Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle cable bar installation, and in particular to a flat cable bar fixing device. Background Art

[0002] New energy vehicles refer to all vehicles powered by energy other than gasoline and diesel engines, including pure electric vehicles, fuel cell vehicles, hybrid vehicles, hydrogen-powered vehicles, and solar-powered vehicles. They have relatively low exhaust emissions. Currently, the majority of new energy vehicles sold in the Chinese market are pure electric vehicles and hybrid vehicles.

[0003] With global oil resource scarcity and environmental protection demands, pure electric vehicles and hybrid electric vehicles have become a key trend in modern automotive development. As the power source for pure electric and hybrid vehicles, power battery packs are a key component in their development. Copper busbars and other cables are essential components within power battery packs. Due to their long lengths, copper busbars need to be secured to a base. Copper busbars are flat wires, but securing devices for these are scarce. Traditional cable tie clips are no longer suitable for these types of cables. This is because flat wires are relatively wide and thin, making them difficult to securely secure with traditional cable tie clips. Therefore, there is a need for a convenient, versatile fastener that can secure flat wires effectively, easily install, and remove them, improving installation efficiency. Summary of the Invention

[0004] In view of the above-mentioned shortcomings, the present invention provides a flat cable bar fixing device, which can fix the flat cable bar and can be installed by pressing and fastening the fasteners, which is simple and convenient to install.

[0005] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0006] A flat wire array fixing device is used to fix a flat wire array on an object to be fixed, and the flat wire array fixing device includes:

[0007] A fixing base, used to connect and fix with the object to be fixed, the fixing base is provided with a flat wire row fixing groove, and limiting structures are symmetrically provided on the two opposite side walls of the flat wire row fixing groove;

[0008] The plug-in fastener is detachably connected to the fixed base to fix the flat wire bus in the flat wire bus fixing groove. The plug-in fastener includes at least a main body and two limiting arms extending from the main body. The two limiting arms are symmetrically arranged on both sides of the flat wire bus to be inserted into the limiting structure for buckling connection.

[0009] According to one aspect of the present invention, the limiting structure includes an outwardly convex receiving groove, a self-resetting elastic limiting strip is provided at the bottom of the receiving groove, and a limiting protrusion is provided on the elastic limiting strip.

[0010] According to one aspect of the present invention, the end of the receiving groove is open.

[0011] According to one aspect of the present invention, a limiting step is provided on the outer side of the limiting arm, and the limiting step and the limiting structure are limited.

[0012] According to one aspect of the present invention, the limiting steps are multiple and arranged vertically.

[0013] According to one aspect of the present invention, a buffer is provided on the inner side of the limiting arm.

[0014] According to one aspect of the present invention, ridges are provided on the inner wall of the flat wire array fixing groove.

[0015] According to one aspect of the present invention, the buckle body is connected to the fixed base via a flexible connector.

[0016] According to one aspect of the present invention, the length of the flexible connector is at least sufficient to ensure that the flexible connector is still in a relaxed state or a just tightened state when the limiting arm just leaves the flat wire row fixing groove.

[0017] According to one aspect of the present invention, a connecting piece is provided on the fixed base.

[0018] Advantages of the implementation of the present invention: The flat wire bus fixing device of the present invention is an efficient, stable and easy-to-operate way to fix a flat wire bus. Specifically, the device utilizes the flat wire bus fixing groove and the limiting structure on the fixed base to effectively limit the movement of the flat wire bus in the short side direction, ensuring its stability on the object to be fixed. At the same time, the design of the plug-in fastener enables the user to easily fix the flat wire bus in the fixing groove, and through the buckling connection between the limiting arm and the limiting structure, effectively limits the movement of the flat wire bus in the long side direction, further enhancing the reliability of the fixation. In addition, the application of the flexible connector not only improves the operational flexibility of the device, but also ensures that when the limiting arm is out of the fixing groove, the plug-in fastener is still in a connected state with the fixed base, avoiding the loss of the plug-in fastener, and connecting the fixed base and the plug-in fastener together for easy use. In general, the present invention provides a practical and efficient solution for fixing flat wire bus. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a flat wire array fixing device is used to fix a flat wire array on an object to be fixed, and the flat wire array fixing device includes:

[0028] A fixing base 1 is used to connect and fix to the object to be fixed. The fixing base is provided with a flat wire row fixing groove 11, and limiting structures 12 are symmetrically provided on two opposite side walls of the flat wire row fixing groove;

[0029] The plug-in fastener 2 is detachably connected to the fixed base to fix the flat wire array in the flat wire array fixing groove. The plug-in fastener includes at least a main body 21 and two limiting arms 22 extending from the main body. The two limiting arms are symmetrically arranged on both sides of the flat wire array to be inserted into the limiting structure for buckling connection.

