Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector used for a signal transmission cable in a device such as a communication device or a computer, or an interface between devices.

FIG. 1 is a schematic diagram showing a male connector 1 with a guide and a female connector 2 that have been used conventionally.

There are two types of male connectors 1 with guides, one with and one without the clamping part 1-a, and the latter is generally used more often.

In the former case, the rear part of the engaged female connector 2 is held by the clamping part 1.
-a has a structure in which it is clamped and fixed, and if both connectors are connected and fixed with clamping part 1-a, a complete connection can be obtained, but the structure is complicated, the cost is high, and the width of the connector itself is wide. In today's world, where high-density packaging is required as devices become faster, their practicality is limited.

In the latter case, too, the width becomes too wide and it lacks practicality.

FIG. 2 is a diagram showing a male connector 3 without a guide.

Currently, this connector is very practical when considering cost and connector width for high-density mounting, but as shown in Figure 3, pins and connector contacts can be damaged due to incorrect insertion or vertical tilting. There are some drawbacks.

An object of the present invention is to provide a connector that can be easily and easily mounted.

The connector of the present invention is arranged at positions on both sides of an insertion passage for a printed board, a connector part attached to the printed board, and a cable connector attached to the printed board and engaged with the connector part, and the cable connector is inserted into the printed board. It is composed of a cylindrical member that serves as a guide.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 4 shows a connector guide 4, which is a feature of the present invention, and because it has a simple shape, it can be made of various materials such as various plastics and aluminum.

FIG. 5 is a schematic diagram of the connector guide 4 of the present invention mounted on a printed circuit board 5 having a female connector 2 and a signal transmission cable 7. The projections 4-a of the connector guide are inserted into the insertion holes 6 provided at both ends of the connector guide 4, and can be fixed by many methods such as heat welding, eyelets, screws, etc. depending on the material of the connector guide 4.

Note that a cable holder for pressing the cable 7 is attached to the printed board 5.

FIG. 6 is a state diagram when the male connector 3 mounted on the motherboard 9 and the female connector 2 mounted on the printed board 5 are mated, and the connector guide 4 is connected to the mating male connector. It holds the type connector 3.

Note that as long as the connector guide 4 is in a position to sandwich the mating connector, it goes without saying that the same structure can be obtained even if it is mounted on the motherboard 9 side.

From the above, by using the connector guide of the present invention, the connector guide acts as a stopper to prevent incorrect insertion, and even if the connector guide is made cylindrical and the insertion hole of the printed board is larger than the outer diameter of the protruding part of the connector guide. If the connector guide 4 is designed to rotate freely, it can be easily inserted without damaging the pins or contacts of the connector, and both the male and female connectors are completely sandwiched between the printed circuit board 5 and the motherboard 9, and are tilted vertically. Furthermore, connector guides at both ends prevent tilting to the left or right, resulting in stable mounting and improved operability.

[Brief explanation of the drawing]

FIG. 1 is a perspective view showing a conventional male connector with a guide and a female connector. FIG. 2 is a perspective view showing a male connector without a guide portion. FIG. 3 is a perspective view showing the engaged state of a male connector without a guide portion and a female connector. FIG. 4 is a perspective view showing a connector guide that is a feature of the present invention. FIG. 5 is a diagram showing the present invention-an embodiment, and FIG. 6 is a diagram showing an embodiment of the invention.
6 is a perspective view showing a state in which the connector of FIG. 5 is mounted on a motherboard. FIG. 1 to 6, 1 is a male connector with a guide part, 2 is a female connector, 3 is a male connector without a guide part, 4 is a connector guide, 5 is a printed board, 6 is an insertion hole,
7 is a signal transmission cable, 8 is a cable holder, and 9 is a motherboard.

Claims (1)

[Claims for Utility Model Registration] A printed board, a connector section attached to the printed board, and a cable connector disposed on both sides of an insertion passage for a cable connector attached to the printed board and fitted into the connector section. A cylindrical member that serves as an insertion guide for the cable connector.
