In addition, on the upper surface of the base portion 51 of the pedestal portion 42, a screw hole for the trunk of the terminal board 1 is formed.
A trunk terminal hole 82 is provided in the extension direction of 81, and a branch terminal hole 92 is provided in the extension direction of the branch screw hole 91 of the terminal board 1. As shown in FIG. After passing the terminal screw 83 for trunk or the terminal screw 93 for branch into the holes of the circular parts 85, 95 of the terminal plate 1, while screwing the screw hole 81 or 91 of the terminal board 1, the terminal hole 81 for trunk or branch of the pedestal 42 The tip portion is inserted into the terminal hole 92 for use. As a result, the main electric wire is connected to each branch electric wire through the terminal board 1 for distribution connection.

The base portion 51 and the partition wall portion 41 are provided with assembling bolt 71 holes penetrating from the front end to the rear end of the pedestal portion 42, and the bolt holes 70 are also extended to the partition wall body 3 at the rear end of the pedestal portion 42. A bolt hole 75 is formed at a position in the direction, and this bolt hole 70,
75 through the bolt 71, the partition wall 41 and the outer surface of the partition body 3,
That is, the insulating base 4 and the partition wall 3 can be integrally connected by tightening the nuts 72 from the front and rear ends of the main body 2.

Here, the pedestal portion 42 is provided on both inner and outer side surfaces of the partition wall 41 of the insulating base 4.
Holding grooves 39, 49 are formed along the joint edge with the partition wall 3, and on the other hand, holding grooves 39, 49 of the same shape are formed on both inner and outer side surfaces of the partition wall 3 along the joint edge with the pedestal portion 42. There is. That is, the holding grooves 39, 49 have a shape that conforms to the shapes of the front and rear edges of the terminal block A fitted and mounted on the upper surface of the pedestal portion 42, without loosely fitting the front and rear edges. The groove width is such that it can be fitted. Further, the length from the front end to the rear end of the terminal board 1 is substantially equal to the length from the bottom of the holding grooves 39, 49 of the partition wall 41 of the main body 2 to the bottom of the holding grooves 39, 49 of the partition body 3. . With such a configuration, the terminal plate 1 is mounted on the pedestal portion 42, and both ends thereof are fitted and held between the holding grooves 39 and 49 of the partition wall portion 41 and the partition wall body 3 to be held and fixed to the main body 2. Of.

Further, projections 45 and 35 are provided on both the left and right sides of the partition wall 41 and the partition wall 3 so that the terminal plate 1 placed on the pedestal 42 is inadvertently moved upward. Even the terminal board 1
The upper surface of the terminal abuts on the lower ends of the protrusions 35 and 45 so that the terminal plate 1 can be prevented from coming out upward. Also, the protrusions 35,4
5, the notch portions 36 and 46 are provided along the outer edge of the round portion 95 of the crimp terminal 90 to be attached, and the tips of the protrusions 45 and 35 are adjacent to the crimp portion 99 of the crimp terminal 90. Therefore, when the crimp terminal 90 is attached, the protrusions 35 and 45 come into contact with the crimp terminal 90 to prevent accidental rotation of the crimp terminal 90.

Here, notches 38, 4 for fixing the main body 2 are provided on both sides below the outer surface of the partition wall 41 of the insulating base 4 and both sides below both surfaces of the partition body 3.
Bosses 37 and 47 having 8 are projected. A notch 55 for accommodating the boss 37 of the partition wall 3 is provided at a lower portion of the pedestal portion 42 of the insulating base 4 at least at a rear end portion where the boss 37 is located. As a result, the bosses 37 and 47 on the inner surface side of the partition wall 3 are housed in the notch 55 at the bottom of the insulating base 4, and the partition wall 3 is seated on the pedestal portion 4.
The main body 2 is assembled by closely contacting the rear end of the main body 2.
Is fixed to the mounting surface by mounting screws via the bosses 37 and 47 at the front and rear ends.

Hereinafter, a method of assembling and attaching the main branch terminal block A of this embodiment will be described. Fit the lower surface of the terminal plate 1 onto the upper surface of the pedestal portion 42 of the insulating base 4 so that the projections 35 and 45 are not caught by the mounting.
The front end edge of the terminal board 1 is fitted into the holding groove 49 of the partition wall 41 by sliding it slightly, and the bosses 37 and 47 on the inner side surface of the partition wall 3 are housed in the notches 55 under the pedestal part 42 while the partition wall body is accommodated. 3 is brought into contact with the rear end of the pedestal, and in this state, the bolt 71 is passed through the bolt holes 70 and 75 penetrating from the insulating base 4 to the partition wall body 3, and the nut 72 is screwed from both sides of the main body 2 to make the main body 2 Tighten the nuts 72 on both sides to fix them. The main body 2 is fixed by tightening and fixing the bosses 37 and 47 at the lower ends of both side surfaces of the main body 2 to the mounting surface with a mounting screw. As described above in this embodiment, in the main branch terminal block A of the present invention, the terminal plate 1 is held between the holding grooves 39 and 49 at the time of assembling the main body 2 and not above the terminal plate 1 without screwing. Since the protrusions 35 and 45 are provided to prevent disconnection, and the tips of the protrusions 35 and 45 are further adjacent to the crimp portion 98 of the connected crimp terminal 90, the protrusions 35 and 45 are connected to the insulating base 4 of the terminal board 1. It is possible to simplify the fixing method, simplify the component processing and assembly process, and prevent the crimp terminal from rotating. Further, since the upper surface of the convex base portion 51 of the main body 2 is fitted into the concave portion 16 of the terminal plate 1, it is possible to prevent the left and right runout of the crimp terminal 90 about the branching terminal screw 93. It is possible to secure the insulation dimensions.

Here, a plurality of the main branch terminal blocks A of this embodiment can be continuously connected. That is, the partition wall portion 41 of the insulating base 4 has the above-mentioned projections 35, 45 and the holding grooves 39,
Since 49 is provided, the partition wall portion 41 of the insulating base 4 can be attached to the rear end of the other insulating base 4 in the same manner as the partition wall body 3, and after connecting a plurality of them, the partition wall body 3 is finally attached to the insulating wall. A bolt of a predetermined length can be passed through the hole of the bolt 71 by abutting on the rear end of the bolt, and the nut 72 can be tightened and fixed from both sides.

[Effect of device]

The main branch terminal block of the present invention comprises a conductive terminal plate having a screw hole to which a crimp terminal is screwed, a base on which the terminal plate is placed, and an inner side surface of the inner and outer side surfaces connected to the base section. At least one of the inner and outer side surfaces is fixed at a position facing the partition of the insulating base, and an insulating base having a partition for fitting and sandwiching the front end or the rear end of the terminal plate with the holding groove provided. In a main branch terminal block with a partition body that fits and holds the rear end portion or the front end portion of the terminal plate in the holding groove provided on the side surface, on the inner side surfaces of the inner and outer side surfaces of the partition wall portion and the partition wall body, A protrusion is provided in the vicinity of the upper surface of the placed terminal plate so that the tip is adjacent to the crimping portion of the crimp terminal, and at the base portion, the tip is provided so as to protrude from the vicinity of the side surface of the placed terminal plate. Since the terminal fixing part located below the upper surface of the plate is provided, parts processing and assembly Even if the stand is simplified and the external force such as pulling the crimp terminal is applied, the protrusion can prevent the crimp terminal from rotating, and the side wall can absorb the external force to prevent the terminal plate from being displaced. It has the effect of making the body hard to break.
