Description

TECHNICAL FIELD

[0001] The present invention relates to a crimping tool for network jacks, and in particular, to a crimping tool that can be used for both 90° jacks and 180° jacks by switching a switching block that cooperates with a support base. BACKGROUND ART

[0002] Network connectors (also called network jacks or network modules) primarily come in two designs: 90° and 180°. The "degree" here refers to the angle at which the network cable is inserted into the jack. A 90° insertion means the network cable connects to the top of the jack, forming a 90-degree angle, while a 180° insertion means the network cable connects straight to the back of the jack. Both angles are suitable for various installations. In server rooms with multiple jacks in empty slots, 180° jacks are recommended because they are quicker and more convenient to install. When jacks are connected to external outlet boxes, 90° jacks are usually more convenient. Therefore, 90° jacks are suitable for indoor use, while 180° jacks can be used in both server rooms and buildings. Regarding high-speed crimping tools applied to connectors, current crimping tools can electrically connect connectors to wires at very high speeds and can also remove excess core wires (i.e., conductors, network cables, and audio cables each have 8 and 4 core wires respectively), without requiring changes to the specifications of existing connectors or wires. However, 90° and 180° network jacks are different types and are suited to different cutting blade processes and wire bonding bases of different sizes and shapes (i.e., IDC holders / piercing type terminal holders), so the blade holders of the crimping tool cannot be shared between the two types of jacks. Therefore, it is necessary to decide which corresponding cutter head to attach to the crimping tool according to the type of jack before it leaves the factory. Currently, there are 2-in-1 crimping devices for communication connectors that can crimp and cut two types of communication connectors with two different cutter heads, but changing the cutter head in the work area is very inconvenient.

[0003] There is also another crimping hand tool that allows for the exchange of various crimping heads (including crimping and cutting pieces, blade holders, and cutter heads), and allows switching between 90° and 180° jack operation by rotating a housing holder for jacks with two different housing areas. The main advantage of this tool is that it uses a single housing holder with multiple housing areas to accommodate 90° and 180° jacks. However, switching to a different jack requires changing the blade holder accordingly, which is inconvenient. Furthermore, to switch between 90° and 180° jacks, the housing holder is pivoted along a lower rotation axis perpendicular to the horizontal body of the tool. During crimping, the blade holder applies a horizontal crimping thrust to the jack, but since only the rotation axis below the direction of the force is biased towards the jack, if the rotation axis and the blade holder are not on the same horizontal plane, the thrust can easily cause it to tip over.

[0004] Currently, there are no commercially available crimping tools that allow 90° jacks and 180° jacks to share the same blade holder. This is because even slight differences in the external dimensions of the jacks' wire bonding bases require the cutter head to be re-customized. In other words, one jack can only fit one cutter head. [Overview of the project] [Problems that the invention aims to solve]

[0005] Therefore, in view of the drawbacks of conventional crimping tools, such as the inconvenience of needing to replace the cutter head, the tendency to malfunction due to rotation to switch the operating jack, and the clearly insufficient strength of the switching coupling seat, the applicant developed the present invention to overcome the shortcomings of the prior art. The description of the present invention is as follows. [Means for solving the problem]

[0006] The main object of the present invention is to provide a new crimping tool that improves upon the problems of conventional crimping tools, which are inconvenient due to the need to replace the cutter head, prone to failure due to rotation to switch the operating jack, and clearly lacking in strength of the switching coupling seat. One object of the present invention is to provide a crimping tool. The crimping tool includes a tool body, a blade holder provided on the tool body, a support base provided on the tool body having a jack biasing section and a first housing area for housing a 180° jack, and a switching block having a second housing area, which is movably connected to the support base and cooperates with the support base to house a 90° jack in the first housing area and the second housing area, wherein the jack biasing section withstands the force exerted by the blade holder when the blade holder is used to crimp a wire to the 180° jack.

[0007] Another object of the present invention is to provide a crimping tool. The crimping tool comprises a tool body, a workpiece provided on the tool body for performing wire crimping and cutting operations with either a 90° jack or a 180° jack, a first work area provided on the tool body for housing the 180° jack within the first work area, and a workpiece holder that, together with the tool body, forms a second work area for housing the 90° jack within the second work area, wherein when the workpiece is working with the 90° jack, the workpiece holder is located within the tool body.

