[Problems to be solved by the device]

 However, the above-mentioned joint connector requires four members, that is, the joint terminal 1, which is made of a metal member, the cover housing 2, the connector housing 3, and the crimp terminal 6, and thus has a drawback of increasing the number of parts. In addition, with the increase in the number of parts, it is necessary to fit the cover housing 2 to which the joint terminal 1 is fixed in advance to the connector housing 3 after mounting the required number of terminals 6 on the connector housing 3, which requires a lot of man-hours. However, there was a drawback that the cost increased.

Further, when the joint terminal 1 is fixed to the cover housing 2, the convex locking portion 1c of the joint terminal 1 is press-fitted into the groove 2b provided in the bottom portion 2a of the cover housing 2 for processing. Therefore, the metal member forming the joint terminal 1 cannot be completely inserted even if the metal member is slightly deformed. In particular, in a multi-pole joint connector, there is a problem that it is very difficult to align the engaging portion 1c of the joint terminal with the groove of the cover housing 2.

The present invention has been made in view of the above problems, and it is possible to reduce the number of parts by eliminating the need for a cover housing and a joint terminal, and thus to reduce the number of work steps and cost. Has an aim.

A recessed slit 11b-2 is provided which is further opened to the rear end bottom portion 11c.

Further, in the connector housing 11, as shown in FIG. 2, a lance portion 11g is provided on the lower wall 11f of the connector housing 11 so as to project toward the inside of the terminal accommodating chamber 11a. 11g is inclined downward toward the opening side of the terminal accommodating chamber 11a.

The crimp terminal 12 connected to the primary wire 5A on the power source side and the secondary wire 5B on the device side has the same shape and is formed by bending a metal plate having elasticity. As shown in FIG. 1, the crimp terminal 12 has electric wire crimping barrel portions 12a and 12b at one end thereof, while an electric contact portion 12c provided at the other end forms a side plate 12e, 12f by bending a substrate portion 12d. is doing. As shown in FIG. 3, the electrical contact portion 12c is inserted into the terminal accommodating chamber 11a, and the size of the base plate portion 12d and the side plates 12e and 12f is set to be close to the inner surface of the terminal accommodating chamber 11a. Is set.

Further, the crimp terminal 12 is provided with a contact portion 12g protruding outward at an upper end of a substantially central portion of one side plate 12e in the front-rear direction. The contact portion 12g is formed by horizontally bending a rectangular flat plate portion continuous with the upper end of the side plate 12e. Further, the contact portion 12g is provided with a contact 12h (shown in FIG. 3) which is formed by hitting the substantially central portion from above so as to project downward.

On the other side wall 12f as well, a rectangular flat plate portion is provided in a substantially central portion in the front-rear direction, and a slight cut is made in the side plate 12f from the protruding base portion to bend outward in the horizontal direction. The contact portion 12i is provided. The contact portion 12i and the contact portion 12g are in opposite positions, and the contact portion 12i is positioned below the contact portion 12g by approximately the plate thickness.

As shown in FIG. 3, the contact portion 12g and the contact portion 12i have the upper surface of the contact portion 12g set to a height along the inner surface of the upper wall 11h of the connector housing 11 and the contact portion 12g. The lower surface of 12i is set along the upper end surface of the partition wall 11d. That is, as shown in FIG. 4, the height of the slit provided between the upper end surface of the partition wall 11d of the connector housing 11 and the inner surface of the upper wall 11h is such that the contact portion 12g and the contact piece 12i overlap each other. It has a size that can be inserted with.

Further, in the crimp terminal 12, a locking hole 12j that engages with the lance portion 11g of the connector housing 11 is provided in the board portion 12d of the electric contact portion 12c.

Next, a process of assembling the joint connector 10 having the above structure will be described. First, the crimp terminal 12 connected to the electric wire 5A connected to the power source side is inserted into the terminal accommodating chamber 11a of the connector housing 11 through the slit 11b through the contact portion 12g and the contact portion 12i. The crimp terminal 12 is locked at a predetermined position by inserting the lance portion 11g into the locking hole 12j inside the terminal accommodating chamber 11a.

After that, the terminal 12 connected to the electric wire 5B connected to a device or the like is inserted into the adjacent terminal accommodating chamber 11a. The contact portion 12g and the contact portion 12i of the terminal 12 are also inserted through the slit 11b. When reaching the predetermined position, the contact portion 12g is located on the upper surface of the contact portion 12i of the adjacent terminal 12 which is already inserted, and the contact 12h protruding downward of the contact portion 12g is pressed against the contact portion 12i. Therefore, the electric wire 5B on the device side is connected to the electric wire 5A on the power supply side. At this position, the terminal 12 inserted later is locked by the lance 11g.

The embodiment of the present invention is not limited to the above-described configuration, and the contact portion and the contact portion formed on the terminal are configured so that adjacent terminals can contact each other through the slit formed in the connector housing. If it is good. In addition, if the terminal accommodating chambers are arranged in upper and lower two stages and the contact portions and the contact portions are formed so as to contact vertically adjacent terminals, a large number of separation circuits can be formed. Further, although the terminals to be mounted on the connector housing are crimp type terminals, they may be pressure contact type terminals.

[0024]

As is apparent from the above description, in the joint connector of the present invention, the connector housing is provided with the slit for communicating the terminal accommodating chamber, and the contact portion and the contact portion are projected from both sides of the terminal to both outsides. Therefore, the contact portion and the contact portion of the adjacent terminals can be brought into contact with each other by just inserting the terminals into the adjacent terminal accommodating chambers to generate conduction.

Therefore, the joint terminal and the cover housing, which have been conventionally required, are no longer required, the number of parts can be reduced, and the cost can be reduced. In addition, because the joint terminal and cover housing are not required, it is not necessary to consider the deformation of the joint terminal at the time of mounting, and it is not necessary to align the cover terminal with the groove of the cover housing. The work man-hour can be reduced, and the productivity can be improved.

Further, since the cover to which the short pin is attached is not attached to the connector housing, there are various advantages such as downsizing of the joint connector.
