Description

Technical Field

[0001] This utility model relates to a network cable pliers, and more specifically, to a portable mini network cable pliers. Background Technology

[0002] A network cable crimping tool is a specialized tool used to create connectors for network cables and telephone lines. It is primarily used to strip cable sheaths, cut excess wire, and crimp terminals (such as RJ45 connectors) to achieve stable and reliable signal transmission. Its core functions include wire stripping, cutting, and crimping, and it supports various connector types, such as 4P (telephone line), 6P (telephone or network line), and 8P (network cable RJ45 connectors). Common network cable crimping tools are available in single-use, two-way, and three-way types to accommodate different cable handling needs; for example, a three-way crimping tool is compatible with multiple connector sizes. Some users now prefer mini network cable crimping tools for portability, but small network cable crimping tools still have significant shortcomings in structural strength and quality.

[0003] For example, Chinese Patent Publication No. CN208336769U, published on January 4, 2019, entitled "Portable Network Cable Cutter," discloses a portable mini network cable cutter. The cutter includes a base, comprising a first plate-shaped base with a pressure holder groove at its top and a pressure holder within the groove. A second plate-shaped base is located on one side of the first plate-shaped base, and a third plate-shaped base is located on the other side. A crystal head limiting block is located on the side of the third plate-shaped base away from the first plate-shaped base. The cutter also includes a pressure rod, comprising a force-applying part with a force-receiving part at the bottom of one end. The end of the force-applying part away from the force-receiving part is hinged to the first plate-shaped base, and the other end is hinged to the pressure holder. This network cable cutter is smaller in size, suitable for simple equipment maintenance, and easy to carry. However, the internal structure of this mini network cable crimper uses plate-like or sheet-like structures as a frame, resulting in low overall strength. During use and under stress, the various structures are prone to tilting or even breaking, thus reducing the manufacturing quality of the network cable connector. Utility Model Content

[0004] This invention overcomes the problems of low structural strength and easy deformation and skew of the crimping head in small network cable pliers, and provides a portable mini network cable pliers. This solution effectively increases the strength of the pliers body structure and the crimping head structure, ensuring the quality of RJ45 connectors made with small network cable pliers.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a portable mini network cable crimper, comprising a base and a crimping head assembly slidably connected to the base. The crimping head assembly includes a first crimping head and a second crimping head disposed on both sides of the base and moving synchronously. The first crimping head includes a first crimping head and a second crimping head, and the second crimping head includes a third crimping head aligned with the first crimping head. The base is provided with a crimping interface, and the crimping interface has a through hole. A fourth crimping head aligned with the second crimping head and moving synchronously is slidably connected to the through hole. The crimping head assembly moves through the base as a guide, which can effectively improve the stability of the crimping head assembly during movement. At the same time, the base is a block structure with a certain structural strength. The through hole inside the base where one of the crimping heads is arranged further improves the movement trajectory of the crimping head, which can effectively prevent the crimping head assembly from deflecting or breaking during the crimping of RJ45 connectors.

[0006] Preferably, guide plates are provided on both sides of the base, and guide holes are provided on the guide plates. The first crimping head and the second crimping head slide within the guide holes on both sides of the base. The guide plates can limit and guide the crimping head assembly, ensuring the movement trajectory of the crimping head assembly and completing the crimping operation.

[0007] Preferably, the substrate is provided with a first guide groove, which communicates with the through hole. One end of the fourth pressure head passes through the through hole into the pressure interface, and the other end is provided with a first guide shaft fixedly connected to the first pressure connector and the second pressure connector. The first guide shaft is slidably connected to the first guide groove. The fourth pressure head is connected to the first pressure connector and the second pressure connector through the first guide shaft, and two sets of connecting shafts are formed on the first pressure connector and the second pressure connector, making the connection between the three more stable and preventing the pressure head assembly from deflecting away from the outside of the substrate during movement.

[0008] Preferably, the system also includes a drive unit hinged to the guide plate. The base also has a second guide groove. A connector is provided between the drive unit and the base. One end of the connector is hinged to the drive unit, and the other end has a second guide shaft fixedly connected to the first and second pressure heads. The second guide shaft is slidably connected to the second guide groove. The drive unit is rotatable relative to the guide plate. The drive unit is connected to the pressure head assembly on the base via the connector. When the drive unit operates, it provides force to the pressure head assembly.

