<Explanation of Embodiments of the present disclosure>
First, embodiments of the present disclosure will be listed and described.
The terminal block of this disclosure is
(1) A terminal block for relaying an electrical connection between a first device and a second device, which is a laminated body formed by laminating a plurality of thin plates and having conductivity and flexibility, and the laminated body. The laminate comprises a first end portion, a second end portion arranged on the opposite side of the first end portion, and the first end portion and the first end portion. It has an intermediate portion arranged between the two ends, the first end has a first terminal that is electrically connectable to the first device, and the second end has. It has a second terminal portion that can be electrically connected to the second device, the intermediate portion is covered with the housing and fixed to the housing, and the first end portion and the first end portion are fixed to the housing. The two ends are those exposed from the housing.

According to the terminal block of the present disclosure, the first end portion of the laminated body has the first terminal portion, and the second end portion opposite to the first end portion has the second terminal portion. .. Then, the intermediate portion between the first end portion and the second end portion is covered and fixed by the housing. Therefore, the intermediate portion of the laminated body is held by the housing, and the laminated state of the thin plates is stably maintained. Further, by fixing the intermediate portion of the laminated body to the housing, the first terminal portion and the second terminal portion are positioned with respect to the housing. In addition, the first end portion and the second end portion exposed from the housing can be bent and deformed in the stacking direction of the thin plates. This makes it possible to absorb the assembly tolerance between the first device and the second device. The bending characteristics of the first end and the second end are appropriately set by adjusting the amount of protrusion of the first end and the second end from the housing, the shape and material of the thin plate, the number of laminated sheets, and the like. can do.

Further, unlike the conventional structure in which the first terminal portion and the second terminal portion are connected by braiding of separate members, the first terminal portion and the second terminal portion are formed by the same laminated body. .. Therefore, it is possible to reduce the types of parts and reduce the processing man-hours for connecting them. Furthermore, compared to the case where a braid is used for tolerance absorption, the risk of the thin plate constituting the laminated body being cut due to contact with surrounding members is reduced, so that the conduction stability of the terminal block is improved. Improvements are also being made.

(2) The first terminal portion further includes a fixing portion for fixing the plurality of thin plates in the intermediate portion of the laminated body to each other, and the first terminal portion has a first through hole penetrating the plurality of thin plates. The terminal portion preferably has a second through hole that penetrates the plurality of thin plates. Since the plurality of thin plates are fixed by the fixing portion in the intermediate portion of the laminated body, it is possible to suppress the mutual positional deviation of the through holes in the plurality of thin plates constituting the first through hole and the second through hole. As the fixing portion, any structure can be adopted as long as it integrally fixes a plurality of thin plates. For example, the fixing portion can be configured by a caulking part that integrally crimps a plurality of thin plates, a welded portion that welds the plurality of thin plates to each other, a resin block that integrally embeds the plurality of thin plates, and the like.

(3) In the above (2), the fixing portion is made of synthetic resin and the intermediate portion is embedded, and the fixing portion is arranged between the housing and the laminated body. preferable. For example, by molding the fixed portion in a state where the intermediate portion of the plurality of thin plates is inserted into the molding die of the fixed portion, fixing of the plurality of thin plates and molding of the fixed portion can be achieved at the same time. As a result, when fixing a plurality of thin plates in a laminated state, it is possible to eliminate time-consuming processing such as caulking and welding, and reduce the processing man-hours. Further, the housing can be formed with the thin plate fixed by the fixing portion, and the manufacturing efficiency of the housing and the terminal block can be improved.

(4) It is preferable that the housing has a flange portion for fixing to one of the first device and the second device. In addition to the function of holding the laminated body, the housing can also have a function of fixing to the first device or the second device, eliminating the need for a separate bracket or the like, and reducing the number of parts.

(5) It is preferable that the laminated body has a bent portion that bends in a direction orthogonal to the laminating direction of the plurality of thin plates. For example, even when it is difficult to connect the first device and the second device by a straight extending laminate, the first device and the second device can be avoided by providing a bent portion in the laminate. It becomes possible to connect with. That is, by providing the bent portion in the laminated body, the degree of freedom in the shape of the laminated body and the degree of freedom in selecting the arrangement mode in the peripheral members are improved.

