Description

Technical Field

[0001] The present invention relates to the technical field of wire harness connection, and particularly relates 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 of the wire harness. Common connection methods used by operators include connection with a terminal block and connection by winding with tape. There are various types of terminal blocks, such as a spring terminal block, a bolt-type terminal block, and a push-type terminal block. The connection between wire harnesses usually involves the simultaneous connection of multiple wires and is commonly used in automobiles, household appliances, electronic instruments, etc. When the connection between wire harnesses is in a long-term vibration environment, in order to prevent the wire harness from falling off, an anti-detachment structure needs to be set for the wire harness connection device, such as the wire harness in an automobile.

[0003] The Chinese patent document with the authorization announcement number CN108336544B discloses a wire harness connector, which includes a first base, a first pressing plate, a first conductive joint, a second base, a second pressing plate, and a second conductive joint. The first base and the second base are used to connect wire harnesses. The first pressing plate is used to press the wire harness in the first base, and the second pressing plate is used to press the wire harness in the second base. The first conductive joint is electrically connected to the wire harness in the first base, and the second conductive joint is electrically connected to the wire 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-detachment structure for fixing the rear openings of the first base and the second base.

[0004] However, the anti-detachment structure formed by the cooperation of the buckle and the card hole is likely to fall off during vibration. At the same time, it is very easy for non-professionals to press the buckle, causing the buckle to come out of the card hole, resulting in misoperation. If it is not installed in place, it can still conduct electricity, but it is very insecure and is likely to cause loosening or accidental disconnection. In order to reduce misoperation by non-professionals, it is usually necessary to increase the strength of the buckle so that the buckle is difficult to press. However, such a setting also requires a tool to pry when professionals perform maintenance, making disassembly very inconvenient. Summary of the Invention

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

[0006] A wire harness connection device of the present invention includes a male head and a female head that mates with the male head. A positioning buckle for clamping the female head is fixedly arranged on the male head. The positioning buckle includes a first buckle and a second buckle. A plurality of mounting grooves for mounting the first buckle or the second buckle are formed on the male head. Each mounting groove correspondingly mounts a first buckle or a second buckle. The position where the first buckle is mounted is the first clamping position, and the position where the second buckle is mounted is the second clamping position. One end of the female head for plugging into the male head is a plugging end, and a plugging cavity for plugging the male head is formed. Positioning holes are formed on the inner wall of the plugging cavity. The positioning holes are provided at positions corresponding to the first clamping position and the second clamping position of the male head on the female head, so that after the male head and the female head are connected, both the first buckle and the second buckle can be connected in the positioning holes. A plurality of unlocking blocks equal in number to the mounting grooves are slidably connected to the outer wall of the female head. The unlocking blocks can move along the plugging direction of the male head and the female head to the positioning holes corresponding to the first clamping position and the second clamping position.

[0007] The effect is as follows: When the male head and the female head are plugged together, each of the first buckle and the second buckle in the positioning buckle corresponds to a positioning hole. The positioning holes are formed on the female head, and the positioning buckle is fixed on the male head. When both the first buckle and the second buckle are clamped in the positioning holes, 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 coming apart. When professional personnel need to perform maintenance, first move a plurality of different unlocking blocks towards 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 at the first clamping position and the position and number of the second buckle at the second clamping position will not be normally unlocked due to simple attempts by non-professional personnel. Only when each of the first buckle and the second buckle correctly abuts against the corresponding unlocking block can it be unlocked, which can improve safety and also make it convenient for professional personnel to disassemble.

[0008] Preferably, a sliding cavity is arranged inside the female head. The female head forms an outer layer and an inner layer through the sliding cavity. The positioning holes are formed on the inner layer, the unlocking blocks are slidably connected to the outer layer, and the unlocking blocks extend into the sliding cavity. The outer layer is used to hide the positioning holes on the inner layer.

