Description

Technical Field:

[0001] The utility model relates to the technical field of connector products, and particularly to an automotive wire harness connector. Background Art:

[0002] In the automotive manufacturing industry, the connection and installation of automotive wire harnesses are also very important parts. It is not only required that each automotive wire harness is intact before installation, but also that the automotive wire harness can maintain a stable connection state after installation and cannot be easily loosened from each other to cause connection interruption.

[0003] Figures 1-3 As shown, it is an automotive wire harness connector adopted by an automotive wire harness in the prior art, which can realize the use of connectors with 2 pins, 6 pins, and 8 pins to meet different usage requirements.

[0004] Specifically, the automotive wire harness connector includes a first connector 1 and a second connector 2 that can be assembled together for use or can be used separately independently. Among them, the first connector 1 is a 2-pin connector, which has two first terminals 11 and is respectively used to connect with two first wires 12; the second connector 2 is a 6-pin connector, which has six second terminals 21 and is respectively used to connect with six second wires 22. When the first connector 1 and the second connector 2 are used independently, they are used as a 2-pin connector and a 6-pin connector respectively. When the first connector 1 and the second connector 2 are assembled together for use, they are used as an 8-pin connector, so as to meet different usage requirements.

[0005] Among them, the assembly structure of the above-mentioned first connector 1 and second connector 2 is: a dovetail rib 13 in the shape of a dovetail is arranged on the outside of the first connector 1. Correspondingly, a dovetail groove 23 is arranged on the outside of the second connector 2. When the first connector 1 and the second connector 2 are assembled, through the dovetail rib 13 and the dovetail groove 23 being installed by inlaying in the front-back direction (i.e., the length extension direction of the dovetail rib), the first connector 1 and the second connector 2 are firmly assembled together to form a whole as an assembled automotive wire harness connector.

[0006] However, the above-mentioned assembled automotive wire harness connector has some deficiencies: after the dovetail rib 13 of the first connector 1 and the dovetail groove 23 of the second connector 2 are assembled by inlaying, the first connector 1 and the second connector 2 only have a limit in the left-right direction (i.e., the direction perpendicular to the length extension direction of the dovetail rib), but there is no limit in the front-back direction (i.e., the length extension direction of the dovetail rib) between them, that is, there is no anti-withdrawal structure, so there is a risk that the dovetail rib 13 and the dovetail groove 23 can slide relative to each other and come out, resulting in the first connector 1 and the second connector 2 not being fixed in place after being assembled front and back, and the quality of the product cannot be guaranteed.

[0007] In view of this, the inventor has continuously carried out research and development and improvement to propose the following technical solutions. Content of the utility model:

[0016] Furthermore, in the above technical solution, the end of the first elastic clamping arm is also clamped and positioned with the first insulating seat. Among them, a first clamping buckle is also formed on the inner wall of the first window, and a first clamping hole is arranged at the end of the first elastic clamping arm. The first clamping buckle and the first clamping hole are clamped and positioned to position the end of the first elastic clamping arm in the first window and the first terminal hole.

[0017] Furthermore, in the above technical solution, the first elastic clamping arm is J-shaped, and the end of the first elastic clamping arm is bent in an arc shape; there are at least two first terminals, which are symmetrically distributed up and down in the first insulating seat.

[0045] The present utility model will be further described below in conjunction with specific embodiments and the drawings.

[0046] As shown Figures 4-9 in the figure, there is an automotive wire harness connector, which includes a first connector 3 and a second connector 4. A dovetail rib 311 is provided on the outer side of the first connector 3, and a dovetail groove 411 is provided on the outer side of the second connector 4. The first connector 3 and the second connector 4 are assembled together through the cooperation of the dovetail rib 311 and the dovetail groove 411, which is an assembly structure of a conventional automotive wire harness connector. For example Figures 1-3 the assembly structure of the automotive wire harness connector in the prior art shown in the figure.

[0047] In order to ensure that the assembly structure of the automotive wire harness connector is more stable, especially to ensure that the first connector 3 and the second connector 4 can be fixed in place after being assembled front and back, the following design is also made: Combining Figures 7-9 the figure, a first stop block 312 is further provided on the outer side of the first connector 3; a second stop block 412 is further provided on the outer side of the second connector 4. When the first connector 3 and the second connector 4 are assembled front and back, the dovetail rib 311 and the dovetail groove 411 are inlaid and assembled to form a positioning in the left - right direction, and the additionally provided first stop block 312 and the second stop block 412 are mutually engaged and assembled across each other to form an anti - withdrawal structure. Thus, after the first connector 3 and the second connector 4 are assembled front and back, they can be fixed in place, the anti - withdrawal function can be realized, the structure after the assembly of the first connector 3 and the second connector 4 is more stable, the product quality is higher, the risks of dropping and disconnection of the product during transportation can be avoided, and thus the market competitiveness of the present utility model is enhanced.

