Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a screw, a connector and an electrical device. Background Art

[0002] At present, the connecting wires in the connector are usually compressed by screws so that the connecting wires abut against the terminals in the connector to achieve electrical conduction between the connecting wires and the conductive terminals. However, although the method of compressing the connecting wires with screws is relatively simple, in actual use, the screws may not be tightened in place. In this case, the connecting wires and the conductive terminals may have poor contact, which may lead to safety accidents. Summary of the invention

[0003] The main purpose of the present invention is to provide a screw, which is intended to ensure that the screw is installed in place to achieve stable compression of the connecting wire in the connector, reduce the possibility of poor contact between the connecting wire and the conductive terminal, and improve the safety of the connector.

[0004] To achieve the above object, the screw proposed in the present invention is applied to a connector, the connector comprising a conductive terminal and a connecting wire abutting against the conductive terminal, the screw is used to compress one end of the connecting wire electrically abutting against the conductive terminal, and the screw comprises:

[0005] Screw;

[0006] a nut connected to one end of the screw; and

[0007] A shearing structure is connected to the nut and can be separated from the nut when subjected to a preset torque.

[0008] The present invention also provides a connector, comprising:

[0009] Mounting seat;

[0010] A conductive terminal, the conductive terminal being disposed on the mounting seat;

[0011] a connecting wire, one end of which is used to abut against the conductive terminal; and

[0012] The screw is the screw as described above, wherein the screw rod in the screw is used to be connected to the mounting seat and to press the end of the connecting wire electrically against the conductive terminal.

[0013] The present invention also provides an electrical device, comprising the connector as described above.

[0014] When the screw of the technical solution of the present invention is used in a connector to electrically press the connecting wire of the connector against one end of the conductive terminal, since a shearing structure is provided on the nut of the screw, the shearing structure can be driven to rotate during the process of tightening the installation screw, thereby driving the screw rod to rotate to tighten the screw. Moreover, when the shearing structure is subsequently subjected to a preset torque, the shearing structure will break under the action of the corresponding shearing force and separate from the nut. In this way, by tightening the screw until the shearing structure and the nut are separated, it can be ensured that the screw is installed in place to achieve stable compression of the connecting wire in the connector, reducing the possibility of poor contact between the connecting wire and the conductive terminal, thereby improving the safety of the connector.

[0031] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0036] A connector is a device that can serve as a bridge between two electrical devices to achieve electrical connection between the two electrical devices. At present, the connecting wires in the connector are usually compressed by screws so that the connecting wires abut against the terminals in the connector to achieve electrical conduction between the connecting wires and the conductive terminals. However, although the method of compressing the connecting wires with screws is relatively simple, in actual use, the screws may not be tightened into place. At this time, the connecting wires and the conductive terminals will have poor contact, which may lead to safety accidents.

[0037] Based on the above considerations, in order to solve the problem that the screws in the current connectors are not able to effectively press the connecting wires and the conductive terminals frequently, resulting in poor contact between the connecting wires and the conductive terminals, which may cause safety accidents, the present application proposes a new type of screw. The screw innovatively provides a shear structure on the nut, and the shear structure is rotated until it breaks and separates from the nut to ensure that the screw is tightened in place to achieve stable and effective compression of the connecting wires, thereby improving the reliability of the contact between the connecting wires and the conductive terminals and improving the safety of the connector.

[0038] In addition, it should be noted that the connector used for the screws proposed in this application can be further applied to electrical devices. Among them, the electrical device can be a communication device, such as an active antenna unit (Active Antenna Unit, referred to as AAU) or a radio frequency (Remote Radio Unit, referred to as RRU), etc. Of course, the electrical device can also be an energy storage device, such as a charging pile, etc. Alternatively, the electrical device can also be a transportation device, such as an electric vehicle, etc. It can be seen that this application does not limit the specific type of electrical device to which the connector is applied.