[0009] Preferably, the driving unit is L-shaped, with a pressure blade at a right-angle position. A pressure blade portion is provided on the guide plate corresponding to the pressure blade position, and a pressure blade plate is provided on the pressure blade portion. The right-angle position of the driving unit is located inside the driving unit and close to the rotation fulcrum. By applying force to the driving unit, a larger lever arm can be formed at the pressure blade position, which is more conducive to the wire cutting operation of the wire cutters. The pressure blade plate is used to cooperate with the pressure blade to complete the wire cutting operation.

[0010] Preferably, the pressure blade portion is provided with a stripping groove on the outside of the pressure blade plate. The stripping groove on the pressure blade portion enables the stripping operation of the network cable without damaging the internal conductors.

[0011] Preferably, the device also includes a housing, which comprises a first housing and a second housing, the first housing and the second housing being respectively snapped onto the bottom of the base and the top of the drive unit. The first housing and the second housing provide protection for the network cable clamp and also improve the user's handling comfort.

[0012] Preferably, the first housing has a clearance groove on the hinge side near the drive unit. When the drive unit rotates relative to the guide plate, the bottom of the drive unit near the hinge will rotate to the outside of the bottom of the guide plate. The clearance groove on the first housing can accommodate the part that rotates to the outside, ensuring that the drive unit can rotate normally and realize the crimping operation of the network cable clamp.

[0013] Preferably, the substrate also has perforated holes. These perforated holes reduce the overall weight of the substrate and improve the portability of the network cable clamp.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) The overall structure of the network cable crimper is more stable and the structural strength is higher. During the process of making RJ45 network cable crimpers, the crimping head assembly is not prone to deformation or skew; (2) It is suitable for making various types of RJ45 heads, and the crimping head assembly is located on the outside, making it easy to disassemble and replace different types of crimping head structures; (3) It is easy to disassemble and maintain, lightweight and compact, and easy to carry and use.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0031] Example 1: As Figures 1 to 7 The portable mini network cable crimper shown includes a base assembly and a drive unit 4. The base assembly is hinged to the drive unit 4, allowing the drive unit 4 to rotate relative to the base assembly. The base assembly includes a base 1, a guide plate, and a crimping head assembly 2. The base 1 is a block structure. The guide plate includes a first guide plate 3.1 and a second guide plate 3.2, which are respectively arranged on both sides of the thickness direction of the base 1. The crimping head assembly 2 is located inside the guide plate and also inside the base 1. The crimping head assembly 2 is slidably connected to the guide plate and the base 1, and is hinged to the drive unit 4. When the drive unit 4 rotates relative to the base assembly, it can drive the crimping head assembly 2 to slide on the base assembly, thereby creating a crimping effect and realizing the fabrication of the network cable RJ45 connector.

[0032] Specifically, a first pressure interface 1.1 and a second pressure interface 1.2 are arranged on the substrate 1, such as... Figures 2 to 4 As shown, the first crimping interface 1.1 is located above the second crimping interface 1.2 and in the same vertical direction. Both the first crimping interface 1.1 and the second crimping interface 1.2 have stepped inner walls to accommodate the crystal head structure and secure it. The upper length of the base 1 is greater than the lower length. A first guide groove 1.4 is provided on the upper side of the base 1, corresponding to the position of the first crimping interface 1.1, and a second guide groove 1.5 is provided on the lower side of the base 1, corresponding to the position of the second crimping interface 1.2. The first guide groove 1.4 and the second guide groove 1.5 are located on the thickness section of the base 1. The first guide groove 1.4 connects to the first crimping interface 1.1, and a through hole 1.3 is formed between the first guide groove 1.4 and the first crimping interface 1.1. Figure 5 As shown, the first guide groove 1.4 includes a horizontal groove and a vertical groove, which intersect perpendicularly to each other. The second guide groove 1.5 has only a horizontal groove. The first guide groove 1.4 and the second guide groove 1.5 are used to allow the pressure head assembly 2 to slide on the base 1. Holes 1.6 are also arranged on the base 1. The holes 1.6 can effectively reduce the overall weight of the base 1, which is beneficial to the portability of the crimping tool.

