Description

Technical Field

[0001] The present invention belongs to the field of connectors, and particularly relates to a cable connector, an assembly method and a connector assembly. Background Art

[0002] In cable connectors, especially LVDS connectors (Low Voltage Differential Signal connectors), upper and lower grounding parts are located on the upper and lower sides of the coaxial cable. When welding the grounding parts, relatively high temperatures will be generated on the upper and lower grounding parts. If an electronic wire is sandwiched between the upper and lower grounding parts, the insulating layer of the electronic wire is easily scalded, resulting in poor insulation withstand voltage. To avoid this defect, the conventional methods are as follows:

[0003] 1. All the wires welded to the LVDS connector are made of coaxial cables, and the electronic wires are cancelled. Disadvantage: For some pins for control signals and power transmission, ordinary electronic wires can be used originally. Therefore, the use of coaxial cables is restricted, resulting in increased costs.

[0004] 2. The coaxial cable and the electronic wire are completely separated and used. One side is all coaxial cables, and the other side is all electronic wires. The coaxial cable is arranged between the upper and lower grounding parts, and the electronic wire is arranged on one side of the grounding part. Disadvantage: The pins for transmitting high-speed signals can only be concentrated on one side, and the pins for transmitting power are concentrated on the other side, which brings great limitations to pin definition and client circuit layout.

[0005] Moreover, in order to give full play to the electromagnetic interference (EMI) shielding effect of the metal shell of the cable connector, the grounding terminal of the cable connector and the shielding layer of the coaxial cable connected to the signal terminal need to be stably conducted with the metal shell.

[0006] Currently, the conventional method for achieving conduction is to conduct through the grounding part with the grounding terminal and the shielding layer of the coaxial cable, and then add solder through the opening on the metal shell to make the metal shell conduct with the grounding part. However, this conventional method has obvious defects. On the one hand, when the opening on the metal shell is small, the tin adding operation is very inconvenient, and poor soldering is likely to occur during the welding process, resulting in the inability to stably conduct between the grounding terminal of the cable connector and the shielding layer of the coaxial cable connected to the signal terminal and the metal shell, thereby affecting the EMI shielding effect of the cable connector, making the cable connector vulnerable to external electromagnetic interference during operation, and reducing the stability and reliability of signal transmission. On the other hand, when the opening on the metal shell is large, the tin is likely to flow during the tin adding process, which may scald the wire, not only damaging the wire, affecting the normal use of the entire connector, but also increasing the defect rate and cost during the production process. Summary of the Invention

[0007] The object of the present invention is to provide a cable connector, an assembly method and a connector assembly to overcome at least one of the above defects in the prior art.

[0008] To achieve this purpose, the present invention adopts the following technical solutions:

[0012] Preferably, after step S6, the following step is further included: Extrude the second grounding member downward so that the second grounding member and the first grounding member are in close contact.

[0013] Preferably, the materials of the upper metal shell and the lower metal shell are both iron, aluminum or copper.

[0014] Preferably, the outer sheath of the coaxial cable is removed by laser, and the insulating layers of the coaxial cable and the electronic wire are removed by laser.

[0015] The present invention also provides a cable connector assembled by using the above cable connector assembly method, including: a conductive terminal group, a coaxial cable, an electronic wire, an upper metal shell, a lower metal shell, a first grounding member, and a second grounding member. The upper metal shell and the lower metal shell are connected to form a housing. The conductive terminal group is arranged in the lower metal shell and extends out of the lower metal shell. One ends of the coaxial cable and the electronic wire both extend into the housing and are electrically connected to the conductive terminal group. The first grounding member and the second grounding member are respectively arranged on both sides of the coaxial cable and are both electrically connected to the shielding layer of the coaxial cable. The insulating layer of the electronic wire is placed on top of the second grounding member.

[0016] Preferably, the first grounding member has an extension part, and the extension part is electrically connected to the lower metal shell.

[0017] Preferably, the first grounding member further includes a main body part and a conductive part. The main body part has a plurality of conductive parts, and the extension part is arranged on the main body part.

[0018] Preferably, both the conductive part and the extension part are integrally formed with the main body part.

[0019] Preferably, the conductive part is arranged on one side of the main body part, and the extension part is arranged on the opposite side of the main body part.

[0020] Preferably, a plurality of conductive parts are spaced apart along the length direction of the main body part.

