EMBODIMENT OF THE INVENTION Below, embodiment of the terminal block which concerns on this invention is described in detail based on drawing. In addition, this invention is not limited by this embodiment.

[Embodiment]
One embodiment of a terminal block according to the present invention will be described with reference to FIGS. 1 to 8. FIG.

Reference numeral 1 in FIGS. 1 to 8 indicates the terminal block of this embodiment. The terminal block 1 includes a relief terminal 10 directly or indirectly electrically connected to an electrode terminal 501 of a battery 500, and a cover 20 that covers and protects the relief terminal 10. It is used when power is supplied from a vehicle, a portable battery, or the like (Figs. 3 to 8).

The electrode terminal 501 shown here is a truncated cone-shaped positive or negative battery post vertically provided on the upper surface of the battery 500 . The electrode terminal 501 projects vertically upward from the upper surface of the battery 500 in a vehicle-mounted state. The relief terminal 10 is electrically connected directly or indirectly to the positive electrode terminal 501 .

The relief terminal 10 has a first electrical connection portion 11 that is directly or indirectly electrically connected to the electrode terminal 501 (FIGS. 3 to 8). The first electrical connection portion 11 shown here is indirectly electrically connected to the electrode terminal 501 . Therefore, the terminal block 1 is directly or indirectly electrically connected to the electrode terminal 501, and the first electrical connection portion 11 is directly or indirectly electrically connected to the electrode terminal 501. A terminal fitting 30 for indirectly electrically connecting the first electrical connection portion 11 is provided (FIGS. 1 and 3 to 8).

For example, the terminal block 1 is installed on the upper surface of the battery 500 housed in the engine compartment of the vehicle. In this case, the terminal fitting 30 is a battery terminal that is directly electrically connected to the positive electrode terminal 501 on the upper surface of the battery 500 and is physically and electrically connected to the electrode terminal 501 . Moreover, the terminal block 1 is installed at a location away from the battery 500 in the vehicle, for example, when the battery 500 is accommodated in the trim of the luggage compartment. In this case, the terminal fitting 30 is fixed, for example, to an electrical insulating portion in the engine compartment, and indirectly electrically connected to the electrode terminal 501 via an electric wire or the like. Here, the terminal block 1 installed on the upper surface of the battery 500 is taken as a specific example.

The terminal fitting 30 is molded using a metal plate as a base material. The terminal fitting 30 includes a first terminal connection portion 31 that is directly electrically connected to the electrode terminal 501, and a first terminal connection portion 31 that is adjacent to the first terminal connection portion 31 so that the first electrical connection portion 11 is directly or indirectly connected to the electrode terminal 501. and a second terminal connection portion 32 for electrical connection (FIGS. 3, 6 and 7).

The electrode terminal 501 is inserted into the first terminal connection portion 31, and the first female screw member 36 screwed into the first male screw member 35 is tightened to crimp the electrode terminal 501, whereby the electrode terminal is crimped. 501 (FIGS. 1, 4, 7 and 8). The second terminal connection portion 32 is assembled with the second male screw member 41 with the screw axis direction aligned with the direction perpendicular to the plane, and is electrically connected to the first electrical connection portion 11 directly or indirectly. It is formed in a flat plate shape (FIGS. 3, 6 and 7). The plane of the second terminal connecting portion 32 is perpendicular to the vertical direction when the terminal fitting 30 is assembled to the electrode terminal 501 . The second male screw member 41 assembled to the second terminal connection portion 32 has a screw axis parallel to the central axis of the electrode terminal 501 in a state where the terminal fitting 30 is assembled to the electrode terminal 501. In addition, it protrudes vertically upward from the second terminal connection portion 32 .

