Description

Technical Field

[0001] The present invention relates to the technical field of fabric processing equipment, and in particular to an electrical connection device and fabric processing equipment. Background Art

[0002] As washing machines become more and more versatile, there are more and more washing modes for users to choose from. The traditional human-computer interaction method of selecting washing modes and setting washing times through four or five physical buttons or knobs can no longer meet the needs of modern high-performance washing (drying) machines. Manufacturers integrate touch display control panels into washing machines, carefully design the interactive interface on the display panel, and provide subsequent OTA (Over-The-Air Upgrade) upgrades to meet users' growing needs for a better life, which has become a development trend of modern washing machines.

[0003] The display panel in the washing machine is connected to the PCB (Printed Circuit Board) by an FPC (Flexible Printed Circuit) through a connector to achieve communication between the display and the controller. However, the washing machine is in a high temperature, high humidity and frequent vibration working environment for a long time. Under such working conditions, if the washing machine touch display control panel still uses the traditional flip-top contact FPC connector, the gold conductive layer of the FPC may be gradually worn due to frequent vibration and corrosive environment, causing its contact reliability to be greatly reduced. When poor contact occurs, the display control panel may not receive a stable signal or power supply, resulting in abnormal display, no display or incomplete display. This not only affects the user's operating experience, but may also have a long-term negative impact on the overall performance of the washing machine.

[0004] If an automotive-grade or pin-type FPC connector is used, although it has excellent anti-vibration characteristics, its large size limits its application in compact display panels. In addition, this type of connector requires welding, piercing, etc. to fix the gold conductive layer of the FPC to the plug terminal, and the other side is inserted into the socket on the substrate side. This process involves many complex processes such as bending, locking and retaining the FPC. Not only is the process complicated, but it also requires the use of professional equipment, which increases production costs. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0051] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0052] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0053] like Figures 1 to 6 As shown, an exemplary embodiment of the present invention provides an electrical connection device 100 for electrically connecting an FPC circuit board and a PCB board (not shown in the figure). The PCB board is provided with a first contact terminal (not shown in the figure), and the FPC circuit board 200 is provided with a second contact terminal 210.

[0054] The electrical connection device 100 includes a connector 110 made of insulating material and a pressing assembly 120. The connector 110 is provided with a plurality of connection terminals 111, and the connection terminals 111 are conductive, for example, the connection terminals 111 can be made of a metal material with guiding properties.

[0055] The connecting terminal 111 is provided with a first connecting end 11a and a second connecting end 11b, the first connecting end 11a is arranged on the top wall of the connector 110, and the second connecting end 11b is arranged on the side wall of the connector 110. For example, the connector 110 is a rectangular structure, which has a top wall, a bottom wall and side walls arranged on the four sides of the rectangular structure. That is to say, when the first connecting end 11a is located on the top wall of the connector 110, the second connecting end 11b will pass through part of the structure of the connector 110 and extend from one of the side walls, so that the second connecting end 11b is arranged on the side wall of the connector 110.

[0056] In one example, a plurality of through holes arranged side by side may be provided on the connector 110, one end of the through hole being located on the top wall of the connector 110, and the other end of the through hole being located on the side wall of the connector 110. There are a plurality of connection terminals 111, and they are arranged one-to-one with the plurality of through holes. The arrangement state between the first connection terminal 11a and the second connection terminal 11b can be realized by arranging the connection terminals 111 one-to-one in the plurality of through holes.

[0057] Among them, one of the first connection terminal 11a and the second connection terminal 11b can be used as an input terminal, and the other end can be used as an output terminal. Alternatively, some of the first connection terminals 11a in the plurality of connection terminals 111 can be used as input terminals, and the remaining first connection terminals 11a can be used as output terminals, and some of the second connection terminals 11b in the plurality of connection terminals 111 can be used as output terminals, and the remaining second connection terminals 11b can be used as input terminals.

[0058] The second connection ends 11 b are used to be electrically connected to the first contact terminals of the PCB board. Specifically, the first contact terminals can be welded to the second connection ends 11 b.

[0059] The top wall of the connector 110 is provided with a mounting position for placing the FPC circuit board, so as to realize the electrical connection between the FPC circuit board 200 and the PCB when the multiple second contact terminals 210 on the FPC circuit board 200 are electrically connected to the multiple first connection terminals 11a one by one.

[0060] The pressing assembly 120 includes a pressing plate 121, which can be opened and closed and pressed on the top wall of the connector 110. For example, one end of the pressing plate 121 is hinged on one side of the top wall of the connector 110, and the other end is rotatably connected relative to the hinge position of the pressing plate 121, so that the pressing plate 121 can be rotatably connected to the connector 110 along a circular rotation direction.

