Description

[Detailed description of the invention] (1) Technical field of the invention The invention relates to a connector cover for a cable connector connected to input/output pins of a printed circuit board, etc., and in particular a two-stage connector cover in which two connectors are mounted close to each other vertically. This invention relates to a connector cover that can reduce the mounting space of a stacked connector.

(2) Prior Art and Problems As shown in FIG. 1, the conventional connector cover 1 has the same thickness from the clamp portion 3 of the cable 2 to the joint portion 5 of the connector 4.

Here, when the diameter d of the cable 2 is smaller than the thickness t of the connector 4, the thickness t' of the connector cover 1 can be made approximately the same as the above t;
When d is larger than the thickness t of the connector 4, the thickness t' of the connector cover 1 must be slightly larger than the above d, so the thickness t' of the connector cover 1 is the thickness of the connector 4. becomes larger than t.

In this state, if the two connectors 4 and 4' are mounted vertically close to each other in two layers, as shown in Fig. 2,
Since t'>t, even if the connector covers 1 and 1' are brought into close contact, a gap is created between the connectors 4 and 4', and the center-to-center distance 1 becomes large.

Therefore, in mounting the two-tiered connectors 4, 4', the diameter d of the cables 2, 2' and the connector covers 1, 1
It has been impossible to reduce the mounting space due to the limitation of the thickness t'.

For this reason, even if connectors are mounted in two layers for high-density mounting on the input/output pins of printed circuit boards, etc., the mounting space between the connectors cannot be reduced very much, so in the end, multiple layers are stacked vertically on back panels, etc. The mounting interval between printed circuit boards to be mounted could not be made very small, and the mounting density could not be increased.

(3) Purpose of the invention The present invention was made in response to the above-mentioned circumstances, and aims to provide a connector cover that can reduce the mounting space in a two-tiered connector in which two connectors are mounted close to each other vertically. purpose.

(4) Structure of the invention and the above-mentioned object is, according to the invention, a connector for connecting to the above-mentioned connector a cable in which the diameter of the cable connected to the two-tiered connector is greater than the thickness of each individual connector of the two-tiered connector. In the cover, the connector cover includes a cable clamp part into which the proximal end of the cable is inserted and clamped and held, and a cable core extending from the cable clamp part toward the connector at the distal end and connecting the core wire of the cable branched inside the cable clamp part to the connector. It has a cover main body that protects the connecting part and the connector provided at the distal end of the cover main body, the thickness of the cover main body is the same as the thickness of the connector, and the cable clamp part This is achieved by providing a connector cover characterized in that the connector cover is biased toward one corner of the cover main body, and one side is bulged out to protrude in the cable insertion direction.

(5) Embodiments of the invention Hereinafter, embodiments of the invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view showing the connector cover 11 according to the present invention, and FIG. 4 is a perspective view showing the connector cover 11 upside down.

This connector cover 11 covers the cable 1 for signal transmission and reception, etc.
2 to a connector 13 inserted into an input/output pin of a printed circuit board, etc., and has a cable clamp part 14 at its base end and a cover main body 15 at its distal end.

The cable clamp section 14 inserts the proximal end of the cable 12 along with its outer sheath and holds it in place. This is to protect the part where the cable core wire branched inside the cable is connected to the connector 13.

Here, the connector cover 11 according to the present invention has a diameter d of the cable 12 mounted thereon which is larger than the thickness t of each connector 13 of a two-tiered connector in which two connectors 13 are mounted close to each other vertically. The thickness t□ of the cable clamp portion 14 is made slightly larger than the diameter d of the cable 12, and the cover main body 1
The thickness of the connector 13 is the same as the thickness t of the connector 13 described above.

Further, the cable clamp section 14 is shown in FIGS. 3 and 4.
As shown in the figure, the cover body 15 is provided so as to be biased toward one corner of the proximal end thereof, and is bulged only on the lower side (lower side in FIG. 3) and on the other side. The edge (upper surface edge in the figure) is flush with the side surface of the cover main body 15.

Furthermore, as shown in FIG. 3, the cable clamp section 14 is formed to protrude by an appropriate length in the insertion direction of the cable 12.

Therefore, a notch 16 is formed on the side thereof.

In order to mount a two-tiered connector using the connector cover 11 configured in this way, as shown in FIG.
Connector cover 11 to which one connector 13 is connected and connector cover 11 to which the other connector 13' is connected
'', so that the cable clamp portions 14.14' are inserted into the corresponding notch 16.16' with the bulging direction facing inward, and the connectors 13.13' are inserted into the corresponding input/output pins. Bye.

At this time, as shown in FIG. 6, the cable clamp portions 14, 14' of each connector cover 11.11' can escape by entering the notch 16.16' of the other, so that the two connectors 13°13' can be mounted closely vertically.

Therefore, as shown in FIG.
．． The cable 12 connected to this has a thickness t of 13'.
．． Even if the diameter d of the connector 12' is larger, the two connectors 13 and 13' can be closely mounted and the distance 1' between their centers can be reduced.

In addition, since each cable clamp part 14.14' protrudes by an appropriate length in the direction of insertion of the cable 12, the two connector covers 11.11 are attached as shown in FIG.
There is an appropriate distance C between the side surface of the cable clamp 7'' portion 14' of one connector cover 11' and the side surface of the cover main body 15 of the other connector cover 11 when the two connector covers 11' are combined.
is formed, and by using this gap C, each connector cover 11.11' can be pushed in or pulled out in the insertion/removal direction, and each connector 13.
13' can be inserted and removed individually.

(6) Effects of the invention Since the invention is constructed as described above, it is possible to connect the two connectors 13, 13' vertically and closely together without being restricted by the diameter of the cable 12, 12' in a two-tiered connector. can be mounted, and the mounting space can be reduced.

Therefore, it is possible to reduce the mounting space when high-density mounting of connectors in two layers on the input/output pins of printed circuit boards, etc., and to reduce the mounting spacing of printed circuit boards that are mounted in multiple layers vertically on back panels, etc. The mounting density of printed circuit boards can be further increased.

Further, each of the connectors 13 and 13' can be individually inserted and removed as in the conventional case.