The first electrical connection portion 11 is fastened together to the second terminal connection portion 32 using a second male screw member 41 and a second female screw member 42 (FIGS. 3 to 8). Therefore, the first electrical connection portion 11 is formed in a flat plate shape to be directly or indirectly electrically connected to the second terminal connection portion 32 by fastening together. A through hole 11a through which the second male thread member 41 is inserted is formed in the first electrical connection portion 11 (FIG. 7). The first electrical connection portion 11 has the second male screw member 41 inserted through the through hole 11a, and is laminated on the second terminal connection portion 32, for example, by aligning the planes thereof. In the relief terminal 10 and the terminal fitting 30, the first electrical connection portion 11 and the second terminal connection portion 32 are tightened together by tightening the second female screw member 42 into the second male screw member 41 from vertically above. fixed and both are electrically connected (FIGS. 3, 6 and 7).

However, in this example, a plate-shaped electrical connection portion 601a of a busbar 601 of a circuit protection component (fuse, fusible link, etc.) 600 is interposed between the first electrical connection portion 11 and the second terminal connection portion 32. (Figs. 3, 6 and 7). That is, in this example, the electrical connection portion 601a is laminated on the second terminal connection portion 32 with the planes thereof aligned, and the first electrical connection portion 11 is laminated on the electrical connection portion 601a with the planes thereof aligned. In this example, the first electrical connection portion 11, the second terminal connection portion 32, and the electrical connection portion 601a are fastened together by the second male screw member 41 and the second female screw member 42, thereby electrically connecting them. connect. The circuit protection component 600 exposes its electrical connection portion 601a. By stacking this electrical connection portion 601a on the second terminal connection portion 32, the circuit protection component 600 is arranged on the side of the battery 500 (see FIG. 1). Figure 6).

The rescue terminal 10 is housed in the housing position (FIGS. 1 to 3) during normal times when rescue from a rescue vehicle, a portable battery, etc. is not required, and is sandwiched by a clip 701 (FIG. 8) of the booster cable 700 and attached to the clip 701. It has a second electrical connection portion 12 (FIGS. 3 to 8) that is displaced from the housed position to a rescue position above the vehicle (FIGS. 4 to 6 and 8) at the time of rescue for electrical connection. The rescue terminal 10 has a rotating portion 13 for rotating the second electrical connection portion 12 with respect to the first electrical connection portion 11 between the accommodation position and the rescue position (FIGS. 3 to 8).

The relief terminal 10 shown here is a press-formed product formed using a metal plate as a base material, and the first electrical connection portion 11, the second electrical connection portion 12, and the rotating portion 13 are integrally formed. be. Here, the first electrical connection portion 11 and the second electrical connection portion 12 are formed in a rectangular flat plate shape, and the ends of the first electrical connection portion 11 and the second electrical connection portion 12 are connected by the rotating portion 13 . They are connected (Figures 3 to 8).

The relief terminal 10 has a bent shape bent toward the first electrical connection portion 11 side and the second electrical connection portion 12 side using the rotating portion 13 as a bending point, and the first electrical connection portion in the bent shape. The placement of the second electrical connection 12 relative to 11 is shaped to be in the rescue position (Figs. 4-8). That is, the relief terminal 10 includes a first electrical connection portion 11 extending in a first direction, a second electrical connection portion 12 extending in a second direction intersecting the first direction, and a first electrical connection portion 11 extending in a second direction. and a rotating portion 13 connecting the first electrical connection portion 11 and the second electrical connection portion 12 at a position where the connection portion 11 and the second electrical connection portion 12 intersect. In this rescue terminal 10, in order to facilitate the work of connecting the clip 701 at the rescue position, the first electrical connection portion 11 and the second electrical connection are arranged such that the first direction and the second direction form a right angle or an obtuse angle. Positioning the portion 12 is desirable.

Here, the first electrical connection 11 and the second electrical connection 12 form an obtuse angle. The rescue terminal 10 allows the second electrical connection portion 12 to be arranged vertically above the first electrical connection portion 11 when the second electrical connection portion 12 is in the accommodated position (FIG. 3). In the relief terminal 10 shown here, when the second electrical connection portion 12 is in the accommodated position, the planes of the first electrical connection portion 11 and the second electrical connection portion 12 are perpendicular to the vertical direction, and the The first electrical connection portion 11 and the second electrical connection portion 12 are arranged to face each other with a space therebetween in the vertical direction.

