[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present invention, unless otherwise clearly stipulated and limited, a first feature being “on” or “below” a second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through another feature between them.

[0034] In addition, the terms “first” and “second” are merely used for distinction in description and have no special meanings.

[0035] like Figure 1-Figure 4 As shown, the present invention provides a multifunctional intermediate joint that can connect cables of different specifications. The multifunctional intermediate joint includes an insulating body 1, a conductor 2, a connecting component 3 and a protective member 4.

[0036] Combination Figure 1 , Figure 4 As shown, the insulating body 1 is, for example, a block structure or a cylindrical structure. Two mounting holes 11 are provided on the insulating body 1, and the two mounting holes 11 are provided on two opposite end faces of the insulating body 1. The conductor 2 is arranged inside the insulating body 1, and the arrangement of the conductor 2 is, for example, as follows: a through hole is provided in the insulating body 1, and the through hole connects the two mounting holes 11, and the conductor 2 can pass through the mounting hole 11 and then be arranged in the through hole.

[0037] like Figure 1As shown, the number of the above-mentioned connecting components 3 is two, and the two connecting components 3 are detachably connected to the above-mentioned two mounting holes 11. In other words, the external dimensions of the two connecting components 3 are adapted to the internal dimensions of the above-mentioned two mounting holes 11, and are detachably arranged in the two mounting holes 11 respectively. The above-mentioned two connecting components 3 are respectively provided with through holes, and the opening direction of the through holes is parallel to the extension direction of the connecting components 3, that is, the center lines of the two through holes are respectively parallel to the center lines of the above-mentioned two mounting holes 11. The two cables located on both sides of the insulating body 1 are respectively inserted into the above-mentioned two through holes to be electrically connected to the above-mentioned conductor 2. The cable includes a conductive core and an insulating sheath covering the conductive core. When connecting, the insulating sheath at the end of the cable is removed to expose the conductive core, and the conductive core is electrically connected to the conductor 2.

[0038] Combination Figure 1 , Figure 2 As shown, the protective member 4 is in the shape of an end cover, for example, the protective member 4 is a hemispherical shell structure. The protective member 4 is detachably connected to the insulating body 1, and is covered at the opening of the mounting hole 11. It can be understood that when the protective member 4 is covered at the opening of the mounting hole 11, the protective member 4 can completely block the mounting hole 11, so as to prevent the fingers of the staff from passing through the mounting opening and accidentally touching the conductor 2 set in the insulating body 1, thereby achieving insulation treatment of one end of the insulating body 1. The connection method between the protective member 4 and the insulating body 1 is as follows: a first connection hole is opened at the end face of one end of the insulating body 1 where the mounting hole 11 is opened, and a second connection hole corresponding to the first connection hole is opened on the protective member 4, and a fastener (such as a bolt) is used to pass through the second connection hole to connect with the first connection hole, so that the protective member 4 can be fixed on the insulating body 1.

[0039] The protective member 4 and the connecting assembly 3 are selectively connected to the insulating body 1. Specifically, when the connecting assembly 3 is removed from the mounting hole 11 of the insulating body 1, the protective member 4 is installed at the opening of the mounting hole 11 corresponding to the removed connecting assembly 3; when the protective member 4 is removed from the opening of the mounting hole 11, the connecting assembly 3 is installed in the mounting hole 11 corresponding to the removed protective member 4.

[0040] The present invention provides a multifunctional intermediate joint that can connect cables of different specifications. The invention provides an insulating body 1 with two mounting holes 11, a conductor 2 is provided in the insulating body 1, and two connecting components 3 that are detachably connected to the two mounting holes 11 are provided. Two cables can be inserted into the through holes provided on the two connecting components 3 to connect with the conductor 2, thereby realizing the circuit conduction between the two cables. In addition, the present application is provided with a protective member 4, which is provided to be detachably connected to the insulating body 1 and covered at the opening of the mounting hole 11, and the protective member 4 and the connecting component 3 are selectively connected to the insulating body 1. Through the above-mentioned arrangement, when it is necessary to temporarily remove the cable on one side of the multifunctional intermediate joint, the cable and the corresponding connecting component can be removed. For example, the removal order is to first remove the cable from the corresponding connecting component 3, and then remove the connecting component 3, and at the same time, the protective member 4 is covered at the opening of the mounting hole 11 corresponding to the connecting component 3 to achieve insulation protection. When it is necessary to continue to connect the cables, the protective member 4 can be removed from the opening of the mounting hole 11, the insulation protection can be removed, and then the cable and the corresponding connection assembly can be installed on the multifunctional intermediate joint. For example, the cable is first passed through the connection assembly 3, and the connection assembly 3 is installed in the mounting hole 11 to achieve the connection of the two cables. In the above operation process, there is no need to simultaneously remove the cable on the other side of the multifunctional intermediate joint, nor is there a need to perform insulation protection on the end of the cable removed from the other side. The insulation protection of the entire multifunctional intermediate joint is achieved only by the protective member 4, which reduces the operation steps and thus improves the efficiency of cable connection.