[0021] Preferably, the first grounding part and the second grounding part are electrically connected.

[0022] Preferably, the upper metal shell and the lower metal shell are connected by a snap connection.

[0023] Preferably, the coaxial cables are divided into several groups, and the electronic wires are arranged at least between two adjacent groups of coaxial cables.

[0024] Preferably, the conductive terminal group includes signal terminals, grounding terminals, and an insulator. The signal terminals and the grounding terminals are both fixed to the insulator. The insulator is installed on the lower metal shell. The first grounding part is electrically connected to the grounding terminal. The conductors of the coaxial cables and the electronic wires are both electrically connected to the signal terminals.

[0025] Preferably, there is a pair of signal terminals between at least two adjacent grounding terminals, and each pair of signal terminals includes at least two signal terminals.

[0026] The present invention also provides an electrical connector assembly, including the above-mentioned cable connector and a docking connector docked with the cable connector.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. Through unique assembly steps and innovative designs, significant progress has been made in avoiding scalding of the insulation layer of the electronic wire, improving the flexibility of wire matching, optimizing pin definitions and circuit layouts, and reducing costs, etc. It has important practical application value and broad market prospects.

[0029] 2. The cable connector structure allows for the reasonable use of electronic wires and coaxial cables in the cable connector. For some cases where ordinary electronic wires can meet the transmission requirements (such as control signals and power transmission), it is not necessary to use all coaxial cables with higher costs. On the premise of ensuring the performance of the connector, the material cost is effectively reduced, the market competitiveness of the product is improved, and a more cost-effective solution is provided for users.

[0030] 3. Through the innovative design of particularly adding an extension part at the first grounding part, it can effectively ensure a stable connection between the first grounding part and the lower metal shell. On this basis, stable conduction between the grounding terminal, the shielding layer, and the shell is further achieved. This connection method can give full play to the electromagnetic interference (EMI) shielding effect of the shell and avoid the problem of scalding the wire in the traditional method. Moreover, the whole operation process is more simple and fast, significantly improving the production efficiency and product quality.

[0031] 4. By conducting each grounding terminal through a plurality of conductive parts, a unified grounding reference plane can be formed, reducing the potential difference between different grounding terminals, reducing signal interference and noise, improving the integrity and stability of signals, and ensuring that the cable connector can accurately transmit signals.

[0032] 5. Both the conductive part and the extension part are integrally formed with the main body part, which not only reduces resistance, but also improves signal stability, and has good mechanical strength and stability, facilitating production.

[0033] 6. The first grounding part and the second grounding part are electrically connected, which not only optimizes the grounding effect, but also equalizes the potential distribution and strengthens the shielding efficiency.

[0034] 7. Since the first grounding part is electrically connected to the lower metal shell through the extension part and there is no need to open a hole and add solder above the upper metal shell, a gap is allowed between the second grounding part and the upper metal shell. The insulating layer of the electronic wire can be placed above the second grounding part, and the electronic wire can be clamped between the coaxial cables, or the coaxial cables and the electronic wires can be arranged alternately.

[0044] Embodiment 1:

[0045] The cable connector assembly method provided in this embodiment, the cable connector in this embodiment is an LVDS connector, and includes the following steps:

[0046] S0: Assemble the conductive terminal group 3 on the lower metal shell 2.

[0047] S1: Place the coaxial cable 4 and the electronic wire 5, divide the coaxial cable 4 into left and right groups, and place the electronic wire 5 between the left and right groups of coaxial cables 4.

[0048] S2: Fold the electronic wire 5 back, and use a laser to remove the outer sheath of the coaxial cable 4, so that a part of the shielding layer 8 of the coaxial cable 4 is exposed.

[0049] S3: Weld the second grounding member 7 and the first grounding member 6 on the upper and lower surfaces of the exposed shielding layer 8 of the coaxial cable 4 respectively, and the second grounding member 7 is located above the first grounding member 6.

[0050] S4: Fold the electronic wire 5 back so that its insulating layer 9 is placed above the second grounding member 7.

[0051] S5: Use a laser to remove the insulating layers 9 of the coaxial cable 4 and the electronic wire 5, so that a part of the conductors 10 of the coaxial cable 4 and the electronic wire 5 are exposed.