[0039] Next, the structure of the screw proposed in this application is explained and illustrated by an embodiment. Please refer to Figures 1 to 5, the screw 40 can be applied to the connector 100, and the connector 100 can include a mounting seat 10, a conductive terminal 20, a connecting wire 30 and a screw 40; the conductive terminal 20 can be mounted on the mounting seat 10; one end of the connecting wire 30 can be inserted into the mounting seat 10 and abut against the conductive terminal 20; and the screw 40 can be mounted on the mounting seat 10 and press the end of the connecting wire 30 electrically abutting against the conductive terminal 20. In one embodiment of the present application, the screw 40 includes a screw rod 41, a nut 43 and a shear structure 45. Among them, the nut 43 is connected to one end of the screw rod 41; the shear structure 45 is connected to the nut 43, and the shear structure 45 can be separated from the nut 43 when subjected to a preset torque.

[0040] The screw rod 41 may be provided with threads on the side circumference so as to be threadedly connected with the mounting seat 10 in the connector 100 through the threads. At the same time, after the screw rod 41 is installed on the mounting seat 10, it can also press the end of the connecting wire 30 in the connector 100 that is electrically abutted against the terminal, so that the connecting wire 30 and the conductive terminal 20 are kept in an abutting state.

[0041] The nut 43 can be used as a rotation position after the shear structure 45 is rotated to break, so that the screw 40 can continue to be loosened and tightened through the nut 43 after the shear structure 45 is separated from the nut 43, thereby realizing the reusability of the screw 40. Among them, on the projection surface perpendicular to the axis of the screw 40, the projection of the nut 43 can be circular. At this time, the nut 43 can be provided with a second rotation groove 435 as described below, so as to cooperate with a driving tool such as a screwdriver through the second rotation groove 435. Of course, the projection of the nut 43 can also be non-circular, for example: it can be square or hexagonal. At this time, the nut 43 can cooperate with a driving tool such as a wrench through the side circumference. In addition, the nut 43 and the screw rod 41 can be an integral structure. In this way, the connection strength of the nut 43 and the screw rod 41 at the connection point can be improved, which is conducive to improving the overall strength of the screw 40. At the same time, it also allows the two to be manufactured by integral molding, so as to omit the subsequent assembly process and help improve the production efficiency of the screw 40. Of course, the nut 43 and the screw rod 41 may also be provided in a separate structure, and then assembled together by any connection method such as welding connection or adhesive connection.

[0042] The shear structure 45 can be arranged on the nut 43 and used as a rotation position, so that when the screw 40 is installed and tightened, the tightening operation can be performed through the shear structure 45. At the same time, when the screw 40 is tightened to a certain extent, the torque received by the shear structure 45 reaches the preset torque (the preset torque can be adaptively designed according to the tightening degree required by the screw 40, ensuring that the screw 40 is tightened to the required installation state when the shear structure 45 is subjected to the preset torque), the shear structure 45 will be broken due to the shear force exceeding the bearing limit and separated from the nut 43. At this time, the breaking and separation of the shear structure 45 can give a prompt that the screw 40 is tightened in place, so that the screw 40 can be installed in place during the installation process. In particular, when the connector 100 also includes an outer shell 50 sleeved on the outside of the mounting seat 10, the shear structure 45 will interfere with the outer shell 50 because the shear structure 45 protrudes when it is not broken and separated, so that the outer shell 50 cannot be further sleeved on the outside of the mounting seat 10. That is, at this time, the shear structure 45 can also play a fool-proof role in the installation sequence of the connector 100, so that the assembly can only be completed after the screw 40 is installed and tightened until the shear structure 45 breaks and separates, which is conducive to further improving the effect of ensuring that the screw 40 is installed in place. Among them, the shear structure 45 can include a shear section 451 and a rotating head 458 as described below, and of course it can also include only the shear section 451. In addition, the shear structure 45 and the nut 43 can be set in a split structure and then assembled together, or they can be directly set in an integrated structure.

