[0033] The invention provides an electrical connector.

[0034] Please refer to Figures 1 to 4In one embodiment of the invention, the electrical connector comprises: a first split component 100, a second split component 200 and a connecting component 300, wherein the first split component 100 comprises a first split member 101 and a first plug-in member 102, the first plug-in member 102 is hinged to one end of the first split member 101, a first connecting hole 400 is provided at one end of the first split member 101 away from the first plug-in member 102, a sliding groove 500 connected to the first connecting hole 400 is provided on the outer wall of the first split member 101; a first plug-in hole 190 for cable plugging is provided at one end of the first plug-in member 102 away from the first split member 101; the second split component 200 comprises a second split member 201 and a second plug-in member 102; Connector 202, one end of the second split component 201 is plugged into and rotated in the first connecting hole 400, and an annular groove 600 is provided on the outer peripheral wall of the second split component 201; one end of the second connector 202 is detachably connected to the second split component 201, and an end of the second connector 202 away from the second split component 201 is provided with a second plugging hole 700 for cable plugging; the connecting component 300 includes a slider 301 and a limiting ring 302, and the slider 301 is slidably connected in the sliding groove 500; the limiting ring 302 is sleeved and threadedly connected to the outer wall of the first split component 101, and when the slider 301 abuts against the inner peripheral wall of the limiting ring 302, the two ends of the slider 301 are respectively located in the sliding groove 500 and the annular groove 600.

[0035] In the invention, two cables to be connected are plugged into the first plug hole 190 and the second plug hole 700 respectively. The second plug connector 202 is connected to the first connector to complete the electrical connection of the two cables. The first split member 101 is rotated so that the first split member 101 rotates compared to the second split member 201, and the slider 301 slides in the annular groove 600. The shape of the electrical connector is changed by the rotation of the first split member 101 and the second split member 201 and the hinge of the first plug connector 102 and the first split member 101, so that the electrical connector can be set in a narrow corner, and the electrical connection of the two cables is achieved, thereby improving the adaptability of the electrical connector.

[0036] Specifically, the first split member 101, the first plug-in member 102, the second split member 201 and the second plug-in member 202 are all cylindrical, and the first split member 101, the second split member 201 and the second plug-in member 202 are all coaxially arranged, and the first connecting hole 400 and the first plug-in hole 190 are coaxial with the second split member 201. A plurality of slide grooves 500 are provided, and the slide grooves 500 are spaced apart around the peripheral wall of the first split member 101. The number of sliders 301 is the same as the number of slide grooves 500 and they are arranged one-to-one; the interval distance between any two adjacent slide grooves 500 is the same.

[0037] In one embodiment, the slide groove 500 is arranged in a search direction away from the second split component 201, and the slider 301 is a trapezoidal block. When the slider 301 moves away from the second split component 201, the outer side walls of the slider 301 are all in contact with the corresponding side walls of the slide groove 500, and the slider 301 is separated from the annular groove 600. When the first split component 101 and the first plug-in component 102 need to be separated, the limit ring 302 is rotated. Since the limit ring 302 is threadedly connected to the first split component 101, the limit ring 302 moves along the axis on the first split component 101, and the limit ring 302 loses the obstruction to the slider 301, and the slider 301 can be separated from the annular groove 600. At this time, the first split component 100 can be separated from the second split component 200.

[0038] Specifically, the area of ​​the slider 301 away from the second split component 201 is larger than the area of ​​the slider close to the second split component 201. When the limiting ring 302 abuts against the slider 301, the side of the slider 301 away from the second split component 201 is in contact with the inner circumferential wall of the limiting ring 302, and the side of the slider 301 facing the second split component 201 is in contact with the bottom of the annular groove 600.

