Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In the related art, in order to ensure electrical safety, an access cover is generally correspondingly arranged at the connection position of two conductive structures, for example, the two copper bars are connected as shown in fig. 1, the two copper bars are respectively a first copper bar 11 and a second copper bar 12, the first copper bar 11 and the second copper bar 12 are both arranged in the housing 21, and the first copper bar 11 and the second copper bar 12 are in threaded fit through a first bolt 31 and a nut 32, so that the fixed connection between the first copper bar 11 and the second copper bar 12 is realized. An access opening 21a is formed in the position, corresponding to the connection position of the first copper bar 11 and the second copper bar 12, of the shell 21, and the access opening 21a is sealed through an access cover 21 b. For example, as shown in fig. 1, the access cover 21b is fixedly connected to the housing 21 by the second bolt 33, a seal ring 310 is provided on the periphery of the access opening 21a, and the access cover 21b is pressed against the seal ring 310, so that the access cover 21b and the access opening 21a are sealed, and the number of parts is large, and the structure is complicated.

In the above structure, after the first copper bar 11 and the second copper bar 12 are fixedly connected, the access opening 21a needs to be sealed by the access cover 21 b; and when needing to unpack first copper bar 11 and second copper bar 12 apart, need dismantle second bolt 33 earlier, open access cover 21b, just can further dismantle first bolt 31, and operation process is loaded down with trivial details.

In addition, in order to ensure the operation safety, especially when the first copper bar 11 and the second copper bar 12 need to transmit large current, in order to meet the requirement of high-voltage regulations, the access cover 21b usually needs to be provided with an interlocking harness, so that the power supply lines of the first copper bar 11 and the second copper bar 12 are controlled to be disconnected when the access cover 21b is opened, or some anti-dismounting designs are made on the access cover 21b, for example, the bolt head of the second bolt 33 on the access cover 21b is designed into a non-standard structure, which further increases the complexity of the structure and improves the production cost.

In order to solve the technical problem, the present disclosure provides a connection assembly, detachably connected through a first connection structure and a second connection structure, to realize fixed connection to two conductive structures, the first connection structure has an operation portion exposed outside the partition, and the first connection structure and the two conductive structures are arranged in an insulated manner, while ensuring electrical safety, through operation of the operation portion exposed outside, two conductive structures inside the partition can be fixed or disassembled, the structure is simple, and the disassembly and assembly efficiency is high.

An exemplary embodiment of the present disclosure provides a connection assembly, as shown in fig. 2 and 3, for fixedly connecting two conductive structures 10 located at a first side of a partition 20, the partition 20 may be, for example, an equipment housing, such that the first side of the partition 20 is an inner side of the equipment housing and the second side of the partition 20 is an outer side of the equipment housing. Two conducting structures 10 are for example used for realizing the electricity with two electrical devices and connect, exemplarily, two conducting structures 10 are the copper bar of controller and the copper bar of external connector (for example, the high-voltage plug connector of controller) respectively, or, two conducting structures 10 are the copper bar of controller and the copper bar of electrode respectively, and coupling assembling is used for two copper bar fixed connection.

With continued reference to fig. 2 and 3, the connecting assembly includes a first connecting structure 100 and a second connecting structure 200, wherein the first connecting structure 100 includes an operating part 110 and a connecting part 120 connected to the operating part 110, the operating part 110 is located at a second side of the partitioning member 20, and at least a part of the structure of the connecting part 120 penetrates the first side from the second side of the partitioning member 20. The second connecting structure 200 is located at the first side of the spacer 20, and the second connecting structure 200 is detachably connected with the connecting portion 120 to fixedly connect the two conductive structures 10. The first connecting structure 100 and the two conductive structures 10 are insulated from each other.

In the embodiment, the operation portion 110 of the first connection structure 100 is located at the second side of the partition 20, the connection portion 120 of the first connection structure 100 can penetrate into the first side of the partition 20 through the second side of the partition 20 and can be detachably connected with the second connection structure 200 located at the first side of the partition 20, and since the first connection structure 100 and the two conductive structures 10 are arranged in an insulated manner, an operator can safely operate the operation portion 110. In this way, the operator can detach the connecting portion 120 and the second connecting structure 200 by operating the operating portion 110 without detaching the partition 20, and thus detach and mount the two conductive structures 10. For example, in the embodiment where the partition 20 is a device housing, the operation portion 110 is located at the outer side of the device housing, and the connection portion 120, the second connection structure 200, and the two conductive structures 10 are located at the inner side of the device housing, so that the two conductive structures 10 inside the housing can be attached and detached by operating the operation portion 110 without opening the device housing.

