Description

Technical Field

[0001] The utility model relates to the field of wiring terminals, in particular to a wiring terminal. Background Art

[0002] The oven is one of the equipment used in the drying process of the coating process. Wet coating requires the foil to be coated with positive electrode materials and negative electrode materials. The solvent of the negative electrode material is water, while the solvent of the positive electrode material contains N-methylpyrrolidone (NMP). After drying, it becomes a gas containing NMP. The ignition point of gas NMP is 90°C. It is an explosive chemical substance. When its concentration exceeds 10%, it is prone to spontaneous combustion and is also corrosive.

[0003] The traditional oven drying process utilizes a circulating air system for drying, and the drying efficiency is improved by increasing the drying air volume. If the drying air volume is too large, it is easy to cause the electrode to passively vibrate significantly.

However, the existing infrared heating component installs the electrode by directly punching holes. Due to the thin thickness of the component, direct punching connection is prone to cracks in the substrate, affecting the sealing of the component, and easily allowing NMP gas to enter the inner cavity of the infrared heating component, thereby causing safety hazards.

DETAILED DESCRIPTION

[0036] like Figure 1As shown, Figure 1 It is a schematic diagram of the cross-sectional structure of an infrared heating component in the prior art, which is formed by plating a graphene heating layer 72 on the middle part of one side of a microcrystalline glass substrate 71; plating a conductive layer 73 around the graphene heating layer 72, and the conductive layer 73 is used to connect an external power supply to form a power-on device; and then covering the graphene heating layer 72 and the conductive layer 73 with an insulating layer 74. After the power-on device is energized, the electrode is arranged on the periphery of the graphene heating layer 72, and at this time, the graphene heating layer 72 acts as a heating resistor to provide heat to dry the electrode 61. However, when the above-mentioned infrared heating component is connected to the electrode, the infrared heating component is thin in thickness, and is directly connected to the substrate of the infrared heating component by punching and locking, resulting in holes in the substrate, or cracks in the substrate after punching. At the same time, bolts are usually used to fix the terminals during installation, and holes need to be punched in the housing of the infrared heating device, which can easily reduce its sealing and affect the uniformity of infrared heating. In addition, wiring holes need to be reserved when the electrode wires are connected externally. The wiring holes are directly connected to the inner cavity of the infrared heating equipment. The flammable and explosive gases inside the oven enter the inner cavity of the infrared heating equipment through the wiring holes, which can easily cause safety hazards.

[0037] To this end, an embodiment of the utility model discloses a wiring terminal, which uses a clamping component to press down and fix a connecting component embedded therein, so that the wiring terminal is attached to the surface of the infrared heating component, effectively avoiding the drilling installation of the infrared heating component, thereby solving the technical problem that the existing infrared heating component installs the electrode by direct drilling, and due to the thin thickness of the component, the direct drilling connection is prone to cause cracks in the substrate, affecting the sealing of the component, and easily allowing NMP gas to enter the inner cavity of the infrared heating component, resulting in safety hazards.

[0038] See also Figure 2 , Figure 2 The present invention is a schematic structural diagram of a wiring terminal provided in an embodiment of the present invention.

[0039] In an embodiment of the utility model, a terminal block is provided, comprising a clamping component 1 and a connecting component 2; the clamping component 1 is embedded with the connecting component 2; the connecting component 2 is connected to the wire 3, and the bonding surface is attached to the surface of the infrared heating component to supply energy to the infrared heating component through the wire 3.

[0040] The terminal block refers to an accessory product for realizing electrical connection, which is classified as a connector in the industry and is used to facilitate the connection of the wire 3 to the infrared heating component to provide the electric energy required for heating.

[0041] In this embodiment, the terminal block may include a clamping component 1 and a connecting component 2, wherein the connecting component 2 is embedded in the clamping component 1 and has a bonding surface extending to the outside for adhering to the surface of the infrared heating component. At the same time, the connecting component 2 is connected to the wire 3 inside the clamping component 1, and electrical energy is provided through the wire 3 and transmitted to the infrared heating component through the connecting component 2, so that it can realize the infrared heating function.