[0039] Please continue to refer to Figures 1 to 4 Furthermore, a placement groove is provided on the inner wall of the limiting ring 302 at one end close to the slider 301, and a magnetic ring 303 is embedded in the placement groove. The magnetic ring 303 is used to absorb the slider 301 from the ring groove 600. When the second split component 200 needs to be separated from the first split component 100, the limiting ring 302 is rotated to move the limiting ring 302. When the magnetic ring 303 is located at the slider 301, the slider 301 is attracted to the magnetic ring 303 under the action of magnetic force, and the slider 301 is separated from the ring groove 600. It is convenient to manually separate the slider 301 from the ring groove 600 to separate the first split component 101 from the second split component 201, thereby improving work efficiency.

[0040] Specifically, when the slider 301 is attracted by the magnetic ring 303 , the side walls of the slider 301 are attached to the slide groove 500 , and the slider 301 is separated from the ring groove 600 .

[0041] Furthermore, the bottom of the placement groove and the inner wall of the limiting ring 302 are transitioned through the guide surface 304, and the guide surface 304 is inclined from the direction away from the first connecting member toward one side of the placement groove. When the first split component 101 and the second stage need to be installed, the magnetic ring 303 is moved to the slider 301, and the slider 301 is located in the slide groove 500. After the second split component 201 is plugged into the first connecting hole 400, the limiting ring 302 is rotated to move the limiting ring 302, and the guide surface 304 gradually approaches the slider 301, and the guide surface 304 contacts the slider 301, and the slider 301 is driven to be inserted into the ring groove 600 under the action of the guide surface 304. It is convenient to manually and quickly install the first split component 100 and the second split component 200, thereby improving work efficiency.

[0042] In one embodiment, the stop ring 302 is threadedly connected to the side of the slide groove 500 close to the first connector 102, and the placement groove is an annular groove 600 and is coaxially opened on the side of the stop ring 302 close to the second connector 202. The guide surface 304 is inclined from the side away from the second split component 201 to the side close to the second connector 202.

[0043] In one embodiment, a second connection hole 800 is provided on a side of the second split component 201 close to the first split component 101; a first conductive column 900 is provided in the first connection hole 400, and the first conductive column 900 is inserted into the second connection hole 800; a first spring 110 is sleeved on the first conductive column 900, and the outer wall of the first spring 110 abuts against the inner wall of the second connection hole 800. The electrical connection between the second split component 201 and the first split component 101 is increased by the first conductive column 900 and the first spring 110, thereby improving the stability of the structure.

[0044] Specifically, the second connection hole 800 is coaxially arranged with the second split part 201, and the first conductive column 900 is coaxially arranged in the first connection hole 400. The diameter of the first conductive column 900 is smaller than the first reed 110, and the first reed 110 is a standard part. The inner wall of the first reed 110 abuts against the outer peripheral wall of the first conductive column 900. The current of the two cables is not only transmitted through the direct connection between the first split part 101 and the second split part 201, but also transmitted through the first reed 110, thereby improving the stability of the connection between the cables.

[0045] Furthermore, the second connection hole 800 is a blind hole, and the second connection hole 800 is coaxially provided with a second conductive column 120, and the second conductive column 120 is passed through and rotatably connected to the first conductive column 900. By plugging the second conductive column 120 with the first conductive column 900, the current can also be transmitted through the second conductive column 120 and the first conductive column 900, further improving the stability of the connection between the cables. And when the first split component 101 and the second split component 201 rotate relative to each other, the first conductive column 900 and the second conductive column 120 are used as the rotating shaft 230, thereby improving the stability of the first split component 101 and the second split component 201 during rotation.

[0046] In one embodiment, the second conductive rod 120 is fixed to the bottom of the second connecting hole 800, and a third connecting hole 130 is opened at one end of the second split component 201 away from the first split component 101; a second plug-in component 202 is provided with an insertion section 140 at one end close to the second split component 201, and the insertion section 140 is inserted into the third connecting hole 130, and a second spring leaf 150 is sleeved on the insertion section 140, and the outer peripheral wall of the second spring leaf 150 abuts against the hole wall of the third connecting hole 130; the second plug-in hole 700 extends into the insertion section 140, the second plug-in hole 700 is a blind hole, and a bolt 160 is passed through the bottom of the second plug-in hole 700, and the bolt 160 is threadedly connected to the bottom of the third connecting hole 130. When connecting the second connector 202 to the second split member 201 , the second spring 150 is inserted into the insertion section 140 , the second spring 150 and the insertion section 140 are inserted into the third connection hole 130 , and the bolt 160 is rotated to complete the connection between the second connector 202 and the second split member 201 .

