Description

Technical Field

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

[0002] Wire harness connection is used to reliably connect two wire harnesses to ensure good electrical conductivity. Common connection methods used by operators include terminal connection and tape winding connection. There are many types of terminal blocks, such as spring terminals, bolt terminals and push terminals. The connection between wire harnesses usually involves connecting multiple wires at the same time, and is usually used in automobiles, household appliances and electronic instruments. When the connection between wire harnesses is in a long-term vibration environment, in order to prevent the wire harness from falling off, it is necessary to set an anti-falling structure for the connection device of the wire harness, such as the wire harness in the car.

[0003] A Chinese patent document with authorization announcement number CN108336544B discloses a wiring harness connector, including a first base, a first pressure plate, a first conductive joint, a second base, a second pressure plate and a second conductive joint. The first base and the second base are used to connect the wiring harness, the first pressure plate is used to press on the wiring harness in the first base, and the second pressure plate is used to press on the wiring harness in the second base. The first conductive joint is electrically connected to the wiring harness in the first base, and the second conductive joint is electrically connected to the wiring harness in the second base. A card hole is fixedly provided on the side wall of the first base, and a buckle is fixedly provided on the side wall of the second base. The card hole and the buckle cooperate to form an anti-slip structure for fixing the rear openings of the first base and the second base.

[0004] However, the anti-drop structure formed by the buckle and the hole is easy to fall off during vibration. At the same time, it is easy for non-professionals to press the buckle, causing the buckle to fall out of the hole, resulting in misoperation. If it is not installed in place, it can still conduct electricity, but it is very unstable and can easily become loose or accidentally disengaged. In order to reduce misoperation by non-professionals, it is usually necessary to increase the strength of the buckle to make it difficult to press. However, such a setting requires professionals to use tools to pry it when repairing, making disassembly very inconvenient. Summary of the invention

[0005] The present invention provides a wiring harness connection device, aiming to solve the problem in the related art that the snap connection is difficult to disassemble due to the excessively high strength adopted.

[0006] A wiring harness connection device of the present invention comprises a male head and a female head matched with the male head, wherein a positioning buckle for clamping the female head is fixedly arranged on the male head; the positioning buckle comprises a first buckle and a second buckle, and a plurality of mounting grooves for installing the first buckle or the second buckle are provided on the male head, and a first buckle or a second buckle is correspondingly installed in each mounting groove, and the position for installing the first buckle is a first clamping position, and the position for installing the second buckle is a second clamping position; one end of the female head for plugging the male head is a plug-in end, and a plug-in cavity for plugging the male head is provided; a positioning hole is provided on the inner wall of the plug-in cavity, and the positioning hole is provided at the position where the female head corresponds to the first clamping position and the second clamping position of the male head, so that after the male head is connected to the female head, the first buckle and the second buckle can be connected in the positioning hole; an unlocking block equal to the number of the mounting grooves is slidably connected to the outer wall of the female head, and the unlocking block can be moved to the positioning hole corresponding to the first clamping position and the second clamping position along the plug-in direction of the male head and the female head.

[0007] The effect is that when the male head and the female head are plugged in, the first buckle and the second buckle in the positioning buckle each correspond to a positioning hole, the positioning hole is opened on the female head, and the positioning buckle is fixed on the male head. When the first buckle and the second buckle are both in the positioning hole and are engaged, the first buckle and the second buckle can relatively fix the positions of the male head and the female head, thereby preventing the male head and the female head from being disengaged. When professional personnel need to perform maintenance, they first move multiple different unlocking blocks toward the first buckle or the second buckle, each of the first buckle and the second buckle corresponds to an unlocking block, and the number of unlocking blocks is the same as the number of the first buckle and the second buckle, that is, the position and number of the first buckle in the first engaging position and the position and number of the second buckle in the second engaging position will not be normally unlocked due to simple attempts by non-professionals. Only when each of the first buckle and the second buckle is correctly abutted against the corresponding unlocking block can they be unlocked, which can improve safety and make it more convenient for professionals to disassemble.

[0008] Preferably, a sliding cavity is provided inside the female head, and the female head forms an outer layer and an inner layer through the sliding cavity, the positioning hole is opened on the inner layer, the unlocking block is slidably connected to the outer layer, the unlocking block extends into the sliding cavity, and the outer layer is used to hide the positioning hole on the inner layer.