(6) It is preferable that there are a plurality of the laminated bodies, and each of the plurality of laminated bodies has the same shape. Since each of the plurality of laminated bodies has the same shape, the shapes of the thin plates constituting the laminated body are also the same, and a plurality of laminated bodies can be formed by using one kind of thin plates. Therefore, the number of types of parts can be reduced and parts management becomes easy.

(7) In any one of the above (1) to (5), it is preferable that there are a plurality of the laminated bodies, and each of the plurality of laminated bodies has a different shape from each other. Since each of the plurality of laminated bodies has a different shape from each other, it becomes easy to adjust the shape of the plurality of laminated bodies according to the arrangement mode of the peripheral members.

The terminal block 50 shown in FIG. 6 has the same shape as that of the first embodiment except for the shapes of the first to third laminated bodies 52a to 52c, and has substantially the same members and members as those of the first embodiment. The parts are designated by the same reference numerals as those in the first embodiment in the drawings, and detailed description thereof will be omitted.

(2) In the embodiment shown in the first embodiment and FIG. 6, the first to third fixing portions 48a to the housing 20 are between the first to third laminated bodies 18a to 18c, 52a to 52c and the housing 20. Although 48c was provided, the fixed portion is not essential in the terminal block according to the present disclosure. That is, when molding the housing, the intermediate portion of the laminated body may be set in the molding cavity of the housing and the housing may be molded so that the intermediate portion of the first to third laminated bodies is directly fixed by the housing. ..

(3) In the embodiment 1 and the embodiment shown in FIG. 6, three laminated bodies (first to third laminated bodies 18a to 18c and 52a to 52c) are provided, respectively, but the number of laminated bodies is provided. Is not limited to three, and may be one, two, four or more. Further, in the embodiment 1 and the embodiment shown in FIG. 6, three fixing portions 48 (first to third fixing portions 48a to 48c) are provided, but the number of fixing portions is also limited to three. It may be one, two, four or more. It should be noted that the number of laminated bodies and the number of fixed portions do not have to match, and for example, one fixing portion may be provided to cover and fix the intermediate portion of the plurality of laminated bodies.

(4) The number of thin plates constituting the laminated body is not limited, and may be a plurality of (two or more). The thickness dimension and the number of thin plates can be appropriately set according to the required conductive performance, bendability, and the like.

(5) In the embodiment shown in the first embodiment and FIG. 6, each of the plurality of first to third thin plates 16a to 16c has a square tube shape made of synthetic resin in the intermediate portion 26. It was fixed by the first to third fixing portions 48a to 48c, but the fixing portion is not limited to this. That is, the plurality of thin plates can be fixed at the intermediate portion by caulking, welding, bonding, or other conventionally known fixing means. For example, the fixing portion may be formed by a caulking part provided separately from the thin plate, or a caulking piece protruding outward in the width direction (left-right direction) in the middle portion of the top or bottom thin plate. .. Then, a plurality of thin plates may be caulked and fixed in the intermediate portion by bending the caulking part or the caulking piece. Alternatively, the thin plates may be bonded (welded) to each other in the intermediate portion by providing a coating film for joining on the surface of the thin plates and melted, or the thin plates may be bonded to each other in the intermediate portion with an adhesive. In this case, the fixing portion is formed by the coating film or the adhesive. Even when a square tube-shaped fixing part is adopted, it is fixed by forming the fixing part with an elastic material such as rubber or elastomer, expanding the inner hole of the fixing part, and inserting a plurality of thin plates. A plurality of thin plates may be fixed in a laminated state by the inward urging force accompanying the elastic restoration deformation of the portion. That is, the shape and material of the fixing portion are not limited, and a plurality of thin plates may be fixed in a laminated state in the intermediate portion of the laminated body. Further, such a fixing portion may be able to maintain a laminated state of a plurality of thin plates at the time of molding the housing, and displacement of the thin plates may be allowed to some extent except at the time of molding the housing.