[0008] Another object of the present invention is to provide a crimping tool. The crimping tool comprises a tool body and a workpiece provided on the tool body to perform wire crimping and cutting operations with either a 90° jack or a 180° jack, wherein when the workpiece performs the wire crimping and cutting operations, the workpiece moves in a first direction; a first working area provided on the tool body to accommodate the 180° jack within the first working area; and a workpiece holder having a rotating shaft connecting the workpiece holder to the tool body, which together with the tool body forms a second working area and accommodates the 90° jack within the second working area, wherein the rotating shaft has an axial direction, and both the axial direction and the first direction extend horizontally.

[0010] When reading the following detailed description, refer to all the figures of the present invention. All the figures of the present invention illustrate different embodiments of the invention by example and help those skilled in the art to understand how to carry out the invention. These embodiments provide sufficient embodiments to demonstrate the spirit of the invention, each embodiment is non-contradictory to the others, and new embodiments can be carried out through any combination thereof. That is, the present invention is not limited to the embodiments disclosed herein.

[0011] To enable crimping and cutting operations for two types of jacks using only one cutter head, the dimensions of the wire bonding bases for 90° and 180° jacks, particularly the dimensions of the areas where wires are cut and crimped, must be designed to be consistent. The crimping tool for network jacks proposed by this invention can complete the cutting and crimping of two types of jacks, 90° and 180° jacks, with only one cutter head without changing the cutter head. Referring together to Figures 1 to 6, the crimping tool 10 for network jacks is shown. The crimping tool 10 consists of a tool body 11 (usually made of iron), a support base 12, a switching block 13, etc. The tool body 11 has a first shaft hole 141. The support base 12 is mounted on the tool body 11 and, as shown in Figure 2, includes a first housing area 21, a second shaft hole 142, a block biasing section 22, and a 180° jack biasing section 23. The switching block 13 comprises a second housing area 242, a third shaft hole 143, and a rotating shaft 15. The switching block 13 is rotatably connected to the support base 12 and the tool body 11 by the rotating shaft 15, which passes through the first shaft hole 141, the second shaft hole 142, and the third shaft hole 143. The rotating shaft 15 changes the switching block 13 between a first position shown in Figure 3 and a second position shown in Figure 4. The switching block 13 can be rotated 90° or 180° relative to the support base 12 by the rotating shaft 15. When the switching block 13 is in the first position, it is located within a portion of the first housing area 21, and the block biasing portion 22 abuts against the switching block 13, so that the remaining portion of the first housing area 21 and the second housing area 242 of the switching block 13 form a 90° jack housing space 32 for housing a 90° jack 31, as shown in Figure 3. The second housing area 242 of the switching block 13 includes a 90° jack biasing portion 26 for holding a 90° jack. When the switching block 13 is in the first position, the first housing area 21 and the second housing area 242 overlap and are configured together to receive a 90° jack for crimping and cutting operations.When the switching block 13 is in the second position, it is located partially or completely outside the first housing area 21, and the space between the first housing area 21 of the support base 12 and the 180° jack biasing portion 23 is configured to receive and hold the 180° jack 41, forming a 180° jack receiving space 42 for housing the 180° jack 41, as shown in Figure 4. Since the first position is within the first housing area 21 of the support base 12, when the switching block 13 moves to the second position, the switching block 13 is no longer within the first housing area 21 of the support base 12. The wire bonding base 33 of the 90° jack 31 and the wire bonding base 43 of the 180° jack 41 are designed so that the dimensions of the portion where the wire is cut and crimped match.

[0012] In the above embodiment, the crimping tool 10 further comprises a horizontal rod 16, the tool body 11 has a first rod hole 171, and the support base 12 has a second rod hole 172. The support base 12 is fixed to the tool body 11 by the horizontal rod 16 passing through the first rod hole 171 and the second rod hole 172. The crimping tool 10 further comprises a blade holder 18 provided on the tool body 11 for cutting and crimping the core wires of the 90° jack 31 and the 180° jack 41. When the blade holder 18 cuts and crimps the core wires in the 90° jack 31, the force from the blade holder 18 is received by the 90° jack biasing section 26.

