Description

Technical Field

[0001] The invention relates to the technical field of wire harness connection, and in particular to a wire harness connector for a diesel engine. Background Art

[0002] The diesel engine wiring harness connector is a key component to ensure the stable operation of the diesel engine electrical system. It is usually composed of two parts: a plug and a socket. Its materials are mostly plastic and metal. The plastic part plays the role of insulation and protection, and the metal part is responsible for conductivity. It is used in many fields such as automobiles, aerospace, and consumer electronics. It has many advantages, such as convenient and fast installation and disassembly, which can improve production efficiency. Moreover, high-quality wiring harness connectors can ensure stable electrical connections, reduce failures caused by poor contact, and ensure the normal operation of equipment.

[0003] A Chinese patent document with announcement number CN216488750U discloses an injection molded connector structure for an automobile engine wiring harness assembly, including a connector body, terminal grooves being provided at equal distances on the connector body, a sealing groove being provided at the bottom of the connector body corresponding to the terminal groove, a cable being provided on the outside of the connector body, an electric wire being provided in the cable, a terminal being fixedly connected to the end of the electric wire, a waterproof plug being jointly provided at the connection between the terminal and the electric wire, an injection molded part being jointly covered on the bottom of the connector body and the outside of the end of the cable, and the injection molded part being covered on the outside of the electric wire.

[0004] In the above technology, the plug and the socket are usually connected by interference fit to ensure the sealing of the connection between the plug and the socket. However, the diesel engine will generate vibration when working. As time goes by, the plug and the socket will wear due to vibration, resulting in reduced sealing. At the same time, due to the large amount of oil and dust in the diesel engine, as the sealing is reduced, oil and dust may enter the connection between the plug and the socket, resulting in poor contact between the plug and the socket. Summary of the invention

[0005] The present invention provides a diesel engine wiring harness connector, aiming to solve the problem in the related art that wear between a plug and a socket due to vibration causes reduced sealing, thereby causing poor contact between the plug and the socket.

[0006] A diesel engine wiring harness connector, comprising a plug and a socket, wherein after the plug is plugged into the socket, an annular gap is formed between the inner peripheral wall of the plug and the outer peripheral wall of the socket, and further comprising: The first liquid capsule is sleeved on the outer peripheral wall of the socket; The anti-slip mechanism includes a magnet 1 slidably mounted on the socket along the left-right direction, a magnet 2 slidably mounted on the plug along the left-right direction, and a driving member for driving the magnet 2 to rise and fall, the liquid capsule 1 is located on the right side of the magnet 1, and the magnetism on the left side of the magnet 1 is opposite to the magnetism on the right side of the magnet 2; When the plug is inserted into the socket, magnet two is located on the left side of magnet one, and then the driving member drives magnet two to move downward so that magnet one and magnet two are at the same height, so that magnet one squeezes liquid capsule one, and then liquid capsule one seals the annular gap.

[0007] The effect is as follows: first, an annular gap is formed between the inner circumferential wall of the plug and the outer circumferential wall of the socket, and then a liquid capsule 1 is sleeved on the outer circumferential wall of the socket. Since the outer circumferential wall of the liquid capsule 1 does not contact the inner circumferential wall of the plug when the liquid capsule 1 is not squeezed, when the plug is inserted into the socket, the resistance is small, which is convenient for installation. In addition, a magnet 1 and a magnet 2 are respectively arranged on the socket and the plug. After the plug is inserted into the socket, the magnet 2 is located on the left side of the magnet 1, and the magnetism of the left end face of the magnet 1 and the magnetism of the right end face of the magnet 2 are set to opposite magnetism. Then, the magnetic force is used to push the magnet 1 and the magnet 2 away from each other, so that the magnet 1 squeezes the liquid capsule 1, thereby squeezing the liquid in the liquid capsule 1 to other parts of the liquid capsule 1, so that the outer circumferential wall of the liquid capsule 1 abuts against the inner circumferential wall of the plug, thereby achieving the blocking of the annular gap. At the same time, since the liquid capsule 1 is made of a flexible material as a whole, when the plug and the socket vibrate, the friction between the plug and the socket can be reduced, thereby reducing the wear between the plug and the socket due to vibration.

