Description

Technical Field

[0001] The present invention relates to the technical field of electrical flexible connection, and in particular to a flexible connection structure and a processing technology. Background Art

[0002] Copper foil flexible connection components are widely used in many electrical fields, such as generators, transformers, switches, busbars, and metallurgical industries, and other high-current electrical equipment. It is a key component for achieving flexible conductive connections between devices and has many important functions. On the one hand, it can effectively adjust the installation errors between devices and ensure the accuracy of device connections; on the other hand, it can also play a compensatory role during the operation of the equipment, while providing convenience for experimental operations and equipment maintenance.

[0003] The copper foil flexible connection assembly is mainly composed of a connection end and a copper foil sheet group. Among them, the copper foil sheet group is generally made by stacking multiple layers of copper foil sheets and then pressing and welding the two ends. From the perspective of the length of the copper foil sheets, there are two situations from the inner layer to the outer layer, one is that the length gradually increases, and the other is that the length is exactly the same. Under the condition that the installation distance at both ends is determined, this design will make the copper foil length slightly longer than the installation distance, so that the middle part of the copper foil sheet will naturally bend into an arc shape. The original intention of this design is to facilitate heat dissipation and prevent the copper foil flexible connection from being tensilely deformed, so as to ensure its performance and service life.

[0004] However, when installing copper foil flexible connectors of the same model, their installation distance is not completely fixed, and the equipment will vibrate during operation. These factors combined will cause adjacent copper foil sheets to abut against each other, which brings a series of negative effects. First, the heat dissipation effect is greatly reduced, and the heat cannot be effectively dissipated, which will affect the normal operation of the equipment; secondly, the friction and wear between adjacent copper foil sheets are intensified, which will not only shorten the service life of the copper foil flexible connector, but also may cause its conductive performance to decrease; in addition, the abutment contact between adjacent copper foil sheets will also produce a skin effect, further reducing the superiority of the copper foil flexible connector itself and affecting the stability and safety of the entire electrical system. Summary of the invention

[0005] The invention provides a soft connection structure and a processing technology to solve the problem that the performance of the existing copper foil soft connection is degraded during use.

[0006] A soft connection structure and processing technology of the present invention adopts the following technical solutions:

[0007] A soft connection structure comprises a copper foil, a support frame and a clamping piece.

[0008] There are multiple copper foils, and the thickness, width and length of the multiple copper foils are the same; the ends of the multiple copper foils are fixedly connected at the same time, and a wiring board is provided at the ends of the multiple copper foils that are fixedly connected; in the initial state, two adjacent copper foils are in a state of abutting each other; the support frame includes multiple support bars, and each support bar is used to support one copper foil; in the initial state, the support bar is in a state of being out of contact with the copper foil, and two adjacent support bars do not contact each other, each support bar is wavy, and the degree of wave of each support bar is different; each support bar can be deformed, and the ends of the multiple support bars are fixedly connected, and the multiple support bars can be deformed into a state of being parallel to each other; when the multiple support bars are parallel to each other, the length of the support bar is equal to the length of the copper foil; there are multiple clamping members, and each support bar is provided with multiple clamping members, and the multiple clamping members on each support bar can clamp one copper foil.

[0009] Furthermore, the clamping member includes two clamping rods, which are connected to the support bars. When the multiple support bars are in a state of being parallel to each other, the two clamping rods are in a state of being spaced apart and parallel to each other, and the interval between the two clamping rods is equal to the thickness of the copper foil.

[0010] Furthermore, the two clamping rods are both rotatably connected to the support bar.

[0011] Furthermore, the clamping rod has a connecting end and a contact end, the connecting end is connected to the supporting bar, and the contact end is configured to be in the shape of a pen tip.

[0012] Furthermore, the support frame also includes two connectors, each of which can be slidably connected to a wiring board, and the connectors are connected to multiple support bars at the same time.

[0013] Furthermore, a plug slot is provided on the connector, and the connector can be connected to the wiring board through the plug slot.

[0014] Furthermore, a limit block is provided on the wiring board, and the limit block is used to limit the sliding range of the wiring head on the wiring board.

[0015] Furthermore, each support bar is provided with a plurality of buffer grooves, and each buffer groove is provided corresponding to a clamping member; when each support bar on the support frame supports a copper foil, the buffer grooves on the plurality of support bars are in the same vertical line, and a buffer spring is provided between two buffer grooves of two adjacent support bars and in the same vertical line.