[0013] Referring to Figure 5, the switching block 13 has a first fastener 51 and a second fastener 132 for fixing the switching block 13. The support base 12 has a third fastener 53 and a fourth fastener 54. When a 90° jack is crimped, the third fastener 53 is used to connect (e.g., lock or engage) to the first fastener 51, and when a 180° jack is crimped, the fourth fastener 54 is used to connect (e.g., lock or engage) to the second fastener 132. As shown in Figure 6, the switching block 13 has a first positioning biaser 521 and a second positioning biaser 62. The support base 12 has a third positioning biaser 63 and a fourth positioning biaser 64. When crimping a 90° jack, the third positioning biaser 63 contacts the first positioning biaser 521. When crimping a 180° jack, the fourth positioning biaser contacts the second positioning biaser 62.

[0014] The support base 12 has one or more protective members 27 (e.g., protective covers) extending from the support base 12. When the switching block 13 is in the second position, the protective members 27 are positioned outside the switching block 13 to protect the switching block 13. The crimping tool 10 is slidably mounted on the tool body 11 and includes a slider 19 that constitutes the blade holder 18. The slider 19 has an extension arm 191, and the support base 12 has a guide groove 121 that guides the movement of the extension arm 191. The blade holder 18 is fitted with an adjustment screw 181 for adjusting the crimping process of the blade holder 18. The crimping tool 10 includes a pressing member 111 provided on the tool body 11 and used to press the blade holder 18. The assembled crimping tool 10 is shown in Figure 7, where the horizontal plane in Figure 7 refers to the plane formed by the X and Z axes.

[0015] The present invention further provides a crimping tool 10 comprising a tool body 11, a blade holder 18, a support base 12, and a switching block 13. The blade holder 18 is provided on the tool body 11. The support base 12 is provided on the tool body 11 and has a jack biasing section (such as a 180° jack biasing section 23) and a first housing area 21 to accommodate a 180° jack. The switching block 13, having a second housing area 242, is movably connected to the support base 12 and cooperates with the support base 12 to accommodate a 90° jack 31 in the first housing area 21 and the second housing area 242. When crimping a wire to a 180° jack 41 using the blade holder 18, the jack biasing section withstands the force applied by the blade holder 18.

[0016] Compared to the above embodiment, the crimping tool 10 can be configured without a block biasing portion 22 (not shown) on the support base 12. In this case, the tool body 10 has a first shaft hole 141, the support base 12 has a second shaft hole 142, and the switching block 13 has a rotating shaft 15 and a second housing area 242. The switching block 13 is rotatably connected to the support base 12 and the tool body 11 by a rotating shaft 15 that passes through the first shaft hole 141 and the second shaft hole 142, and the rotating shaft 15 supports the force applied by the blade holder 18. When the switching block 13 is located in part of the first housing area 21, the 90° jack 31 can be housed in the space formed by the remaining part of the first housing area 21 and the second housing area 242 of the switching block 13, allowing the blade holder 18 to crimp the wire to the 90° jack 31. During the crimping process, the force exerted by the blade holder 18 is borne solely by the rotating shaft 15, and not together with the block biasing unit 22, and this embodiment is also feasible.

[0017] Compared to the above embodiment, the crimping tool 10 can also be designed without a rotating shaft 15 (not shown). In this case, the switching block 13 can be removed directly from the support base 12. The switching block 13 has a second receiving region 242, the support base 12 has second shaft holes 142 on both sides, and the crimping tool 10 further includes a first screw and a second screw (not shown) on the opposite side of the first screw. The support base 12 passes through the second shaft holes 142 on both sides for fixing it to the tool body 11. When the switching block 13 is in the first position, the first receiving region 21 and the second receiving region 242 are configured to receive a 90° jack for crimping and cutting operations by the blade holder 18. When the switching block 13 moves to the second position, the first receiving region 21 and the jack biasing region are configured to receive and hold a 180° jack for crimping and cutting operations by the blade holder 18, respectively. In this embodiment, the first position is within the first receiving region 21 of the support base 12, and the second position is not within the first receiving region 21 of the support base 12. In one embodiment, the crimping tool 10 consists of a block biasing section 22 integrally formed with the support base 12. In one embodiment, the switching block 13, the jack biasing section, the block biasing section 22, and the blade holder 18 are on the same horizontal plane, and when the wire is crimped to the 90° jack 31 using the blade holder 18, the switching block 13 and the block biasing section 22 support the force applied by the blade holder 18.