[0008] Preferably, a track groove one is provided on the socket, a magnet one is slidably installed in the track groove one, a protrusion one is provided on the liquid capsule one, and the magnet one is connected to the protrusion one.

[0009] The effect is that by arranging an additional protrusion 1 on the liquid capsule 1 and making the protrusion 1 and the liquid capsule 1 connected to each other, when the magnet 1 squeezes the protrusion 1, the liquid can be squeezed from the protrusion 1 into the liquid capsule 1, so that the liquid capsule 1 can be expanded to a larger range, thereby improving the sealing effect.

[0010] Preferably, the protrusion one is provided with an elastic member three for expanding the protrusion.

[0011] The effect is that by arranging an elastic member three in the protrusion one to expand the protrusion, when the plug is separated from the socket, after the magnet one loses its magnetic force, the elastic member three can expand the protrusion, so that the liquid in the liquid capsule one flows back into the protrusion one, and then the outer peripheral wall of the liquid capsule one is separated from the contact with the inner peripheral wall of the plug, thereby facilitating the detachment of the plug from the socket.

[0012] Preferably, the driving member includes a push plate connected to the top of magnet two and a locking assembly for locking the push plate. A slide groove running through the upper and lower parts is provided on the plug. The push plate is slidably installed in the slide groove along the upper and lower directions. When the plug is inserted into the socket, the push plate moves downward. When magnet one and magnet two are at the same height, the locking assembly locks the push plate in the slide groove.

[0013] The effect is that by setting the magnet 2 to be liftable, when the plug is inserted into the socket, the magnet 2 and the magnet 1 can be moved away from each other, so that the magnet 2 can be moved from the right side of the magnet 1 to the left side of the magnet 1. At the same time, by setting a locking assembly, the magnet 1 is locked after being at the same height as the magnet 2, so that the magnet 2 and the magnet 1 are always subjected to repulsive magnetic forces.

[0014] Preferably, the locking assembly includes a locking block slidably installed on the push plate along the left and right directions, an elastic member 1 is installed between the locking block and the push plate, a step plate is arranged in the slide groove, and when magnet 1 and magnet 2 are at the same height, the locking block pops out from the push plate and abuts against the step plate.

[0015] The effect is that two locking blocks are slidably installed on the push plate, and a step plate is arranged in the slide groove. When the locking block is located below the step plate, the locking block is popped out by the elastic member, so that the locking block and the step plate are clamped, thereby locking the push plate.

[0016] Preferably, a second elastic member is provided between the push plate and the plug, and the second elastic member applies an upward elastic force to the push plate.

[0017] The effect is that by setting the elastic member 2 between the push plate and the plug, when the magnet 2 is disengaged from the track groove 1, the locking block is first retracted into the push plate, and then the push plate moves upward under the push of the elastic member 2, so that the magnet 2 is disengaged from the track groove 1.

[0018] Preferably, the second magnet and the push plate are slidably matched in the left-right direction, and a second liquid capsule is provided on the inner peripheral wall of the plug, and the second liquid capsule is located on the left side of the second magnet.

[0019] Preferably, a second protrusion is provided on the second liquid capsule, and the second magnet is connected to the second protrusion of the second liquid capsule.

[0020] Preferably, an elastic member 4 is provided inside the protruding portion 2 to expand the protruding portion 2.

[0021] Preferably, two groups of the anti-slipping mechanisms are symmetrically arranged, and the two groups of anti-slipping mechanisms are respectively located at the upper and lower sides of the socket.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. Liquid capsule 1 and liquid capsule 2 are respectively arranged on the socket and the plug, and the inside of liquid capsule 1 and liquid capsule 2 is not filled with liquid, and an annular gap is arranged between the outer peripheral wall of the socket and the inner peripheral wall of the plug. Since liquid capsule 1 and liquid capsule 2 that are not squeezed by magnet 1 and magnet 2 do not block the annular gap, when the plug is plugged into the socket, the resistance between the plug and the socket is small, which is convenient for installation. Moreover, since liquid capsule 1 and liquid capsule 2 are both made of flexible materials, when the plug and the socket vibrate, the friction between the plug and the socket can be reduced, thereby reducing the wear between the plug and the socket due to vibration.

