Most of the new energy vehicles currently on sale in the Chinese market are pure electric vehicles and hybrid vehicles.

[0003] With the shortage of global oil resources and the need for environmental protection, pure electric vehicles and hybrid vehicles have become an important trend in the development of modern vehicles. Among them, the power battery pack, as the power source of pure electric vehicles and hybrid vehicles, is the key point in the research and development of pure electric vehicles and hybrid vehicles. Copper bars and other cables are indispensable parts inside the power battery pack. Due to the long use length of the copper bars, the copper bars need to be fixed on the base. The copper bar is a flat wire row. However, the fixing devices for fixing flat wire rows on the market are very scarce, and the traditional zip tie type nails are no longer applicable to this kind of flat wire row. The reason is that the flat wire row itself is relatively wide and thin. After being tied with the traditional zip tie type nails, it cannot be fixed firmly. Therefore, it is necessary to design a fixing part that is convenient for fixing flat wire rows, can fix flat wire rows well, has good general performance to adapt to various installation and fixing positions, can flexibly install and disassemble flat wire rows, and improve the installation efficiency.

[0021] Advantages of the implementation of the present invention: The universal flat wire row fixing device of the present invention is an efficient, stable and easy-to-operate flat wire row fixing method.

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 creative work are within the scope of protection of the present invention.

[0030] Embodiment 1

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a universal flat wire row fixing device is used to fix a flat wire row on an object to be fixed, and the universal flat wire row fixing device includes:

[0032] A fixing base 1, used for connecting and fixing with an object to be fixed, the fixing base is provided with a flat wire row fixing groove 11 and a transfer interface 13, and limiting structures 12 are symmetrically provided on two opposite side walls of the flat wire row fixing groove;

[0033] The adapter 4 is used to connect and fix with the object to be fixed and / or connect with other wiring harness fixing parts. The adapter is provided with an adapter block 41, and the adapter block 41 is detachably connected with the adapter port 13;

[0034] The plug-in buckle 2 is detachably connected to the fixing base to fix the flat wire row in the fixing groove of the flat wire row. The plug-in buckle at least includes a body 21 and two limit arms 22 extending from the body. The two limit arms are symmetrically arranged on both sides of the flat wire row to be inserted into the limit structure for buckling connection. The adapter 4 includes a first adapter structure 42 and an adapter 43 for connecting and fixing with the object to be fixed.

[0035] The adapter interface 13 includes an adapter groove 131 fixedly connected to the fixed base, guide grooves 132 are respectively provided on both sides of the adapter groove, an adapter limit block 133 is provided above the adapter groove away from the fixed base, and a limit platform 134 is provided on the direction of the adapter limit block toward the fixed base. The adapter block 41 includes a connecting portion 411 fixedly connected to the bottom of the adapter, two extended edges 412 are relatively arranged on both sides of the bottom of the connecting portion, the extended edges are arranged to be inserted into the guide groove, and a bayonet 413 is provided between the two extended edges, and the bayonet cooperates with the limit platform for limiting.

[0036] In this embodiment, the first adapter structure is used to connect and fix the cable tie. In other embodiments, the first adapter structure can be designed as a structure adapted to connect other types of wire harness fixing parts.

[0037] The design of the adapter 4 makes the fixing device have higher flexibility and applicability. Through the detachable connection between the adapter block 41 and the adapter port 13, the connection or disconnection between the adapter and the fixing base can be conveniently realized, and at the same time, it is also convenient to connect with other wire harness fixing parts. The design of the first adapter structure 42 provides a variety of connection method options, enabling the fixing device to adapt to different occasions and requirements.

[0038] The design of the fastener 2 is an important innovation point of the present invention. Through the detachable connection between the fastener and the fixing base, the flat cable can be conveniently fixed in the flat cable fixing groove. At the same time, the setting of the two limiting arms 22 can further increase the stability of the flat cable in the fixing groove. The design of the fastener also takes into account the requirements of easy operation and disassembly, enabling users to easily perform installation and disassembly operations during use.

[0039] The design of the adapter 43 enables the adapter 4 to be firmly connected and fixed to the object to be fixed, thus ensuring the stability and reliability of the entire fixing device. The settings of structures such as the adapter groove 131, the guide groove 132, and the adapter limiting block 133 further increase the stability and applicability of the adapter port 13, enabling the adapter block 41 to be smoothly inserted and fixed in the adapter port, or replacing the adapter 4.

[0040] In practical applications, the adapter limiting block 133 is an elastic and resetable structure, which is convenient for the bayonet of the adapter block to be inserted into the adapter groove.

