Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a wire harness connector. Background Technology

[0002] Terminal Position Assurance (TPA) is used in wire harness connectors to prevent terminal pins from slipping out of the coil mating structure, ensuring the stability of the coil connection. In existing technology, a secondary locking structure is added to the wire harness connector. Through the synergistic effect of the secondary locking structure and the primary locking structure, a secondary locking function is achieved for the coil, strengthening its holding effect. However, during manufacturing, the primary and secondary locking structures are typically molded on two separate parts. When assembling the coil, the secondary locking structure must be installed after the primary locking is in place. The secondary locking structure requires separate assembly, which carries risks such as improper installation or loss, occupies a separate process step, reduces production efficiency, and increases product manufacturing costs.

[0003] Therefore, how to provide a wire harness connector that can improve assembly efficiency, save production costs, and ensure assembly quality has become an urgent problem to be solved. Summary of the Invention

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0030] In this invention, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0031] This invention provides a wire harness connector, see below. Figures 1 to 5 As shown, it includes: Housing 1, wherein the housing 1 is provided with a first accommodating space 11; A locking mechanism 2 is provided in the first accommodating space 11 and is used to lock the coil 10 once. A secondary locking mechanism 3 is disposed within the first accommodating space 11 and connected to the primary locking mechanism 2. The secondary locking mechanism 3 is jointly limited by the housing 1 and the primary locking mechanism 2 to restrict the movement of the secondary locking mechanism 3 within the first accommodating space 11; and, Cover 4, which is detachably connected to the first end a of the housing 1; When the cover 4 is installed on the first end a of the housing 1, it limits the secondary locking mechanism 3, so that the secondary locking mechanism 3 limits the primary locking mechanism 2, thereby performing secondary locking on the coil 10.

[0032] The wire harness connector of the present invention includes a primary locking mechanism 2, a secondary locking mechanism 3, and a cover 4. The secondary locking mechanism 3 is jointly and movably confined within the first accommodating space 11 by the housing 1 and the primary locking mechanism 2. In use, the primary locking mechanism 2 and the secondary locking mechanism 3 can be pre-assembled within the first accommodating space 11, eliminating the need for separate assembly, saving production processes and costs, and improving production efficiency. Through the mutual cooperation between the primary locking mechanism 2, the secondary locking mechanism 3, and the cover 4, the wire harness connector achieves primary and secondary locking of the coil 10, improving the stability of the coil 10 installation and ensuring assembly quality.

[0033] The secondary locking mechanism 3 is disposed on the outer periphery of the primary locking mechanism 2. The primary locking mechanism 2 includes a first limiting structure 21 for limiting the displacement of the secondary locking mechanism 3 toward the first end a. The housing 1 includes a second end b disposed opposite to the first end a. The primary locking mechanism 2 also includes a second limiting structure 22 for limiting the displacement of the secondary locking mechanism 3 toward the second end b. When the coil 10 is not installed, the secondary locking mechanism 3 is confined within the first accommodating space 11 by the combined limiting action of the first limiting structure 21 and the second limiting structure 22, thus avoiding the risk of the secondary locking mechanism 3 falling off or being lost after assembly.

[0034] See Figures 3 to 9As shown, the locking mechanism 2 includes a first connector 23 and a first elastic arm 24. The first connector 23 includes a core 231 and a partition plate 232 connected to the core 231 and spaced apart from the inner wall of the housing 1. The partition plate 232 divides the first accommodating space 11 into several second accommodating spaces 25. The first elastic arm 24 is disposed in the second accommodating space 25 and spaced apart from the inner wall of the housing 1. A first opening groove 233 is provided on the area corresponding to the core 231 and the first elastic arm 24. The first opening groove 233 and the first elastic arm 24 together form a first mounting hole 234 for accommodating the coil 10. The coil 10 is provided with a coil rib 101. A limiting ring groove 103 is formed between the coil rib 101 and the coil body 102. When the coil 10 is disposed in the first mounting hole 234, the first elastic arm 24 is engaged in the limiting ring groove 103 to lock the coil 10. In use, the coil 10 is inserted into the first mounting hole 234. After the coil 10 is moved into place, the first elastic arm 24 engages with the limiting ring groove 103. The first elastic arm 24 applies force to the coil 10, interfering with its movement and limiting and fixing the coil 10 within the first mounting hole 234, thus locking the coil 10 in place. The first opening groove 233 guides the insertion of the coil 10 and allows multiple coils 10 to be coaxially arranged.

[0035] Optionally, the number of partition plates 232 is at least two; for example, the number of partition plates 232 is four, dividing the first accommodating space 11 into four second accommodating spaces 25, forming four first mounting holes 234, which can then be used to install four coils 10.

