Description
Technical Field
[0001] The utility model relates to the technical field of wiring terminals, in particular to a wiring harness wiring terminal protection box. Background Art
[0002] The wiring harness terminal protection box is a device used to protect the wiring harness terminal to prevent the wiring harness terminal from being exposed to the environment;
[0003] The patent application number CN220189944U discloses a wiring harness terminal protection box, which is provided with a wiring harness terminal protection box body to protect the wiring harness terminal, and the installation cover is fixed to the outside of the wiring harness terminal protection box body by connecting bolts, which can conveniently complete the fixation between the movable pad and the fixed pad, and ensure the stable connection between the movable sleeve and the fixed sleeve, so as to achieve the purpose of protecting and reinforcing the outside of the link connection part extending to the outside of the wiring harness terminal protection box body through the fixed sleeve and the movable sleeve, thereby improving the stability of line installation;
[0004] However, the steps of disassembling and assembling the protection box are relatively complicated and cumbersome. Therefore, when the terminal blocks need to be repaired or replaced, the protection box cannot be quickly disassembled and assembled, thereby reducing the efficiency of repair and replacement, and also reducing the work efficiency of the operator. In view of this, a wiring harness terminal protection box is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a wiring harness terminal protection box that can solve the problem that when the wiring terminal needs to be repaired or replaced, the protection box cannot be quickly disassembled and assembled, thereby reducing the efficiency of repair and replacement.
[0006] To achieve the above object, the utility model provides the following technical solutions: a wiring harness terminal protection box, comprising an upper shell and a lower shell, wherein both ends of the upper shell opposite to the lower shell are provided with wire body grooves, and a U-shaped sealing gasket is fixedly connected to the interior of the lower shell, and the sealing gasket can seal the gap between the upper shell and the lower shell after the upper shell and the lower shell are closed, thereby reducing the intrusion of moisture;
[0007] The wire grooves formed in the upper shell and the lower shell are both semicircular, that is, the wire grooves are circular after the upper shell and the lower shell are buckled together;
[0008] The upper shell and the lower shell are provided with a disassembly and assembly mechanism for fixing the two;
[0009] The disassembly and assembly mechanism includes a locking shaft rotatably connected to the lower housing, one end of the locking shaft extending to the interior of the lower housing;
[0010] The disassembly and assembly mechanism also includes two locking blocks arranged inside the upper shell body.
[0011] Preferably, the upper shell and the lower shell are both fixedly connected with a bearing platform, and the bearing platform is used to overlap the connection terminals, thereby preventing the connection from being loosened due to the connection terminals being in a suspended state;
[0012] The opposite ends of the supporting platforms provided on the upper shell and the lower shell are both recessed arc-shaped, thus providing sufficient accommodation space for the terminal blocks. This can prevent the supporting platforms from squeezing and damaging the terminal blocks when the upper shell and the lower shell are closed, thereby ensuring the normal operation of the terminal blocks.
[0013] Preferably, two locking ears are fixedly connected to one end of the locking shaft located inside the lower shell;
[0014] A torsion spring for resetting the locking shaft is sleeved on the locking shaft, and two torsion arms of the torsion spring are respectively fixedly connected to the surface of the locking shaft and the inner wall of the lower shell;
[0015] Furthermore, locking grooves are provided on opposite sides of the two locking blocks, and the locking grooves and the locking shafts are adapted to each other;
[0016] The inner walls of the two locking grooves are provided with limiting grooves that match the locking ears.
[0017] The limiting groove and the locking ear are both arc-shaped.
[0018] Preferably, the two locking blocks are slidably connected to a positioning shaft on one side opposite to the other, a return spring is movably sleeved on the positioning shaft, and the positioning shaft is fixedly connected to the inner wall of the upper shell;
[0019] The two ends of the return spring are respectively fixedly connected to the surface of the positioning shaft and the inner wall of the upper shell;
[0020] A first magnet and a second magnet that can be magnetically attracted to each other are respectively inlaid on opposite sides of the two locking blocks.