[0043] When the screw 40 of the technical solution of the present application is applied to the connector 100 to electrically press the connecting wire 30 of the connector 100 against one end of the conductive terminal 20, since a shearing structure 45 is provided on the nut 43 of the screw 40, the shearing structure 45 can be driven to rotate during the process of tightening the screw 40, thereby driving the screw rod 41 to rotate to achieve the tightening of the screw 40. And, when the shearing structure 45 is subjected to a preset torque, the shearing structure 45 will break under the action of the corresponding shearing force and separate from the nut 43. In this way, by tightening the screw 40 until the shearing structure 45 and the nut 43 are separated, it can be ensured that the screw 40 is installed in place to achieve stable compression of the connecting wire 30 in the connector 100, reducing the possibility of poor contact between the connecting wire 30 and the conductive terminal 20, thereby improving the safety of the connector 100.

[0044] Please refer to Figure 5 and Figure 6In one embodiment of the present application, the shearing structure 45 includes a shearing section 451 and a rotating head 458. The shearing section 451 is connected to the side of the nut 43 away from the screw rod 41, and the shearing section 451 can be separated from the nut 43 when subjected to a preset torque; the rotating head 458 is connected to the end of the shearing section 451 away from the nut 43.

[0045] The shearing section 451 can be used to realize the main function of the shearing structure 45, that is, it can break when subjected to a preset torque, thereby realizing the separation of the shearing structure 45 and the nut 43. Among them, on the projection surface perpendicular to the axis of the screw 40, the shearing section 451 can be a columnar structure, of course, it can also be a plate structure, etc. The present application does not limit the structural type and shape of the shearing section 451, and it is sufficient to ensure that the shearing structure 45 can break and separate when subjected to a preset torque. The rotating head 458 can be used as a rotating position so that the tightening operation can be performed through the rotating head 458. Among them, on the projection surface perpendicular to the axis of the screw 40, the projection of the rotating head 458 can be circular. At this time, the rotating head 458 can be provided with a first rotating groove 461 as described below, so as to cooperate with a driving tool such as a screwdriver through the first rotating groove 461. Of course, the projection of the rotating head 458 can also be non-circular, for example: it can be square or hexagonal. At this time, the rotating head 458 can cooperate with a driving tool such as a wrench through the side circumference. In addition, the rotating head 458 and the shearing section 451 may be provided as separate structures and then assembled together, or they may be directly provided as an integrated structure.

[0046] In this embodiment, the shearing structure 45 is configured to include a shearing section 451 and a rotating head 458, so that the rotating head 458 can be used as a rotating position. In this way, when installing and tightening the screw 40, the screw 40 can be driven to rotate more conveniently through the rotating head 458, which is conducive to improving the convenience of using the screw 40.

[0047] Please refer to Figure 5 and Figure 6 In one embodiment of the present application, the shear section 451 includes at least two connecting columns 452, and the at least two connecting columns 452 are spaced apart around the axis of the screw 40; one end of each connecting column 452 is connected to the nut 43, and the other end is connected to the rotating head 458.

[0048] The shearing section 451 includes at least two connecting columns 452, that is, the number of the connecting columns 452 can be two, and of course it can also be three, four or more. At least two connecting columns 452 are spaced around the axis of the screw 40, that is, at least two connecting columns 452 are spaced along the circumference of the nut 43. Among them, the cross section of the connecting column 452 can be circular, and of course it can also be square or rectangular. In addition, one end of the connecting column 452 can be set in a separate structure with the nut 43, and of course it can also be an integral structure with the nut 43. Similarly, the other end of the connecting column 452 can be set in a separate structure with the rotating head 458, and of course it can also be set in an integral structure with the rotating head 458.

[0049] In this embodiment, the shearing section 451 is configured to include at least two connecting columns 452, and is staggered with the axis of the screw 40, so that at least two connecting columns 452 can be subjected to a relatively large torque force, so as to effectively achieve the required breaking and separation of the subsequent shearing section 451. In addition, the shape of the shearing section 451 at this time can also be relatively regular, which can facilitate processing and forming thereof.

[0050] Please refer to Figure 5 and Figure 6 In one embodiment of the present application, the nut 43 is provided with a first plug hole 431 , and one end of the connecting column 452 away from the rotating head 458 is inserted into the first plug hole 431 .

