FIG. 1 is a developed view of the contact terminal member 11 for a connector of the present invention after punching, FIG. 2 is a perspective view of the contact terminal member 11 for a connector of the present invention after bending, and FIG. 3 is a contact terminal member for a connector of the present invention. 11 is a perspective view showing a state of being wound and stored on a reel, and FIG. 4 is a sectional view taken along the line BB of FIG.

As is apparent from FIGS. 1 to 4, the contact terminal member 11 for a connector according to the present invention has substantially the same structure and operation and effects as those of the members other than the terminal deformation preventing piece 17. That is,
A connector according to the present invention comprising an electrical contact portion 15 at one end where a connector pin can be inserted via a contact surface 16 and a connector contact terminal 12 having a clamping portion 14 at the other end of which a wire harness can be crimped and fixed. The contact terminal member 11 for the whole is made of, for example, a flat plate of phosphor bronze, and a large number of connector contact terminals 12 are formed at a predetermined pitch P in a desired developed shape with respect to a carrier portion 13 which is continuous in a narrow band. After being punched out once, the protruding pieces 14a, 14b, 14c, 14d, 15a, 15b projecting from both sides of the holding portion 14 and the contact portion 15 are bent at substantially right angles, and thereafter, FIG. As shown in FIG.
The reel 7 is provided to the user in a state of being wound and stored in a coil shape on the outer peripheral surface of a hub (not shown).

However, as shown in FIG. 4, the contact terminal member 11 for a connector of the present invention wound on the reel 7 is provided on each of the projecting pieces 14a to 14d, 15a, 15b which are bent at substantially right angles. The other protruding pieces 14a to 14d, 15a, and 15b of the outer circumference are pressed and wound, and the bent portion or the carrier portion of each of the protruding pieces 14a to 14d, 15a, and 15b depending on the weight or winding tension of the connector contact terminal member 11. The connection part of 13 is deformed, the deformation failure is not detected in advance and the user side crimps the wire harness,
In order to prevent the fixing or bending of the contact portion 15 to prevent the occurrence of many defective products, a terminal deformation preventing piece 17 is provided, which is a feature that is significantly different from the conventional contact terminal member 1 for a connector. .

The terminal deformation preventing piece 17 according to the present invention is provided on both sides of the holding portion 14 and the contact portion 15 and has a bending height a or more of each of the protruding pieces 14a to 14d, 15a, 15b which are bent at substantially right angles. It is bent at a substantially right angle with a bending height b,
In addition, since the connector is protruded at a pitch P substantially equal to that of the connector contact terminal 12 via the connecting portion 18 extending from the carrier portion 13 to the connector contact terminal 12, the terminal deformation preventing piece is provided.
16 each other protruding pieces 14a to 14d, 15a, 15
b is directly supported to prevent the upper and lower projecting pieces 14a to 14d, 15a, 15b from coming into contact with each other.

The terminal deformation preventing piece 17 is provided with the connector contact terminal 12 when the connector contact terminal member 11 is unfolded.
Since the protrusions 14a to 41d, 15a and 15b are provided in the dead space between the carrier 13 and the protrusions 14a to 41d, 15a and 15b, there is no waste of material. Accordingly, the connector contact terminal member 11 wound and stored on the reel 7 has its protruding pieces 14a to 14d, 15a, and 15b conducted by external force such as the weight of the connector contact terminal member 11 and the winding tension. It prevents sexually harmful deformation and can be safely stored for a long time in a wound state. In the above-described embodiment, the female terminal in which the contact pin is inserted into the contact surface 16 of the electric contact portion 15 has been described.
Even if it is a contact pin shaped terminal as shown in
It has a similar function.

[0015]

The contact terminal member for a connector of the present invention configured as described above has the following novel effects. That is, the connector contact terminal member 11 of the present invention
The connector pin can be inserted through the contact surface 16 at one end where it has been punched once so as to couple a large number with a desired development shape at a predetermined pitch to the carrier part 13 that is continuous in a narrow band shape. The electrical contact portion 14, the other end is provided with a connector contact terminal 12 having a clamping portion 15 capable of crimping and fixing the wire harness, and furthermore, protrudingly provided on both sides of the clamping portion 15 and the electric contact portion 14. Each of the protruding pieces 14a to 14d, 15a, and 15b that are bent at a substantially right angle has a bending height b that is equal to or greater than the bending height a, and protrudes from the carrier 13 at a pitch P substantially equal to that of the connector contact terminal member 11. Since the terminal deformation preventing piece 17 is provided, the terminal deformation preventing piece 17 directly supports the other projecting pieces 14a to 14d, 15a, 15b wound around the outer periphery thereof, and the upper and lower projecting pieces 14a. ~ 14d, 15a, 15b should be kept at a good distance from each other It allows, while preventing excessive contact, also became possible to safely stored for a long period of time in a state wound.

The terminal deformation preventing piece 17 is provided in a relatively narrow space between the connector contact terminals 12 at a projecting pitch P substantially equal to the projecting pitch P of the connector contact terminal member 11 with respect to the carrier portion 13. Since they are provided, the amount of the flat plate material used does not increase more than before, and the punching and bending processes are not particularly complicated, so that an increase in production cost can be suppressed.
