Description

  The present invention relates to an electric junction box for automobiles, and more specifically, a plurality of terminals projecting from a printed circuit board accommodated in a case are connected to a block connector and a wire harness connected to the connector is branched. To connect.

Conventionally, as this type of electrical connection box, Japanese Patent Application Laid-Open No. 2004-248401 has provided an electrical connection box shown in FIGS. 7A, 7B, and 7C. As shown in FIG. 7A, the electrical junction box has a male terminal insertion hole formed by arranging a circuit forming body 102 held by the case cover 101 from the outer surface of the base wall 100a of the case 100 and drilled in the base wall 100a. The male terminal 103 projecting from the circuit forming body 102 is inserted into 100b, the center insertion hole of the male terminal insertion hole 100b is made small to be a positioning reference hole 100c, and the male is inserted into the positioning reference hole 100c through a small gap. It is disclosed that the circuit forming body 102 is guided and held at a predetermined position through the terminal 103.
A large number of stacked connectors 105 are fitted to the case 100 in the male terminals 103, the male terminals 103 are inserted into the terminal accommodating chambers in the respective connectors 105, and the electric wires inserted and locked in these terminal accommodating chambers. The female terminal of the terminal is fitted and connected.
Each of the plurality of connectors 105 is provided with an engagement recess 105 a that engages with an engagement claw portion 100 d provided on the case 100, and is locked to the case 100.

Japanese Patent Laid-Open No. 2004-248401

In the electrical junction box, when the male terminal of the circuit forming body 102 is set in the case 100, the male terminal is inserted into the male terminal insertion hole formed in the base wall 100a of the case so as to protrude into the case cover 100. It is described that a male terminal 103 is inserted by providing a reference hole 100c. However, as shown in FIG. 7C, when the lengths of the male terminals 103 are equal, the smaller reference hole 100c has a male terminal 103 than the other male terminal insertion holes 100b. It becomes difficult to insert. Therefore, as described in Patent Document 1, it is unclear whether “the circuit forming body 102 is guided and held at a predetermined position through the male terminal 103 through a small gap in the positioning reference hole 100c”.
Further, since the terminal insertion hole 100b including the reference hole 100c is formed in the base wall 100a of the case 100, a large number of pin-shaped male terminals protruded from the base wall 100a with relatively long dimensions are simultaneously inserted into each terminal. In the operation of inserting through the hole 100b, the male terminal is likely to be deformed or damaged unless the alignment accuracy is increased.
In addition, since the large number of male terminals protruding from the circuit forming body only protrude through the large male terminal insertion hole 100b, the male terminals can be inserted into the terminal accommodating chamber on the connector side even if the positional accuracy is poor. There is a risk of semi-fitting.

  Furthermore, in Patent Document 1, engagement concave portions 105a are provided on both side walls of a large number of stacked connectors 105, respectively, and engaged and locked with engagement claw portions 100d on the case 100 side. It is described as being inserted into 100. As described above, when each connector 105 is configured to be locked and coupled to the case 100, both the connector side and the case side have a complicated configuration, and if a large number of connectors 105 are individually inserted into the case, work is required. There is also a problem.
