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° and 180° jacks by switching a switching block that cooperates with a support base. [Background technology]

[0002] For network connectors (also called network jacks, network modules, etc.), the two main designs of jacks are 90 degrees (90°) and 180 degrees (180°). The "degree" here refers to the angle at which the network cable is driven into the jack. A 90° drive-in means that the network cable is connected to the top of the jack, forming a 90-degree angle, while a 180° drive-in means that the network cable is connected straight into the back of the jack. Both angles are suitable for different installations. If you are installing in a server room and there are multiple jacks in a blank drive-in, a 180° jack is recommended because it is quicker and more convenient to install. If the jack is connected to an external outlet box, it is usually more convenient to use a 90° jack. Therefore, a 90° jack is suitable for use inside the building, and a 180° jack can be used in both the server room and the building. Regarding high-speed crimping tools applied to connectors, current crimping tools can electrically connect connectors to wires at a very high speed and also remove excess cores (i.e., conductors, network cables and voice cables have 8 cores and 4 cores, respectively), without the need to change the specifications of existing connectors or wires. However, since 90° and 180° network jacks are different types and suitable for different cutting blade processes and different sizes and shapes of wire bonding bases (i.e., IDC holders / piercing type terminal holders), the blade holder cannot share the terminals of the crimping tool with the two types of jacks. Therefore, it is necessary to determine which corresponding cutter head to install on the crimping tool according to the type of jack before shipping from the factory. Currently, there is a 2-in-1 crimping machine for communication connectors, which is a crimping machine that can crimp and cut two types of communication connectors with two different cutter heads, but it is very inconvenient to change the cutter head at the work site.

[0003] There are also other crimping hand tools, which can be used to change between different crimping heads (also referred to as crimping and cutting pieces, blade holders, cutter heads, etc.) and rotate the receiving holder for the jack with two different receiving areas to switch between 90° and 180° jack operation. The main advantage of this tool is that it uses a single receiving holder with multiple receiving areas to accommodate 90° and 180° jacks. However, when switching between different jacks, the blade holder needs to be changed accordingly, which is inconvenient. Furthermore, to switch between 90° and 180° jacks, the receiving holder is pivoted along a lower rotation axis that is perpendicular to the horizontal body of the tool. During crimping, the blade holder applies a horizontal crimping thrust to the jack, but only the rotation axis below the force direction is subject to the jack's force, so if the rotation axis and the blade holder are not on the same horizontal plane, the thrust may easily cause the jack to tip over.

[0004] Currently, there are no commercially available crimping tools that allow 90° and 180° jacks to share the same blade holder, because the slight differences in the external dimensions of the wirebond base of the jacks require the cutterhead to be re-customized, meaning that one jack can only fit one cutterhead. Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, in view of the drawbacks of the conventional crimping tool, such as the need to replace the cutter head, the fact that the operating jack is easily broken due to rotation for switching, and the obvious lack of strength of the switching coupling seat, the applicant has developed the present invention in order to overcome the drawbacks of the prior art. The present invention is described as follows. [Means for solving the problem]

[0006] The main object of the present invention is to provide a new crimping tool that overcomes the problems of the prior art crimping tool, such as the need to replace the cutter head, the tendency to break when rotating to switch the operating jack, and the obvious lack of strength of the switching joint seat. One object of the present invention is to provide a crimping tool, which includes a tool body, a blade holder provided on the tool body, a support base provided on the tool body, having a jack biasing part and a first receiving area for receiving a 180° jack, and a switching block having a second receiving area, the switching block being movably connected to the support base and cooperating with the support base to receive a 90° jack in the first receiving area and the second receiving area, and the jack biasing part 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 comprising a tool body, a workpiece mounted on said tool body for performing wire crimping and cutting operations with either a 90° jack or a 180° jack, a first working area mounted on said tool body for accommodating said 180° jack within said first working area, and a workpiece holder forming said second working area together with said tool body for accommodating said 90° jack within said second working area, said workpiece holder being located within said tool body when said workpiece operates with said 90° jack.

[0010] When reading the following detailed description, please refer to all figures of the present invention. All figures of the present invention show different embodiments of the present invention by illustrating examples, and help those skilled in the art understand how to implement the present invention. This example provides sufficient embodiments to demonstrate the spirit of the present invention, and each embodiment is not inconsistent with other embodiments, and new embodiments can be implemented through any combination thereof. That is, the present invention is not limited to the embodiments disclosed in this specification.

