Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, and specifically relates to a protective engine wire harness assembly. Background Technique

[0002] The engine wire harness assembly is the nerve transmission system of the engine, and its function is to transmit or exchange the power supply or data signal of the electrical system.

[0003] Publication No. CN217281966U discloses an engine wire harness assembly. By the combined use of a wire sleeve, a corrugated pipe, a compression spring, a curved pressing plate and a pointed protrusion, the exposed condition of the branch joint of the wire harness is avoided. Through the combined use of the wire sleeve and the corrugated pipe, the branch joint of the wire harness is completely wrapped, and through the elastic extrusion of the compression spring on the curved pressing plate, the pointed protrusion realizes the clamping effect on the corrugated pipe, thereby avoiding the condition that the wire sleeve falls off. Then, through the combined use of the connecting shell and the pressing block, not only the wire harness is fixed, but also the extrusion damage is reduced. However, the following problems still exist in the actual use process of this patent:

[0004] Although this engine wire harness assembly is fixed by the combined use of the connecting shell and the pressing block, and the extrusion damage is also reduced, during the long-term use process, the vibration force generated by the generator is likely to cause the bolts to loosen, resulting in the phenomenon that the connecting shell falls off. The wire harness assembly falls off at the connection or dust enters, thus affecting the normal use of the wire harness.

[0005] A protective engine wire harness assembly is proposed to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a protective engine wire harness assembly to solve the problem that in the current background technology, through the combined use of the connecting shell and the pressing block, not only the wire harness is fixed, but also the extrusion damage is reduced. However, during the long-term use process, the vibration force generated by the generator is likely to cause the bolts to loosen, resulting in the phenomenon that the connecting shell falls off. The wire harness assembly falls off at the connection or dust enters, thus affecting the normal use of the wire harness.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A protective engine wire harness assembly includes a limiting mechanism, and both the left and right sides of the limiting mechanism are fixedly connected to the top of the connecting sleeve;

[0008] Both sides of the limiting mechanism are provided with a protection mechanism, and a wire harness main body installed inside the protection mechanism;

[0009] Also included are:

[0010] The limiting mechanism includes a limiting sleeve, and joints are symmetrically clamped and connected to both sides of the central position inside the limiting sleeve. One end of the limiting sleeve is adhesively connected with a limiting cover;

[0011] Wherein, sliding sleeves are symmetrically and fixedly connected to the upper and lower ends of the limiting sleeve near the limiting cover side. A limiting groove is opened at the central position inside the sliding sleeve;

[0012] Wherein, a blocking rod is slidably connected inside the limiting groove. One end of the blocking rod penetrates through the sliding sleeve and is inserted and connected with the limiting cover. A Z-shaped block is slidably connected inside the other end of the blocking rod.

[0013] Preferably, buttons are adhesively connected to both the left and right sides of the Z-shaped block, and the outer sides of the buttons are slidably connected with the sliding sleeve.

[0014] Preferably, a first spring is fixedly connected to one end inside the button, and one end of the first spring is fixedly connected with the blocking rod.

[0015] Preferably, the protection mechanism includes a connecting sleeve. One end of the connecting sleeve is fixedly connected with the joint, and a corrugated pipe is fixedly connected to the other end of the connecting sleeve. One end of the total wire harness body penetrates through the corrugated pipe and is fixedly connected with the joint.

[0016] Preferably, an annular plate is fixedly connected to the outer side of the connecting sleeve. A groove is opened on one side of the annular plate. A guide rod is fixedly connected inside the groove. A second spring is sleeved at the central position outside the guide rod. Both ends of the second spring are adhesively connected with sliders.

[0017] Preferably, the inside of the slider is slidably connected with the guide rod. One end of the slider is rotatably connected with a connecting rod, and the other end of the connecting rod far from the slider is rotatably connected with a buffer ring.

[0018] Preferably, cylinders are fixedly connected to both ends of one side of the buffer ring. A fixing sleeve is sleeved outside the cylinders.

The inside of the damping particles is inserted and connected with the cylinder.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: For this protective engine wire harness assembly, by setting the limiting mechanism, the joints of the total wire harness body can be limited, avoiding the phenomenon that the total wire harness body falls off at the connection or dust enters, thereby affecting the signal transmission of the total wire harness body. By setting the protection mechanism, both ends of the total wire harness body can be protected from being damaged by impact or bending force during use and other processes. The specific content is as follows:

[0020] 1. By setting a limiting mechanism, the joint of the total wire harness body can be limited, preventing the total wire harness body from falling off at the connection or dust from entering, thus affecting the signal transmission of the total wire harness body. By utilizing the limiting effect of the stop rod on the limiting cover, the separation of the limiting sleeve and the limiting cover is avoided, thereby improving the connection stability of the total wire harness body. When the button is pressed to drive the first spring to compress, the cooperation between the button and the Z-shaped block is utilized to drive the stop rod to move outwards, thus releasing the limitation of the stop rod on the limiting cover, making it convenient to disassemble the total wire harness body;

