Description

Wire clamping device

Technical Field

The utility model relates to the field of electricity, in particular to a lead fixing device, and particularly relates to a lead clamping device.

Background

In electrical connectors, wire clamping devices are commonly used to clamp and secure wires. In the prior art, when the wire clamping device for the groove-shaped electric conductor is assembled, the positioning capacity and the accuracy between the wire clamping device and the groove-shaped electric conductor are poor. After the wire clamping device is installed in the groove-shaped conductor, excessive interference is easy to occur, fatigue is not resisted, and the service life is short.

Disclosure of Invention

The utility model aims to provide a wire clamping device, which aims to solve the technical problems of poor positioning capability and accuracy and short service life between the wire clamping device and a groove-shaped conductor in the prior art.

The utility model discloses a lead clamping device which comprises a first elastic arm, a second elastic arm, a third elastic arm, a fourth elastic arm, a fifth elastic arm and a sixth elastic arm, wherein the first elastic arm, the second elastic arm, the third elastic arm, the fourth elastic arm, the fifth elastic arm and the sixth elastic arm are sequentially connected, the second elastic arm is parallel to the horizontal direction, the third elastic arm is U-shaped, the fourth elastic arm is bent inwards, the fifth elastic arm is bent inwards and then bent outwards, and the sixth elastic arm vertically extends downwards.

Furthermore, the fifth elastic arm is arc-shaped.

Further, the widths of the first elastic arm and the sixth elastic arm are smaller than the widths of the second elastic arm, the third elastic arm, the fourth elastic arm and the fifth elastic arm.

Compared with the prior art, the utility model has positive and obvious effect. According to the utility model, the sixth elastic arm and the fifth elastic arm respectively form supports with the first position and the second position of the groove-shaped conductor, so that the positioning capability and the assembling accuracy during assembling are improved; the fifth elastic arm adopts an arc design and forms a vacancy avoiding position with the groove-shaped conductor, so that excessive interference is not generated when the tension spring is installed in the groove-shaped conductor. When the second elastic arm is pressed, the fourth elastic arm and the fifth elastic arm can simultaneously generate elastic deformation, so that the respective bearing force can be reduced, the fatigue resistance of the tension spring is improved, and the service life of the tension spring is prolonged.

Detailed Description

The present invention is further described with reference to the drawings and examples, but the present invention is not limited to the examples, and all similar structures and similar variations using the present invention should be included in the scope of the present invention. The use of the directions of up, down, front, rear, left, right, etc. in the present invention is only for convenience of description and does not limit the technical solution of the present invention.

Example 1

As shown in fig. 1, 2 and 3, the wire clamping device of the present invention includes a first elastic arm 1, a second elastic arm 2, a third elastic arm 3, a fourth elastic arm 4, a fifth elastic arm 5 and a sixth elastic arm 6, which are connected in sequence, wherein the second elastic arm 2 is parallel to the horizontal direction, the third elastic arm 3 is U-shaped, the fourth elastic arm 4 is bent inward, the fifth elastic arm 5 is bent outward, and the sixth elastic arm 6 extends vertically downward.

Further, the fifth elastic arm 5 is arc-shaped.

Further, the widths of the first elastic arm 1 and the sixth elastic arm 6 are smaller than the widths of the second elastic arm 2, the third elastic arm 3, the fourth elastic arm 4 and the fifth elastic arm 5.

The working principle of the embodiment is as follows:

1. the utility model is used for clamping and fixing the lead 15 and is arranged in the groove-shaped electric conductor 7.

2. The sixth elastic arm 6 and the fifth elastic arm 5 respectively form supports with a first position 11 and a second position 12 of the groove-shaped conductor 7, so that the positioning capability and the assembling accuracy during assembling are improved; in the mounted state, the first spring arm 1 is mounted at a side wall 13 of the channel conductor 7.

3. The fifth elastic arm 5 adopts an arc design and forms a vacancy avoiding position with the groove-shaped electric conductor 7, so that excessive interference is not generated when the tension spring is installed in the groove-shaped electric conductor 7.

4. The third elastic arm 3 adopts a U-shaped design and can be matched with a support column 8 on the insulating part shell, and the support column 8 can support a tension spring.

5. When the second elastic arm 2 is under the downward acting force of the button, the reverse arc-shaped design of the inward bending of the fourth elastic arm 4 is ingenious, the required force during pressing can be effectively reduced, and the use hand feeling and the use quality are improved, as shown in fig. 3.

6. When the second elastic arm 2 is pressed in the direction of the arrow in fig. 2, the fourth elastic arm 4 and the fifth elastic arm 5 are elastically deformed at the same time, so that the respective bearing force can be reduced, the fatigue resistance of the tension spring can be improved, and the service life of the tension spring can be prolonged.

7. As shown in fig. 1, the first elastic arm 1 and the sixth elastic arm 6 have a narrow width, so that the tension spring is locally deformed first when being stressed, and the rest elastic arms are elastically deformed gradually as the external force increases.
