Description

Technical Field

[0001] This invention relates to the field of mechanical switching and transmission technology, and in particular to a switching mechanism for network cable clamps. Background Technology

[0002] In the process of crimping RJ45 connectors with a network cable crimping tool, different types of connectors, such as shielded and unshielded ones, need to be crimped. The crimping processes differ between these types, so it's necessary to switch between two different working modes to suit the specific requirements.

[0003] In actual construction, it is often necessary to frequently switch between crimping modes. Existing technologies have the following technical defects: Inconvenient operation mode switching: Existing switchable network cable crimpers and similar tools usually require additional auxiliary tools such as screwdrivers and pliers to adjust when switching crimping modes. The operation process is cumbersome, reduces the efficiency of construction work, and increases the workload of operators.

[0004] Therefore, the industry urgently needs a switching mechanism for network cable clamps that can quickly switch operating modes without the aid of auxiliary tools. Summary of the Invention

[0005] The purpose of this invention is to provide a switching mechanism for network cable clamps to solve the above-mentioned technical defects in the prior art.

[0006] The core of the switching mechanism for network cable clamps provided by this invention consists of a switching adjustment assembly 11 and a switchable actuator 13. The switching adjustment assembly 11 includes a rotating component 111, a cam 113, and a first elastic component 114. The rotating component 111 is rotatably mounted on a mounting base 2, and the cam 113 is drive-connected to the rotating component 111. The mounting base 2 has mutually compatible crimping grooves and switching grooves, arranged perpendicularly to each other. The switchable actuator 13 and the mating actuator 12 are slidably assembled in the crimping groove, and the first elastic component 114 is slidably assembled in the switching groove. The first elastic component 114 has an elongated hole 1141, and a connecting pin 16 is fixedly connected to the transmission component 14. The connecting pin 16 is slidably engaged in the elongated hole 1141 and fixedly connected to the transmission component 14 and the switchable actuator 13, making the three components integrated. The rotating component 111 drives the cam 113 to rotate, and the cam 113 drives the first elastic component 114 to move within the switching groove. This, in turn, through the engagement of the connecting pin 16 and the elongated hole 1141, drives the switchable actuator 13 to move axially along the connecting component 15, achieving synchronous or asynchronous movement between the switchable actuator 13 and the mating actuator 12. The transmission component 14 is equipped with a guide and limiting structure 141, and the mating actuator 12 is equipped with a connecting component 15, forming a guiding and limiting engagement. When the switchable actuator 13 is in the first position, the guide and limiting structure 141 and the connecting component 15 form a stable locking connection, ensuring synchronous transmission between the two components. When the switchable actuator 13 moves to the second position, the switchable actuator 13 and the mating actuator 12 are axially misaligned, releasing the locking connection. The switchable actuator 13 exits the pressing operation mode, and only the mating actuator 12 participates in the pressing. The cam 113 uses a dedicated contour curve to achieve stable self-locking in both working positions.

[0007] As a preferred embodiment, the guide and limiting structure 141 can be an oblong hole, and the connecting member 15 can be a pin, which is movably inserted into the oblong hole to form a fit. The connecting pin 16 can be a large-headed pin with a head size larger than the rod size, and the connecting pin 16, the transmission member 14, and the switchable actuator 13 can be an integrally cast structure.

[0008] The switching adjustment component 11 can be operated without the aid of auxiliary tools, enabling quick switching between two crimping operation modes. As a further optimization, the switching mechanism can also be integrated with the gripping mechanism 3 to form a network cable clamp, and the mounting base 2 is equipped with crimping grooves, switching grooves, and multiple selectable operation stations.

[0009] Compared with the prior art, the present invention has the following advantages: by switching the adjustment component 11 to drive the switchable actuator 13 to engage or disengage with the mating actuator 12, the crimping modes of different specifications of crystal heads can be quickly switched without the need for auxiliary tools, making the operation convenient.

In this application, unless otherwise expressly specified and limited, the terms "installed," "connected," "joined," "fixed," etc., should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Example 1: Switching Mechanism This embodiment provides a switching mechanism 1 for network cable crimping, focusing on its application in the crimping of RJ45 connectors with network cable crimping.

[0024] In this embodiment, the switchable actuator 13 is a crystal head crimping auxiliary plate, used to assist in crimping the crystal head shell during the crimping process to prevent loosening of the connection. The crystal head crimping teeth are used to complete the crimping and conduction of the metal sheet and the wire core, and their specific structure can adopt conventional designs in the art. The mounting base 2 is provided with a crimping groove and a switching groove. The switchable actuator 13 and the mating actuator 12 are slidably assembled in the crimping groove, and the first elastic member 114 is slidably assembled in the switching groove. The working end of the switchable actuator 13 is movably embedded in the first working station 21. The first elastic member 114 is provided with an elongated hole 1141. A connecting pin 16 is fixedly connected to the transmission member 14. The connecting pin 16 is slidably engaged in the elongated hole 1141 and is fixedly connected to the transmission member 14 and the switchable actuator 13, so that the three are connected as one. The transmission member 14 is provided with a guide limiting structure 141, and the mating actuator 12 is provided with a connecting member 15. The two form a guide and limiting engagement. In this embodiment, the guide limiting structure 141 is an elongated hole, and the connector 15 is a pin.