[0051] The first socket 431 can be used to provide an installation position to connect with one end of the connecting column 452. Among them, the first socket 431 can be a through hole structure, and of course it can also be a blind hole structure. The shape of the first socket 431 can be adaptively set according to the shape of the connecting column 452. For example: when the cross-section of the connecting column 452 is set to a circle, the first socket 431 can be correspondingly set to a circle. In addition, the connecting column 452 and the first socket 431 can be set to an interference fit as described below, and of course, an adhesive can be filled in the first socket 431 to achieve an adhesive connection between the connecting column 452 and the nut 43. The present application does not limit the connection method between the connecting column 452 and the first socket 431.

[0052] In this embodiment, by providing the first insertion hole 431 on the nut 43 to realize the installation of the connecting column 452, the installation structure of the connecting column 452 can be simplified, which is conducive to improving the convenience of connecting the connecting column 452 and the nut 43. Moreover, by inserting the connecting column 452 into the first insertion hole 431, the contact area between the connecting column 452 and the nut 43 can be increased, which is conducive to improving the stability of the connection between the connecting column 452 and the nut 43. In addition, this also means that the connecting column 452 and the nut 43 are separately arranged, so that the two can be processed separately and independently, which is conducive to improving the convenience of processing.

[0053] In one embodiment of the present application, the connecting column 452 and the first plug hole 431 are arranged in an interference fit.

[0054] In this embodiment, the connection column 452 and the first insertion hole 431 are set to be interference fit, which can make the connection between the connection column 452 and the nut 43 more stable. On the other hand, it is unnecessary to further set a connection structure between the first insertion hole 431 and the connection column 452, which can simplify the structure of the first insertion hole 431 and the connection column 452, thereby facilitating further improving the convenience of the connection between the connection column 452 and the nut 43.

[0055] Please refer to Figure 6 In one embodiment of the present application, the first insertion hole 431 penetrates two surfaces of the nut 43 facing toward and away from the rotating head 458 .

[0056] The first insertion hole 431 penetrates through the two surfaces of the nut 43, that is, the first insertion hole 431 is a through hole structure. In this way, when the direction parallel to the axis of the screw 40 is defined as the up-down direction and the nut 43 is disposed at the upper end of the screw rod 41, the first insertion hole 431 can penetrate through the upper surface and the lower surface of the nut 43.

[0057] In this embodiment, the first hole 431 is set as a through hole structure, so that there is no need to control the processing depth of the first hole 431, and it can be directly processed from one side of the nut 43 to the other side, which is beneficial to improve the convenience of processing the first hole 431.

[0058] Please refer to Figure 5 and Figure 6 In one embodiment of the present application, the rotating head 458 is provided with a second plug hole 459 , and one end of the connecting column 452 away from the nut 43 is inserted into the second plug hole 459 .

[0059] The second socket 459 can be used to provide an installation position to connect with one end of the connecting column 452. Among them, the second socket 459 can be a through hole structure, and of course it can also be a blind hole structure. The shape of the second socket 459 can be adaptively set according to the shape of the connecting column 452. For example: when the cross-section of the connecting column 452 is set to a circle, the second socket 459 can be set to a circle accordingly. In addition, the connecting column 452 and the second socket 459 can be set to an interference fit as described below, and of course, an adhesive can be filled in the second socket 459 to achieve an adhesive connection between the connecting column 452 and the rotating head 458. The present application does not limit the connection method between the connecting column 452 and the second socket 459. In addition, this also means that the connecting column 452 and the rotating head 458 are set separately, so that the two can be processed separately and independently, which is conducive to improving the convenience of its processing. In particular, when the connecting column 452 and the first socket 431 on the nut 43 introduced above are installed by insertion, the connecting column 452, the nut 43 and the rotating head 458 can be arranged in a split structure so that the three can be processed separately and independently to improve the convenience of their processing.

[0060] In this embodiment, the second plug hole 459 is provided on the rotating head 458 to realize the installation of the connecting column 452, which can simplify the installation structure of the connecting column 452, thereby facilitating the convenience of connecting the connecting column 452 and the rotating head 458. Moreover, by inserting the connecting column 452 into the second plug hole 459, the contact area between the connecting column 452 and the rotating head 458 can be increased, thereby facilitating the stability of the connection between the connecting column 452 and the rotating head 458.