[0047] Specifically, the second spring piece 150 is generally cylindrical with an open end, and the plug-in section 140 is plugged into the opening of the second spring piece 150, and the plug-in section 140 presses the second spring piece 150 into the third connection hole 130. The bolt 160 is coaxially opened at the bottom of the second plug-in hole 700, and the bolt 160 passes through the second plug-in component 202 and the spring piece and is threadedly connected to the second split component 201. The connection between the second plug-in component 202 and the split component is completed. The second spring piece 150 is used to improve the current effect between the second plug-in component 202 and the second split component 201. Improve the stability of the structure.

[0048] In one embodiment, a first clamping ring 170 and a second clamping ring 180 are respectively disposed in the first plug hole 190 and the second plug hole 700. The edge of the inner wall of the first clamping ring 170 away from the second split member 201 is provided with a first chamfer 171, and the edge of the inner wall of the second clamping ring 180 away from the first split member 101 is provided with a second chamfer 181. When the cables are respectively plugged into the first plug hole 190 or the second plug hole 700, the cables are guided by the first chamfer 171 or the second chamfer 181, so that each cable is conveniently plugged into the first plug hole 190 or the second plug hole 700. After the cables are plugged in, the cables will partially expand. The cables are fastened by the first clamping ring 170 and the second clamping ring 180 to prevent the cables from being separated from the first plug hole 190 and the second plug hole 700.

[0049] Specifically, the first plug hole 190 and the second plug hole 700 are further provided with a third spring 210 and a fourth spring 220, respectively. The two ends of the third spring 210 abut the bottom of the first plug hole 190 and the first snap ring 170, respectively. The outer peripheral wall of the third spring 210 abuts the inner wall of the first plug hole 190, and the inner wall of the third spring 210 is used to abut the cable. The two ends of the fourth spring 220 abut the bottom of the second plug hole 700 and the second snap ring 180, respectively. The outer peripheral wall of the fourth spring 220 abuts the inner wall of the second plug hole 700, and the inner wall of the fourth spring 220 is used to abut the cable. Because the third spring 210 and the fourth spring 220 are both elastic, the third spring 210 and the fourth spring 220 can clamp the cables, further preventing the cables from falling off.

[0050] In one embodiment, a rotating shaft 230 is provided at one end of the first split member 101 close to the first plug-in member 102, the first plug-in member 102 is sleeved and rotatably connected to the rotating shaft 230, one end of the rotating shaft 230 extends out of the first plug-in member 102, and a threaded section is provided on the outer peripheral wall of the end of the rotating shaft 230 extending out of the first plug-in member 102, and a nut 240 is threadedly connected to the threaded section. When the cable needs to be stable in the device, the nut 240 is tightened, and the nut 240 clamps the first split member 101 and the second split member 201. The angle between the first split member 101 and the second split member 201 is fixed to prevent the shaking of the device from causing the angle of the first split member 101 to change compared with the second split member 201.

[0051] Specifically, a rubber ring may be provided between the nut 240 and the first split member 101. In another embodiment, a threaded hole may be provided inside the device, and the threaded end of the shaft 230 may be threadedly connected to the threaded hole to fix the electrical connector inside the device and improve the stability of the structure.

[0052] In one embodiment, the electrical connector is further connected to a bridge wire 250, and the two ends of the bridge wire 250 are respectively connected to the first plug-in connector 102 and the second plug-in connector 202; the bridge wire 250 is also connected to a ground wire 260. When the first split component 100 and the second split component 200 are separated due to force majeure, the electrical connection between the first plug-in connector 102 and the second plug-in connector 202 is achieved through the bridge wire 250, ensuring the transmission of current between the cables and improving the reliability of the electrical connector. In addition, the ground wire 260 can be grounded to avoid short circuit or open circuit.

[0053] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