[0023] 2. By arranging magnet 1 and magnet 2 on the socket and the plug respectively, and the magnetism of the left end face of magnet 1 is opposite to the magnetism of the right end face of magnet 2, after the plug is inserted into the socket, when magnet 1 and magnet 2 are gradually at the same height, magnet 1 and magnet 2 move away from each other under the action of magnetic force, and squeeze the protrusions 1 and 2 on the liquid capsule 1 and the liquid capsule 2 respectively, so that the liquid capsule 1 and the liquid capsule 2 located in the annular gap expand, and the annular gap is blocked. At the same time, magnet 1 and magnet 2 also provide a force between the plug and the socket through the elastic member 3 and the elastic member 4 respectively to always bring the two closer to each other, thereby improving the reliability of the connection between the plug and the socket.

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figure 1 , Figure 2 and Figure 7 As shown, a diesel engine wiring harness connector according to an embodiment of the present invention comprises a plug 1, a socket 2, a liquid capsule 1 3, a liquid capsule 2 4 and two sets of anti-slipping mechanisms 5. After the plug 1 is inserted into the socket 2, an annular gap 6 is formed between the inner circumferential wall of the plug 1 and the outer circumferential wall of the socket 2. The liquid capsule 1 3 is sleeved on the outer circumferential wall of the socket 2, and the liquid capsule 2 4 is installed on the inner circumferential wall of the plug 1. The two sets of anti-slipping mechanisms 5 are respectively located on the upper and lower sides of the socket 2.

[0035] When plugging the plug 1 into the socket 2, the worker first holds the plug 1 and plugs it into the plug 1 from right to left. Since the liquid in the liquid capsule 2 4 and the liquid capsule 1 3 is not full, when the liquid capsule 2 4 contacts the liquid capsule 1 3, the liquid capsule 2 4 and the liquid capsule 1 3 will be deformed, so that the liquid capsule 2 4 passes through the liquid capsule 1 3 from the outside of the liquid capsule 1 3, and then is sleeved on the socket 2. After the plug 1 is plugged into the socket 2, the two sets of anti-slip mechanisms 5 squeeze the liquid capsule 1 3 and the liquid capsule 2 4, so that the unsqueezed areas of the liquid capsule 1 3 and the liquid capsule 2 4 expand, and then the annular gap 6 is blocked to achieve the sealing between the plug 1 and the socket 2.

[0036] like Figure 1 and Figure 2 As shown, the socket 2 includes a base 21 and two conductive rings (not shown in the figure). Two right-end penetrating plug-in slots are respectively provided on the right end surface of the base 21 along the front-to-back direction, and the two conductive rings are respectively installed in the two plug-in slots.

[0037] like Figure 1 and Figure 2As shown, the plug 1 includes a base 11, a cable 12, two conductive posts 13 and an annular shell 14. The cable 12 is installed at the right end of the base 11. The two conductive posts 13 are respectively installed on the left end surface of the base 11 along the front-to-back direction, and the two conductive posts 13 and the two conductive rings correspond to each other one by one. The cable 12 is electrically connected to the two conductive posts 13. The left and right ends of the annular shell 14 are penetrated, the right end of the annular shell 14 is installed on the left end surface of the base 11, and the two conductive posts 13 are both located inside the annular shell 14.

[0038] like Figure 3-Figure 7 As shown, the liquid capsule 3 is sleeved on the outer peripheral wall of the base 21, and the upper and lower end surfaces of the base 21 are provided with a track groove 1. The left end surface of the liquid capsule 3 is provided with two protrusions 31 extending into the track groove 1. The protrusion 31 and the liquid capsule 3 are connected to each other. The right end surface of the protrusion 31 is fixedly connected to the base 21. An elastic member 32 is provided inside the protrusion 31. The elastic member 32 is a compression spring 3. The right end of the compression spring 3 is fixedly connected to the right end of the protrusion 31, and the left end of the compression spring 3 is fixedly connected to the left end of the protrusion 31. The liquid capsule 3 The inner peripheral wall of 3 is fixedly connected with the outer peripheral wall of base 21. When the anti-slip mechanism 5 squeezes the protrusion 31, the liquid in the protrusion 31 can be squeezed to the position of the liquid capsule 3 located in the annular gap 6, so that the position of the liquid capsule 3 located in the annular gap 6 is expanded by the liquid, and then the liquid capsule 3 blocks the right side of the annular gap 6. When the anti-slip mechanism 5 does not squeeze the protrusion 31, the compression spring 3 is of the original length. At this time, the protrusion 31 is in an open state, and the liquid in the liquid capsule 3 flows into the protrusion 31, so that the annular gap 6 is opened.