[0033] Furthermore, the first guide plate 3.1 and the second guide plate 3.2 are arranged on both sides of the base 1 and fixed together, as shown below. Figure 2As shown, the first guide plate 3.1 is located on the right, and the second guide plate 3.2 is located on the left. The first guide plate 3.1 and the second guide plate 3.2 are respectively provided with a first guide hole 3.11 and a second guide hole 3.21. The positions of the first guide hole 3.11 and the second guide hole 3.21 correspond to the positions of the pressure interfaces (first pressure interface 1.1 and second pressure interface 1.2). The length of the first guide plate 3.1 and the second guide plate 3.2 is greater than the length of the base 1. The pressure head assembly 2 includes a first pressure connector 2.1 and a second pressure connector 2.2. The length of the first guide hole 3.11 and the second guide hole 3.21 is greater than the length of the first pressure connector 2.1 and the second pressure connector 2.2. Simultaneously, the internal contours of the first guide hole 3.11 and the second guide hole 3.21 are adapted to the external shapes of the first pressure connector 2.1 and the second pressure connector 2.2, respectively. The first pressure connector 2.1 and the second pressure connector 2.2 can slide within the first guide hole 3.21 and the second guide hole 3.21, respectively. The first crimp connector 2.1 includes a first crimp head 2.11 and a second crimp head 2.12. The position of the first crimp head 2.1 corresponds to the position of the second crimp interface 1.2, and the position of the second crimp head 2.1 corresponds to the position of the first crimp interface 1.1. The second crimp connector 2.2 includes a third crimp head 2.21. The position of the third crimp head 2.21 corresponds to the position of the second crimp interface 1.2, that is, the position of the first crimp head 2.11 corresponds to the position of the third crimp head 2.21. An additional fourth crimp head 2.3 is slidably connected in the through hole 1.3 of the base 1. The position of the fourth crimp head 2.3 corresponds to the position of the first crimp interface 1.1.

[0034] It is understood that the first crimp head 2.11, the second crimp head 2.12, and the third crimp head 2.21 are crimp head structures located on the side of the base 1, while the fourth crimp head 2.3 is a crimp head structure independent of the first crimp head 2.1 and the second crimp head 2.2. The fourth crimp head 2.3 is located inside the through hole 1.3 of the base 1. The first crimp head 2.1, the second crimp head 2.2, and the fourth crimp head 2.3 move in the same direction and move synchronously. Among them, the first crimp head 2.11 and the second crimp head 2.12 are used to squeeze the wire groove at the tail of the RJ45 connector, so that the outer sheath of the network cable is tightened and fixed. The third crimp head 2.21 and the fourth crimp head 2.3 are used for the crimping operation of the RJ45 connector, so that an effective connection (electrical connection) is formed between the network cable and the RJ45 connector.

[0035] Furthermore, such as Figures 4 to 6As shown, the fourth pressure head 2.3 is located between the first pressure head 2.1 and the second pressure head 2.2. The fourth pressure head 2.3, the first pressure head 2.1, and the second pressure head 2.2 are fixedly connected together by the first guide shaft 5.1, thus enabling the first pressure head 2.1, the second pressure head 2.2, and the fourth pressure head 2.3 to move synchronously in the same direction. A connecting piece 6 is also provided between the first pressure head 2.1 and the second pressure head 2.2. The first pressure head 2.1, the second pressure head 2.1, and the connecting piece 6 are connected together by the second guide shaft 5.2, thus enabling the connecting piece 6, the first pressure head 2.1, and the second pressure head 2.2 to move synchronously. One end of the connecting piece 6 is connected to the first pressure head 2.1 and the second pressure head 2.2 via the second guide shaft 5.2, while the other end is hinged to the drive unit 4. In other words, when the drive unit 4 is activated, it can drive the connector 6 to move, which in turn drives the first crimping head 2.1, the second crimping head 2.2 and the fourth crimping head 2.3 to move, thereby realizing the operation of making crystal heads.

