Description

Technical Field

[0001] The present invention relates to the field of automotive wiring harnesses, and more particularly to an automotive wiring harness connector. Background Art

[0002] Automotive wiring harness connectors are usually used to connect two wiring harnesses to achieve the purpose of connecting electrical signals or turning on the power supply. Most existing automotive wiring harness connectors consist of a male plug and a female plug. The male plug and the female plug are docked and fixed by a buckle. Since the buckle is made of plastic with a certain elasticity, the buckle may sometimes break under multiple plugging and unplugging operations, resulting in loosening at the connection between the male plug and the female plug. Especially during the driving of the vehicle, if the connection becomes loose, it will affect the normal operation of automotive electronic devices, leading to vehicle failures and posing significant safety hazards.

[0003] In addition, the terminals of the male plug and the female plug sometimes get damaged. It is rather troublesome to replace the terminals in existing connectors, and some even require replacing the entire connector, causing unnecessary waste. Summary of the Invention

[0004] The purpose of the present invention is to provide an automotive wiring harness connector to solve the problems mentioned in the above background art.

[0005] An automotive wiring harness connector includes a main housing, a left male plug assembly, and a connection component. The main housing has a housing structure with openings at the upper end and both left and right ends. A limiting protrusion is provided on the right side of the main housing, which divides the internal space of the main housing into a sliding groove on the left side and an installation groove on the right side. A right male plug is installed in the installation groove, and the right male plug is connected to a group of wiring harnesses.

[0006] The left male plug assembly is detachably connected to the opening at the left end of the main housing and can close the opening at the left end of the main housing. The left male plug assembly is connected to another group of wiring harnesses.

[0007] The connection component is slidably connected to the main housing and is used to connect the left male plug assembly and the right male plug, thereby connecting the two groups of wiring harnesses.

[0008] Reset components are provided on both sides of the main housing. When not under external force, the reset components can make the connection component be at the rightmost end, thereby closing the upper opening of the main housing and restricting the right male plug in the installation groove.

[0009] Preferably, two connection columns are further provided on the left side wall of the main housing. Chute and limiting grooves are provided on both sides of the main housing, and the connection columns are located in the limiting grooves.

[0010] Preferably, the male left plug component includes a fixing plate and a baffle. A number of countersunk holes one are provided on the fixing plate, and male left plug terminals are installed in the countersunk holes one. The shoulder one of the male left plug terminal is located in the countersunk hole one. The baffle is arranged on the right side of the fixing plate. The right end of the male left plug terminal passes through the baffle, and the male left plug terminal is slidably connected to the female plug terminal. The fixing plate and the baffle are fixedly connected by screws, connecting columns and guiding columns. Chute are also provided on the fixing plate and the baffle.

[0011] Preferably, the communication component includes a sliding cover and an intermediate connecting block. Limit blocks are provided on both sides of the sliding cover. The limit blocks are slidably connected to the chute. Two clamping blocks are provided at the bottom of the sliding cover. A clamping groove for clamping with the clamping block is provided on the intermediate connecting block. The intermediate connecting block is slidably connected in the sliding groove. A number of female plug terminals are fixedly connected in the intermediate connecting block. Anti-slip patterns are also provided on the top surface of the sliding cover.

[0012] Preferably, the reset component includes a guiding column and a spring. The guiding column is fixedly connected to the main housing. A driving block is further provided at the bottom of the limit block. The driving block is slidably connected to the guiding column. The spring is sleeved on the guiding column between the baffle and the driving block.

[0013] Preferably, countersunk holes two are provided on the male right plug. Male right plug terminals are installed in the countersunk holes two. A shoulder two is provided on the male right plug terminal. The shoulder two is located in the countersunk hole two. A through slot is provided on the side wall of the male right plug. An insertion plate is inserted in the slot. A strip-shaped groove is provided on the insertion plate. The male right plug terminal is located in the strip-shaped groove. The diameter of the shoulder two is smaller than the width of the strip-shaped groove.

[0014] The advantages of the present invention are as follows: Different from the conventional left-right docking connectors, the connection between the male right plug and the main housing in this connector is fixed by installing it into the installation groove from top to bottom and closing the upper end with a sliding cover. This connection method does not require a snap to be clamped, can be opened and closed repeatedly, avoids the loosening and breaking caused by multiple insertions and extractions of the elastic snap, and ensures the stability of the connector.

[0015] While the sliding cover is closed, the intermediate connecting block and the male right plug can be combined, and the female plug terminals and the male right plug terminals can be connected together with the male left plug terminals to achieve a connection effect, realizing the purpose of completing both fixing and docking simultaneously.

[0016] Both the male left plug terminals and the male right plug terminals in this connector adopt a detachable connection method, and the disassembly is convenient, which is convenient for later maintenance and replacement of individual terminals, reducing waste. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting protrusion 11 divides the internal space of the main housing 1 into a sliding groove 12 on the left side and an installation groove 13 on the right side. A right male plug 4 is installed in the installation groove 13, and the right male plug 4 is connected to a group of wiring harnesses.

[0032] The left male plug assembly 2 is detachably connected to the opening at the left end of the main housing 1 and can close the opening at the left end of the main housing 1. The left male plug assembly 2 is connected to another group of wiring harnesses.

[0033] The connection component 3 is slidably connected to the main housing 1 and is used to connect the left male plug assembly 2 and the right male plug 4, thereby connecting the two groups of wiring harnesses.

[0034] Reset components 5 are provided on both sides of the main housing 1. When not under external force, the reset components 5 can make the connection component 3 located at the rightmost end, thereby closing the upper opening of the main housing 1 and restricting the right male plug 4 in the installation groove 13.