[0061] Among them, when the FPC circuit board 200 needs to be electrically connected to the PCB board, the FPC circuit board 200 is placed on the top wall of the connector 110 and placed in the corresponding installation position, so that the multiple second contact terminals 210 of the FPC circuit board 200 face the multiple first connection ends 11a of the connector 110. When the pressure plate 121 is pressed on the top wall of the connector 110, the multiple second contact terminals 210 are pressed one by one on the multiple first connection ends 11a, thereby realizing the electrical connection between the FPC circuit board 200 and the PCB.

[0062] The electrical connection device 100 in this example has a simple structure and can achieve and maintain high connectivity between the FPC circuit board and the PCB board with relatively simple operations, which can effectively improve the user experience and the reliability of the fabric processing equipment.

[0063] like Figures 1 to 6 As shown, in some embodiments, the pressing assembly 120 further includes an elastic member 122 , a fixing rod 123 and a handheld pressing rod 124 .

[0064] The elastic member 122 is sleeved on the fixed rod 123. This sleeve arrangement enables the elastic member 122 to perform corresponding rotational movement with the fixed rod 123 as the rotation axis. That is, when the operator presses the handheld clamping rod 124, the elastic member 122 rotates around the fixed rod 123, so that the pressure plate 121 can be pressed against the top wall of the connector 110.

[0065] One end of the hand-held pressing rod 124 is fixed to one end of the elastic member 122, and the other end of the elastic member 122 is fixedly connected to the pressing plate 121, forming a force transmission chain. When the hand-held pressing rod 124 moves, the elastic member 122 transmits force to the pressing plate 121, thereby realizing the corresponding action of the pressing plate 121, for example, pressing the FPC circuit board 200 against the top wall of the connector 110.

[0066] The fixing rod 123 is arranged on the connector 110, which provides a stable support point for the entire clamping assembly 120, ensures the relative position relationship between the elastic member 122 and the handheld clamping rod 124, and prevents the entire clamping assembly 120 from being offset or shaken during operation.

[0067] The hand-held pressing rod 124 has a first position and a second position. When the hand-held pressing rod 124 is in the first position, the pressing plate 121 releases the electrical connection between the second contact terminal 210 and the first connecting end 11a. This function provides convenience when installing, inspecting or replacing the FPC circuit board 200.

[0068] The operator can conveniently operate the FPC circuit board 200 without worrying about damage to the FPC circuit board 200 or misoperation of other components due to the connection not being released. The operation of releasing the connection can be easily achieved by setting the hand-held clamping rod 124 in the first position, which reflects the rationality and convenience of the design of the entire clamping assembly 120.

[0069] When the hand-held pressing rod 124 is at the second position, the pressing plate 121 is in a pressing state. When the hand-held pressing rod 124 moves from the first position to the second position, the elastic member 122 drives the pressing plate 121 to move obliquely toward the placement position of the FPC circuit board 200 .

[0070] When reaching the second position, the pressing plate 121 can effectively press the relevant components (such as the second contact terminal 210 and the first connection end 11a) on the FPC circuit board 200. This pressing action ensures the stability and reliability of the electrical connection between the second contact terminal 210 and the first connection end 11a. Through the pressing of the pressing plate 121, problems such as poor contact can be prevented, thereby achieving and ensuring high connectivity between the FPC circuit board 200 and the PCB board.

[0071] like Figures 1 to 6 As shown, in some embodiments, when the pressing plate 121 is in the pressing state, the hand-held pressing rod 124 is hidden in the connector 110. This design reflects the effective use of space. There is usually a certain space inside the connector 110, and the hand-held pressing rod 124 is hidden therein, which avoids the hand-held pressing rod 124 from occupying other space outside when in the pressing state, making the external structure of the electrical connection device 100 more concise, and providing more space for the layout of other components in the fabric processing device.

[0072] Furthermore, hiding the hand-held pressing rod 124 in the connector 110 helps to improve the overall aesthetics of the electrical connection device 100 , making the surface of the electrical connection device 100 smoother and simpler.

[0073] In addition, the corresponding misoperation can be prevented. When the pressing plate 121 is in the pressing state, it indicates that the relevant connection has been stably established and there is no need to operate the hand-held pressing rod 124. That is, in the process of the hand-held pressing rod 124 moving from the first position to the second position to make the pressing plate 121 reach the pressing state, the hand-held pressing rod 124 is finally hidden in the connector 110, marking the end of this operation process.

