Description
A fixing structure for wiring terminals Technical Field
[0001] This utility model relates to the technical field of fixing structures, and in particular to a fixing structure for wiring terminals. Background Technology
[0002] Currently, power distribution systems such as distribution boxes and battery boxes often involve complex wiring and a large number of terminals. When the low-voltage wiring harness in the line involves data sampling, current analysis, etc., the wiring holes of a single copper busbar are often insufficient to connect and fix all the wiring harnesses. In this case, it is necessary to fix multiple terminals on each wiring hole.
[0003] Existing terminal fixing methods involve securing the wire harness to the plate using a fixing rod. The top of the fixing rod is typically U-shaped, and the annular terminal at one end of the wire harness is simply fitted onto the fixing rod for fixation. However, wire harness terminals are not limited to annular terminals; there are also non-circular hole terminals such as nickel-plated terminals and fork-shaped terminals. These terminals cannot be fitted onto the top of the fixing rod, resulting in insufficient adaptability of existing equipment. Therefore, a new fixing structure was designed to address the aforementioned problems. Summary of the Invention
[0004] The purpose of this utility model is to provide a fixing structure for wiring terminals to solve the problems mentioned in the background art.
[0005] The technical solution adopted in this utility model is:
[0006] A fixing structure for a terminal block includes: a fixing block at the top of a fixing stud, the fixing stud being fixed to a plate by a screw and a nut; a fixing component on the fixing block, the fixing component including: a groove formed on the top of the fixing block; a protrusion on the fixing block; a cover plate on the top of the fixing block; a connecting block on the top of one end of the cover plate; a crossbar passing through the protrusion and the connecting block at one end, and being fixedly connected to the protrusion and rotatably connected to the connecting block; and a snap-fit component on the fixing block for fixing the cover plate to prevent it from rotating.
[0007] In some embodiments, the inner wall of one end of the groove is designed with an arc shape.
[0008] In some embodiments, the buckle assembly further includes: a slot formed on one outer side wall of the protrusion; a slide groove formed on one end of the fixing block; a slider slidably disposed inside the slide groove; a spring disposed inside the slide groove, with both ends connected to the inner side wall of the slide groove and the slider; and the bottom end of the buckle block inserted into the inside of the slide groove and connected to the slider.
[0009] In some embodiments, the buckle assembly further includes: one end of a connecting rod rotatably connected to one end of the slider; and a push plate disposed at one end of the connecting rod and rotatably connected to the connecting rod.
[0010] In some embodiments, the snap-fit assembly further includes a sponge strip disposed on one side of the push plate.
[0011] In some embodiments, the fixing assembly further includes a torsion spring sleeved on the outer side wall of the crossbar.
[0012] In some embodiments, the top of the card block is designed with a bevel.
[0013] In some embodiments, the latching assembly further includes: a limiting rod disposed inside the slide groove, with both ends passing through the slider and the spring and connected to the inner sidewall of the slide groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This fixing structure, through the design of protrusions, connecting blocks, and crossbars, allows the cover plate to rotate. The terminal is placed inside the groove, and the rotating cover plate engages with the fixing block, preventing the terminal from moving out of the groove and thus securing it. Compared to existing devices, it can accommodate terminals of various shapes, making it more practical to use. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0025] Given that in the current technology, the existing terminals are fixed to the plate by fixing rods. The top of the fixing rods is generally U-shaped. It is only necessary to put the ring terminal at one end of the wire harness onto the fixing rod to achieve the fixing function. However, the terminals of the wire harness are not only ring-shaped, but also non-circular hole terminals such as nickel plate terminals and fork-shaped terminals. These terminals cannot be put onto the top of the fixing rod, so the existing equipment is not adaptable enough.
[0026] As shown in the attached figure, this embodiment of the utility model provides a fixing structure for a wiring terminal.
[0027] The device includes: a fixing block 12 at the top of a fixing stud 11, which can be fixed to the plate by means of a screw and a nut; a fixing component 2 on the fixing block 12, which includes: a groove 21 on the top of the fixing block 12; a protrusion 22 on the fixing block 12; a cover plate 23 on the top of the fixing block 12; a connecting block 24 on the top of one end of the cover plate 23; a crossbar 25 passing through the protrusion 22 and the connecting block 24 at one end, and being fixedly connected to the protrusion 22 and rotatably connected to the connecting block 24; and a snap-fit component 3 on the fixing block 12 to fix the cover plate 23 and prevent it from rotating.
