Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an improvement of intermediate connection terminals used in electrical connection boxes of automobiles and the like.

(Prior art) As shown in Fig. 4, this type of conventional intermediate connection terminal has blade holders on both the left and right sides of a rectangular conductive metal plate by bending both side edges inwardly into a semicircular arc shape. 11, and when the male terminals are inserted into the blade receiving part 11 of the intermediate connection terminal 10 from above and below from above, the terminals are bent from the sides of both inserted terminals. The spring force of the blade receiving portion 11 acts to press the blades into contact with each other. Therefore, as shown in FIG.
When automatically assembling the electrical junction box 14 by sequentially inserting them into the male terminals 12 arranged in a row on the bus bar arranged in the electrical junction box 14 from above, the male terminals 12 of the bus bar and the intermediate connecting terminal 10 blade receivers 1
1 and 1, vibrations during assembly may cause the male terminal 12 of the bus bar to be disconnected from the intermediate connection terminal 1.
0 easily falls off, and each time the intermediate connection terminal 10 that has fallen off has to be reinserted into the male terminal 12 of the bus bar, the work is very complicated and troublesome. In addition, since the intermediate connection terminal 10 has a certain amount of clearance in the blade receiving part 11 to facilitate insertion of the male terminal, the lid 15 placed on the electrical connection box 14 is drilled. The blade receiving portion 11 of the intermediate connection terminal 10 is inserted from the terminal insertion port 16 of the
The male terminal 13 of an electrical device such as a fuse, which is inserted into the bus bar and press-contacted with the male terminal 12 of the bus bar, is not inserted into the center of the blade receiving part 11 of the intermediate connection terminal 10,
As shown in FIG. 6, electrical equipment such as fuses exposed on the surface of the lid 15 of the electrical junction box 14 is not aligned properly and the aesthetic appearance is not only spoiled, but also the blade holder 11 of the intermediate connection terminal 10 is not aligned with the electrical equipment. male terminal 13
The disadvantages include that there is a risk that the connector may be strained due to vibration when it is inserted or removed, resulting in poor contact.

(Structure of the present invention) The present invention was made to solve the above-mentioned drawbacks, and the left and right edges of a conductive metal plate, each of which has two protruding tongues parallel to the upper and lower edges formed by punching, are inserted into each other. The contact piece is characterized in that the blade is bent in the opposite direction to form a semi-circular-arc-shaped blade receiver, and the two protruding tongues are folded into the semi-circular-arc-shaped blade receiver so as to face each other to form a contact piece. It is.

(Embodiment of the present invention) Hereinafter, an embodiment of the present invention will be explained with reference to the drawings. As shown, there are two protruding tongues 3a and 3b on both upper and lower edges.
A conductive metal plate is formed by punching, and both edges of the conductive metal plate formed by the punching are bent inwardly into a semicircular arc shape to form the blade receiving part 2. The two protruding tongues 3a, 3 are provided in the arcuate blade receiving portion 2.
Fold the contact pieces 3, 3 so that they face each other.
It is formed by forming. This intermediate connection terminal 1
As shown in FIG. 3, male terminals 12 and 13 of electrical equipment such as a bus bar and a fuse, which are respectively inserted into the blade receiving part 2 from above and below the intermediate connecting terminal 1, are inserted into the blade receiving part 2 from above and below. The contact pieces 3, 3, which are folded in opposite directions, are positioned in the center of the blade holder 2 so that they overlap accurately, and are firmly pressed and fixed by the spring force of the bent blade holder 2. It is becoming more and more common.

(Effects of the present invention) The present invention is as described above, and the left and right edges of a conductive metal plate, in which two protruding tongues 3a and 3b are punched in parallel to the upper and lower edges, are half-shaped inwardly. A blade receiving part 2 is formed by bending it into an arc shape, and contact pieces 3, 3 are provided by folding the two protruding tongues 3a, 3b so as to face each other in the semicircular blade receiving part 2. As a result, the electrical junction box 14 is automatically opened by sequentially inserting the blade receivers 2 of the plurality of intermediate connection terminals 1 into the bus bar arranged in the electrical junction box 14 from above the male terminals 12 arranged in a row. When assembling, the contact pieces 3, 3, which are folded into the blade receiving part 2, are pressed against both sides of the male terminal 12 of the bus bar by their own spring force, so that the assembly process is not as easy as in the conventional case. The intermediate connection terminal 1 does not fall off from the male terminal 12 of the bus bar due to vibrations, etc., and the automatic assembly of the electrical connection box 14 is performed extremely smoothly, improving productivity. A male terminal 13 such as a fuse is inserted into the blade receiving part 2 of the intermediate connecting terminal 1 through the terminal insertion opening 16 formed in the lid body 15. , 3 is guided to the center of the blade receiving part 2, completely overlaps with the male terminal 12 of the bus bar, and is fixed by pressure contact, so that the blade receiving part 2 of the intermediate connection terminal 1 is guided to the center part of the male terminal 1 of the intermediate connection terminal 1.
There is no risk of a contact failure being caused by the vibration of the connection box 3 being inserted or removed, and there is also no possibility that electrical equipment such as fuses exposed on the surface of the lid 15 placed over the electrical connection box 14 may become misaligned. It has great advantages such as:
