[0040] When it is necessary to explain, in the present application document, the side where the threading clamp is connected to the box body is the bottom surface, and the surface corresponding to the above bottom surface is the top surface.

[0041] The wire threading splint provided by the present invention comprises a frame 1 for connecting to a box body, an introduction module 2 for installing wires, and a locking device. The introduction module 2 is detachably connected to the frame 1, and the locking device is connected to the introduction module 2 so that the introduction module 2 and the frame 1 are relatively fixed when tightened, and the introduction module 2 can move relative to the frame 1 when opened.

[0042] Preferably, please refer to Figure 1-Figure 4 The frame 1 may be a rectangular frame, and the rectangular mounting plates around the frame 1 are vertically connected end to end to form a rectangular inner hole of the frame 1, and the introduction module 2 and the locking device are installed in the rectangular inner hole of the frame 1.

[0043] The frame 1 is connected to the box body. Preferably, a fixing hole 13 for installing a fixing bolt can be provided on the frame 1. The fixing bolt is used to connect the frame 1 to the box body.

[0044] The specific shape of the fixing hole 13 can be as follows Figure 4 Countersunk hole shown; cylindrical hole also possible.

[0045] Preferably, please refer to Figure 1 The number of the fixing holes 13 can be four, and the four fixing holes 13 are respectively arranged at the four corners of the rectangular frame of the frame 1.

[0046] Introducing module 2 is used to install cables. Please refer to Figure 1 and Figure 2 The introduction module 2 may include a plurality of different introduction units, and the diameter and number of the threading holes on each introduction unit are different to meet the needs of cables of different diameters and types.

[0047] The size of the frame 1 is the sum of the size of the introduction module 2 and the margin of the outer edge of the introduction module 2 from the outer edge of the frame 1, and the size of the introduction module 2 is determined according to the needs in actual production, such as the number of introduction units in the introduction module 2, the size of each introduction unit, and the distribution of the introduction units in the introduction module 2, for example Figure 1 The introduction module 2 contains ten square introduction units of the same size, and the ten introduction units in the introduction module 2 are arranged in a 2×5 array.

[0048] It should be noted here that Figure 1 The structure of the module 2 introduced in the figure is only used as an example, and is not intended to limit the structure of the module 2 introduced in the figure.

[0049] The margin between the outer edge of the introduction module 2 and the outer edge of the frame 1 needs to consider the installation space of the connection structure between the frame 1 and the box body, for example Figure 1 The middle frame 1 is connected to the box body by fixing bolts at the four corners, so the margin of the frame 1 must meet the installation and removal requirements of the fixing bolts, and sufficient installation space must be reserved.

[0050] Preferably, in order to limit the movement of the introduction module 2 in the width direction of the frame 1, in the length direction of the frame 1, a positioning protrusion can be provided on one of the inner wall of the frame 1 and the outer wall of the introduction module 2, and the other can be provided with a positioning protrusion that cooperates with the positioning groove.

[0051] The cross section of the positioning groove may be rectangular, trapezoidal, or of course any other geometric shape, as long as it meets the requirements for snapping with the positioning protrusion.

[0052] The number and length of the positioning grooves are determined according to actual production needs.

[0053] Preferably, a male corner 14 engaging with the introduction module 2 may be provided on the frame 1, and a female corner 21 cooperating with the male corner 14 may be provided on the introduction module 2. By engaging the male corner 14 with the female corner 21, the positions of the frame 1 and the introduction module 2 in the width direction of the frame 1 are relatively fixed.

[0054] Preferably, considering the structure of the introduction module 2 , the male corner 14 can be arranged on the axis in the length direction of the frame 1 .

[0055] The cross-sectional shape of the external corner 14 may be a rhombus, a rectangle, or any other geometric shape as long as it can be snap-fitted with the internal corner 21 .

[0056] When the external corner 14 is arranged on the axis of the frame 1 in the length direction, preferably, considering the need for convenient processing, the external corner 14 can be arranged as a rhombus, and the internal corner 21 can be arranged as an isosceles triangle.