[0041] Among them, the limiting structure includes a receiving groove 121 protruding outward, and an elastic limiting strip 122 that can self-reset is provided at the bottom of the receiving groove. 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. The limiting step is limited by the limiting structure. Specifically, the limiting step 221 cooperates with the limiting protrusion 123 for limiting. During use, hold 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 to leave a passing space for the limiting step. When the limiting step 221 passes through the limiting protrusion 123, the elastic limiting strip resets, and the limiting protrusion 123 returns to its original position, thus exactly blocking the backward withdrawal of the limiting step 221, thereby realizing the snap connection and limiting.

[0042] 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 a narrow flat wire row. Because the narrow flat wire row needs to be fixed, the limit step on the limit arm needs to be located very far back, resulting in an extra position at the front end of the limit arm.

[0043] In practical applications, a buffer 222 is provided on the inner side of the limit arm. The provision of the buffer 222 can reduce the contact area between the limit arm 22 and the flat wire row, and reduce the friction and wear caused by direct hard contact. When the limit arm 22 is inserted into the receiving 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 inside of the limit 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 the close fit between the limit arm and the flat wire row, thereby improving the stability and reliability of the connection.

[0044] In practical applications, a ridge 111 is provided on the inner wall of the flat cable row fixing groove. The ridge 111 is provided to reduce the friction between the flat cable row and the inner wall of the fixing groove, and can play a guiding role, guiding the flat cable row to smoothly enter the fixing groove, making the installation process more convenient and efficient. When the flat cable row is placed in the fixing groove, the ridge 111 can fit tightly on the surface of the flat cable row, effectively preventing the flat cable row from sliding or displacing in the fixing groove, thereby enhancing the stability of the flat cable row in the fixing groove.

[0045] In actual applications, an adapter (not shown in the figure) is provided on the fixed base, 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, 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.

[0046] One usage of this embodiment is as follows:

[0047] First, fix the fixed base on the object to be fixed, for example, on the automotive sheet metal. Then, lay the flat wire in a flat manner into the flat wire fixing groove of the fixed base. Next, grasp the main body of the fastener and insert the two limiting arms of the fastener into the receiving groove. After entering a certain distance, the limiting step contacts the limiting protrusion and presses the limiting protrusion outward, causing the elastic limiting strip to expand outward, leaving a passage space for the limiting step. When the limiting step passes through the limiting protrusion, the elastic limiting strip resets, and the limiting protrusion returns to its original position, thus exactly blocking the limiting step from retreating backward, that is, preventing the limiting arm from exiting the limiting structure, thereby realizing the snap connection and fixation between the fastener and the fixed base to limit and fix the flat wire in the flat wire fixing groove of the fixed base. Then, after inserting the adapter block of the adapter into the adapter port for limiting and fixing, through the first adapter structure on the adapter, other wire harness fixing parts such as cable ties can be connected, and other types of wire harnesses can be fixed. At the same time, through the adapter head, it can be quickly installed and fixed on the object to be fixed, such as the automotive sheet metal.

[0048] Embodiment 2

[0049] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, a universal flat wire fixing device for fixing a flat wire on an object to be fixed, the universal flat wire fixing device comprising:

[0050] A fixed base 1 for connecting and fixing with the object to be fixed, the fixed base is provided with a flat wire fixing groove 11 and an adapter port 13, and limiting structures 12 are symmetrically arranged on two opposite side walls of the flat wire fixing groove;

[0051] An adapter 4 for connecting and fixing with the object to be fixed and / or connecting with other wire harness fixing parts, the adapter is provided with an adapter block 41, and the adapter block 41 is detachably connected to the adapter port 13;

[0052] A fastener 2 detachably connected to the fixed base to fix the flat wire in the flat wire fixing groove, the fastener at least includes 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 to be inserted into the limiting structure for snap connection, and the fastener main body 21 is connected to the fixed base 1 through a flexible connecting member 3.

[0053] In practical applications, the length of the flexible connecting member at least satisfies that when the limiting arm just disengages from the flat wire fixing groove, the flexible connecting member is still in a relaxed state or just in a taut state. The flexible connecting member is a rope body connecting the fastener and the fixed base. In practical applications, the flexible connecting member is an integral conditional object integrally formed with the fastener and the fixed base.

[0054] The adapter 4 includes a first adapter structure 42 and an adapter head 43 for connecting and fixing to an object to be fixed.