[0009] The effect is as follows: The unlocking blocks are slidably connected to the outer layer, and the positioning holes are formed on the inner layer, so that the outer layer covers the positions of the positioning holes, which is convenient for hiding the positioning holes from the first buckle and the second buckle.

[0010] Preferably, an elastic member and a reset member are arranged in the sliding cavity. The elastic member is connected to the reset member. The reset member is slidably connected in the sliding cavity and moves along the sliding cavity towards the plugging 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 plugging 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 in the direction of the unlocking block under the action of the elastic member, so that the unlocking block at the first latching position automatically moves towards the positioning hole at the insertion end. At this time, when the female head is being disassembled, the unlocking block can prevent the positioning hole from being latched with the first buckle again, so that it can be directly pulled out, facilitating disassembly.

[0012] Preferably, a slot is provided on the outer layer of the female head, and the slot communicates with the sliding cavity. The slot extends parallel to the insertion direction of the male head and the female head starting from the insertion end of the female head, and the extending position of the end of the slot far from the insertion end exceeds the sliding position of the unlocking block. A push rod for inserting into the 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. After the male head and the female head are inserted, the push rod is used to maintain the reset member at a position outside the two positioning holes.

[0013] The effect is that during the insertion process of the male head and the female head, the push rod abuts against the reset member to keep the reset member in position. When the male head and the female head are inserted, the reset member is at a position outside the two positioning holes, thus avoiding the blocking of the movement position of the unlocking block by the reset member.

[0014] Preferably, a first conductive member for connecting a wire harness is provided in the male head, and a second conductive member for connecting a wire harness is provided in the female head. The distance from the end of the second conductive member located in the insertion cavity to the insertion end is a, the distance from the first latching position to the end of the male head is b, and the distance from the second latching position to the end of the male head is c, and b < a < c.

[0015] The effect is that during the connection process of the male head and the female head, when the length of the male head inserted into the female head is the distance from the first latching position to the end of the male head, the first conductive member and the second conductive member are not normally connected yet. It is not until the length of the male head inserted into the female head reaches the distance from the end of the second conductive member located in the insertion cavity to the insertion end that the first conductive member and the second conductive member are electrically connected to each other. However, at this time, the elastic member has exerted a force on the push rod. If the insertion is not in place correctly, the force of the elastic member will automatically push the male head and the female head apart, so that the first conductive member and the second conductive member are separated, avoiding false connection and automatic disconnection during use.

[0016] At the same time, due to the mutual abutment between the push rod and the reset member between the male head and the female head, a separating force is generated, and a mutual latching force needs to be generated between the first buckle and the second buckle for balance, so that the male head and the female head will not slide due to small vibrations after being connected, improving the service life of the first conductive member and the second conductive member inside.

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

[0018] The effect is that the shapes of the male head and the female head can be set according to different wire harnesses, improving the applicability.

[0019] Preferably, the shapes of the male head and the female head 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 later, making the shapes of the male head and the female head unified, facilitating the mass production process of the male head and the female head, and 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 piece and a positioning post. The positioning post is fixed at one end of the elastic piece. An opening is provided at the end of the elastic piece away from the positioning post. A fixing post is provided at the bottom of the installation groove. The elastic piece is sleeved on the fixing post and fixed. The positioning post extends out of the installation groove through the elastic piece, and the end of the positioning post away from the elastic piece is set to be hemispherical. A chamfer is provided on the inner side of the insertion end of the female head.

[0022] The effect is that the first buckle and the second buckle composed of the elastic piece and the positioning post 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 due to the setting of the first buckle and the second buckle.

[0023] Preferably, the sliding cavity is set to be annular. A blocking ring is provided 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 detachably connected to the female head, facilitating the setting of the elastic member and the reset member in the sliding cavity.

[0025] Preferably, the sliding cavity is on one side wall of the female head. The reset member is set to be long strip-shaped. The elastic member is connected between the reset member and the insertion end of the female head in a pulling manner. At least two push rods are provided and respectively abut against the side walls at both ends of the reset member.

