[0002] A cable connector is an electrical component that connects cables between devices to transmit electrical energy, data, signals, etc., to achieve functions such as data exchange, remote control, and equipment detection. Simply put, a cable connector acts as a bridge.

[0003] Commonly used cable connectors usually have only one cable connector for connecting two devices. However, in some construction sites, the same control cabinet or controller needs to control multiple identical or different devices. At this time, the one-to-one cable connector has low applicability and is inconvenient for cable connection. In addition, the increase in the number of connected joints makes it more likely for the joints to loosen and fall off. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a connector for cable connection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A connector for cable connection includes a connection disk and a main connector. The connection disk is a disc-shaped structure. The main connector is fixedly arranged at the center of the top of the connection disk. A number of connection pins are evenly arranged inside the main connector. Four auxiliary connectors are evenly arranged on the side wall of the connection disk. The main connector and the four auxiliary connectors are electrically connected through the circuit inside the connection disk.

[0007] Preferably, a groove is provided at the bottom of the connection plate, a rotating seat is rotatably connected in the groove, and a bracket is fixedly installed on the side wall of the bottom of the rotating seat.

[0008] Preferably, the main connector includes an annular connecting block and a heat dissipation groove, an annular connecting block surrounding the connecting pins is fixedly arranged on the top of the connecting disk, and a plurality of heat dissipation grooves are evenly arranged on the outer side wall of the annular connecting block.

[0009] Preferably, two Z-shaped slide grooves are symmetrically provided on the outer side wall of the annular connecting block, a locking groove is provided on the top of the Z-shaped slide groove, and the depth of the Z-shaped slide groove decreases from the bottom to the top.

[0010] Preferably, a sliding ring is slidably connected in the Z-shaped slide groove, the inner diameter of the sliding ring is adapted to the outer diameter of the annular connecting block, the inner wall of the sliding ring is symmetrically provided with sliders slidably connected to the inner wall of the sliding ring, a sealing ring is provided on the outside of the slider, and the slider is adapted to the size of the Z-shaped slide groove.

[0011] Preferably, a rubber airbag is fixedly arranged on the top of the sliding ring, and a hollow cavity is opened inside the sliding ring, and the hollow cavity is communicated with the rubber airbag.

[0012] Preferably, the secondary connecting head includes a fixed seat and a rotating head. Four fixed seats are evenly arranged on the side wall of the connecting disk. A thread is provided at the end of each fixed seat. A rubber inner tube is slidably connected inside each fixed seat. A strip groove is provided at the end of the rubber inner tube away from the connecting disk and the diameter is larger than the diameter of the other side of the rubber inner tube. A hollow rotating head is rotatably connected to the thread.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a connection disk, and the disc-type connection disk integrates multiple auxiliary connectors for input. Each auxiliary connector can be replaced according to the different interfaces of different equipment used on the construction site, thereby meeting the connection requirements of one or more equipment. The main connector of the connection disk outputs a signal to the control cabinet, thereby realizing signal transmission of one or more equipment and exchanging it with the control cabinet only through one main connector, reducing the number of wiring connections of the control cabinet, alleviating the labor intensity of construction personnel, reducing the difficulty of wiring the control cabinet, and reducing the risk of loosening or falling off of joints caused by too many wiring heads.

[0015] The utility model provides a main connector and a sliding ring. Before the main connector is connected to the cable, the sliding ring is at the bottom of the Z-shaped slide groove. At this time, the sliding ring in the storage state is convenient for the connection of the cable. After the cable is connected, the sliding ring is pulled to slide along the Z-shaped slide groove to the top and then the slider is connected to the locking groove, so that the sliding ring can be fixed on the top of the Z-shaped slide groove. At this time, the sliding ring can be used to wrap the cable, so that the cable connection is not easy to loosen. At the same time, the heat dissipation groove is changed from the covering state of the sliding ring to the exposed state. When the main connector is working, the heat generated can be transferred to the outside through the heat dissipation groove to enhance the heat dissipation effect. In the process of the sliding ring moving from the bottom to the top of the Z-shaped slide groove, the slider is squeezed by the Z-shaped slide groove to squeeze the air in the hollow cavity into the rubber airbag, so that the rubber airbag expands, so that the rubber airbag and the connected cable sheath are more closely fitted, thereby enhancing the sealing of the cable connection.

