 10 (see FIG. 15). ).

Further, small projections 51, 51 which come into contact with the edges of the lock lever disposing hole 22 of the lower frame 14 are formed on both left and right sides of the upper surface piece 49 of the lock lever 42, respectively. Collides against the edge of the lock lever disposing hole 22 from the inside, so that the rotational bias by the torsion coil spring 48 is blocked, and in this state, the upper surface of the upper surface piece 49 is flush with the upper surface of the lower frame body 14. It is supposed to be.

Small pieces 52, 52 projecting downward from the center of rotation are integrally formed on the push-up plate 43. When the small pieces 52, 52 come into contact with the base plate 45, the small pieces 52, 52 are rotated by the torsion coil spring 48. The urging is blocked, and in this state, the push-up plate 43 is in a state of protruding to the right of the push-up plate disposition hole 21 (see FIG. 12).

The pop-out prevention lever 44 has a compression coil spring 54 contracted between the lower surface of the pivot end and the projecting piece 53 formed on the base plate 45, whereby the pop-out prevention lever 44 is locked. Like the lever 42, it is urged to rotate upward (see FIGS. 13 to 16). 13 to 16, the battery-side terminal 120 and the body-side terminal 30 are omitted.

A claw portion 55 projecting upward is formed at the rotating end of the pop-out prevention lever 44, and a rotation preventing piece 56 projecting forward is integrally formed at the base end thereof. When the rotation blocking piece 56 collides with the restraining piece 57 formed on the base plate 45, the rotation bias by the compression coil spring 54 is blocked, and in this state, the claw portion 55 moves upward from the upper surface of the lower frame body 14.

When the battery pack 100 is mounted on the battery mounting portion 10, the following procedure is performed.
The installed battery pack 100 has the lock mechanism 40.
Thus, the battery mounting portion 10 is held in a locked state.

First, with the upper part of the battery pack 100 tilted to the left, it is inserted into the battery mounting portion 10 and the battery side terminals 120 (the terminal positioning ribs 109 of the rear case 106 and the terminal pressing ribs 116 of the front case 105) are inserted.

The battery pack 1 will be described in detail later.
The discriminator 111 on the 00 side and the blocking portion 19 on the battery mounting portion 10 side are formed so as to interfere with each other, so that the battery side terminal 120 is connected to the eaves portion 17 of the battery mounting portion 10.
It is not possible to make it penetrate into the interior of the battery, so that the terminal member 122 of the battery side terminal 120 and the terminal piece 31 of the main body side terminal 30 are not joined.

Further, even if the blocking portion 19 of the battery mounting portion 10 and the discriminator 111 of the battery pack 100 interfere with each other,
When the battery pack 100 is forcibly attached, the discriminator 111 presses the blocking portion 19 to bend the upper frame 13 of the battery attachment portion 10, and the attachment may be “permitted”. There might be one.

However, even in such a case, the blocking unit 1
Since 9 and the discriminator 111 are formed near both terminals 120 and 30, when the blocking portion 19 is pressed, the main body side terminal 30 is pressed and escapes in the pressing direction.
The terminals 120 and 30 are not joined together, and the terminal piece 31 and the terminal member 122 are not brought into contact with each other after all,
Electrical contact can be avoided.

Next, the lower part of the battery pack 100 is rotated to the left with the upper part of the battery pack 100 (the battery side terminal 120 part locked to the eaves 17) as the fulcrum of rotation, and the battery pack 100 is attached to the battery mounting part. 10 (see FIGS. 14 and 15).

At this time, after the claw 55 of the pop-out prevention lever 44 of the lock mechanism 40 is kicked downward at the lower left side edge (bottom side corner) of the battery pack 100, the claw 55 is removed from the battery pack 100. It engages in the locked groove 114 of 100 (see FIG. 14).

When the lower portion of the battery pack 100 is further pressed toward the battery mounting portion 10, the claw portion 55 of the pop-out prevention lever 44 is kicked by the edge portion of the locked groove 114 and the lock lever 42 of the lock lever 42 is pushed. Lock claw 4
1 is kicked downward by the lower left edge (bottom side corner) of the battery pack 100, and then the lock claw 41 is engaged in the locked groove 114, and the mounting of the battery pack 100 is completed ( (See FIG. 15).

Further, prior to the engagement of the lock claw 41 with the locked groove 114, the bottom surface 106a of the battery pack 100.
Rotates the push-up plate 43 to the left, so that the bottom surface 106 a of the battery pack 100 becomes the bottom surface 1 of the battery mounting portion 10.
5 is almost in surface contact (see FIG. 15).

The lock lever 42, the pop-out prevention lever 44 and the push-up plate 43 are rotated against the elastic force of the torsion coil spring 48 or the compression coil spring 54.

At this time, the terminal member 122 of the battery side terminal 120 and the terminal piece 31 of the main body side terminal 30 are joined together, and the right end portion 109a (of the terminal positioning rib 109 provided on the upper portion of the battery pack 100 ( The locked portion 112) is engaged with the eaves portion 17, and the small recess 113 (locked portion 112) of the battery pack 100 is connected to the battery mounting portion 10.

As a result, in the upper part of the battery pack 100, the right end portion 109a of the terminal positioning rib 109 is formed.
The (locked portion 112), the eaves portion 17, the small concave portion 113 (locked portion 112) and the small convex portion 20 are engaged with each other, and in the lower portion of the battery pack 100, the lock claw 41 and the locked groove 114. When the and are engaged, the battery pack 100 is held in the battery mounting portion 10 (see FIG. 15).

The lock claw 41 of the lock lever 42 and the claw portion 55 of the pop-out prevention lever 44 are attached to the battery pack 100.
Is pressed upward to press the battery pack 100 against the upper frame body 13, and the battery pack 100 is positioned in the vertical direction (see FIG. 15).

As a result, the battery side terminal 120 is pressed against the main body side terminal 30, and a stable terminal member 122 is formed.
The joined state between the terminal piece 31 and the terminal piece 31 is maintained. Particularly, the battery side terminal 120 and the main body side terminal 30 are the battery pack 10
Although it is provided at a position biased forward with respect to 0, the pop-out prevention lever 44 is also provided at a position biased forward of the central portion in the front-rear direction, that is, facing both terminals 120, 30. Position preventive lever 44
Since the claw portion 55 is provided, the battery pack 100 is pushed upward, and the terminal member 122 and the terminal piece 31 are secured in a reliable joined state (see FIG. 2).

