Abstract

PURPOSE:To efficiently stop the back coming out of a connecting terminal even if the housing main frame is small by providing a movable side wall having locking projections and contacted to the connecting terminal at a part of the housing main frame. CONSTITUTION:A side wall of a terminal housing part 3 for housing a connecting terminal 2 of the housing main frame 1 is formed as a movable side wall 4c having the flexibility and a part of which in the long longitudinal direction is fixed and the other end is free. Fixed locking projections 6, 7 for preventing the back coming out of the connecting terminal 2 are provided at the inside of the movable side wall 4c and at the inside of the side wall 4a facing to the movable side wall 4c with the connecting terminal 2 between. A fixing member 8 for pressure-welding the movable side wall 4c to the connecting terminal 2 side after housing the connecting terminal 2 is inserted into the housing main frame 1 to be mounted. Thereby, the connecting terminal 2 can be securely locked at the side wall 4 of the housing main frame 1 without enlarging the shape of the housing 1.

Conventionally, a flexible locking piece called a case lance provided inside the housing has been used to prevent the housing from slipping out rearward. However, this case lance is not strong enough due to its narrow width, and its effectiveness in preventing it from slipping out is small. It may happen.

For example, it has been considered that the bottom surface of the connecting terminal on the opposite side of the case lance is locked by a fixed locking protrusion protruding from the housing. In order to get over the protrusion, the connecting terminal needs to be able to move freely within the terminal housing. However, in order to achieve this movable state, the internal volume of the terminal storage section in the housing must be increased to a certain extent, which poses a problem of adhesion between the housing and the contact t1 terminal, and furthermore, a large number of connection terminals are required. In a housing for accommodating the above, the shape of the housing itself has to be large, which is particularly unsuitable for a small-sized housing.

2 shows a state in which the housing body 1 will be housed from now on. The front end of the connection terminal 2 is a connection part 2a that fits into a mating male connection terminal, and the electric wire 2d is connected to it through a waterproof rubber seal 2C by crimping parts 2b and 2b' at the rear end. The terminal storage portion 3 of the housing body 1 is shaped to almost enclose the connection terminal 2, and the connection portion 2a is provided with side walls 4a, 4b, 4C14d on all sides, and the crimp portions 2b, 2b' at the rear end are provided with side walls 4a, 4b, 4C14d. In contrast, a side wall 5 having a circular cross section is provided. The upper side of the connecting terminal 2, that is, the lower side wall 4a of the upper connecting terminal 2, and the upper side wall 4a of the lower connecting terminal 2,
A movable side wall 4 is provided with a locking protrusion 6, and a side wall 4C on the opposite side via the connecting terminal 2 is provided with a second locking protrusion 7.
It is said to be c. The first locking protrusion 6 is for locking to a first locked portion 2e formed by cutting out a part of the connecting terminal 2. In order to make it easier for the connecting terminal 2 to cross over during insertion, the terminal insertion side is an inclined surface, and the opposite surface is raised at a right angle. Further, the movable side wall 4c is integrated with the housing main body 1 at its base portion on the terminal insertion side, and the distal end portion facing the front surface of the housing main body is a free end. The second locking protrusion 7 protrudes inside the intermediate portion of the movable side wall 4c in a shape substantially similar to that of the first locking protrusion 6. It is adapted to engage with a second locked portion 2f provided at the rear end of the connecting portion 2a. Further, as a separate member from the housing body 1, an annular fixing member 8 for press-contacting the movable side wall 4c to the connection terminal z side is attached to the housing body 1.
The fixing member 8, which is made of the same material as the housing body 1, is cocked into the housing body 1 by a locking mechanism (not shown).

When the connecting terminal 2 is further pushed in, it rides on the second locking protrusion 7 of the VC connecting portion 2a and is inserted into the interior, as shown in FIG. Further, by pushing the connecting terminal 2, the state shown in FIG. 4 is reached, and the state shown in FIG. 5 is reached, and the connecting terminal 2
The first IF part 2e to be tested engages with the first IF protrusion 6 of the housing body 1, and the second latched part 2f engages with the second IF protrusion 7 of the movable side wall 4C which has been restored by elasticity. will be engaged with. Then, by attaching the fixing member 8 to the housing body 1 from the front side, the movable side wall 4c is brought into pressure contact with the connection terminal 2. In this state, the connecting terminal 2 is fixed by the two locking protrusions 6.7, and there is no possibility of it accidentally slipping out rearward even under pressure from the mating male connecting terminal.

Furthermore, even if the insertion of the connecting terminal 2 into the housing body 1 is interrupted during work in the state shown in FIGS. 3 and 4, the movable side wall 4C does not move when the fixing member 8 is inserted, making it impossible to insert the fixing member 8. Therefore, it also has a function of detecting a mistake in the insertion operation of the connection terminal 2 into the housing body 1. Furthermore, if it becomes necessary to pull out the connecting terminal 2 from the housing body 1 for some reason, the fixing member 8 is unlocked and the fixing member 8 is removed.
By taking out the connecting terminal 2 and moving the movable side wall 4C from the front, it is possible to remove the connecting terminal 2 from the terminal storage hole 3 by reversing the insertion procedure.

In this embodiment, since part of the side wall of the terminal storage portion 3.13 is made into the movable side walls 4c, 14c, when the connecting terminals 2, 12 are inserted, these movable side walls 4C1
By moving 14c, it is possible to get over the first locking protrusion 6.16 in the housing body 1.11, and after the connection terminal 2.12 is inserted, the movable side walls 4c, 14c are fixed by the fixing members 8, 18. Since the connector housing is fixed, a very effective locking can be achieved, which is particularly suitable for small connector housings. Furthermore, if the second locking projections 7.17 of the movable side walls 4c, 14c, which correspond to conventional case lances, are widened to the same width as the movable side walls 4c, 14c,
The strength of the case lance, which has often been problematic due to its narrow width, is further improved.