[0009] The effect is that the unlocking block is slidably connected to the outer layer, and a positioning hole is provided on the inner layer, so that the outer layer covers the position of the positioning hole, thereby facilitating the hiding of the positioning hole and the first buckle and the second buckle.

[0010] Preferably, an elastic member and a reset member are provided in the sliding cavity, the elastic member is connected to the reset member, the reset member is slidably connected in the sliding cavity, and the reset member moves along the sliding cavity toward the plug-in end of the female head under the action of the elastic member; the length of the reset member is equal to the length of the sliding cavity perpendicular to the plug-in direction of the male head and the female head.

[0011] The effect is that when the female head and the male head are disassembled, the reset member is automatically moved toward the unlocking block by the elastic member, so that the unlocking block at the first locking position automatically moves toward the positioning hole at the plug-in end. At this time, the unlocking block can prevent the positioning hole from being engaged with the first clip again during the disassembly process of the female head, so that it can be directly pulled out, which is convenient for disassembly.

[0012] Preferably, a card slot is provided on the outer layer of the female head, and the card slot is connected to the sliding cavity. The card slot extends from the plug-in end of the female head parallel to the plug-in direction of the male head and the female head, and the card slot extends away from the plug-in end at an end beyond the sliding position of the unlocking block. A push rod for inserting into the card slot is fixedly provided on the side wall of the male head; one end of the push rod is used to abut against the reset member, and after the male head and the female head are plugged together, the push rod is used to maintain the reset member in a position outside the two positioning holes.

[0013] The effect is that during the process of plugging the female head and the male head together, the push rod abuts against the reset member to keep the reset member in position; when the plugging of the female head and the male head is completed, the reset member is located outside the two positioning holes, thereby avoiding the reset member from blocking the moving position of the unlocking block.

[0014] Preferably, the male connector is provided with a conductive member 1 for connecting the wiring harness, the female connector is provided with a conductive member 2 for connecting the wiring harness, the distance from one end of the conductive member 2 located in the plug-in cavity to the plug-in end is a, the distance from the first clamping position to the end of the male connector is b, the distance from the second clamping position to the end of the male connector is c, and b <a<c。

[0015] The effect is that when the male head and the female head are connected to each other, when the length of the male head inserted into the female head is the distance from the first clamping position to the end of the male head, the conductive member 1 and the conductive member 2 are not normally connected at this time, until the length of the male head inserted into the female head reaches the distance from one end of the conductive member 2 located in the plug-in cavity to the plug-in end, the conductive member 1 and the conductive member 2 are electrically connected to each other. However, at this time, the elastic member has exerted a force on the push rod. If it is not correctly plugged into place, the force of the elastic member will automatically bounce the male head and the female head apart to separate the conductive member 1 and the conductive member 2, thereby avoiding automatic disengagement during use due to false connection.

[0016] At the same time, due to the mutual abutment between the push rod and the reset member, a separating force is generated between the male head and the female head, and the mutual clamping force generated by the first buckle and the second buckle needs to be balanced, so that the male head and the female head will not slide due to minor vibrations after being connected, thereby improving the service life of the internal conductive parts 1 and 2.

[0017] Preferably, the cross-sections of the male and female connectors are circular, square or rectangular.

[0018] The effect is that the shapes of the male and female connectors can be set according to different wiring harnesses to improve applicability.

[0019] Preferably, the shapes of the male and female heads are uniformly set, the structures of the first buckle and the second buckle are the same, the first buckle and the second buckle are assembled with the male head, and the male head is provided with grouping information for identifying the arrangement positions of the first buckle and the second buckle, and the first buckle or the second buckle is fixed in the corresponding installation groove through the grouping information.

[0020] The effect is that the first buckle and the second buckle are assembled post-assembled to make the male and female heads have the same shape, making the batch production process of the male and female heads more convenient. At the same time, the positions for installing the first buckle and the second buckle can be easily determined through the grouping information.

