Description

[Detailed description of the invention] <Industrial application field> This invention holds a large number of crimp terminals in parallel and feeds them sequentially between the crimping dies of a crimping machine, crimps the cylindrical portions of the crimp terminals, and The present invention relates to a band-shaped member for holding a group of crimp terminals used to crimply connect electric wires to a cylindrical portion.

<Prior Art> Conventionally, this type of band-shaped member for holding a group of crimp terminals has been disclosed, for example, in Japanese Utility Model Application Publication No. 59-41885.
It has been filed by the applicant and is publicly known. Although this means allows crimping to be performed using an automatic crimping machine and is extremely effective as a means for supplying crimp terminals to a crimping machine, it has been found that the following problems occur.

<Problems to be solved by the invention> That is, according to the above-mentioned conventional means, as shown in FIG. When inserting the cylindrical portion A1 into the cylindrical portion 01 of the strip member, the cylindrical portion 01 tends to tilt in the circumferential direction, so that the connecting portion A2 of the crimp terminal is parallel to the strip member and the cylindrical portion A1 There may be cases where the insertion position is not correct, with the joint A3 facing directly below. In this case, when crimping with the crimping die, the cylindrical part A of the terminal
1 is crimp-bonded in a state in which it is tilted to the right or left and irregularly deformed. If the connection between the crimp terminal and the electric wire is not made securely so that the electrical resistance is extremely low, it may cause heat generation, damage to surrounding equipment, or cause malfunction due to poor conduction. It's possible. On the other hand, the reliability of the product will be significantly reduced.

Therefore, the present invention has the advantage of the conventional strip member for holding crimp terminal groups in that it can be easily crimped automatically using an automatic crimping machine, but it also solves the drawbacks of the conventional product as described above. It is an object of the present invention to provide a band-shaped member for holding a group of crimp terminals, which allows wire connection terminals to be always in the correct crimp position.

<Means for solving the problem> The structure of the present invention to solve this problem will be explained with reference to FIGS. 1 to 3, which show examples of the structure of the present invention. The band-shaped member includes a large number of cylindrical parts 1... each having a thin wall part 1a which can be inserted into the cylindrical part A1 of the crimp terminal A having the joint part A3 and which can be separated at the upper part of the peripheral wall, and these cylindrical parts 1... In the belt-shaped member for holding a group of crimp terminals, which is configured by integrally forming a connecting plate 2 made of a synthetic resin material and connecting the connecting plates 2 parallel to each other at regular intervals, the crimp terminal group holding band member is configured such that the connecting plate 2 is connected in parallel with each other at regular intervals. The lower surface of the side that is substantially linear or consists of a pair of legs is formed into a parallel stabilization receiving portion 1b along the length direction of the band-like member.

<Function> As shown in FIG.
While pressing the cylinder portion 1 from above, the crimp terminal A is inserted and held in the direction of the arrow with its connecting portion A2 parallel to the transfer stage D. The strip member holding the terminal A in the correct posture in this way is wound up on a winding drum (not shown) of a required diameter, and transported to a factory or the like where the electric wire C is connected to the crimp terminal A by crimping. In a factory or the like, the cylindrical portion A1 of the crimp terminal A is inserted and held in each cylindrical portion 1 of the strip member formed in this way, and the crimping die B of the crimping machine is used.
The bare end C1 of the electric wire C is inserted into the cylindrical part A1 of the terminal A as shown in FIG. Connect wire C to terminal A by crimp.