[0016] Furthermore, in the same vertical line, the lengths of two adjacent buffer springs when they are in their original lengths are different.

[0017] A soft connection processing technology, using the above soft connection structure, includes the following steps:

[0018] S1, setting the specifications of the copper foil and fixing the ends of the plurality of copper foils;

[0019] S2, adjusting the plurality of support bars on the support frame to be parallel to each other, and clamping each copper foil on a support bar using a clamp;

[0021] The beneficial effects of the present invention are as follows: a soft connection structure and processing technology of the present invention, wherein the soft connection structure includes copper foil, a support frame and a clamping piece. When preparing the copper foil soft connection structure, firstly, multiple copper foils of the same specification are selected, the ends of the multiple copper foils are fixedly connected, and the wiring board is connected to the ends of the multiple copper foils that are fixedly connected. Then, the multiple support bars on the support frame are adjusted to be parallel to each other, and the copper foil is clamped by using the clamping piece on each support bar so that each support bar supports one copper foil. Then, the support frame is adjusted to restore to the initial state. In the initial state, the multiple support bars on the support frame are in a wavy state, and the degree of wavyness of each support bar is different. When the copper foil is softly connected, the copper foil is connected to the support frame. When the connection structure is installed, the terminal block is connected to the conductive wire. If the distance between the two conductive wires is different from the distance between the two ends of the support bar in the initial state, the support frame is bent at will so that the terminal block and the conductive wire can be smoothly connected. When the support frame is bent, since the support bar is initially in a wavy state, during the bending process of the support frame, the wavy support bar will further increase the degree of the wave along its own wave shape. The support bar drives the copper foil to move synchronously through the clamping part. The support bar is provided to guide the bending of the copper foil to avoid the situation where two adjacent copper foils contact each other when the copper foil is bent, thereby reducing the probability of degradation of the performance of the copper foil soft connection structure due to contact between the copper foils.

[0033] like Figures 1 to 6 As shown, an embodiment of the present invention provides a flexible connection structure, which includes a copper foil 110, a support frame and a clamping member.

[0034] A plurality of copper foils 110 are provided, and the thickness, width and length of the plurality of copper foils 110 are the same. The plurality of copper foils 110 are stacked and placed. In the initial state, two adjacent copper foils 110 are in a state of abutting each other. The plurality of copper foils 110 can be stacked into a rectangular parallelepiped. After the plurality of copper foils 110 are stacked, the copper foil 110 has two ends in the length direction. The two ends in the length direction of the plurality of copper foils 110 are fixedly welded by welding, and the ends of the plurality of copper foils 110 are fixedly connected at the same time. A wiring board 120 is provided at the ends where the plurality of copper foils 110 are fixedly connected. Specifically, two wiring boards 120 are provided, and each wiring board 120 is fixedly connected to one end of the plurality of copper foils 110 stacked into a rectangular parallelepiped. The wiring board 120 is provided with a plurality of wiring holes, and the wiring board 120 can be fixedly connected to the conductive wire.

[0035] The support frame includes a plurality of support bars 130, the plurality of support bars 130 have the same length, the length of each support bar 130 is equal to the length of the copper foil 110, and the two ends of the plurality of support bars 130 are fixedly connected. In the initial state, the support bars 130 are out of contact with the copper foil 110, and two adjacent support bars 130 do not contact each other. Each support bar 130 is wavy, and the degree of wavy of each support bar 130 is different, such as Figure 3 As shown, in the initial state, there is a gap between two adjacent support bars 130, and the gaps between any two adjacent support bars 130 are different. It is easy to understand that the method of preparing the support frame is: first prepare a plurality of support bars 130 of the same length, stack the plurality of support bars 130, and fix the ends of the plurality of support bars 130; apply a horizontal extrusion force to both ends of the plurality of support bars 130, and the extrusion forces are the same in magnitude and opposite in direction. When the two extrusion forces act on the plurality of support bars 130 at the same time, the plurality of support bars 130 are deformed, thereby forming the support frame in the initial state.

[0036] Further, each support bar 130 can be deformed, the ends of the multiple support bars 130 are fixedly connected, the multiple support bars 130 can be deformed into a state parallel to each other, and when the multiple support bars 130 are deformed into a state parallel to each other, the length of each support bar 130 is equal to the length of one copper foil 110, and each support bar 130 is used to support one copper foil 110. When the support bars 130 are used to support the copper foil 110, a deformation force is first applied to the multiple support bars 130 so that the multiple support bars 130 are deformed into a state parallel to each other, and then each support bar 130 is set corresponding to one copper foil 110.

