Low-wear moving connector

Abstract

The application discloses a low-wear dynamic connector, which comprises a pair of dynamic contacts, and a spring connected between the pair of dynamic contacts, wherein the spring continuously provides driving force to the pair of dynamic contacts in the direction of rotation, thereby providing clamping force during the contact of the pair of dynamic contacts with a static connector, and characterized in that a dynamic contact position adjusting mechanism is arranged on the dynamic connector, so that the pair of dynamic contacts are in contact with or separated from the static connector only when the pair of dynamic contacts are in the position of plugging or separating from the static connector, thereby shortening the contact process of the pair of dynamic contacts with the static connector and reducing the wear between the pair of dynamic contacts and the static connector.

Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinet technology, specifically relating to a low-wear dynamic connector that can effectively reduce wear during the insertion and separation of dynamic and static connectors in power distribution cabinets, and extend the service life of the connectors. Background Technology

[0002] In modern power distribution networks and engineering construction, withdrawable low-voltage switchgear is widely used in power plants, substations, and other similar applications. Switchgear plays a crucial role in the conversion, distribution, and control of electrical energy for power distribution, motor control, and lighting equipment. This type of switchgear offers advantages such as space saving, reliable operation, convenient installation and maintenance, strong breaking capacity, and multiple outgoing circuits.

[0003] Primary connectors mainly refer to the connectors used in the primary circuits (i.e., main circuits) of a distribution cabinet. Circuit continuity is achieved through the mating of the moving connector and the stationary connector, and circuit disconnection is achieved by separating the moving connector and the stationary connector. Traditionally, stationary connectors are usually vertical busbars or independent connectors, generally with a stationary copper contact. Moving connectors typically have a clamping copper contact. When the moving connector is mated with the stationary connector, the moving contact is subjected to clamping force, allowing the moving and stationary contacts to make close contact and conduct electricity. Specifically, the mating process involves the moving contact clamping the stationary contact and then sliding forward to complete the mating. The disassembly process is the same as the mating process, but the sliding direction is reversed. The contact method during this process is sliding contact with mutual friction. However, since the moving and stationary contacts are made of copper, which has low hardness, repeated insertion and separation can easily cause the contact surfaces of the connector to wear against each other. Once the contact surfaces of the connector contacts are severely worn, the conductivity will be directly reduced, affecting normal use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing connectors for power distribution cabinets, which are prone to wear on the contact surface during insertion and separation, thereby reducing the conductivity of the contacts. This invention proposes a low-wear moving connector by adding a moving contact position locking and unlocking adjustment mechanism to the moving connector, thereby effectively reducing the wear of the moving connector during the insertion and separation process with the stationary connector and extending the service life of the connector.

[0005] Technical solution

[0006] To achieve the above-mentioned technical objectives, the present invention proposes a low-wear moving connector, comprising a pair of moving contacts connected by an elastic element. The elastic element continuously provides a driving force for the pair of moving contacts to rotate in a relative direction, thereby providing a clamping force during the contact process between the pair of moving contacts and the stationary connector. The moving connector is characterized by having a moving contact position adjustment mechanism that ensures the pair of moving contacts only contact or separate from the stationary connector when they are in the insertion or separation position, thus shortening the contact process between the pair of moving contacts and the stationary connector and reducing wear between them.

[0007] Furthermore, the moving contact position adjustment mechanism includes a slider, and the pair of moving contacts are rotatably mounted on the slider. The pair of moving contacts are provided with position linkage slots. The slider is provided with position guide limiting slots corresponding to the position linkage slots. The guide block is provided with guide shafts corresponding to the position guide limiting slots and the position linkage slots. The guide shafts are placed in the position guide limiting slots and the position linkage slots.

[0008] The slider and the housing are slidably connected. The guide block is fixedly installed in the housing. One end of the spring is connected to the slider and the other end is connected to the guide block. When the spring is in its initial natural state, the spring force causes the guide shaft on the guide block to drive the pair of moving contacts to be in the open state.

[0009] The guide shaft on the guide block can slide back and forth in the position guide limiting slot. During the back and forth sliding of the guide shaft in the position guide limiting slot, it can drive the pair of moving contacts to rotate through the position linkage slot, thereby realizing the opening and closing of the pair of moving contacts.

