Description

Technical Field

[0001] The invention relates to the technical field of engines, in particular to a self-tightening quick-connect battery grounding wire structure. Background Art

[0002] With the upgrading of emission and fuel consumption regulations for commercial vehicles, engines are now all electronically controlled to achieve better fuel consumption and emissions. The sensing, actuator, fault diagnosis and alarm functions of electronically controlled engines all require the voltage and current provided by batteries. Batteries can not only power the starter to start the engine and assist the generator in supplying power to electrical equipment, but also convert part of the electrical energy into chemical energy for storage when the voltage at the generator terminal is higher than that of the lead-acid battery, that is, for charging. The battery grounding line is an important line connecting to the engine and supplying power to the engine.

[0003] If the grounding wire is not properly connected to the battery, not only will the electronically controlled engine be unable to start or operate normally due to lack of power, but the generator will also be unable to charge the lead-acid battery normally, causing the entire vehicle electrical system to malfunction.

[0004] In addition, the existing battery grounding wire needs to be tightened manually during the tightening process, which is time-consuming and labor-intensive. Secondly, as the vehicle is running, the grounding wire is prone to loosening, which not only affects driving safety but also requires manual tightening during maintenance, which is time-consuming and labor-intensive. For this reason, we propose a self-tightening quick-connect battery grounding wire structure. Summary of the Invention

[0005] The main purpose of the present invention is to provide a self-tightening quick-connect battery grounding wire structure, which can effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A self-tightening quick-connect battery grounding wire structure, comprising:

[0008] A waterproof housing, wherein a sleeve is inserted into the interior of the housing and a grounding wire is connected to the exterior of the waterproof housing; and

[0009] A self-locking mechanism for locking the waterproof shell and the sleeve includes a base plate installed on the inner walls of both sides of the waterproof shell, and a clamping plate is set at one end of the base plate facing the sleeve through a spring, and the clamping plate corresponds to a groove opened on the outside of the sleeve.

[0010] Preferably, the upper and lower edges of the clamping plate are both arc-shaped, and the length of the clamping plate is equal to the length of the groove.

[0011] Preferably, a through hole is provided on the outside of the waterproof housing, and the grounding wire is inserted into the through hole.

[0012] Preferably, the sleeve is sleeved on the outside of the battery terminal, and a conductive sheet connected to the battery terminal is provided on the outside of the sleeve, and the grounding wire connected to the outside of the waterproof housing is in contact with the conductive sheet on the outside of the sleeve.

[0013] Preferably, both side outer walls of the waterproof housing are connected with tension bolts through threads, and one end of the tension bolt is movably connected to the outside of the bottom plate, and the other end is installed with a nut.

[0014] Preferably, a slot corresponding to the sleeve is provided at the bottom of the waterproof housing, and a waterproof rubber ring for sealing the gap between the sleeve and the waterproof housing is bonded to the inner surface of the slot.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, by setting a clamping plate inside the waterproof housing that corresponds to the groove outside the sleeve, the grounding wire can be quickly connected to the battery terminal according to the pin, reducing the difficulty of installation;

[0017] Secondly, by setting a spring between the card plate and the bottom plate, and setting a tightening screw on both sides of the waterproof shell, not only can the sleeve be automatically locked, but also elastic force compensation adjustment can be performed;

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0025] Reference Figure 1-3 As shown, a self-tightening quick-connect battery grounding wire structure includes:

[0026] A waterproof housing 1, in which a sleeve 3 is inserted, and a grounding wire is connected to the outside of the waterproof housing 1; and

[0027] A self-locking mechanism for locking the waterproof housing 1 and the sleeve 3 includes a base plate 5 installed on the inner walls on both sides of the waterproof housing 1, and a clamping plate 4 is set at one end of the base plate 5 facing the sleeve 3 through a spring, and the clamping plate 4 corresponds to a groove opened on the outside of the sleeve 3.

[0028] Reference Figure 2 The upper and lower edges of the card plate 4 are both arc-shaped, and the length of the card plate 4 is equal to the length of the groove.

[0029] Reference Figure 1 A through hole is provided on the outside of the waterproof housing 1, and the grounding wire is inserted into the through hole.

[0030] Reference Figure 2 and Figure 3 The sleeve 3 is sleeved on the outside of the battery terminal, and a conductive sheet connected to the battery terminal is provided on the outside of the sleeve 3, and the grounding wire connected to the outside of the waterproof shell 1 is in contact with the conductive sheet outside the sleeve 3.

[0031] Reference Figure 1 and Figure 2 As shown, both side outer walls of the waterproof housing 1 are connected with tension bolts 6 through threads, and one end of the tension bolt 6 is movably connected to the outside of the bottom plate 5, and the other end is installed with a nut.

[0032] Reference Figure 2 As shown, a slot corresponding to the sleeve 3 is provided at the bottom of the waterproof housing 1 , and a waterproof rubber ring 7 for sealing the gap between the sleeve 3 and the waterproof housing 1 is bonded to the inner surface of the slot.

[0033] Before use, first put the sleeve 3 on the battery terminal, then insert one end of the grounding wire into the through hole outside the waterproof shell 1, and glue the grounding wire and the waterproof shell 1 together to complete the connection of the device.

[0034] When in use, directly cover the waterproof shell 1 with the grounding wire on the outside of the sleeve 3, and make the slot at the bottom of the sleeve 3 correspond to the sleeve 3, then press the waterproof shell 1. At this time, the sleeve 3 is inserted into the slot at the bottom of the waterproof shell 1. During the insertion process, the sleeve 3 squeezes the card plate 4 on both sides of the inner wall of the waterproof shell 1, so that the card plate 4 squeezes the spring behind it. When the groove on the outside of the sleeve 3 corresponds to the card plate 4, the card plate 4 is inserted into the groove on the outside of the sleeve 3 under the action of the spring behind it, forming a waterproof shell. Figure 2 The shape shown in FIG1 is formed, thereby locking the sleeve 3. At this time, the tower iron wire connected to the waterproof shell 1 contacts the conductive sheet outside the sleeve 3, completing the connection between the grounding wire and the battery terminal.

[0035] When the elastic force of the card plate 4 needs to be adjusted, the tensioning screws on both sides of the waterproof shell 1 are manually rotated to make the tensioning screws and the waterproof shell 1 move relative to each other. At this time, the tensioning screws are squeezed toward the inside of the waterproof shell 1, causing the bottom plate 5 at one end of the spring to move toward the center, and the card plate 4 cannot move. Therefore, the spring between the card plate 4 and the bottom plate 5 is squeezed, the elastic force of the spring increases, and at the same time, the squeezing force of the card plate 4 on the sleeve 3 increases.
