Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a pre-molded Ethernet connector. Background Technology

[0002] With the rapid development of network technology, Ethernet, as the mainstream network communication technology, has seen continuous improvements in bandwidth and transmission speed. However, this has amplified the problems of mutual interference and return loss during high-speed signal transmission, severely restricting signal transmission quality and efficiency. Category 6 (Category 6) network cables, with their bandwidth of up to 500MHz and maximum transmission speed of 10Gb / s, are widely used. However, the connectors and wire harnesses used with these cables still face challenges in terms of signal transmission quality. Traditional connector designs and wire harnesses cannot meet the high standards of Category 6 (Category 6) network cables, and have shortcomings in terms of return and crosstalk adjustment.

[0003] Traditional gold-plated wire arrangements are divided into two types: A: Two-row arrangement (top: 1236, bottom: 4578); B: Single-row arrangement (12364578). This design, because the two pairs of wires need to cross, significantly impacts the product's crosstalk performance. Furthermore, the semi-enclosed shielding of traditional connectors requires secondary riveting of the cable into a triangular clip on the connector after assembly to tighten the cable and prevent it from coming loose. This riveting process inevitably damages the cable's structure. After the cable is assembled in a traditional connector, a gap exists between the cable and the connector. During the pre-injection molding process, high temperature and pressure compress this gap, causing structural deformation of the cable and affecting its characteristic impedance. There are areas for improvement in the existing technology. Summary of the Invention

[0004] This utility model addresses the aforementioned existing situation by providing a pre-molded Ethernet connector, comprising a housing, a core, and a tail sleeve fitted onto a cable. The core contains gold pins for connection to an external socket. An upper bracket and a lower bracket for fixing the cable are provided between the tail sleeve and the housing. The upper and lower brackets are respectively provided with pressure grooves for clamping the cable. The tail sleeve abuts against the upper and lower brackets. The upper bracket, lower bracket, and tail sleeve are all covered with a plastic sleeve. The gold pins are arranged at positions 3456 on the upper layer and 1278 on the lower layer on the core.

[0005] Preferably, the upper bracket and the lower bracket are respectively provided with an upper insertion part and a lower insertion part for insertion into the housing at one end facing the housing. The upper insertion part is provided with an insertion plate for insertion into the housing at one end facing the housing. A protrusion for locking into the housing is fixedly provided on the lower insertion part. A first slot for locking the protrusion is provided in the housing.

[0006] Preferably, the end of the insert plate facing the insert core is fixedly provided with a plurality of downwardly extending partitions for separating cables.

[0007] Preferably, the upper bracket has second slots on both sides for connecting the lower bracket, and the lower bracket has buckles that extend upward and engage with the second slots on both sides.

[0008] Preferably, the tail sleeve has two locking blocks on its outer periphery facing the upper bracket, and the upper bracket has a third locking groove for locking the locking blocks. The two locking blocks are symmetrically arranged on both sides of the tail sleeve.

[0009] Preferably, the tail sleeve has two positioning blocks on its outer periphery facing the upper bracket. The upper and lower brackets are respectively provided with positioning grooves for engaging the positioning blocks. The two positioning blocks are located in the same straight line direction and are perpendicular to the straight line direction of the two aforementioned locking blocks.

[0010] Preferably, the plastic sleeve is injection molded to cover the outer periphery of the upper bracket, lower bracket and tail sleeve.

[0011] Preferably, the volume of the upper gold needle is 2.9-3.2 mm³, and the volume of the lower gold needle is 2.5-2.8 mm³.

[0012] Preferably, the tail sleeve is bent at a 90-degree angle.