[0036] It should be noted that the first guide shaft 5.1 is located within the first guide groove 1.4 of the base 1, and the second guide shaft 5.2 is located within the second guide groove 1.5 of the base 1. The first guide groove 1.4 includes a horizontal groove and a vertical groove. The vertical groove accommodates the vertically placed fourth pressure head 2.3, which slides within the vertical groove. The horizontal groove accommodates the first guide shaft 5.1, which moves within the horizontal groove. The connecting member 6 includes two oblong plate structures, spaced apart. One end of each oblong plate is connected to the second guide shaft 5.2, and the other end is hinged to the drive unit 4. The position of the second guide groove 1.5 corresponds to the vertical groove in the first guide groove 1.4. The second guide shaft 5.2, located in the middle of the two oblong plate structures, is located within the second guide groove 1.5. Thus, the first pressure head 2.1, the second pressure head 2.2, and the fourth pressure head 2.3 are fixed to the base 1, forming a stable connection. Furthermore, since the first crimp connector 2.1, the second crimp connector 2.2, and the fourth crimp connector 2.3 are all thin-plate structures, during the manufacturing process of the crystal head, the forces on the first crimp connector 2.1, the second crimp connector 2.2, and the fourth crimp connector 2.2 are all perpendicular to the thickness direction of the thin plate. This can easily cause misalignment between the crimp connectors, with the misalignment direction only towards the outer sides of the substrate 1, which can easily lead to a decrease in the quality of the crystal head manufacturing and result in non-compliance. Therefore, using an independent fourth crimp connector 2.3 positioned between the first crimp connector 2.1 and the second crimp connector 2.2 can significantly improve the stability of the three components. At the same time, the first crimp connector 2.1 and the second crimp connector 2.2 are connected by two shafts, the first guide shaft 5.1 and the second guide shaft 5.2, which greatly improves the connection strength and structural stability between the first crimp connector 2.1 and the second crimp connector 2.2, making it less prone to the aforementioned misalignment, thereby ensuring the quality of the crystal head manufacturing and improving the pass rate.

[0037] Example 2: Figures 1 to 7 The portable mini network cable crimper shown includes a base assembly and a drive unit 4. The base assembly is hinged to the drive unit 4, allowing the drive unit 4 to rotate relative to the base assembly. The base assembly includes a base 1, a guide plate, and a crimping head assembly 2. The base 1 is a block structure. The guide plate includes a first guide plate 3.1 and a second guide plate 3.2, which are respectively arranged on both sides of the thickness direction of the base 1. The crimping head assembly 2 is located inside the guide plate and also inside the base 1. The crimping head assembly 2 is slidably connected to the guide plate and the base 1, and is hinged to the drive unit 4. When the drive unit 4 rotates relative to the base assembly, it can drive the crimping head assembly 2 to slide on the base assembly, thereby creating a crimping effect and realizing the fabrication of the network cable RJ45 connector.

[0038] Specifically, a first pressure interface 1.1 and a second pressure interface 1.2 are arranged on the substrate 1, such as... Figures 2 to 4 As shown, the first crimping interface 1.1 is located above the second crimping interface 1.2 and in the same vertical direction. Both the first crimping interface 1.1 and the second crimping interface 1.2 have stepped inner walls to accommodate the crystal head structure and secure it. The upper length of the base 1 is greater than the lower length. A first guide groove 1.4 is provided on the upper side of the base 1, corresponding to the position of the first crimping interface 1.1, and a second guide groove 1.5 is provided on the lower side of the base 1, corresponding to the position of the second crimping interface 1.2. The first guide groove 1.4 and the second guide groove 1.5 are located on the thickness section of the base 1. The first guide groove 1.4 connects to the first crimping interface 1.1, and a through hole 1.3 is formed between the first guide groove 1.4 and the first crimping interface 1.1. Figure 5 As shown, the first guide groove 1.4 includes a horizontal groove and a vertical groove, which intersect perpendicularly to each other. The second guide groove 1.5 has only a horizontal groove. The first guide groove 1.4 and the second guide groove 1.5 are used to allow the pressure head assembly 2 to slide on the base 1. Holes 1.6 are also arranged on the base 1. The holes 1.6 can effectively reduce the overall weight of the base 1, which is beneficial to the portability of the crimping tool.