The lower part of the battery pack 100 is pressed to the right by the push-up plate 43 and is blocked by the engagement of the lock claw 41 and the locked groove 114. The battery pack 100 is positioned in the mounting direction (left-right direction), and when the battery pack 100 is mounted on the battery mounting portion 10, the inner surface (rear surface) 11a of the front frame body 11 and the rear frame body 1 are mounted.
Small ribs 16 and 1 formed on the inner surface (front surface) 12a of 2
Since it is regulated by 6, ..., Positioning is performed in the front-back direction (see FIG. 3).

The battery pack 100 mounted on the battery mounting portion 10 of the camera body 2 in this manner is removed as follows.

That is, first, the operating portion 50 of the lock lever 42 is pressed by a finger or the like to unlock the lock mechanism 40 (see FIG. 16).

When the lock lever 42 is operated, the lock lever 42 is rotated downward against the elastic force of the torsion coil spring 48, whereby the lock claw 41 is disengaged from the locked groove 114 of the battery pack 100. .

When the lock claw 41 is unlocked from the battery pack 100, the lower part of the battery pack 100 is pushed leftward by the push-up plate 43, and the battery pack 100 floats up from the bottom surface 15 of the battery mounting portion 10 (see FIG. 16). ).

At this time, when the lower portion of the battery pack 100 is slightly lifted from the bottom surface 15 of the battery mounting portion 10, the claw portion 55 of the pop-out prevention lever 44 fits into the locked groove 114 of the battery pack 100. This allows
Although the battery pack 100 floats from the battery mounting portion 10, the claw portion 55 of the pop-out prevention lever 44 is not caught by the locked groove 114 and the battery pack 100 does not pop out carelessly. In particular, when the video camera 1 is oriented in the above-described orientation (the orientation in the normal shooting state), even if the lock of the battery pack 100 is released, the claw portion 55 of the pop-out prevention lever 44 is caught in the locked groove 114, The battery pack 100 does not come off from the battery mounting portion 10, and the battery pack 100 can be prevented from falling.

Next, by gripping the battery pack 100 whose lower part is lifted with fingers or the like and pulling it out in the detaching direction (rightward), only the claw portion 55 of the pop-out prevention lever 44 and the locked groove 114 are engaged. So battery pack 1
00 can be easily detached from the battery mounting portion 10.

Next, the details of the battery side terminal 120 and the assembling of the battery side terminal 120 to the battery pack 100 will be described.

As described above, the battery side terminal 120 is composed of the terminal case 121 and the terminal members 122, 122, 122 provided by insert molding on the terminal case 121. The terminal case 121 has a flat rectangular parallelepiped block shape. Five grooves 123, 12 which are present and open on the upper surface and the left surface

Therefore, when the contact portion 35 is inserted into the terminal disposing groove 124, the contact convex portions 125a, 125
5a, only contact the contact portion 35
Even if the contact portion 35 is inserted into the terminal placement groove 124 from either of the directions (left and right direction and up and down direction), the contact piece 12
The spring characteristics of 5 and 125 are the same, so both terminals 1
The contact stability of 20 and 30 can be secured. Of course, this effect is obtained when attention is paid only to the terminal structure, and with respect to the mounting of the video camera 1 and the battery pack 100 in the above-described embodiment, only insertion from the left and right directions is performed.

The base piece 127 is exposed so as to be adhered to the right side surface of the terminal case 121, and the lead piece 128 extends from the lower edge of the base piece 127 and is bent at a right angle so as to be bent. It is substantially flush with the bottom surface 121a and extends to the right (see FIGS. 20 and 21).

Slide protrusions 129 and 129 extending in the left-right direction are formed on both front and rear surfaces of the terminal case 121, and the slide protrusions 129 and 129 are front and rear edges of the rectangular cutout 108 of the rear case 106, respectively. The battery side terminal 120 is supported by the rear case 106 by being slidably fitted in the slide grooves 117 and 117 formed on the lower side of the positioning rib 109 (see FIG. 9).

The left ends of the slide grooves 117 and 117 of the rear case 106 are closed, so that the battery-side terminals 120 are positioned to the left when they are slid. That is, the rear case 1
The position from the back surface 106a of 06 to the battery side terminal 120 is regulated.

A kerf 130 is formed at the corners of the right side surface and the front side surface and the right side surface and the rear side surface of the terminal case 121, adjacent to the upper side of the slide protrusions 129 and 129.
130 is formed, and the cut grooves 130, 130 are fitted with projections 118, 118 provided to the left from the front and rear end portions of the terminal pressing rib 116 of the front case 105 (FIG. 9). reference).

Then, such a battery side terminal 120
Are the three lead pieces 128, 128, 128 are the above-mentioned substrate 1
The battery side terminal 120 is mounted on the front left corner of the substrate 104 by soldering at a predetermined position (front left corner) 04 (see FIGS. 4 and 7). Further, electronic components such as the IC chip 103 are mounted on the substrate 104 at a predetermined position on the rear side where the battery side terminals 120 are not mounted (see FIG. 7).

Then, the battery pack 100 is assembled as follows.

That is, the two battery cells 102, 1
02 are connected in a front-rear side-by-side state, and the battery-side terminals 12 are provided above the battery cells 102, 102.
0, the IC chip 103, and other substrates 104 are mounted (see FIG. 4).

Next, the battery cells 102, 102 to which such a substrate 104 is attached are inserted into the rear case 106 from the right side thereof. At this time, the battery side terminal 120
Is inserted into the rectangular notch 108 of the rear case 106 while sliding from the right side (see FIG. 7).

Then, as described above, the battery side terminal 1
20 slide protrusions 129 and 129 are attached to the rear case 106.
The slide grooves 117 and 117 are inserted (see FIG. 7).

Finally, the front case 105 is aligned with the rear case 106 so as to cover the battery cells 102, and both are joined (see FIG. 8).

