Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] Embodiment one

[0031] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a universal flat wire harness fixing device for fixing a flat wire harness on a to-be-fixed object, the universal flat wire harness fixing device comprises:

[0032] A fixing base 1 for connecting and fixing with the to-be-fixed object, the fixing base is provided with a flat wire harness fixing groove 11 and an adapter port 13, and a limiting structure 12 is symmetrically arranged on the opposite side walls of the flat wire harness fixing groove;

[0033] An adapter 4 for connecting and fixing with the to-be-fixed object and / or connecting with other wire harness fixing members, the adapter is provided with an adapter block 41, and the adapter block 41 is detachably connected with the adapter port 13;

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

[0035] The adapter port 13 comprises an adapter groove 131 fixedly connected with the fixing base, the two sides of the adapter groove are respectively provided with a guide groove 132, an adapter limiting block 133 is arranged above the adapter groove away from the fixing base, a limiting table 134 is arranged on the adapter limiting block in the direction towards the fixing base, the adapter block 41 comprises a connecting part 411 fixedly connected with the bottom of the adapter, two extension edges 412 are oppositely arranged on the bottom of the connecting part, the extension edges are arranged to be inserted into the guide grooves, a clamping opening 413 is arranged between the two extension edges, and the clamping opening is matched with the limiting table to limit.

[0036] In the embodiment, the first adapter structure is used to connect the fixing cable tie, and in other embodiments, the first adapter structure can be designed to adapt to other types of wiring harness fixing structures.

[0037] The design of the adapter 4 makes the fixing device more flexible and applicable. Through the detachable connection of the adapter block 41 and the adapter port 13, the connection or disconnection of the adapter and the fixing base can be easily realized, and the connection with other wiring harness fixing structures is also facilitated. The design of the first adapter structure 42 provides a variety of connection methods for selection, so that the fixing device can adapt to different occasions and needs.

[0038] The design of the plug-in buckle 2 is an important innovation of the present application. Through the detachable connection of the plug-in buckle and the fixing base, the flat wire harness can be easily fixed in the flat wire harness fixing groove, and the setting of the two limiting arms 22 can further increase the stability of the flat wire harness in the fixing groove. The design of the plug-in buckle also takes into account the need for easy operation and disassembly, so that the user can easily install and disassemble during use.

[0039] The design of the adapter 4 makes the adapter 4 firmly connected and fixed with the object to be fixed, thereby ensuring the stability and reliability of the entire fixing device. The setting of the adapter slot 131, the guide slot 132 and the adapter limiting block 133 further increases the stability and applicability of the adapter port 13, so that the adapter block 41 can be smoothly inserted and fixed in the adapter port, or the adapter 4 can be replaced.

[0040] In actual application, the adapter limiting block 133 is a resilient resettable structure, which facilitates the bayonet insertion of the adapter block into the adapter slot.

[0041] The limiting structure includes an outwardly protruding receiving slot 121, the bottom of which is provided with a self-resetting elastic limiting strip 122, and the elastic limiting strip is provided with a limiting protrusion 123. The outer side of the limiting arm is provided with a limiting step 221, and the limiting step is limited by the limiting structure, specifically the limiting step 221 and the limiting protrusion 123 cooperate to limit. In use, pinch the body 21, insert the two limiting arms 22 into the receiving slot 121, after entering a distance, the limiting step 221 contacts the limiting protrusion 123, and extrudes the limiting protrusion outward, so that the elastic limiting strip expands outward, leaving 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, thereby blocking the limiting step 221 from exiting backward, thereby realizing the buckling connection limiting.

[0042] In practical applications, the accommodating groove end is an opening 124. The opening is arranged so that the front end of the limiting arm can pass through the bottom of the accommodating groove, and 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 limiting step on the limiting arm needs to be extremely rear, thereby causing the front end of the limiting arm to have an extra position.

[0043] In practical applications, the inner side of the limiting arm is provided with a buffer 222. The arrangement 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 outlet is larger than the flat wire row, which facilitates the flat wire row to enter the inside of the limiting arm. Then, the buffer 222 can effectively disperse the pressure and protect the flat wire row from being damaged. 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 good buffering effect, but also ensure the close fit between the limiting arm and the flat wire row, improve the stability and reliability of the connection.

