[0047] The following describes a cable management structure 10 according to an embodiment of the present invention with reference to the accompanying drawings.

[0048] like Figure 1 As shown, the cable management structure 10 according to the embodiment of the utility model includes a fixing portion 1 and a limiting portion 2 .

[0049] Specifically, Figure 1 and Figure 3As shown, the fixing portion 1 is provided with a plurality of fixing holes 11 for fixing the plug-in terminals 20, and the male ends or female ends of the plurality of plug-in terminals 20 can be respectively inserted into the plurality of fixing holes 11, so that the originally disordered plug-in terminals 20 can be gathered at the fixing portion 1 and fixed, so that the male ends or female ends of the plug-in terminals 20 in the fixing holes 11 can be inserted into the corresponding female ends or male ends of the plug-in terminals 20, thereby facilitating the assembly process of the plug-in terminals 20.

[0050] like Figure 1 and Figure 2 As shown, the limiting portion 2 is connected to the fixing portion 1 and is located at the fixing portion 1 along a first direction (such as Figure 1 The side of the plug-in terminal 20 (direction a) is used to limit the lead 30 connected to the plug-in terminal 20, and the lead 30 can be limited to the limiting portion 2, and the lead 30 of the plug-in terminal 20 fixed in the fixing hole 11 can be limited to one side of the fixing portion 1 along the first direction, so that the lead 30 of the plug-in terminal 20 can be concentrated and fixed, so that the arrangement of the lead 30 is relatively simple and clear.

[0051] According to the wire management structure 10 of the embodiment of the utility model, by providing a plurality of fixing holes 11 for fixing the plug-in terminals 20 on the fixing part 1, the plurality of plug-in terminals 20 can be respectively inserted into the plurality of fixing holes 11, and the originally disordered plug-in terminals 20 can be gathered and fixed at the fixing part 1, which facilitates the assembly process of the plug-in terminals 20. Moreover, the limiting part 2 is connected to the fixing part 1 and is located on one side of the fixing part 1 along the first direction, and the lead wires 30 of the plug-in terminals 20 fixed in the fixing holes 11 can be limited to one side of the fixing part 1 along the first direction, so that the lead wires 30 of the plug-in terminals 20 can be gathered and fixed, so that the arrangement of the lead wires 30 is relatively simple and clear.

[0052] Among them, the plug-in terminal 20 is an important concept in the field of electronics and electrical appliances, and generally refers to a way of connecting electrical components. The connection method is achieved by inserting the conductor or lead 30 into the plug-in terminal 20 or inserting the plug-in terminal 20 into the socket. According to different connection methods, there are many types of plug-in terminals 20, such as screw-type plug-in terminals 20, crimp-type plug-in terminals 20, plug-in plug-in terminals 20, fence-type plug-in terminals 20, spring-type plug-in terminals 20, track-mounted plug-in terminals 20, track-type plug-in terminals 20, and H-type through-the-wall plug-in terminals 20. These plug-in terminals 20 have their own characteristics and are suitable for different application environments and needs.

[0053] The male end and the female end of the plug-in terminal 20 are two different connecting parts 2212, which have some differences in structure and function.

[0054] The male end usually refers to the end with a plug-in part, which has a contact body and a spring, and a pressing part is provided on the spring to operate the spring. Its shape can be cylindrical (round pin), square column (square pin) or flat (plug), etc. The main function of the male end is to transmit electrical signals or current from one device to another.

[0055] The female end is the part that matches the male end, and usually has a slot formed by a bottom plate, a left plate, a right plate, and a top plate. This slot is adapted to the plug-in part of the male end, and the contact relationship between the contact body and the inner wall of the slot is enhanced by the force of the spring in the slot. The function of the female end is to receive and accommodate the plug-in terminal 20 wire of the male end to ensure a tight connection between the two. There are also many types and structures of the hole for the plug-in terminal 20 in the female end, including cylindrical type (split groove, shrinkage), tuning fork type, cantilever beam type (longitudinal slot), box type (square socket) and hyperbolic wire spring socket, etc.

[0056] During the connection process, the male and female ends need to be properly matched to ensure the stability and reliability of the electrical connection. Once the male end is inserted into the slot of the female end, the contact body and the inner wall of the slot between the two will form a close contact, thereby realizing the transmission of electrical signals.

[0057] The male end and the female end of the plug terminal 20 are mutually cooperative and interdependent components, and they jointly realize the function of electrical connection. By properly selecting and using the male end and the female end, the normal operation of the electrical system and the accurate transmission of signals can be ensured.

[0058] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the limiting part 2 includes a substrate 21 and a limiting member 22 disposed on the substrate 21, and the limiting member 22 is used to limit the lead 30. It can be understood that the substrate 21 and the limiting member 22 can define a limiting groove, and the lead 30 is installed in the limiting groove, so that the lead 30 of the plug-in terminal 20 fixed in the fixing hole 11 can be limited to the limiting groove, and the lead 30 of the plug-in terminal 20 can be concentrated and fixed, so that the arrangement of the lead 30 is relatively simple and clear.

[0059] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the limiting member 22 includes a first limiting member 221, and the first limiting member 221 includes two limiting buckles 2211 spaced apart from each other. The two limiting buckles 2211 are spaced apart along the second direction (such as Figure 1The second direction is perpendicular to the first direction, and the lead 30 is located between the two limit buckles 2211. The lead 30 can be inserted into the first limit member 221 through the gap between the two spaced limit buckles 2211, and the lead 30 can be assembled into a wire harness in the first limit member 221, so that the position of the lead 30 is more reliable.