[0021] 2. By setting a protection mechanism, both ends of the total wire harness body can be protected from being damaged by impact or bending force during use. When the end of the total wire harness body is impacted, a part of the impact force is reduced after the third spring is compressed, and then the third spring causes the cylinder to rise and reset. The cylinder rises to contact the damping particles to absorb the rebound force, thus playing a buffering role. The slider is driven by the connecting rod to move on the surface of the guide rod, and a part of the impact force is reduced after the second spring is compressed, thereby protecting the total wire harness body and reducing the damage caused by impact.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-6 , the present invention provides a technical solution: a protective engine wire harness assembly, including a limit mechanism 1, and both the left and right sides of the limit mechanism 1 are fixedly connected to the top of the connecting sleeve 201; both sides of the limit mechanism 1 are provided with a protection mechanism 2, and a total wire harness body 203 installed inside the protection mechanism 2; the limit mechanism 1 includes a limit sleeve 101, and both sides of the center position inside the limit sleeve 101 are symmetrically clamped and connected with connectors 102. One end of the limit sleeve 101 is fitted and connected with a limit cover 103, and the inner walls of the limit sleeve 101 and the limit cover 103 are both in contact with the connector 102, which can play a role in limiting the connector 102;

[0031] On the upper and lower ends of the side of the limit sleeve 101 close to the limit cover 103, sliding sleeves 104 are symmetrically fixedly connected. A limit groove 105 is opened at the center position inside the sliding sleeve 104; a stop bar 106 is slidably connected inside the limit groove 105. One end of the stop bar 106 passes through the sliding sleeve 104 and is inserted into the limit cover 103. A Z-shaped block 107 is slidably connected inside the other end of the stop bar 106. By using the cooperation between the Z-shaped block 107 and the button 108, the stop bar 106 can be driven to move up and down inside the sliding sleeve 104;

[0032] Both the left and right sides of the Z-shaped block 107 are in contact with the button 108. The outside of the button 108 is slidably connected with the sliding sleeve 104. One end inside the button 108 is fixedly connected with a first spring 109. One end of the first spring 109 is fixedly connected with the stop bar 106. The outside of the button 108 is slidably connected with the limit sleeve 101;

[0033] The protection mechanism 2 includes a connecting sleeve 201. One end of the connecting sleeve 201 is fixedly connected to the joint 102, and the other end of the connecting sleeve 201 is fixedly connected to a corrugated pipe 202. One end of the total wire harness body 203 penetrates through the corrugated pipe 202 and is fixedly connected to the joint 102. By providing the corrugated pipe 202, the total wire harness body 203 can be protected;

[0034] An annular plate 204 is fixedly connected to the outer side of the connecting sleeve 201. A groove 205 is formed on one side of the annular plate 204. A guide rod 206 is fixedly connected to the inside of the groove 205. A second spring 207 is sleeved at the central position of the outer side of the guide rod 206. Both ends of the second spring 207 are in fitting connection with sliders 208. By using the fact that the second spring 207 is compressed to subtract part of the impact force, the total wire harness body 203 is protected, and the damage caused by impact is reduced;

[0035] The inside of the slider 208 is slidably connected to the guide rod 206. One end of the slider 208 is rotatably connected to a connecting rod 209. The end of the connecting rod 209 away from the slider 208 is rotatably connected to a buffer ring 210. Both ends on one side of the buffer ring 210 are fixedly connected to cylinders 211. The more the number of cylinders 211, the better the buffering effect. A fixing sleeve 212 is sleeved on the outer side of the cylinders 211. The bottom end of the fixing sleeve 212 is fixedly connected to the annular plate 204. A third spring 213 is fixedly connected to the bottom end inside the fixing sleeve 212. One end of the third spring 213 is in fitting connection with the cylinder 211. A damping particle 214 is fixedly connected to the top end inside the fixing sleeve 212. The inside of the damping particle 214 is inserted and connected with the cylinder 211. By providing the damping particle 214, the rebounding force of the third spring 213 can be absorbed, and a good buffering effect can be achieved.

[0036] Working principle: Before using this kind of protective engine wire harness assembly, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 6 As shown, first, after docking the joints 102 of the two total wire harness bodies 203, the limit sleeve 101 and the limit cover 103 are respectively sleeved from both ends of the connection part to make them snap together. When the end of the total wire harness body 203 is impacted, part of the impact force is subtracted by the compression of the third spring 213. Then, the third spring 213 causes the cylinder 211 to rise and reset. The cylinder 211 rises and contacts the damping particle 214 to absorb the rebounding force, thus playing a buffering role. The connecting rod 209 drives the slider 208 to move on the surface of the guide rod 206. By using the fact that the second spring 207 is compressed to subtract part of the impact force, the total wire harness body 203 is protected, and the damage caused by impact is reduced;

[0037] Secondly, when it is necessary to remove the overall harness cost body 203, while pressing the button 108 to drive the first spring 109 to compress, the cooperation between the button 108 and the Z-shaped block 107 is utilized to drive the retaining rod 106 to move outwards, thereby releasing the limit of the retaining rod 106 on the limit cover 103, and facilitating the disassembly of the overall harness cost body 203.