[0016] The utility model provides an auxiliary connector. When the auxiliary connector is connected to the cable, the rotating head is rotated. As the rotation degree of the rotating head deepens, one side of the strip groove of the rubber inner cylinder is compressed and gradually squeezed against the cable outer sheath, so that the connection stability and sealing of the auxiliary connector are guaranteed. Different types of auxiliary connectors can also meet the connection requirements of a variety of different devices, making the connection disk more widely applicable and more convenient to use.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-7A connector for cable connection includes a connection disk 1 and a main connector 4. The connection disk 1 is a disc-shaped structure. The main connector 4 is fixedly arranged at the center of the top of the connection disk 1. Several connection pins 8 are evenly arranged in the main connector 4. Four sub-connectors 11 are evenly arranged on the side wall of the connection disk 1. The main connector 4 is electrically connected to the four sub-connectors 11 through the circuit inside the connection disk 1. The disc-shaped connection disk 1 integrates a plurality of sub-connectors 11 for input. Each sub-connector 11 can be replaced according to different interfaces of different equipment used on the construction site, meeting the connection requirements of one or more equipment. The main connector 4 of the connection disk 1 outputs a signal to the control cabinet, realizing that the signal transmission of one or more equipment is exchanged with the control cabinet only through one main connector 4, reducing the number of wiring in the control cabinet, reducing the labor intensity of construction personnel, reducing the difficulty of wiring in the control cabinet, and reducing the risk of loosening or falling off of the connectors caused by too many wiring heads.

[0027] As a technical optimization solution of the utility model, a groove is provided at the bottom of the connection disk 1, and a rotating seat 2 is rotatably connected in the groove, and a bracket 3 is fixedly installed on the bottom side wall of the rotating seat 2. The bracket 3 is used to be placed on the ground or directly inserted into the ground in a soft construction site to facilitate the positioning of the connection disk 1, and the rotating seat 2 facilitates the rotation of the connection disk 1 after the bracket 3 is positioned, so that the angle of the connection disk 1 can be adjusted at any time, which is convenient for construction personnel to rotate the connection disk 1 according to needs to select an appropriate secondary connector 11.

[0028] As a technical optimization solution of the utility model, the main connector 4 includes an annular connecting block 5 and a heat dissipation groove 6. The top of the connection plate 1 is fixedly provided with an annular connecting block 5 surrounding the connecting pin 8, and the outer side wall of the annular connecting block 5 is evenly provided with a plurality of heat dissipation grooves 6. The connecting pin 8 is used to connect the main connector 4 with the control cabinet.

[0029] As a technical optimization solution of the utility model, two Z-shaped slide grooves 7 are symmetrically opened on the outer wall of the annular connecting block 5, a locking groove 71 is opened on the top of the Z-shaped slide groove 7, and the depth of the Z-shaped slide groove 7 decreases from the bottom to the top. The Z-shaped groove 7 is used for the sliding of the sliding ring 9. Before the main connector 4 is connected to the cable, the sliding ring 9 is at the bottom of the Z-shaped groove 7. At this time, the sliding ring 9 in the stored state is convenient for the access of the cable. When the cable is connected, the sliding ring 9 is pulled to slide to the top along the Z-shaped groove 7 and the slider 10 is inserted into the locking groove 71, so that the sliding ring 9 can be fixed on the top of the Z-shaped groove 7. At this time, the sliding ring 9 can be used to wrap the cable, so that the cable connection is not easy to loosen. At the same time, the heat dissipation groove 6 is changed from the covering state of the sliding ring 9 to the exposed state. When the main connector 4 is working, the heat generated can be transferred to the outside through the heat dissipation groove 6 to enhance the heat dissipation effect. In the process of the sliding ring 9 moving from the bottom to the top of the Z-shaped groove 7, the depth from the bottom to the top of the Z-shaped groove 7 decreases, so that the slider 10 gradually slides inward along the inner wall of the sliding ring 9, and the slider 10 can be squeezed.