[0061] In one embodiment of the present application, the connecting column 452 and the second plug hole 459 are arranged in an interference fit.

[0062] In this embodiment, the connection column 452 and the second plug hole 459 are set to be interference fit, which can make the connection between the connection column 452 and the rotating head 458 more stable. On the other hand, it is unnecessary to further set a connection structure between the second plug hole 459 and the connection column 452, which can simplify the structure of the second plug hole 459 and the connection column 452, thereby facilitating further improving the convenience of the connection between the connection column 452 and the rotating head 458.

[0063] Please refer to Figure 6 In one embodiment of the present application, the second insertion hole 459 passes through two surfaces of the rotating head 458 facing toward and away from the nut 43 .

[0064] The second insertion hole 459 penetrates the two surfaces of the rotating head 458, that is, the second insertion hole 459 is a through hole structure. In this way, when the direction parallel to the axis of the screw 40 is defined as the up-down direction and the nut 43 is disposed at the upper end of the screw rod 41, the second insertion hole 459 can penetrate the upper surface and the lower surface of the rotating head 458.

[0065] In this embodiment, the second socket 459 is set as a through hole structure, so that there is no need to control the processing depth of the second socket 459, and it can be directly processed from one side of the rotating head 458 to the other side, which is beneficial to improve the convenience of processing the second socket 459.

[0066] Please refer to Figure 7 and Figure 8 In one embodiment of the present application, the shear section 451 and the nut 43 are coaxially arranged, and the cross-sectional area of ​​the connection between the shear section 451 and the nut 43 is smaller than the cross-sectional area of ​​other positions of the shear section 451.

[0067] The cross-sectional area of ​​the connection between the shearing section 451 and the nut 43 is smaller than the cross-sectional area of ​​other positions of the shearing section 451, that is, the shearing section 451 forms a strength weak zone at one end close to the nut 43 relative to other positions of the shearing section 451, and then when the shearing section 451 is subjected to a preset torque, it can break in the strength weak zone. Among them, the shearing section 451 can include a conical section 453 and a constant diameter section 456 as described below, so as to form a strength weak zone at the position where the shearing section 451 is connected to the nut 43. Of course, the shearing section 451 can also only include the conical section 453, and the opposite ends of the conical section 453 are respectively connected to the nut 43 and the rotating head 458. Alternatively, the shearing section 451 only includes the constant diameter section 456, and a groove is provided on the constant diameter section 456 to form a strength weak zone.

[0068] In this embodiment, the shearing section 451 and the nut 43 are arranged to be coaxial, so that the number of the shearing section 451 can be one, thereby simplifying the number of shearing sections 451 and reducing the manufacturing cost. Furthermore, by setting the cross-sectional area of ​​the connection between the shearing section 451 and the nut 43 to be smaller than the cross-sectional area of ​​other positions of the shearing section 451, the subsequent breaking and separation required by the shearing section 451 can be conveniently and effectively achieved.

[0069] Please refer to Figure 7 and Figure 8 In one embodiment of the present application, the shear section 451 includes a conical section 453 and an equal-diameter section 456, and the end of the conical section 453 with a relatively smaller cross-sectional area is connected to the nut 43; one end of the equal-diameter section 456 is connected to an end of the conical section 453 away from the nut 43, and the other end is connected to the rotating head 458.

[0070] The conical section 453, that is, the cross section is reduced from one end to the other end. The constant diameter section 456, that is, the cross section is the same from one end to the other end.

[0071] In this embodiment, the shearing section 451 includes a conical section 453 and a constant diameter section 456, so that the cross section of the shearing section 451 at the position connected to the nut 43 can be relatively small, thereby forming a weak strength area that can break when subjected to a preset torque. At the same time, such a setting also makes the structure of the shearing section 451 more regular, thereby facilitating its processing and forming convenience.