[0057] Of course, two external corners 14 may also be provided, and the two external corners 14 are respectively provided on the two inner side walls in the width direction of the frame 1. Preferably, the cross-sectional shape of the external corner 14 can be set to be a triangle, and triangular grooves are provided on the two side walls of the introduction unit 2. Since the shape of the triangular grooves is regular, processing and production are relatively convenient.

[0058] The cross-sectional dimensions of the external corner 14 and the internal corner 21 are determined according to actual production needs to avoid the cross-sectional dimensions being too small to cause the limit function to fail or the cross-sectional dimensions being too large to affect the normal function of the introduction module 2.

[0059] The length of the external angle 14 also needs to be determined according to the needs of actual production, so as to avoid the limitation effect being limited due to the length being too short or the disassembly and assembly of the introduction module 2 and the frame 1 being affected due to the length being too long.

[0060] When the number of wires needs to be changed, the locking device is opened and the introduction module 2 is taken out from the frame 1; after the increase or decrease of the number of wires is completed, the introduction module 2 is installed in the frame 1 and the locking device is locked, so that the position of the introduction module 2 and the frame 1 is relatively fixed.

[0061] Therefore, compared with the wire threading splint in the prior art, the present embodiment can increase or decrease the number of wires by disassembling and assembling the introduction module 2 separately, without the need to re-disassemble the entire wire threading splint, which greatly reduces the installation time and improves the installation efficiency.

[0062] On the basis of the above embodiments, the structure of the locking device is defined, and the locking device may include a locking block 3 clamped in the frame 1 and a locking bolt 4 for driving the locking block 3 to move in the length direction of the frame 1, and an installation hole 11 for installing the locking bolt 4 is provided on the end face in the length direction of the frame 1, and the locking bolt 4 is connected to the locking block 3.

[0063] Please refer to Figure 2-Figure 6 The mounting hole 11 is arranged on the end surface of the frame 1 away from the introduction module 2 , and the shape and size of the mounting hole 11 are determined according to the shape and size of the locking bolt 4 .

[0064] The mounting hole 11 may be a cylindrical hole. Of course, the mounting hole 11 may also be designed to be any other geometric shape as long as the requirement for matching with the locking bolt 4 is met.

[0065] In this embodiment, the locking block 3 is connected to the locking bolt 4, so tightening the locking bolt 4 can fix the position of the introduction module 2 in the frame 1; loosening the locking bolt 4 can drive the locking block 3 connected thereto to move, providing space for the introduction module 2 to move in the length direction of the frame 1, and then taking out the introduction module 2 to complete the increase or decrease of the number of wires.

[0066] Considering that the working environment of the threading splint is exposed to the air and is easily infected and aged by oil stains, ultraviolet rays, etc., it is preferred to select materials with good oil resistance and UV protection to make the frame 1 and the introduction module 2 to slow down the aging rate of the material and increase the service life.

[0067] At the same time, considering that there are many cables installed in the introduction module 2 and there is a possibility of cable short circuit and fire, in order to avoid causing greater losses, it is preferred to select flame retardant materials with good fire resistance as the manufacturing materials of the frame 1 and the introduction module 2 to prevent the fire from spreading to all cables after a fire occurs somewhere on the threading clamp.

[0068] The specific manufacturing materials of the frame 1 and the introduction module 2 can be glass fiber reinforced fiber plastics with low density and high strength. Of course, ABS engineering plastics can also be selected.

[0069] On the basis of the above embodiment, the locking device may further include an insert 5 for limiting the movement of the locking bolt 4 in the length direction of the frame 1, the locking bolt 4 is provided with two positioning steps 41, and the insert 5 is provided with a groove that is clamped between the two positioning steps 41; the mounting hole 11 includes a cylindrical hole section 111 that cooperates with the positioning steps 41 and an installation groove section for installing the insert 5, the installation groove section is connected to the cylindrical hole section 111, and the installation groove section passes through the bottom surface of the frame 1 so as to install the insert 5 in the frame 1.

[0070] Since the installation groove section passes through the bottom surface of the frame 1 , the insert 5 can be conveniently installed upward from the bottom surface of the frame 1 .

[0071] The shape of the insert 5 can be a semi-cylinder with a groove, or a rectangular block with a groove, or of course any other geometric shape that meets the requirements, as long as it meets the requirements for snapping with the mounting hole 11.

