Abstract

(57) [Abstract] [Purpose] To provide a connector in which an electrical connection state can be reliably obtained even when the insertion force is reduced. [Structure] The locking projection 3a of the lance 3 of the connector housing 1 is inserted into the locking window 2a of the bottom surface of the terminal 2 to lock the terminal 2 in the connector housing 1. A tongue piece 2b is attached to the terminal 2 from the tip of the bottom surface of the terminal 2 into the mating terminal insertion hole 2 of the terminal 2.
It is arranged in a folded shape in c. The terminal 2 has a locking window 2
An auxiliary tongue 2d is provided adjacent to a. The terminal 2 is double-locked in the lance escape space 4 between the lance 3 and the inner surface of the connector housing 1, and the terminal 2 is pushed up via the lance 3, and the locking projection 3a of the lance 3 assists the auxiliary tongue. The terminal double locking / terminal pushing up piece 6 for pressing the tongue piece 2b against the mating terminal 5 via the piece 2d is inserted. On the upper surface of the rear portion of the terminal double locking / terminal pushing up piece 6, a tapered surface 6a is provided whose height gradually increases toward the rear portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to, for example, a connector used for connecting electrical wiring materials for automobiles and the like.

[0002]

[Prior Art]

 In the conventional connector of this type, the terminal accommodated in the connector housing is locked by the lance of the connector housing. In addition, a double terminal locking piece is inserted in the lance clearance gap between the lance and the inner surface of the connector housing. When the terminal double locking piece is inserted into the lance escape space as described above, it is possible to determine whether the terminal is correctly locked to the lance or not depending on whether the terminal double locking piece can be inserted. Further, by leaving the terminal double locking engagement piece inserted in the lance escape space, the escape of the lance can be prevented, and the terminal can be prevented from dropping from the connector housing.

In this case, the terminal double-locking piece is not intended to ensure the contact between the terminal and the mating terminal, and the tip of the terminal double-locking piece should be used only to confirm the lifting and lowering of the lance. The thickness of the tip of the terminal double locking piece was set to a value as close as possible to the height of the lance relief gap.

[0004]

[Problems to be solved by the device]

 In such a connector, the mating terminal insertion hole of the terminal is set to be narrow so that the electrical connection state is surely obtained when the mating terminal is inserted into the terminal. Therefore, in a multi-pole connector, the total insertion force when inserting the mating multi-pole connector is due to the stacking of the insertion force for each terminal. was there. An object of the present invention is to provide a connector that can reliably obtain an electrical connection state even when the insertion force is small.

[0005]

[Means for Solving the Problems]

 To explain the structure of the present invention which achieves the above object, the present invention relates to a connector in which a terminal housed in a connector housing is locked by a lance of the connector housing. Into the lance escape space between the inner surface and the inner surface, a terminal double-locking and terminal pushing-up piece is inserted, which double-locks the terminal and pushes up the terminal and presses a part of it against the other terminal. It is characterized by

[0006]

[Action]

 By using the terminal double locking / terminal pushing up piece in this way, the mating terminal insertion hole provided in the terminal can be made larger than before. For this reason, the mating terminal can be inserted into the terminal with a small insertion force, and even with a multi-pole structure, the mating connector can be connected with a smaller insertion force than before.

Further, when the mating terminal is inserted, when the terminal double locking and terminal pushing up piece is inserted into the lance escape space, the terminal is pushed up by the terminal double locking and terminal pushing up piece and a part thereof is inserted. Is pressed against the mating terminal, and the electrical connection between the terminal and the mating terminal is ensured.

【Example】

 1 and 2 show an embodiment of a connector according to the present invention. In the connector of the present embodiment, the terminal 2 is housed in the connector housing 1, and the terminal 2 has the locking projection 3a of the lance 3 of the connector housing 1 inserted into the locking window 2a of the bottom surface of the terminal 2. It is locked to the connector housing 1. A tongue piece 2b is arranged in a folded shape from the tip of the bottom surface of the terminal 2 into a mating terminal insertion hole 2c. Further, the terminal 2 is provided with an auxiliary tongue piece 2d adjacent to the locking window 2a.

A lance escape space 4 is provided between the lance 3 and the inner surface of the connector housing 1. The terminal 2 is double-locked in the lance escape space 4 and the terminal 2 is pushed up via the lance 3, and the locking projection 3a of the lance 3 pushes the tongue 2b via the auxiliary tongue 2d. A terminal double-locking / terminal pushing-up piece 6 for press-contacting the terminal 5 with the mating terminal 5 is inserted. For this reason, the rear surface of the terminal double locking / terminal pushing up piece 6 is provided with a tapered surface 6a whose height gradually increases toward the rear portion.

When such a terminal double locking and terminal pushing up piece 6 is used, the mating terminal insertion hole 2c provided in the terminal 2 can be made relatively larger than the conventional one. Therefore, the partner terminal 5 can be inserted into the terminal 2 with a small insertion force, and even if the connector has a multi-pole structure, the mating connector can be connected with a smaller insertion force than before.

Further, when the mating terminal 5 is inserted, when the terminal double locking / terminal pushing up piece 6 is inserted into the lance escape space 4, the terminal 2 is double locked and as shown in FIG. , The auxiliary tongue 2d of the terminal 2 is pushed up by the terminal double locking piece / terminal pushing up piece 6 via the locking projection 3a of the lance 3, and the tongue 2b is pushed up by the rising of the auxiliary tongue 2d. Then, the tongue piece 2b is pressed against the mating terminal 5. Therefore, the electrical connection between the terminal 2 and the mating terminal 5 can be surely made.

[0012]

[Effect of the device]

 As described above, the connector according to the present invention uses the terminal double-locking and terminal-pushing piece that double-locks the terminal and pushes up the terminal to press a part of the terminal against the mating terminal. Therefore, the mating terminal insertion hole provided in the terminal can be made relatively larger than before. Therefore, the mating terminal can be inserted into the terminal with a small insertion force, and even if the multi-pole structure is used, the mating connector can be connected with a smaller insertion force than before.

When the mating terminal is inserted, by inserting the terminal double locking / terminal pushing up piece into the lance escape space, the terminal is pushed up by the terminal double locking / terminal pushing up piece. A part of it is pressed against the mating terminal, and the electrical connection between the terminal and the mating terminal can be reliably obtained.