[0039] like Figure 3-Figure 7 As shown, the liquid capsule 24 is installed on the inner peripheral wall of the shell 14, the outer peripheral wall of the liquid capsule 24 is fixedly connected to the inner peripheral wall of the shell 14, and the upper and lower end surfaces of the shell 14 are both installed with bosses 215, and the bosses 215 are provided with a slide groove 16 running through the upper and lower ends. The right end surface of the liquid capsule 24 is provided with two protrusions 2141 extending into the slide groove 16, and the protrusions 2141 and the liquid capsule 214 are connected to each other. The left end surface of the protrusions 2141 is fixedly connected to the shell 14, and the inside of the protrusion 11 is provided with an elastic member 42, and the elastic member 42 is a compression spring 4, and the left end of the compression spring 4 is passed through The left end of the protrusion 41 is fixedly connected, and the right end of the compression spring 4 is fixedly connected to the right end of the protrusion 41. When the anti-slip mechanism 5 squeezes the protrusion 41, the liquid in the protrusion 41 can be squeezed into the liquid capsule 4, so that the part of the liquid capsule 4 located in the annular gap 6 is expanded by the liquid, and then the liquid capsule 4 blocks the left side of the annular gap 6. When the anti-slip mechanism 5 does not squeeze the protrusion 41, the compression spring 4 is at its original length. At this time, the protrusion 41 is in an open state, and the liquid in the liquid capsule 4 flows into the protrusion 41, thereby opening the annular gap 6.

[0040] like Figure 1-Figure 3 As shown, the two sets of anti-slipping mechanisms 5 are symmetrically arranged in the up-down direction, and the two sets of anti-slipping mechanisms 5 are respectively located at the upper and lower sides of the base 21. The following description takes the anti-slipping mechanism 5 on the upper side of the base 21 as the orientation reference. The anti-slipping mechanism 5 includes a magnet 51, a magnet 52 and a driving member. The magnet 51 is slidably installed in the track groove 1 along the left-right direction. The track groove 1 is provided with a side groove extending in the front-rear direction, so that the cross-section of the track groove 1 along the front-rear direction is an inverted "T" shape. The front and rear end surfaces of the magnet 51 are located at the bottom. A boss one is installed, the size of which is matched with the side groove, and the boss one is slidably installed in the side groove. The right end face of magnet one 51 is fixedly connected to the left end face of protrusion one 31, and magnet two 52 is slidably installed in the slide groove 16 along the left and right directions. A connecting plate 43 is fixedly installed on the right end face of protrusion one 31, and the left end face of magnet two 52 is slidably installed on the connecting plate 43 along the up and down directions. The magnetism on the left side of magnet one 51 is opposite to the magnetism on the right side of magnet two 52, and a driving member is arranged in the slide groove 16 for driving magnet two 52 to rise and fall.