[0048] Combining Figure 8 the figure, the outer side of the second connector 4 is provided with a first sheet body 403 and a second sheet body 404 that are distributed in a V - shape and protrude outward. A dovetail groove 411 is formed between the first sheet body 403, the second sheet body 404 and the outer side of the second connector 4. The first sheet body 403 and the second sheet body 404 have a certain elastic deformation ability, so that after the dovetail rib 311 and the dovetail groove 411 are inlaid and assembled, the stability between them is higher.

[0049] To further enhance the stability of the first connector 3 and the second connector 4 after being assembled front and back, the following design is also made: Combining Figures 7-8As shown, a stop groove 413 is further provided outside the second connector 4 beside the second stop block 412. The first stop block 312 passes over the second stop block 412 and is embedded in the stop groove 413, and contacts the inner wall 401 on the side of the stop groove 413 away from the second stop block 412 for thrust stopping, that is, it can prevent the first connector 3 and the second connector 4 from being unable to push each other further, achieving the function of thrust stopping. At the same time, the first stop block 312 and the second stop block 412 are clamped and assembled to achieve the function of anti-retreat. Furthermore, after the first connector 3 and the second connector 4 are assembled, they cannot slide relative to each other, thereby ensuring the stability and firmness of the assembly structure of the first connector 3 and the second connector 4, and further improving the quality of the present utility model and the yield rate. Of course, it can also be the reverse design, that is, a stop groove 413 is further provided outside the first connector 3 beside the first stop block 312; the second stop block 412 passes over the first stop block 312 and is embedded in the stop groove 413, and contacts the inner wall 401 on the side of the stop groove 413 away from the first stop block 312 for thrust stopping, which can achieve the same technical effect as the above structure and will not be specifically described herein.

[0050] Among them, in order for the first stop block 312 and the second stop block 412 to better pass over each other, the following design is also made: As shown in Figures 8-9 shown, a first ramp surface 301 is provided on the first stop block 312; a second ramp surface 402 is provided on the second stop block 412. When the first connector 3 and the second connector 4 are assembled front to back, during the process that the first stop block 312 and the second stop block 412 pass over each other, the first ramp surface 301 and the second ramp surface 402 will contact first, which plays a guiding role and enables the first stop block 312 and the second stop block 412 to pass over each other more smoothly, facilitating assembly and making the operation smoother.

[0051] In this embodiment, the distribution relationship among the dovetail groove 411, the stop groove 413 and the second stop block 412 is as follows: As shown in Figure 8 shown, the dovetail groove 411 is divided into two sections, which are distributed at the front and rear ends of the outer side surface of the second connector 4, and a channel 400 communicating the two sections of the dovetail groove 411 and for the dovetail rib 311 to pass through is provided in the middle of the outer side surface of the second connector 4. The stop groove 413 and the second stop block 412 are both provided in the channel 400.

[0052] Correspondingly, as shown in Figure 9 shown, the dovetail rib 311 is divided into two sections, which are distributed at the front and rear ends of the outer side surface of the first connector 3, and the first stop block 312 is provided in the middle of the outer side surface of the first connector 3 and between the two sections of the dovetail rib 311.

[0053] The following describes the specific structure of the first connector 3:

[0054] Combined with Figures 4-6 and Figure 9 As shown, the first connector 3 includes a first insulating base 31 and a plurality of first terminals 32 inserted into the first terminal holes 314 of the first insulating base 31. Each first terminal 32 is fixedly connected to a first wire 34, and the first wire 34 extends out of the first insulating base 31.

[0055] In order to prevent the first terminal 32 from accidentally falling out of the first insulating base 31, the present utility model makes the following design: Combined with Figures 4-6 and Figure 9 As shown, a first window 313 is opened on the surface of the first insulating base 31 from outside to inside, and a first elastic clamping arm 33 is provided on the first insulating base 31. The end of the first elastic clamping arm 33 is pressed into the first window 313 from outside to inside and embedded in the first terminal hole 314, and the end of the first elastic clamping arm 33 abuts against the rear end of the first terminal 32 or is placed behind the rear end of the first terminal 32. Thus, when there is a possibility that the first terminal 32 moves backward, that is, when the first terminal 32 has a phenomenon of falling out of the first insulating base 31, the first terminal 32 will be blocked by the end of the first elastic clamping arm 33, thereby preventing the first terminal 32 from accidentally falling out of the first insulating base 31, improving the yield rate of the product, that is, ensuring the product quality.

[0056] Among them, combined with Figure 6 As shown, the first elastic clamping arm 33 is in a J shape, and the end of the first elastic clamping arm 33 is bent into an arc shape, so that a vertical blocking surface is formed at the end of the first elastic clamping arm 33. The blocking surface abuts against the rear end of the first terminal 32 or is placed behind the rear end of the first terminal 32. The first terminal 32 can be better blocked through the vertical blocking surface, and the first terminal 32 can be more effectively prevented from accidentally falling out of the first insulating base 31.