[0042] The connection component 2 needs to ensure that sufficient current can pass through it. For this purpose, there is a certain crimping area and close contact between the fitting surface and the conductive position of the infrared heating component. Its material can be a highly conductive metal or a conductive material layer is plated on its surface to effectively transfer electrical energy. The clamping component 1 is used to clamp the connection component 2 on the infrared heating component. In order to avoid accidental touch and melting and loosening caused by the heating of the infrared heating component, it can be made of high-temperature resistant insulating materials such as polyetheretherketone, ceramic materials, etc.

[0043] See also Figure 3 The clamping assembly 1 includes a locking piece 11 and a clamping block 12; a pressing groove 23 is provided at the bottom of the clamping block 12, and the connecting assembly 2 is embedded in the pressing groove 23; a plurality of clamping holes that can be embedded in the locking piece 11 are provided at the top of the clamping block 12, so that the tightness of the connecting assembly 2 can be adjusted through the locking piece 11.

[0044] See also Figure 3 and Figure 4 A plurality of locking members 11 are provided on one side of the pressing block 12, and a pressing groove 23 is provided on the side opposite to the locking member 11. The shape of the pressing groove 23 can match the shape of the connecting component 2 so as to embed the connecting component 2. Since there is a certain crimping area between the fitting surfaces of the connecting component 2 and the infrared heating component, in order to avoid the loosening of the connecting component 2 due to uneven force, a plurality of pressing holes are provided on the pressing block 12 to embed the locking member 11. The locking members 11 are pressed down from different positions respectively, and the tightness of the connecting component 2 is adjusted through the pressing block 12.

[0045] The locking member 11 may be a threaded rod or a screw made of metal or insulating material, and the threaded connection between the locking member 11 and the clamping hole facilitates the adjustment of the tightness of the connection assembly 2 .

[0046] In addition, the clamping components 1 are usually arranged in pairs on the infrared heating components, and holes can be opened on the side of the clamping block 12. Connecting rods are inserted into the holes to fix the position of a group of clamping components 1, thereby further fixing the position of the clamping components 1 on the infrared heating components.

[0047] See also Figure 3The pressing groove 23 includes an access portion 232 and a pressing portion 231 which are interconnected; a wire access hole 25 is provided on the side wall of the access portion 232 for the wire 3 to be accessed; the depth of the pressing portion 231 is less than the depth of the access portion 232.

[0048] In this embodiment, since the connection component 2 needs to be connected to the wire 3 and the infrared heating component at the same time, the wire 3 is connected to the access portion 232 of the pressing groove 23 through the wire access hole 25 opened on the pressing block 12, and the connection between the connection component 2 and the wire 3 is completed in the access portion 232, so its depth needs to be greater than the connected pressing portion 231. The pressing portion 231 does not involve the connection between the components, but presses the connection component 2 downward through the pressing block 12. The groove depth of the pressing portion 231 is less than the access portion 232, so that the connection component 2 can be tightly pressed on the surface of the infrared heating component to ensure good power-on performance.

[0049] like Figure 5 As shown, the connecting component 2 includes a transition part 21 and a docking piece 22; the first end 211 of the transition part 21 is connected to the wire 3, and the second end 212 is movably connected to the docking piece 22; the fitting surface of the docking piece 22 is attached to the surface of the infrared heating component.

[0050] In this embodiment, the adapter 21 includes a first end 211 and a second end 212 opposite to each other. The first end 211 may be in a columnar shape or other shapes that match the cross-sectional shape of the wire 3, and the second end 212 may be in a sheet shape so as to be movably connected to the docking piece 22. The first end 211 of the adapter 21 is detachably connected to the wire 3 connected from the wire access hole 25 to facilitate replacement of the wire 3 connection, and is movably connected to the docking piece 22 through the second end 212, and is attached to the surface of the infrared heating component through the fitting surface of the docking piece 22, and the attachment position is a conductive position of the infrared heating component such as a conductive sheet, a conductive column, etc.