[0052] S6: Weld the conductor 10 of the coaxial cable 4 and the conductor 10 of the electronic wire 5 together to the conductive terminal group 3, weld the first grounding member 6 to the grounding terminal 32 of the conductive terminal group 3, and press the extension portion 61 of the first grounding member 6 downward to weld it to the lower metal shell 2, thereby realizing a reliable electrical connection between the extension portion 61 and the lower metal shell 2.

[0053] S61: Squeeze the second grounding member 7 downward so that the second grounding member 7 and the first grounding member 6 are in close contact.

[0054] S7: Assemble the upper metal shell 1. In this embodiment, the upper metal shell 1 and the lower metal shell 2 are both made of iron.

[0055] By folding the electronic wire 5 before welding the first grounding piece 6, the coaxial line 4 and the second grounding piece 7, and then folding it back and placing it on the first grounding piece 6 after the above components are welded, the electronic wire 5 is cleverly avoided from being affected by the welding process, and the risk of the insulating layer 9 of the electronic wire 5 being burned is completely eliminated. This innovative design allows the electronic wire 5 to be safely set between two groups of coaxial lines 4, or alternately set with the coaxial line 4, fundamentally solving the problem of poor insulation withstand voltage of the electronic wire 5 in the traditional process. It breaks the limitation of the traditional method on welding wires, and innovatively realizes the clamping of the electronic wire 5 between the coaxial lines 4, or the alternation of the coaxial line 4 and the electronic wire 5. This breakthrough makes the LVDS connector rich in diversity in the types and matching of welding wires, and can flexibly select the appropriate wire combination according to different application scenarios and needs, greatly expanding the application range of the connector. It allows more flexible allocation of pin functions, and the pins for transmitting high-speed signals and the pins for transmitting power are no longer constrained by the distribution of wires, and can be more reasonably laid out according to actual needs. This not only improves the pin definition flexibility of the LVDS connector, but also provides a larger design space for the client's line layout, which can better meet the requirements of complex circuit design. In addition, there is no need to use all coaxial lines 4. The pins that could originally use ordinary electronic lines 5 to transmit control signals and power can still use low-cost electronic lines 5. Under the premise of ensuring the performance of the connector, the material cost is significantly reduced and the market competitiveness of the product is improved.

[0056] Through unique assembly steps and innovative design, the present invention has made significant progress in avoiding burns to the insulation layer 9 of the electronic wire 5, improving the flexibility of wire matching, optimizing pin definition and circuit layout, and reducing costs. It has important practical application value and broad market prospects.

[0057] Embodiment 2:

[0058] like Figures 1 to 5 As shown, this embodiment provides a cable connector, which is assembled using the cable connector assembly method of embodiment 1, including:

[0059] A conductive terminal group 3, a coaxial cable 4, an electronic wire 5, an upper metal shell 1, a lower metal shell 2, a first grounding member 6, and a second grounding member 7. The upper metal shell 1 and the lower metal shell 2 are connected to form a housing. The conductive terminal group 3 is disposed in the lower metal shell 2 and extends out of the lower metal shell 2. The rear ends of the coaxial cable 4 and the electronic wire 5 both extend into the housing and are electrically connected to the conductive terminal group 3. The first grounding member 6 and the second grounding member 7 are respectively disposed on both sides of the coaxial cable 4 and are both electrically connected to the shielding layer 8 of the coaxial cable 4. The insulating layer 9 of the electronic wire 5 is placed above the second grounding member 7. In this embodiment, the second grounding member 7 is located above the first grounding member 6.

[0060] Through the structural design of the present invention and combined with a unique assembly method, when welding the first grounding member 6, the coaxial cable 4, and the second grounding member 7, the insulating layer 9 of the electronic wire 5 will not be scalded by high temperature, effectively ensuring the insulation withstand voltage performance of the electronic wire 5, improving the electrical safety and stability of the cable connector, and reducing the risk of failures caused by poor insulation. Both the first grounding member 6 and the second grounding member 7 are electrically connected to the shielding layer 8 of the coaxial cable 4, and the upper metal shell 1 and the lower metal shell 2 are connected to form a housing. This structure can form a relatively complete electromagnetic shielding system, effectively blocking the influence of external electromagnetic interference on the signals transmitted in the coaxial cable 4, and at the same time preventing the internal signals from radiating outward to interfere with other electronic devices. For components such as LVDS connectors that transmit high-speed signals, good electromagnetic shielding performance is crucial for ensuring the accuracy and stability of signal transmission. This structure allows for the reasonable use of the electronic wire 5 and the coaxial cable 4 in the cable connector. For some cases where the ordinary electronic wire 5 can meet the transmission requirements (such as control signals and power transmission), there is no need to use all the relatively expensive coaxial cables 4. On the premise of ensuring the performance of the connector, the material cost is effectively reduced, the market competitiveness of the product is improved, and a more cost-effective solution is provided for users.

