Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, a connection space for connecting a clip is required around the electrode terminal. Therefore, in order to secure this connection space, peripheral components must be separated from the electrode terminal. However, it is difficult to secure a wide connection space depending on the component configuration of the vehicle.

[0005] Therefore, an object of the present invention is to provide a terminal block that facilitates the connection operation of the clip.

Means for Solving the Problems

[0006] The present invention comprises a rescue terminal directly or indirectly electrically connected to the electrode terminals of a battery, and a cover covering the rescue terminal, wherein the rescue terminal includes a first electrical connection portion that directly or indirectly electrically connects to the electrode terminals, a second electrical connection portion that is housed in a storage position when rescue is not needed and is clamped by a booster cable clip to electrically connect to the clip, and the second electrical connection portion is positioned relative to the first electrical connection portion between the storage position and the rescue position The cover has a base and a rotating part that rotates between the housing position and the rescue position together with the second electrical connection part which is in contact with the inner wall, and an opening / closing part that covers the second electrical connection part in the housing position and houses it inside the cover in the closed position, and exposes the second electrical connection part in the rescue position and clamps it together with the second electrical connection part in the clip in the open position, and a hinge part that rotates the opening / closing part between the closed position and the open position relative to the base. [Effects of the Invention]

[0007] In the terminal block according to the present invention, opening the switch to the open position causes the second electrical connection to protrude above the vehicle above the switch in the closed position. Normally, no other components are placed above the vehicle above the switch in the closed position because they would interfere with rescue operations. Therefore, during rescue operations, opening the switch from the closed position to the open position causes the second electrical connection and the switch to protrude above the electrode terminals and into a location where no other components are present. Consequently, this terminal block allows for a wider connection space for clips during rescue operations, making the clip connection work easier. [Brief explanation of the drawing]

[0009] An embodiment of the terminal block according to the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention.

[0010] [Embodiment] One embodiment of the terminal block according to the present invention will be described with reference to Figures 1 to 8.

[0011] Reference numeral 1 in Figures 1 to 8 indicates the terminal block of this embodiment. This terminal block 1 comprises a rescue terminal 10 that is directly or indirectly electrically connected to the electrode terminal 501 of the battery 500, and a cover 20 that covers and protects the rescue terminal 10, and is used when supplying power from a rescue vehicle or portable battery (Figures 3 to 8).

[0012] The electrode terminal 501 shown here refers to a frustoconical positive or negative battery post mounted vertically on the upper surface of the battery 500. This electrode terminal 501 protrudes vertically upward from the upper surface of the battery 500 when it is installed in the vehicle. The rescue terminal 10 is electrically connected directly or indirectly to the positive electrode terminal 501.

[0013] The rescue terminal 10 has a first electrical connection part 11 that is electrically connected directly or indirectly to the electrode terminal 501 (Figures 3 to 8). The first electrical connection part 11 shown here is electrically connected indirectly to the electrode terminal 501. Therefore, the terminal block 1 is equipped with terminal fittings 30 that are electrically connected directly or indirectly to the electrode terminal 501, and that also electrically connect the first electrical connection part 11 directly or indirectly, thereby indirectly electrically connecting the first electrical connection part 11 to the electrode terminal 501 (Figures 1 and 3 to 8).

[0014] For example, terminal block 1 is installed on the top surface of a battery 500 housed in the engine compartment of a vehicle. In this case, terminal fitting 30 is a battery terminal that is directly electrically connected to the positive electrode terminal 501 on the top surface of the battery 500, and is physically and electrically connected to the electrode terminal 501. Alternatively, if the battery 500 is housed in the trim of the cargo compartment, terminal block 1 may be installed in a location away from the battery 500 within the vehicle. In this case, terminal fitting 30 may be fixed to an electrically insulated part in the engine compartment, for example, and indirectly electrically connected to the electrode terminal 501 via wires or the like. Here, terminal block 1 installed on the top surface of a battery 500 is given as a specific example.