[0055] The adapter port 13 includes an adapter slot 131 fixedly connected to the fixed base. Guide slots 132 are respectively provided on both sides of the adapter slot. An adapter limit block 133 is provided above the adapter slot facing away from the fixed base. A limit platform 134 is provided on the side of the adapter limit block facing the fixed base. The adapter block 41 includes a connecting portion 411 fixedly connected to the bottom of the adapter. Two edge extensions 412 are oppositely arranged on both sides of the bottom of the connecting portion. The edge extensions are arranged to be insertable into the guide slots. A bayonet 413 is provided between the two edge extensions. The bayonet cooperates with the limit platform for limiting.

[0056] In this embodiment, the first adapter structure is used to connect and fix a cable tie. In other embodiments, the first adapter structure can be designed as a structure adapted to connect other types of wire harness fixing parts.

[0057] The design of the adapter 4 makes the fixing device have higher flexibility and applicability. Through the detachable connection between the adapter block 41 and the adapter port 13, the connection or disconnection between the adapter and the fixed base can be conveniently realized, and at the same time, it is also convenient to connect with other wire harness fixing parts. The design of the first adapter structure 42 provides a variety of connection method options, enabling the fixing device to adapt to different occasions and requirements.

[0058] The design of the snap-fastener 2 is an important innovation point of the present invention. Through the detachable connection between the snap-fastener and the fixed base, the flat cable row can be conveniently fixed in the flat cable row fixing slot, and at the same time, the setting of the two limit arms 22 can further increase the stability of the flat cable row in the fixing slot. The design of the snap-fastener also takes into account the requirements of easy operation and disassembly, enabling users to easily perform installation and disassembly operations during use.

[0059] The design of the adapter head 43 enables the adapter 4 to be firmly connected and fixed to the object to be fixed, thus ensuring the stability and reliability of the entire fixing device. The settings of structures such as the adapter slot 131, the guide slots 132, and the adapter limit block 133 further increase the stability and applicability of the adapter port 13, enabling the adapter block 41 to be smoothly inserted and fixed in the adapter port, or replacing the adapter 4.

[0060] In practical applications, the transfer limit block 133 is an elastic and resetable structure, which facilitates the insertion of the bayonet of the transfer block into the transfer slot. Among them, the limit structure includes a receiving groove 121 protruding outward, and an elastic limit strip 122 that can self-reset is provided at the bottom of the receiving groove. A limit protrusion 123 is provided on the elastic limit strip. A limit step 221 is provided on the outer side of the limit arm. The limit step is limited by the limit structure. Specifically, the limit step 221 cooperates with the limit protrusion 123 for limitation. During use, hold the body 21 and insert the two limit arms 22 into the receiving groove 121. After entering a certain distance, the limit step 221 contacts the limit protrusion 123 and extrudes the limit protrusion outward, causing the elastic limit strip to expand outward and leaving a passing space for the limit step. When the limit step 221 passes through the limit protrusion 123, the elastic limit strip resets, and the limit protrusion 123 returns to its original position, thus exactly blocking the limit step 221 from withdrawing backward, thereby realizing snap connection and limitation.

[0061] In practical applications, the end of the receiving groove is an opening 124. The setting of the opening enables the front end of the limit arm to pass through the bottom of the receiving groove, which is suitable for fixing a flat wire row with a narrow width. Because a narrow flat wire row needs to be fixed, the position of the limit step on the limit arm is extremely far back, resulting in an extra position at the front end of the limit arm.

[0062] In practical applications, a buffer member 222 is provided on the inner side of the limit arm. The setting of this buffer member 222 can reduce the contact area between the limit arm 22 and the flat wire row, and reduce the friction and wear caused by direct hard contact. When the limit arm 22 is inserted into the receiving groove 121 and contacts the flat wire row, the outlet is larger than the flat wire row, which is convenient for the flat wire row to enter the inside of the limit arm. Then, the buffer member 222 can effectively disperse the pressure and protect the flat wire row from damage. At the same time, the material of the buffer member 222 is preferably an elastic material such as rubber or silica gel, which can not only provide a good buffering effect, but also ensure a tight fit between the limit arm and the flat wire row, improving the stability and reliability of the connection.

[0063] In practical applications, convex ribs 111 are provided on the inner wall of the flat wire row fixing groove. The setting of the convex ribs 111 is aimed at reducing the friction between the flat wire row and the inner wall of the fixing groove, and can play a guiding role to guide the flat wire row to smoothly enter the fixing groove, making the installation process more convenient and efficient. When the flat wire row is placed in the fixing groove, the convex ribs 111 can closely fit on the surface of the flat wire row, effectively preventing the flat wire row from sliding or displacing in the fixing groove, thereby enhancing the stability of the flat wire row in the fixing groove.