[0018] In one embodiment, the crimping tool has a tool body 12 (not shown) integrally formed with a support base 11. In this case, the tool body 11 and the support base 12 can be integrally formed from plastic without a rotating shaft and without using first and second screws to fix the support base 12 to the tool body 11, and can withstand the force applied by the blade holder 18. In another embodiment, the tool body 11 and the support base 12 are not integrally formed. Instead, the support base 12 has connecting parts 122 on both sides for connecting to base biasing parts 112 on both sides of the tool body 11, eliminating the need for a rotating shaft 15 and being able to withstand the force applied by the blade holder 18. In one embodiment, the switching block 13, which pivots around the horizontal axis in the figure, is changed from its original horizontal position to a vertical lifting structure of the switching block within the support base. In one embodiment, the switching block 13 is divided into a left block and a right block, and the left block and the right block can be positioned so that they are far apart or close to each other in the horizontal direction (the direction perpendicular to the direction in which the blade holder is pushed forward). In actual applications, the switching block 13 may be realized by the structure described above, but is not limited thereto.

[0019] The present invention further provides a crimping tool 10 comprising a tool body 11, a workpiece (e.g., a blade holder 18), a first working region (e.g., a first receiving region 21), and a workpiece retainer (e.g., a switching block 13). The workpiece is provided on the tool body 11 to perform wire crimping and cutting operations with either a 90° jack or a 180° jack. The first working region is disposed on the tool body 11 and accommodates a 180° jack 41 within the first working region. The workpiece retainer has a rotating shaft 15 that connects the workpiece retainer to the tool body 11, the workpiece retainer forms a second working region (e.g., a second receiving region 242) together with the tool body 11, and accommodates a 90° jack 31 inside the second working region. When the workpiece operates with the 90° jack 31, the workpiece retainer is disposed inside the tool body 11. When the workpiece operates with the 180° jack 41, at least a portion of the workpiece retainer is located outside the tool body 11.

[0020] The present invention further provides a crimping tool 10 comprising a tool body 11, a workpiece (e.g., a blade holder 18), a first working region (e.g., a first receiving region 21), and a workpiece retainer (e.g., a switching block 13). The workpiece is provided on the tool body 11 to perform wire crimping and cutting operations with either a 90° jack or a 180° jack. When the workpiece performs the wire crimping and cutting operations, the workpiece moves in a first direction FD, as shown in Figure 7. The first working region is disposed on the tool body 11 and accommodates a 180° jack 41 within the first working region. The workpiece retainer has a rotating shaft 15 that connects the workpiece retainer to the tool body 11, and is disposed on the tool body 11. The workpiece retainer forms a second working region (e.g., a second receiving region 242) together with the tool body 11, and accommodates a 90° jack 31 inside the second working region. The rotating shaft 15 has an axial direction AD (see Figure 7), and both the axial direction AD and the first direction FD extend in the horizontal direction. The axial direction AD is perpendicular to the first direction FD.

[0021] The present invention further provides a crimping tool 10 comprising a tool body 11, a workpiece (e.g., a blade holder 18), a first working region (e.g., a first receiving region 21), and a workpiece holder (e.g., a switching block 13). The workpiece is provided on the tool body 11 so as to perform wire crimping and cutting operations with either a 90° jack or a 180° jack. The first working region is provided on the tool body and accommodates a 180° jack 41 within the first working region. The workpiece holder forms a second working region (e.g., a second receiving region 242) together with the tool body 11, and accommodates a 90° jack 31 inside the second working region. The first working region is formed independently of the workpiece holder.

[0022] The present invention further provides a crimping tool 10 comprising a tool body 11, a workpiece (e.g., a blade holder 18), a first working region (e.g., a first receiving region 21), and a workpiece holder (e.g., a switching block 13).

The workpiece holder forms a second working region (e.g., a second receiving region 242) together with the tool body 11, and accommodates a 90° jack 31 inside the second working region. The first working region is formed independently of the workpiece holder. When the workpiece performs wire crimping and cutting operations with the 180° jack 41, the workpiece holder is located outside the tool body 11, and the 180° jack in the first working region does not come into contact with the workpiece holder.

[0023] In one embodiment, the first and second working areas are formed within the tool body. In one embodiment, the axial direction is perpendicular to the first direction. In one embodiment, the 90° jack in the second working area is fixed by the workpiece holder, and the 180° jack in the first working area does not come into contact with the workpiece holder.