[0074] This hidden design matches the entire operation process, from the handheld clamping rod 124 being in the first position at the beginning of the operation to being hidden in the connector 110 at the end of the operation, making the entire operation process more orderly and standardized, and facilitating the operator's judgment and management of the use status of the electrical connection device 100.

[0075] like Figures 1 to 6 As shown, in some embodiments, the elastic member 122 includes a torsion spring. The torsion spring is sleeved on the fixing rod 123, and the fixing rod 123 serves as the installation position of the torsion spring, which limits the axial movement of the torsion spring and ensures that the torsion spring will not be offset during operation, so that the torsion spring can accurately transmit force during the operation of the hand-held pressing rod 124, thereby completing the function of pressing or releasing the pressing plate 121.

[0076] The first end of the torsion spring is rotatably connected to the pressure plate 121. This rotatable connection mode enables the torsion spring to effectively transmit the torsion force to the pressure plate. When the torsion spring is twisted, the first end of the torsion spring can drive the pressure plate 121 to move accordingly, for example, to cover the top wall of the connector 110 along the oblique direction.

[0077] The second end of the torsion spring is connected to the hand-held clamping rod 124. When the hand-held clamping rod 124 rotates from the first position to the second position, the rotation action of the hand-held clamping rod 124 causes the torsion spring to twist through the connection with the second end of the torsion spring. As the hand-held clamping rod 124 rotates, the torsion spring continues to twist, and the elastic potential energy gradually increases. This increase in elastic potential energy is the energy source for realizing the movement of the pressure plate 121.

[0078] Specifically, the torsion of the torsion spring causes the first end of the torsion spring to change its angle relative to its initial position, thereby pushing the pressing plate 121 to move obliquely toward the placement position of the FPC circuit board 200. This oblique movement is the result of the coordinated work between the torsion spring, the handheld pressing rod 124 and the pressing plate 121, and ultimately the pressing plate 121 reaches a clamped state when the handheld pressing rod 124 is in the second position.

[0079] It should be noted that the torsion spring is a core component for applying pressure in the clamping assembly 120 . The torsion spring can provide an initial preload force so that the pressure plate 121 can maintain a certain clamping force even when the clamping is not completed, thereby ensuring the clamping effect.

[0080] In the specific use process, taking the use of the electrical connection device 100 in a fabric processing device as an example, the fabric processing device may include but is not limited to a washing machine, etc. The torsion spring can also increase the friction between the pressing plate 121 and the FPC circuit board 200 to prevent the loosening problem caused by external force during use. In addition, the torsion spring has a certain elasticity, which can absorb or buffer the external force, reduce the impact of the washing machine vibration on the FPC circuit board 200, and protect the FPC circuit board 200 from being damaged. At the same time, the torsion spring can also make the pressing plate 121 adapt to FPC circuit boards 200 of different thicknesses, thereby improving the flexibility and adaptability of the electrical connection device 100.

[0081] like Figures 1 to 6As shown, in some embodiments, the clamping assembly 120 further includes a fixing plate 125 .

[0082] The fixing plate 125 is disposed on the connector 110, and when the hand-held pressing rod 124 is in the pressing state, the fixing plate 125 fixes the hand-held pressing rod 124 in the connector 110. The hand-held pressing rod 124 has different states during operation, and in the pressing state, the intervention of the fixing plate 125 can ensure that the hand-held pressing rod 124 is stably fixed in the connector 110. That is, through the interaction between the fixing plate 125 and the hand-held pressing rod 124, the movement of the hand-held pressing rod 124 is restricted, thereby ensuring that the pressing state of the pressing plate 121 is maintained.

[0083] When the hand-held clamping rod 124 is not fixed in the clamping state, it may move due to slight external vibration, external force interference or operator's accidental touch. Such movement may cause the clamping force of the clamping plate 121 to change, thereby affecting the stability of the electrical connection between the second contact terminal 210 and the first connection end 11a. The fixing function of the fixing plate 125 can effectively prevent this from happening, ensuring the reliability of the electrical connection between the second contact terminal 210 and the first connection end 11a.

[0084] That is, when the hand-held pressing rod 124 is fixed in the connector 110 by the fixing plate 125, the pressing plate 121 can continuously and stably press the FPC circuit board 200, thereby ensuring the stability of signal transmission between the FPC circuit board 200 and the PCB board, and helping to improve the performance of the fabric processing device. At the same time, this fixing effect can also reduce component wear and failure caused by loose connection, and help to extend the service life of the electrical connection device 100.

[0085] like Figures 1 to 6 As shown, in some embodiments, the pressing assembly 120 further includes an auxiliary rotating rod 126. The auxiliary rotating rod 126 is a folding rod, which is composed of a first rod, a second rod and a third rod connected in sequence.

