Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is useful when connecting electronic devices via cables. This invention relates to a cable connection connector.

0002

[Conventional technology]

As conventional cable connection connectors, there are those shown in FIGS. 3 and 4.

0003 A male block 1 made of synthetic resin in the shape of a rectangular parallelepiped, and a female block that fits into the male block 1. The male block 1 and the female block 2 are provided with respective wirings 3a, 3b, 3. c, and contact pins 5a, 5b, 5c, and 6a, 6 connected to 4a, 4b, 4c. b, 6c are planted and the male block 1 and female block 2 are fitted The contact pins 5a, 5b, 5c and 6a, 6b, 6c are fitted into each Wirings 3a, 3b, 3c and 4a, 4b, 4c are electrically connected. be.

0004 Further, a lock claw 7 is provided on the side surface of the male block 1, and the male block 1 and the female block are connected together. When the lock 2 is fitted, the lock pawl 7 engages the locking claw 7 formed on the side surface of the female block 2. The male block 1 and the female block 2 are engaged with each other in the stopper hole 8 to maintain the fit between the male block 1 and the female block 2. There is.

[0005] The male block 1 and female block 2 are attached to the free end of the cable or Used by being fixed to the equipment chassis.

[0006]

[Problems to be solved by ideas]

However, with the conventional connector, the two electronic devices to be connected are not fixed. There is no particular problem when the two electronic devices rotate relative to each other as shown in Figure 4. , the cable 9 is twisted, and a great deal of stress is generated on the cable 9.

[0007] For this reason, there is a limit to the amount of rotation of electronic devices, and the use of electronic devices for a long period of time is limited. For models that rotate frequently, poor connector contact, disconnected wiring, etc. There is a possibility that

[0008] In view of these circumstances, this invention allows for free rotation and reduces the load on the cable due to rotation. This is an attempt to relieve the burden.

[0009]

[Means to solve the problem]

In this invention, a male block and a female block are rotatably fitted, and both blocks are At least one of the contacts provided in the block is provided with contacts concentrically multiplexed. , the contacts provided on the other block can slide into contact with the contacts provided in the concentric multiplex. It is characterized by this.

0010

[Effect]

The contacts provided on at least one block are in a concentric multiple arrangement, and the contacts on the male block are Since the block and female block rotate in a fitted state, the contact provided on the other block The concentric multiple contacts are slidably contacted, and the electrical connection between the contacts between both blocks is maintained. .

[0011]

【Example】

An embodiment of the present invention will be described below with reference to the drawings.

0012 Components that are the same as those shown in Figures 1, 2, 3, and 4 are given the same reference numerals. There is.

[0013] The male block 10 has a circular cross-sectional shape, and a locking claw is provided on the side surface of the male block 10. form 7. Contacts 11a, 11b, 11c are provided on the connecting surface side of the male block 10. Bury it. The contacts 11b and 11c are ring-shaped, with the contact 11a being the center. Arranged concentrically and in a stepped manner. Also, between each contact 11a and 11b, 11b and 1 Insulating materials 12a, 12b are interposed between the contacts 11a, 11b, 11 C is insulated.

[0014] The female block 13 has a cylindrical shape into which the block 10 fits, and has a shape on its outer circumferential surface. A lock groove 14 is formed in which the lock pawl 7 engages. Inside the female block 13 The portion includes contacts 15a, 15b, 15c that abut the contacts 11a, 11b, 11c. will be established. The contacts 15a, 15b, 15c are the contacts 11a, 11b, 11c. Similarly, the contact point 15a is concentrically multiplexed, and the contacts 11a, 11b, 11c and are arranged in a reverse staircase shape, and each contact is insulated with insulating materials 16a and 16b.

[0015] When connecting a cable through a connector, the male block 10 and the female block 13. From the fitting of the male block 10 and the female block 13 , the contacts 11a, 11b, 11c are in contact with the contacts 15a, 15b, 15c, respectively. However, the wirings 3a and 4a, the wirings 3b and 4b, and the wirings 3c and 4c are electrically connected, respectively. Continue.

[0016] Further, the lock pawl 7 engages with the lock groove 14 and connects the male block 10 with the lock groove 14. The fitted state with the female block 13 is stably maintained. Furthermore, the male block 10 and the front Female block 13 and contacts 11a, 11b, 11c and contacts 15a, 15b, 15 Since both of c are circular, the male block 10 and the female block 13 is capable of relative rotation, and the stepped arrangement of each contact point regulates the radial displacement of the contact points. control

[0017] When the male block 10 and the female block 13 rotate relative to each other, the contacts 11a, 11b, 11c and contacts 15a, 15b, 15c are in sliding contact, and the lock claw 7 is It slides in the lock groove 14.

[0018] Therefore, the male block 10 and the female block 13 do not place any burden on the cable. They can be rotated with each other without hanging.

[0019] Note that the radial wobbling between the male block 10 and the female block 13 can be reduced. If so, there is no need to arrange the contacts in a stepped arrangement. Also, the contacts on one side are arranged concentrically. Of course, if provided, the other side may be a point-like contact.

[0020]

[Effect of the idea]

As described above, according to the present invention, connectors can be used in rotating and movable parts of electronic equipment. This eliminates the burden on the cable due to rotation and allows rotation of more than 360°. It has the excellent effect of eliminating restrictions on the rotation angle.