[0015] The terminal fitting 30 is formed using a metal plate as the base material. This terminal fitting 30 has a first terminal connection portion 31 that directly connects to the electrode terminal 501, and a second terminal connection portion 32 adjacent to the first terminal connection portion 31 that directly or indirectly connects to the first electrical connection portion 11 (Figures 3, 6, and 7).

[0016] The first terminal connection portion 31 physically and electrically connects to the electrode terminal 501 by inserting the electrode terminal 501, tightening the first female screw member 36 screwed onto the first male screw member 35 to clamp the electrode terminal 501 (Figs. 1, 4, 7, and 8). The second terminal connection portion 32 is formed in a flat plate shape in which the second male screw member 41 is assembled with the screw axis direction aligned in a direction orthogonal to the plane, and is directly or indirectly electrically connected to the first electrical connection portion 11 (Figs. 3, 6, and 7). In a state where the terminal fitting 30 is assembled to the electrode terminal 501, the plane of the second terminal connection portion 32 is orthogonal to the vertical direction. And the second male screw member 41 assembled to the second terminal connection portion 32 has its screw axis parallel to the central axis of the electrode terminal 501 and protrudes vertically upward from the second terminal connection portion 32 in a state where the terminal fitting 30 is assembled to the electrode terminal 501.

[0017] The first electrical connection portion 11 is jointly fastened and fixed to the second terminal connection portion 32 using the second male screw member 41 and the second female screw member 42 (Figs. 3 to 8). Therefore, the first electrical connection portion 11 is formed in a flat plate shape that is directly or indirectly electrically connected to the second terminal connection portion 32 by joint fastening. And a through hole 11a for inserting the second male screw member 41 is formed in the first electrical connection portion 11 (Fig. 7). The first electrical connection portion 11 inserts the second male screw member 41 into the through hole 11a and, for example, stacks the planes of the first electrical connection portion 11 and the second terminal connection portion 32 together. In the rescue terminal 10 and the terminal fitting 30, by tightening the second female screw member 42 from vertically above onto the second male screw member 41, the first electrical connection portion 11 and the second terminal connection portion 32 are jointly fastened and fixed, and both are electrically connected (Figs. 3, 6, and 7).

[0018] However, in this exemplary illustration, a flat electrical connection portion 601a of a bus bar 601 of a circuit protection component (such as a fuse or a fusible link) 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 exemplary illustration, the electrical connection portion 601a is laminated with the second terminal connection portion 32 with their planes aligned, and the first electrical connection portion 11 is laminated with the electrical connection portion 601a with their planes aligned. And, in this exemplary illustration, the first electrical connection portion 11, the second terminal connection portion 32, and the electrical connection portion 601a are clamped and fixed together by a second male screw member 41 and a second female screw member 42 to electrically connect them. Note that the circuit protection component 600 exposes the electrical connection portion 601a, and by laminating the electrical connection portion 601a with the second terminal connection portion 32, it is disposed on the side of the battery 500 (FIGS. 1 to 6).

[0019] The rescue terminal 10 is housed in a housing position (FIGS. 1 to 3) during normal times when rescue from a rescue vehicle, a portable battery, etc. is not required, and is displaced to a rescue position (FIGS. 4 to 6 and 8) above the vehicle relative to the housing position when being sandwiched by a clip 701 (FIG. 8) of a booster cable 700 and electrically connected to the clip 701. And, this rescue terminal 10 has a rotating portion 13 that rotates the second electrical connection portion 12 relative to the first electrical connection portion 11 between the housing position and the rescue position (FIGS. 3 to 8).

[0020] The rescue terminal 10 shown here is a press-formed product formed with 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. 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 (FIGS. 3 to 8).

[0021] This rescue terminal 10 has a bent shape, with the rotating portion 13 as the bending point, and is shaped so that the arrangement of the second electrical connection portion 12 relative to the first electrical connection portion 11 in that bent shape becomes the rescue position (Figures 4 to 8). In other words, this rescue terminal 10 has 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 rotating portion 13 connecting the first electrical connection portion 11 and the second electrical connection portion 12 at the position where the first electrical connection portion 11 and the second electrical connection portion 12 intersect. In this rescue terminal 10, it is desirable to arrange the first electrical connection portion 11 and the second electrical connection portion 12 so that the first direction and the second direction form a right angle or an obtuse angle in order to facilitate the connection work of the clip 701 at the rescue position.