[0025] like Figure 9 and Figure 10As shown, the assembly relationship of this switching mechanism is as follows: The mounting base 2 has a pressing groove and a switching groove, which are arranged perpendicularly to each other. The mating actuator 12 and the switchable actuator 13 are assembled side-by-side in the pressing groove and can slide along it. The first elastic element 114 is assembled in the switching groove and can slide along it. The transmission element 14 is fixedly connected to the switchable actuator 13, and the guide limiting structure 141 on the transmission element 14 is movably engaged with the connecting element 15 on the mating actuator 12. The connecting pin 16 is fixed to the transmission element 14, its head slidingly engaged in the elongated hole 1141 of the first elastic element 114, and its rod passing through the transmission element 14 and the switchable actuator 13. The rotating element 111 is rotatably mounted on the mounting base 2, and the cam 113 is connected to the rotating element 111, with the outer circumferential surface of the cam 113 abutting against the first elastic element 114.

[0026] During mode switching, rotating component 111 drives cam 113 to rotate, and cam 113 drives first elastic component 114 to move within the switching groove. Through the push-pull engagement of connecting pin 16 and elongated hole 1141, transmission component 14 and switchable actuator 13 move axially along connector 15. During pressing operations, switchable actuator 13 and mating actuator 12 move synchronously along pressing groove. Combined with the guiding function of the groove, smooth switching is ensured while preventing radial and circumferential wobbling of each actuator.

[0027] When crimping a standard RJ45 connector is required, rotating the rotating component 111 drives the switchable actuator 13 to move to the first position. At this time, the switchable actuator 13 and the mating actuator 12 abut side by side, and the connecting component 15 is limited by the guide and limiting structure 141. The two components form a stable engaging connection and move synchronously. The crimping teeth of the RJ45 connector complete the crimping and conduction, and the switchable actuator 13 simultaneously presses the RJ45 connector housing. After the crimping operation is completed, the switchable actuator 13 retracts and resets as the handle opens, and the guide and limiting structure 141 drives the switchable actuator 13 back by hooking the connecting component 15.

[0028] When crimping special-sized RJ45 connectors is required, the rotating component 111 is rotated in the reverse direction, driving the switchable actuator 13 to move to the second position. At this time, the switchable actuator 13 and the mating actuator 12 are axially misaligned, the locking connection is released, and the switchable actuator 13 exits the crimping operation mode, with only the mating actuator 12 participating in the crimping. The switching mechanism 1 in this embodiment can meet the crimping requirements of different-sized RJ45 connectors, with convenient mode switching and precise positioning.

[0029] Example 2: Specific Structure of the Switching Adjustment Component Based on Example 1, this embodiment elaborates in detail on the specific structure and transmission principle of the switching adjustment component 11.

[0030] The rotating component 111 adopts a shuttle-shaped knob structure with a concave anti-slip design on its outer surface. The operator can insert their fingers into this concave structure to transmit rotational force and achieve manual adjustment. The cam 113 is fixedly connected to the rotating component 111 via a rotating shaft to achieve synchronous rotation.

[0031] The first elastic element 114 is an elastic ring plate structure made of 65 manganese spring steel, which has excellent elasticity and wear resistance. In this embodiment, the first elastic element 114 includes a frame body and an internal partition rib; the frame is a square frame structure with a single-sided opening, the outer corners are rounded, and a long through hole 1141 is opened on one side of the frame wall; the partition rib extends inward from a set of opposite frame walls on the inner side of the frame and is suspended, forming a hollow clearance cavity with the inner wall of the frame.

[0032] The connecting pin 16 is a large-headed pin with a head size larger than the rod size. Its head slides within the elongated hole 1141, and the rod passes through the elongated hole 1141 and the transmission member 14 in sequence before being fixed to the switchable actuator 13. The head size of the connecting pin 16 is larger than the width of the elongated hole 1141, so that the first elastic member 114 is pinned to the switchable actuator 13 with a gap by the connecting pin 16.

[0033] The engagement between the connecting pin 16 and the elongated hole 1141 has different functions under different working conditions: during crimping operations, the connecting pin 16 slides along its length within the elongated hole 1141; during switching operations, the first elastic element 114 hooks the connecting pin 16 through the elongated hole 1141, thereby pushing and pulling the switchable actuator 13 to slide relative to the mating actuator 12 along the extension direction of the switching groove. When the cam 113 drives the first elastic element 114 to move, the connecting pin 16, the transmission element 14, and the switchable actuator 13 slide as a whole relative to the mating actuator 12 along the extension direction of the switching groove. The connecting pin 16 is fixedly connected to the transmission element 14 and the switchable actuator 13, and the three can be integrally cast.

[0034] When the rotating component 111 is rotated, the cam 113 rotates synchronously. The outer circumferential surface of the cam 113 presses against the first elastic element 114, causing it to slide within the switching groove. It also hooks the connecting pin 16 through the elongated hole 1141, using elastic force to push and pull the switchable actuator 13 to move precisely along the axial direction of the connecting component 15. The cam 113 adopts a special contour curve structure design with a wide top and a beveled surface. In the two working positions, the elastic force of the first elastic element 114 presses the cam 113 flat and fits, forming a stable self-locking mechanism. This ensures smooth and stable switching action and prevents it from shifting on its own during use.

[0035] Example 3: Switching mechanism integrating gripping mechanism This embodiment further integrates a gripping mechanism 3 based on embodiment 1 or 2.

[0036] Both the fixed grip component 31 and the movable grip component 32 are made of engineering plastic and metal composite structure, and the surface of the metal components is treated with rust prevention and surface beautification. The mounting base 2 is fixedly assembled to the front end of the fixed grip component 31 by a snap ring pin. The base is provided with a crimping slide, a switching slide, and three sets of working stations. The first working station 21 is adapted to the operation of the improved structure of this application, and the second and third working stations are adapted to medium and small crystal heads, respectively.

Any equivalent structural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