[0030] As a technical optimization solution of the utility model, a sliding ring 9 is slidably connected in the Z-shaped slide groove 7, the inner diameter of the sliding ring 9 is adapted to the outer diameter of the annular connection block 5, and a slider 10 slidably connected to the inner wall of the sliding ring 9 is symmetrically arranged on the inner wall of the sliding ring 9, and a sealing ring is arranged on the outer side of the slider 10, and the size of the slider 10 is adapted to the Z-shaped slide groove 7. The sliding ring 9 slides on the annular connection block 5 through the cooperation of the slider 10 and the Z-shaped slide groove 7.

[0031] As a technical optimization solution of the utility model, a rubber airbag 91 is fixedly arranged on the top of the sliding ring 9, and a hollow cavity 92 is opened inside the sliding ring 9, and the hollow cavity 92 is connected to the rubber airbag 91. When the sliding ring 9 moves from the bottom to the top of the Z-shaped slide groove 7, the slider 10 is squeezed by the Z-shaped slide groove 7, and the air in the hollow cavity 92 can be squeezed into the rubber airbag 91. The rubber airbag 91 has ductility and elasticity. The entry of air causes the rubber airbag 91 to expand, which can make the rubber airbag 91 fit better with the connected cable sheath, thereby enhancing the sealing of the cable connection.

[0032] As a technical optimization solution of the utility model, the auxiliary connector 11 includes a fixed seat 12 and a rotating head 16. Four fixed seats 12 are evenly arranged on the side wall of the connection disk 1. A thread 14 is provided at the end of each fixed seat 12. A rubber inner tube 13 is slidably connected inside each fixed seat 12. A strip groove 15 is provided at the end of the rubber inner tube 13 away from the connection disk 1 and has a diameter greater than the diameter of the other side of the rubber inner tube 13. A hollow rotating head 16 is rotatably connected to the thread 14. When the auxiliary connector 11 is connected to the cable, the cable is connected to the pins of the auxiliary connector 11 after passing through the rotating head 16, the rubber inner tube 13 and the fixed seat 12. At this time, the rotating head 16 is rotated. As the rotation degree of the rotating head 16 deepens, one side of the strip groove 15 of the rubber inner tube 13 is compressed and gradually squeezed with the outer skin of the cable, so that the connection stability and sealing of the auxiliary connector 11 are guaranteed. Different types of auxiliary connectors 11 can also meet the connection requirements of a variety of different devices, making the connection disk 1 more applicable and more convenient to use.

[0033] When the utility model is in use, the construction personnel place the bracket 3 on the ground, and then connect the cable of the control cabinet to the connecting pin 8 of the main connector 4. After the cable is connected, the sliding ring 9 is pulled to slide along the Z-shaped slide groove 7 to the top and then the slider 10 is connected to the locking groove 71, so that the sliding ring 9 can be fixed on the top of the Z-shaped slide groove 7. When the sliding ring 9 moves from the bottom to the top of the Z-shaped slide groove 7, the slider 10 is squeezed by the Z-shaped slide groove 7, and the air in the hollow cavity 92 can be squeezed into the rubber airbag 91. The air entering causes the rubber airbag 91 to expand and The cable sheath fits tightly, and then one or more appropriate auxiliary connectors 11 are selected according to actual use needs for connection with other devices. When the auxiliary connector 11 is connected to the cable, the cable is connected to the pins of the auxiliary connector 11 after passing through the rotating head 16, the rubber inner tube 13 and the fixing seat 12. At this time, the rotating head 16 is rotated. As the rotation degree of the rotating head 16 deepens, one side of the strip groove 15 of the rubber inner tube 13 is compressed and gradually squeezed with the cable sheath to complete the connection. During use, the heat generated by the main connector 4 is transferred to the outside from the heat dissipation groove 6.