[0011] In order to perform the crimping and cutting operations of the two types of jacks with only one cutter head, the dimensions of the wire bonding bases of the 90° jack and the 180° jack, especially the dimensions of the portions where the wires are cut and crimped, need to be designed to be consistent. The network jack crimping tool proposed by the present invention can complete the cutting and crimping of the two types of jacks, the 90° jack and the 180° jack, with only one cutter head without changing the cutter head. With reference to Figures 1 to 6, a network jack crimping tool 10 is shown. The crimping tool 10 is composed 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 provided on the tool body 11, and includes a first accommodation area 21, a second shaft hole 142, a block biasing portion 22, and a 180° jack biasing portion 23, as shown in Figure 2. The switching block 13 includes 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 passing 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 FIG. 3 and a second position shown in FIG. 4. The switching block 13 can rotate 90° or 180° relative to the support base 12 by the rotating shaft 15. When the switching block 13 is in the first position, the switching block 13 is located within a part of the first housing area 21, and the block biasing portion 22 abuts against the switching block 13, so that the remaining part of the first housing area 21 of the switching block 13 and the second housing area 242 form a 90° jack housing space 32 for housing the 90° jack 31, as shown in FIG. 3. The second housing area 242 of the switching block 13 includes a 90° jack biasing portion 26 for holding the 90° jack. When the transfer block 13 is in the first position, the first receiving area 21 and the second receiving area 242 overlap and are configured together to receive a 90° jack for a crimping and cutting operation.When the switching block 13 is in the second position, the switching block 13 is located partially or completely outside the first accommodation area 21, and is configured to receive and hold the 180° jack 41 between the first accommodation area 21 and the 180° jack biasing portion 23 of the support base 12, and a 180° jack receiving space 42 for receiving the 180° jack 41 is formed as shown in Fig. 4. Since the first position is within the first accommodation area 21 of the support base 12, when the switching block 13 moves to the second position, the switching block 13 is not present within the first accommodation 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 portions where the wires are cut and crimped match.

[0012] In the above embodiment, the crimping tool 10 further includes 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 includes a blade holder 18 provided on the tool body 11 to cut and crimp the core wires of the 90° jack 31 and the 180° jack 41. When the blade holder 18 cuts and crimps the core wire in the 90° jack 31, the force applied by the blade holder 18 is received by the 90° jack biasing portion 26.

[0013] Referring to FIG. 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 the 90° jack is crimped, the third fastener 53 is used to connect (e.g., lock or engage) with the first fastener 51, and when the 180° jack is crimped, the fourth fastener 54 is used to connect (e.g., lock or engage) with the second fastener 132. As shown in FIG. 6, the switching block 13 has a first positioning biasing portion 521 and a second positioning biasing portion 62. The support base 12 has a third positioning biasing portion 63 and a fourth positioning biasing portion 64. When the 90° jack is crimped, the third positioning biasing portion 63 abuts against the first positioning biasing portion 521. When the 180° jack is crimped, the fourth positioning biasing portion abuts against the second positioning biasing portion 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 disposed outside the switching block 13 to protect the switching block 13. The crimping tool 10 includes a slider 19 slidably attached to the tool body 11 and constituting a blade holder 18 thereon. The slider 19 has an extension arm 191, and the support base 12 has a guide groove 121 for guiding the movement of the extension arm 191. The blade holder 18 is attached 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 as shown in FIG. 7, and the horizontal plane in FIG. 7 refers to the plane formed by the X-axis and the Z-axis.

[0015] The present invention further provides a crimping tool 10, which includes a tool body 11, a blade holder 18, a support base 12, and a changeover 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 portion (such as the 180° jack biasing portion 23) and a first receiving area 21 to receive the 180° jack. The changeover block 13, which has a second receiving area 242, is movably connected to the support base 12 and cooperates with the support base 12 to receive the 90° jack 31 in the first receiving area 21 and the second receiving area 242. When the blade holder 18 is used to crimp a wire to the 180° jack 41, the jack biasing portion withstands the force applied by the blade holder 18.

[0016] In the crimping tool 10, the support base 12 may not be provided with the block biasing portion 22 (not shown) as compared with the above embodiment. 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 rotation shaft 15 and a second accommodation area 242. The switching block 13 is rotatably connected to the support base 12 and the tool body 11 by the rotation shaft 15 that passes through the first shaft hole 141 and the second shaft hole 142, and the rotation shaft 15 supports the force applied by the blade holder 18. When the switching block 13 is located in a part of the first accommodation area 21, the 90° jack 31 can be accommodated in the space formed by the remaining part of the first accommodation area 21 of the switching block 13 and the second accommodation area 242, 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 only by the rotating shaft 15 and not together with the block biasing part 22; this embodiment is also feasible.

