The same symbols are applied to the elements common to the conventional example. The same applies to the following figures.

In FIG. 1, the case of the completed connector 1 is formed by laminating and fixing a resin mold body 4 and a substrate 5, and the pin hole 4b of the resin mold body 4 slides only on the tip end portion of the pin 2. A coaxial and large-diameter cylindrical space 4c which is exposed as much as possible and which follows the pin hole 4b accommodates the flange portion 2a of the pin 2 and the coil spring which is the spring member 3 for pressing the pin 2 toward the tip side. The substrate 5, which is a relatively thin plate member, encapsulates these. A part of the spring member 3 is inserted into the deep hole 2b provided in the pin 2 so that a long coil spring can be used to give the pin 2 a long stroke, and the pressure change is moderated.

As shown in the front view (b) and the back view (c) of FIG. 1, through holes 4 a, are formed at the four corners of the resin mold body 4.

All or part of the conductive film formed on the inner surface of each through hole is electrically contacted with the spring member 3 and the pin 2 via the conductive pattern formed on the surface of the resin case 4 or the substrate 5. Connected. A back pattern 5c is provided on the back surface of the substrate 5 and is connected to the conductive film in the through hole 5a.

The upper circuit conductive pattern (not shown) is soldered by the solder 8 (the conductive film on the inner surface of the through hole acts as a side electrode that ensures the wet up of the solder), and the pin 2 is a circuit pattern of the circuit board 7. It becomes the terminal contact. The connector 1 can also be mounted upright on the circuit board 7 with the board 5 facing down (pins 2 facing up). In this case, the conductive film of the through hole 5a and the back pattern 5c (also a side electrode depending on the orientation of the connector) are also connected to the circuit pattern on the circuit board 7.

A large number of connectors 1 of the present invention are simultaneously manufactured by a so-called multi-cavity manufacturing method, and finally separated. 3 and 4, in order to explain the main points of the manufacturing method, the resin mold body and the substrate (the material is an insulating material similar to that of the circuit board) forming the case of the connector which is an example of the embodiment of the present invention. Is described as)
Large size (large area) before cutting / separating into individual connectors
In the state of the aggregate material, the shape and processing of a part thereof are shown.

FIG. 3 shows a part of the collective resin mold body 40 which is a material before the resin mold body 4 is cut and separated.
(A) is a front view (the front is the surface on the tip side of the pin),
(B) is a sectional view taken along the line AA, and (c) is a rear view. At the time of molding, the aggregate resin molded body 40 is provided with a large number of holes for the through holes 4a, pin holes 4b, and cavities 4c, and a conductive film (shown as a dotted surface) is formed on the surface including the inner surface of the through holes 4a. Are formed.

Reference numeral 10 indicates a position of a cut surface at which the aggregate resin molded body 40 is finally cut vertically and horizontally (cutting is performed after the connector is assembled). Each through hole 4a
Is located at the position where it crosses each of the intersecting cut surfaces. Therefore, after cutting, the conductive film on the inner surface of the through hole is used as the side surface electrode film of the connector 1 as shown in FIG. 1 (b), (c) or FIG. Appears outward at the edge of the ridge. The side surface electrode film is a conductive film on the back surface of the collective resin case 40 or the space 4

The collective substrate 50 has a through hole 5a, a front pattern 5b on the inner surface of the case, which is in contact with the rear end of the spring member, and a back pattern 5c which is exposed on the back surface of the connector 1. The predetermined pattern of the front pattern 5b and all of the back pattern 5c are
It is connected to a conductive film formed on the inner surface of the through hole 5a. When the collective substrate 50 is separated at the cutting surface 10, FIG.

A method for producing and assembling a multi-piece connector 1 according to the embodiment of the present invention will be described. Figure 5
(A) is a sectional view showing an important part of an assembly process of an aggregate layered product in an example of an embodiment of the invention. First, as shown in FIGS. 3 and 4, a large aggregate resin mold body 40 and an aggregate substrate 50, which have been subjected to predetermined processing, are prepared. Next, the front surface of the aggregate resin molded body 40 is placed horizontally with the front side facing downward, and the pins 2 facing downward in all the cavities 4c, and then the pins 2
The spring member 3 is put in. Further, the collective substrate 50 is provided on the upper surface.
Is pressed in the direction indicated by the arrow 70 and adhered to encapsulate the pin mechanism. A heat resistant adhesive sheet is used as the adhesive. Finally, a cut surface 10 is obtained by cutting the laminated joined body (collective laminated body).
Along the way, using a dicer or a slicing machine, it is possible to obtain a large number (for example, several hundreds) of completed connectors all at once.

FIG. 5B is a sectional view showing an essential part of a process for assembling the aggregated laminate in another example of the embodiment of the present invention. In this example, unlike the previous example, the pin hole is provided not on the collective resin mold body 40 side but on the collective substrate 50 side. A large number of pins 2 and spring members 3 are put into the pin holes 5d of the lower collective substrate 50, and the collective resin mold body 40 is covered and pressed onto and bonded to form a collective laminate, which is cut and separated. .

In any of the embodiments, the shape structure up to the aggregated laminated body is the same (common),
When this is cut and separated, if the vertical or horizontal cut surface 10 is thinned out from the state of FIG. 3 or FIG. 4 to leave every other one, the completed connector includes two pins. Further, from FIG. 3 and FIG. 4, a completed connector including three pins can be obtained by thinning out two adjacent cutting faces from a set of three cutting faces. Further, in these cases, the plurality of pins included in one completed connector are electrically insulated from each other, and each pin is connected only to the conductive film on the inner surface of the specific through hole which becomes the external electrode terminal. However, this can be easily achieved by appropriately changing the shapes of the surface electrode pattern of the collective resin mold body 40 and the front pattern or the back pattern of the collective substrate 50.

Although one example of the embodiment of the present invention has been described above, the embodiment of the present invention is not limited to this. For example, the shape of the pin, the presence or absence of a deep hole into which a part of the spring member is inserted, the spring member of another shape (for example, a leaf spring or a rubber material), the shape of the resin case or the board, the shape of the pattern, the position of the through hole ( For example, a conductive surface close to a semicircle can be obtained by straddling only one cut surface), a bonding method, a cutting separation method, and the like can be freely changed. In addition, the number of contact pins included in one completed connector can be arbitrarily set by appropriately selecting the intervals between the cut surfaces.
Further, the material of the substrate 5 may be replaced with a metal plate. Various other additions, changes, and deletions are possible.

[0021]

According to the present invention, since a large number of connectors are manufactured and assembled all at once in a collective state, and then the individual connectors are cut and separated at once, the number of steps per connector is drastically reduced from the conventional product. The cost can be reduced significantly. In addition, by changing the cut surface, the number of pins per connector can be arbitrarily adjusted. Further, since it is not necessary to insert-mold or press-fit the pin case into the frame, a mold for that is not necessary, and it is not necessary to add an electrode plate, so that there is a cost reduction effect.
In addition, various excellent effects are exhibited, such as mounting in a vertical or horizontal direction on a circuit board.