[0061] Among them, the first grounding member 6 has an extension portion 61, and the extension portion 61 is electrically connected to the lower metal shell 2. By the innovative design of particularly adding the extension portion 61 at the first grounding member 6, it can effectively ensure a stable connection between the first grounding member 6 and the lower metal shell 2. On this basis, a stable conduction between the grounding terminal 32, the shielding layer 8, and the housing is further achieved. This connection method can fully utilize the electromagnetic interference (EMI) shielding effect of the housing, avoiding the problem of scalding the wire materials that may occur in the traditional method. Moreover, the whole operation process is more simple and fast, significantly improving the production efficiency and product quality.

[0062] Among them, the first grounding member 6 further includes a main body portion 62 and a conductive portion 63. The main body portion 62 has a plurality of conductive portions 63, and the extension portion 61 is provided on the main body portion 62. Specifically, the conductive portions 63 are provided on the rear side of the main body portion 62, and the extension portion 61 is provided on the front side of the main body portion 62. The plurality of conductive portions 63 are spaced apart along the length direction of the main body portion 62. By conducting each grounding terminal 32 through the plurality of conductive portions 63, a unified grounding reference plane can be formed, reducing the potential difference between different grounding terminals 32, reducing signal interference and noise, improving the integrity and stability of the signal, and ensuring that the cable connector can accurately transmit the signal.

[0063] Among them, both the conductive portion 63 and the extension portion 61 are integrally formed with the main body portion 62. This not only reduces the resistance, but also improves the signal stability, and has good mechanical strength and stability, facilitating production.

[0064] Among them, the first grounding member 6 and the second grounding member 7 are electrically connected. This not only optimizes the grounding effect, but also equalizes the potential distribution and enhances the shielding efficiency. In this embodiment, the first grounding member 6 and the second grounding member 7 are brought into close contact by extrusion to achieve electrical connection. In other embodiments, the first grounding member 6 and the second grounding member 7 can also be welded to achieve electrical connection.

[0065] Among them, the upper metal shell 1 and the lower metal shell 2 are connected by a snap-fit method. The connection is achieved by the snap-fit method, improving the convenience of assembly and disassembly.

[0066] Among them, the coaxial cables 4 are divided into several groups, and the electronic wires 5 are disposed at least between two adjacent groups of coaxial cables 4. In this embodiment, there are two groups of coaxial cables 4 in total, and the electronic wires 5 are clamped between the left and right groups of coaxial cables 4. In other embodiments, the coaxial cables 4 and the electronic wires 5 can also be arranged alternately. Since the first grounding member 6 is electrically connected to the lower metal shell 2 through the extension portion 61 and there is no need to open a hole above the upper metal shell 1 for soldering, a gap is allowed between the second grounding member 7 and the upper metal shell 1, and the insulating layer 9 of the electronic wire 5 can be placed above the second grounding member 7, enabling the electronic wire 5 to be clamped between the coaxial cables 4 or achieving an alternating arrangement of the coaxial cables 4 and the electronic wires 5.

[0067] Among them, the conductive terminal group 3 includes signal terminals 31, ground terminals 32, and an insulator 33. The signal terminals 31 and the ground terminals 32 are both fixed to the insulator 33, and the insulator 33 is installed on the lower metal shell 2. The first grounding member 6 is electrically connected to the ground terminal 32, and the conductors 10 of the coaxial cable 4 and the electronic wire 5 are both electrically connected to the signal terminal 31. There is a signal terminal pair including at least two signal terminals 31 between at least one pair of adjacent ground terminals 32. For a system adopting differential signal transmission mode (such as many high-speed data interfaces), the presence of the ground terminals 32 can better support the transmission of differential signals, further improving the anti-interference ability and transmission performance of the signals. Differential signal pairs have a strong ability to suppress common-mode interference, and the reasonable layout of the ground terminals 32 can enhance this suppression effect.

[0068] Embodiment Three:
