Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an improvement of a female terminal connector used in automotive wire harnesses and the like.

[Prior art and its problems]

For example, a connector as shown in FIG. 3 is used in automotive wire harnesses. In the figure, 11 is a female terminal connector, and 12 is a male terminal connector. The female terminal connector 11 is composed of a female terminal 13 and a plug housing, and the male terminal connector 1
2 is composed of a male terminal 15 and a cap housing 16. A lance 17 for preventing the female terminal from coming off is formed inside the plug housing 14, and a lance 18 for preventing the male terminal from coming off is formed inside the cap housing 16. 19 is female terminal 1
3 is an electric wire connected to it, and 20 is an electric wire connected to a male terminal.

By the way, in the connector configured as described above, when the female terminal connector 11 and the male terminal connector 1 are inserted and connected, the tab of the male terminal 15 may become loose as shown in the figure due to looseness of the male terminal 15 within the cap housing 16. The portion 21 may come into contact with the front edge of the female terminal 13. If the insertion is continued in this state, the lance 17 on the female terminal 13 side or the lance 18 on the male terminal 15 side will be damaged, and the female terminal 13 or male terminal 15 will come out of the housing 14 or 16, resulting in a poor connection. do.

Furthermore, as recent connectors have become smaller and lighter, the internal dimensions of the housing have become extremely small, which has resulted in smaller lances for preventing the terminals from coming off, and the strength with which the terminals are retained. As a result, for example, if a tensile force is applied to the wire connected to the terminal, the terminal will come off the lance, and
There is also the problem of them falling out of the housing.

[Means for solving problems and their effects]

The present invention provides an improved female terminal connector in order to solve the problems of the prior art as described above, and its structure is such that the female terminal is housed in a housing that has a lance for preventing the female terminal from falling out. In the female terminal connector, a peg is inserted from the front end side of the housing between the fitting portion of the female terminal and the wall of the housing having the lance, and the peg is inserted into the housing so that the male terminal is inserted into the female terminal connector. a guide portion that guides the female terminal so as not to come into contact with the front edge of the lance side;
It is characterized by having a lance suppressing part that suppresses the movement of the lance, and a retaining part from the housing.

According to the above configuration, the male terminal is guided by the guide part of the peg and inserted into the proper position of the female terminal, and the movement of the lance for preventing the female terminal from coming off is suppressed by the lance restraining part of the peg. For,
The locking strength of the female terminal is improved.

〔Example〕

1 and 2 show a female terminal connector according to an embodiment of the present invention. The configurations of the female terminal 13 and the housing 14 are the same as those of the conventional one. In this connector 11, a peg 24 is inserted from the front end side of the housing 14 between the fitting part 22 of the female terminal 13 and the wall 23 of the housing 14 that has the lance 17. This peg 24 has a guide portion 25 that guides the male terminal so that the male terminal does not come into contact with the front edge of the female terminal 13 on the lance 17 side, and a lance restraining portion 26 that suppresses the movement of the lance 17. There is. The lance suppressing part 26 is formed by a tongue piece 26a inserted into a gap on the lower side of the lance 17 and a protrusion piece 26b that engages with the upper side of the distal end of the lance 17.
is blocking the movement of Further, the peg 24 is configured such that a locking protrusion 27 formed on the side surface of the peg 24 engages with a locking hole 28 of the housing 14 so that the peg 24 does not slip out of the housing 14.

Although the above embodiment shows a two-pole connector, the number of connector poles is not particularly limited.

[Effect of idea]

As explained above, according to the present invention, the peg is inserted into the front end side of the housing and the peg has a male terminal guide portion, so that the male terminal does not come into contact with the front edge of the female terminal. Connectors can be connected to each other smoothly. Further, since the lance for preventing the female terminal from coming off is prevented from moving by the lance restraining portion of the peg, there is an advantage that the locking strength of the female terminal is improved.