[0072] Preferably, the insert 5 can be a rectangular block with a U-shaped groove at one end, and the installation groove section is a rectangular groove 112. On the one hand, the shape of the insert 5 is regular, which is convenient for processing and assembly; on the other hand, the U-shaped groove design plays a role in limiting the movement of the locking bolt 4 in the axial direction, and also facilitates the removal of the locking bolt 4 from the insert 5 during disassembly.

[0073] Based on the above embodiment, a first sealing ring fixing groove 411 for installing the first sealing ring 7 may be provided on the positioning step 41. The depth of the first sealing ring fixing groove 411 is smaller than the width of the first sealing ring 7 so as to achieve a good sealing and waterproofing effect.

[0074] Preferably, the first sealing ring 7 may be a rubber gasket having good sealing performance.

[0075] On the basis of the above embodiment, the locking block 3 may be provided with a bolt installation hole 31 for installing the locking bolt 4 and at least one spring installation hole 32 for installing the spring, and the axis of the bolt installation hole 31 and the axis of the spring installation hole 32 are both parallel to the length direction of the frame 1. Therefore, after the locking bolt 4 is tightened, the spring installed in the spring installation hole 32 will abut against the locking bolt 4 and the introduction module 2 and be compressed, thereby providing a certain support force for the locking block 3.

[0076] The diameter of the bolt mounting hole 31 is the same as the diameter of the threaded section 42 on the locking bolt 4. The bolt mounting hole 31 can be arranged at any position on the locking block 3, as long as it meets the requirement of being screwed in cooperation with the locking bolt 4.

[0077] Preferably, please refer to Figure 8 , it is required that the axis of the bolt installation hole 31 is collinear with the axis in the length direction of the frame 1, and the axis of the bolt installation hole 31 is located at half the height of the locking block 3. In this case, the bolt installation hole 31 is located at the center of the contact surface between the locking block 3 and the locking bolt 4, and the force exerted by the locking bolt 4 on the locking block 3 is more evenly distributed on the contact surface.

[0078] The size of the spring mounting hole 32 should take into account the structural strength of the locking block 3 and other factors.

[0079] Preferably, the number of the spring mounting holes 32 can be set to two, and the two spring mounting holes 32 are symmetrically distributed about the axis of the bolt mounting hole 31. Due to the symmetrical arrangement, when the locking bolt 4 drives the locking block 3 to move, the springs on both sides exert the same force on the locking block 3, which is conducive to balancing the force on the locking block 3.

[0080] It should be noted that the spring mounting hole 32 should not be too close to the bolt mounting hole 31 to avoid causing severe stress concentration in the vicinity of the two, thereby affecting the structural strength and service life of the locking block 3 .

[0081] Based on the above embodiment, a second sealing ring fixing groove 33 for installing the second sealing ring 8 can be provided on the side wall surface of the locking block 3 at one end close to the locking bolt 4. The depth of the second sealing ring fixing groove 33 is smaller than the width of the second sealing ring 8 so as to achieve a good sealing and waterproof effect.

[0082] Preferably, the second sealing ring 8 may be a rubber gasket having good sealing performance.

[0083] Based on the above embodiment, the end face of the frame 1 for connecting to the box body can be provided with an end face sealing groove 12 for installing the end face sealing ring 6. The depth of the end face sealing groove 12 is less than the thickness of the end face sealing ring 6 so as to achieve a good sealing and waterproofing effect.

[0084] The size of the end face sealing ring 6 is smaller than that of the frame 1 , and its specific size is determined according to actual needs.

[0085] In order to avoid stress concentration at right angles, preferably, fillets are provided at the four corners of the end face sealing groove 12, and the size of the fillets is determined according to the needs in actual production.

[0086] It should be noted that the first and second in the first sealing ring 7 and the second sealing ring 8 and the first sealing ring fixing groove 411 and the second sealing ring fixing groove 33 mentioned in the present application document are only used to distinguish the difference in position and do not contain any limitation on the order.

[0087] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0088] The threading splint provided by the present invention is introduced in detail above.