[0072] Please refer to Fig. 9 In one embodiment of the present application, the conical segment 453 is provided with a partition groove 454 to separate the conical segment 453 into at least two sub-segment bodies 456 , and the at least two sub-segment bodies 456 are spaced apart and distributed around the axis of the screw 40 .

[0073] The partition groove 454 may penetrate the side circumference of the tapered section 453 , thereby dividing the tapered section 453 into two, three, four or more sub-segment bodies 456 .

[0074] In this embodiment, by providing the partition groove 454 on the conical section 453 , the strength of the conical section 453 can be reduced, thereby facilitating the conical section 453 to break and separate when subjected to a preset torque.

[0075] In one embodiment of the present application, the shearing section 451 , the nut 43 and the rotating head 458 are arranged in an integrated structure.

[0076] In this embodiment, the shearing section 451, the nut 43 and the rotating head 458 are set as an integrated structure, so that the screw 40 can be manufactured by integrated molding (for example: metal injection molding, die casting molding or machine tool processing molding, etc.), which is conducive to improving the consistency of the processing of the screw 40. At the same time, the subsequent assembly of various components in the screw 40 can also be omitted, which is conducive to reducing the manufacturing cost.

[0077] Please refer to Figure 5 In one embodiment of the present application, a first rotating groove 461 is provided on a side of the rotating head 458 facing away from the nut 43 .

[0078] The first rotating groove 461 can be used to cooperate with a driving tool such as a screwdriver. Among them, the first rotating groove 461 can include a first groove section 462 and a second groove section 463 arranged crosswise as described below. At this time, on the projection surface perpendicular to the axis of the screw 40, the first rotating groove 461 can be in the shape of a cross groove, and can be used to cooperate with a cross screwdriver. Of course, the first rotating groove 461 can also only include the first groove section 462 or the second groove section 463. At this time, on the projection surface perpendicular to the axis of the screw 40, the first rotating groove 461 can be in the shape of a slot, and can be used to cooperate with a slotted screwdriver. Or, on the projection surface perpendicular to the axis of the screw 40, the first rotating groove 461 can also be in a hexagonal shape. At this time, the driving tool can include a rotating head in the shape of a hexagonal prism to cooperate with the first rotating groove 461 in the shape of a hexagon.

[0079] In this embodiment, by providing the first rotating groove 461 on the rotating head 458 , it can better cooperate with a driving tool such as a screwdriver, thereby facilitating driving the screw 40 to perform a tightening operation.

[0080] Please refer to Figure 5 In one embodiment of the present application, the first rotating groove 461 includes a first groove section 462 and a second groove section 463 , and the second groove section 463 and the first groove section 462 are cross-arranged.

[0081] In this embodiment, the first rotation groove 461 includes a first intersecting groove section 462 and a second groove section 463, so that the first rotation groove 461 can be used in conjunction with a cross screwdriver. At this time, the rotation head 458 and the screwdriver have more contact positions, which is conducive to improving the stability of driving the rotation head 458 to rotate. Furthermore, since the cross screwdriver is used to cooperate with the first rotation groove 461 and has a pointed tip, in order to further improve the stability of the cooperation between the cross screwdriver and the first rotation groove 461. Please refer to Figure 8 In one embodiment of the present application, the rotating head 458 may be provided with a third hole body 460, and the third hole body 460 is located at the junction of the second slot section 463 and the first slot section 462. In this way, the tip of the cross screwdriver can be avoided through the third hole body 460, so as to further increase the contact area between the cross screwdriver and the first slot section 462 and the second slot section 463 in the first rotating slot 461, thereby improving the stability of the cooperation between the two. In addition, when the shearing section 451 and the screw 40 are coaxially arranged, in order to improve the convenience of processing and forming the third hole body 460, in one embodiment of the present application, the shearing section 451 may be provided with a second hole body 457, and the second hole body 457 is connected to the third hole body 460. In addition, such a configuration can also reduce the strength of the shearing section 451, so as to facilitate the shearing section 451 to break and separate when subjected to a preset torque.

[0082] Please refer to the figure for reference Figures 10 to 12 In one embodiment of the present application, the screw 40 further includes a protective sleeve 47 . The protective sleeve 47 is a cylindrical structure with at least one end being open. The protective sleeve 47 is at least sleeved on the outer side of the shear structure 45 .

