Technical Field

[0001] This utility model relates to the field of pipe connector technology, and in particular to a single-hole galvanized steel cable connector with double-layer retaining springs. Background Technology

[0002] In home renovation, junction boxes are one of the electrical accessories. Junction boxes are used as transitions at the joints of wires (such as when the wire is long or the conduit needs to turn a corner). The conduit is connected to the junction box, and the wires inside the conduit are connected in the junction box, which serves to protect and connect the wires.

[0003] Existing cable connectors are generally connected to junction boxes by screwing them on. This connection method makes the installation of cable connectors very inconvenient, and disassembling the cable connectors is also very difficult when they are damaged after long-term use or when the junction box connectors need to be replaced for maintenance. Utility Model Content

Both springs have a round hole in the middle, and both front parts have two limiting pieces for limiting the manganese steel sheets of different sizes. The rear part of the second spring has two bent flanges for blocking the manganese steel sheets of different sizes and providing a force-bearing point.

[0008] Preferably, the outer end is provided with an upper outer ring stop, a lower outer ring stop, and an outer ring mounting part. The upper outer ring stop is fixedly connected to the outer ring mounting part through two mutually symmetrical bends. The upper outer ring stop and the outer ring mounting part are provided with bends to avoid gaps.

[0009] Preferably, the outer ring sidewall is provided with several symmetrically arranged outer ring buckles, which are used to engage with the junction box; at the same time, the outer ring sidewall is provided with two symmetrically arranged retaining buckles, which are used to cooperate with the lower retaining edge of the outer ring to fix the outer ring.

[0010] Preferably, the manganese steel sheet with large and small ends is in an inverted U-shape, including a manganese steel sheet connecting part, a small manganese steel sheet end, and a large manganese steel sheet end.

[0011] Preferably, the manganese steel sheet connecting part has a round hole in the center, the small end of the manganese steel sheet and the large end of the manganese steel sheet are arranged in parallel, with the small end of the manganese steel sheet in front and the large end of the manganese steel sheet behind, and both the small end of the manganese steel sheet and the large end of the manganese steel sheet have two fixing teeth.

[0012] Preferably, the upper end of the connector housing is fitted with a protective sleeve, which includes an extension portion and a sleeve portion. The sleeve portion is fitted onto the upper end of the connector housing, while the extension portion just covers the exposed housing wall, in order to protect the cable and prevent the cable sheath from being cut.

Detailed Implementation

[0024] To better understand the purpose, structure, and function of this utility model, the following detailed description of a single-hole galvanized steel cable connector with double-layer retaining springs is provided in conjunction with the accompanying drawings.

[0025] like Figure 1-8 As shown, this utility model provides a single-hole galvanized steel cable connector with double-layer snap rings, including a connector housing 30, a sheath 10 sleeved on the upper end of the connector housing 30, an outer ring 20 sleeved on the outside of the connector housing 30, and a manganese steel sheet 40 with different diameters installed inside the connector housing 30.

[0026] The connector housing 30 is generally cylindrical with a tapered top and a thicker bottom, including an outer end 31 and an inner end 32. The outer end 31 of the connector housing 30 is provided with an upper outer ring retaining edge 312, a lower outer ring retaining edge 313, and an outer ring mounting part 314. The upper outer ring retaining edge 312 is fixedly connected to the outer ring mounting part 314 by two mutually symmetrical bending connections 311. The upper outer ring retaining edge 312 and the outer ring mounting part 314 are provided with bending clearances 315. The outer ring mounting part 314 is used to install the outer ring 20, and the upper outer ring retaining edge 312 and the lower outer ring retaining edge 313 are used to fix the outer ring 20. The outer side wall of the inner end 32 of the connector housing 30 is provided with an outwardly protruding double-layer retaining spring 321 for installing and fixing the reducing manganese steel sheet 40. The double-layer retaining ring 321 includes a first spring 322 and a second spring 323. The first spring 322 is located in the upper layer and has a round hole in the middle. It has two limiting pieces 324 at the front to limit the manganese steel sheet 40 with different diameters. The second spring 323 is located in the lower layer and also has a round hole in the middle. It also has two limiting pieces 324 at the front, which work together with the limiting pieces 324 of the first spring 322 to better limit the manganese steel sheet 40 with different diameters. The second spring 323 has two bent flanges 325 at the rear to block the manganese steel sheet 40 with different diameters and provide a force point.

[0027] The outer ring 20 has several symmetrically arranged outer ring buckles 21 on its side wall, which are used to engage with the junction box; at the same time, the outer ring 20 has two symmetrically arranged retaining buckles 22 on its side wall, which are used to cooperate with the lower retaining edge 313 of the outer ring to fix the outer ring 20.

[0028] The manganese steel sheet 40 with different capacities is generally inverted U-shaped, including a manganese steel sheet connecting part 41, a small manganese steel sheet 42, and a large manganese steel sheet 43. The connecting part 41 has a central hole. The small manganese steel sheet 42 and the large manganese steel sheet 43 are arranged parallel to each other, with the small manganese steel sheet 42 in front and the large manganese steel sheet 43 behind. Both the small manganese steel sheet 42 and the large manganese steel sheet 43 have two fixing teeth. The manganese steel sheet 40 with different capacities can be fixedly connected to a double-layer retaining spring 321 via the central hole of the connecting part using screws. After being fixedly connected to the double-layer retaining spring 321, the small manganese steel sheet 42 and the large manganese steel sheet 43 are arranged parallel to each other, with the small manganese steel sheet 42 in front and the large manganese steel sheet 43 behind, in a forward-inward orientation. After the cable is inserted, the fixing teeth, under the elastic force of the manganese steel sheet, hold the cable in place, preventing it from being pulled out.

[0029] The sheath 10 is fitted onto the upper end of the connector housing 30, and includes an extension portion 11 and a sleeve portion 12. The sleeve portion 12 is fitted onto the upper end of the connector housing 30, while the extension portion 11 just covers the exposed housing wall, which is used to protect the cable and prevent the cable sheath from being cut.

[0030] In use, the cable is passed through the inner end 32 of the connector housing 30, and the cable is fixed by the manganese steel sheet 40. The outer end 31 is then connected to the junction box through the outer ring 20 to complete the installation. It is very convenient to use.

[0031] The beneficial effects of this utility model are:

[0032] This invention can be connected to a junction box via a snap-fit ​​method, making installation very convenient, greatly improving installation efficiency, and providing some protection for the cable.