[0041] like Figure 1 As shown, in some embodiments, the inner diameters of the two mounting holes 11 of the insulating body 1 are the same, the inner diameters of the two perforations are different, and the diameters of the cables on both sides of the insulating body 1 are the same as the inner diameters of the corresponding perforations. It can be understood that the outer diameters of the two connecting components 3 are the same as the inner diameter of the mounting holes 11, and the inner diameters of the perforations opened by the two connecting components 3 are set to be different. After the cables of different diameters are inserted into the two perforations of different inner diameters, the connection of cables of different diameters can be achieved, thereby improving the applicability of the multifunctional intermediate joint. In addition, by further replacing the connecting components 3 with different perforation inner diameters, the multifunctional intermediate joint can be applied to cables of more sizes and specifications, thereby further improving the applicability of the multifunctional intermediate joint.

[0042] Next, combine Figure 1 , Figure 3 , the specific structure of the above-mentioned connecting component 3 is described.

[0043] like Figure 3 As shown, the connection assembly 3 includes a protective cover 32 , a stress cone 33 , an elastic member 34 , a pressing cone 35 and a cable terminal 31 .

[0044] Combination Figure 1 , Figure 3 As shown, the protective cover 32 is detachably mounted at the opening of the mounting hole 11, and a through hole is provided on the protective cover 32 for the cable to pass through. The protective cover 32 is, for example, provided at the opening of the mounting hole 11. Specifically, a third connection hole corresponding to the first connection hole at the end face of the insulating body 1 is provided on the protective cover 32, and a fastener (such as a bolt) is used to pass through the third connection hole to connect with the first connection hole, so that the protective cover 32 can be provided at the opening of the mounting hole 11. Of course, the protective cover 32 can also be directly installed at the opening of the mounting hole 11, for example, the protective cover 32 is clamped at the opening of the mounting hole 11. A sealing gasket is provided at the contact portion between the protective cover 32 and the opening of the mounting hole 11, and the sealing gasket plays an isolating role, so that dust or water vapor from the outside can be prevented from entering the multifunctional intermediate joint through the mounting hole 11, thereby reducing the incidence of power accidents.

[0045] Combination Figure 1 , Figure 3 As shown, the stress cone 33 is arranged in the mounting hole 11, and the stress cone 33 is arranged on the side of the protective cover 32 close to the conductor 2. It can be understood that the outer peripheral surface of the stress cone 33 is adapted to the inner wall of the mounting hole 11, that is, when the outer peripheral surface of the stress cone 33 is inclined (conical), the mounting hole 11 is a conical hole accordingly. The stress cone 33 is arranged between the protective cover 32 and the conductor 2. The stress cone 33 can be sleeved on the cable. By setting the stress cone 33, the cut-off part of the insulation shielding layer of the cable can be extended, thereby improving the electric field distribution of the insulation shielding layer of the cable and ensuring the service life of the cable.

[0046] The elastic member 34 is sleeved on the cable, and is disposed between the stress cone 33 and the protective cover, and the two ends of the elastic member 34 are respectively in contact with the protective cover 32 and the stress cone 33. The elastic member 34 is always in a compressed state, and the elastic member 34 can exert a force on the stress cone 33 that is always in the direction of the conductor 2. The elastic member 34 is, for example, a spring or a spring.

[0047] The cable terminal 31 is arranged close to the conductor 2, and the conductive core at the end of the cable is inserted into the cable terminal 31, so that the cable can be in contact with the conductor 2 through the cable terminal 31. By providing the cable terminal 31, the contact area between the cable and the conductor 2 can be increased, thereby improving the current transmission efficiency.

[0048] In some embodiments, Figure 1As shown, a conductor groove 22 is further provided at one end of the conductor 2 that contacts the cable terminal 31. The conductor groove 22 is communicated with the mounting hole 11. The cable terminal 31 is arranged inside the conductor groove 22, and the outer periphery of the cable terminal 31 abuts against the inner wall of the conductor groove 22. Through the above arrangement, the contact area between the cable terminal 31 and the conductor 2 is increased, and the contact area between the cable and the conductor 2 is indirectly increased, further improving the current transmission efficiency. In other embodiments, the end of the cable terminal abuts against the conductor to achieve electrical connection.