[0041] Before plug 1 is inserted into socket 2, the driving member retracts magnet 2 52 upward into slide groove 16, and then the worker manually aligns conductive column 13 with the conductive ring, and moves plug 1 to the left to plug into socket 2. At this time, after the inner peripheral wall of liquid capsule 2 4 contacts the outer peripheral wall of liquid capsule 1 3, since the liquid in liquid capsule 1 3 and liquid capsule 2 4 does not fill liquid capsule 1 3 and liquid capsule 2 4, liquid capsule 1 3 and liquid capsule 2 4 will be deformed, so that liquid capsule 2 4 passes through liquid capsule 1 3 from the outside of liquid capsule 1 3, and then moves to the left side of liquid capsule 1 3, and is set on On the outer peripheral wall of the base 1 21, when the right end face of the base 1 21 abuts against the left end face of the base 2 11, the driving member moves the magnet 2 52 downward and inserts it into the track groove 1. Since the magnetism on the left side of the magnet 1 51 is opposite to the magnetism on the right side of the magnet 2 52, the magnet 2 52 and the magnet 1 51 move to the left and right directions respectively under the action of the magnetic force, and then squeeze the liquid capsule 2 4 and the liquid capsule 1 3 respectively, so that the unsqueezed areas of the liquid capsule 1 3 and the liquid capsule 2 4 expand, thereby realizing the sealing of the annular gap 6 between the inner peripheral wall of the shell 14 and the outer peripheral wall of the base 21.

[0042] like Figure 2-Figure 6As shown, the driving member includes a push plate 53 and a locking assembly 54. The push plate 53 is slidably installed in the slide groove 16 along the up and down direction. A track groove 531 is provided on the lower end surface of the push plate 53. The cross section of the track groove 531 along the front and rear direction is "T" shaped. A boss 3 adapted to the track groove 531 is installed on the top of the magnet 52. The boss 3 is slidably installed in the track groove 531 along the left and right direction. A limit plate is installed at the bottom end of the slide groove 16. A plurality of elastic members are arranged between the upper end surface of the limit plate and the lower end surface of the push plate 53. Part 2 55, elastic part 2 55 is compression spring 2, and the two ends of compression spring 2 are respectively fixed to the upper end surface of the limit plate and the lower end surface of the push plate 53. When the compression spring 2 is in its original length, the push plate 53 is located at the upper end of the slide groove 16, so that the magnet 2 52 is retracted into the slide groove 16, and then when the plug 1 is inserted into the socket 2, the magnet 2 52 can pass over the magnet 1 51 from above the magnet 1 51, thereby moving to the left side of the magnet 1 51. The locking assembly 54 is arranged on the push plate 53, and is used to lock the push plate 53 and the shell 14.

[0043] When the plug 1 is inserted into the socket 2, the worker presses the push plate 53 to move downward. The push plate 53 moves downward, driving the magnet 2 52 to move downward. At the same time, the compression spring 2 is compressed and stores force. When the magnet 2 52 enters the track groove 1, the locking assembly 54 is used to lock the push plate 53 and the shell 14. When the plug 1 is removed from the socket 2, the locking assembly 54 first unlocks the push plate 53 and the shell 14, and then the compression spring 2 is released and restores its original length, and pushes the push plate 53 to move upward. The push plate 53 moves upward, driving the magnet 2 52 to move upward. When the magnet 2 52 shrinks into the slide groove 16, the shell 14 is manually pulled to the right to disengage the plug 1 from the socket 2.

[0044] like Figure 2-Figure 8 As shown, the locking assembly 54 includes two locking blocks 541 slidably mounted on the push plate 53. The upper end surface of the push plate 53 is provided with a boss 532 extending upward. The top of the slide groove 16 is provided with a step plate 17. The boss 532 is provided with two "L"-shaped mounting grooves 533. The two mounting grooves 533 are symmetrically arranged along the left and right directions. The upper ends of the vertical sections of the two mounting grooves 533 both penetrate the boss 532. The horizontal sections of the two mounting grooves 533 respectively penetrate the left and right end surfaces of the boss 532. The locking block 541 is composed of a horizontal section and a vertical section. The whole is "L" shape, the two locking blocks 541 are symmetrically arranged in the two installation grooves 533 along the left and right directions, the vertical sections of the locking blocks 541 extend outward and extend out of the boss four 532, the horizontal sections of the locking blocks 541 are slidably installed in the horizontal sections of the installation grooves 533 along the left and right directions, and an elastic member 542 is installed between the horizontal sections of the two locking blocks 541 and the boss four 532. The elastic member 542 is a compression spring 1, and the compression spring 1 is used to make the horizontal section of the locking block 541 extend out from the boss four 532. The left and right ends of the horizontal sections of the two locking blocks 541 are provided with inclined surfaces 543.