[0039] Furthermore, the first guide plate 3.1 and the second guide plate 3.2 are arranged on both sides of the base 1 and fixed together, as shown below. Figure 2As shown, the first guide plate 3.1 is located on the right, and the second guide plate 3.2 is located on the left. The first guide plate 3.1 and the second guide plate 3.2 are respectively provided with a first guide hole 3.11 and a second guide hole 3.21. The positions of the first guide hole 3.11 and the second guide hole 3.21 correspond to the positions of the pressure interfaces (first pressure interface 1.1 and second pressure interface 1.2). The length of the first guide plate 3.1 and the second guide plate 3.2 is greater than the length of the base 1. The pressure head assembly 2 includes a first pressure connector 2.1 and a second pressure connector 2.2. The length of the first guide hole 3.11 and the second guide hole 3.21 is greater than the length of the first pressure connector 2.1 and the second pressure connector 2.2. Simultaneously, the internal contours of the first guide hole 3.11 and the second guide hole 3.21 are adapted to the external shapes of the first pressure connector 2.1 and the second pressure connector 2.2, respectively. The first pressure connector 2.1 and the second pressure connector 2.2 can slide within the first guide hole 3.21 and the second guide hole 3.21, respectively. The first crimp connector 2.1 includes a first crimp head 2.11 and a second crimp head 2.12. The position of the first crimp head 2.1 corresponds to the position of the second crimp interface 1.2, and the position of the second crimp head 2.1 corresponds to the position of the first crimp interface 1.1. The second crimp connector 2.2 includes a third crimp head 2.21. The position of the third crimp head 2.21 corresponds to the position of the second crimp interface 1.2, that is, the position of the first crimp head 2.11 corresponds to the position of the third crimp head 2.21. An additional fourth crimp head 2.3 is slidably connected in the through hole 1.3 of the base 1. The position of the fourth crimp head 2.3 corresponds to the position of the first crimp interface 1.1.

[0040] It is understood that the first crimp head 2.11, the second crimp head 2.12, and the third crimp head 2.21 are crimp head structures located on the side of the base 1, while the fourth crimp head 2.3 is a crimp head structure independent of the first crimp head 2.1 and the second crimp head 2.2. The fourth crimp head 2.3 is located inside the through hole 1.3 of the base 1. The first crimp head 2.1, the second crimp head 2.2, and the fourth crimp head 2.3 move in the same direction and move synchronously. Among them, the first crimp head 2.11 and the second crimp head 2.12 are used to squeeze the wire groove at the tail of the RJ45 connector, so that the outer sheath of the network cable is tightened and fixed. The third crimp head 2.21 and the fourth crimp head 2.3 are used for the crimping operation of the RJ45 connector, so that an effective connection (electrical connection) is formed between the network cable and the RJ45 connector.

[0041] Furthermore, such as Figures 4 to 6As shown, the fourth pressure head 2.3 is located between the first pressure head 2.1 and the second pressure head 2.2. The fourth pressure head 2.3, the first pressure head 2.1, and the second pressure head 2.2 are fixedly connected together by the first guide shaft 5.1, thus enabling the first pressure head 2.1, the second pressure head 2.2, and the fourth pressure head 2.3 to move synchronously in the same direction. A connecting piece 6 is also provided between the first pressure head 2.1 and the second pressure head 2.2. The first pressure head 2.1, the second pressure head 2.1, and the connecting piece 6 are connected together by the second guide shaft 5.2, thus enabling the connecting piece 6, the first pressure head 2.1, and the second pressure head 2.2 to move synchronously. One end of the connecting piece 6 is connected to the first pressure head 2.1 and the second pressure head 2.2 via the second guide shaft 5.2, while the other end is hinged to the drive unit 4. In other words, when the drive unit 4 is activated, it can drive the connector 6 to move, which in turn drives the first crimping head 2.1, the second crimping head 2.2 and the fourth crimping head 2.3 to move, thereby realizing the operation of making crystal heads.