[0060] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the limit buckle 2211 includes a connection part 2212 and a wire clamping part 2213, one end of the connection part 2212 is connected to the substrate 21, and the other end extends in a direction away from the substrate 21, one end of the wire clamping part 2213 is connected to the end of the connection part 2212 away from the substrate 21, and the two wire clamping parts 2213 are located between the two connection parts 2212, and the two wire clamping parts 2213 are inclined toward each other in the direction toward the substrate 21. When the lead 30 is clamped into the wire clamping part 2213, the wire clamping parts 2213 inclined toward each other can make the clamping process of the lead 30 smoother and more convenient, and the connection part 2212 extending in a direction away from the substrate 21 can provide an installation space for the lead 30, thereby increasing the reliability of the installation of the lead 30.

[0061] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the limiting member 22 further includes a second limiting member 222, which is disposed on a side of the first limiting member 221 away from the fixing portion 1 along the first direction, and the second limiting member 222 includes two limiting protrusions 2221 spaced apart along the second direction, and the lead 30 is located between the two limiting protrusions 2221. The two limiting protrusions 2221 can limit the portion of the lead 30 located on the side of the first limiting member 221 away from the fixing portion 1 along the first direction, so that the position of the lead 30 can be more reliable.

[0062] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the limiting member 22 further includes a third limiting member 223, and the two ends of the third limiting member 223 in the length direction are respectively bonded to the two limiting protrusions 2221, and the lead 30 is located between the third limiting member 223 and the substrate 21. The two limiting protrusions 2221 can limit the third limiting member 223, which can increase the reliability of the position of the third limiting member 223. The third limiting member 223 can limit the lead 30 between the third limiting member 223 and the substrate 21, so that the position of the lead 30 is more reliable.

[0063] In some embodiments of the present invention, the third stopper 223 is a sponge. The sponge has good elasticity, and the size of the sponge can be larger than the size between the two stopper protrusions 2221, which can squeeze the lead 30 so that the lead 30 and the third stopper 223 have an interference fit, so that the position of the lead 30 is more reliable.

[0064] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the stopper 22 further includes a fourth stopper 224, which is formed as a wire hook 2241 and is located on a side of the second stopper 222 away from the first stopper 221 along the first direction, and at least a portion of the lead 30 is clamped in the wire hook 2241. The wire hook 2241 can limit at least a portion of the lead 30 located on a side of the second stopper 222 away from the first stopper 221 along the first direction at the fourth stopper 224, and can lead a portion of the lead 30 out from the wire hook 2241, so that the position of the lead 30 can be more reliable.

[0065] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, one end of the wire hook 2241 along the second direction is connected to the substrate 21 , and the other end is spaced apart from the substrate 21 , forming an accommodating space for the lead wire 30 to pass through. Along the second direction, the limiting protrusion 2221 located on the same side as the free end of the wire hook 2241 extends to the wire hook 2241, and part of the lead wire 30 entering the wire hook 2241 can be limited by the limiting protrusion 2221 located on the same side as the free end of the wire hook 2241, so that part of the lead wire 30 can enter the wire hook 2241 more smoothly; the limiting protrusion 2221 located on the same side as the fixed end of the wire hook 2241 is spaced apart from the wire hook 2241, and except for the part of the wire harness entering the wire hook 2241, other wire harnesses can be led out of the wire management structure 10 from the position of the limiting protrusion 2221 located on the same side as the fixed end of the wire hook 2241, which is spaced apart from the wire hook 2241, so that the lead wire 30 can be led to different positions, which can increase the reliability of the installation position of the lead wire 30.

[0066] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a plurality of fixing holes 11 are arranged in a third direction (such as Figure 2The plug-in terminals 20 installed on the wire management structure 10 can be spaced apart in the second direction and the plug-in terminals 20 corresponding to the plug-in terminals 20 can be spaced apart in the second direction.

[0067] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, two adjacent rows of fixing holes 11 are staggered in the first direction. When the male or female end of the plug-in terminal 20 is inserted into the fixing hole 11, it can be staggered in the first direction to avoid the plug-in terminal 20 being affected by the adjacent rows of plug-in terminals 20 when inserting into the fixing hole 11, making the insertion of the plug-in terminal 20 more convenient.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fixing part 1 is provided with a wire groove 12, and each fixing hole 11 is provided with a wire groove 12 on one side facing the limiting part 2, and the wire groove 12 is open on both sides along the first direction and one side is connected with the fixing hole 11. The part of the lead wire 30 connected to the plug-in terminal 20 inserted into the fixing hole 11 and close to the plug-in terminal 20 can enter the wire groove 12, and the lead wire 30 can be limited, thereby increasing the stability of the plug-in terminal 20 during assembly.

[0069] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a first mark 13 is provided on the bottom wall of the wire groove 12, and the first mark 13 is used to indicate the color of the plug-in terminal 20 or the lead wire 30 corresponding to the fixing hole 11. When the wire management structure 10 is matched with the plug-in terminal 20 and the wiring harness, the plug-in terminal 20 corresponding to the fixing hole 11 can be more clearly identified, thereby improving the assembly efficiency of the wire management structure 10 and the plug-in terminal 20.

[0070] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the fixing portion 1 is further provided with a second mark 14, which is an arrow for indicating the plugging direction of the plug-in terminal 20. When assembling the plug-in terminal 20 and the wire management structure 10, the insertion direction of the plug-in terminal 20 is more obvious, and the efficiency of assembling the plug-in terminal 20 and the wire management structure 10 is higher.