[0044] In practical applications, the inner wall of the flat wire row fixing groove is provided with a convex rib 111. The arrangement of the convex rib 111 aims to reduce the friction between the flat wire row and the inner wall of the fixing groove, and can guide the flat wire row to smoothly enter the fixing groove, so that the installation process is more convenient and efficient. When the flat wire row is placed in the fixing groove, the convex rib 111 can closely fit on the surface of the flat wire row, effectively preventing the flat wire row from sliding or moving in the fixing groove, thereby enhancing the stability of the flat wire row in the fixing groove.

[0045] In practical applications, the fixing base is provided with an adapter (not shown in the figure), and the fixing base is connected and fixed to the to-be-fixed object through the adapter. The to-be-fixed object is provided with a matching connecting card seat and the like. The arrangement of the adapter increases the flexibility of the installation of the fixing base, so that the fixing base can adapt to more types of to-be-fixed objects. The design of the connecting card seat ensures the stability of the connection between the fixing base and the to-be-fixed object, and avoids the loosening or falling off during use. Such a structure design not only improves the applicability and stability of the entire wire row fixing device, but also lays a solid foundation for its widespread application in practical applications.

[0046] One use of the embodiment is as follows:

[0047] First, the fixed base is fixed on the object to be fixed, such as the automobile sheet metal, then the flat wire row is placed in the flat wire row fixing groove, then the main body of the plug-in buckle is grabbed, and the two limiting arms of the plug-in buckle are inserted into the accommodating groove, after a distance, the limiting step contacts the limiting protrusion, and the limiting protrusion is extruded outward, so that the elastic limiting strip expands outward, leaving a passing 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 the original position, thereby exactly 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-in buckle and the fixed base, so as to fix the flat wire row in the flat wire row fixing groove of the fixed base; then the adapter block of the adapter is inserted into the adapter port for limiting fixation, and through the first adapter structure on the adapter, other wire harness fixing members such as a cable tie can be connected, and other types of wire harnesses can be fixed, and through the adapter, the quick installation and fixation on the object to be fixed, such as the automobile sheet metal, can be realized.

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

The flexible connecting piece is a rope body connecting the plug-in buckle and the fixed base. In actual application, the flexible connecting piece is an integral condition object integrally formed with the plug-in buckle and the fixed base.

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

[0055] The adapter interface 13 comprises an adapter slot 131 fixedly connected to the fixing base, two guide slots 132 are respectively arranged on the two sides of the adapter slot, an adapter limiting block 133 is arranged above the adapter slot away from the fixing base, a limiting table 134 is arranged on the adapter limiting block towards the fixing base, the adapter block 41 comprises a connecting part 411 fixedly connected to the bottom of the adapter block, two extension edges 412 are respectively arranged on the two sides of the bottom of the connecting part, the extension edges are arranged to be insertable into the guide slots, and a bayonet 413 is arranged between the two extension edges, the bayonet cooperates with the limiting table to limit.

[0056] In the embodiment, the first adapter structure is used to connect and fix the cable tie, and in other embodiments, the first adapter structure can be designed to adapt to other types of wiring harness fixing structures.

[0057] The design of the adapter 4 makes the fixing device more flexible and applicable. Through the detachable connection of the adapter block 41 and the adapter interface 13, the connection or disconnection of the adapter and the fixing base can be easily realized, and the connection with other wiring harness fixing devices is also facilitated. The design of the first adapter structure 42 provides a variety of connection methods for selection, so that the fixing device can adapt to different occasions and needs.

[0058] The design of the plug-in buckle 2 is an important innovation point of the present application. Through the detachable connection of the plug-in buckle and the fixing base, the flat wire array can be fixed in the flat wire array fixing slot, and the two limiting arms 22 can further increase the stability of the flat wire array in the fixing slot. The design of the plug-in buckle also takes into account the needs of easy operation and disassembly, so that the user can easily install and disassemble during use.