In the relief terminal 10 in which the first electrical connection portion 11 and the second electrical connection portion 12 form an obtuse angle, the rotating portion 13 moves the second electrical connection portion 12 to the relief position with respect to the first electrical connection portion 11 within the elastic region. It is formed as an elastically deformable portion that can be rotated from the housing position to the housing position. In this rescue terminal 10, by applying an external force to the second electrical connection portion 12 (FIGS. 4 to 6) at the rescue position toward the housed position, the rotating portion 13 is elastically deformed while being moved to the rescue position. The second electrical connection portion 12 is rotated to the accommodation position with respect to the first electrical connection portion 11 (FIG. 3). In the relief terminal 10 , when the application of the external force is stopped, the elastic force accompanying the elastic deformation of the rotating portion 13 causes the second electrical connection portion 12 in the accommodation position to move relative to the first electrical connection portion 11 . It returns to the rescue position while rotating (Figs. 4 to 6).

In order to avoid the circuit protection component 600, the rotating portion 13 shown here is provided between the first electrical connection portion 11 and the second electrical connection portion 12 when the second electrical connection portion 12 is in the accommodation position. It has a crank shape (Fig. 3).

The cover 20 is molded from an insulating material such as synthetic resin. The cover 20 has a base portion 21, an opening/closing portion 22, and a hinge portion 23 for rotating the opening/closing portion 22 with respect to the base portion 21 between a closed position and an open position (FIGS. 1 to 3, FIG. 6 and Figure 7).

The base portion 21 is a portion forming the basic skeleton of the cover 20 and also serves as a fixing portion for fixing the cover 20 to the vehicle side. For example, this base 21 is fixed to the battery 500 side. The base portion 21 shown here also functions as a protection portion that covers and protects the circuit protection component 600 from above (FIGS. 2 and 3). Therefore, the base portion 21 is fitted and fixed to the circuit protection component 600 from the outside.

Here, the cover 20 has a holding mechanism (hereinafter referred to as “first holding mechanism”) 24 that holds the base 21 to the circuit protection component 600 . The first holding mechanism 24 includes a claw-shaped first locking portion 24a protruding from the inner wall of the base portion 21, and a claw-like first locking portion 24a protruding from the outer wall of the circuit protection component 600. and a claw-shaped second locking portion 24b arranged at a position capable of locking the first locking portion 24a at the assembly completion position (FIG. 3). This first holding mechanism 24 is provided at a plurality of locations.

The opening/closing part 22 is rotatable between the housed position and the rescue position together with the second electrical connection part 12 in contact with the inner wall, and covers the second electrical connection part 12 in the housed position at the closed position. It is accommodated in the cover (FIG. 3), and in the open position, the second electrical connection portion 12 in the rescue position is exposed and clipped together with the second electrical connection portion 12 by the clip 701 (FIGS. 4 to 6 and 8). ).

The opening/closing portion 22 has a main wall portion 22a formed in a flat plate shape. are rotated together between the stowed position and the rescue position (Figs. 1 to 6). When the opening/closing portion 22 is in the closed position, the main wall portion 22a of the opening/closing portion 22 vertically covers the second electrical connection portion 12 in the housed position (FIG. 3). When the opening/closing portion 22 is in the open position, a clip 701 is inserted from one end of the main wall portion 22a, and the clip 701 clamps the main wall portion 22a and the second electrical connection portion 12 (see FIG. 4). 6 and 8). For this reason, in the opening/closing portion 22, there is no insert obstruction factor such as a protrusion on the insertion trajectory of the clip 701 from one end of the main wall portion 22a. Here, the end portion of the main wall portion 22a opposite to the hinge portion 23 serves as the insertion starting point _22a1 of the clip 701 (FIGS. 3 to 8).