[0021] Preferably, a moisture absorbing layer for absorbing moisture inside the upper shell and the lower shell is fixedly connected to the inner walls thereof.
[0022] Preferably, the initial state of the locking ear on the locking shaft is a horizontal state;
[0023] The lower ends of the two locking blocks are both arc-shaped.
[0024] Compared with the prior art, the beneficial effects of the utility model are:
[0025] (1) When the upper shell and the lower shell need to be buckled together, the locking shaft is first rotated. At this time, the rotation of the locking shaft causes the locking ear to change from a horizontal state to a vertical state, and the torsion spring is stressed. At this time, the upper shell and the lower shell can be closed, so that the two locking blocks are in contact with the locking shaft. At this time, the lower ends of the locking blocks are arc-shaped, so the two locking blocks slide back to back due to the intervention of the locking shaft, and the first magnet and the second magnet are released from magnetic attraction. The reset spring is compressed. When the locking shaft enters the interior of the locking groove, the locking shaft is no longer stressed, and the torsion spring drives the locking shaft to reset, so that the locking ear is stuck in the interior of the limit groove. Then, under the restriction of the locking ear, the two locking blocks will not easily detach from the locking shaft, thereby completing the fixation of the upper shell and the lower shell. This makes the protection box more convenient and quick during disassembly and assembly, thereby improving the work efficiency and replacement speed of the operator.
[0026] (2) The moisture-absorbing layer of the wiring harness terminal protection box is made of lime, so it can effectively absorb moisture and prevent moisture from corroding the terminal. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] See also Figure 1-6 The utility model provides a technical solution: a wiring harness terminal protection box, comprising an upper shell 1 and a lower shell 2, wherein both ends of the upper shell 1 and the lower shell 2 opposite to each other are provided with wire body grooves 3;
[0040] The lower shell 2 is fixedly connected with a U-shaped sealing gasket 4 inside, and the sealing gasket 4 can seal the gap between the upper shell 1 and the lower shell 2 after they are closed, thereby reducing the intrusion of moisture;
[0041] The wire grooves 3 formed in the upper shell 1 and the lower shell 2 are both semicircular, that is, the wire grooves 3 are circular after the upper shell 1 and the lower shell 2 are buckled together;
[0042] The upper shell 1 and the lower shell 2 are provided with a disassembly and assembly mechanism for fixing the two;
[0043] The disassembly mechanism includes a locking shaft 6 rotatably connected to the lower housing 2, and one end of the locking shaft 6 extends to the interior of the lower housing 2;
[0044] The disassembly and assembly mechanism further includes two locking blocks 7 arranged inside the upper housing 1;
[0045] The disassembly and assembly mechanism provided can enable the upper shell 1 and the lower shell 2 to be quickly snapped together and installed. When the terminal blocks need to be protected, the terminal blocks can be placed inside the lower shell 2. At this time, the cables are located inside the wire groove 3. When the upper shell 1 and the lower shell 2 are snapped together, a complete protective box is formed, thereby protecting the terminal blocks and preventing them from being damaged.
[0046] Furthermore, a support platform 5 is fixedly connected to the interior of the upper shell 1 and the lower shell 2, and the support platform 5 is used to overlap the connection terminals, thereby preventing the connection from being loosened due to the connection terminals being in a suspended state;
[0047] Among them, the opposite ends of the supporting platform 5 set on the upper shell 1 and the lower shell 2 are both recessed arcs, thereby providing sufficient accommodating space for the terminal blocks. Therefore, it can be avoided that the supporting platform 5 squeezes the terminal blocks and causes damage to them when the upper shell 1 and the lower shell 2 are closed, thereby ensuring the normal operation of the terminal blocks.