[0028] In use, first, use the fixing stud 11 to fix it to the plate. Then, rotate the cover plate 23. The connecting block 24 at the bottom of one end of the cover plate 23 rotates on the crossbar 25, allowing the cover plate 23 to rotate and expose the groove 21 on the top of the fixing block 12. At this time, place the terminal of the wire harness inside the groove 21 (the terminal has various shapes, such as ring, Y-shaped, nickel plate, etc., but they all have one characteristic: the outer diameter of the terminal is larger than the diameter of the wire harness). Then, rotate the cover plate 23 again to make it fit with the fixing block 12. At the same time, use the snap-fit assembly 3 to snap it to the fixing block 12, fix the position of the cover plate 23 so that it will not separate from the fixing block 12, and fix the terminal inside the groove. At this time, it is more convenient and less messy when assembling the wire harness.
[0029] In some embodiments, the inner wall of one end of the groove 21 is designed with an arc shape.
[0030] The arc-shaped design makes it less likely for the outer side of the wire harness to rub against the groove when the terminal is inserted into the groove 21, thus preventing damage to the wire harness. At the same time, the symmetrical arc-shaped design forms a V-shape, which makes it easier to insert the wire harness.
[0031] In some embodiments, the buckle assembly 3 further includes: a slot 31 formed on the outer side wall of one end of the protrusion 22; a slide groove 32 formed on one end of the fixing block 12; a slider 33 slidably disposed inside the slide groove 32; a spring 34 disposed inside the slide groove 32, with both ends connected to the inner side wall of the slide groove 32 and the slider 33; and a bottom end of a locking block 35 inserted into the interior of the slide groove 32 and connected to the slider 33.
[0032] When fixing the cover plate 23, simply move the slider 33 to slide inside the groove 32, causing the two sliders 33 to move away and compress the spring 34, simultaneously moving the two locking blocks 35 away. Rotate the cover plate 23 closer to the fixing block 12, then release the slider 33. The spring 34 rebounds, pushing the slider 33 to move, causing the locking blocks 35 to slide inside the slot 31 and engage with it. This fixes the position of the cover plate 23.
[0033] In some embodiments, the buckle assembly 3 further includes: one end of a connecting rod 36 is rotatably connected to one end of the slider 33; and a push plate 37 is disposed at one end of the connecting rod 36 and is rotatably connected to the connecting rod 36.
[0034] The design of the push plate 37 and the connecting rod 36 can drive the connecting rod 36 to rotate when the push plate 37 is pushed close to the fixed block 12, so that the two sliders 33 move away from each other. This allows for simultaneous control of the two sliders 33, making operation easier.
[0035] In some embodiments, the snap-fit assembly 3 further includes a sponge strip 38 disposed on one side of the push plate 37.
[0036] The design of the 38-sponge strip not only increases comfort but also increases friction.
[0037] In some embodiments, the fixing component 2 further includes a torsion spring 26 sleeved on the outer side wall of the crossbar 25.
[0038] The design of the torsion spring 26 can cause the torsion spring 26 to tighten when the rotating cover plate 23 is in contact with the fixing block 12. Then, after the fixing of the cover plate 23 is released, the torsion spring 26 rebounds and pushes the cover plate 23 to rotate, exposing the groove 21, which makes it easier to pick up and put down the terminal.
[0039] In some embodiments, the top of the card block 35 is designed with a bevel.
[0040] The sloping design allows the locking block 35 to be squeezed and moved when the rotating cover plate 23 and the fixing block 12 are in contact, until the top of the locking block 35 passes through the slot 31. Then the spring 34 rebounds and pushes the locking block 35 to engage with the slot 31, making it easier to operate.
[0041] In some embodiments, the buckle assembly 3 further includes: a limiting rod 39 disposed inside the slide groove 32, with both ends passing through the slider 33 and the spring 34 and connected to the inner sidewall of the slide groove 32.
[0042] The design of the limiting rod 39 can prevent the spring 34 from bending when the spring 34 is compressed, thus better protecting the spring 34.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