[0022] Here, the first electrical connection part 11 and the second electrical connection part 12 form an obtuse angle. This rescue terminal 10 positions the second electrical connection part 12 vertically above the first electrical connection part 11 when the second electrical connection part 12 is in its hoisted position (Figure 3). In the rescue terminal 10 shown here, when the second electrical connection part 12 is in its hoisted position, the planes of the first electrical connection part 11 and the second electrical connection part 12 are perpendicular to the vertical direction, and the first electrical connection part 11 and the second electrical connection part 12 are positioned opposite each other with a gap between them in the vertical direction.

[0023] In this rescue terminal 10, where the first electrical connection part 11 and the second electrical connection part 12 form an obtuse angle, the rotating part 13 is formed as an elastically deformable part that can rotate the second electrical connection part 12 from the rescue position to the storage position relative to the first electrical connection part 11 within the elastic range. In this rescue terminal 10, by applying an external force toward the storage position to the second electrical connection part 12 in the rescue position (Figures 4 to 6), the rotating part 13 is elastically deformed, causing the second electrical connection part 12 in the rescue position to rotate toward the storage position relative to the first electrical connection part 11 (Figure 3). Then, in this rescue terminal 10, by stopping the application of the external force, the second electrical connection part 12 in the storage position returns to the rescue position while rotating toward the first electrical connection part 11 due to the elastic force accompanying the elastic deformation of the rotating part 13 (Figures 4 to 6).

[0024] Furthermore, the rotating part 13 shown here has a crank shape between the first electrical connection part 11 and the second electrical connection part 12 when the second electrical connection part 12 is in the housing position, in order to avoid the circuit protection component 600 (Figure 3).

[0025] 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 that rotates the opening / closing portion 22 between a closed position and an open position relative to the base portion 21 (Figures 1 to 3, 6 and 7).

[0026] The base portion 21 forms the basic framework of the cover 20 and also serves as a fixing part for securing the cover 20 to the vehicle. For example, this base portion 21 is fixed to the battery 500 side. The base portion 21 shown here also functions as a protective part that covers and protects the circuit protection component 600 from vertically above (Figures 2 and 3). For this reason, this base portion 21 is fitted and fixed to the circuit protection component 600 from the outside.

[0027] Here, the cover 20 has a retaining mechanism (hereinafter referred to as the "first retaining mechanism") 24 that holds the base 21 to the circuit protection component 600. This first retaining mechanism 24 includes a claw-shaped first locking portion 24a that protrudes from the inner wall of the base 21, and a claw-shaped second locking portion 24b that protrudes from the outer wall of the circuit protection component 600 and is positioned to lock the first locking portion 24a in the assembled position in order to hold the base 21 in that position while it is assembled to the circuit protection component 600 (Figure 3). This first retaining mechanism 24 is provided in multiple locations.

[0028] The opening / closing section 22 is rotatable between the storage position and the rescue position together with the second electrical connection section 12 which is in contact with the inner wall. In the storage position, the second electrical connection section 12 is covered and housed inside the cover (Figure 3), and in the open position, the second electrical connection section 12 in the rescue position is exposed and is clamped together with the second electrical connection section 12 by the clip 701 (Figures 4 to 6 and 8).

[0029] The opening / closing section 22 has a main wall portion 22a formed in a flat plate shape. For example, the second electrical connection portion 12 is made surface contact with the inner wall of the main wall portion 22a and rotated together with the second electrical connection portion 12 between the housing position and the rescue position (Figures 1 to 6). Also, when the opening / closing section 22 is in the closed position, its main wall portion 22a covers the second electrical connection portion 12 in the housing position from vertically above (Figure 3). Also, when the opening / closing section 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 (Figures 4 to 6 and 8). For this reason, the opening / closing section 22 does not have any protrusions or other factors that hinder insertion along the insertion trajectory of the clip 701 from one end of the main wall portion 22a. Here, the end of the main wall portion 22a opposite to the hinge portion 23 becomes the insertion point 22a1 of the clip 701 (Figures 3 to 8).