[0057] In order to enable the first elastic clamping arm 33 to be more stably positioned on the first insulating base 31, and thus better realize the function of preventing the first terminal 32 from accidentally falling out of the first insulating base 31, the following design is also made: Combined with Figure 4 、 6, as shown in Fig. 9, the end of the first elastic clamping arm 33 is also clamped and positioned with the first insulating base 31, thereby ensuring that the end of the first elastic clamping arm 33 can be more stably positioned in the first terminal hole 314, so that the end of the first elastic clamping arm 33 will not accidentally pop out of the first terminal hole 314 and cannot effectively block the first terminal 32. Among them, it should be noted that before the first terminal 32 is inserted into the first terminal hole 314, the end of the first elastic clamping arm 33 pops out under its own elastic force. Preferably, it does not enter the first terminal hole 314, or only a small part of the end of the first elastic clamping arm 33 enters the first terminal hole 314, so as to be more convenient for later inserting the first terminal 32 into the first terminal hole 314, improving the assembly efficiency and ensuring smoother assembly. When the first terminal 32 is inserted into the first terminal hole 314 and assembled in place, then press the first elastic clamping arm 33 from outside to inside, so that the end of the first elastic clamping arm 33 is also clamped and positioned with the first insulating base 31. At this time, the end of the first elastic clamping arm 33 abuts against the rear end of the first terminal 32 or is placed on the rear side of the rear end of the first terminal 32, thereby realizing the function of blocking the first terminal 32 from retreating.

[0058] The specific structure is as follows: a first buckle 315 is also formed on the inner wall of the first window 313, and a first clamping hole 331 is provided at the end of the first elastic clamping arm 33. The first buckle 315 is clamped and positioned with the first clamping hole 331 to position the end of the first elastic clamping arm 33 in the first window 313 and the first terminal hole 314. Its assembly structure is extremely simple and the assembly structure is stable, and the end of the first elastic clamping arm 33 can be stably positioned in the first terminal hole 314, thereby realizing the function of blocking the first terminal 32 from retreating.

[0059] There are at least two first terminals 32, which are symmetrically distributed up and down in the first insulating base 31. Correspondingly, there are at least two first elastic clamping arms 33, which are symmetrically distributed on the upper and lower end faces of the first insulating base 31. That is to say, the first insulating base 31 has the function of preventing the retreat of each first terminal 32, that is, it can ensure that each first terminal 32 will not accidentally withdraw from the first insulating base 31, ensuring the product quality. In this embodiment, the number of the first terminals 32 is two, and the first connector 3 can be considered as a 2-pin connector. Of course, if the number of the first terminals 32 is multiple, the first connector 3 can be considered as a multi-pin connector.

[0060] Combined Figures 4-5 and Figure 8As shown, the second connector 4 includes a second insulating base 41 and a plurality of second terminals 42 inserted into second terminal holes 410 of the second insulating base 41. Each second terminal 42 is connected to a second wire 43. The second wire 43 extends outside the second insulating base 41. The assembly structure of the second insulating base 41 and the second terminals 42 is the same as that of the first insulating base 31 and the first terminals 32, and achieves the same technical effects, which will not be elaborated here one by one.

[0061] For example, a second window 414 is formed on the surface of the second insulating base 41 from outside to inside, and a second elastic clamping arm 44 is provided on the second insulating base 41. The end of the second elastic clamping arm 44 is pressed into the second window 414 from outside to inside and embedded in the second terminal hole 410, and the end of the second elastic clamping arm 44 abuts against the rear end of the second terminal 42 or is placed behind the rear end of the second terminal 42. Thus, when there is a possibility that the second terminal 42 moves backward, that is, when the second terminal 42 has a phenomenon of coming out of the second insulating base 41, the second terminal 42 will be blocked by the end of the second elastic clamping arm 44, thereby preventing the second terminal 42 from accidentally coming out of the second insulating base 41 and improving the yield rate of the product, that is, ensuring the product quality. Among them, a second buckle 415 is formed on the inner wall of the second window 414, and a second card hole 441 is provided at the end of the second elastic clamping arm 44. The second buckle 415 and the second card hole 441 are clamped and positioned.

[0062] In this embodiment, the number of the second terminals 42 is six, and it can be considered that the second connector 4 is a 6-pin connector. Of course, the number of the first terminals 32 is multiple, and it can be considered that the second connector 4 is a multi-pin connector.

[0063] In this embodiment, when the first connector 3 and the second connector 4 are used independently, they are used as 2-Pin connectors and 6-Pin connectors respectively. When the first connector 3 and the second connector 4 are assembled together and used, they are used as 8-Pin connectors, so as to meet different usage requirements.

[0064] In summary, after the first connector 3 and the second connector 4 are assembled front and back, the dovetail ribs 311 and the dovetail grooves 411 are inlaid and assembled to form positioning in the left-right direction, and the additional first stop block 312 and the second stop block 412 are mutually clamped and assembled across each other to form an anti-retreat structure. Thus, after the first connector 3 and the second connector 4 are assembled front and back, they can be fixed in place, the anti-retreat function can be realized, the structure after the assembly of the first connector 3 and the second connector 4 is more stable, the product quality is higher, the risks of dropping and disconnection of the product during transportation can be avoided, and thus the market competitiveness of the present invention is enhanced.

[0065] Certainly, the above descriptions are only specific embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present utility model shall be included within the scope of the patent application of the present utility model.