[0042] like Figure 3 and Figure 4 As shown, the drive unit 4 has an overall L-shaped structure. The upper side of the drive unit 4 is the force-applying part 4.1, and the lower side of the drive unit 4 is the hook part 4.2. The hook part 4.2 is rotatably connected to the connector 6 on the side facing the base 1, and is rotatably connected to the guide plate on the side away from the base 1. In other words, the drive unit 4 can rotate relative to the guide plates on both sides of the base 1, which in turn causes the hook part 4.2 to deflect, thereby driving the connector 6 to move, and finally realizing the movement of the pressure head assembly 2 on the base 1. Furthermore, a pressure knife 7.1 structure is provided between the force application part 4.1 and the hook part 4.2 of the drive part 4. A pressure knife part is provided on the first guide plate 3.1 and corresponding to the position of the pressure knife 7.1 structure. A pressure knife plate 7.2 is provided on the pressure knife part. The length of the pressure knife plate 7.2 is less than the length of the pressure knife 7.1. Both the pressure knife 7.1 and the pressure knife plate 7.2 are arranged at an angle. When the drive part 4 and the base 1 are closed, the pressure knife 7.1 can be made to fit against the pressure knife plate 7.2, thereby realizing the wire cutting operation of the network cable. Since the length of the pressure knife 7.1 is greater than the length of the pressure knife plate 7.2, a stripping groove 7.3 is provided on the pressure knife part and on the outside of the pressure knife plate 7.2. The stripping groove 7.3 is a groove structure recessed on the pressure knife part. When the pressure knife 7.1 and the pressure knife plate 7.2 are in contact, an arc-shaped hole structure can be formed between the pressure knife 7.1 and the stripping groove 7.3. When the network wire is placed in the stripping groove 7.3, the pressure knife 7.1 will only cut the outer sheath of the network wire, thereby realizing the stripping operation of the insulation of the network wire.

[0043] It should be noted that the first guide shaft 5.1 is located within the first guide groove 1.4 of the base 1, and the second guide shaft 5.2 is located within the second guide groove 1.5 of the base 1. The first guide groove 1.4 includes a horizontal groove and a vertical groove. The vertical groove accommodates the vertically placed fourth pressure head 2.3, which slides within the vertical groove. The horizontal groove accommodates the first guide shaft 5.1, which moves within the horizontal groove. The connecting member 6 includes two oblong plate structures, spaced apart. One end of each oblong plate is connected to the second guide shaft 5.2, and the other end is hinged to the drive unit 4. The position of the second guide groove 1.5 corresponds to the vertical groove in the first guide groove 1.4. The second guide shaft 5.2, located in the middle of the two oblong plate structures, is located within the second guide groove 1.5. Thus, the first pressure head 2.1, the second pressure head 2.2, and the fourth pressure head 2.3 are fixed to the base 1, forming a stable connection. Furthermore, since the first crimp connector 2.1, the second crimp connector 2.2, and the fourth crimp connector 2.3 are all thin-plate structures, during the manufacturing process of the crystal head, the forces on the first crimp connector 2.1, the second crimp connector 2.2, and the fourth crimp connector 2.2 are all perpendicular to the thickness direction of the thin plate. This can easily cause misalignment between the crimp connectors, with the misalignment direction only towards the outer sides of the substrate 1, which can easily lead to a decrease in the quality of the crystal head manufacturing and result in non-compliance. Therefore, using an independent fourth crimp connector 2.3 positioned between the first crimp connector 2.1 and the second crimp connector 2.2 can significantly improve the stability of the three components. At the same time, the first crimp connector 2.1 and the second crimp connector 2.2 are connected by two shafts, the first guide shaft 5.1 and the second guide shaft 5.2, which greatly improves the connection strength and structural stability between the first crimp connector 2.1 and the second crimp connector 2.2, making it less prone to the aforementioned misalignment, thereby ensuring the quality of the crystal head manufacturing and improving the pass rate.

[0044] Below the base assembly and above the drive unit 4, a housing structure is provided. Specifically, the housing below the base assembly is the first housing 8.1, and the housing above the drive unit 4 is the second housing 8.2. The first housing 8.1 is snapped onto the outside of the first guide plate 3.1 and the second guide plate 3.2 using a snap-fit ​​method, and the second housing 8.2 is snapped onto the top of the drive unit 4 using a snap-fit ​​method.