[0086] The first rod is rotatably connected to the connector 110. This connection mode enables the first rod to rotate relative to the connector 110, allowing the first rod to change its angular position within a certain range. The third rod is rotatably connected to the pressure plate 121, and also enables the third rod to rotate relative to the pressure plate 121. This double-end rotation connection design enables the auxiliary rotation rod 126 to play a bridge and transmission role between the connector 110 and the pressure plate 121.

[0087] Specifically, the first rod and the second rod are perpendicular to each other, the third rod and the second rod are also perpendicular to each other, and the first rod and the third rod are located on opposite sides of the second rod. This perpendicular relationship constructs a stable geometric structure of the auxiliary rotating rod 126.

[0088] The vertical structure makes the force transmission between the rods more efficient and predictable. For example, when a force is applied in a certain direction, due to the existence of the vertical relationship, the force can be transmitted between the rods in a specific direction, reducing the dispersion of force and unnecessary loss. This structure also helps to improve the stability of the auxiliary rotation rod 126 during operation and prevents structural deformation or distortion.

[0089] During the operation of the clamping assembly 120, the auxiliary rotating rod 126 plays an important role in the transmission and conversion of force. When the pressing plate 121 needs to move, whether due to the operation of the hand-held clamping rod 124 or other factors, the auxiliary rotating rod 126 can transfer the force from the connector 110 to the pressing plate 121, and vice versa.

[0090] Furthermore, since the auxiliary rotating rod 126 connects the connector 110 and the pressure plate 121, the auxiliary rotating rod 126 also guides and limits the movement of the pressure plate 121. The movement trajectory of the pressure plate 121 is relatively limited by the geometric structure and rotational connection method of the auxiliary rotating rod 126.

[0091] The pressing plate 121 can only move within the range allowed by the auxiliary rotating rod 126, which helps to ensure that the movement of the pressing plate 121 is accurate and controllable. For example, during the pressing operation, the auxiliary rotating rod 126 can prevent the pressing plate 121 from being excessively tilted or offset, ensuring that the pressing plate 121 can accurately press the FPC circuit board 200 to the installation position, thereby achieving effective control of the connection between the second contact terminal 210 and the first connection end 11a.

[0092] like Figures 1 to 6 As shown, in some embodiments, a first through hole 12a and a second through hole 12b are provided on the top wall of the pressure plate 121. The first through hole 12a is located in the middle position of the pressure plate 121 and is arranged close to the fixing rod 123. Based on this, the force applied by the torsion spring can be relatively evenly distributed on the pressure plate 121, which helps to maintain balance during the movement of the pressure plate 121 and avoid tilting or unstable movement of the pressure plate 121 due to uneven force.

[0093] The two second through holes 12b are located on both sides of the first through hole 12a, and the symmetrical layout helps to evenly share the force from the auxiliary rotating rod 126. When the third rod of the auxiliary rotating rod 126 is rotatably connected in the second through hole 12b, the symmetrical second through holes 12b can keep the force applied by the two auxiliary rotating rods 126 to the pressing plate 121 balanced in the horizontal direction, further ensuring the stability and accuracy of the pressing plate 121 during movement.

[0094] When the hand-held clamping rod 124 is rotated from the first position to the second position, the torsion spring is twisted, and the torsion spring transmits the torsion force to the pressure plate 121 through the rotational connection of the first end of the torsion spring in the first through hole 12a. With the cooperation of the two auxiliary rotating rods 126, the pressure plate 121 is driven to move obliquely toward the placement position of the FPC circuit board 200. This connection method ensures the effective transmission of force, effectively improves the clamping effect of the entire pressure plate 121, and ensures efficient electrical connection between each second contact terminal 210 on the FPC circuit board 200 and the multiple first connection terminals 11a.

[0095] like Figures 1 to 6 As shown, in some embodiments, the mounting position provided on the top wall of the connector 110 is a sinking groove 112 for placing the FPC circuit board 200 , and the opening of the sinking groove 112 is located on the first side wall 11 c of the connector 110 .

[0096] The opening is provided on the first side wall 11c to facilitate the insertion and removal of the FPC circuit board 200. For example, during the assembly process of the electrical connection device 100, the operator can easily place the FPC circuit board 200 into the sinking groove 112 from a specific direction (i.e., the direction of the first side wall 11c), which helps to improve the assembly efficiency. At the same time, the design of the sinking groove 112 also provides a certain protection for the FPC circuit board 200, so that it is partially or completely embedded in the connector 110, reducing the interference of external factors on the FPC circuit board 200.