As described above, since the two conductive structures 10 on the first side of the spacer 20 can be disassembled without removing the spacer 20, electrical safety can be ensured, and the disassembling efficiency is improved, in addition, structures such as an access cover are not required to be provided, and an interlocking wire harness is not required to be provided and the anti-disassembling design is not required, the structure is simple, and the production cost is reduced.

It is understood that the term "detachably connected" in this embodiment means that the second connecting structure 200 and the connecting portion 120 can be connected together to fixedly connect the two conductive structures 10, and can also be detached from each other without destroying the structures, so that the two conductive structures 10 can be separated from each other. Illustratively, the detachable connection can be a clamping connection, a screw connection and the like.

The first connecting structure 100 may be a separate structure, an assembly or a structure disposed on the partition 20, and the second connecting structure 200 may be a separate structure, an assembly or a structure disposed on the conductive structure 10. The first connecting structure 100 and the second connecting structure 200 can be connected by a connection manner that can be conveniently detached, such as clamping, screwing and the like. Illustratively, the first connecting structure 100 includes a bolt (not shown), and the second connecting structure 200 includes a threaded hole (not shown) disposed on the two conductive structures 10, and the two conductive structures 10 are fixedly connected by the bolt and the threaded hole. In order to ensure the connection reliability, the bolt is usually made of a metal conductive material, and in order to achieve insulation between the first connection structure 100 and the conductive structure 10, an insulating coating is disposed on the surface of the threaded hole, or an insulating insert is embedded in the conductive structure 10, and a threaded hole matched with the bolt is disposed in the insulating insert.

An exemplary embodiment of the present disclosure provides a connection assembly, as shown in fig. 2 and 3, the connection assembly includes a first connection structure 100 and a second connection structure 200, the first connection structure 100 includes an operation part 110 and a connection part 120 connected to the operation part 110, wherein the connection part 120 includes a first clamping surface 120a located on one side of two conductive structures 10 close to a separator 20, the second connection structure 200 is located on one side of the two conductive structures 10 away from the separator 20, and the second connection structure 200 includes a second clamping surface 200 a. Part of the structure of the connecting portion 120 passes through the two conductive structures 10 and is fixedly connected with the second connecting structure 200, so as to clamp the two conductive structures 10 between the first clamping surface 120a and the second clamping surface 200 a.

In this embodiment, the two conductive structures 10 are fixedly connected by clamping the two conductive structures 10 by the first clamping surface 120a and the second clamping surface 200a, so that reliable contact between the two conductive structures 10 can be ensured, and reliable current transmission between the two conductive structures can be ensured.

In one embodiment, the connecting portion 120 includes a main body rod 121 and an insulating member 122 disposed outside the main body rod 121, the position of the second connecting structure 200 is fixed in the axial direction of the main body rod 121, and a part of the main body rod 121 passes through the two conductive structures 10 and is fixedly connected to the second connecting structure 200. Illustratively, body bar 121 can be coupled by a threaded connection, a snap connection, or the like. For example, the outer side of the end of the main rod 121 is provided with an external thread, the second connecting structure 200 is a nut, and the main rod 121 passes through the two conductive structures 10 and is screwed with the nut. For another example, the end of the main body rod 121 is provided with a claw, the second connecting structure 200 is a clamping hole, and the main body rod 121 passes through the two conductive structures 10 and is clamped and matched with the clamping hole.

With continued reference to fig. 2 and 3, the insulating member 122 is disposed outside the main rod 121, for example, the insulating member 122 is in a cylindrical structure and is sleeved on the main rod 121, and the insulating member 122 may also be in a semi-cylindrical shape or a structure with a plurality of cross sections in a sector ring shape, which is not limited by the present disclosure. The insulating member 122 is made of plastic, ceramic, or other insulating material. The insulating member 122 may be a separate structure from the main body rod 121, for example, the insulating member 122 may be connected to the main body rod 121 by a screw or an interference fit. In this embodiment, a first limiting surface 121a may be disposed on the main body rod 121 to axially limit the insulation member 122. Illustratively, as shown in fig. 4, the main body rod 121 has a stepped shaft, the main body rod 121 includes a first diameter shaft 1211 and a second diameter shaft 1212 connected to each other, a diameter of the first diameter shaft 1211 is greater than a diameter of the second diameter shaft 1212, the first diameter shaft 1211 is connected to the operating portion 110, and the insulating member 122 is sleeved on the second diameter shaft 1212 and is fixedly connected to the second diameter shaft 1212. A stepped surface between the first diametric shaft 1211 and the second diametric shaft 1212 constitutes a first stopper surface 121a, and the insulator 122 abuts against the stepped surface. The insulating member 122 may also be integrally formed with the main body rod 121, for example, the insulating member 122 may be injection molded on the main body rod 121.

