Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a termination shielded single-pair Ethernet connector. Background Art

[0002] In Ethernet communication, cables with four pairs of wires are usually used. Each pair of wires can send and receive data, thus achieving a relatively high transmission rate. However, this configuration may seem too large and complex in some application scenarios, especially when smaller and lighter cables and connectors are required, which is extremely inconvenient to use. The development of single-pair Ethernet connectors is precisely to meet these needs. It only uses one pair of wires, but the working frequency can reach up to 600 MHz, the transmission distance can reach 40 m, or when the rate is reduced to 10 Mbps, the transmission distance can reach 1000 m. Such characteristics enable SPE connectors to be widely used in fields such as automotive, industrial automation, and medical.

[0003] Currently, the existing single-pair Ethernet connectors adopt a welding and injection molding connection method. This method is prone to damaging the wiring layout of the PCB board during welding, affecting the product performance. In addition, the production efficiency of welding is low and the cost is high. Summary of the Invention

[0004] Aiming at the disadvantages of low production efficiency and high cost in the prior art, the utility model provides a termination shielded single-pair Ethernet connector. This connector uses IDC (Insulation Displacement Connection) technology to connect with the wire pair, with simple wiring and convenient installation.

[0005] The invention object of the utility model is realized through the following technical scheme: A termination shielded single-pair Ethernet connector includes two cooperating connectors. Each connector includes a connector body and a tail sleeve. The front end of the connector body is a plug-in part, and the rear end is provided with a cavity. A PCB board and an IDC fixing part are arranged in the cavity. An IDC and a contact piece extending into the plug-in part are welded on the PCB board. The IDC fixing part is sleeved outside the IDC and confines the PCB board in the cavity. The IDC fixing part is detachably installed in the cavity of the connector body, and the tail sleeve is detachably installed at the rear end of the connector body; the plug-in parts of the two connectors cooperate with each other, and the contact pieces inside are electrically connected when the two plug-in parts are connected.

[0006] Preferably, a support block is fixedly arranged on the inner wall of the cavity. One side of the PCB board is attached to the support block, and the other side of the PCB board is attached to the IDC fixing part. The IDC fixing part is clamped with the connector body.

[0007] Preferably, the tail sleeve extends into the cavity and is attached to the side of the IDC fixing part facing away from the PCB board. The tail sleeve is clamped with the connector body.

[0008] Preferably, the IDC fixing member and the tail sleeve are both provided with buckles, and the inner wall of the cavity is provided with a clamping groove that can be clamped with the buckles.

[0009] Preferably, a shielding shell is sleeved outside the connector body, and a clamping member that is clamped with the connector body is fixedly arranged on the shielding shell. A shielding cover is sleeved outside the tail sleeve, and an elastic piece that is clamped with the tail sleeve is fixedly arranged on the shielding cover.

[0010] Preferably, a grounding elastic piece is connected to the shielding cover, and the grounding elastic piece extends into the tail sleeve.

[0011] Preferably, the grounding elastic piece is clamped with the shielding cover.

[0012] Preferably, when the insertion parts of the two connectors are connected to each other, the clamping members in the two connectors are in contact. The clamping members and the shielding cover are made of the same metal material.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model simplifies the cable connection process. Compared with the traditional welding and injection molding methods, IDC connection does not require complex welding processes and injection molding equipment. Only by correctly inserting the wire pair into the IDC can a fast and stable connection be achieved. The operation is simple, the installation is convenient, the production efficiency is improved, and the production cost is reduced. Secondly, the IDC connection has high connection reliability. Since the IDC technology realizes electrical connection by displacing the insulation layer of the wire pair, the connection points are more firm and are not prone to loosening or falling off. In addition, the SPE connector also adopts a shielding design, which can effectively reduce electromagnetic interference and improve the signal transmission quality.