[0097] The shape and size of the sinking groove 112 can be flexibly designed according to the specifications of the FPC circuit board 200. In addition, the depth and width of the sinking groove 112 can also be flexibly designed according to the specifications of the FPC circuit board 200 to ensure the electrical connectivity between the FPC circuit board 200 and the PCB board.

[0098] Specifically, the first connection end 11a of the connection terminal 111 is arranged in the sinking groove 112, which enables the first connection end 11a to directly contact the FPC circuit board 200 placed in the sinking groove 112, thereby shortening the connection path and reducing the loss of signal transmission.

[0099] The second connection end 11b of the connection terminal 111 passes through the connector 110 and is located on the second side wall 11d of the connector 110. This through-type layout enables the connection terminal 111 to transmit the signal of the FPC circuit board 200 from the sinking groove 112 to the other side of the connector 110 (the second side wall 11d side), realizing the outward or inward transmission of the signal, thereby facilitating the connection with the PCB board.

[0100] The first side wall 11c and the second side wall 11d are arranged on both sides along the length direction of the connector 110, so that the input and output directions of the signal can be reasonably planned, making the entire connection structure more orderly.

[0101] The connector 110 is provided with an installation space 113 communicating with the sinking groove 112 , and the installation space 113 is used to accommodate the pressing assembly 120 . This communicating design enables the pressing assembly 120 to directly act on the FPC circuit board 200 placed in the sinking groove 112 .

[0102] The presence of the installation space 113 provides a suitable placement position for the pressing assembly 120, ensuring that the pressing assembly 120 can accurately press the FPC circuit board 200 during operation. At the same time, the connection with the sinking groove 112 also facilitates the transmission of force between the pressing assembly 120 and the FPC circuit board 200, making the pressing operation more effective.

[0103] like Figures 1 to 6 As shown, in some embodiments, symmetrically arranged U-shaped notches 112a are provided in the sinking groove 112 along both sides of the width direction of the sinking groove 112. The symmetrically arranged U-shaped notches 112a help to evenly share the pressure and force from the pressure plate 121 and the FPC circuit board 200.

[0104] A limiting post 112b is disposed in the U-shaped notch 112a. A limiting protrusion 220 adapted to be connected to the U-shaped notch 112a is disposed on the FPC circuit board 200, and a limiting hole 230 adapted to be connected to the limiting post 112b is disposed in the limiting protrusion 220.

[0105] The limiting column 112b can be adapted and connected with the limiting hole 230 on the FPC circuit board 200 to accurately position the FPC circuit board 200 in the vertical direction, prevent the FPC circuit board 200 from being displaced in the up-and-down direction in the sinking groove 112, and ensure that the FPC circuit board 200 maintains stable contact with the first connection end 11a of the connection terminal 111. At the same time, the limiting column 112b also has a certain limiting effect on the pressing depth of the pressing plate 121, etc., which helps to stabilize the entire pressing assembly 120 during operation.

[0106] The pressing plate 121 is provided with a U-shaped protrusion 1211 adapted to be connected with the U-shaped notch 112a. When the pressing plate 121 is in a clamping state, the U-shaped protrusion 1211 is accommodated in the U-shaped notch 112a to prevent the pressing plate 121 from deflecting in the horizontal direction, ensuring that the pressing plate 121 can accurately clamp the FPC circuit board 200, and increasing the stability of the pressing plate 121 during the pressing process, so that the pressing plate 121 can move along a preset track, thereby improving the accuracy of the clamping operation.

[0107] When the pressing plate 121 is in a pressed state, the limiting column 112b is inserted into the limiting hole 230, thereby limiting the vertical movement of the FPC circuit board 200. The structure is simple, and the FPC circuit board 200 can be stably placed in the sinking groove 112 and maintain good contact with the first connecting end 11a of the connecting terminal 111. The vertical limiting and the horizontal limiting work together to ensure the stable placement of the FPC circuit board 200 in the sinking groove 112, thereby improving the stability and reliability of the entire device.

[0108] like Figures 1 to 6 As shown, in some embodiments, fixed terminals 114 are respectively provided on both side walls of the connector 110 along its width direction, and the fixed terminals 114 are used to be fixedly connected to the PCB board to ensure the uniformity of force applied to the connector 110 when connected to the PCB board, thereby improving the connection strength with the PCB board.

[0109] An exemplary embodiment of the present invention provides a fabric processing device, the fabric processing device includes a display panel, the display panel includes an FPC circuit board 200, a PCB board and an electrical connection device 100 as any of the above embodiments. The FPC circuit board 200 is electrically connected to the PCB board through the electrical connection device 100.