[0051] like Figure 5 As shown, the first end 211 is a columnar structure connected to the wire 3, and the second end 212 is a sheet structure; a connecting hole 24 is provided at the movable connection position between the docking piece 22 and the sheet structure, and is fixed by a connector matching the connecting hole 24.

[0052] In this embodiment, a connecting through hole 24 is provided between the connecting piece 22 and the sheet structure of the second end 212 , and a connecting member such as a screw is passed through the connecting through hole 24 to fix the connecting piece 22 and the adapter 21 .

[0053] In an example of the present invention, the docking piece 22 is bent so as to adjust the tightness of the bonding surface in response to the pressure of the pressing assembly 1 .

[0054] The docking piece 22 is bent, and its bonding surface is bonded to the surface of the infrared heating component. The other folded surface is fixed or movably embedded in the clamping portion 231 of the pressing groove 23 and is provided with a connecting through hole 24. The connecting through hole 24 is located at the access portion 232 of the pressing groove 23 to facilitate connection and fixation with the adapter 21.

[0055] In one example of the present invention, the docking piece 22 is an elastic member, which is further matched with the design of the bent docking piece 22 so that it can have better rebound force, so that the infrared heating component can be pressed and fitted more tightly.

[0056] In an example of the present invention, the surface of the connecting piece 22 is plated with a conductive material layer.

[0057] The conductive material layer can be plated with a highly conductive material, such as copper, silver, gold, or other composite conductive materials, and the skin effect of the conductive metal layer can be used to achieve rapid power-on of the terminal and good conductive performance.

[0058] Optionally, the wiring terminal may further include a fixing component 4 ; the fixing component 4 is installed between the locking member 11 and the pressing block 12 to fix the wiring terminal.

[0059] See also Figure 5 The terminal block may also include an L-shaped fixing component 4, one end of which is provided with a plurality of first through holes adapted to the position of the locking member 11, and the other end of which is provided with a second through hole for connection with an external connecting rod. The fixing component 4 is installed between the locking member 11 and the pressing block 12, and the position of the fixing component 4 is fixed by passing the locking member 11 through the first through hole. Since the infrared heating component can usually be used in equipment such as an oven, the pressing component 1 is fixed to the side wall of the oven through the second through hole to fix the installation position of the terminal block.

[0060] In one example of the present invention, a sealing layer 5 is further provided between the pressing component 1 and the infrared heating component; the shape of the sealing layer 5 matches the bottom surface shape of the pressing component 1.

[0061] In this embodiment, since the docking piece 22 is usually an elastic part, it is easy to break due to excessive pressure from the clamping component 1. A sealing layer 5 can be provided on the clamping component 1 and the infrared heating component. The sealing layer 5 increases the clamping distance between the clamping component 1 and the infrared heating component, thereby improving the sealing of the pressing groove 23 while avoiding breaking of the docking piece 22.

[0062] In addition, in order to further improve the sealing performance of the pressing groove 23, the bottom surface texture of the pressing component 1 and the upper surface texture of the sealing layer 5 can be set as a mating texture, and the lower surface can be set as a smooth texture.

[0063] In an embodiment of the utility model, a terminal block is provided, including a clamping component and a connecting component. A pressing groove is provided in the clamping component and the connecting component is embedded therein, so that the clamping component is connected to the conductive wire in the pressing groove, and the connecting component is attached to the surface of the infrared heating component via the fitting surface of the connecting component to receive the electric energy of the conductive wire to power the infrared heating component, thereby avoiding punching holes in the infrared heating component by connecting the conductive wire in a mosaic manner. At the same time, a clamping component is used, and the locking piece in the clamping component is indirectly contacted and clamped with the connecting component to prevent the locking piece from contacting the surface of the infrared heating component. The terminal block utilizes the clamping component in combination with the bent docking piece to realize the insertion of the electrode into the conductive layer of the infrared heating component, thereby avoiding affecting the structure of the infrared heating component when the terminal block is connected to the infrared heating component, and effectively improving the safety of the infrared heating component.
