<Problems to be Solved by the Invention> By the way, there are the following problems in automating and implementing the conventional assembly method as described above.

() The only way to supply the holder in a fixed position and in a fixed posture is to use a parts feeder, and automation requires equipment costs for the parts feeder.

() Since the holder is extremely lightweight, the reliability of supply by the parts feeder is low.

() The use of parts feeders causes a decrease in operating rates, resulting in low productivity and increased costs.

<Purpose of the Invention> The present invention has been made to solve the above-mentioned problems, and provides a method for assembling a connector that can reduce equipment costs and assembly costs, as well as improve productivity. The purpose is to provide.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention divides a clip holder made of an electrically insulating material into two halves along a dividing plane along the connector axis, and also divides the clip holder into two pieces. It has a structure in which a clip for inserting a plug pin can be positioned and held from the dividing surface side, and the two-split holder is molded integrally with the bendable tape on both sides, and the tape is folded and attached to both sides. The divided surfaces of the holder are overlapped with the clip stored inside the holder, and a connecting case made of a conductive material is externally fitted and attached to the holder which has been separated from the tape and which is in a two-piece state.

<Function> Since the half-split holders are integrally molded with the tape on both sides of the tape, the two half-split holders can be overlapped by simply folding the tape, and the holder can be fed to a fixed position by hoop feeding together with the clip, making it easy to use the parts feeder. This eliminates the need for such special equipment, increases the reliability of fixed-position supply, and reduces assembly costs.

<Example> Hereinafter, an example of the present invention will be described based on FIG. 1 of the accompanying drawings.

Note that the same parts as in FIGS. 2 to 4 are designated by the same reference numerals and will not be described.

As shown in FIG. 1, the half-split holders 1a and 1b are located on both sides of the bendable tape 10.
It is outsert molded integrally with this tape 10.

As the tape 10, a paper tape made of a material such as NC tape is used, but it does not need to be a paper tape as long as it satisfies heat resistance and cost.

This tape 10 is provided with pitch holes 10a at regular intervals in the longitudinal direction in order to perform hoop feeding.
A center square hole 10b is provided at a central position along the longitudinal direction to facilitate folding the tape 10 in half.

The integral molding of both half-split holders 1a, 1b and the tape 10 is achieved by providing a connecting part 11 at the connecting end of the half-splitting holders 1a, 1b, and when insert-molding the tape 10, this connecting part 11 connects the tape 10 to both sides. In addition, it is preferable that the tape 10 be provided with a small diameter through which the resin of the connecting portion 11 penetrates, thereby increasing the bonding strength.

To assemble the connector, first tape 1
By supplying the half-split holders 1a, 1b integrally formed on the tape 10 and the clip 3 together on a reel, the tape 10 is
and hoop material 8 are continuously fed into the assembly line. By making the feeding pitches of the half-split holders 1a, 1b and the clip 3 the same, it is possible to easily align the two.

Next, at the combination position, the clip 3 is inserted into one of the half-split holders 1a, and the retaining tongue piece 3c is fitted into the retaining recess 7.

In this state, move the tape 10 to the center line B-
Fold it along B' and place the other half holder 1b over the one half holder 1a,
A clip 3 is stored between both half-split holders 1a and 1b.

Next, push the two halves of the holders 1a and 1b from both sides to sandwich the clip 3, cut the clip 3 from the band-like hoop material 8 at the cut line A, and cut the two halves of the holders 1a and 1b from the tape 10 to the connection part 1.
1 along the cut line C-C', insert the holder 1 into the connecting case 9, swage the thin part 9a of the case 9,
By integrating the holder 1c case 9,
A connector having the same cross-sectional structure as shown in FIG. 4 is completed.

In addition, in the above assembly explanation, the combination of the two half-split holders 1a and 1b was made so that one half-split holder 1a was bent 180 degrees to the other half-split holder 1b, but the clip 3 was positioned directly above the center of the tape 10. and both halves of the holder 1a
and 1b may be bent 90 degrees at the same time to perform the combination.

<Effects> As described above, according to the present invention, half-split holders are integrally molded on both sides of the bendable tape,
Since the two halves of the holder are combined by folding the tape, the holder can be fed along with the clip through the hoop, eliminating the need for special equipment such as a parts feeder, and reducing equipment costs.

Further, since the holder can be supplied to a fixed position by hoop supply, the reliability of supply is improved, the operating rate is increased, production capacity is increased, and assembly costs can be significantly reduced.