[0059] The design of the adapter head 43 makes the adapter 4 firmly connected and fixed with the object to be fixed, thereby ensuring the stability and reliability of the entire fixing device. The arrangement of the adapter slot 131, the guide slot 132 and the adapter limiting block 133 further increases the stability and applicability of the adapter interface 13, so that the adapter block 41 can be smoothly inserted and fixed in the adapter interface, or the adapter 4 can be replaced.

[0060] In practical application, the adapter limiting block 133 is an elastic resettable structure, facilitating the insertion of the adapter block into the adapter slot. The limiting structure includes an accommodating groove 121 provided outwardly, and the bottom of the accommodating groove is provided with an elastic limiting strip 122 which can reset, and the elastic limiting strip is provided with a limiting protrusion 123. The outer side of the limiting arm is provided with a limiting step 221, and the limiting step is limited by the limiting structure, specifically, the limiting step 221 is limited by the limiting protrusion 123. In use, pinch the body 21, and insert the two limiting arms 22 into the accommodating groove 121, after entering a distance, the limiting step 221 contacts the limiting protrusion 123, and extrudes the limiting protrusion outward, so that the elastic limiting strip expands outward, leaving 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 the original position, thereby exactly blocking the limiting step 221 from exiting backward, thereby realizing the buckling connection limiting.

[0061] In practical application, the end of the accommodating groove is an opening 124. The opening is provided, so that the front end of the limiting arm can pass through the bottom of the accommodating groove, and is suitable for fixing a flat wire row with a relatively narrow width. Because a narrow flat wire row needs to be fixed, the position of the limiting step on the limiting arm needs to be extremely rear, thereby causing the front end of the limiting arm to have an extra position.

[0062] In practical application, the inner side of the limiting arm is provided with a buffer 222. 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 outlet is larger than the flat wire row, facilitating the flat wire row to enter the inside of the limiting arm, and then the buffer 222 can effectively disperse the pressure, protecting the flat wire row from being damaged. 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 good buffering effect, but also ensure the close fit between the limiting arm and the flat wire row, improve the stability and reliability of the connection.

[0063] In practical application, the inner wall of the flat wire row fixing groove is provided with a convex rib 111. The provision of the convex rib 111 aims to reduce the friction between the flat wire row and the inner wall of the fixing groove, and can 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 rib 111 can be closely fitted 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, the fixing base is provided with an adapter (not shown in the figure), and the fixing base is connected and fixed to the to-be-fixed object through the adapter. The to-be-fixed object is provided with a matching connecting clamping seat and the like. The provision of the adapter increases the flexibility of the installation of the fixing base, so that the fixing base can be adapted to more types of to-be-fixed objects. The design of the connecting clamping seat ensures the stability of the connection between the fixing base and the to-be-fixed object, avoiding loosening or falling off during use. Such a structural design not only improves the applicability and stability of the entire flat cable fixing device, but also lays a solid foundation for its widespread application in practical applications. Further, the fixing base can be connected and fixed to the to-be-fixed object through the adapter. The design of the adapter makes the connection mode of the fixing base more flexible and diverse. The adapter can be a bolt, a nut, a buckle or the like. According to the different shapes and structures of the to-be-fixed object, a suitable adapter is selected for connection. For example, when the to-be-fixed object is a metal plate with threaded holes, a bolt and a nut can be used to fix the fixing base to the metal plate; when the to-be-fixed object is a smooth surface, a buckle or the like can be used to firmly connect the fixing base to the to-be-fixed object. The use of the adapter greatly enhances the applicability and installation convenience of the universal flat cable fixing device.

[0065] One use of the embodiment is as follows:

[0066] First, the fixing base is fixed to the to-be-fixed object, for example, to the automobile sheet metal, and then the flat cable is placed flat into the flat cable fixing groove. Then, the main body of the plug-in buckle is gripped, and the two limiting arms of the plug-in buckle are inserted into the accommodating groove. After a certain distance, the limiting step contacts the limiting protrusion and extrudes the limiting protrusion outward, so that the elastic limiting strip expands outward, leaving a passing 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, thereby exactly blocking the limiting step from exiting backward, i.e., preventing the limiting arm from exiting the limiting structure, thereby achieving the buckling connection and fixation of the plug-in buckle and the fixing base to fix the flat cable in the flat cable fixing groove of the fixing base. Then, after the adapter block of the adapter is inserted into the adapter port for limiting and fixing, the first adapter structure on the adapter can be connected to other wire harness fixing members such as a cable tie, and other types of wire harness can be fixed. At the same time, through the adapter, it can be quickly installed and fixed to the to-be-fixed object, such as the automobile sheet metal.