[0026] The effect is that the reset member is set to be long strip-shaped. When the elastic member pulls the reset member, the two push rods simultaneously abut against both ends of the reset member to reduce the inclination of the reset member caused by different pulling forces of the elastic member and improve the stability of the reset member.

[0027] Adopting the above technical solutions, the beneficial effects of the present invention are:

[0028] In the present invention, the number of unlocking blocks is the same as that of the first buckle and the second buckle. The unlocking blocks must be correctly moved to abut against the first buckle and the second buckle to be normally unlocked. Therefore, non-professionals cannot unlock it normally by simple attempts, which can improve safety and also make it convenient for professionals to disassemble. In addition, during the process of unlocking the male head and the female head, the reset member is automatically moved towards the unlocking block under the action of the elastic member, preventing the first buckle from engaging with another positioning hole again during the disassembly of the female head, so that it can be directly pulled out, facilitating disassembly. Moreover, when the first conductive member and the second conductive member are electrically connected before the male head and the female head are correctly plugged in place, the acting force of the elastic member will automatically push the male head and the female head apart to separate the first conductive member and the second conductive member, avoiding virtual connection and automatic disconnection during use, and ensuring the accuracy of the plug-in.

Specific Embodiments

[0039] The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0040] The following combines Figures 1 to 8 to describe a wire harness connection device of the present invention.

[0041] Embodiment 1

[0042] 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 are plugged.

[0043] 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 provided on the circumferential wall of the male head 1. The plurality of installation grooves 11 can be circumferentially and uniformly arranged on the circumferential 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.

[0044] The shape of the female head 2 matches the shape of the male head 1, and the end of the female head 2 for connecting the male head 1 is the insertion end 21. An insertion cavity 22 for connecting the male head 1 is provided at one end of the female head 2 at the insertion end 21. The second conductive member 32 extends into the insertion cavity 22 and its end is inserted into the first conductive member 31 that enters the insertion cavity 22. The distance from the end of the second conductive member 32 located in the insertion cavity 22 to the insertion end 21 is a, the distance from the first clamping position 51 to the end of the male head 1 is b, and 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.

[0045] Reference Figure 3 and Figure 4 , on the inner wall of the insertion cavity 22 of the female head 2, positioning holes 23 are provided, and the first clamping buckle 41 or the second clamping buckle 42 is used for connection in the positioning holes 23. The positioning holes 23 are provided corresponding to both the first clamping position 51 and the second clamping position 52 of the male head 1, so that each installation groove 11 corresponds to two positioning holes 23. An unlocking block 6 is slidably connected to the female head 2. When the unlocking block 6 slides to the positions of the two positioning holes 23, it can squeeze the first clamping buckle 41 or the second clamping buckle 42. The setting positions of the unlocking block 6 on the female head 2 correspond one-to-one with the installation grooves 11 on the male head 1. When it is necessary to disassemble the male head 1 and the female head 2 after connection, each unlocking block 6 must be moved to the positions corresponding to the first clamping buckle 41 and the second clamping buckle 42. In this embodiment, the positions and quantities of the multiple first clamping buckles 41 and the second clamping buckles 42 can be grouped and set during the production process. The grouping information can be arranged at a convenient viewing position on the outer sides of the male head 1 and the female head 2, or can adopt a fixed mode and 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 view the grouping information to obtain the positions where the multiple unlocking blocks 6 need to be moved, so that the multiple unlocking blocks 6 are correctly moved to the positions for unlocking all the first clamping buckles 41 and the second clamping buckles 42, and then the male head 1 and the female head 2 can be disassembled. The grouping information can be set as multiple numbers or a combination of multiple colors. For any random sliding of the unlocking block 6 by non-professionals, if all the unlocking blocks 6 cannot be moved to the accurate positions, at least one of the positioning holes 23 between the female head 2 and the male head 1 is connected with the first clamping buckle 41 or the second clamping buckle 42, preventing the female head 2 and the male head 1 from being opened. For example, when all the unlocking blocks 6 correspond to the positions of the second clamping buckles 42, the first clamping buckles 41 are connected in the positioning holes 23, preventing the disassembly of the male head 1 and the female head 2.