[0021] Preferably, the first buckle includes an elastic sheet and a positioning column, the positioning column is fixed at one end of the elastic sheet, the elastic sheet has a hole at one end away from the positioning column, a fixing column is provided at the bottom of the mounting groove, the elastic sheet is sleeved on the fixing column and fixed, the positioning column extends from the mounting groove through the elastic sheet, and the end of the positioning column away from the elastic sheet is set into a hemispherical shape, and the female head is provided with a chamfer on the inner side of the plug-in end.

[0022] The effect is that the first buckle and the second buckle composed of the elastic sheet and the positioning column can make the space occupied by the first buckle and the second buckle smaller, so as to reduce the size of the male head and the female head increased by setting the first buckle and the second buckle.

[0023] Preferably, the sliding cavity is arranged in a ring shape, a blocking ring is arranged on one side of the sliding cavity away from the abutting end, the elastic member is a spring, one end of the elastic member abuts against the blocking ring, and the blocking ring is detachably connected to the female head.

[0024] The effect is that the blocking ring is connected to the female head in a detachable manner, which facilitates the arrangement of the elastic member and the reset member in the sliding cavity.

[0025] Preferably, the sliding cavity is located on a side wall of the female head, the reset member is arranged in a long strip shape, the elastic member is pulled between the reset member and the plug-in end of the female head, and at least two push rods are arranged and respectively abut against the side walls at both ends of the reset member.

[0026] The effect is that the reset member is arranged in a long strip shape, and when the elastic member pulls the reset member, two push rods simultaneously abut against both ends of the reset member, thereby reducing the tilt of the reset member caused by different pulling forces of the elastic member and improving the stability of the reset member.

[0027] By adopting the above technical solution, the beneficial effects of the present invention are as follows: The present invention has the same number of unlocking blocks as the number of the first buckle and the second buckle. The unlocking block must be correctly moved to abut against the first buckle and the second buckle to be normally unlocked, so that non-professionals cannot normally unlock it by simple attempts, which can improve safety and make it more convenient for professionals to disassemble. In addition, in the process of unlocking the male head and the female head, the reset member is automatically moved in the direction of the unlocking block by the action of the elastic member, preventing the first buckle from being engaged with another positioning hole during the disassembly of the female head, so that it can be directly pulled out and convenient for disassembly. In addition, when the male head and the female head are not correctly plugged into place to complete the electrical connection, the action of the elastic member will automatically bounce the male head and the female head apart to separate the conductive member one and the conductive member two, avoiding automatic disengagement during use due to virtual connection, and ensuring the accuracy of plugging.

[0030] The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0031] The following will describe a wire harness connection device of the present invention in conjunction with Figures 1 to 8 Describe a wire harness connection device of the present invention.

[0032] Embodiment 1 This embodiment discloses a wire harness connection device. As shown in Figure 1 and Figure 2 , it includes a male head 1 and a female head 2. One end of the male head 1 and the female head 2 is used to connect the wire harness 3, and the other end is used for mutual plugging. A first conductive member 31 is arranged inside the male head 1, and a second conductive member 32 is arranged inside the female head 2. The first conductive member 31 and the second conductive member 32 can be provided in multiple numbers according to the number of wires in the wire harness 3. Both the first conductive member 31 and the second conductive member 32 are electrically connected to the wires in the wire harness 3, and the first conductive member 31 and the second conductive member 32 are also plugged into each other, and the plugging direction of the first conductive member 31 and the second conductive member 32 is the same as the plugging direction of the male head 1 and the female head 2. That is, when the male head 1 is plugged into the female head 2, the first conductive member 31 and the second conductive member 32 complete the plugging.

[0033] Referring to Figure 2 and Figure 3 , the male head 1 can be set to a cylindrical shape according to the specifications of the wire harness 3. In this embodiment, the cross-section can also be set to a square. A plurality of installation grooves 11 are formed on the peripheral wall of the male head 1. The plurality of installation grooves 11 can be circumferentially and uniformly arranged on the peripheral wall of the male head 1. The installation grooves 11 are arranged in a long strip shape, and the length direction of the installation grooves 11 is parallel to the plugging direction of the male head 1 and the female head 2. A positioning buckle is fixedly arranged on the male head 1. The positioning buckle includes a first buckle 41 and a second buckle 42. At least one of the first buckle 41 and the second buckle 42 is provided, and the total number of the first buckle 41 and the second buckle 42 should be equal to the number of the installation grooves 11. One first buckle 41 or one second buckle 42 is installed in each installation groove 11, and the first buckle 41 and the second buckle 42 will not be in the same installation groove 11 at the same time. The first buckle 41 and the second buckle 42 are respectively located at both ends of the installation groove 11, so that the position of the first buckle 41 is the first clamping position 51, and the position of the second buckle 42 is the second clamping position 52.