[0013] Compared with the prior art, this utility model fixes the cable by interlocking the upper and lower brackets and pressing them against the cable during installation. The plastic sleeve is then injection molded onto the upper, lower, and tail sleeves, ensuring that the high temperature and high pressure of the injection molding material will not damage or compress the cable. This ensures the consistency of the characteristic impedance of the cable and connector, thereby ensuring the performance indicators of return loss. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] Example 1:

[0023] like Figure 1-5 As shown, a pre-molded Ethernet connector includes a housing 1, a ferrule 2, and a tail sleeve 3 fitted onto a cable. The ferrule 2 contains a gold pin 4 for connection to an external socket. An upper bracket 5 and a lower bracket 6 for securing the cable are provided between the tail sleeve 3 and the housing 1. The upper bracket 5 and lower bracket 6 are inserted into the housing 1 and each has a clamping groove 7 for securing the cable. The tail sleeve 3 abuts against the upper bracket 5 and lower bracket 6. A plastic sleeve 8 covers the outer periphery of the upper bracket 5, lower bracket 6, and tail sleeve 3. The plastic sleeve 8 is formed by injection molding. During installation, the upper bracket 5 and lower bracket 6 interlock and press against the cable to secure it. A plastic sleeve 8 is then injection-molded onto the upper bracket 5, lower bracket 6, and tail sleeve 3, forming a single unit. This isolates the high temperature and pressure of the injection molding process from the tail sleeve 3, upper bracket 5, lower bracket 6, and housing 1, ensuring that the high temperature and pressure of the injection-molded plastic material will not damage or compress the cable. This guarantees the consistency of the characteristic impedance of the cable and connector, ensuring the return loss performance indicators and meeting the performance requirements of Category 6a patchcord after injection molding. It also significantly reduces the performance margin requirements for the cable.

[0024] The upper bracket 5 and the lower bracket 6 are respectively provided with an upper insertion part 9 and a lower insertion part 10 for insertion into the housing 1 at their ends facing the housing 1. The upper insertion part 9 is provided with an insertion plate 11 for insertion into the housing 1 at its end facing the housing 1. The lower insertion part 10 is fixedly provided with a protrusion 12 for engaging with the housing 1. The housing 1 has a first slot 13 for engaging the protrusion 12. The upper bracket 5 has a second slot 15 for connecting the lower bracket 6 on both sides. The lower bracket 6 has a buckle 16 that extends upward and engages with the second slot 15 on both sides. The tail sleeve 3 has two locking blocks 17 on its outer periphery facing the upper bracket 5. The upper bracket 5 has a third slot 18 for engaging the locking blocks 17. The two locking blocks 17 are symmetrically arranged on both sides of the tail sleeve 3. Two positioning blocks 19 are provided on the outer periphery of the tail sleeve 3 facing the upper bracket 5. The upper bracket 5 and the lower bracket 6 are respectively provided with positioning grooves 20 for engaging the positioning blocks 19. The two positioning blocks 19 are located in the same straight line direction and are perpendicular to the straight line direction of the two aforementioned locking blocks 17.

[0025] During installation, the tail sleeve 3 is fitted onto the cable. The upper bracket 5 is pressed against the tail sleeve 3 and the cable. The locking block 17 on the tail sleeve 3 is engaged into the third locking groove 18 of the upper bracket 5, and the positioning block 19 on the tail sleeve 3 is engaged into the positioning groove 20 and abuts against the upper bracket 5. The lower bracket 6 is pressed against the cable and the tail sleeve 3 below the cable and fastened to the lower part of the upper bracket 5. The buckle 16 on the lower bracket 6 is engaged into the second locking groove 15 after deformation, completing the installation between the upper bracket 5, the lower bracket 6 and the tail sleeve 3. The upper bracket 5 and the lower bracket 6 are then inserted into the housing 1. The protrusion 12 on the lower bracket 6 is engaged into the first locking groove 13 on the housing 1, completing the connection between the lower bracket 6 and the housing 1.

[0026] The gold pins 4 are arranged at upper layer 3456 and lower layer 1278 on the ferrule 2, respectively. This arrangement improves crosstalk performance. The volume of the upper gold pins 4 is 3 mm³, and the volume of the lower gold pins 4 is 2.6 mm³. Several downward-extending partitions 14 are fixedly provided at the end of the insert plate 11 facing the ferrule 2 to separate the cables. The upper bracket 5, lower bracket 6, and partitions 14 fix the distance between different cable pairs. The coupling effect generated by the different distances between the gold pins 4 and the partitions 14 suppresses crosstalk between different cable pairs.

[0027] Example 2:

[0028] The difference from the embodiment is that, as Figure 6 As shown, the tail sleeve 3 is bent at a 90-degree angle. By designing the tail sleeve 3 at different angles, different cable exit angles can be achieved.

[0029] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