[0030] The fixing base 1 is fixedly connected to the object to be fixed, and the connection method may include various ways, for example, fixedly connected to the object to be fixed by fasteners, and the fasteners may be bolts, screws, rivets and other structures; for example, fixedly connected to the object to be fixed by adhesives; for example, fixedly connected to the object to be fixed by welding, etc.

[0031] The limiting structure includes an outwardly convex receiving groove 121, a self-resetting elastic limiting strip 122 is provided at the bottom of the receiving groove, and a limiting protrusion 123 is provided on the elastic limiting strip. A limiting step 221 is provided on the outer side of the limiting arm, and the limiting step and the limiting structure are limited. Specifically, the limiting step 221 cooperates with the limiting protrusion 123 to limit the position. When in use, pinch the body 21 and insert the two limiting arms 22 into the receiving groove 121. After entering a certain distance, the limiting step 221 contacts the limiting protrusion 123 and squeezes the limiting protrusion outward, causing the elastic limiting strip to expand outward, leaving space for the limiting step to pass through. When the limiting step 221 passes the limiting protrusion 123, the elastic limiting strip is reset and the limiting protrusion 123 returns to its original position, thereby just blocking the limiting step 221 from retreating backward, thereby achieving a snap-on connection limit.

[0032] In practical applications, the end of the receiving groove is an opening 124. The opening allows the front end of the limit arm to pass through the bottom of the receiving groove, which is suitable for fixing narrow flat wire strips. Because the need to fix narrow flat wire strips requires the limit step on the limit arm to be positioned very far back, resulting in extra space at the front end of the limit arm.

[0033] In actual application, a buffer 222 is provided on the inner side of the limiting arm. The provision of the buffer 222 can reduce the contact area between the limiting arm 22 and the flat wire row, and reduce the friction and wear caused by direct hard contact. When the limiting arm 22 is inserted into the accommodating groove 121 and contacts the flat wire row, the exit is larger than the flat wire row, which facilitates the flat wire row to enter the interior of the limiting arm. After that, the buffer 222 can effectively disperse the pressure and protect the flat wire row from damage. At the same time, the material of the buffer 222 is preferably an elastic material, such as rubber or silicone, which can not only provide a good buffering effect, but also ensure a close fit between the limiting arm and the flat wire row, thereby improving the stability and reliability of the connection.

[0034] In practice, the inner wall of the flat cable pack's fixing groove is provided with ridges 111. Ribs 111 are designed to reduce friction between the flat cable pack and the inner wall of the fixing groove, acting as a guide to smoothly guide the flat cable pack into the fixing groove, making the installation process more convenient and efficient. When the flat cable pack is placed in the fixing groove, ridges 111 can fit tightly against the surface of the flat cable pack, effectively preventing the flat cable pack from sliding or shifting within the fixing groove, thereby enhancing the stability of the flat cable pack within the fixing groove.

[0035] In actual application, the fixed base is provided with an adapter (not shown in the figure), and the fixed base is connected and fixed to the object to be fixed through the adapter, and the object to be fixed is provided with a matching connecting card seat, etc. The provision of the adapter increases the flexibility of the installation of the fixed base, so that the fixed base can adapt to more types of objects to be fixed. The design of the connecting card seat ensures the stability of the connection between the fixed base and the object to be fixed, avoiding loosening or falling off during use. Such a structural design not only improves the applicability and stability of the entire wire row fixing device, but also lays a solid foundation for its wide promotion in practical applications.

