Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector housing for connecting male terminals without using relay female terminals.

According to the present invention, it is possible to directly connect the blade terminal of a blade type fuse used for electrical wiring in an automobile, for example, to the tab terminal of a bus bar (circuit) in a junction block.

[Conventional technology]

The blade type fuse F is as shown in Fig. 4.
It has a configuration in which the head of an H-shaped fuse main body 3, in which the upper end portions between a pair of blade terminals 1, 1 are connected by a fuse link 2, is covered with an insulator 4.

In addition, as shown in FIG. 5, the junction block is constructed by stacking a plurality of wiring boards 7 each having a busbar 5 arranged on an insulating substrate 6 and housing them in a case body 8. It is configured by covering it with the provided case cover 11. The bus bar 5 is integrally formed by punching and bending a metal plate, leaving the connecting piece 5a, and tab terminals 1 are attached at key points.
After disposing on the insulating substrate 6, the connecting pieces 5a are separated to make each circuit independent. Note that 6a is a punched hole for the connecting piece 5a;
b is a tab terminal through hole.

Since both the blade terminal 1 and the tab terminal 12 are plate-shaped male terminals, relay female terminals 13 and 14 as shown in FIGS. 6a and 6b have conventionally been used to connect them. 60-13190).

However, the use of such relay female terminals (1) increases the number of parts and assembly man-hours when assembling the junction block and connecting to relays, etc.; Contact resistance increases due to the presence of the terminals, and (3) the junction blocks, relays, and fuse holders 9 and 10 become bulky and large due to the height of the relay terminals. .

[Problem that the invention attempts to solve]

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector housing that solves the above problems and allows direct connection between male terminals without using relay female terminals.

[Means for solving problems]

To explain with reference to the drawings, the connector housing H for connecting between male terminals of the present invention, as shown in Figs. A surrounding wall 20 of the shape is provided. An insertion position regulating wall 21 for the male terminal (blade terminal) 1 inserted from the outside into the upper end opening of one inner wall 20a facing the surrounding wall 20
to protrude. Further, the male terminal (tab terminal) 12 housed inside is extended from both left and right sides of the inner wall 20a toward the other inner wall 20b so as to guide and wrap it, and its free edges are turned inward to form a U-shape. A terminal holding plate 23 having an uneven portion 23a formed on the inner surface is provided at the end edge of a pair of elastic plate portions 22 which are curved 22a. The terminal holding plate 23 and the male terminal 12 housed inside along the inner wall 20a each sandwich the male terminal 1 inserted from the outside between them, and the male terminal 1
2 and 1 are electrically connected to each other.

[Effect]

According to the present invention, the male terminal 1 inserted from the outside of the connector housing H enters between the male terminal 12 housed along one inner wall 20a of the enclosure wall 20 and the terminal holding plate 23, A pair of elastic plate parts 2
By the spring force of the terminal holding plate 23 supported by the terminals 2 and 2, the male terminals 12 are pressed against each other and come into surface contact with each other, thereby establishing an electrical connection.

Therefore, there is no need for the conventional female relay terminal, and the male terminals can be connected as is.
It is possible to avoid increasing the bulk and size of the enclosure wall due to the interposition of the relay female terminal.

In addition, the insertion position regulating wall 21 at the upper end opening of the enclosure wall 20 allows the male terminal 1 from the outside to
2 and the inner wall 20a, and cooperates with the opposing terminal holding plate 23 to act as an insertion guide for the male terminal 1.
Even if there is some misalignment between the two, the insertion and connection can be made smoothly. Further, since the terminal holding plate 23 reliably presses the male terminal 1 against the male terminal 12 side by the uneven portion 23a, a stable contact state can be obtained.

[Embodiment]

The connector housing H shown in FIGS. 1 to 3 is a typical example of the present invention, and has an enclosure wall 20, which is a housing main body, integrated with the case cover 11 (see FIG. 5), and has male terminals. Reference numeral 12 indicates a tab terminal connected to the bus bar 5 in an upright manner.

By integrating the connector housing H with the junction block or case cover in this way, the following effects can be obtained.

Since no relay female terminal is required, the height of the housing such as the relay holder (see FIG. 5) can be reduced, and the entire junction block can be downsized.

When assembling the wiring board 7 shown in FIG.
After separating the connecting pieces 5a, these can be fixed by covering the case cover 11 as is. That is, in the conventional method, for connecting the relay female terminal, the connecting piece 5a floats on the bus bar 5,
Misalignment occurred, and a process of fixing it to the substrate with adhesive was necessary. However, by providing the enclosure wall 20 on the case cover 11, the bus bar 5
Since the male terminal 12 is positioned and fixed, the above steps can be omitted.

Furthermore, by omitting the above steps and reducing the number of parts, it is possible to improve workability and reduce costs in assembling the junction block.

In addition, the connector housing H of the present invention does not integrate a case cover etc. as described above.
It can be used independently like a normal male-female connector housing.

[Effect of idea]

As described above, according to the present invention, male terminals can be directly connected to each other without the need for a relay female terminal, and by applying this to electrical equipment such as a junction block, It is possible to reduce the size, improve assembly workability, and reduce costs.