[0037] There are multiple clamping members, and each support bar 130 is provided with multiple clamping members. The multiple clamping members on each support bar 130 can clamp a copper foil 110. Specifically, when using the support bar 130 to support the copper foil 110, a deformation force is first applied to the multiple support bars 130, so that the multiple support bars 130 are deformed into a state parallel to each other, and the clamping members of each support bar 130 are used to clamp a copper foil 110. Subsequently, the force applied to the multiple support bars 130 is canceled, and the multiple support bars 130 reset themselves to the initial state, and the copper foil 110 is deformed into a wavy state.

[0038] A flexible connection structure of the present invention comprises a copper foil 110, a support frame and a clamping piece. When preparing the flexible connection structure of the copper foil 110, firstly, multiple copper foils 110 of the same specification are selected, the ends of the multiple copper foils 110 are fixedly connected, and the wiring board 120 is connected to the ends of the multiple copper foils 110 that are fixedly connected. Then, the multiple support bars 130 on the support frame are adjusted to be parallel to each other, and the clamping piece on each support bar 130 is used to clamp the copper foil 110, so that each support bar 130 supports one copper foil 110. Then, the support frame is adjusted to restore to the initial state. In the initial state, the multiple support bars 130 on the support frame are in a wavy state, and the degree of wavyness of each support bar 130 is different. When the flexible connection structure of the copper foil 110 is installed, The terminal block 120 is connected to the conductive wire. If the distance between the two conductive wires is different from the distance between the two ends of the support bar 130 in the initial state, the support frame is bent at will so that the terminal block 120 and the conductive wire can be smoothly connected. When the support frame is bent, since the support bar 130 is initially in a wavy state, during the bending process of the support frame, the wavy support bar 130 will further increase the degree of the wave along its own wave shape. The support bar 130 drives the copper foil 110 to move synchronously through the clamping member. The support bar 130 is provided to guide the bending of the copper foil 110 to avoid the situation where two adjacent copper foils 110 contact each other when the copper foil 110 is bent, thereby reducing the probability of the performance of the soft connection structure of the copper foil 110 being reduced due to the contact between the copper foils 110.

[0039] In one embodiment, the clamping member includes two clamping rods 140, and the two clamping rods 140 are connected to the support bar 130. When the plurality of support bars 130 are in a state of being parallel to each other, the two clamping rods 140 are in a state of being spaced apart and parallel to each other, and the interval between the two clamping rods 140 is equal to the thickness of the copper foil 110. Specifically, when the copper foil 110 is clamped by the clamping member, a deformation force is first applied to the plurality of support bars 130, so that the plurality of support bars 130 are deformed into a state of being parallel to each other. In one of the clamping members, the copper foil 110 is inserted into the gap between the two clamping rods 140, and the two clamping rods 140 contact the copper foil 110 at the same time; during the resetting process of the support bar 130, the plurality of clamping members on the same support bar 130 carry the copper foil 110 and deform synchronously, so that the copper foil 110 is deformed into a wave shape.

[0040] In one embodiment, both clamping rods 140 are rotatably connected to the support bar 130. Specifically, when the plurality of support bars 130 are deformed to be parallel to each other, the two clamping rods 140 in the same clamping member are in a vertically aligned state. After the copper foil 110 enters the gap between the two clamping rods 140, if the support bar 130 is reset, there is a relative movement between the copper foil 110 and the clamping rod 140. In order to reduce the damage of the clamping rod 140 to the copper foil 110, the clamping rod 140 is rotatably connected to the support bar 130. Then, when the copper foil 110 moves relative to the clamping rod 140, the clamping rod 140 rotates on the support bar 130.

[0041] In one embodiment, the clamping rod 140 has a connecting end and a contact end, the connecting end is connected to the support bar 130, and the contact end is configured to be in the shape of a pen tip. By configuring the contact end to be in the shape of a pen tip, when the copper foil 110 is inserted into the gap between the two clamping rods 140, the pen tip-shaped contact end can guide the copper foil 110, thereby improving the convenience of inserting the copper foil 110 into the gap between the two clamping rods 140.