[0034] The shape of the female head 2 matches the shape of the male head 1, and one end of the female head 2 for connecting the male head 1 is the plugging end 21. An insertion cavity 22 for connecting the male head 1 is formed at one end of the female head 2 at the plugging end 21. The second conductive member 32 extends into the insertion cavity 22 and the end part is plugged into the first conductive member 31 entering the insertion cavity 22. The distance from the end of the second conductive member 32 located in the insertion cavity 22 to the plugging end 21 is a, the distance from the first clamping position 51 to the end of the male head 1 is b, the distance from the second clamping position 52 to the end of the male head 1 is c, and b < a < c. In this embodiment, a = (b + c) / 2 can be set.

[0035] Referring to Figure 3 and Figure 4, the female head 2 is provided with a positioning hole 23 on the inner wall of the plug-in cavity 22, and the positioning hole 23 is used to connect the first buckle 41 or the second buckle 42. The positioning holes 23 are arranged corresponding to the first clamping position 51 and the second clamping position 52 of the male head 1, so that each installation slot 11 corresponds to two positioning holes 23. An unlocking block 6 is slidably connected to the female head 2, and the unlocking block 6 can squeeze the first buckle 41 or the second buckle 42 when it slides to the position of the two positioning holes 23. The setting position of the unlocking block 6 on the female head 2 corresponds to the installation slot 11 on the male head 1. When the male head 1 needs to be disassembled after being connected to the female head 2, each unlocking block 6 must be moved to the position of the corresponding first buckle 41 and the second buckle 42. The positions and quantities of the multiple first buckles 41 and the second buckles 42 in this embodiment can be grouped and set during the production process, and the grouping information can be arranged at a convenient location on the outside of the male head 1 and the female head 2, or a fixed mode can be adopted, and it does not need to be set on the male head 1 or the female head 2. When professional maintenance personnel disassemble the male head 1 and the female head 2, they can first check the grouping information to obtain the positions where the multiple unlocking blocks 6 need to be moved, so that the multiple unlocking blocks 6 can be correctly moved to the unlocking position of all the first buckles 41 and the second buckles 42, and then the male head 1 and the female head 2 can be disassembled. The grouping information can be set to multiple numbers or multiple color combinations. If non-professionals cannot move all the unlocking blocks 6 to the correct position due to arbitrary sliding of the unlocking blocks 6, at least one positioning hole 23 between the female head 2 and the male head 1 is connected to the first buckle 41 or the second buckle 42, so that the female head 2 and the male head 1 cannot be opened, for example, all the unlocking blocks 6 are corresponding to the position of the second buckle 42, and the first buckle 41 is connected in the positioning hole 23, preventing the male head 1 and the female head 2 from being disassembled.

[0036] Meanwhile, the first buckle 41 and the second buckle 42 in this embodiment have the same structure. During the production process, the first buckle 41 and the second buckle 42 are made separately from the male connector 1 and then assembled. The number and position of the positioning holes 23 in the female connector 2 are the same. Therefore, during the mass production process, the shape of the male connector 1 and the shape of the female connector 2 are uniformly set, and the installation position of the first buckle 41 and the second buckle 42 is determined by the grouping information pasted on the male connector 1, and the grouping information can also be set on the male connector 1 by laser printing.