[0010] The outer casing is provided with a guide rail, and the slider is mounted on the guide rail and slidably connected to the outer casing.

[0011] The pair of moving contacts are mounted on the slider by a pair of contact shafts and can rotate around the pair of contact shafts.

[0012] When the guide shaft slides from the end away from the pair of contact shafts to the end closer to the pair of contact shafts within the position guide limiting slot, the guide shaft, through the position linkage slot, links the pair of moving contacts to rotate in opposite directions.

[0013] The direction of movement of the guide shaft within the position guide and limiting slot is parallel to the insertion direction of the connector.

[0014] The elastic element is a tension spring, and the two ends of the tension spring are respectively mounted on the tension spring hooks of the pair of moving contacts.

[0015] The position linkage slot is an oblong or triangular hole.

[0016] One end of the spring is placed in the spring groove on the slider, and the other end is mounted on the spring post on the guide block. The extension and retraction direction of the spring is parallel to the insertion direction of the connector.

[0017] The guide block and the terminal block are fixedly connected. The guide block is fixedly installed in the housing. The housing and the terminal block are connected to external fasteners.

[0018] The junction box is T-shaped.

[0019] The pair of moving contacts and the guide block are electrically connected in the form of a surface connection.

[0020] Furthermore, the elastic element is a compression spring, which is connected to the outside of the pair of moving contacts. The compression spring continuously provides a driving force to the pair of moving contacts, causing them to rotate in opposite directions, thereby providing a clamping force during the contact between the pair of moving contacts and the stationary connector.

[0021] Furthermore, at least two springs may have one end connected to both sides of the slider, and the other end of the at least two springs may be connected to the corresponding end face of the integral assembly of the terminal block, housing, and guide block.

[0022] Furthermore, the moving contact position adjustment mechanism includes a slider, and the pair of moving contacts are rotatably mounted on the slider. The pair of moving contacts are provided with position linkage slots. A guide shaft is provided on the guide block at a position linkage slot corresponding to the position linkage slot. The guide shaft is placed in the position linkage slot, and the guide shaft of the guide block can slide back and forth in the position linkage slot. The two end faces of the guide shaft are not higher than the surface of the pair of moving contacts.

[0023] Furthermore, the moving contact position adjustment mechanism includes a slider, and a pair of moving contacts are rotatably mounted on the slider. Each pair of moving contacts is provided with a position linkage slot. A position guide limiting slot is provided on the slider at a position corresponding to the position linkage slot. A guide shaft is provided on the guide block at a position corresponding to the position guide limiting slot and the position linkage slot. The guide shaft is placed within the position guide limiting slot and the position linkage slot. The slider is directly mounted on the outer casing and slides relative to it. The guide block is fixedly mounted in the outer casing. The guide shaft, placed within the position guide limiting slot, can move back and forth, allowing the slider and the guide block to move linearly relative to each other.

[0024] Furthermore, the moving contact position adjustment mechanism includes a slider, the pair of moving contacts are rotatably mounted on the slider, the pair of moving contacts are provided with a guide shaft, the slider is provided with a position guide limiting slot corresponding to the guide shaft, the guide block is provided with a position linkage slot corresponding to the position guide limiting slot and the guide shaft, and the guide shaft is placed in the position guide limiting slot and the position linkage slot.

[0025] Furthermore, the moving contact position adjustment mechanism includes a slider, the pair of moving contacts are rotatably mounted on the slider, the guide block is provided with a position linkage slot, and the pair of moving contacts are provided with a guide shaft at a position corresponding to the position linkage slot, the guide shaft being placed in the position linkage slot;

[0026] The slider and the housing are slidably connected. The guide block is fixedly installed in the housing. One end of the spring is connected to the slider and the other end is connected to the guide block. When the spring is in its initial natural state, the spring force causes the guide block to drive the guide shaft through the position linkage slot to drive the pair of moving contacts to the open state.

[0027] The guide shaft can slide back and forth within the position linkage slot. During the back and forth sliding of the guide shaft within the position linkage slot, it can drive the pair of moving contacts to rotate, thereby realizing the opening and closing of the pair of moving contacts.