[0017] Compared with 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 taken out directly from the support base 12. The switching block 13 has a second receiving area 242, the support base 12 has a second axial hole 142 on both sides, and the crimping tool 10 further includes a first screw and a second screw (not shown) opposite to the first screw. Through the second axial hole 142 on both sides for fixing the support base 12 to the tool body 11. When the switching block 13 is in the first position, the first receiving area 21 and the second receiving area 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 area 21 and the jack biasing part are respectively configured to receive and hold a 180° jack for crimping and cutting operations by the blade holder 18. In this embodiment, the first position is within the first receiving area 21 of the support base 12, and the second position is not within the first receiving area 21 of the support base 12. In one embodiment, the crimping tool 10 comprises a block bias 22 integrally formed with the support base 12. In one embodiment, the changeover block 13, jack bias, block bias 22 and blade holder 18 are in the same horizontal plane, and the changeover block 13 and block bias 22 support the force applied by the blade holder 18 when the blade holder 18 is used to crimp a wire into the 90° jack 31.

[0018] In one embodiment, the crimping tool has a tool body 12 (not shown) integrally formed with the support base 11. In this case, the tool body 11 and the support base 12 can be integrally formed of plastic without providing a rotation axis and without using a first screw and a second screw to fix the support base 12 to the tool body 11, and can withstand the action force of 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 the base biasing parts 112 on both sides of the tool body 11, respectively, so that the switching block 13, which rotates around the horizontal axis in the figure, is changed from its original horizontal position to a vertical lifting structure of the switching block in 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 are replaced so that they can be separated or close to each other in the horizontal direction (the direction perpendicular to the direction in which the blade holder is pushed forward). In practical application, the switching block 13 can be embodied by the above-mentioned structure, but is not limited thereto.

[0019] The present invention further provides a crimping tool 10 comprising a tool body 11, a workpiece (e.g., blade holder 18), a first working area (e.g., first receiving area 21), and a workpiece holder (e.g., changeover block 13). The workpiece is mounted on the tool body 11 to perform wire crimping and cutting operations at either the 90° jack or the 180° jack. The first working area is mounted on the tool body 11 and receives the 180° jack 41 within the first working area. The workpiece holder has a rotation axis 15 connecting the workpiece holder to the tool body 11, and the workpiece holder forms a second working area (e.g., second receiving area 242) together with the tool body 11 and receives the 90° jack 31 within the second working area. When the workpiece works at the 90° jack 31, the workpiece holder is disposed within the tool body 11. When the workpiece works at the 180° jack 41, at least a portion of the workpiece holder 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., blade holder 18), a first working area (e.g., first receiving area 21), and a workpiece holder (e.g., changeover block 13). The workpiece is mounted on the tool body 11 to perform wire crimping and cutting operations at either the 90° jack or the 180° jack. When the workpiece performs wire crimping and cutting operations, the workpiece moves in a first direction FD, as shown in FIG. 7. The first working area is mounted on the tool body 11 and receives the 180° jack 41 in the first working area. The workpiece holder is mounted on the tool body 11, with a rotation axis 15 connecting the workpiece holder to the tool body 11. The workpiece holder forms a second working area (e.g., second receiving area 242) together with the tool body 11, and receives the 90° jack 31 inside the second working area. The rotation axis 15 has an axial direction AD (see FIG. 7), and both the axial direction AD and the first direction FD extend horizontally. 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., blade holder 18), a first working area (e.g., first receiving area 21), and a workpiece holder (e.g., changeover block 13). The workpiece is provided in the tool body 11 to perform wire crimping and cutting operations with either a 90° jack or a 180° jack. The first working area is provided in the tool body 11 and receives the 180° jack 41 within the first working area. The workpiece holder forms a second working area (e.g., second receiving area 242) together with the tool body 11 and receives the 90° jack 31 within the second working area. The first working area 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., blade holder 18), a first working area (e.g., first receiving area 21), and a workpiece holder (e.g., changeover block 13). The workpiece is provided in the tool body 11 to perform wire crimping and cutting operations with either the 90° jack or the 180° jack.

The workpiece holder forms a second working area (e.g., second receiving area 242) together with the tool body 11 and receives the 90° jack 31 inside the second working area. The first working area 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 area does not contact the workpiece holder.

[0023] In one embodiment, the first working area and the second working area 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 secured by the workpiece holder and the 180° jack in the first working area does not contact the workpiece holder. In one embodiment, the workpiece holder is moved by the axis of rotation between a first position within the tool body and a second position outside the first working area, such that when the workpiece holder is in the first position, the second working area is formed and when the workpiece holder is in the second position, the first working area is formed.

[0024] In view of the above, the present invention provides a novel structure crimping tool, which can easily switch between 90° jack receiving space and 180° jack receiving space by a switching block movably connected to the support base and cooperating with the support base.