[0042] In one embodiment, the support frame further includes two connectors 150, each connector 150 can be slidably connected to a wiring board 120, and the connector 150 is simultaneously connected to a plurality of support bars 130. Specifically, when the copper foil 110 is installed on the support bar 130, a deformation force is first applied to the plurality of support bars 130, so that the plurality of support bars 130 are deformed into a state parallel to each other, and then each connector 150 is slidably connected to a wiring board 120, and after each copper foil 110 is clamped by a plurality of clamping members on a support bar 130, when the plurality of support bars 130 are actively reset, each connector 150 slides on a wiring board 120. For example, a slide groove is provided on the wiring board 120, and a slider is provided on the connector 150, and the slider can slide into the slide groove.

[0043] In one embodiment, the connector 150 is provided with a plugging slot 151, and the connector 150 can be connected to the wiring board 120 through the plugging slot 151. Specifically, when the plugging slot 151 is provided on the connector 150, the profile of the connector 150 is slightly U-shaped, and when the plurality of support bars 130 are deformed to be parallel to each other, the connector 150 is connected to the wiring board 120 through the plugging slot 151, and after each copper foil 110 is clamped by the plurality of clamping members on a support bar 130, the plurality of support bars 130 are reset simultaneously, and at the same time, the connector 150 slides on the wiring board 120 through the plugging slot 151.

[0044] In one of the embodiments, a limit block is provided on the terminal block 120, and the limit block is used to limit the sliding range of the terminal head on the terminal block 120. Specifically, two limit blocks are provided, one of which is provided at the end where the terminal block 120 is connected to the copper foil 110, and the other limit block is provided at the end of the terminal block 120 away from the copper foil 110, to ensure that when the connector 150 slides on the terminal block 120, the connector 150 will not be separated from the terminal block 120.

[0045] In one embodiment, each support bar 130 is provided with a plurality of buffer grooves 160, and each buffer groove 160 is provided corresponding to a clamp; when each support bar 130 on the support frame supports a copper foil 110, the buffer grooves 160 on the plurality of support bars 130 are in the same vertical line, and further, when the plurality of support bars 130 on the support frame are in the initial state, each support bar 130 is in a wavy shape, and when each support bar 130 supports a copper foil 110, the buffer grooves 160 on the plurality of support bars 130 form a plurality of vertical lines. A buffer spring 170 is provided between two buffer grooves 160 of two adjacent support bars 130 and in the same vertical line. Furthermore, a connecting block is provided in each buffer groove 160, and a buffer spring 170 is provided on the connecting block between two adjacent support bars 130. When each support bar 130 supports a copper foil 110, if the equipment connected to the soft connection structure of the copper foil 110 has lateral vibration and longitudinal vibration, the deformation of the multiple support bars 130 dissipates energy for the lateral vibration, and the multiple buffer springs 170 dissipate energy for the longitudinal vibration, thereby improving the stability of the soft connection structure of the copper foil 110 during use.

[0046] In one of the embodiments, in the same vertical line, the lengths of two adjacent buffer springs 170 when they are in their original lengths are different. Furthermore, since the wave degrees of two adjacent support bars 130 in the initial state are different, and the distances between two adjacent support bars 130 are different, by setting the initial lengths of multiple buffer springs 170, it is ensured that when the support bars 130 are in their initial state, the buffer springs 170 can all be in their original length state.

[0047] A soft connection processing technology, using a soft connection structure, specifically includes the following steps:

[0048] S1, setting the specifications of the copper foil 110, and fixing the ends of the multiple copper foils 110; two adjacent copper foils 110 are in a state of abutting each other, and the multiple copper foils 110 can be stacked into a rectangular parallelepiped. After the multiple copper foils 110 are stacked, the copper foil 110 has two ends in the length direction. The two ends of the multiple copper foils 110 in the length direction are fixedly welded by welding, and the ends of the multiple copper foils 110 are fixedly connected at the same time.

[0049] S2, adjust the multiple support bars 130 on the support frame to be parallel to each other, and use a clamp to clamp each copper foil 110 on a support bar 130; when using the support bars 130 to support the copper foil 110, first apply a deformation force to the multiple support bars 130 so that the multiple support bars 130 are deformed into a state of being parallel to each other, and then each support bar 130 is set corresponding to a copper foil 110, and a copper foil 110 is clamped by using the clamp of each support bar 130.

[0050] S3, adjusting the plurality of support bars 130 on the support frame to return to the initial state. The clamping member of each support bar 130 clamps a copper foil 110, and then the force applied to the plurality of support bars 130 is canceled, and the plurality of support bars 130 automatically reset to the initial state, and the copper foil 110 is deformed into a wave state.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
