Description

The present invention relates to a connector having a terminal fitting provided with a protrusion.

Some terminal fittings have a protruding stabilizer (protrusion). If the terminal fitting is inserted into the housing in the wrong orientation, the stabilizer will hit the housing, making it impossible to insert the terminal fitting. However, when a stabilizer is provided on a terminal fitting, a problem arises in that when inserting the terminal fitting into a housing, the lance has to overcome the stabilizer with a large protrusion, which increases the insertion force of the terminal.

Therefore, a connector described in Patent Document 1 has been proposed. In the connector described in Patent Document 1, the stabilizer passes on both sides of the lance when the terminal fitting is inserted, so that the lance does not need to climb over the stabilizer. However, according to the connector of Patent Document 1, the locking force is weak because the lance cannot lock the stabilizer.

The protruding portion is provided to protrude from the rear end of the box portion in the insertion direction,
the locking piece locks both the box portion and the protrusion portion;
Must be a connector.

According to the connectors having the configurations [1] and [2] above, the pressing portion provided on the front holder presses the locking piece toward the protrusion in the second deflection direction, thereby moving the locking piece toward the protrusion. It is locked on the rear end side in the insertion direction. Thereby, when inserting the terminal fitting, the locking piece does not come into contact with the protrusion, so that the insertion force of the terminal fitting can be reduced. When the front holder is accommodated in the housing, the locking piece locks the rear end side of the protrusion in the insertion direction, thereby improving the locking force.

According to the connector having the configuration [3] above, the inclined surface can guide the locking piece from bending toward the protrusion.

According to the connector having the configuration [4] above, the tip of the box portion of the terminal fitting deforms the locking piece in the first deflection direction. When the terminal fitting is housed in the terminal accommodating chamber, the locking piece locks the box portion. Thereafter, when the front holder is housed in the housing, the locking piece moves toward the protrusion in the second deflection direction and also locks the deflection protrusion. Thereby, the locking piece locks both the box portion and the protruding portion, thereby improving the holding force of the terminal fitting.

According to the present invention, it is possible to provide a connector in which the insertion force of a terminal fitting is reduced.

Ru. Further, at the tip of the housing 3, the terminal fitting 2 accommodated in the lower terminal accommodating chamber 301 is sandwiched between the front partition wall 45 and the bottom wall 41, and is positioned in the vertical direction D3. That is, a space surrounded by the ceiling wall 43, front partition wall 45, and bottom wall 41 of the front holder 4, and the first vertical wall 314 and second vertical wall 315 of the housing 3 becomes the terminal accommodating chamber 301 at the tip of the housing 3.

The bottom wall 41 and the front partition wall 45 are provided longer in the insertion direction D1 than the pair of front side walls 42 and the ceiling wall 43, and are provided so as to protrude further toward the rear end side in the insertion direction D1 than the front side walls 42 and the ceiling wall 43. . Further, the rear end sides of the bottom wall 41 and the front side wall 42 are provided with a notch 47 (FIG. 6) provided for each terminal accommodating chamber 301, which fits into the positioning convex portion 312 provided on the housing 3 described above. Further, the ceiling wall 43 and the front partition wall 45 are provided with a lance pressing part 48 and a lance pressing part 49 (pressing part), as shown in FIG. 13 and the like. The lance pressing part 48 and the lance pressing part 49 are provided for each terminal accommodating chamber 301. The lance pressing portion 48 presses the lance 302 downward. As shown in FIG. 11, the lance pressing portion 49 presses the lance 302 toward one side in the width direction (the side of the stabilizer 24) to bend it.

As shown in FIG. 13, the lance pressing part 48 provided on the ceiling wall 43 projects from the rear end surface of the ceiling wall 43. Further, the front partition wall 45 is thicker on the front end side than on the rear end side of the rear end surface of the ceiling wall 43, and is provided with a stepped surface. A lance pressing portion 48 provided on the front partition wall 45 projects from this stepped surface toward the rear end.

The lance pressing portion 49 projects downward from the ceiling wall 43 and the front partition wall 45. The lance pressing part 49 is provided in a plate shape orthogonal to the width direction D2, and is provided on the other side of the lance pressing part 48 in the width direction D2. The lance pressing part 48 is provided so as to protrude further toward the rear end than the lance pressing part 49.

As shown in FIG. 2, the front side wall 42 is provided with a temporary locking portion 42a and a permanent locking portion 42b. When the temporary locking portion 42a locks with the housing 3, the front holder 4 temporarily locks the housing 3 at the temporary locking position where the tip protrudes from the housing 3, as shown in FIGS. 3 and 4. be able to. In the temporary locking position, as shown in FIG. 9, the lance pressing portion 48 does not press down the lance 302. Further, in the temporary locking position, the lance pressing portion 49 does not bend the lance 302 in the width direction D2. When the main locking part 42b locks with the housing 3, the front holder 4 can fully lock the housing 3 at the main locking position where the front holder 4 is accommodated in the housing 3 up to the tip, as shown in FIG. Can be done. In the main locking position, the lance pusher portion 48 pushes down the lance 302. Further, at the final locking position, as shown in FIG. 11, the lance pressing portion 49 bends the lance 302 toward the stabilizer 24 in the width direction D2.