[0036] See Figure 2 , Figures 4 to 10 As shown, the secondary locking mechanism 3 includes a first main body 31 circumferentially disposed at the end of the first connector 23 near the first end a, and a support arm 32 and a second elastic arm 33 alternately disposed on the side of the first main body 31 near the second end b. The support arm 32 is disposed between the first elastic arm 24 and the inner wall of the housing 1, and the second elastic arm 33 is disposed between the partition plate 232 and the inner wall of the housing 1. The secondary locking mechanism 3 is disposed within the gap formed between the primary locking mechanism 2 and the inner wall of the housing 1, which can guide the movement of the secondary locking mechanism 3, thereby ensuring the stability of the movement of the secondary locking mechanism 3, and thus ensuring the stability of the installation of the coil 10.

[0037] In some embodiments, the partition plate 232 includes a first sidewall 2321 disposed near the inner wall of the housing 1 and a second sidewall 2322 connected between the first sidewall 2321 and the first opening groove 233; the second elastic arm 33 includes a first limiting portion 331 connected to the first body 31 and a second limiting portion 332 symmetrically disposed at the end of the first limiting portion 331 away from the first body 31, the first limiting portion 331 being disposed between the first sidewall 2321 and the inner wall of the housing 1, the second elastic arm 33 including ... The second limiting part 332 extends inward from the first limiting part 331 to the second sidewall 2322. The first limiting part 331 is gradually inclined inward from the first main body 31. The first limiting structure 21 is a first protrusion provided on the second sidewall 2322. The second limiting part 332 includes a slot 333 that can be engaged with the first protrusion. The second limiting structure 22 is a first stepped part provided on the end of the first sidewall 2321 near the second end b. The first limiting part 331 can abut against the first stepped part. Before the wire is inserted into the first mounting hole 234, the first protrusion is engaged with the slot 333, and the end face of the first limiting part 331 away from the first main body 31 abuts against the first stepped part. The primary locking mechanism 2 and the secondary locking mechanism 3 cooperate and interfere with each other to limit the secondary locking mechanism 3.

[0038] A second step portion 34 is formed between the inner walls of the first main body 31 and the support arm 32. The second step portion 34 is used to limit the movement of the secondary locking mechanism 3 toward the second end b after the interference between the first limiting portion 331 and the first step portion is released. During the process of inserting the coil 10 from the first end a into the first mounting hole 234, as the coil 10 moves toward the second end b in the first mounting hole 234, the coil rib 101 contacts the first elastic arm 24 and the second limiting portion 332 in turn, driving the first elastic arm 24 and the second elastic arm 33 to deflect toward the inner wall of the housing 1, so that the end face of the first elastic arm 24 near the first end a abuts against the end face of the support arm 32 away from the first main body 31. At this time, the secondary locking mechanism is limited by the first protrusion and the end face of the support arm 32 away from the first main body 31, respectively, to limit the secondary locking mechanism.

[0039] After the coil 10 is inserted into the first mounting hole 234, the first elastic arm 24 engages with the limiting annular groove 103 of the coil 10. The end face of the coil rib 101 facing the first end a contacts the first elastic arm 24, thus limiting the position of the coil 10 in the first mounting hole 234 and locking the coil 10. However, due to the elasticity of the first elastic arm 24, if the coil 10 is subjected to force and shakes or tends to move along the first mounting hole 234 during use, there is a risk of unlocking if the force on the coil 10 is too great. (See also...) Figure 12 As shown, the coil 10 of the present invention includes a coil body 102 and a coil rib 101 disposed on the coil body 102. The coil body 102 includes a first segment and a second segment connected to each other. The outer diameter of the first segment is smaller than the outer diameter of the second segment. The coil rib 101 is disposed on the first segment. The limiting annular groove 103 is formed between the coil rib 101 and the second segment.

[0040] When the coil 10 is inserted into the first mounting hole 234, the interaction force between the first elastic arm 24 and the coil rib 101 is released, the first elastic arm 24 is reset and placed in the limiting ring groove 103, the second limiting part 332 is supported by the coil 10 and is subjected to the force of the coil 10, the second elastic arm 33 remains close to the inner wall of the housing 1, the end face of the support arm 32 near the first end a is released from interference with the first elastic arm 24, so that the secondary locking mechanism 3 can move toward the first end a.

[0041] The inner wall of the first body 31 is arc-shaped, and the first mounting hole 234 extends to the area enclosed by the inner wall of the first body 31 and the first opening groove 233. When the coil 10 is installed in the wire harness connector, the coil 10 is located in the space enclosed by the first opening groove 233, the first elastic arm 24 and the first body 31.

[0042] The first elastic arm 24 has a second protrusion 241 at its end near the first end a. The second protrusion 241 is located on the side of the first elastic arm 24 near the first opening groove 233. When the first elastic arm 24 is engaged in the limiting ring groove 103 of the coil 10, the second protrusion 241 is located in the limiting ring groove 103. The end face of the second protrusion 241 near the first end a has a beveled structure. The beveled structure acts as a buffer and guide when the second protrusion 241 contacts the coil rib 101 of the coil 10, preventing the coil 10 from failing to install due to jamming between the second protrusion 241 and the coil rib 101.