[0036] One usage of this embodiment is as follows:

[0037] First, fix the fixed base on the object to be fixed, such as on the car sheet metal, and then place the flat wire row flat into the flat wire row fixing groove, then grasp the main body of the fastener, and insert the two limiting arms of the fastener into the accommodating groove. After entering a certain distance, the limiting step contacts the limiting protrusion and squeezes the limiting protrusion outward, causing the elastic limiting strip to expand outward, leaving space for the limiting step to pass through. When the limiting step passes the limiting protrusion, the elastic limiting strip is reset and the limiting protrusion returns to its original position, thereby just blocking the limiting step from withdrawing backward, that is, preventing the limiting arm from withdrawing from the limiting structure, thereby realizing the snap-fit connection and fixation of the fastener and the fixed base, so as to limit and fix the flat wire row in the flat wire row fixing groove of the fixed base.

[0038] Example 2

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a flat wire array fixing device is used to fix a flat wire array on an object to be fixed, and the flat wire array fixing device includes:

[0040] A fixing base 1 is used to connect and fix to the object to be fixed. The fixing base is provided with a flat wire row fixing groove 11, and limiting structures 12 are symmetrically provided on two opposite side walls of the flat wire row fixing groove;

[0041] The plug-in fastener 2 is detachably connected to the fixed base to fix the flat wire array in the flat wire array fixing groove. The plug-in fastener includes at least a main body 21 and two limiting arms 22 extending from the main body. The two limiting arms are symmetrically arranged on both sides of the flat wire array to be inserted into the limiting structure for buckling connection. The plug-in fastener body 21 is connected to the fixed base 1 through a flexible connector 3.

[0042] In practical applications, the length of the flexible connector is at least sufficient to ensure that the flexible connector is still in a relaxed state or a just-tightened state when the limit arm just leaves the flat cable array fixing groove. The flexible connector is a rope connecting the buckle and the fixed base. In practical applications, the flexible connector is an integral, conditional object integrally formed with the buckle and the fixed base.

[0043] The fixing base 1 is fixedly connected to the object to be fixed, and the connection method may include various ways, for example, fixedly connected to the object to be fixed by fasteners, and the fasteners may be bolts, screws, rivets and other structures; for example, fixedly connected to the object to be fixed by adhesives; for example, fixedly connected to the object to be fixed by welding, etc.

[0044] The limiting structure includes an outwardly convex receiving groove 121, a self-resetting elastic limiting strip 122 is provided at the bottom of the receiving groove, and a limiting protrusion 123 is provided on the elastic limiting strip. A limiting step 221 is provided on the outer side of the limiting arm, and the limiting step and the limiting structure are limited. Specifically, the limiting step 221 cooperates with the limiting protrusion 123 to limit the position. When in use, pinch the body 21 and insert the two limiting arms 22 into the receiving groove 121. After entering a certain distance, the limiting step 221 contacts the limiting protrusion 123 and squeezes the limiting protrusion outward, causing the elastic limiting strip to expand outward, leaving space for the limiting step to pass through. When the limiting step 221 passes the limiting protrusion 123, the elastic limiting strip is reset and the limiting protrusion 123 returns to its original position, thereby just blocking the limiting step 221 from retreating backward, thereby achieving a snap-on connection limit.

[0045] In practical applications, the end of the receiving groove is an opening 124. The opening allows the front end of the limit arm to pass through the bottom of the receiving groove, which is suitable for fixing narrow flat wire strips. Because the need to fix narrow flat wire strips requires the limit step on the limit arm to be positioned very far back, resulting in extra space at the front end of the limit arm.

[0046] In actual application, a buffer 222 is provided on the inner side of the limiting arm. The provision of the buffer 222 can reduce the contact area between the limiting arm 22 and the flat wire row, and reduce the friction and wear caused by direct hard contact. When the limiting arm 22 is inserted into the accommodating groove 121 and contacts the flat wire row, the exit is larger than the flat wire row, which facilitates the flat wire row to enter the interior of the limiting arm. After that, the buffer 222 can effectively disperse the pressure and protect the flat wire row from damage. At the same time, the material of the buffer 222 is preferably an elastic material, such as rubber or silicone, which can not only provide a good buffering effect, but also ensure a close fit between the limiting arm and the flat wire row, thereby improving the stability and reliability of the connection.

[0047] In practice, the inner wall of the flat cable pack's fixing groove is provided with ridges 111. Ribs 111 are designed to reduce friction between the flat cable pack and the inner wall of the fixing groove, acting as a guide to smoothly guide the flat cable pack into the fixing groove, making the installation process more convenient and efficient. When the flat cable pack is placed in the fixing groove, ridges 111 can fit tightly against the surface of the flat cable pack, effectively preventing the flat cable pack from sliding or shifting within the fixing groove, thereby enhancing the stability of the flat cable pack within the fixing groove.