At this time, the protrusion 11 of the front case 105
8, 118 cut grooves 130, 130 of the rear case 106
While fitting in, the right side of the terminal case 121 is pressed by the terminal pressing rib 116, and the base pieces 127, 127, 127 of the terminal member 122 exposed on the right side are covered up. The battery side terminal 120 is positioned in the left-right direction so as to be sandwiched between the rear case 106 and the front case 105.

The front case 105 and the rear case 106 are joined together by ultrasonic welding in a state where the peripheral edges of the openings are aligned. It should be noted that the adhesion is not limited to ultrasonic welding and may be adhesion using an adhesive.

As described above, the battery pack 100 includes the rear case 106, the battery cells 102 (including the battery side terminals 120, the board 104, etc.) and the front case 105.
It is possible to construct the above three parts only by assembling from one direction.

Next, details of the connection between the main body side terminal 30 and the battery side terminal 120 will be described.

First, the body side terminal 30 is connected to the battery mounting portion 1
0 of the above-mentioned position (corner part on the front bottom surface side of the upper frame body 13), and the three terminal pieces 31, 31, 31 standing upright from the bottom surface 15 and the lower surface 13a of the upper frame body 13, and these. Two guide pieces 32, 32 provided so as to sandwich the terminal pieces 31, 31, 31 from the front and rear sides, and rotatably provided on the upper frame 13 so as to cover the upper side of each terminal piece 31, 31, 31. The protective plate 33 is provided (see FIGS. 22 and 23).

The terminal piece 31 is in the shape of a rectangular flat plate when viewed from the front-rear direction, its upper edge and left edge are embedded in the upper frame body 13, and the lead portion 34 protruding upward from the upper frame body 13.
Is provided (see FIG. 24), and the portions exposed from the upper frame 13 (lower edge and right edge) are the battery-side terminals 120.
Is a contact portion 35 sandwiched between the contact pieces 125, 125, and the end side edge of the contact portion 35 is chamfered.

The three terminal pieces 31, 31, 31 are the terminal arrangement grooves 124, 12 of the battery side terminal 120.
4 and 124 are formed at the same formation intervals as each other, and the plate thickness of each terminal piece 31 is formed to be approximately half the groove width of the terminal arrangement groove 124 formed in the battery side terminal 120 (FIG. 22, (See FIG. 23).

Like the terminal piece 31, the guiding piece 32 has a rectangular shape when viewed from the front-rear direction, and is integrally formed with the upper frame 13 and the bottom surface 15 of the battery mounting portion 10 (see FIG. 24).

The guide pieces 32, 32 are larger than the contact portion 35 of the terminal piece 31 as viewed from the front-rear direction, and the plate thickness thereof is formed thicker than the terminal piece 31. Guide grooves 123, 12 formed
The guide pieces 3 are formed at the same formation intervals as those of the guide pieces 3.
The plate thicknesses of 2, 32 are formed to be slightly smaller than the groove widths of the guide grooves 123, 123 of the terminal case 121 of the battery side terminal 120, and the end side edges of the guide pieces 32, 32 are chamfered. (See FIG. 23).

Since the guide piece 32 is formed larger than the contact portion 35 of the terminal piece 31 as described above, when the guide piece 32 is connected to the battery-side terminal 120, the contact portion 35 is inserted before entering the terminal arrangement groove 124. The guide piece 32 is inserted into the guide groove 123 (see FIG. 2).
6).

The protective plate 33 is supported on the front end of the inner surface (lower surface) of the upper frame 13 so as to be vertically rotatable at a position near the opening side edge (right side edge) (see FIGS. 24 and 25). .

Specifically, a concave protective plate housing 13b is formed at the front end of the inner surface (lower surface) of the upper frame 13.
In addition, on both front and rear edges of the protection plate 33, support shaft protrusions 36, 36 that are rotatably fitted to both right end portions of the protection plate storage portion 13b are integrally formed, and the front support shaft protrusion is provided. A torsion coil spring 37 is provided in the portion 36, and the protection plate 33 is biased in the counterclockwise direction when viewed from the rear (see FIGS. 24 and 25).

Rotation blocking portions 38, 38 (only one is shown in the drawing) are provided at the rotation fulcrum portion of the protection plate 33 so as to come into contact with the upper frame 13 and prevent the rotation in the counterclockwise direction. The protective plate 33 is a counterclockwise rotating end at the position where the rotating end thereof is directed obliquely downward to the left (approximately 45 °) (FIG. 10A, FIG. 24, FIG. 24). Two
9). The clockwise rotation end of the protection plate 33 is a position where the protection plate 33 is housed in the protection plate housing portion 13b of the upper frame body 13, and is a substantially horizontal position (FIG. 10B). reference).

The size of the protection plate 33 in the front-rear direction is slightly smaller than the distance between the two guide pieces 32, 32, and is always rotatable between the two guide pieces 32, 32. Slits 39, 39, 39 are formed at the positions corresponding to the terminal pieces 31 and open to the side edge of the rotation end, so that when these are rotated upward, the slits 39, 39, 39 are provided with respective slits 39, 39, 39. Terminal pieces 31, 31,
31 is inserted to allow the rotation of the protection plate 33, and the terminal pieces 31, 31, 31 are exposed when the protection plate 33 is rotated (see FIGS. 10, 22, and 23). 10A shows a state where the protection plate 33 is rotated, and FIG. 10B shows a state where the protection plate is not rotated.

When no external force is applied to the protection plate 33, the corner portions of the two guide pieces 32, 32 are located at the turning end of the protection plate 33 in the counterclockwise direction and rotate. Both sides of the moving edge are covered from the front and back (see FIG. 24), and in this state, the contact portion 3 of each of the terminal pieces 31, 31, 31 is
The corners of 5, 35, and 35 are the slits 39, 39, and 3 described above.
It is in a state of being slightly fitted in the inside 9 (see FIG. 25).

As will be described later in detail, when the battery pack 100 is mounted on the battery mounting portion 10, the terminal case 121 of the battery side terminal 120 presses the protection plate 33, and the elastic force of the torsion coil spring 37 is exerted. Against this, the protection plate 33 rotates clockwise and is positioned in the protection plate storage portion 13b of the upper frame 13 (FIG. 29).
reference).

