Description

Technical Field

[0001] This utility model belongs to the field of line connector technology, and in particular relates to a multi-angle rotary connector for splicing connecting wires. Background Technology

[0002] When workers connect electrical circuits using wires, they need to connect two wires directly by stripping the insulation layer. This can easily lead to leakage between the wires and the connection is not secure. Therefore, it is often necessary to connect a plug to the wires and then connect them using a connector device.

[0003] However, existing technologies have some problems: although existing connectors can achieve electrical connection between two sets of wires, in actual use, the wires are often pulled and rotated. Existing connectors simply fix the two sets of wires together, making it difficult for the wire connection to withstand the rotational force. This can easily cause the wires to fall off the connector or the insulation layer of the wires at the connector to crack, affecting normal use. Therefore, we propose a multi-angle rotary connector for splicing connectors. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multi-angle rotating connector for splicing connecting wires, which can rotate at multiple angles after being connected by wires, thereby improving the applicability of the connector in different environments and ensuring normal use after the wires are connected.

[0005] This utility model is implemented as follows: a multi-angle rotary connector for splicing connecting wires includes a housing. Two spherical bearings are arranged in the middle of the inner wall of the housing. The outer ring of the spherical bearings is fixedly installed on the inner wall of the housing. Two crown springs are fixedly installed on the inner ring of the spherical bearings. A wire is fixedly connected between the two crown springs. Snap-fit ​​components are arranged on both sides of the housing. The plug of the connecting wire can maintain a stable connection with the housing through the snap-fit ​​components.

[0006] Optionally, the snap-fit ​​assembly includes a block hinged to the insertion hole of the housing, a spring fixedly connected to the block, and a snap-fit ​​block fixedly connected to the other end of the spring.

[0007] Optionally, the card block is provided with three ball bearings, which are movably mounted on the card block.

[0008] Optionally, a base is fixedly installed at the bottom of the housing, and a through hole is provided on the base.

[0009] Optionally, retaining rings are fixedly installed on both sides of the inner wall of the housing, and the retaining rings are configured as plates.

[0010] Optionally, the number of wires is four, and the four wires are evenly distributed and connected between the two crown springs.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, by incorporating a spherical bearing, a crown spring, and a wire, allows the operator to insert the wire plug into the crown spring during use. The inward pressure of the crown spring maintains contact with the wire plug, enabling axial rotation of the plug. Simultaneously, since the crown spring is fixedly mounted on the inner ring of the spherical bearing, the inner ring can deflect in any direction, allowing the wire plug to also deflect in any direction. This enables multi-angle rotation after wire connection, improving the connector's applicability in different environments and ensuring normal use after wire connection.

[0013] Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments of the present invention with reference to the accompanying drawings. Attached Figure Description

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] like Figures 1 to 5As shown in the figure, the multi-angle rotary connector for splicing connecting wires provided in this utility model embodiment includes a housing 1. Two spherical bearings 2 are provided in the middle of the inner wall of the housing 1. The outer ring of the spherical bearing 2 is fixedly installed on the inner wall of the housing 1. Two crown springs 3 are fixedly installed on the inner ring of the spherical bearing 2. A wire 4 is fixedly connected between the two crown springs 3. A snap-fit ​​assembly is provided on both sides of the housing 1. The plug of the connecting wire can maintain a stable connection with the housing 1 through the snap-fit ​​assembly.

[0022] Furthermore, the snap-fit ​​assembly includes a block 5, which is hinged to the insertion hole of the housing 1. A spring 6 is fixedly connected to the block 5, and a snap-fit ​​block 7 is fixedly connected to the other end of the spring 6.

[0023] After the plug of the wire is inserted into the housing 1, the operator engages the locking block 7 on the retaining ring of the wire plug, thus putting the spring 6 in a stretched state. Due to the restoring effect of the spring 6, the wire plug will be prevented from falling off the housing 1.

[0024] Furthermore, the card block 7 is provided with three ball bearings 8, which are movably mounted on the card block 7.

[0025] When the locking block 7 is engaged with the wire plug, the spring 6's elasticity causes the locking block 7 to exert a pulling force on the wire plug. Through the design of the ball bearing 8, the wire plug can still rotate axially well under the pulling force of the locking block 7, ensuring the feasibility of multi-angle rotation of the wire.

[0026] Furthermore, a base 9 is fixedly installed at the bottom of the housing 1, and a through hole 10 is provided on the base 9.

[0027] The design of the base 9 and the through hole 10 makes it easy for staff to use bolts to fix and install the entire housing 1.

[0028] Furthermore, retaining rings 11 are fixedly installed on both sides of the inner wall of the housing 1, and the retaining rings 11 are set in the shape of plates.

[0029] The retaining ring 11 can be made of rubber. When the wire plug is inserted into the housing 1, the retaining ring 11 can seal the gap area to prevent moisture from entering the housing 1. At the same time, because rubber is soft, it will not affect the wire plug and the crown spring 3 from deflecting in any direction under the action of the spherical bearing 2.

[0030] Furthermore, there are four wires 4, which are evenly distributed and connected between the two crown springs 3.

[0031] The conductor 4 can be made of flexible wire, so that it can conduct current without being affected by the position deflection of the crown spring 3.

[0032] Working principle and usage process of this utility model:

[0033] In use, the operator inserts the power cord plug into the crown spring 3. Then, the operator can engage the locking block 7 on the retaining ring of the power cord plug, thus putting the spring 6 in a stretched state. Due to the restoring effect of the spring 6, the power cord plug will not fall off the housing 1. When the power cord is pulled and rotated, the power cord plug can rotate axially in the crown spring 3. At the same time, since the crown spring 3 is fixedly installed on the inner ring of the spherical bearing 2, the inner ring of the spherical bearing 2 can deflect in any direction, thereby allowing the power cord plug to deflect in any direction as well. This enables the power cord to rotate at multiple angles after connection, thereby improving the applicability of the connector in different environments and ensuring normal use after connection.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