[0019] The following further describes the present utility model in conjunction with the embodiments shown in the drawings: Embodiment

[0020] As Figures 1-3 shown, a terminated shielded single-pair Ethernet connector includes two cooperating connectors. The connector includes a connector body 1 and a ferrule 2. The front end of the connector body 1 is a plug-in portion 3, and a cavity 4 is provided at the rear end. The plug-in portions 3 of the two connectors are plugged into each other. An IDC fixing member 6 and a PCB board 5 are provided in the cavity 4. An IDC 7 and a contact piece 8 extending into the plug-in portion 3 are soldered on the PCB board 5. A support block 9 is fixedly provided on the inner wall of the cavity 4. One side of the PCB board 5 is attached to the support block 9. The setting of the support block 9 leaves a certain gap between the PCB board 5 and the inner wall of the cavity 4 after installation, so that the pins soldered on the PCB board 5 will not press against the inner wall of the cavity 4. Buckles 10 are provided on both the IDC fixing member 6 and the ferrule 2, and a slot 11 capable of being snap-connected with the buckle 10 is provided on the inner wall of the cavity 4. The IDC fixing member 6 is snap-connected to the connector body 1 through the buckle 10 and the slot 11. The other side of the PCB board 5 is attached to the IDC fixing member 6. The PCB board 5 is fixedly installed in the connector body 1 through the IDC fixing member 6 and the support block 9. The ferrule 2 extends into the cavity 4 and is attached to the side of the IDC fixing member 6 facing away from the PCB board 5. The ferrule 2 is detachably snap-connected to the rear end of the connector body 1 through the buckle 10, which can prevent dust and dirt from entering the connector interior. The plug-in portions 3 of the two connectors cooperate with each other, and the contact pieces 8 inside are electrically connected when the two plug-in portions 3 are connected. A shielding case 14 is sleeved outside the connector body 1, and a snap-in member 15 for snap-connecting with the connector body 1 is fixedly provided on the shielding case 14. A shielding cover 12 is sleeved outside the ferrule 2, and an elastic piece 13 for snap-connecting with the ferrule 2 is fixedly provided on the shielding cover 12. A grounding elastic piece 16 is connected to the shielding cover 12, and the grounding elastic piece 16 extends into the ferrule 2. The grounding elastic piece 16 is snap-connected to the shielding cover 12. When the plug-in portions 3 of the two connectors are connected to each other, the snap-in members 15 in the two connectors are attached, and the snap-in member 15 and the shielding cover 12 are made of the same material.

[0021] The assembly and wiring method of the present utility model are as follows:

[0022] First, the PCB board 5 soldered with the IDC 7 and the contact piece 8 is installed in the cavity 4 of the connector body 1, and the PCB board 5 is attached to the support block 9. Then, the IDC fixing member 6 is installed in the cavity 4, and the IDC fixing member 6 is fixedly installed by snap-connecting the buckle 10 on the IDC fixing member 6 into the slot 11 on the connector body 1. At this time, the IDC fixing member 6 is attached to the PCB board 5, and the IDC fixing member 6 and the support block 9 realize the limit installation of the PCB board 5, without the need to fix the PCB board 5 separately, and the installation is more convenient.

[0023] On the inner side of the tail sleeve 2 facing the IDC fixing member 6, two card wire grooves 17 cooperating with the IDC 7 are fixedly provided. The two twisted core wires of the single-pair Ethernet cable are respectively placed into the card wire grooves 17. The tail sleeve 2 is snap-connected into the card slot 11 on the connector body 1 through the snap 10. When the twisted core wires are directly pressed into the IDC 7, the IDC 7 will cut the insulating layer of the twisted core wires and contact and connect with the conductive inner cores inside the twisted core wires. Compared with welding fixation, such operation is convenient, the connection is firm, and it is not easy to loosen or fall off. After the tail sleeve 2 is installed on the connector body 1, the side of the tail sleeve 2 facing away from the PCB board fits with the IDC fixing member 6. The tail sleeve 2 limits the IDC fixing member 6. When the snap 10 on the IDC fixing member 6 is disengaged from the corresponding card slot 11, under the limiting effect of the tail sleeve 2, the IDC fixing member 6 will not fall off either, making the internal structure of the present utility model more stable.

[0024] One end of the grounding elastic piece 16 is connected to the shielding layer of the single-pair Ethernet cable, and the other end of the grounding elastic piece 16 is connected to the shielding cover 12. The shielding cover 12 is in contact with and electrically conducts with the shielding shell 14. The shielding cover 12 and the shielding shell 14 are used in cooperation to cover and shield the connector. When the mutually cooperating connectors are plugged in, the engaging members 15 of the two connectors overlap together to achieve electrical connection. In this way, the shielding layers of the two single-pair Ethernet cables are electrically connected through the connector, enhancing electromagnetic shielding and improving the stability of signal transmission.