[0046] 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 separately manufactured from the male head 1 and then assembled. The number and positions of the positioning holes 23 in the female head 2 are the same. Therefore, during mass production, the shapes of the male head 1 and the female head 2 are uniformly set, and the installation positions of the first buckle 41 and the second buckle 42 are determined by the grouping information pasted on the male head 1. The grouping information can also be set on the male head 1 by laser printing.

[0047] Both the first buckle 41 and the second buckle 42 include an elastic piece 411 and a positioning post 412. The elastic piece 411 and the positioning post 412 can be integrally provided or fixed by welding. The positioning post 412 is arranged on the surface at one end of the elastic piece 411. The other end of the elastic piece 411 is fixed to the bottom of the installation groove 11. One end of the elastic piece 411 where the positioning post 412 is arranged tilts towards the opening of the installation groove 11, facilitating the insertion of one end of the positioning post 412 into the positioning hole 23. One end of the positioning post 412 away from the elastic piece 411 can be arranged perpendicular to the insertion direction of the male head 1 and the female head 2. A hemispherical shape is provided at one end of the positioning post 412 away from the elastic piece 411. After the positioning post 412 is squeezed by the unlocking block 6, the hemispherical part at the end of the positioning post 412 enters the positioning hole 23. 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 post 412. To facilitate the installation of the positioning buckle, a fixing post 111 is first formed at the bottom of the installation groove 11 on the male head 1. An opening is made at the other end of the elastic piece 411 away from the positioning post 412, enabling the elastic piece 411 to be sleeved on the fixing post 111 through the opening. Then, the fixing post 111 is heated and squeezed to deform to fix the elastic piece 411.

[0048] A chamfer 24 is provided inside the insertion end 21 of the female head 2. When the female head 2 is connected to the male head 1, the chamfer 24 squeezes the first buckle 41 to deform, causing the positioning post 412 of the first buckle 41 to abut against the side wall of the insertion cavity 22. Figure 5 Furthermore, a sliding cavity 25 is 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 arranged on the inner layer 27, making the position of the positioning hole 23 invisible from the outside of the female head 2 to hide the first buckle 41 or the second buckle 42 connected in the positioning hole 23. A guiding groove 28 is provided on the outer layer 26. The length direction of the guiding groove 28 is parallel to the insertion direction of the male head 1 and the female head 2. The unlocking block 6 is slidably connected in the guiding groove 28. When the unlocking block 6 slides to both ends of the guiding groove 28, the part of the unlocking block 6 located inside the sliding cavity 25 can block the positioning hole 23. A part of the unlocking block 6 is located inside the sliding cavity 25, and the other part extends from the position of the guiding groove 28 to the outside of the outer layer 26, facilitating the staff to move the unlocking block 6.

[0049] An elastic member 71 is disposed within the sliding cavity 25. The elastic member 71 can be configured as a spring. The elastic member 71 is sleeved outside the inner layer 27. A blocking ring 72 is provided at one end of the elastic member 71. The blocking ring 72 is fixed to the female head 2 by means of a threaded connection. And the blocking ring 72 blocks one end of the sliding cavity 25 away from the insertion end 21, so that the elastic member 71 can be installed in the sliding cavity 25 after the blocking ring 72 is disassembled. A reset member 73 is provided at the 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 outside the inner layer 27 and slides within the sliding cavity 25. The acting force of the elastic member 71 pushes the reset member 73 towards the unlocking block 6, thereby moving the unlocking block 6 to one end of the guiding groove 28 close to the insertion end 21.