[0037] The first buckle 41 and the second buckle 42 each include an elastic sheet 411 and a positioning column 412. The elastic sheet 411 and the positioning column 412 can be integrally arranged or fixed by welding. The positioning column 412 is arranged on the surface of one end of the elastic sheet 411, and the other end of the elastic sheet 411 is fixed to the bottom of the mounting groove 11. The end of the elastic sheet 411 provided with the positioning column 412 is tilted toward the opening of the mounting groove 11, so as to facilitate the insertion of one end of the positioning column 412 into the positioning hole 23. The end of the positioning column 412 away from the elastic sheet 411 can be arranged perpendicular to the plugging direction of the male head 1 and the female head 2. The end of the positioning column 412 away from the elastic sheet 411 is provided with a hemispherical shape, so that after the positioning column 412 is squeezed by the unlocking block 6, the hemispherical part of the end of the positioning column 412 enters the positioning hole 23, so that when the male head 1 and the female head 2 move relative to each other, the positioning hole 23 can squeeze the hemispherical part of the positioning column 412. In order to facilitate the installation of the positioning buckle, a fixing column 111 is first formed at the bottom of the installation groove 11 on the male head 1, and a hole is opened at one end of the elastic sheet 411 away from the positioning column 412, so that the elastic sheet 411 is sleeved on the fixing column 111 through the opening, and then the fixing column 111 is heated and squeezed and deformed to fix the elastic sheet 411.

[0038] The inner side of the plug end 21 of the female connector 2 is provided with a chamfer 24, so that when the female connector 2 is connected to the male connector 1, the chamfer 24 squeezes and deforms the first buckle 41, so that the positioning column 412 of the first buckle 41 abuts against the side wall of the plug cavity 22. Figure 5 , a sliding cavity 25 is also provided inside the female head 2. The sliding cavity 25 in this embodiment is annular. The sliding cavity 25 divides the female head 2 into an outer layer 26 and an inner layer 27. The positioning hole 23 is provided on the inner layer 27, so that the position of the positioning hole 23 cannot be observed from the outside of the female head 2, so as to hide the first buckle 41 or the second buckle 42 connected in the positioning hole 23. A guide groove 28 is provided on the outer layer 26, and the length direction of the guide groove 28 is parallel to the plug-in direction of the male head 1 and the female head 2. The unlocking block 6 is slidably connected in the guide groove 28. When the unlocking block 6 slides to the two ends of the guide groove 28, the part of the unlocking block 6 located in the sliding cavity 25 can cover the positioning hole 23. A part of the unlocking block 6 is located in the sliding cavity 25, and the other part extends from the position of the guide groove 28 to the outside of the outer layer 26, so that the staff can move the unlocking block 6 conveniently.

[0039] An elastic member 71 is disposed in the sliding cavity 25. The elastic member 71 can be configured as a spring. The elastic member 71 is sleeved on the outer side of the inner layer 27. A blocking ring 72 is disposed at one end of the elastic member 71. The blocking ring 72 is fixed to the female head 2 by a threaded connection. The blocking ring 72 blocks the end of the sliding cavity 25 away from the plug-in end 21, so that the elastic member 71 can be installed in the sliding cavity 25 after the blocking ring 72 is removed. A reset member 73 is disposed at one end of the elastic member 71 away from the blocking ring 72. The reset member 73 is configured as a ring. The reset member 73 is sleeved on the outer side of the inner layer 27 and slides in the sliding cavity 25. The force of the elastic member 71 pushes the reset member 73 to move toward the unlocking block 6, thereby moving the unlocking block 6 to the end of the guide groove 28 close to the plug-in end 21.

[0040] A slot 8 is also provided on the outer layer 26 of the female connector 2. The slot 8 is connected to the sliding cavity 25. The slot 8 extends from the plug-in end 21 of the female connector 2 and is parallel to the guide slot 28. The end of the slot 8 away from the plug-in end 21 is at least beyond the position where the unlocking block 6 can be away from the plug-in end 21. A push rod 9 is provided on the side wall of the male connector 1 to cooperate with the slot 8. One end of the push rod 9 is inserted into the slot 8 and is used to abut against the reset member 73. When the female connector 2 is connected to the male connector 1, the end of the push rod 9 abuts against the reset member 73, so that the reset member 73 squeezes the elastic member 71 to deform and shrink, so as to keep the reset member 73 in the position between the two positioning holes 23, so as to prevent the reset member 73 from affecting the movement of the unlocking block 6.