[0028] Furthermore, the moving contact position adjustment mechanism includes a slider, and a pair of moving contacts are rotatably mounted on the slider. A guide shaft is provided on the pair of moving contacts. A position guide limiting slot is provided on the slider at a position corresponding to the guide shaft. A position linkage slot is provided on the guide block at a position corresponding to the position guide limiting slot and the guide shaft. The guide shaft is placed in the position guide limiting slot and the position linkage slot. The slider is directly mounted on the outer shell and slides relative to it. The guide block is fixedly mounted in the outer shell. The guide shaft is placed in the position guide limiting slot and can move back and forth, so that the slider and the guide block can move linearly relative to each other.

[0029] Furthermore, the guide block and the wiring board can be integrated or separate.

[0030] Furthermore, the moving contact is electrically connected to the guide block or the terminal block via a flexible connection.

[0031] Beneficial effects

[0032] This invention provides a low-wear moving connector. By adding a moving contact position locking and unlocking adjustment mechanism to the moving connector, the opening and closing distance between the two moving contacts can be accurately controlled. This ensures that the sliding process during insertion is contactless and frictionless. After insertion, the moving contact clamps the stationary contact to conduct electricity. During separation, the moving contact opens first, achieving contactless sliding separation and thus zero wear. The entire process involves only a small amount of wear due to the necessary contact between the moving and stationary contacts in the conductive state. Attached Figure Description

[0052] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0053] Example 1

[0054] Existing plug-in systems used in distribution cabinets experience prolonged sliding contact friction during insertion and disengagement. This repeated sliding contact friction over extended periods can lead to severe wear on the moving contacts of the moving plug and the stationary contacts of the stationary plug, even directly reducing conductivity. To address this problem, this embodiment proposes a low-wear moving connector, as shown in the attached figure. Figure 1As shown in Figures 2 and 3, it includes a pair of moving contacts 1,1', each pair of moving contacts 1,1' comprising at least two opposing moving contact pieces. In this embodiment, the pair of moving contacts 1,1' comprises four opposing moving contact pieces arranged in pairs. An elastic element 2 connects the pair of moving contacts 1,1'. Preferably, in this embodiment, the elastic element 2 is a tension spring or a compression spring. If it is a tension spring, both ends of the tension spring are respectively mounted on tension spring hooks 101,101' on the pair of moving contacts 1,1'. If it is a compression spring, the compression spring is connected to the outside of the pair of moving contacts 1,1'. Whether it is a tension spring or a compression spring, they are just different in form, but both can continuously provide the pair of moving contacts 1,1' with a driving force that tends to rotate in the opposite direction, thereby providing clamping force during the contact between the pair of moving contacts 1,1' and the stationary insert 3 (generally referring to a vertical busbar or independent insert). The moving connector is provided with a moving contact position adjustment mechanism, which enables the pair of moving contacts 1,1' to make contact with or separate from the stationary connector 3 only when the pair of moving contacts 1,1' are in the insertion or separation position with the stationary connector 3, thereby shortening the contact process between the pair of moving contacts 1,1' and the stationary connector 3 and achieving the purpose of reducing wear between the pair of moving contacts 1,1' and the stationary connector 3.

[0055] Further explanation of the above components, in conjunction with the accompanying drawings, is as follows: Figure 2 and 4 As shown, the moving contact position adjustment mechanism includes a slider 4, and a pair of moving contacts 1, 1' are rotatably mounted on the slider 4. Specifically, in this embodiment, the pair of moving contacts 1, 1' are mounted on the slider 4 via a pair of contact shafts 5, 5' and can rotate around the pair of contact shafts 5, 5'. (See attached diagram) Figure 2 and 8a As shown, the pair of moving contacts 1, 1' are provided with position linkage slots 102, 102', as illustrated in the attached figure. Figure 2 and 9 As shown in Figures 2 and 10, position guide and limiting slots 401 and 401' are provided on the slider 4 at positions corresponding to the position linkage slots 102 and 102'. Guide shafts 601 and 601' are provided on the guide block 6 at positions corresponding to the position guide and limiting slots 401 and 401' and the position linkage slots 102 and 102', and the guide shafts 601 and 601' are placed within the position guide and limiting slots 401 and 401' and the position linkage slots 102 and 102'. The slider 4 and the outer casing 7 are relatively slidably connected, specifically as shown in the attached figures. Figure 2 and 5 As shown, the outer casing 7 is provided with the attached... Figure 11 The guide rails 8 and 8' are shown, and the slider 4 is mounted on the guide rails 8 and 8' and is slidably connected to the housing 7.

