FIG. 1 is a perspective view showing a state in which the substrates 1 and 1 of the present invention are connected to each other by a clip 2.
2 is a perspective view showing a state where the substrates 1 and 1 are not connected, FIG. 3 is a perspective view immediately before the substrates 1 and 1 are connected to each other by a clip 2, and FIG. FIG. 5 is a sectional view showing a state in which the substrates 1 and 1 are connected to each other by a clip 2.
(About this butt connection structure between the substrates 1 and 1)
As shown in FIGS. 1 and 4, the butt connection structure between the substrates 1 and 1 is configured such that the butt portion between the substrates 1 and 1 and the vicinity thereof are sandwiched and connected by the clip 2. Misalignment does not occur.

For this reason, the substrate 1 and the clip 2 have the following structure.
(Regarding the configuration of the substrate 1)
The base plate BP as a whole is formed in an annular shape as shown in FIGS. 1 and 2 in the assembled state, but is formed by integrating two semicircular substrates 1 and 1 with a clip 2. is there. Here, this substrate BP is the wrist (arm) of the manipulator
A plurality of rail-like arc-shaped wirings that are in contact with a brush (not shown) are formed.

As shown in FIG. 2 and FIG. 3, through holes 10 are formed in the vicinity of the outer peripheral edge slightly apart from the abutting portions of the adjacent substrates 1 and 1, respectively, and in the vicinity of the one through hole 10. A slit 11 extending from the outer peripheral edge toward the inner peripheral edge is provided.
(About the structure of clip 2)
The clip 2 is formed by pressing a spring steel plate, and includes a pair of sandwiching plates 20 and 21 and a back plate 22 connecting the two as shown in FIG.

  As shown in FIGS. 3 and 4, the sandwiching plate 20 is configured by a flat plate having a rectangular shape when viewed from above, and two protrusions 20 a are formed by denting two points corresponding to the through holes 10. In addition, there is provided an insertion piece 20b for preventing erroneous insertion that extends toward the sandwiching plate 21 on one side (short side). The sandwiching plate 20 extends at an angle of 90 ° with respect to the back plate 22.

As shown in FIG. 3, the clamping plate 21 is a portion that functions as a clamp portion, and extends in a direction away from the clamping plate 21 after extending from the lower end portion of the back plate 22 at an angle of about 45 °. . That is, the sandwiching plate 21 extends in a letter shape from the lower end of the back plate 22 in a side view. The distance between the top of the substantially plate-shaped cross section of the sandwiching plate 21 and the sandwiching plate 20 is set slightly smaller than the thickness of the substrate 1.
(Method of connecting substrates 1 and 1 in a butted state by clip 2)
(1) As shown in FIGS. 1 and 3, the substrates 1 and 1 are brought into contact with each other and maintained in that state.
(2) As shown in FIG. 3, the pair of clamping plates 20 and 21 of the clip 2 are opposed to each other at the portion where the substrates 1 and 1 are abutted with each other, and the clip 2 is pushed in. Then, as shown in FIG. 5, the insertion piece 20b is inserted into the slit 11, and the protrusions 20a and 20a are fitted into the through holes 10 and 10 of the substrates 1 and 1 that are abutted.
(3) In the state of (2) above, since the interval between the top of the substantially plate-shaped cross section of the sandwiching plate 21 and the sandwiching plate 20 is set slightly smaller than the thickness of the substrate 1, the substrates 1 and 1 are brought into contact with each other. The portion and the vicinity thereof are firmly sandwiched between the sandwiching plates 20 and 21, and are corrected so that there is no step between the substrates 1 and 1 with reference to the flat plate surface of the sandwiching plate 20 constituting the clip 2. Further, since the protrusions 20a and 20a of the clip 2 are fitted in the through holes 10 and 10 formed in the substrates 1 and 1, there is no positional deviation other than the step between the substrates 1 and 1. Since the clip 2 is formed by pressing a spring steel plate, the clip 2 is not loosened by vibration, and the clip 2 is not accidentally dropped from the substrates 1 and 1.

In the case of (2) above, in the case of a slit, since the insertion piece 20b is inserted into the slit 11, the projections 20a, 20a of the clip 2 are fitted into the through holes 10, 10, but the slit 11 When the clip 2 is pushed into the butted portion of the substrates 1 and 1 and the vicinity thereof in a state where the insertion piece 20b is not inserted into the insertion piece 20b, the projections 20a and 20a of the clamp 2 are fitted into the through holes 10 and 10, respectively. There is nothing. Therefore, if the substrates 1 and 1 having the slits 11 and the clamp 2 having the insertion piece 20b are used, the erroneous insertion of the clip 2 with respect to the substrates 1 and 1 can be completely prevented.
(The excellent point of this butt connection structure between the substrates 1 and 1)
As is apparent from (3) in the above-mentioned section (Method of connecting the substrates 1 and 1 in the butted state by the clip 2), this connection structure has an excellent function as described below.
(1) A butt connection with no step and other misalignment can be made easily.
(2) Since the clip 2 is formed by pressing a spring steel plate, the clip 2 is not loosened by vibration, and the clip 2 is not inadvertently dropped from the substrates 1 and 1.
(3) Since the clip 2 can be formed simply by pressing a spring steel plate, the cost can be reduced.
(Other embodiments)
In the first embodiment, the substrate 1 is arcuate, but it can be linear.

  In the first embodiment, the slit 11 and the insertion piece 20b are provided. However, the invention is not limited to this, and the slit 11 and the insertion piece 20b may not be provided.