[0041] The plugging process of male connector 1 and female connector 2: First, the elastic member 71 in the female head 2 moves the multiple unlocking blocks 6 to the positioning hole 23 close to the plug-in end 21, and then the female head 2 is sleeved onto the male head 1, and the chamfer 24 on the female head 2 first squeezes and contracts the first buckle 41, so that the female head 2 can be smoothly connected to the male head 1; when the positioning hole 23 on the female head 2 close to the plug-in end 21 is at the position of the first buckle 41, although the first buckle 41 can enter the positioning hole 23, due to the limitation of the unlocking block 6, the end of the positioning column 412 of the first buckle 41 is located in the positioning hole 23, so the female head 2 can continue to be moved, and at this time the push rod 9 abuts against the reset member 73, and the unlocking block 6 at least Half of it passes through the first clamping position 51, so that the reset member 73 squeezes the elastic member 71 to deform, and then the female head 2 is put on the male head 1, and the unlocking block 6 passes through the first clamping position 51. At this time, the conductive member 1 31 and the conductive member 2 32 begin to be plugged in. If the female head 2 is not moved further due to misjudgment at this time, so that the female head 2 is accurately connected in place, the force generated by the elastic member 71 on the push rod 9 will separate the male head 1 and the female head 2, thereby separating the conductive member 1 31 and the conductive member 2 32, so as to avoid the situation where the male head 1 and the female head 2 are not correctly clamped, and the conductive member 1 31 and the conductive member 2 32 are already electrically connected, and the staff cannot find the problem of incorrect connection in time. If the conductive member 1 31 and the conductive member 2 32 are automatically separated, because they cannot conduct electricity normally, the staff can find the problem in time to avoid disconnection due to incorrect connection during use. When the female connector 2 is further moved onto the male connector 1, the positioning hole 23 on the female connector 2 close to the plug-in end 21 reaches the second locking position 52, and the positioning hole 23 on the female connector 2 away from the plug-in end 21 reaches the first locking position 51, so that the first buckle 41 and the second buckle 42 are simultaneously connected to the corresponding positioning holes 23, and the unlocking block 6 is blocked by the second buckle 42 and is located between the two positioning holes 23.

[0042] Disassembly process of male connector 1 and female connector 2: According to the position of the unlocking block 6 located on the grouping information, the unlocking block 6 is moved. The grouping information can be a grouping of 1 and 2, 1 represents that the unlocking block 6 is in the first clamping position 51, and 2 represents that the unlocking block 6 is in the second clamping position 52. When all the unlocking blocks 6 are moved to the correct position, the unlocking block 6 presses the first buckle 41 and the second buckle 42 into the positioning hole 23. At this time, the force of the elastic member 71 keeps the reset member 73 abutting against the push rod 9, so that the male head 1 and the female head 2 have a tendency to separate from each other, so that the male head 1 and the female head 2 are automatically moved in the direction of disengagement under the action of the elastic member 71. When the female connector 2 moves in the direction of disengaging from the male connector 1, the reset member 73 squeezes the unlocking block 6 located at the first engaging position 51 and automatically moves to the positioning hole 23 close to the plug-in end 21. At the same time, when the positioning hole 23 close to the plug-in end 21 on the female connector 2 reaches the first engaging position 51, the first buckle 41 of the first engaging position 51 will be inserted into the positioning hole 23 again. At this time, the unlocking block 6 automatically moved to the plug-in end 21 can be blocked in the positioning hole 23, so that the female connector 2 can continue to move, and even the female connector 2 and the male connector 1 can be completely separated automatically under the action of inertia force, thereby facilitating disassembly.

[0043] Embodiment 2 This embodiment discloses a wiring harness connection device, such as Figure 6 and Figure 7 As shown, the difference from the first embodiment is that the male connector 1 and the female connector 2 adopt a flat rectangular structure according to the arrangement of the wiring harness 3, a plurality of mounting grooves 11 are opened on a side surface of the male connector 1 and the arrangement direction of the plurality of mounting grooves 11 is perpendicular to the plug-in direction of the male connector 1 and the female connector 2.

[0044] refer to Figure 7 and Figure 8 The outer layer 26 of the female connector 2 is only arranged outside the inner layer 27 corresponding to the mounting groove 11, so that the sliding cavity 25 is only located in one side wall of the female connector 2.