As a result, the contact portions 35, 35, 35 of the main body side terminal 30 are exposed and relatively penetrate into the terminal disposing grooves 124, 124, 124 of the terminal case 121 to make a pair of contact pieces 125, 125. It is sandwiched between the two and makes electrical contact (see FIG. 28).

As described above, the protection plate 33 is in contact with the contact portions 35, 3 when the external force is not applied.
Since it covers 5 and 35, the contact portion 3
It is possible to prevent foreign matters from adhering without exposing 5, 35 and 35 (see FIG. 25).

Further, a member other than the battery-side terminal 120 collides with the body-side terminal 30 when the body-side terminal 30 collides with the body-side terminal 30 for some reason, for example, when the battery pack 100 is about to be mounted in the wrong direction (misplaced). there is a possibility.

Even in such a case, the guide piece 32,
Since 32 is formed larger than the contact portions 35, 35, 35, its external force mainly acts on the guide pieces 32, 32, and the external force does not act directly on the contact portions 35, 35, 35. Contact parts 35, 35, 35
To prevent deformation.

Further, a relatively small foreign matter is not detected by the main body side terminal 3.
When it collides with 0, the protective plate 33 is present, so that it collides with the protective plate 33 before the terminal piece 31 (contact portion 35), and the external force is relaxed.
No large external force is directly applied to the contact portion 35.

Further, as described above, since the protective plate 33 is provided in a state of being sandwiched between the two guide pieces 32, 32, an external force having a component in the front-back direction is applied to the protective plate 33. At this time, the guide pieces 32, 32 act so as to support the protective plate 33, and further, the three contact portions 35, 35, 35 are inserted into the three slits 39, 39, 39 as described above. When the protective plate 33 is displaced in the front-rear direction, the external force is applied to the three contact portions 35 via the slits 39, 39, 39.
Since it is applied to 35, 35, an external force is not concentrated on one contact part 35, and also from this point, the deformation of the contact parts 35, 35, 35 can be prevented.

The main body side terminal 30 as described above is provided on the corresponding portion of the upper frame 13 with the guide piece 3 as in the above embodiment.
2, 32 may be integrally formed, the terminal pieces 31, 31, 31 may be integrally formed by insert molding, and the protection plate 33 may be rotatably provided, or a predetermined shape as a separate member. Each part is molded or formed on the base member of the upper frame body 13 and the separate member is used as a terminal assembly.
It may be attached to.

Next, the connection between the battery side terminal 120 and the main body side terminal 30 by mounting the battery pack 100 on the battery mounting portion 10 will be described.

First, as described above, the battery pack 100 has the battery side terminal 120 with respect to the battery mounting portion 10.
The terminal positioning rib 109 and the terminal pressing rib 116 are obliquely positioned so as to be submerged in the eaves portion 17 of the upper frame body 13, and the main body side terminal 30 and the battery side terminal 120 are opposed to each other.

Next, the battery side terminal 12 is attached to the eaves section 17.
When 0 is dipped (see FIG. 13), the guide pieces 32, 32 of the main body side terminal 30 are moved to the guide groove 123 of the battery side terminal 120,
It is relatively inserted in 123 (see FIG. 26). At this time, the opening side edges of the guide grooves 123, 123 are chamfered, and the end side edges of the guide pieces 32, 32 are also chamfered, so that both can be easily drawn in.

In this state, the guide pieces 32, 32 are slightly inserted in the guide grooves 123, 123, and the battery side terminal 120 is positioned with respect to the main body side terminal 30. In this way, the contact pieces 125, 125
Prior to the contact between the and the contact portions 35, 35, 35, the guide pieces 32, 32 and the guide groove 12 made of a mold member.
Since the members 3 and 123 are fitted to each other, it is possible to perform positioning with a member formed with high precision, and therefore, both terminals 12
Before the contact pieces 125 and 125 of 0 and 30 and the contact portion 35 are brought into contact with each other, the positioning of the terminals 120 and 30 is accurately performed, and thereafter the contact pieces 125 and 125 and the contact portion 35 are brought into contact with each other. It can be done accurately.

From this state, the lower part of the battery pack 100 is rotated to mount it on the battery mounting part 10.
The rotation of the battery pack 100 is performed by hooking the locked portion of the rear case 106 of the battery case 101 to the eaves 17 and using this portion as a rotation fulcrum (see FIG. 14).

Then, the contact portion 35 of the main body side terminal 30 relatively penetrates into the terminal arrangement grooves 124, 124, 124 of the battery side terminal 120 (see FIG. 27), and the contact portion 35 has two contact convex portions 125a. , 125a and push it away to bend the contact pieces 125, 125,
The contact portion 35 is sandwiched between them, whereby electrical connection between the battery side terminal 120 and the main body side terminal 30 is achieved (see FIG. 28).

Further, in this case, the contact portion 35 and the contact pieces 125, 125 are relatively moved in the surface direction of the contact portion 35, and the two contact pieces 125, 125 have tip portions (contact convex portions 125a, 125a). ) Is flexible so that it can be expanded, so that an unreasonable force does not act between them, and therefore the contact portion 35 and the contact pieces 125, 125 are not deformed.

Furthermore, such a battery side terminal 120
The main body side terminals 30 are flat plate-shaped contact portions 35, 35, 3 having corner portions that are substantially perpendicular to the terminal arrangement grooves 124, 124, 124 opened in two directions of the battery side terminals 120.
Since it is in contact with 5, the connection direction of both terminals 120, 30 can be within a range of 90 ° including the horizontal direction and the vertical direction.

That is, when viewed from the structure of only the battery side terminal 120 and the main body side terminal 30, the battery side terminal 120 should be connected to the main body side terminal 30 from the left side or the lower side or the diagonally lower left side including them. Can be made, almost 90 °
Of the contact portion 35 and the contact piece 12 in any direction.
No unreasonable force acts on 5, 125, and therefore the contact portion 35 and the contact pieces 125, 125 are not deformed.

Of course, regarding the relationship between the battery pack 100 and the battery mounting portion 10 of the camera body 2,
The battery side terminal 120 is connected to the main body side terminal 30 from the substantially left side, and it may be said that the structures of the battery side terminal 120 and the main body side terminal 30 are not fully utilized.