[0064] In practical applications, an adapter (not shown in the figure) is provided on the fixed base, 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 and the like. 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 line 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 fix the fixing base on the metal plate; when the object to be fixed is a smooth surface, a connector such as a buckle can be used to firmly connect the fixing base to the object to be fixed. The use of the adapter greatly enhances the applicability and installation convenience of the universal flat cable row fixing device.

[0065] One usage of this embodiment is as follows:

[0066] First, fix the fixing base on the object to be fixed, such as a car sheet metal, and then place the flat wire row flat into the flat wire row fixing groove, then grab the main body of the plug buckle, insert the two limiting arms of the plug buckle into the accommodating groove, and after entering a certain distance, the limiting step contacts the limiting protrusion and squeezes the limiting protrusion outward, so that the elastic limiting strip expands outward, leaving space for the limiting step to pass through, and 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 buckling connection and fixation of the plug buckle and the fixing base, so as to limit and fix the flat wire row in the flat wire row fixing groove of the fixing base; then insert the adapter block of the adapter into the adapter interface for limit fixation, and other wiring harness fixing parts such as cable ties can be connected through the first adapter structure on the adapter, and other types of wiring harnesses can be fixed. At the same time, through the adapter, it can be quickly installed and fixed on the object to be fixed, such as a car sheet metal.

[0067] Embodiment 3

[0068] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a universal flat wire row fixing device is used to fix a flat wire row on an object to be fixed, and the universal flat wire row fixing device includes:

[0069] A fixed base 1 for connecting and fixing to an object to be fixed. A flat cable fixing groove 11 and an adapter 13 are provided on the fixed base. Limiting structures 12 are symmetrically arranged on two opposite side walls of the flat cable fixing groove.

[0070] An adapter 4 for connecting and fixing to an object to be fixed and / or connecting to other wire harness fixing parts. An adapter block 41 is provided on the adapter. The adapter block 41 is detachably connected to the adapter 13.

[0071] A fastening part 2 is detachably connected to the fixed base to fix a flat cable in the flat cable fixing groove. The fastening part at least includes a body 21 and two limiting arms 22 extending from the body. The two limiting arms are symmetrically arranged on both sides of the flat cable to be inserted into the limiting structure for snap connection. The limiting structure includes a receiving groove 121 protruding outward. An elastically self - resetting limiting strip 122 is provided at the bottom of the receiving groove. A limiting protrusion 123 is provided on the elastically limiting strip. A plurality of limiting steps 221 are provided on the outer side of the limiting arm. The limiting steps are limited by the limiting structure. Specifically, the limiting step 221 cooperates with the limiting protrusion 123 for limiting. The limiting steps are arranged vertically. During use, hold 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 externally presses the limiting protrusion, causing the elastically limiting strip to expand outward, leaving a passing space for the limiting step. When the limiting step 221 passes through the limiting protrusion 123, the elastically limiting strip resets, and the limiting protrusion 123 returns to its original position, thus exactly blocking the limiting step 221 from retreating backward, thereby realizing snap - connection limiting.

[0072] The arrangement of multiple limiting steps can, when facing flat cables of various specifications and models, avoid frequently replacing the universal flat cable fixing device or developing multiple models of universal flat cable fixing devices. The same universal flat cable fixing device can fix various specifications, with high applicability.

[0073] 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 fixing process of the flat cable, realizing gradual limiting, enhancing the stability and reliability of the fixation. In addition, this design also facilitates the user to more easily operate the fastening part when installing and disassembling the flat cable, improving the convenience of use. In summary, the arrangement design of multiple limiting steps in Embodiment 3 not only improves the applicability of the universal flat cable fixing device, but also enhances its stability and convenience, making the device have better performance and user experience in practical applications.

[0074] The adapter 4 includes a first adapter structure 42 and an adapter head 43 for connecting and fixing to an object to be fixed.

[0075] The adapter 13 includes an adapter slot 131 fixedly connected to the fixed base. Guide slots 132 are respectively provided on both sides of the adapter slot. An adapter limit block 133 is provided above the adapter slot facing away from the fixed base. A limit platform 134 is provided on the adapter limit block facing the direction of the fixed base. The adapter block 41 includes a connecting portion 411 fixedly connected to the bottom of the adapter. Two edge extensions 412 are oppositely arranged on both sides of the bottom of the connecting portion. The edge extensions are arranged to be insertable into the guide slots. A bayonet 413 is provided between the two edge extensions. The bayonet cooperates with the limit platform for limiting.

