Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to, for example, a crimp-type terminal molded body for connection with a C1 connector terminal or the like.

(b) J Bunso's background object and 8th/12th/lj: The molded body is made from a band-shaped hoop made of a thin spring plate such as phosphor bronze, which is then punched with a press die. It has high dimensional accuracy and is connected to each other. Since the reliability of the electrical connection is important for the single-shaft molded product, the band-shaped hoop material is subjected to tin-lead plating or native plating prior to the molding.
A spring material with a U length of +1 and a thin spring plate with as high conductivity as possible is selected.

Processing is extremely easy.

(e) Prior Art and Problems FIGS. 1 and 2 show an example in which a conventionally molded strip and groove are molded into a band-like hoop member.

In FIG. 1, (a) is a perspective view of a molded terminal body connected to an N-body terminal of a connector. In the figure, 1 is the absolute Pt, the broken wire, 2 is the connector terminal connection 1 (1) is the contact that will become Shirotana, te, connector, l, 7"j ((b)
There is provided an inwardly projecting projection 3 which is inserted into the connector (see Isi 7) and obtains a stable connection with spring pressure behind it. Reference numerals 4 and 5 are parts that grip the outer periphery of the terminal body in the form of a thin plate. Molded with 2, 4 and 5Vt integrated spring bodies.

In addition, (b) of FIG. 1 shows that (a) the figure chanter molded body is 1'4
・This is a simplified front view of the terminal part of the housing on the connector side that will be inserted.

In the figure, 6Irt insulating floor body, and 7 are connector terminals, each of which has a rectangular cross section. A terminal body for wire crimping as shown in the figure (a) is inserted from the front side of the connector terminal 7, so that the wire can be easily connected to the connector.

Incidentally, this is carried out using a jig for melting the wire (conductor) and the terminal body in the pressing connection section 4.

FIG. 2 is a front view of the end preformed band hoop member formed as described above.

Comparing Figure 1142 with Figure 1 (A) shows the molded contact 2. Wire crimp connections 4, insulation gripping parts 5, etc. are continuously molded into the band-like hoop, and in the contact portion, the inner side 1.
Front view of U-shaped JK formed by bending a 1/19th corner (a)
It is clear that 2) in the figure has taken place.

In the figure, reference numeral 8 denotes a crosspiece of a tube member that horizontally connects 15 hand-molded bodies at each shop, and 9J/f! This is also the same as 8, with the rest being 9
A feed hole 10 is provided on the side for feeding the hoop portion U4 pitch. Thus, when the molded body 11 in the illustrated state is completed with the required processing, the upper and lower ends are chained at one point 1fJ9-A'
, Cut at the position B-B' to complete production of individual pieces.

At this time, the contact portion 2 is bent to a predetermined precision and deformed, causing a failure in fitting the terminal 7 into place.

For this reason, if the upper crosspiece 8 is burnt and the bottom crosspiece 11 is supported by the lower crosspiece, when the hoop molding 1'4- is conveyed, the molded body will move back and forth or on the right side. , it is biased towards Ti, which hinders hoop processing, and in extreme cases, B-B
It may break near the connecting point of #.

(d) Object of the invention The object of the invention is to solve the above-mentioned problems. That is, the supporting strength of the connection point of the hoop member in the terminal molded body 11 is impaired.

(e) Structure of the Invention In order to achieve the above object, the present invention provides the following features:
lm[: The problem of υ was solved by forming a convex or concave cross-section irregularly connected part in the connecting part.

(f) Embodiments of the Invention The present invention will now be explained with reference to FIGS. 3 and (i).

FIG. 3 is a front view of a terminal forming hoop body similar to FIG. 2. Is figure 4 a series of figure 3? It is a figure showing a partial cross-sectional shape.

In FIG. 3(a), 12 indicates the processing to be provided in this embodiment.
orrugat-1on) part.

? , L4 conductive spring +4 For example, a phosphor bronze plate with a spring thickness of 0.2 m is surface treated with tin-lead alloy plating.・The main functional parts of the Tsuko molded body itself are given the same reference numbers as in FIG. 2 showing an example of the conventional configuration. For example, 11 minutes of the U-shaped contacts related to the 26L molded "ml pot body cross-over", or 5 is the insulation breaking grip part of the connecting wire. Reference numeral 13 in the center of the gripping portion 5 is a conventional collage game 7-day lock.

The cross-sectional shape of the connecting part 12 of the one-noya-shaped terminal body with the lower side branch 9 is shown in FIG. ) The example shown in the figure may be used, but ε is provided in the press die for forming the terminal, and is engraved at the same time at the beginning of pattern punching in the shape shown. In this way, the support strength for 14 consecutive days is increased.

Hanging', 3 Kitakari (b)! kR(-ma, (a)! This is an example diagram different from the bacterium.

In this case, the collage cages 12 and 13 are arranged in series to obtain support strength equivalent to that shown in FIG.

By providing the collagen game VH 12 with such a convex or concave cross section, it is no longer necessary to provide the conventional upper side branch 8, and the conventional problem of contact 1 part 2 that occurs when cutting the upper crosspiece 8 is eliminated. The hoop molded body can be handled easily without problems such as deformation.

(gl) As described above, according to the terminal molded body of the present invention explained in the examples,
Continuous molding using a hoop machine similar to the conventional method can be carried out without reducing the processing stiffness of the molded product.