[0030] In this example of the rescue terminal 10, the first electrical connection part 11 and the second electrical connection part 12 face each other in the housing position. Therefore, in the cover 20, the cover body itself, which covers the rescue terminal 10 in the closed position, is used as the opening / closing part 22. For this reason, the opening / closing part 22 has side walls 22b and 22c extending downwards from a location on the main wall 22a that is the insertion point 22a1 of the clip 701, and the rescue terminal 10 is covered and protected by the main wall 22a and the side walls 22b and 22c. (Figures 1, 2, 4 and 5) The two side walls 22b and 22c are positioned opposite each other with a gap between them.

[0031] Furthermore, the opening / closing section 22 may cover the terminal fitting 30 together with the rescue terminal 10 when in the closed position. Also, the opening / closing section 22 may cover the positive electrode terminal 501 together with the rescue terminal 10 and the terminal fitting 30 when in the closed position. The opening / closing section 22 (cover body) shown here is formed to cover the rescue terminal 10, the terminal fitting 30 and the electrode terminal 501 when in the closed position (Figure 3).

[0032] Furthermore, in the case of the cover 20, when the second electrical connection part 12 is in the housing position, and the first electrical connection part 11 and the second electrical connection part 12 extend in opposite directions from the rotating part 13 (for example, when the first electrical connection part 11, the second electrical connection part 12 and the rotating part 13 form a crank shape), an opening / closing part 22 may be provided as a separate part from the cover body that covers the first electrical connection part 11 (not shown).

[0033] 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. It is desirable that this hinge portion 23 be positioned adjacent to the rotating portion 13 of the rescue terminal 10, so that the second electrical connection portion 12 does not separate from the inner wall of the main wall portion 22a of the opening / closing portion 22 as the second electrical connection portion 12 and the opening / closing portion 22 rotate (Figures 3 to 6 and 8). Furthermore, in order to avoid overloading between the second electrical connection portion 12 and the cover 20, it is desirable that the second electrical connection portion 12 be able to slide along the inner wall of the main wall portion 22a, with one end being the insertion starting point 22a1 of the clip 701 and the other end on the hinge portion 23 side, while remaining in contact with the inner wall of the main wall portion 22a as it rotates. Therefore, the opening / closing portion 22 may be provided with a guide portion for sliding the second electrical connection portion 12 as it rotates (not shown). This guide portion is, for example, the claw portion at the tip of a plurality of protrusions projecting from the inner wall of the main wall portion 22a, and the second electrical connection portion 12 is hooked onto these claw portions and held in a slidable state. Each of the protrusions is arranged opposite to the second electrical connection portion 12 in a direction perpendicular to the sliding direction.

[0034] The cover 20 has a holding mechanism (hereinafter referred to as the "second holding mechanism") 25 that holds the opening / closing section 22 in the closed position (Figures 4 and 7). The second holding mechanism 25 may hold the opening / closing section 22 in the closed position relative to the base 21, or it may hold the opening / closing section 22 in the closed position relative to a surrounding component. Here, the opening / closing section 22 in the closed position is held by the circuit protection component 600. The second holding mechanism 25 includes a claw-shaped first locking portion 25a (Figures 4 and 7) that protrudes from the inner walls of the side walls 22b and 22c of the opening / closing section 22, and a second locking portion 25b (Figure 7) provided on the circuit protection component 600 that hooks onto the first locking portion 25a when the opening / closing section 22 is in the closed position, thereby holding the opening / closing section 22 in the closed position. The side walls 22b and 22c of the opening / closing section 22 are made flexible. Therefore, in this opening / closing section 22, when rotated from the open position to the closed position, the first locking section 25a and the second locking section 25b can be positioned to lock with each other, and when rotated from the closed position to the open position, the locking state of the first locking section 25a and the second locking section 25b can be released.