[0048] In actual applications, the fixed base is provided with an adapter (not shown in the figure), and the fixed base is connected and fixed to the object to be fixed through the adapter, and the object to be fixed is provided with a matching connecting socket, etc. The provision of the adapter increases the flexibility of the installation of the fixed base, so that the fixed base can adapt to more types of objects to be fixed. The design of the connecting socket ensures the stability of the connection between the fixed base and the object to be fixed, and avoids loosening or falling off during use. Such a structural design not only improves the applicability and stability of the entire wire row fixing device, but also lays a solid foundation for its wide promotion in practical applications. Furthermore, the fixed base can be connected and fixed to the object to be fixed through the adapter, and the design of the adapter makes the connection method of the fixed base more flexible and diverse. The adapter can be a connector such as a bolt, a nut, a buckle, etc. According to the different shapes and structures of the object to be fixed, a suitable adapter is selected for connection. For example, when the object to be fixed is a metal plate with threaded holes, bolts and nuts can be used to secure the fixing base to the metal plate. When the object to be fixed is a smooth surface, connectors such as snaps can be used to securely connect the fixing base to the object to be fixed. The use of adapters greatly enhances the applicability and installation convenience of the flat cable bar fixing device.

[0049] One usage of this embodiment is as follows:

[0050] First, fix the fixed base on the object to be fixed, such as on the car sheet metal, and then place the flat wire row flat into the flat wire row fixing groove, then grasp the main body of the fastener, and insert the two limiting arms of the fastener into the accommodating groove. After entering a certain distance, the limiting step contacts the limiting protrusion and squeezes the limiting protrusion outward, causing the elastic limiting strip to expand outward, leaving space for the limiting step to pass through. When the limiting step passes the limiting protrusion, the elastic limiting strip is reset and the limiting protrusion returns to its original position, thereby just blocking the limiting step from withdrawing backward, that is, preventing the limiting arm from withdrawing from the limiting structure, thereby realizing the snap-fit connection and fixation of the fastener and the fixed base, so as to limit and fix the flat wire row in the flat wire row fixing groove of the fixed base.

[0051] Example 3

[0052] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a flat wire array fixing device is used to fix a flat wire array on an object to be fixed, and the flat wire array fixing device includes:

[0053] A fixing base 1 is used to connect and fix to the object to be fixed. The fixing base is provided with a flat wire row fixing groove 11, and limiting structures 12 are symmetrically provided on two opposite side walls of the flat wire row fixing groove;

[0054] The plug-in fastener 2 is detachably connected to the fixed base to fix the flat wire array in the flat wire array fixing groove. The plug-in fastener includes at least a main body 21 and two limiting arms 22 extending from the main body. The two limiting arms are symmetrically arranged on both sides of the flat wire array to be inserted into the limiting structure for buckling connection. The limiting structure includes an outwardly protruding receiving groove 121, and a self-resetting elastic limiting strip 122 is provided at the bottom of the receiving groove, and a limiting protrusion 123 is provided on the elastic limiting strip. A plurality of limiting steps 221 are provided on the outer side of the limiting arm, and the limiting steps are limited by the limiting structure, specifically, the limiting steps 221 cooperate with the limiting protrusion 123 for limiting. The limiting steps are multiple and arranged vertically. When in use, pinch the main body 21 and insert the two limiting arms 22 into the accommodating groove 121. After entering a certain distance, the limiting step 221 contacts the limiting protrusion 123 and squeezes the limiting protrusion outward, causing the elastic limiting strip to expand outward, leaving space for the limiting step to pass through. When the limiting step 221 passes the limiting protrusion 123, the elastic limiting strip is reset and the limiting protrusion 123 returns to its original position, thereby just blocking the limiting step 221 from withdrawing backward, thereby realizing the buckle connection limit.

[0055] The arrangement of multiple limit steps can avoid frequently replacing the flat wire bus fixture when facing various specifications and models of flat wire bus, or developing various models of flat wire bus fixtures. The same flat wire bus fixture can fix various specifications and has high applicability.