[0083] As the name implies, the protective sleeve 47 can be sleeved on the outside of the shear structure 45 to protect the shear structure 45. Among them, the protective sleeve 47 is a cylindrical structure with at least one end being open, which means that the protective sleeve 47 can be set with only one end being open, so as to be sleeved and installed through the end with the opening. However, it should be noted that when the screw 40 is tightened, the protective sleeve 47 needs to be removed. Of course, the protective sleeve 47 can also be set with openings at both ends. At this time, when the screw 40 is tightened, there is no need to remove the protective sleeve 47, which is conducive to improving the protective effect of the protective sleeve 47 on the shear structure 45. In addition, the protective sleeve 47 is at least sleeved on the outside of the shear structure 45, which means that the protective sleeve 47 can only be sleeved on the outside of the shear structure 45. Of course, the protective sleeve 47 can also be further sleeved on the nut 43, or even on the outside of one end of the screw 41 close to the nut 43, to further improve the protective effect. In addition, it should be noted that the protective sleeve 47 can be an integral structure, and can be a closed structure in the circumferential direction, or an unclosed structure. Of course, the protective sleeve 47 can also be a split structure including at least two arc-shaped shells, so that the protective sleeve 47 is formed by the enclosure and assembly of the at least two arc-shaped shells. In addition, the state of the protective sleeve 47 being sleeved on the outside of the shear structure 45 can be maintained by abutting and limiting the abutment portion 471 as described below, and of course it can also be clamped on the outside of the shear structure 45 by the clamping portion. The present application does not limit the limiting method of the protective sleeve 47 on the shear structure 45. In addition, a protective sleeve 47 can be sleeved on the outside of a shear structure 45, and of course it can also be sleeved on the outside of two adjacent shear structures 45.

[0084] In this embodiment, by providing the protective sleeve 47, on the one hand, the shear structure 45 can be protected to prevent the shear structure 45 from being hit and causing the shear structure 45 to break and separate, thereby facilitating the stability of the shear structure 45. On the other hand, the protective sleeve 47 can also increase the overall height of the screw 40, thereby increasing the possibility of interference with the outer shell 50 in the connector 100 during assembly, thereby improving the foolproof effect on the installation sequence of the connector 100.

[0085] Please refer to Fig.12 and Fig.13In one embodiment of the present application, an abutment portion 471 is provided on the inner side of the protective sleeve 47 , and the abutment portion 471 abuts against the nut 43 and / or the shear structure 45 .

[0086] The abutting portion 471 abuts against the nut 43 and / or the shear structure 45 , that is, the abutting portion 471 may abut only against the nut 43 , or may abut only against the shear structure 45 , or may abut against both the nut 43 and the shear structure 45 .

[0087] In this embodiment, the abutment portion 471 can abut and limit the nut 43 and / or the shear structure 45 so that the protective sleeve 47 can be stably maintained on the outside of the shear structure 45, thereby achieving stable protection of the shear structure 45.

[0088] Please refer to Fig.12 and Fig.13 In one embodiment of the present application, the abutment portion 471 includes a first abutment block 473 and a second abutment block 475. The first abutment block 473 abuts against the side of the shear structure 45 away from the nut 43; the second abutment block 475 abuts against the side of the nut 43 away from the screw rod 41.

[0089] In this embodiment, the abutment portion 471 is configured to include a first abutment block 473 and a second abutment block 475, so that the first abutment block 473 can abut and limit the shear structure 45, and the second abutment block 475 and the nut 43 can abut and limit, which is beneficial to improve the abutment and limiting effect of the abutment portion 471, so as to improve the stability of the installation of the protective sleeve 47.

[0090] Please refer to Fig.12 In one embodiment of the present application, on the projection plane of the axis of the vertical screw 40, the projection of the first abutment block 473 and the projection of the second abutment block 475 can be staggered.