[0048] Furthermore, two locking ears 10 are fixedly connected to one end of the locking shaft 6 located inside the lower housing 2;
[0049] The initial state of the locking ear on the locking shaft 6 is a horizontal state;
[0050] The locking shaft 6 is sleeved with a torsion spring 16 for resetting the locking shaft 6, and two torsion arms of the torsion spring 16 are respectively fixedly connected to the surface of the locking shaft 6 and the inner wall of the lower housing 2;
[0051] Furthermore, locking grooves 8 are provided on opposite sides of the two locking blocks 7, and the locking grooves 8 and the locking shafts 6 are adapted to each other;
[0052] Among them, the inner walls of the two locking grooves 8 are provided with limiting grooves 9 which are adapted to the locking ears 10;
[0053] Among them, the limiting groove 9 and the locking ear 10 are both arc-shaped;
[0054] By setting the limiting groove 9 and the locking ear 10 to be arc-shaped, the locking shaft 6 can rotate more smoothly and avoid mechanical jamming.
[0055] Furthermore, the two locking blocks 7 are slidably connected to the opposite sides thereof with positioning shafts 13, and the positioning shafts 13 are movably sleeved with return springs 14, and the positioning shafts 13 are fixedly connected to the inner wall of the upper housing 1;
[0056] The two ends of the return spring 14 are respectively fixedly connected to the surface of the positioning shaft 13 and the inner wall of the upper housing 1;
[0057] Wherein, a first magnet 11 and a second magnet 12 that can be magnetically attracted to each other are respectively embedded on opposite sides of the two locking blocks 7;
[0058] When it is necessary to buckle the upper shell 1 and the lower shell 2, first rotate the locking shaft 6. At this time, the rotation of the locking shaft 6 causes the locking ear 10 to change from a horizontal state to a vertical state, and the torsion spring 16 is stressed. At this time, the upper shell 1 and the lower shell 2 can be closed, so that the two locking blocks 7 are in contact with the locking shaft 6. At this time, the lower end of the locking block 7 is arc-shaped, so the two locking blocks 7 slide back to back due to the intervention of the locking shaft 6, and the first magnet 11 and the second magnet 12 are released from magnetic attraction, and the reset spring 14 is compressed. When the locking shaft 6 enters the interior of the locking groove 8, it no longer exerts force on the locking shaft 6, and the torsion spring drives the locking shaft 6 to reset, so that the locking ear 10 is stuck in the interior of the limit groove 9, and then under the restriction of the locking ear 10, the two locking blocks 7 will not easily detach from the locking shaft 6, thereby completing the fixation of the upper shell 1 and the lower shell 2;
[0059] By providing the first magnet 11 and the second magnet 12 , the two locking blocks 7 can be attracted to each other, thereby improving the stability of the lower shell 2 and the upper shell 1 after closing.
[0060] Wherein, a moisture absorbing layer 15 for absorbing moisture inside is fixedly connected to the inner wall of the upper shell 1 and the lower shell 2;
[0061] The moisture absorbing layer 15 is made of lime, so it can effectively absorb moisture and prevent moisture from corroding the connection terminals.
[0062] Working principle: when it is necessary to buckle the upper shell 1 and the lower shell 2, first rotate the locking shaft 6. At this time, the rotation of the locking shaft 6 causes the locking ear 10 to change from a horizontal state to a vertical state, and the torsion spring 16 is subjected to force. At this time, the upper shell 1 and the lower shell 2 can be closed, so that the two locking blocks 7 are in contact with the locking shaft 6. At this time, the lower end of the locking block 7 is arc-shaped, so the two locking blocks 7 are intervened by the locking shaft 6 and slide back to back, and the first magnet 11 and the second magnet 12 are released from magnetic attraction, and the reset spring 14 is compressed. When the locking shaft 6 enters the interior of the locking groove 8, it no longer exerts force on the locking shaft 6, and the torsion spring drives the locking shaft 6 to reset, so that the locking ear 10 is stuck in the interior of the limit groove 9, and then under the restriction of the locking ear 10, the two locking blocks 7 will not easily disengage from the locking shaft 6, thereby completing the fixation of the upper shell 1 and the lower shell 2.
[0063] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