[0035] In this embodiment, two connecting columns 14 are further provided on the left side wall of the main housing 1. Sliding grooves 15 and limiting grooves 16 are provided on both sides of the main housing 1, and the connecting columns 14 are located in the limiting grooves 16.

[0036] In this embodiment, the left male plug assembly 2 includes a fixing plate 21 and a baffle 22. A number of countersunk holes 211 are provided on the fixing plate 21. Left male plug terminals 23 are installed in the countersunk holes 211. The shoulder 231 of the left male plug terminal 23 is located in the countersunk hole 211. The baffle 22 is provided on the right side of the fixing plate 21. The right end of the left male plug terminal 23 passes through the baffle 22, thereby fixing the left male plug terminal 23 between the baffle 22 and the fixing plate 21. The left male plug terminal 23 is slidably connected to the female plug terminal 33. The fixing plate 21 and the baffle 22 are fixedly connected to the connecting columns 14 and the guide columns 51 of the main housing 1 by screws. By removing the screws, the fixing plate 21 and the baffle 22 can be removed, and then the fixing plate 21 and the baffle 22 are also provided with sliding grooves 15.

[0037] In this embodiment, the connection component 3 includes a sliding cover 31 and an intermediate connection block 32. Limiting blocks 311 are provided on both sides of the sliding cover 31. The limiting blocks 311 are slidably connected to the sliding grooves 15. Two clamping blocks 312 are provided at the bottom of the sliding cover 31. A clamping groove 321 for clamping the clamping blocks 312 is provided on the intermediate connection block 32. The intermediate connection block 32 is slidably connected to the sliding groove 12. A number of female plug terminals 33 are fixedly connected in the intermediate connection block 32. An anti-slip pattern 313 is further provided on the top surface of the sliding cover 31 to facilitate pushing the sliding cover 31.

[0038] In this embodiment, the reset assembly 5 includes a guide post 51 and a spring 52. The guide post 51 is fixedly connected to the main housing 1. A driving block 314 is further provided at the bottom of the limit block 311. The driving block 314 is slidably connected to the guide post 51. The spring 52 is sleeved on the guide post 51 between the stop block and the driving block 314. The spring 52 can push the sliding cover 31 to the rightmost end to seal the installation groove 13 when the sliding cover 31 is not under external force.

[0039] In this embodiment, a countersunk hole II 41 is provided on the right male plug 4. A right male plug terminal 43 is installed in the countersunk hole II 41. A shoulder is provided on the right male plug terminal 43. The shoulder II 431 is located in the countersunk hole II 41, thereby restricting the rightward movement of the right male plug terminal 43. A through slot 42 is provided on the side wall of the right male plug 4. An insertion plate 44 is inserted into the slot 42. A strip-shaped groove 441 is provided on the insertion plate 44. The right male plug terminal 43 is located in the strip-shaped groove 441. The diameter of the shoulder II 431 is smaller than the width of the strip-shaped groove 441, thereby restricting the leftward movement of the right male plug terminal 43. The strip-shaped groove 441 can block the shoulder on the one hand and enable the insertion plate 44 to be smoothly removed from one side on the other hand.

[0040] Working process and principle:

[0041] When the connector leaves the factory, the left male plug assembly 2 is assembled with the main housing 1, and only the right male plug 4 is used for installation and connection.

[0042] When the right male plug 4 needs to be installed, first push the sliding cover 31 to the left. The sliding cover 31 moves to the left, and the driving block 314 compresses the spring 52. Since the clamping block 312 on the sliding cover 31 is clamped in the slot 321 on the intermediate connecting block 32, the leftward movement of the sliding cover 31 can drive the intermediate connecting block 32 to move to the left together, so that the installation groove 13 is exposed, and the female plug terminal 33 on the intermediate connecting block 32 is moved out of the installation groove 13. Then, the right male plug 4 can be pressed into the installation groove 13 from top to bottom. The limit protrusion 11 and the right side wall of the main housing 1 jointly act to restrict the horizontal freedom of the right male plug 4.

[0043] When the right male plug 4 is placed in the installation groove 13, release the sliding cover 31. The elastic force released by the spring 52 acts on the driving block 314, causing the sliding cover 31 to move to the right and reset. The sliding cover 31 returns to its initial position, that is, the position where the installation groove 13 is completely closed. At this time, the right male plug 4 is completely fixed in the installation groove 13.

[0044] The sliding cover 31 returns to the initial position, driving the intermediate connecting block 32 to move towards the direction of the right male plug 4. The right male plug terminal 43 is inserted into the female plug terminal 33 from the right end of the female plug terminal 33 to achieve connection with the female plug terminal 33. The two female plug terminals 33 slide outside the left male plug terminal 23 and always maintain connection with the left male plug terminal 23. Eventually, the left male plug terminal 23 is connected to the right male plug terminal 43, that is, the two wire harnesses are connected.

[0045] When it is necessary to remove the right male plug 4, push the sliding cover 31 to the left again, and the right male plug 4 can be removed.

[0046] When the left male plug terminal 23 is damaged, only need to remove the screw connecting the fixing plate 21 and the main housing 1, and then take down the baffle 22, then the corresponding left male plug terminal 23 can be replaced. Similarly, when it is necessary to replace the right male plug terminal 43, use a narrow strip tool, such as a flat screwdriver or a needle, to push out the plug board 44, and then replace the corresponding right male plug terminal 43 at the interface, without replacing the entire male plug.

[0047] As is known by common technical knowledge, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the present invention are encompassed by the present invention.