Next, assembly of the connector 1 having the above-described configuration will be explained. First, the front holder 4 is inserted into the housing 3 from the tip side. A temporary locking portion 42a provided on the front holder 4 locks on the housing 3, and the front holder 4 is temporarily locked. As shown in FIG. 3, in the temporary locking position, the lance pressing part 48 is located on the distal side of the lance 302 and does not press down on the lance 302. Further, the upper surface of the bottom wall 41 of the front holder 4 and the upper surface of the rear end portion of the bottom wall 303 of the housing 3 are arranged on substantially the same plane. The upper surface of the front partition wall 45 of the front holder 4 and the upper surface of the first housing partition wall 309 of the housing 3 are also arranged on substantially the same plane.

Thereafter, as shown in FIG. 3, the terminal fitting 2 is inserted from the rear end of the housing 3. At this time, the terminal fitting 2 is inserted into the housing 3 with the stabilizer 24 erected upward. The upper part of the stabilizer 24 is inserted into the groove 311. When the terminal fitting 2 is further inserted toward the distal end side, the distal end of the terminal fitting 2 comes into contact with the lower surface formed on the inclined surface of the lance 302, as shown in FIG. When the terminal fitting 2 is further inserted, the lance 302 is bent upward by the terminal fitting 2.

Further, when the lance 302 is not bent in the width direction D2, the stabilizer 24 and the lance 302 do not face each other in the insertion direction D1. Therefore, the stabilizer 24 can be inserted to the distal end side of the lance 302, as shown in FIGS. 8 and 9, without hitting the lance 302. When the stabilizer 24 is located on the distal side of the lance 302, that is, when the box portion 21 is located on the distal side of the lance 302, the lance 302 is restored downward and the rear end of the box portion 21 is moved as shown in FIG. to lock. At this time, the lance 302 does not engage the rear end of the stabilizer 24, as shown in FIGS. 8 and 9.

Thereafter, when the front holder 4 is pushed toward the rear end side, the lance pressing portion 49 comes into contact with the side surface S1 of the lance 302 on which the inclined surface is formed. When the front holder 4 is further inserted, the lance 302 is bent toward one side in the width direction D2 (towards the stabilizer 24) by the lance pressing portion 49, as shown in FIG. Due to the inclined surface provided on the side surface S1, the lance 302 is bent toward the stabilizer 24 as the front holder 4 is inserted toward the rear end. Further, when the front holder 4 is inserted toward the rear end side, the main locking portion 42b is locked to the housing 3. At this time, the lance pressing part 48 of the front holder 4 is located above the rear end of the lance 302, and as shown in FIG. 5, the lance 302 is pushed down. Thereby, the locking force of the terminal fitting 2 by the lance 302 can be further improved. Further, at the main locking position, as shown in FIGS. 10 and 11, the lance 302 locks the rear end sides of both the box portion 21 and the stabilizer 24. Thereby, the locking force of the terminal fitting 2 by the lance 302 can be further improved. Further, the guide wall 46 comes into contact with the tip of the terminal fitting 2 and locks the terminal fitting 2. Further, the positioning projection 312 of the housing 3 fits into a notch 47 provided at the rear end of the bottom wall 41 and the front partition wall 45 .

According to the embodiment described above, the lance pressing part 49 provided on the front holder 4 presses the lance 302 toward the stabilizer 24 in the width direction D2, and moves the lance 302 toward the rear end side of the stabilizer 24 in the insertion direction D1. Lock it. Thereby, when the terminal fitting 2 is inserted, the lance 302 is prevented from hitting the stabilizer 24, so that the insertion force of the terminal fitting 2 can be reduced. When the front holder 4 is accommodated in the housing 3, the lance 302 locks the rear end side of the stabilizer 24 in the insertion direction D1, thereby improving locking force.

According to the embodiment described above, by providing the inclined surface on the side surface S1 of the lance 302, it is possible to guide the lance 302 from bending toward the stabilizer 24 side.

According to the embodiment described above, the tip of the box portion 21 of the terminal fitting 2 deforms the lance 302 downward. When the terminal fitting 2 is accommodated in the terminal housing chamber 301, the lance 302 locks the box portion 21. Thereafter, when the front holder 4 is housed in the housing 3, the lance 302 is bent toward the stabilizer 24 side in the width direction D2, and the stabilizer 24 is also locked. Thereby, the lance 302 locks both the box portion 21 and the stabilizer 24, so that the holding force of the terminal fitting 2 can be improved.

Note that the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

According to the embodiment described above, the side surface S1 of the lance 302 on the lance pressing part 49 side is provided with an inclined surface that approaches the stabilizer 24 toward the tip in the insertion direction D1, but the present invention is not limited to this. The sloped surface may be provided on the side surface of the lance pressing section 49 on the lance 302 side, or the sloped surface may be provided on the side surfaces of both the lance 302 and the lance pressing section 49.