However, the mounting of the battery pack 100 and the battery mounting portion 10 is rotation, and both terminals 120,
Since the coupling of 30 is not a directional component in at least one direction, by adopting this terminal structure, both terminals 12
It can be said that the contact between the contact portions 35 of 0 and 30 and the contact pieces 125 and 125 is not applied with an unreasonable force, and is not deformed.

Further, contact protrusions 125a and 125a are provided at the tips of the contact pieces 125 and 125, and the contact protrusions 125a and 125a are formed.
Since a and 125a are brought into contact with the contact portion 35, both terminals 12 within the range of 90 ° including the above two directions.
It also allows the binding of 0, 30.

That is, the contact portion 35 is the contact piece 12.
5 and 125 are pushed in and invaded, but the contact portion 35 comes into contact with the contact protrusions 125a and 125a. Therefore, both terminals 120 from any direction within the range of 90 ° including the above two directions. , 30 can be received in the same state, thus facilitating the connection of both terminals 120, 30.

Furthermore, since the contact protrusions 125a and 125a are provided at the tip portions of the contact pieces 125 and 125, the contact pieces 125 and 125
Even if the positions of 125 and the contact portion 35 in the front-rear direction are slightly displaced, a stable connection state of both terminals (contact pieces 125, 125 and the contact portion 35) can be maintained.

Next, regarding the connection of both terminals 120 and 30, the material and thickness of the terminal member 122 that influences the contact state between the contact pieces 125 and 125 and the contact portion 35 will be considered.

The terminal piece 31 is made of brass (thickness: t = 0.
35 mm) and the contact portion is plated with gold of 0.76 μm. The reason why brass is selected as the material of the terminal piece 31 is that brass, phosphor bronze, and beryllium copper are generally used as the contact of the connection terminal, and the cost and workability are taken into consideration.

Regarding gold plating, a nickel layer was used as the underlayer and the thickness was 0.76 μm.
It is considered that 0.3 μm or more is sufficient for the terminal contact, but in consideration of the usage status of the battery pack 100 and the video camera 1, repeated insertion and removal thereof are frequent,
This is because the safety factor is set higher.

As a result, even if it is applied to the terminal structure of the video camera 1 and the battery pack as described above, the contact protrusions 125a and 125a can sufficiently withstand the wear of the gold plating under normal use conditions, and the contact stability can be improved. It is possible to secure the sex.

The 0.76 μm gold plating is mainly the thickness of the contact portion, that is, the contact portion 35.
The lead portion 34 preferably has a gold plating layer thickness of 0.1 μm or less. This is to fuse the solder and the lead portion 34 when soldering, and to secure the electrical connection stability between them.

Then, with respect to the terminal member 122, four samples were tested and selected as one. As the material of the sample, three materials (brass, phosphor bronze, beryllium copper) can be considered as described above.
When considering the spring force of 125, phosphor bronze or beryllium copper is preferable, so tests were performed on these two.

The material of the sample was phosphor bronze (thickness: t = 0.
2mm), 0.76μm gold plating on the contact part, the sample is phosphor bronze (thickness: t = 0.15mm), 0.76μm gold plating on the contact part, the sample is beryllium copper (thickness) : T = 0.2 mm), and the contact portion has a thickness of 0.
76μm gold plating is applied, the sample material is beryllium copper (thickness: t = 0.15mm), 0.76μm in the contact part
Gold plated. As for the gold plating, the nickel layer is used as the underlayer and the layer thickness is 0.76 μm for the same reason as the terminal member 122. Further, the gold plating of 0.76 μm of the terminal member 122 is mainly the contact portion, that is, the layer thickness at the contact protrusions 125 a and 125 a of the contact pieces 125 and 125.
8 is preferably a gold plating layer thickness of 0.1 μm or less.

The test method is the terminal member 122 of the terminal piece 31.
The insertion / extraction test was carried out for 7,000 times.

The test items are contact resistance, total fitting force, total release force and visual inspection.
Each value at a predetermined number of times up to 7,000 times, and the visual inspection is based on visual observation after 7,000 times endurance.

The contact resistance was measured by the four-terminal method, and the open circuit voltage was 20 mV or less, the short circuit current was 100 mA or less, and the standard value was 20 mΩmax.

The total fitting force is obtained by fitting (combining) both terminals 120 and 30 and measuring the fitting force at that time to obtain the fitting force of 10
N (Newton) max.

For the total releasing force, the fitting (coupling) of both terminals 120 and 30 is released, the releasing force at that time is measured, and the releasing force is set to 0.3 N (Newton) min.

The test results for the former three test items are shown in FIGS. 31 to 33.

Regarding the sample, there was little variation in contact resistance and it was stable (see FIG. 31), and the insertion / removal force was also stable, and good values were obtained (see FIG. 32 and FIG. 33). Also,
Also in the visual inspection, the contact protrusions 1 of the contact pieces 125, 125
25a and 125a were worn in appropriate amounts, and no problematic phenomenon was observed.

Regarding the sample, the contact resistance showed a large variation in durability after 7,000 cycles and the total fitting force was weak (see FIG. 32). In addition, in the visual inspection, it was observed that there were few marks of contact scratches, the total fitting force was weak, the contact pressure was poor, and there was a problem in contact resistance.

Regarding the sample, although there was no problem with respect to the contact resistance and the total fitting force, there was a large change in the detaching force at the endurance of 7,000 times, and a so-called "rigid feeling" at the time of detaching was likely to occur. . Also in the visual inspection, the amount of change in the detaching force is large, and thus the number of scratches on the terminal piece 31 is large, and the contact protrusion 12 on the side of the terminal member 122 is accordingly increased.
The wear of 5a and 125a was severe.

For the sample, the total fitting force is small,
Although contact resistance is relatively stable,
It can be said that there is a possibility that a problem will occur in the contact resistance value. In addition, in the visual inspection, the total fitting force was small, and the number of contact scratches was small.

From the above, among the above four samples, it can be considered that the sample is most suitable.

Further, with respect to beryllium copper, when gold plating is applied thereto, only so-called post-plating (plating after processing into a predetermined shape) is possible (difficult), and this is also the reason for selection.