[0067] Embodiment Three

[0068] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a universal flat cable fixing device is used to fix a flat cable to a to-be-fixed object, and the universal flat cable fixing device comprises:

[0069] The fixed base 1 is used for connecting and fixing with the object to be fixed, and the fixed base is provided with a flat wire fixing groove 11 and an adapter port 13. The opposite two side walls of the flat wire fixing groove are symmetrically provided with limiting structures 12.

[0070] The adapter 4 is used 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, which is detachably connected with the adapter port 13.

[0071] The plug-in buckle 2 is detachably connected with the fixed base to fix the flat wire in the flat wire fixing groove. The plug-in buckle 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 wire to be inserted into the limiting structure for buckling connection. The limiting structure includes a concave accommodation groove 121. The bottom of the accommodation groove is provided with a self-resetting elastic limiting strip 122. The elastic limiting strip is provided with a limiting protrusion 123. The outer side of the limiting arm is provided with a plurality of limiting steps 221. The limiting steps are limited with the limiting structure, specifically, the limiting steps 221 are limited with the limiting protrusions 123. The limiting steps are vertically arranged. In use, the body 21 is pinched, and the two limiting arms 22 are inserted into the accommodation groove 121. After a certain distance, the limiting steps 221 contact the limiting protrusions 123, and the limiting protrusions are extruded outward, so that the elastic limiting strip expands outward, leaving a passing space for the limiting steps. When the limiting steps 221 pass through the limiting protrusions 123, the elastic limiting strip resets, and the limiting protrusions 123 return to the original position, thereby blocking the limiting steps 221 from exiting backward, thereby achieving buckling connection and limiting.

[0072] The arrangement of multiple limiting steps can be used for various specifications and models of flat wires without frequent replacement of the universal flat wire fixing device or development of multiple models of the universal flat wire fixing device. The same universal flat wire fixing device can fix multiple specifications, and has high applicability.

[0073] Meanwhile, the vertical arrangement of the limiting steps enables the limiting steps to gradually cooperate with the limiting protrusions during the insertion and fixation of the flat wire, thereby achieving gradual limiting and enhancing the stability and reliability of the fixation. In addition, this design also facilitates the user to operate the plug-in buckle more easily during the installation and disassembly of the flat wire, thereby improving the convenience of use. In summary, the arrangement of multiple limiting steps in embodiment three not only improves the applicability of the universal flat wire fixing device, but also enhances the stability and convenience thereof, so that the device has better performance and user experience in actual application.

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

[0075] The adapter interface 13 includes an adapter slot 131 fixedly connected to the fixed base, both sides of the adapter slot are respectively provided with a guide slot 132, an adapter limiting block 133 is arranged above the adapter slot away from the fixed base, a limiting table 134 is arranged on the adapter limiting block in the direction of the fixed base, the adapter block 41 includes a connecting part 411 fixedly connected with the bottom of the adapter, two extension edges 412 are oppositely arranged at the bottom of the connecting part, the extension edges are arranged to be inserted into the guide slot, and a clamping hole 413 is arranged between the two extension edges and cooperates with the limiting table to limit.

[0076] In the embodiment, the first adapter structure is used for connecting and fixing the cable tie, and in other embodiments, the first adapter structure can be designed to be suitable for connecting and fixing other types of wire harness fixing members.

[0077] The design of the adapter 4 makes the fixing device have higher flexibility and applicability. Through the detachable connection of the adapter block 41 and the adapter interface 13, the connection or disconnection of the adapter and the fixed base can be conveniently realized, and the connection with other wire harness fixing members is also facilitated. The design of the first adapter structure 42 provides a variety of connection modes for selection, so that the fixing device can adapt to different occasions and needs.