[0076] In this embodiment, the first adapter structure is used to connect and fix the cable tie. In other embodiments, the first adapter structure can be designed as a structure adapted to connect other types of wire harness fixing parts.

[0077] The design of the adapter 4 makes the fixing device have higher flexibility and applicability. Through the detachable connection between the adapter block 41 and the adapter 13, the connection or disconnection between the adapter and the fixed base can be conveniently realized, and at the same time, it is also convenient to connect with other wire harness fixing parts. The design of the first adapter structure 42 provides a variety of connection method options, enabling the fixing device to adapt to different occasions and requirements.

[0078] The design of the buckle 2 is an important innovation point of the present invention. Through the detachable connection between the buckle and the fixed base, the flat cable can be conveniently fixed in the flat cable fixing slot. At the same time, the setting of the two limit arms 22 can further increase the stability of the flat cable in the fixing slot. The design of the buckle also takes into account the requirements of easy operation and disassembly, enabling users to easily perform installation and disassembly operations during use.

[0079] The design of the adapter 43 enables the adapter 4 to be firmly connected and fixed to the object to be fixed, thereby ensuring the stability and reliability of the entire fixing device. The settings of structures such as the adapter slot 131, the guide slot 132, and the adapter limit block 133 further increase the stability and applicability of the adapter 13, enabling the adapter block 41 to be smoothly inserted and fixed in the adapter, or replacing the adapter 4.

[0080] In practical applications, the adapter limit block 133 is an elastic and resetable structure, which is convenient for the bayonet of the adapter block to be inserted into the adapter slot. In practical applications, the end of the receiving slot is an opening 124. The setting of the opening enables the front end of the limit arm to pass through the bottom of the receiving slot, which is suitable for fixing a flat cable with a relatively narrow width. Because a narrow flat cable needs to be fixed, the position of the limit step on the limit arm is extremely backward, resulting in an extra position at the front end of the limit arm.

[0081] In practical applications, a buffer 222 is provided on the inner side of the limit arm. The provision of the buffer 222 can reduce the contact area between the limit arm 22 and the flat wire row, and reduce the friction and wear caused by direct hard contact. When the limit arm 22 is inserted into the receiving 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 inside of the limit 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 the close fit between the limit arm and the flat wire row, thereby improving the stability and reliability of the connection.

[0082] In practical applications, a ridge 111 is provided on the inner wall of the flat cable row fixing groove. The ridge 111 is provided to reduce the friction between the flat cable row and the inner wall of the fixing groove, and can play a guiding role, guiding the flat cable row to smoothly enter the fixing groove, making the installation process more convenient and efficient. When the flat cable row is placed in the fixing groove, the ridge 111 can fit tightly on the surface of the flat cable row, effectively preventing the flat cable row from sliding or displacing in the fixing groove, thereby enhancing the stability of the flat cable row in the fixing groove.

[0083] In practical applications, an adapter (not shown in the figure) is provided on the fixed base, 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 and the like. 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 line 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 fix the fixing base on the metal plate; when the object to be fixed is a smooth surface, a connector such as a buckle can be used to firmly connect the fixing base to the object to be fixed. The use of the adapter greatly enhances the applicability and installation convenience of the universal flat cable row fixing device.

[0084] One usage of this embodiment is as follows:

[0085] First, fix the fixed base on the object to be fixed, such as on the automotive sheet metal. Then, lay the flat wire in a flat manner into the flat wire row fixing groove. Next, grasp the main body of the fastener and insert the two limiting arms of the fastener into the receiving groove. After entering a certain distance, the limiting step contacts the limiting protrusion and presses the limiting protrusion outwards, causing the elastic limiting strip to expand outwards and leaving a passing space for the limiting step. When the limiting step passes the limiting protrusion, the elastic limiting strip resets and the limiting protrusion returns to its original position, thus exactly blocking the limiting step from withdrawing backwards, that is, preventing the limiting arm from withdrawing from the limiting structure, thereby realizing the snap connection and fixation of the fastener and the fixed base to limit and fix the flat wire row in the flat wire row fixing groove of the fixed base. Then, after inserting the adapter block of the adapter into the adapter port for limiting and fixing, through the first adapter structure on the adapter, other wire harness fixing parts such as cable ties can be connected, and other types of wire harnesses can be fixed. At the same time, through the adapter head, it can be quickly installed and fixed on the object to be fixed, such as automotive sheet metal.

[0086] As described above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
