The purpose is to reduce the contact pitch, narrow the contact pitch, and adapt to multiple arrangements.The ground connection piece is placed in the center, the signal connection pieces are placed on the left and right of it, and the holder holds the ground connection piece in the center, with the signal connection pieces placed on the left and right of the ground connection piece. is provided with contacts, each signal line of the two coaxial cables is connected to the other end of the signal connection piece, and the shields of the two coaxial cables are connected together to the other end of the ground connection piece to form a set of contacts. A plurality of sets of contact combinations are housed and fixed in parallel inside the connector main body.

[Industrial application field]

This invention is a connector for coaxial cables, especially 2
This invention relates to a connector configured with a set of coaxial cables.

In recent years, the number of pins has increased as printed circuit boards have become more densely packaged, and as a result, the pins tend to be arrayed in a narrower pitch. Therefore, when connecting cables and contacts in connectors, it is necessary to organize the signal side to make it adaptable to multiple arrangements.
Ideas such as sharing the ground side and narrowing the contact pitch are desired.

[Conventional technology]

Therefore, conventional coaxial cable connectors mainly provide contacts for each cable. That is, since a coaxial cable has at least one signal line and a ground shield, contacts are separately connected and provided for each of these signal lines and shields.

[The problem that the idea aims to solve]

By the way, in the conventional device described above, each coaxial cable has a contact, so as the number of cables increases, the number of ground contacts also increases. Furthermore, since the cables are separated one by one, there is a problem that it becomes complicated to put them together.

The present invention was created with these points in mind. It combines two coaxial cables into one pair, shares the ground, reduces the number of contacts, narrows the contact pitch, and adapts to multiple arrangements. The purpose of the present invention is to provide a connector for coaxial cables that can be used for coaxial cables.

[Means to solve the problem]

In order to achieve the above object, the connector of the present invention has a ground connection piece in the center, signal connection pieces on both left and right sides of the ground connection piece arranged in a straight line, held by a holder, and a contact provided at one end of these connection pieces. Connect each signal line of the two coaxial cables to the other end of the signal connection piece, and connect the two signal lines to the other end of the ground connection piece.
The shields of the two cables are connected together to form a set of contact combinations.

A plurality of sets of these connector combination bodies are accommodated and fixed in parallel in the same direction inside the connector main body.

[Effect]

Based on the above configuration, the contact combination has one ground contact for two coaxial cables.
Two coaxial cable signal line contacts are placed at a narrow pitch on either side of the central ground contact. Therefore, the two signal contacts of one set of contact combinations are arranged and used for inputting and outputting the same signal.

In this way, with this invention, the number of ground contacts is reduced by half compared to the number of coaxial cables, which makes the pitch narrower and more compact.By combining two coaxial cables into a single pair, usage patterns can be organized and multiple pin arrangements can be accommodated. It becomes possible.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In Figure 1, reference numeral 1 denotes a bowl-shaped connector body, 2 a cover that is attached to the open side of the main body 1 to protect cables, etc., and three rows of pin insertion holes 3 are provided at the bottom of the connector body 1. The contact assembly 1 is placed directly above the first, second, ... hole 3 in each row.
Multiple sets of 0 are housed and fixed in parallel.

In FIGS. 2a and 2b, the contact assembly 10
Specifically, there is a long plate-shaped ground connection piece 11 in the center, and short plate-shaped signal connection pieces 1 on the left and right sides.
2 and 13 are arranged in a straight line with a predetermined gap, and are integrated by a wide resin holder 14 at the intermediate constrictions 11b, 12b, 13b of these connecting pieces 11, 12, 13. Fork-shaped contacts 11a, 12a, 13a are formed in the same row at the lower end of each connection piece 11, 12, 13,
Above the signal connection pieces 12 and 13, two coaxial cables 15 and 16 are arranged substantially in the same line, respectively.

And the signal line 15 of each cable 15, 16
a, 16a are the upper ends 12c of the connecting pieces 12, 13,
13c using a heat shrink tube 17. On the other hand, the upper end of the ground connection piece 11 extends above the signal line and branches into two forks, with each end 11c, 1
1d is the shield 1 of cables 15 and 16 as it is
It is soldered in contact with 5b and 16b. Furthermore, in the holder 14, the constricted portions 11b, 12b, 11
A clamp pin hole 17 penetrates between b and 13b,
A protrusion 18 extending downward from the front surface provides directionality.

On the other hand, in the connector main body 1, as shown in FIG. 1, a contact hole 4, a protrusion step 5, a pin hole 6, and a combined body storage chamber 7 are formed directly above the hole 3. Therefore, the combined body 10 is housed inside the housing chamber 7 in the direction in which the projection 18 is engaged with the stepped portion 5, and each contact 11a, 12a, 13a is inserted into the hole 4 thereof. Similarly, other sets of combined bodies 10 are accommodated in parallel in the same direction, and at this time, the wide holder 14
Comrades are in contact and keeping distance. After all the combined bodies 10 are housed, the pin holes 6 to 17 are
By inserting the clamp pin 19 into the joint body 10
is fixed in place.

With the above configuration, when the connector main body 1 is inserted into the pin on the printed board side, the pin enters the inside of each contact 11a, 12a, 13a from the pin insertion hole 3 and engages with it, thereby establishing a plug-in connection.

[Effect of idea]

As described above, according to the present invention, two coaxial cables are combined into a pair and a common ground is used, so the number of grounds is halved, resulting in a smaller size and narrower pitch.

Since the signal system is located on both sides of each contact assembly with the ground in between, this is effective as a countermeasure against noise and the manner of use can be streamlined.

Since the cable is soldered in a straight line, there is less risk of breakage.

The directional nature of the assembly prevents incorrect assembly.

Since the combined bodies are assembled side by side in the same direction,
The number can be increased or decreased arbitrarily.