Here, in the illustrated rescue terminal 10, the first electrical connection portion 11 and the second electrical connection portion 12 face each other in the housed position. Therefore, in the cover 20 , the cover body itself that covers the relief terminal 10 in the closed position is used as the opening/closing portion 22 . For this reason, the opening/closing part 22 has the side walls 22b and 22c vertically provided from the main wall 22a except for _one end of the clip 701 insertion starting point 22a1. covers and protects the relief terminal 10 with . (FIGS. 1, 2, 4 and 5) The two side walls 22b and 22c are arranged to face each other with a space therebetween.

Furthermore, the opening/closing part 22 may cover the terminal fitting 30 together with the relief terminal 10 in the closed position. Furthermore, the opening/closing part 22 may cover the positive electrode terminal 501 together with the relief terminal 10 and the terminal fitting 30 in the closed position. The opening/closing part 22 (cover main body) shown here is formed to cover the relief terminal 10, the terminal metal fitting 30, and the electrode terminal 501 in the closed position (FIG. 3).

In the cover 20, when the second electrical connection portion 12 is in the accommodated position, the first electrical connection portion 11 and the second electrical connection portion 12 extend in opposite directions from the rotating portion 13. (for example, when the first electrical connection portion 11, the second electrical connection portion 12, and the rotating portion 13 are in the shape of a crank), the cover main body covering the first electrical connection portion 11 and the An opening/closing part 22 may be provided (not shown).

The hinge portion 23 shown here is formed as a so-called living hinge that rotatably connects the base portion 21 and the opening/closing portion 22 . The hinge portion 23 is provided adjacent to the rotating portion 13 of the rescue terminal 10 , and as the second electrical connecting portion 12 and the opening/closing portion 22 rotate, the second electrical connecting portion 12 moves toward the main wall portion of the opening/closing portion 22 . It is desirable to form it so that it does not leave the inner wall of 22a (FIGS. 3-6 and 8). In order to avoid an overload between the second electrical connection portion 12 and the cover 20, the clip 701 is inserted along the inner wall of the main wall portion 22a while the second electrical connection portion 12 is kept in contact with the inner wall of the main wall portion 22a as it rotates. It is desirable to be able to slide between one end which is the starting point _22a1 and the other end on the hinge portion 23 side. Therefore, the opening/closing portion 22 may be provided with a guide portion (not shown) for sliding the second electrical connection portion 12 as it rotates. The guide portion is, for example, claw portions at the tips of a plurality of projections projecting from the inner wall of the main wall portion 22a. The projections are arranged to face each other in a direction orthogonal to the sliding direction of the second electrical connection portion 12 .

The cover 20 has a holding mechanism (hereinafter referred to as a "second holding mechanism") 25 for holding the opening/closing portion 22 in the closed position (FIGS. 4 and 7). The second holding mechanism 25 may hold the opening/closing portion 22 in the closed position with respect to the base portion 21, or may hold the opening/closing portion 22 in the closed position with respect to peripheral components. good. Here, the circuit protection component 600 holds the opening/closing portion 22 in the closed position. The second holding mechanism 25 is provided in the claw-shaped first locking portions 25a (FIGS. 4 and 7) protruding from the inner walls of the side walls 22b and 22c of the opening/closing portion 22 and the circuit protection component 600 to open and close. and a second locking portion 25b (FIG. 7) that hooks onto the first locking portion 25a when the portion 22 is in the closed position and holds the opening/closing portion 22 in the closed position. In the opening/closing portion 22, each side wall portion 22b, 22c is made flexible. Therefore, in the opening/closing portion 22, the first locking portion 25a and the second locking portion 25b can be arranged in a mutually locking state when the opening/closing portion 22 is rotated from the open position to the closed position. Moreover, when rotating from the closed position to the open position, the lockable state of the first locking portion 25a and the second locking portion 25b can be released.