That is, in general, beryllium copper is difficult to form (pressing such as bending) after gold plating, and in the shape of the terminal member 122 as described above, Later shape is the contact protrusion 12
5a and 125a are in contact with each other, and those having such a contact portion will be gold-plated in a state in which the contact portion is in contact when post-plating is performed.

Regarding the above four samples, the above standard values (contact resistance: 20 mΩ max, fitting force: 10 Nma)
x, release force: 0.3 Nmin),
Whichever is selected does not pose a particular problem, but when considering further adverse conditions, it is preferable to select a sample that gives better results.

Further, the contact pressure due to the spring force of the contact pieces 125, 125 when the sample is selected as the material of the terminal member 122 will be considered (see FIGS. 34 to 36).

Before that, the dimensions of the terminal member 122 and the terminal arrangement groove 124 in which the terminal member 122 is arranged will be specified (see FIGS. 34 and 35).

The contact pieces 125, 125 of the terminal member 122 are
As described above, plate thickness t = 0.2 mm, width dimension w = 1.2 m
m, the length of the part exposed from the buried part is l = 3.9 mm
And the contact protrusions 125a and 125a are centered on a position closer to the side of the base piece 127 by 0.45 mm from the tip thereof, and r =
It is formed with a thickness of 0.3 mm (see FIGS. 34 and 35).
Further, the contact pieces 125, 125 extend from the embedded portion so as to approach each other, and are bent so as to be parallel to each other substantially at the center in the lengthwise direction, and the distance between the bent portions and the tip end thereof is large. Is formed to 0.6 mm,
As a result, the contact protrusions 125a and 125
It makes zero contact with a (see FIG. 21).

The opening width of the terminal arrangement groove 124 is 0.45 mm.
And the contact portion 35 has a plate thickness t = 0.35.
Therefore, when the contact portion 35 enters the terminal placement groove 124 at the standard position (middle),
The distance between the inner edge of the terminal placement groove 124 and the contact portion 35 is (0.45-0.35) /2=0.05 mm (see FIGS. 34 and 35).

At this time, the two contact pieces 125, 125 have substantially the same bending, and the displacement amount is 0.175 mm. The contact pressure at that time is 1.0091N. (See Figure 36).

By the way, when the contact portion 35 is biased into one side of the terminal arrangement groove 124 and enters, the one contact piece 125 has the maximum displacement amount and the other contact piece 125 has the minimum displacement amount. Each contact pressure at that time is 1.4
416N and 0.4609N (see FIG. 36).

Therefore, when the material of the above sample (phosphor bronze) is used, the contact pressure at the time of contact with the contact portion 35 is 1.4416 N at the maximum and 0.4 at the minimum.
It was 609 N, and it was found that the contact pressure was sufficient.

In the case of a gold-plated contact, 0.0981N to 0.1961N is generally sufficient as the contact pressure, and in the case of the above sample, a contact pressure higher than that is applied. It seems to be excessive.

However, this terminal structure has the battery pack 1
00 and the video camera 1 are supposed to be applied to electrical contact, the number of times of insertion and removal is large, and it is easily expected that the gold plating will be worn.

Therefore, even if the gold plating is worn out and the nickel layer as the underlayer is exposed, it is necessary to secure the contact resistance value below the standard value.

Therefore, in general, the contact pressure of nickel is 0.
Since it is said that a contact resistance of a specified value can be ensured with about 5884 N, one contact piece 125 has the minimum value of 0.4609 N, but the other contact piece 12 has
By securing the maximum value of 1.4416N in 5,
Even when the gold plating is worn, the contact resistance value satisfies the specified value (see FIG. 36).

In addition, as the inspection item, insulation resistance,
Withstand voltage was measured, but all of the above four samples were within specified values, and no particular difference was observed.

Further, as the environmental resistance performance, the electrical performance and the mechanical performance were inspected in humidity resistance, temperature cycle, salt water spray, etc., but no particular difference was obtained.

Next, in the above-mentioned embodiment, the battery pack 100 is taken as an example having the battery side terminal 120 (mounting part) and the video camera 1 is taken as an example having the main body side terminal 30 (main body side device). As described above, the battery pack 100 and the dry battery pack 140 are examples of the one having the battery side terminal 120 (mounting part), and the video camera is one of the one having the main body side terminal 30 (the main body side device). 1, there is a video light 150, a charger 160, and the like (see FIGS. 37 to 40).

Further, there are a plurality of types of battery packs 100 due to differences in their capacities, and as for the video camera 1, there are a charging-compatible type 1A having a charging function and a charging-unsupporting type 1B having no charging function. (See FIGS. 37 to 40).

All devices having such a battery side terminal 120 (a plurality of types of battery packs 100, dry battery packs 140, etc.) have a device having the main body side terminal 30 (video camera 1 (chargeable type 1A, non-chargeable type). 1B), video light 150, charger 160, etc.)
If it can be attached to, there may be a problem.

For example, the dry battery pack 140 can be attached to the video camera 1B (non-charging type), but it must be "impossible" not to be attached to the video camera 1A (charging type) or the charger 160. For the high-capacity dedicated type 150A of the video light 150, only the high-capacity battery pack 100H of the battery pack 100 is set as "OK", and other low-capacity battery packs 100L and standard-capacity battery packs 100S and The attachment of the dry battery pack 140 needs to be “disabled”.

Here, the charging-compatible type 1A of the video camera 1 means that the camera body 2 has a DCin terminal,
When the DC in jack is connected to the in terminal, the camera body 2 can be driven while charging the battery pack 100 mounted in the battery mounting portion 10. The unsupported type 1B of the video camera 1 is such charging. It has no function. By the way, the video camera 1 exemplified in the above-mentioned embodiment is of a charging type 1A,
The battery pack 140 is of a type that cannot be mounted.

Then, such a battery side terminal 120
It is necessary to determine whether or not the device is equipped with the device having the main body side terminal 30, but to prevent the device from being installed when the device is not installed.

Therefore, the discriminator 111 is provided near the battery side terminal 120, and the blocking portion 19 for blocking the mounting of the battery pack 100 or the like is provided at a corresponding portion near the body side terminal 30.