[0043] The first elastic arm 24 has a first base 242 at its end near the second end b. The first base 242 is connected between the first elastic arm 24 and the inner wall of the housing 1. The first base 242 provides a connection base for the first elastic arm 24 to the housing 1, while also limiting the end face of the support seat to prevent the secondary locking mechanism from moving beyond its limit.

[0044] The partition plate 232 is provided with a second base 2323 near the second end b, and the second base 2323 is connected between the partition plate 232 and the inner wall of the housing 1. In some embodiments, the primary locking mechanism 2 is integrally formed with the housing 1.

[0045] See Figure 1 and Figure 2 As shown, the cover 4 is detachably connected to the first end a of the housing 1 via a snap fastener assembly 41; when the cover 4 is fixedly connected to the housing 1, the cover 4 limits the secondary locking mechanism 3 between the cover 4 and the housing 1, and the secondary locking mechanism 3 applies a force to the wall surface of the first elastic arm 24 to limit the first elastic arm 24, thereby performing a secondary locking on the coil 10.

[0046] During the installation of the cover 4, the end face of the cover 4 facing the second end b contacts the end face of the secondary locking mechanism 3 facing the first end a, and drives the secondary locking mechanism 3 to move towards the second end b. If the coil 10 is not installed correctly at this time, the first elastic arm 24 and the support arm 32 will still remain in contact with each other, and the movement of the secondary locking mechanism 3 towards the second end b will be restricted. At this time, the state of the secondary locking mechanism 3 can be used to detect whether the coil 10 is installed correctly, thus avoiding the risk of parts being improperly installed or lost at the physical structure level.

[0047] The latching assembly 41 includes latches 411 and latching blocks 412 that engage with each other. When the latches 411 are provided on either the housing 1 or the cover 4, the latching blocks 412 are provided on the other of the housing 1 or the cover 4. For example, the cover 4 is provided with latches 411, and the outer wall of the housing 1 is provided with latching blocks 412 that cooperate with the latches 411.

[0048] The outer wall of the cover 4 is provided with a third protrusion 42, and the second end b of the housing 1 is provided with a slot 12 for the third protrusion 42 to be inserted. The cover 4 and the housing 1 are fixed together by a snap-fit ​​assembly 41 and by limiting the third protrusion 42 and the slot 12, which ensures the stable connection between the cover 4 and the housing 1. At the same time, the slot 12 plays a guiding role when the cover 4 is installed.

[0049] See Figures 1 to 2 and Figure 11 As shown, the cover 4 has a second mounting hole 43 communicating with the first mounting hole 234; the cover 4 includes a second body 44 and a sealing member 45 disposed on the second body 44, and the second mounting hole 43 penetrates the second body 44 and the sealing member 45. When the cover 4 is installed on the housing 1, the sealing member 45 contacts the first body 31. The buckle 411 and the third protrusion 42 are both disposed on the second body 44.

[0050] The method of using the wire harness connector of the present invention includes the following steps: The secondary locking mechanism 3 is pre-assembled onto the primary locking mechanism 2; at this time, the slot 333 of the second elastic arm 33 contacts the first limiting structure 21, i.e. the first protrusion, and the end face of the first limiting part 331 is engaged with the second limiting structure 22, i.e. the first step part; the primary locking mechanism 2 limits the secondary locking mechanism 3, and there is no interference between the first elastic arm 24 and the primary locking mechanism 2.

[0051] Insert the coil 10 into the first mounting hole 234 from the first end a. During the insertion process, the coil rib 101 first contacts the first elastic arm 24, driving the first elastic arm 24 to deflect towards the inner wall of the housing 1, and then contacts the end face of the first limit 331 near the second end b; then it contacts the second limit part 332, driving the second limit part 332 to deflect towards the inner wall of the housing 1, thereby causing the second elastic arm 33 to deflect towards the inner wall of the housing 1 as a whole, and the end face of the first limit part 331 disengages from the first limit structure 21.

[0052] The coil 10 is inserted further until it is fully installed. The coil rib 101 disengages from the first elastic arm 24, and the first elastic arm 24 is confined within the limiting annular groove 103, thus achieving a primary locking of the coil 10. At this time, the outer wall of the first elastic arm 24 is not subjected to force and is movable. If the coil 10 is subjected to force, there is a risk of unlocking. At this time, the end face of the first limiting part 331 and the first limiting structure 21 remain disengaged from each other, and the secondary locking mechanism 3 can move towards the direction closer to the second end b.

[0053] Install the cover 4 and fix it to the first end of the housing 1 via the snap-fit ​​assembly 41. During the installation of the cover 4, the sealing element 45 contacts the first body 31 and drives the secondary locking mechanism 3 to move towards the second end b. After the cover 4 is installed in place, the support arm 32 is inserted into the gap between the first elastic arm 24 and the inner wall of the housing 1. The inner wall of the support arm 32 exerts a force on the outer wall of the first elastic arm 24 for a period of time, limiting the first elastic arm 24 and preventing it from deflecting towards the inner wall of the housing 1, thus maintaining a stable limit on the coil 10 and achieving secondary locking of the coil 10.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above embodiments merely illustrate preferred implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
