Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a terminal device in which a female terminal fitting is mounted, which has an electrical contact part into which a male terminal is fitted at the front part, and a wire connection part at the rear part.

[Conventional technology]

This type of terminal device is described in Japanese Utility Model Publication No. 57-51508. FIG. 4 shows the terminal device. That is, an abutment wall 4 with which the rear ends of the electrical contact parts 9 of female terminal fittings 8 (hereinafter simply referred to as terminal fittings) abut against each other is provided at the rear inside of the terminal accommodating chamber 2, and an abutting wall 4 is provided inside the upper wall of the terminal accommodating chamber 2. A flexible locking arm 5 extending forward is provided, and a hook portion 14 that engages with the front end of the electrical contact portion 9 projects from the inside of the tip of the locking arm 5. The terminal fitting 8 can be inserted from the front opening end of the terminal accommodating chamber 2 by passing the electric wire 13 through the terminal housing chamber 2 in advance, fixing the terminal fitting 8 to the tip thereof, and pulling the electric wire 13 backward.

[Problem that the invention attempts to solve]

In the conventional terminal device as described above, after the electric wire 13 is passed through the terminal housing chamber in advance,
Since the terminal fitting 8 is fixed to the tip thereof, there is a problem in that it is difficult to perform the fixing operation.

This invention was made in order to solve such problems, and it is also an object of the present invention to provide a terminal device in which the work of fixing the electric wire and the terminal fitting can be easily performed without impairing the attachability of the terminal fitting.

[Means for solving problems]

In the terminal device according to this invention, the terminal fitting is provided with an engaging part and a locking part, and on the other hand, an opening is provided in the terminal accommodating chamber and the upper part of the wire insertion hole into which the electric wire to which the terminal fitting is connected can be dropped from above, Furthermore, a locking wall with which the locking part of the terminal fitting collides when the electric wire is pulled backward, an engaged part that engages with the engaging part of the terminal fitting, and a locking arm located on the top surface of the terminal fitting. It has been established that

[Effect]

In this invention, since the terminal accommodating chamber and the wire insertion hole are formed in a series of openings, it is possible to attach the terminal fitting and the electric wire to the terminal accommodating chamber after the terminal fitting and the electric wire are fixed in advance. Further, the locking wall, the engaging portion, and the locking arm of the terminal accommodating chamber restrict movement of the terminal fitting inserted into the terminal accommodating chamber in the front-rear and up-down directions.

〔Example〕

FIG. 1 is an exploded perspective view showing an embodiment of this invention, in which 8 is a conductive material provided with an electrical contact part 9 on the front part into which a male terminal (not shown) is fitted, and an electric wire connection part 10 on the rear part. The terminal fitting is formed of a metal terminal, and the intermediate part between the electrical contact part 9 and the wire connection part 10 is cut into the electrical contact part 9 side, and this cut part is bent downward to form a locking claw that becomes an engaging part. 12, and a locking portion 11 facing the wire connecting portion 10 and having a width wider than the width of the wire connecting portion 10. 13
is an electric wire fixed to the electric wire connection part 10.

On the other hand, 1 is a base formed of synthetic resin,
The base body 1 has a terminal accommodating chamber 2 for accommodating the terminal fitting 8 at the front thereof, and an electric wire insertion hole 3 communicating with the terminal accommodating chamber 2 at the rear thereof. These terminal accommodating chambers 2 and wire insertion holes 3 are connected to the terminal fittings 8.
and a series of openings 7 into which electric wires 13 can be inserted from above. In addition, the terminal housing chamber 2
A locking wall 4 that abuts the locking portion 11 of the terminal fitting 8 on the rear inner surface, and a bottom wall surface opposite to the locking wall 4 that serves as an engaged portion with which the locking pawl 12 engages. Two locking walls 6 and a locking arm 5 protruding from the side wall so as to be close to the upper surface of the terminal fitting 8 are provided. 16
A lid is attached to the base body 1 so as to close the opening 7, and has a protrusion 15 formed in the center thereof, which comes into contact with the upper surface of the terminal fitting 8 in the attached state.

Next, assembly will be explained.

The terminal fitting 8 and the electric wire 13 are separately fixed in advance. Next, the terminal fitting 8 to which the electric wire 13 is fixed is inserted together with the electric wire 13 from the opening 7 of the base 1 into the terminal accommodation chamber 2 and the electric wire insertion hole 3. fall into it. In this case, since the terminal fitting 8 is obstructed by the locking arm 5, a portion thereof protrudes forward from the terminal accommodating chamber 2.
Next, when the electric wire 13 is pulled backward, the locking part 11 of the terminal fitting 8 hits the locking wall 4 in the terminal housing chamber 2, and at the same time, the locking claw 12 hits the second locking wall 6. match. In this state, a portion of the upper surface of the terminal fitting 8 is covered by the locking arm 5, so that the terminal fitting 8 is prevented from advancing and retreating and is prevented from moving upwardly, and is thus fixed in position. Thereafter, the assembly is completed by attaching the lid 14 to the base 1 using attachment means such as screws (not shown).

In addition, in this invention, the following points can be arbitrarily selected.

(a) Number of terminal accommodating chambers and wire insertion holes; (b) Formation position and structure of the engaging portion of the terminal fitting and the engaged portion of the terminal accommodating chamber, that is, located on the flat surface or side portion of the terminal fitting; This includes everything that is convex on one side and concave on the other.

(c) Presence or absence of lid body.

[Effect of idea]

As explained above, this device has an engaging part and a locking part on the terminal fitting, and an opening in the terminal accommodating chamber and the upper part of the wire insertion hole into which the electric wire connected to the terminal fitting can be dropped from above. , a locking wall with which the locking part of the terminal fitting collides when the electric wire is pulled backward, an engaged part that engages with the engaging part of the terminal fitting, and a locking part located on the top surface of the terminal fitting. Since the arms are provided, the terminal fitting and the electric wire can be fixed in advance and inserted into the terminal accommodating chamber from above, and then the terminal fitting can be installed into the terminal accommodating chamber by pulling the electric wire backward. Therefore, there are advantages in that the attachability of the terminal fitting is improved and the terminal fitting and the electric wire can be easily fixed.