[0050] A card slot 8 is further formed on the outer layer 26 of the female head 2. The card slot 8 communicates with the sliding cavity 25. The card slot 8 extends from the insertion end 21 of the female head 2 and is parallel to the guiding groove 28. The end of the card slot 8 away from the insertion end 21 at least exceeds the position where the unlocking block 6 can move away from the insertion end 21. A push rod 9 cooperating with the card slot 8 is provided on the side wall of the male head 1. One end of the push rod 9 is inserted into the card slot 8 and is used to abut against the reset member 73. When the female head 2 is connected to the male head 1, the end of the push rod 9 abuts against the reset member 73, causing the reset member 73 to squeeze the elastic member 71 to deform and contract, 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.

[0051] The insertion process of the male head 1 and the female head 2:

[0052] First, the elastic member 71 in the female connector 2 moves multiple unlocking blocks 6 to the positioning holes 23 near the insertion end 21. Then, the female connector 2 is sleeved onto the male connector 1. The chamfer 24 on the female connector 2 first squeezes and contracts the first buckle 41, enabling the female connector 2 to be smoothly connected to the male connector 1. When the positioning hole 23 near the insertion end 21 on the female connector 2 reaches the position of the first buckle 41, although the first buckle 41 can enter the positioning hole 23, due to the restriction of the unlocking block 6, the end of the positioning post 412 of the first buckle 41 is located within the positioning hole 23. Therefore, the female connector 2 can continue to move. At this time, the push rod 9 abuts against the reset member 73, and at least half of the unlocking block 6 passes through the first clamping position 51, causing the reset member 73 to squeeze the elastic member 71 to deform. Then, when the female connector 2 is further sleeved onto the male connector 1, the unlocking block 6 completely passes through the first clamping position 51. At this time, the first conductive member 31 and the second conductive member 32 start to be inserted. If the female connector 2 is not moved further due to misjudgment and the female connector 2 is accurately connected in place, the force generated by the elastic member 71 on the push rod 9 will separate the male connector 1 and the female connector 2, thereby separating the first conductive member 31 and the second conductive member 32, avoiding the situation where the first conductive member 31 and the second conductive member 32 are electrically connected when the male connector 1 and the female connector 2 are not correctly clamped, and the staff cannot timely discover the incorrect connection problem. If the first conductive member 31 and the second conductive member 32 are automatically separated, since they cannot conduct electricity normally, the staff can timely discover the problem 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 near the insertion end 21 on the female connector 2 reaches the second clamping position 52, and the positioning hole 23 far from the insertion end 21 on the female connector 2 reaches the first clamping position 51, causing the first buckle 41 and the second buckle 42 to be simultaneously connected to the corresponding positioning holes 23, and the unlocking block 6 is blocked by the second buckle 42 and is in the position between the two positioning holes 23.

[0053] The disassembly process of the male connector 1 and the female connector 2:

[0054] 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 the 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 positions, the unlocking block 6 presses both the first buckle 41 and the second buckle 42 into the positioning hole 23. At this time, the acting force of the elastic member 71 maintains the abutment of the reset member 73 against the push rod 9, so that the male head 1 and the female head 2 have a tendency to separate from each other. Thus, under the action of the elastic member 71, the male head 1 and the female head 2 are automatically moved in the separating direction. When the female head 2 moves in the direction of separating from the male head 1, the reset member 73 presses the unlocking block 6 located in the first clamping position 51 to automatically move towards the positioning hole 23 near the insertion end 21. At the same time, when the positioning hole 23 near the insertion end 21 on the female head 2 reaches the first clamping position 51, the first buckle 41 in the first clamping position 51 will be inserted into the positioning hole 23 again. At this time, since the unlocking block 6 that has automatically moved to the insertion end 21 just can block in the positioning hole 23, the female head 2 can continue to move, and even under the action of inertia force, the female head 2 and the male head 1 can be completely separated automatically, thus facilitating disassembly.

[0055] Embodiment 2

[0056] This embodiment discloses a wire harness connection device, as Figure 6 and Figure 7 shown. The difference from Embodiment 1 is that the male head 1 and the female head 2 adopt a flat rectangular structure according to the layout form of the wire harness 3.