<Embodiment> Figures 1 to 3 show an embodiment of the present invention, in which a number of cylindrical parts 1 for inserting and holding the cylindrical part A1 of the crimp terminal A, and each of these cylinders are shown. Part 1
Connecting plate 2 that connects ... in parallel at a certain interval...
are integrally formed from a synthetic resin material, and each cylindrical portion 1...
In the figure, there is a thin section 1a formed by forming a V-shaped groove 3 in cross section along the axial direction of the cylindrical section 1 in the upper center part.
... is formed, and the circumferential wall of the lower cylindrical portion 1 in the figure opposite to this thin wall portion 1a is made into a trapezoidal shape, and the receiving portion 1b on the lower surface is formed with the length of the strip member as shown in FIGS. 1 and 3. It is formed in parallel straight lines along the width direction. The shape of the peripheral wall of the cylindrical portion 1 below the connecting plate 2 may be square as shown by the chain line in FIG.

In addition, the shape of the receiving part 1b on the lower surface is such that, as shown in FIG. 4 and FIG.
It may be a shape having
Furthermore, as shown in FIG. 6, which is another embodiment, a structure may be adopted in which legs 1B, 1B protrude from both left and right sides of the peripheral wall. Further, as shown in FIGS. 7 and 8, the crimping die B1, An opening 4 may be formed for inserting the tip of the male mold B2. By doing this, the cylindrical portion A1 of the terminal A can be crimped with the crimping dies B1 and B.
2 can be directly crimped. Although the shape of the cylindrical portion 1 shown in FIGS. 7 and 8 was shown using the cylindrical portion 1 having the embodiment structure shown in FIG. It goes without saying that the structure of each embodiment illustrated in FIG. 6 may be implemented. 2a, 2 shown in Figures 3-5
a indicates the thick part of the connecting plate 2, and when the cylindrical part A1 of the terminal A is crimped, the downward protrusion formed on both sides of the female die B1 of the crimping dies B1 and B2,
It is formed so that it is easy to reliably cut the thin portion 1a by being pressed downward immediately before crimping.

As shown in Fig. 1, the strip member having the above structure is placed on a flat transfer table D, and while pressing the cylindrical part 1 from above, the cylindrical part A1 of the terminal is press-fitted from one side of the cylindrical part 1. do. At this time, since the lower surface side of the cylindrical portion 1 is linear or leg-shaped, the posture of the cylindrical portion 1 is always constant when the cylindrical portion 1 is pressed from above. Therefore, the terminal A can always maintain a constant posture with respect to the cylindrical portion 1, that is, the head A2 of the terminal A can be kept in a horizontal posture, and the joint portion A3 of the cylindrical portion A1 can be positioned at the lower center. Therefore, the crimping die B1,
The pressurizing posture by B2 can be made into a uniform pressurizing posture centering on the joint portion A3.

Although the embodiments have been described above, the shape for forming the thin wall portion 1a is not limited to a V-shaped cross section, but may be U-shaped or other shapes, and the inner circumferential surface side of the cylindrical portion 1 is not limited to the one in which the inner peripheral surface side of the cylindrical portion 1 is connected. They may be connected on the outer circumferential surface side or may be connected at the middle part of the thickness of the peripheral wall, as long as they have a shape that is easy to cut during the crimping operation by the crimping machine. Furthermore, the cylindrical portion 1 of the connecting plate 2
By forming the thick-walled portions 2a, 2a on both sides that are continuous with each other, it becomes easier to cut the thin-walled portion 1a, but the entire connecting plate 2 may be thick-walled, and it is not always necessary to cut the thin-walled portion 1a. It's not a thing.

<Effects of the Invention> As is clear from the above explanation, the present invention has two points in which the lower surface side of the cylindrical portion of the belt-shaped member facing the thin cutting portion is in a straight line and has fixing portions on both the left and right sides. By forming the support-like stability-maintaining receiving part 1B, it is now possible to easily and reliably keep the cylindrical part always in a constant posture when inserting the terminal into the cylindrical part. Therefore, it is possible to easily insert the cylindrical portion of the terminal in a constant angular position with respect to the cylindrical portion, and the crimping die can maintain a constant crimping position of the cylindrical portion of the terminal. In addition, since it is possible to apply uniform and appropriate pressure, it has become possible to obtain uniform electric wire connection terminals with peace of mind.