[0056] At the same time, the vertical arrangement design of the limiting steps enables the limiting steps to gradually cooperate with the limiting protrusions during the insertion and fixation of the flat cable row to achieve gradual limiting, thereby enhancing the stability and reliability of the fixation. In addition, this design also makes it easier for users to operate the plug-in parts when installing and removing the flat cable row, thereby improving the convenience of use. In summary, the arrangement design of multiple limiting steps in Example 3 not only improves the applicability of the flat cable row fixing device, but also enhances its stability and convenience, so that the device has better performance and user experience in actual applications.

[0057] The fixing base 1 is fixedly connected to the object to be fixed, and the connection method may include various ways, for example, fixedly connected to the object to be fixed by fasteners, and the fasteners may be bolts, screws, rivets and other structures; for example, fixedly connected to the object to be fixed by adhesives; for example, fixedly connected to the object to be fixed by welding, etc.

[0058] In practical applications, the end of the receiving groove is an opening 124. The opening allows the front end of the limit arm to pass through the bottom of the receiving groove, which is suitable for fixing narrow flat wire strips. Because the need to fix narrow flat wire strips requires the limit step on the limit arm to be positioned very far back, resulting in extra space at the front end of the limit arm.

[0059] In actual application, a buffer 222 is provided on the inner side of the limiting arm. The provision of the buffer 222 can reduce the contact area between the limiting arm 22 and the flat wire row, and reduce the friction and wear caused by direct hard contact. When the limiting arm 22 is inserted into the accommodating groove 121 and contacts the flat wire row, the exit is larger than the flat wire row, which facilitates the flat wire row to enter the interior of the limiting arm. After that, the buffer 222 can effectively disperse the pressure and protect the flat wire row from damage. At the same time, the material of the buffer 222 is preferably an elastic material, such as rubber or silicone, which can not only provide a good buffering effect, but also ensure a close fit between the limiting arm and the flat wire row, thereby improving the stability and reliability of the connection.

[0060] In practice, the inner wall of the flat cable pack's fixing groove is provided with ridges 111. Ribs 111 are designed to reduce friction between the flat cable pack and the inner wall of the fixing groove, acting as a guide to smoothly guide the flat cable pack into the fixing groove, making the installation process more convenient and efficient. When the flat cable pack is placed in the fixing groove, ridges 111 can fit tightly against the surface of the flat cable pack, effectively preventing the flat cable pack from sliding or shifting within the fixing groove, thereby enhancing the stability of the flat cable pack within the fixing groove.

[0061] In actual applications, the fixed base is provided with an adapter (not shown in the figure), and the fixed base is connected and fixed to the object to be fixed through the adapter, and the object to be fixed is provided with a matching connecting socket, etc. The provision of the adapter increases the flexibility of the installation of the fixed base, so that the fixed base can adapt to more types of objects to be fixed. The design of the connecting socket ensures the stability of the connection between the fixed base and the object to be fixed, and avoids loosening or falling off during use. Such a structural design not only improves the applicability and stability of the entire wire row fixing device, but also lays a solid foundation for its wide promotion in practical applications.

The adapter can be a connector such as a bolt, a nut, a buckle, etc. According to the different shapes and structures of the object to be fixed, a suitable adapter is selected for connection. For example, when the object to be fixed is a metal plate with threaded holes, bolts and nuts can be used to secure the fixing base to the metal plate. When the object to be fixed is a smooth surface, connectors such as snaps can be used to securely connect the fixing base to the object to be fixed. The use of adapters greatly enhances the applicability and installation convenience of the flat cable bar fixing device.

[0062] One usage of this embodiment is as follows:

[0063] First, fix the fixed base on the object to be fixed, such as on the car sheet metal, and then place the flat wire row flat into the flat wire row fixing groove, then grasp the main body of the fastener, and insert the two limiting arms of the fastener into the accommodating groove. After entering a certain distance, the limiting step contacts the limiting protrusion and squeezes the limiting protrusion outward, causing the elastic limiting strip to expand outward, leaving space for the limiting step to pass through. When the limiting step passes the limiting protrusion, the elastic limiting strip is reset and the limiting protrusion returns to its original position, thereby just blocking the limiting step from withdrawing backward, that is, preventing the limiting arm from withdrawing from the limiting structure, thereby realizing the snap-fit connection and fixation of the fastener and the fixed base, so as to limit and fix the flat wire row in the flat wire row fixing groove of the fixed base.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