[0049] In one embodiment, the cable is directly connected to the conductor 2. Exemplarily, a cable slot 21 is provided at the connection between the conductor 2 and the cable, the cable slot 21 is communicated with the above-mentioned mounting hole 11, and the cable is plugged into the cable slot 21, so that the connection between the cable and the conductor 2 can be achieved. By using this method to connect the cable to the conductor 2, the outer peripheral surface of the cable can contact the inner side wall of the cable slot 21, thereby increasing the contact area between the cable and the conductor 2 and improving the current transmission efficiency.

[0050] It can be understood that the cable slot 21 described above can be set at the same time as the conductor groove 22. When both are set on the conductor 2 at the same time, the conductor groove 22 is first opened at one end of the conductor 2, and then the cable slot 21 is opened on the bottom wall of the conductor groove 22. In this way, the cable can be plugged into the cable slot 21 and can also be abutted against the conductor 2 through the cable terminal 31, thereby further increasing the contact area between the cable and the conductor 2 and improving the current transmission efficiency.

[0051] Combination Figure 1 , Figure 3 As shown, the compression cone 35 is arranged on the side of the stress cone 33 close to the conductor 2, and the compression cone 35 abuts against the stress cone 33, so that when the elastic member 34 applies a force always toward the direction of the conductor 2 to the stress cone 33, the force can be transmitted to the compression cone 35. The outer surface of the compression cone 35 is inclined (conical), and the compression cone 35 is inserted into the cable terminal 31. The cable can be inserted into the protective cover 32, the elastic member 34, the stress cone 33 and the compression cone 35 in sequence, so that the cable can be connected to the cable terminal 31 through the stress cone 33.

[0052] In the above multifunctional intermediate joint, the connection component 3 is configured as a protective cover 32, a stress cone 33, an elastic member 34, a pressing cone 35 and a cable terminal 31, and the cable can be sequentially inserted into the protective cover 32, the elastic member 34, the stress cone 33 and the pressing cone 35. In this way, after the connection component 3 is installed in the mounting hole 11 and the protective cover 32 is connected to the opening of the mounting hole 11, the protective cover 32 can press the elastic member 34, so that the elastic member 34 applies a force pointing to the conductor 2 to the stress cone 33, and the force can be transmitted to the pressing cone 35. Since the pressing cone 35 is inserted into the cable terminal 31, under the action of the force, the pressing cone 35 can apply a force pointing to the conductor 2 to the cable terminal 31, so that the cable terminal 31 is always in close contact with the conductor 2, ensuring the firmness of the cable connection and preventing the cable connection from being loose or disconnected.

[0053] In some embodiments, in combination Figure 1 , Figure 3 As shown, a bearing ring 36 is further provided between the stress cone 33 and the compression cone 35, and the bearing ring 36 abuts against the stress cone 33 and the compression cone 35 respectively, and the cable is passed through the bearing ring 36. By providing the bearing ring 36 between the stress cone 33 and the compression cone 35, the pressure at the abutment point between the stress cone 33 and the compression cone 35 can be evenly distributed on the bearing ring 36, thereby preventing the stress cone 33 or the compression cone 35 from being worn or damaged due to stress concentration, thereby improving the service life of the multifunctional intermediate joint.

[0054] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, a shielding net 5 is also provided in the insulating body 1, and the shielding net 5 is provided around the two mounting holes 11. It can be understood that when two cables are passed through the mounting holes 11 through the connecting assembly 3 and connected through the conductor 2, the shielding net 5 is provided around the connecting end of the cable and the conductor 2. The multifunctional intermediate joint also includes a shielding wire grounding terminal 6, which is provided on the insulating body 1 and connected to the shielding net 5. By providing the shielding net 5 in the insulating body 1 and providing the shielding wire grounding terminal 6 connected to the shielding net 5, in the actual use process, the grounding wire is connected to the shielding wire grounding terminal 6, which can achieve the function of preventing electromagnetic interference and electromagnetic radiation.

[0055] In some embodiments, Figure 1 As shown, the multifunctional intermediate joint further includes a conductive rod 7, which is arranged on the insulating body 1 and connected to the flange grounding wire 8 of the cable. The flange grounding wire 8 of the cable is used to bridge the static electricity of the cable. After the conductive rod 7 is connected to the flange grounding wire 8 and the conductive rod 7 is grounded, a discharge channel can be provided for the charge, which can eliminate static electricity and prevent the generation of static sparks.

[0056] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