[0035] In the rescue terminal 10, the elastic force generated towards the rescue position due to the elastic deformation of the rotating part 13 causes the second electrical connection part 12 in the hoisted position to exert force on the inner wall of the main wall part 22a of the opening / closing part 22. As a result, when the opening / closing part 22 is in the closed position, it flexes its respective side walls 22b and 22c, releasing the lockable state of the first locking part 25a and the second locking part 25b, and, receiving the force from the second electrical connection part 12, rotates together with the second electrical connection part 12 and displaces to the open position. Consequently, the second electrical connection part 12 and the opening / closing part 22 are positioned above the terminal fitting 30 and electrode terminal 501 on the vehicle. In other words, in this terminal block 1, opening the opening / closing part 22 to the open position causes the second electrical connection part 12 to protrude above the opening / closing part 22 on the vehicle compared to the opening / closing part 22 in the closed position.

[0036] Normally, no other components are placed above the vehicle above the closed opening / closing section 22, as this would interfere with rescue operations. However, in this example, the vehicle's hood is above the closed opening / closing section 22, but since the hood is opened during rescue operations, no other components are present above the closed opening / closing section 22. Therefore, during rescue operations, opening the closed opening / closing section 22 to the open position causes the second electrical connection section 12 and the opening / closing section 22 to protrude above the terminal fittings 30 and electrode terminals 501, and in a location where no other components are present. Consequently, this terminal block 1 allows for ample space to connect the clip 701 during rescue operations, making the connection of the clip 701 easier. Furthermore, since this terminal block 1 eliminates the need to connect the clip 701 to the electrode terminal 501 during rescue operations, there is no need to provide connection space for the clip 701 around the electrode terminal 501. For this reason, this terminal block 1 contributes to the compactness of the area around the electrode terminal 501.

[0037] Incidentally, the rescue terminal 10 may be formed in a bent shape with the rotating portion 13 as the bending point, bending toward the first electrical connection portion 11 side and the second electrical connection portion 12 side, and the arrangement of the second electrical connection portion 12 relative to the first electrical connection portion 11 in that bent shape is the housing position. In this case, the rotating portion 13 is formed as an elastically deformable portion that can rotate the second electrical connection portion 12 from the housing position to the rescue position relative to the first electrical connection portion 11 within the elastic range. In this rescue terminal 10, by applying an external force toward the rescue position to the second electrical connection portion 12 in the housing position, the rotating portion 13 is elastically deformed, and the second electrical connection portion 12 in the housing position is rotated toward the rescue position relative to the first electrical connection portion 11. Then, in this rescue terminal 10, by stopping the application of the external force, the second electrical connection portion 12 in the rescue position returns to the housing position while rotating relative to the first electrical connection portion 11 due to the elastic force accompanying the elastic deformation of the rotating portion 13.

[0038] When using such a rescue terminal 10, the cover 20 needs to hold the second electrical connection part 12 against the inner wall of the opening / closing section 22. For this reason, the opening / closing section 22 is provided with a holding part (not shown) for holding the second electrical connection part 12 in contact with its inner wall. This holding part is, for example, the claw portion at the tip of a plurality of protrusions that protrude from the inner wall of the opening / closing section 22, and the second electrical connection part 12 is hooked onto these claw portions to hold the second electrical connection part 12 against the inner wall of the opening / closing section 22.

[0039] Furthermore, in this case, it is necessary to ensure that the second electrical connection part 12 at the rescue position does not return to its storage position by elastic force during rescue. For this reason, the cover 20 is provided with a holding mechanism (hereinafter referred to as the "third holding mechanism") that holds the opening / closing part 22 in the open position (not shown). This third holding mechanism, for example, holds the opening / closing part 22 in the open position relative to the base 21. This third holding mechanism comprises a claw-shaped first locking part protruding from the opening / closing part 22, and a second locking part provided on the base 21 that hooks onto the first locking part when the opening / closing part 22 is in the open position, thereby holding the opening / closing part 22 in the open position.

[0040] In this case as well, terminal block 1 can achieve the same effect as in the previous example. [Explanation of Symbols]