In the rescue terminal 10, the elastic force toward the rescue position due to the elastic deformation of the rotating portion 13 causes the second electrical connection portion 12 at the accommodation position to apply force to the inner wall of the main wall portion 22a of the opening/closing portion 22. there is Therefore, when the opening/closing portion 22 is in the closed position, the side walls 22b and 22c are bent to release the lockable state of the first locking portion 25a and the second locking portion 25b. , receives force from the second electrical connection portion 12, and is displaced to the open position while rotating together with the second electrical connection portion 12. As shown in FIG. Accordingly, the second electrical connection portion 12 and the opening/closing portion 22 are arranged above the terminal metal fitting 30 and the electrode terminal 501 in the vehicle. That is, in this terminal block 1, by opening the opening/closing portion 22 to the open position, the second electrical connection portion 12 protrudes above the vehicle from the opening/closing portion 22 at the closed position.

Usually, other parts are not arranged above the opening/closing part 22 in the closed position because they interfere with rescue work. However, in this example, the hood of the vehicle is located above the opening/closing portion 22 in the closed position, but since the bonnet can be opened at the time of rescue, there are other parts above the opening/closing portion 22 in the closed position. never exist. Therefore, at the time of rescue, by opening the opening/closing part 22 from the closed position to the open position, the second electrical connection part is located above the terminal fitting 30 and the electrode terminal 501 in the vehicle and in a place where other parts do not exist. 12 and the opening/closing part 22 are protruded. Therefore, this terminal block 1 can secure a large connection space for the clip 701 at the time of rescue, and facilitates the connection work of the clip 701 . Furthermore, since the terminal block 1 does not need to connect the clip 701 to the electrode terminal 501 at the time of rescue, there is no need to provide a connection space for the clip 701 around the electrode terminal 501 . Therefore, this terminal block 1 contributes to making the periphery of the electrode terminal 501 compact.

By the way, the relief terminal 10 has a bent shape that is bent toward the first electrical connection portion 11 side and the second electrical connection portion 12 side using the rotating portion 13 as a bending point, and the first electrical connection is made in the bent shape. The arrangement of the second electrical connection portion 12 with respect to the portion 11 may be molded so as to be in the accommodation position. In this case, the rotating portion 13 is formed as an elastically deformable portion that can rotate the second electrical connecting portion 12 with respect to the first electrical connecting portion 11 from the accommodation position to the rescue position within the elastic range. In this rescue terminal 10, by applying an external force to the second electrical connection portion 12 at the housed position toward the rescue position, the rotating portion 13 is elastically deformed, and the second electrical connection portion 12 is moved from the housed position. It is rotated to the rescue position with respect to the first electrical connection portion 11 . In the rescue terminal 10 , when the application of the external force is stopped, the elastic force accompanying the elastic deformation of the rotating portion 13 causes the second electrical connection portion 12 at the rescue position to move toward the first electrical connection portion 11 . It returns to the stowed position while rotating.

When using such a relief terminal 10 , it is necessary to hold the second electrical connection portion 12 on the inner wall of the opening/closing portion 22 in the cover 20 . For this reason, the opening/closing portion 22 is provided with a holding portion (not shown) for holding the second electrical connection portion 12 in contact with its inner wall. The holding portion is, for example, a claw portion at the tip of a plurality of protrusions protruding from the inner wall of the opening/closing portion 22, and the second electrical connection portion 12 is hooked on these claw portions to hold the second electrical connection portion 12. It is held on the inner wall of the opening/closing part 22 .

Furthermore, in this case, it is necessary to prevent the second electrical connection portion 12 at the rescue position from returning to the accommodation position due to elastic force during rescue. For this reason, the cover 20 is provided with a holding mechanism (hereinafter referred to as a "third holding mechanism") for holding the opening/closing portion 22 in the open position (not shown). This third holding mechanism holds the opening/closing part 22 at the open position with respect to the base part 21, for example. The third holding mechanism includes a claw-shaped first engaging portion protruding from the opening/closing portion 22, and provided on the base portion 21. When the opening/closing portion 22 is in the open position, the first engaging portion is hooked to hold the opening/closing mechanism. and a second locking portion that holds the portion 22 in the open position.

Even in this case, the terminal block 1 can obtain the same effect as the previous example.