[0091] In this embodiment, the projection of the first abutment block 473 and the projection of the second abutment block 475 can be staggered so that the abutment in the circumferential direction of the screw 40 can be more uniform, so that the protective sleeve 47 can be evenly stressed in the circumferential direction, which is beneficial to further improve the stability of the installation of the protective sleeve 47.

[0092] Please refer to Fig.13 In one embodiment of the present application, on a projection plane perpendicular to the axis of the screw 40 , the projection of the second abutment block 475 and the projection of the shear structure 45 partially overlap.

[0093] In this embodiment, the projection of the second abutment block 475 partially overlaps with the projection of the shear structure 45, so that the rotating head 458 of the shear structure 45 can be located between the first abutment block 473 and the second abutment block 475, thereby reducing the possibility of the protective sleeve 47 detaching from the shear structure 45, which is beneficial to further improve the stability of the installation of the protective sleeve 47.

[0094] Please refer to Fig.12 In one embodiment of the present application, the number of the first abutment blocks 473 is at least two, and the at least two first abutment blocks 473 are spaced apart and distributed around the axis of the screw 40 .

[0095] In this embodiment, the provision of at least two first abutment blocks 473 can increase the stability of the abutment limit, thereby further facilitating the stability of the installation of the protective sleeve 47. Similarly, in one embodiment of the present application, the number of the second abutment blocks 475 is at least two, and the at least two second abutment blocks 475 are spaced apart around the axis of the screw 40.

[0097] In this embodiment, the arrangement of the claw 477 enables the protective sleeve 47 and the mounting seat 10 to have a limiting relationship, which is conducive to further improving the stability of the protective sleeve 47 on the outer side of the shearing mechanism. Figure 2 , Figure 4 , Fig.12 as well as Fig.13 The mounting seat 10 of the connector 100 may be provided with a mounting hole 11, and a mounting portion 13 may be provided in the mounting hole 11 and spaced apart from the hole wall of the mounting hole 11 (the mounting portion 13 may be any structure such as a plate structure, a block structure, a seat structure or a frame structure). In this way, the screw 41 may be threadedly connected to the mounting portion 13, and after passing through the mounting portion 13, it may extend into the insertion port 15 to abut and press the conductive terminal 20 and the connecting wire 30 located in the insertion port 15, and the claw 477 on the protective sleeve 47 may be elastically engaged with the hole wall of the mounting hole 11 near the hole opening of the mounting hole 11 (the elastic engagement, that is, the claw 477 may be engaged with the hole wall of the mounting hole 11 after elastic deformation, and may also be separated from the hole wall of the mounting hole 11 after elastic deformation).

[0098] Please refer to Figure 6 In one embodiment of the present application, a second rotation groove 435 is provided on a side of the nut 43 facing away from the screw rod 41 .

At this time, on the projection surface perpendicular to the axis of the screw 40, the second rotating groove 435 can be in the shape of a cross groove, and can be used to cooperate with a cross screwdriver. Of course, the second rotating groove 435 can also only include the first slot body 437 or the second slot body 439. At this time, on the projection surface perpendicular to the axis of the screw 40, the second rotating groove 435 can be in the shape of a slot, and can be used to cooperate with a slotted screwdriver. Or, on the projection surface perpendicular to the axis of the screw 40, the second rotating groove 435 can also be in a hexagonal shape. At this time, the driving tool can include a rotating head in the shape of a hexagonal prism to cooperate with the second rotating groove 435 in the shape of a hexagon. In addition, when the second rotation groove 435 is in a cross groove shape or a straight groove shape, the shear structure 45 can be provided in the area other than the second rotation groove 435 on the surface of the nut 43 provided with the second rotation groove 435. When the second rotation groove 435 is in a hexagonal shape, the shear structure 45 can be provided in the area other than the second rotation groove 435 on the surface of the nut 43 provided with the second rotation groove 435, and of course can also be provided in the second rotation groove 435.

[0100] In this embodiment, by providing the second rotation groove 435 on the nut 43, it can cooperate well with a driving tool such as a screwdriver, thereby facilitating the screw 40 to be loosened and tightened after the shear structure 45 is broken and separated. That is, the screw 40 can be reused.