In some embodiments, an end surface of the insulating member 122 near one end of the conductive structure 10 forms the first clamping surface 120a, that is, in an assembled state, the insulating member 122 abuts against the conductive structure 10 to ensure an insulating arrangement between the conductive structure 10 and the first clamping surface 120 a.

In other embodiments, as shown in fig. 3, a clamping member 123 is fixedly disposed on the insulating member 122, the insulating member 122 insulates and separates the clamping member 123 from the main rod 121, and the first clamping surface 120a is disposed on the clamping member 123. Since the insulating member 122 insulates and isolates the clamping member 123 from the main body rod 121, the insulating member 122 may select a conductive material with higher hardness to clamp the conductive structure 10, so as to ensure the clamping effect on the conductive structure 10. For example, the material of the clamping member 123 is the same as the material of the conductive structure 10 in contact with the clamping member 123, so that the coefficients of expansion of the clamping member 123 and the conductive structure 10 are the same, and the temperature stress between the clamping member 123 and the conductive structure 10 at high and low temperatures can be reduced, but it is understood that the clamping member 123 may be selected to be a material having a coefficient of expansion close to that of the material of the conductive structure 10. Illustratively, the conductive structure 10 is a copper bar, and the insulating member 122 is made of copper or a material having an expansion coefficient close to that of copper.

In this embodiment, the clamping member 123 and the insulating member 122 may be a separate structure, for example, the clamping member 123 and the insulating member 122 are connected by interference fit, clamping, adhesion, or the like. In this embodiment, a second limiting surface 122a may be provided on the insulating member 122 to axially limit the clamping member 123. Exemplarily, as shown in fig. 3, the clamping member 123 is in a cylindrical structure and is sleeved on the insulating member 122, an annular protrusion 1221 is convexly disposed on an outer side of the insulating member 122, an end surface of the annular protrusion 1221 close to the clamping member 123 forms a second limiting surface 122a, and the clamping member 123 abuts against the end surface of the annular protrusion 1221. The clamping member 123 may also be integrally formed with the insulating member 122, for example, by injection molding the insulating member 122 onto the clamping member 123.

With continued reference to fig. 3, in the assembled state, the insulating member 122 is spaced from the conductive structure 10 by a predetermined distance, i.e., the insulating member 122 is not in contact with the conductive structure 10, so as to ensure reliable contact between the clamping member 123 and the conductive structure 10.

In an exemplary embodiment of the disclosure, as shown in fig. 3, the connecting portion 120 further includes an insulating sleeve 124 sleeved on the main rod 121, the insulating sleeve 124 is an axially-retractable structure, one end of the insulating sleeve 124 is fixedly connected to the insulating member 122, for example, by bonding, interference fit, or the like, and the other end of the insulating sleeve 124 abuts against the second connecting structure 200. The insulating sleeve 124 can further ensure the insulating and isolating effect between the first connecting structure 100 and the conductive structure 10, ensure sufficient creepage distance between the first connecting structure 100 and the conductive structure 10, and ensure the operation safety of the operator.

It is understood that the axially expandable structure described herein means that the dimension of the insulating sleeve 124 in the axial direction can be changed when an external axial force is applied, for example, the insulating sleeve 124 is a corrugated tube of insulating material. In this embodiment, the insulating sleeve 124 which can axially expand and contract is sleeved on the main body rod 121, so that even if the first connecting structure 100 contacts with the conductive structure 10 in the assembling and disassembling process, the arrangement of the insulating sleeve 124 can also ensure electrical safety.

In an embodiment, referring to fig. 6, when the insulating sleeve 124 is in a free state, the other end of the insulating sleeve 124 is flush with the end surface of the main body rod 121 or exceeds the end surface of the main body rod 121, so that the insulating sleeve 124 always insulates and isolates the conductive structure 10 from the main body rod 121 in the process of the main body rod 121 penetrating the conductive structure 10 and being in fit connection with the second connection structure 200, thereby ensuring the operation safety of an operator.

The insulating sleeve 124 may directly abut against the end face of the second connecting structure 200, for example, the insulating sleeve 124 abuts against the second clamping face 200 a. As shown in fig. 3, a slot 210 is disposed on the second connecting structure 200, the slot 210 is formed by recessing the second clamping surface 200a of the second connecting structure 200, so that, in an assembled state, the other end of the insulating sleeve 124 is inserted into the slot 210, and by disposing the slot 210, on one hand, the insulating sleeve 124 can be positioned, so as to ensure that it does not deviate in the radial direction when being extended and retracted, and further ensure the smoothness of the movement of the main rod 121, and on the other hand, ensure that the other end of the insulating sleeve 124 exceeds the second clamping surface 200a, thereby further improving the isolation effect between the main rod 121 and the conductive structure 10.