Hereinafter, the discriminator 1 of the battery side terminal 120 will be described.
11 and a specific example of the blocking portion 19 of the main body side terminal 30 are shown.

The types of the discriminator 111 of the battery side terminal 120 are, for example, L type, S type, H type and D type.
There are four types, the L type discriminator 111L is a low capacity type battery pack 100L, and the S type discriminator 111S is a standard capacity type battery pack 100S.
In addition, the H type discriminator 111H is applied to the high capacity type battery pack 100H, and the D type discriminator 111D is applied to the dry battery pack 140 (FIGS. 37 to 40).
reference).

The blocking portion 19 of the main body side terminal 30 has four types of type I, type II, type III and type IV.
There are different types, the blocking unit type I is a charging compatible type video camera 1A (same for the charger 160)
II is a non-chargeable type video camera 1B, blocking unit type III is a high capacity dedicated video light 150A,
The blocking unit type IV is applied to the low-capacity video light 150B (see FIGS. 37 to 40).

The S type discriminator 111S applied to the standard capacity battery pack 100S has the structure as described above, and the terminal positioning rib 109 is formed to a position slightly to the right of the back surface 106a of the back case 106. Small protrusions 110 are formed so as to extend in the opposite directions (front-rear direction) from the left end of (see FIGS. 37 to 40).

The L type discriminator 111L applied to the low capacity battery pack 100L is the S type discriminator 11 described above.
The small protrusion 110 formed at the left end of the terminal positioning rib 109 of 1S extends to the back surface 106a of the back case 106,
Therefore, the small protrusion 110L of the L type discriminator 111L is continuously formed on the back surface 106a of the back case 106 (see FIGS. 37 to 40).

The H type discriminator 111H applied to the high capacity battery pack 100H is the same as the S type discriminator 11 described above.
Small protrusions 110 and 110L extending in mutually opposite directions (front-back direction) such as 1S and L type discriminator 111L are not formed (see FIGS. 37 to 40).

The D-type discriminator 111D applied to the dry battery pack 140 is similar to the H-type discriminator 111H in that the small protrusion 11 extends from the left end of the terminal positioning rib 109.
0 and 110L are not formed, but the front case 105
A discriminating rib 141 extending rightward from the central portion of the terminal pressing rib 116 formed with is formed integrally (see FIGS. 37 to 40).

Next, the structure of each blocking unit 19 will be described, and the combination with each discriminator 111 will also be described.

First, the blocking portion type I of the main body side terminal 30
Is applied to the video camera 1 (charging type 1A) according to the above-mentioned embodiment, and the battery mounting unit 1
0 of the upper frame 13 and an eaves portion 17 and the blocking ridge 18 formed to extend leftward from the rear end of the eaves portion 17 (see FIG. 37).

In such a blocking portion type I, the central portion of the eaves portion 17 is the discrimination rib 1 of the D type discriminator 111D.
Since it interferes with 41, its mounting is set to “impossible”, and there is no part that interferes with other types of discriminators 111, and its mounting is set to “permitted”.

Therefore, the dry battery pack 140 cannot be attached to the charging compatible type video camera 1A to which the blocking unit type I is applied, and therefore an accident such as accidentally charging the dry battery pack 140 may occur. Can be prevented. On the other hand, other types of discriminators 111L, 1
Battery pack 100 to which 11S and 111H are applied
L, 100S, and 100H can be mounted on the battery mounting portion 10 regardless of their capacity (see FIG. 3).
7).

In the blocking portion type II, the notch 17a is formed in the central portion of the eaves portion 17, and this does not interfere with the discrimination rib 141 of the D type discriminator 111D, so that it can be mounted. In addition, there is no portion that interferes with the discriminators 111L, 111S, 111H of other types, and eventually the discriminators 111L, 111 of all types are
The mounting of S and 111H is set to “OK” (see FIG. 38).

Therefore, all of the low capacity battery pack 100L, the standard capacity battery pack 100S, the high capacity battery pack 100H and the dry battery pack 140 are mounted on the non-charge compatible type video camera 1B to which the blocking unit type II is applied. (See FIG. 38).

In the blocking portion type III, the end of the blocking ridge 18 formed from the rear end of the eaves portion 17 toward the bottom surface 15 (left side) reaches the bottom surface 15 of the battery mounting portion 10. In addition, the blocking ridge 18 is also provided in front of the blocking ridge 18.
Are integrally formed from the bottom surface 15. The distance between the two blocking protrusions 18 is two terminal positioning ribs 1 provided so as to sandwich the battery side terminal 120 from the front and rear.
They are formed to have almost the same distance between 09 and 109 (see FIG. 39).

In such a blocking portion type III,
Since the central portion of the eaves portion 17 interferes with the discrimination rib 141 of the D type discriminator 111D, its mounting is “impossible”, and
L type discriminator 111L and S type discriminator 111S
Since the small protrusions 110 and 110L extending from the left ends of these terminal positioning ribs 109 in the opposite directions (front-rear direction) interfere with the blocking protrusions 18 and 18, their mounting is also “impossible”. The H-type discriminator 111H does not have a portion that interferes with the blocking portion type III, so that the mounting is “OK” (see FIG. 39).

Therefore, the high capacity dedicated video light 150A to which the blocking unit type III is applied has a low capacity battery pack 100L and a standard capacity battery pack 100.
S and dry battery pack 140 cannot be installed,
Only the high capacity battery pack 100H can be attached to the high capacity dedicated video light 150A (see FIG. 39).

In the blocking portion type IV, similarly to the blocking portion type I, the blocking ridge 18 formed from the rear end of the eaves portion 17 toward the bottom surface 15 (left side) is the battery mounting portion 10.
Although it does not reach the bottom surface 15 of the battery, a small projection 18a is formed on a portion of the extension that is in contact with the bottom surface 15 of the battery mounting portion 10. The small projection 18a is formed in front of the small projection 18a.
a is integrally formed from the bottom surface 15. And 2
The interval between the two small protrusions 18a, 18a is formed to be substantially the same as the interval between the two terminal positioning ribs 109, 109 provided so as to sandwich the battery side terminal 120 from the front and rear (see FIG. 40).