[0056] As attached Figure 2 As shown, the guide block 6 is fixedly mounted on the attached... Figure 7 In the housing 7 shown, the guide plate 6 and the terminal block 9 are either integral or separate. In this embodiment, the separate type is preferred. The guide plate 6 and the terminal block 9 are fixedly connected using fasteners. The housing 7 and the terminal block 9, preferably T-shaped, are connected to external fasteners. In this embodiment, there are multiple ways to achieve electrical connection. For example, the pair of moving contacts 1,1' and the guide plate 6 are electrically connected via a surface connection; or the pair of moving contacts 1,1' and the guide plate 6, or the pair of moving contacts 1,1' and the terminal block 9, are electrically connected using copper foil strips, copper braided strips, or copper braided wires. (See attached...) Figure 2 and 6 As shown, one end of the spring 10 is connected to the slider 4, and the other end is connected to the guide block 6. In this embodiment, one end of the spring 10 is placed in the spring groove 402 on the slider 4, and the other end is mounted on the spring post 602 on the guide block 6. The extension and retraction direction of the spring 10 is parallel to the insertion direction of the connector. The ends of the position guide limiting slots 401, 401' away from the pair of contact shafts 5, 5' can play a limiting role. When the spring 10 is in the initial working state, the spring 10 makes the slider 4 away from the guide block 6. At this time, the guide shafts 601, 601' abut against the ends of the corresponding position guide limiting slots 401, 401' away from the pair of contact shafts 5, 5', so that the spring 10 has a certain initial working force. This initial working force ensures that the pair of moving contacts 1, 1' will not shake or have their spacing reduced due to the tension of the elastic element 2. Figure 12As shown, when the spring 10 is in its initial working state, the spring force of the spring 10 causes the guide shafts 601, 601' on the guide block 6 to drive the pair of moving contacts 1, 1' into an open state. When the spring 10 is in its initial working state, the gap between the pair of moving contacts 1, 1' is larger than the thickness of the stationary contact of the stationary plug-in 3, so that the pair of moving contacts 1, 1' do not contact the stationary contact. During the relative sliding process of insertion and separation, the lack of contact between the pair of moving contacts 1, 1' and the stationary contact can avoid wear. When the moving plug-in and the stationary plug-in 3 are inserted and connected, the spring 10 is compressed. When the moving plug-in and the stationary plug-in 3 are separated, the spring 10 can preferentially reset the guide shafts 601, 601' to the position furthest away from the stationary plug-in 3 within the position guide limiting slots 401, 401'. That is, the moving plug and the stationary plug 3 are released from contact first, and then the moving plug is completely separated from the stationary plug 3, thereby avoiding contact and friction between the moving and stationary contacts during separation. The guide shafts 601 and 601' of the guide block 6 can slide back and forth within the position guide limiting slots 401 and 401'. Generally speaking, the direction of movement of the guide shafts 601 and 601' within the position guide limiting slots 401 and 401' is preferably parallel to the insertion direction of the connector to achieve the best motion transmission effect. During the back and forth sliding of the guide shafts 601 and 601' within the position guide limiting slots 401 and 401', the pair of moving contacts 1 and 1' can be rotated through the position linkage slots 102 and 102' to realize the opening and closing of the pair of moving contacts 1 and 1'. When the guide shafts 601 and 601' slide within the position guide limiting slots 401 and 401' from the end away from the pair of contact rotating shafts 5 and 5' to the end closer to the pair of contact rotating shafts 5 and 5', the guide shafts 601 and 601' are linked by the position linkage slots 102 and 102' to rotate the pair of moving contacts 1 and 1' in opposite directions. When the guide shafts 601 and 601' move to the end closer to the pair of contact rotating shafts 5 and 5' within the position guide limiting slots 401 and 401', the pair of moving contacts 1 and 1' clamp the stationary connector 3 as shown in the attached figure. Figure 13 As shown in the attached figure. In this embodiment, the position guide limiting slots 401 and 401' are straight slots with arc-shaped ends, and the position linkage slots 102 and 102' are preferably as shown in the attached figure. Figure 8a Waist-shaped hole or as attached Figure 8b The triangular hole. However, it should be noted that the shapes of the position linkage slots 102, 102' and the position guide limiting slots 401, 401' are not limited to the shapes provided in this embodiment. Any shape of the position linkage slots 102, 102' and the position guide limiting slots 401, 401' that can achieve the technical purpose of this embodiment should be considered as the shape claimed by this invention.

