うことができる。The female and male housings a and b are fitted to each other by initially fitting them and then sliding the pair of sliders c and c from the left and right ends of the female housing a toward the center, respectively. This is carried out by engaging the followers c 1 and c 1 with the cam tracks b 1 and b 2 and pulling the male housing b toward the female housing a. At this time, the slider c and the pin c 2 of the c are connected to the pin guide groove d of the rotary operation plate d.
When the rotary operation plate d is rotated in the forward and reverse directions by engaging with 1 and d 2 , the fitting and disengagement of both housings a and b can be performed with less force.

する。The conventional low insertion / removal force multipolar connector employing the cam mechanism requires a considerable work space above the connector in order to operate the slider c or the rotary operation plate d. Therefore, for example, when one male housing b is fixed to a narrow space such as an instrument panel (instrument panel) or a dashboard of an automobile, there is not enough working space, and therefore a cam that is effective for labor saving is provided. Even if a mechanism is adopted, it can hardly be used, and even if a working space is secured, it is difficult to work because the sliding direction of the slider and the rotating direction of the rotary operation plate are different from the fitting direction of the connector. There was a problem. The present invention has been made in view of such a problem, and by making the fitting direction and the operating direction of the connector the same, it is possible to easily perform the fitting / removing work of the connector even in a narrow space with a small force. An object of the present invention is to provide a low insertion / removal force multi-pole connector that enables

する。In order to achieve the above-mentioned object, the electric wire direction changing device of the present invention has a plurality of female and male terminals built-in and is fitted to each other so as to face each other. A pair of connector housings, and a cam block mounted on the outer wall of the one housing, the cam block being mounted on the outer wall of the one housing at an appropriate interval; The cam case includes a drive cam and a driven cam that are slidably mounted in the connector fitting direction and in a direction orthogonal to the connector fitting direction. The drive cam has a drive cam groove, and the driven cam engages with the drive cam groove. The driven housing has a driven cam groove together with a driven cam pin to be fitted, and the other housing has a driven cam pin that engages with the driven cam groove on the outer wall, and by sliding the driving cam in the connector fitting direction, Driven cam pin follower cam groove engaging the movement cam are attracted to the housing side of the one,
Thus, it is characterized in that both housings are fitted together.

とができる。When the drive cam is slid toward the other housing in a state where one connector housing is initially fitted to the other housing, the driven cam is engaged with the driven cam pin by the engagement of the drive cam groove and the driven cam pin. Moves perpendicular to the direction.
Therefore, by the driven cam pin that engages with the driven cam groove,
The other housing is pulled toward the one housing. That is, since the operation direction of the cam and the fitting (disengaging) direction of the connector are the same, a wide working space as in the past is not required, and the work is facilitated. In addition, the combination of the two cam plates enables the fitting and disengagement with a smaller force.

保される。As shown in FIG. 3, the drive cam 19 is connected to the arrow P '.
When it is pulled back in the direction, the driven cam 22 moves to the arrow Q'due to the engagement of the driven cam pin 24 and the drive cam groove 20. As a result, the flexible lock piece 16 enters the lock groove 26 of the driven cam 22, and the protrusion 16a engages with the lock hole 26a and is provisionally locked (initial insertion position). The cam pin introduction groove 10 on the front wall 10c of the cam case 10 is provided.
d is aligned with the inlet portion 25a of the driven cam groove 25 of the driven cam 22. Temporary locking and unlocking can be easily done by sliding the drive cam 19. Therefore, when the cam block D is assembled and stored, it is fully inserted into the slide groove 13 and the projection 21 on the rear surface of the rear end portion is locked. The pin guide hole 14 is engaged and locked through the groove 15. As shown in FIG. 1, the assembly of the cam block D is fixed by screwing it through the screw insertion hole 17a of the guide boss 17 and the screw insertion hole 17a 'of the side wall 10b through the screw 29 to the back surface of the male connector B. To be done. Since the front wall 10c of the cam case 10 is lower than the other three side walls as described above, the entry space V for the female connector C is secured between the front wall 10c and the male connector B.

Is fitted shallowly and temporarily locked. That is, when the male connector B is inserted into the hood 7 of the female connector C using the approach space V on the front surface of the cam block D, the driven pin 8 enters the driven cam groove 25 through the cam introducing groove 10c. The hood 7 enters the inside of the portion 25a and stops there, and the hood 7 is seated on the receiving seat 11 (see FIG. 2). At that time, the locking projection 9 of the female connector C pushes down the flexible lock pieces 12 on both sides of the cam case 10 to get over the projection 12b by the taper 12a and reach the back thereof, and the elastic lock piece 12 elastically returns. Both connectors B and C are temporarily locked by this.

The driven cam 22 slides in the direction of arrow Q by the driven pin 24 engaging with 0, and the inclined portion 25 of the driven cam groove 25.
The female connector C is pulled to the male connector B side by the driven pin 8 engaging with b. When the driven pin 24 reaches the end of the drive cam groove 20, the connectors B and C are completely fitted. At the same time, the drive cam 19 is locked by the locking projection 21 engaging with the pin guide groove 14 via the lock groove 15. The disengagement of the connectors B and C can be easily performed by the action opposite to the above, if the drive cam 19 is pulled back as shown by the arrow P '.

小さい力で難なく着脱を行うことができる。As described above, since the operating direction of the drive cam 19 coincides with the mating and uncoupling directions of the male connector B and the female connector C, it is easy to do without a wide working space around the connector. You can do the work. Further, since a large force multiplication factor can be obtained by combining the two driving cams 19 and driven cams 22 that slide at right angles, even if the number of poles (number of female and male terminals) of the connector increases, the operator It can be attached and detached with less force without difficulty.

きる。As described above, in the low insertion / removal force multi-pole connector of the present invention, the operating direction of the cam (driving cam) and the fitting direction of the connector are matched by the combination of the driving cam and the driven cam. Therefore, it does not require a large working space and can be easily used even in a narrow space such as an instrument panel. Furthermore, the combination of the drive cam and the driven cam allows the connector to be fitted and removed with less force. .

多極コネクタ。1. A pair of connector housings, each of which has a plurality of female and male terminals built therein and which are fitted to each other, and a cam block mounted on an outer wall of one of the housings. A cam case that is attached to the outer wall of one of the housings at an appropriate interval, and a drive cam and a driven cam that are slidably mounted on the cam case in the connector fitting direction and the direction orthogonal to the connector fitting direction, respectively. The drive cam has a drive cam groove, the driven cam has a driven cam pin together with a driven cam pin that engages with the drive cam groove, and the other housing has an outer wall with a driven cam pin that engages with the driven cam groove. By sliding the driving cam in the connector fitting direction, the driven cam pin that engages with the driven cam groove of the driven cam is pulled toward the one housing side, and thus A low insertion / removal force multi-pole connector characterized by a structure in which the plug is fitted.