[0045] In the initial state, the two locking blocks 541 are both extended from the boss four 532, and the two locking blocks 541 are both located on the upper side of the step plate 17. When the worker presses the boss four 532 to move downward, the inclined surfaces 543 of the two locking blocks 541 first abut against the step plate 17, and then as the boss four 532 continues to move downward, the two locking blocks 541 are pressed by the step plate 17 through the inclined surfaces 543 and thus retract into the boss four 532. At the same time, the compression spring is compressed and stored. After the locking block 541 moves to the bottom of the step plate 17, the two locking blocks 541 are disengaged from the abutment with the step plate 17, and the compression spring 1 is released and pushes the locking block 541 to extend out from the boss 4 532. Since the compression spring 2 has been compressed and accumulated force at this time, the upper end surface of the horizontal section of the locking block 541 abuts against the step plate 17, thereby forming a card connection between the locking block 541 and the step plate 17. At the same time, the magnet 2 52 has entered the track groove 1 and is at the same height as the magnet 2 52.

[0046] The specific working principle of the present invention is: Before the plug 1 is inserted into the socket 2, the upper end of the boss four 532 is located above the step plate 17, and the two locking blocks 541 are both located on the upper side of the step plate 17. At this time, the compression spring two makes the upper end surface of the push plate 53 abut against the lower end surface of the step plate 17, thereby retracting the magnet two 52 into the slide groove 16.

[0047] When plugging the plug 1 into the socket 2, the worker aligns the conductive column 13 with the conductive ring, and then holds the shell 14 and moves it toward the base 21. When the inner wall of the liquid capsule 24 contacts the outer wall of the liquid capsule 3, since the liquid capsule 13 and the liquid capsule 24 are not squeezed at this time, part of the liquid in the liquid capsule 13 and the liquid capsule 24 is located in the protrusion 131 and the protrusion 241 respectively. Therefore, the liquid capsule 13 and the liquid capsule 24 will be deformed, so that the liquid capsule 24 passes through the liquid capsule 13 from the outside of the liquid capsule 13, and then moves to the left side of the liquid capsule 13. When the right end face of the base 21 abuts against the left end face of the base 211, the plug 1 has been inserted into the socket 2.

[0048] After the plug 1 is inserted into the socket 2, the two protrusions 4 on the housing 14 are manually pressed to bring them closer to each other. When the inclined surface 543 of the locking block 541 abuts against the step plate 17, the locking block 541 is pressed by the step plate 17 and retracts into the protrusion 4. At the same time, the compression spring 1 is compressed and stores force. When the locking block 541 passes over the step plate 17, the locking block 541 extends out from the protrusion 4 under the push of the compression spring 1. At this time, a card connection is formed between the horizontal section of the locking block 541 and the step plate 17. At the same time, in the process of the two protrusions 4 approaching each other, the two magnets 2 52 are both pulled out from the sliding The magnets 51 and 52 gradually extend out of the groove 16 and are respectively inserted into the two track grooves 1 at the upper and lower ends of the base 1 21. When the magnet 2 52 gradually enters the track groove 1, the magnet 1 51 and the magnet 2 52 begin to move away from each other under the action of the magnetic force, and respectively squeeze the protrusion 1 31 and the protrusion 2 41, so that the liquid in the protrusion 2 41 and the protrusion 1 31 flows into the unsqueezed areas of the liquid capsule 1 3 and the liquid capsule 2 4, respectively, and then the areas where the liquid is filled in the liquid capsule 1 3 and the liquid capsule 2 4 expand, and finally the annular gap 6 between the inner peripheral wall of the shell 14 and the outer peripheral wall of the base 21 is sealed.

[0049] When separating the plug 1 from the socket 2, pinch the vertical sections of the two locking blocks 541 on the same protrusion four to move the two locking blocks 541 closer to each other. When the horizontal sections of the locking blocks 541 are out of contact with the step plate 17, the compression spring 2 is released and pushes the push plate 53 to move upward. At the same time, the magnet 2 52 withdraws from the track groove 1 until the push plate 53 contacts the step plate 17. Then the worker pulls the housing 14 to the right, and finally separates the plug 1 from the socket 2.

[0050] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention.
