Description

[Detailed Description of the Invention] Technical Field The present invention relates to a multi-pin connector used in audio equipment, video equipment, etc.

PRIOR ART FIG. 1 is a diagram showing a conventionally commonly used two-pin connector, and FIG. 1a shows the overall configuration in a completed state. 3 is a central pin connection terminal [see figure b], 4 is the outer circumference of the pin, and 5 is a lead wire. Figure b shows each pin plug as a single unit, to which lead wires are connected by soldering etc. as shown in figure c, and then the molding die 6 is assembled as shown in figure d.
It was attached via a fixed pitch guide and molded by press-fitting plastic resin into vinyl chloride or the like to obtain an integrally molded finished product as shown in Figure a.

However, conventional multi-pin plugs manufactured by such a method have the following drawbacks during manufacture or use.

() During preliminary processing, the number of soldering steps is large and it takes time.

() Processing cost is high.

() Easily shrinks due to heat during molding, easily causing twisting and deformation.

() The pitch between pins and plugs tends to change due to the reasons in ().

() Due to the reasons () to (), there are many difficulties in making two or more series.

() The plug pin must have a long structure to prevent it from coming off or swaying after molding.

Purpose The present invention was developed in view of the above circumstances, and there is no lateral wobbling or pitch shift after molding, and
It is an object of the present invention to provide a multi-pin connector with simplified wiring and high reliability.

Configuration In order to achieve the above object, the present invention attaches the male sides of a plurality of US pin connectors to a single insulating plate, and connects the male sides of the US pin connectors to the front or back surface of the insulating plate. The device is characterized in that it has a printed wiring pattern and is integrally molded. Hereinafter, the configuration of the present invention will be explained based on examples.

FIG. 2 is a diagram showing an embodiment of the present invention. As shown in FIG. The wire rods 12 are connected as shown in FIG. 1B after being attached at pitch intervals by an appropriate method such as caulking, fusing, or gluing. By attaching two pin plugs to one insulating plate in this way, the pitch between the pin plugs is fixed, so even if plastic resin is injection molded by press-fitting etc. into an integral mold, the pitch will not shift. In addition, a stable pitch can be obtained without lateral wobbling or pitch deviation after molding.

FIG. 3 is a diagram showing another embodiment of the present invention,
Insulating plate 2 that fixes the male side 20 of the US pin plug
1 is a printed wiring board with conductor patterns 2 on both sides.
2 and 23 to further simplify the wiring, and by doing so, the reliability of the connection can be further improved. In the same figure, a is the upper pattern 2.
2, which is connected to the center pin of the pin plug 20. FIG. 2B shows the lower pattern 23, which is electrically connected to the outer circumference of the pin plug 20. In this case, if both are at the same potential (for example, earth potential), the pattern 23 is not necessary, and a conductor such as a full-face copper plate may be used. FIG.

FIGS. 4a to 4c are diagrams showing the conductor patterns on the front and back sides of the insulating plate for fixing the pin plug, respectively. The left side shows the front side, the right side shows the back side, and the back side in b shows the case where the entire surface is a conductor.

Although an example in which the present invention is applied to a double-pin connector has been described above, the present invention is not limited to the above embodiment. For example, as shown in FIGS. 5 to 7, , 2 x 2 or 3 or more units may be installed on the same board. Furthermore, as shown in Figures 8 and 9, the male side of the US pin plug may be installed on the front and back of the same board. In that case, one pin plug can be converted into two pin plugs, or it can be used as a stereo to monaural conversion adapter.

Effects As described above, according to the present invention, the male sides of multiple US pin plugs are attached to a single insulating plate, so the pitch between the pin plugs is fixed, so plastic resin can be injection molded by press-fitting etc. Even when integrally molded, no pitch deviation occurs, and a stable pitch can be obtained without lateral wobbling or pitch deviation after molding. In addition, by forming conductor patterns on both sides of the insulating board that attaches the male side of the US pin plug as a wiring board,
Wiring is simplified and connection reliability can be improved.