Illustratively, as shown in fig. 5, a stepped hole 211 is formed in the second connecting structure 200, a large diameter section 211a of the stepped hole 211 penetrates through the second clamping surface 200a, and a small diameter section 211b of the stepped hole 211 is used for being matched and connected with the main body rod 121, so that the large diameter section 211a of the stepped hole 211 constitutes the above-mentioned insertion slot 210. For the convenience of insertion, a guide slope 211c is provided between the large diameter section 211a and the second clamping surface 200a to guide the insertion of the insulating sheath 124.

In one embodiment, the main rod 121 is threaded with the second connecting structure 200, and the second connecting structure 200 is a nut, for example, so that the main rod 121 is gradually screwed into the second connecting structure 200 by rotating the operating part 110. To prevent the second connecting structure 200 from rotating with the main body rod 121, the connecting assembly includes a rotation limiting structure (not shown) for limiting the second connecting structure 200 to rotate around the axis of the main body rod 121. The rotation limiting structure can be, for example, a limiting plate or a limiting sleeve arranged outside the second connection structure 200, or a limiting column or other structure in plug-in fit with the second connection structure 200, as long as the rotation of the second connection structure 200 can be limited, and it is only required to ensure that the main body rod 121 can be smoothly screwed and fixed with the second connection structure 200, and the disclosure does not limit the same.

The second connecting structure 200 may be an insulating material, for example, the second connecting structure 200 is made of insulating material such as ceramic, plastic, etc. The second connecting structure 200 may be formed by providing an insulating layer at a position where it is engaged with the main body bar 121. Illustratively, the second connecting structure 200 includes a body and an insulating layer covering at least a part of a surface of the body, the insulating layer at least covers an end surface of the body near the conductive structure 10, the body may be made of a metal material with high hardness, so as to achieve reliable connection with the main rod 121, and the insulating layer is disposed to effectively ensure insulation and isolation between the conductive structure 10 and the main rod 121.

The following describes the fixing and detaching processes of the connecting assembly to two conductive structures 10 with reference to fig. 6 by taking the connecting assembly shown in fig. 3 as an example.

The main rod 121 penetrates through the partition 20, the insulating member 122 with the clamping member 123 is sleeved on the main rod 121, and then the main rod 121 on the partition 20 is inserted into the two conductive structures 10, and the operating portion 110 exposed on the second side of the clamping member 123 is rotated, so that the main rod 121 is screwed with the second connecting structure 200 until the clamping member 123 and the second connecting structure 200 clamp the two conductive structures 10, thereby completing the fixed connection of the two conductive structures 10.

When it is necessary to disassemble the two conductive structures 10, as shown in fig. 6, the operation portion 110 exposed on the second side of the partition 20 is rotated reversely, so that the main rod 121 is gradually screwed out of the second connecting structure 200, the main rod 121 moves upward continuously, so that the main rod 121 moves out of the two conductive structures 10, and at this time, the two conductive structures 10 can be disassembled.

Illustratively, in the assembled state, the distance between the insulating member 122 and the partition 20 is L1, the distance between the end surface of the main body rod 121 and the surface of the conductive structure 10 close to the partition 20 is L2, and the distance L1 is greater than the distance L2, so as to ensure that the insulating member 122 does not interfere with the partition 20 when the main body rod 121 moves upward.

In one embodiment, the main rod 121 is provided with a first external thread screwed with the insulating member 122 and a second external thread screwed with the second connecting structure 200, and the screwing direction of the first external thread is opposite to the screwing direction of the second external thread, so that even if the main rod 121 is screwed out of the second connecting structure 200, the insulating member 122 is screwed more and more tightly with the main rod 121 even if the insulating member 122 is subjected to the action of torque, thereby ensuring that the insulating member 122 and the main rod 121 are not loosened.

An exemplary embodiment of the present disclosure provides a connection assembly, as shown in fig. 3, including a first connection structure 100 and a second connection structure 200, the first connection structure 100 including an operation part 110 and a connection part 120 connected to the operation part 110. The connecting assembly further includes a sealing structure 300, the sealing structure 300 being disposed between the operating portion 110 and the partition 20, thereby ensuring the sealing performance of the first side of the partition 20 after the connecting assembly fixedly connects the two conductive structures 10. Illustratively, the operating part 110 and the main body rod 121 are formed by bolts, the operating part 110 is a bolt head of the bolt, the main body rod 121 is a screw rod of the bolt, and the sealing structure 300 may be disposed between an end surface of the bolt head opposite to the partition 20 and the partition 20, for example, may be a gasket sleeved on the screw rod. The sealing structure 300 may also be a sealing sleeve, which is sleeved outside the bolt head, and an end surface of the sealing sleeve abuts against the separator 20.