In the blocking portion type IV, the central portion of the eaves portion 17 is the discrimination rib 1 of the D type discriminator 111D.
Because it interferes with 41, its mounting is “impossible”, and L
The type discriminator 111L has a terminal positioning rib 109,
The small protrusions 110L and 110L extending from the left end of 109 in opposite directions (front-rear direction) are the small protrusions 18a and 18a.
Since it interferes with the installation, it is not possible to install it. And S
The type discriminator 111S has a terminal positioning rib 109,
Since the small protrusions 110, 110 extending from the left end of 109 in opposite directions (front-rear direction) are formed at positions slightly separated from the bottom surface 106a of the battery pack 100S,
Since there is no part that interferes with the blocking type IV, its mounting is “OK”. Further, the H type discriminator 111H does not have a portion that interferes with the blocking portion type IV, and therefore, the mounting is also “permissible” (see FIG. 40).

Therefore, the low capacity non-capable video light 150B to which the blocking unit type IV is applied is not equipped with the low capacity battery pack 100L and the dry battery pack 140, but the standard capacity battery pack 100S and the high capacity battery pack. 100H can be attached (see FIG. 40).

Although not shown, the blocking unit type IV
A detection switch is provided near the small protrusion 18a of
The presence or absence of the small protrusion 110 of the type discriminator 111S is detected,
It is determined whether the S type discriminator 111S or the L type discriminator 111L.

Then, the above-mentioned low capacity impossible video light 15
OB is equipped with two light bulbs and has a high capacity battery pack 1
Two bulbs are lit when 00H is mounted, and one bulb is lit when the standard capacity battery pack 100S is mounted.

As described above, by providing the discriminator 111 and the blocking portion 19 near the battery side terminal 120 and the main body side terminal 30, respectively, the battery side terminal 120 and the main body side terminal 30 can be mounted before they are connected. Whether or not it is possible to judge whether it is possible or not
It is possible to avoid the combination of 20, 30. That is,
Even if it is installed by mistake, both terminals 120, 30
Since the discriminator and the blocking unit are provided in the vicinity of the
The connection of 20, 30 is released, and therefore the terminal member 122
It is possible to avoid contact between the terminal piece 31 and the terminal piece 31.

It should be noted that the discriminator 111 and the blocking unit 19 are provided.
The shape and the forming position thereof are merely examples, and the present invention is not limited to this, and the discriminator 111 and the blocking portion 19 may be provided in the vicinity of the battery side terminal 120 and the main body side terminal 30, and these are applied. The battery pack 100, the dry battery pack 140 and the video camera 1 (1
A, 1B), the video light 150, the charger 160, and the like, and various types are conceivable.

Next, another embodiment of the battery pack of the present invention will be shown and an assembling method thereof will be described.

FIG. 45 shows a battery pack 1 in which one battery cell 102 is housed in a battery case 101A.
00A, which is of a type different from that mounted on the video camera 1.

The method of assembling the battery pack 100A will be described below in the order of FIGS. 41 to 45.

First, the battery side terminal 120 is mounted on the substrate 104A having a predetermined size. The battery side terminal 120 is the same as that used in the battery pack 100.

In such a mount, the terminal case 121 of the battery side terminal 120 is provided with two positioning projections (not shown), and the projections are small holes (not shown) formed in the substrate 104A. .) Respectively.

The lead pieces 128, 128, 128 of the battery side terminal 120 positioned on the board 104A are the board 1
04A is placed on a predetermined wiring pattern and these are soldered to each other, whereby the battery side terminal 120 and the substrate 1
04A is electrically connected (see FIG. 41).

Next, such a board 104A is soldered to the terminal portions (plus terminal 102a and minus terminal 102b) of the battery cell 102, and the board 104 is attached to the battery cell 102. At this time, the positive terminal 102a and the negative terminal 102b of the battery cell 102 are connected to the substrate 104.
After penetrating the land holes 104a, 104a formed in the above, respectively, soldering is performed.

The positive terminal 102a of the battery cell 102
Is projected from the side surface (board-side end surface) of the battery cell 102 to which the board 104 is attached, while the negative terminal 102b is projected from the end surface opposite to the board-side end surface and the side surface of the battery cell 102 is covered with an insulating sheet. It is formed at the tip of the terminal plate 102c extending to the end face on the substrate side so as to crawl through (see FIG. 42).

The battery cell 102 to which such a substrate 104A is attached is housed in the rear case 106A. At this time, the slide protrusion 129 of the battery side terminal 120,
129 is a slide groove 117A of the rear case 106A, 1
By inserting and sliding the battery-side terminal 120 in the rear case 106A into the rectangular cutout 10A of the rear case 106A.
8A (see FIG. 43). The shape of the rectangular cutout 108A is the same as that of the rectangular cutout 108 shown in the above-mentioned embodiment, and therefore the details thereof will be omitted.

As a result, the battery side terminal 120 is positioned with respect to the rear case 106A in the width direction and the length direction. At this time, the end surface of the battery-side terminal 120 is flush with the opening edge of the rear case 106A (see FIG. 44).

Finally, the front case 105A is aligned with the rear case 106A so as to cover the battery cells 102, and both are joined (see FIGS. 44 and 45).

At this time, the projection 11 of the front case 105A
8, 118 are cut grooves 130, 13 of the rear case 106A.
0, the terminal pressing rib 116 presses the terminal case 121, and the exposed base pieces 127, 127, 127 of the terminal member 122 are covered. Then, the battery side terminal 120 is positioned in the thickness direction of the battery pack 100A such that it is sandwiched between the rear case 106A and the front case 105A.

The front case 105A and the rear case 1
The connection with 06A is in the state that both opening edges are aligned,
It is performed by ultrasonic welding. It should be noted that the adhesion is not limited to ultrasonic welding and may be adhesion using an adhesive.

As described above, the battery pack 100A is
The three parts of the rear case 106A, the battery cell 102 (including the battery-side terminal 120, the board 104A, etc.) and the front case 105A can be configured only by assembling from one direction, so that a complicated movement for assembling. Therefore, it is easy to automate the assembly process.

Next, the assembly of the same battery pack 100A by a different assembly method will be described (see FIGS. 41, 46, 47, 44 and 45).