[0078] The design of the plug-in buckle 2 is an important innovation point of the present application. Through the detachable connection of the plug-in buckle and the fixed base, the flat wire harness can be conveniently fixed in the flat wire harness fixing slot, and the setting of the two limiting arms 22 can further increase the stability of the flat wire harness in the fixing slot. The design of the plug-in buckle also takes into account the needs of easy operation and disassembly, so that the user can easily install and disassemble during use.

[0079] The design of the adapter 4 makes the adapter 4 firmly connected and fixed with the to-be-fixed object, thereby ensuring the stability and reliability of the entire fixing device. The setting of the adapter slot 131, the guide slot 132 and the adapter limiting block 133 further increases the stability and applicability of the adapter interface 13, so that the adapter block 41 can be smoothly inserted and fixed in the adapter interface, or the adapter 4 can be replaced.

[0080] In actual application, the adapter limiting block 133 is an elastic reset structure, which facilitates the insertion of the clamping hole of the adapter block into the adapter slot. In actual application, the end of the accommodating slot is an opening 124. The setting of the opening makes the front end of the limiting arm pass through the bottom of the accommodating slot, which is suitable for fixing a flat wire harness with a narrow width. Because a narrow flat wire harness needs to be fixed, the position of the limiting step on the limiting arm needs to be extremely rear, thereby causing the front end of the limiting arm to have an extra position.

[0081] In practical applications, a buffer 222 is provided on the inner side of the limiting arm. This buffer 222 reduces the contact area between the limiting arm 22 and the flat cable tray, and reduces friction and wear caused by direct hard contact. When the limiting arm 22 is inserted into the receiving groove 121 and contacts the flat cable tray, the outlet is larger than the flat cable tray, facilitating the entry of the flat cable tray into the limiting arm. The buffer 222 then effectively disperses pressure, protecting the flat cable tray from damage. Furthermore, the buffer 222 is preferably made of an elastic material, such as rubber or silicone, which provides good cushioning while ensuring a tight fit between the limiting arm and the flat cable tray, improving the stability and reliability of the connection.

[0082] In practical applications, the inner wall of the flat cable tray fixing groove is provided with protruding ridges 111. The protruding ridges 111 are designed to reduce the friction between the flat cable tray and the inner wall of the fixing groove, and can act as a guide to guide the flat cable tray smoothly into the fixing groove, making the installation process more convenient and efficient. When the flat cable tray is placed in the fixing groove, the protruding ridges 111 can fit tightly against the surface of the flat cable tray, effectively preventing the flat cable tray from sliding or displacing in the fixing groove, thereby enhancing the stability of the flat cable tray in the fixing groove.

[0083] In practical applications, the fixed base is equipped with an adapter (not shown in the figure). The fixed base is connected and fixed to the object to be fixed via the adapter, and the object to be fixed is equipped with a matching connecting bracket, etc. The adapter increases the installation flexibility of the fixed base, allowing it to adapt to a wider variety of objects. The design of the connecting bracket ensures the stability of the connection between the fixed base and the object to be fixed, preventing loosening or detachment during use. This structural design not only improves the applicability and stability of the entire cable tray fixing device but also lays a solid foundation for its widespread application in practical applications. Furthermore, the fixed base can be connected and fixed to the object to be fixed via 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 bolt, nut, clip, or other connecting component; a suitable adapter is selected for connection based on the different shapes and structures of the object to be fixed. 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, clips or other connectors can be used to firmly connect the fixing base to the object. The use of adapters greatly enhances the applicability and ease of installation of the universal flat cable fixing device.

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

[0085] First, fix the mounting base to the object to be fixed, such as to a car body panel. Then, place the flat cable tray flat into the flat cable tray 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 pushes 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 resets, and the limiting protrusion returns to its original position, thus preventing the limiting step from exiting backward, i.e., preventing the limiting arms from exiting the limiting structure. This achieves the fastening connection and fixation between the fastener and the mounting base, thereby limiting and fixing the flat cable tray in the flat cable tray fixing groove of the mounting base. Then, insert the adapter block of the adapter into the adapter interface for limiting and fixing. Through the first adapter structure on the adapter, other wire harness fixing components such as cable ties can be connected to fix other types of wire harnesses. At the same time, through the adapter, it can be quickly installed and fixed to the object to be fixed, such as a car body panel.

[0086] 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 variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