[0057] In this embodiment, when the moving plug and the stationary plug 3 are inserted, the slider 4 first contacts the stationary plug 3 and then comes to a stop. The outer shell 7 continues to be under pressure, and the guide block 6 is brought closer to the stationary plug 3 by the outer shell 7. The spring 10 is squeezed and compressed by the guide block 6, and the guide shafts 601, 601' slide along the position guide limiting slots 401, 401', guiding the position linkage slots 102, 102' of a pair of moving contacts 1, 1' to rotate and change the angle, so that the pair of moving contacts 1, 1' clamp the stationary contact of the stationary plug 3 under the pulling force of the elastic member 2.

[0058] When the moving plug leaves the stationary plug 3, the guide block 6 moves together with the outer shell 7. Under the action of the spring force, the slider 4 will temporarily remain in contact with the stationary plug 3. The guide shafts 601, 601' gradually slide along the position guide limiting slots 401, 401' away from the pair of contact shafts 5, 5', thereby gradually guiding the pair of moving contacts 1, 1' to open. At this time, the pair of moving contacts 1, 1' disengages from the stationary plug 3 until the guide shafts 601, 601' move to the farthest end of the position guide limiting slots 401, 401' away from the pair of contact shafts 5, 5'. At this time, the slider 4 and the pair of moving contacts 1, 1' separate from the stationary plug 3 together with the outer shell 7.

[0059] Example 2

[0060] As attached Figure 14a and 14b As shown, in another embodiment of the present invention, the moving contact position adjustment mechanism includes a slider 4, and a pair of moving contacts 1, 1' are rotatably mounted on the slider 4. The pair of moving contacts 1, 1' are provided with position linkage slots 102, 102'. The difference from embodiment 1 is that in this embodiment, the slider 4 does not have position guide limiting slots 401, 401' corresponding to the position linkage slots 102, 102', and the guide block 6 has... The guide block 6 has guide shafts 601 and 601' positioned within the position linkage slots 102 and 102'. The guide shafts 601 and 601' of the guide block 6 can slide back and forth within the position linkage slots 102 and 102', and the two end faces of the guide shafts 601 and 601' are not higher than the surfaces of the pair of moving contacts 1 and 1'. If the two end faces of the guide shafts 601 and 601' are higher than the surfaces of the pair of moving contacts 1 and 1', then clearance holes must be provided at corresponding positions on the slider 4. Other structures and operating processes are the same as in Embodiment 1.

[0061] In this embodiment, the slider 4 is mounted on the guide rails 8, 8' and slidably connected to the outer shell 7. The guide block 6 is fixedly mounted in the outer shell 7. The relative linear movement of the slider 4 and the guide rails 8, 8' of the outer shell 7 enables the slider 4 and the guide block 6 to move relatively linearly. The ends of the position linkage slots 102, 102' away from the pair of contact shafts 5, 5' can play a limiting role. When the spring 10 is in the initial working state, the spring 10 keeps the slider 4 away from the guide block 6. At this time, the guide shafts 601, 601' abut against the ends of the corresponding position linkage slots 102, 102' away from the pair of contact shafts 5, 5', so that the spring 10 has a certain initial working force. This initial working force ensures that the pair of moving contacts 1, 1' will not shake or have their spacing reduced due to the tension of the elastic element 2.

[0062] Example 3

[0063] The present invention also provides an embodiment in which the moving contact position adjustment mechanism includes a slider 4, and a pair of moving contacts 1, 1' are rotatably mounted on the slider 4. The pair of moving contacts 1, 1' are provided with position linkage slots 102, 102'. The slider 4 is provided with position guide limiting slots 401, 401' corresponding to the position linkage slots 102, 102'. The guide block 6 is provided with guide shafts 601, 601' corresponding to the position guide limiting slots 401, 401' and the position linkage slots 102, 102'. The guide shafts 601, 601' are placed in the position guide limiting slots 401, 401' and the position linkage slots 102, 102'. In this embodiment, no relative sliding connection structure is provided between the slider 4 and the outer shell 7, that is, the outer shell 7 is not provided with guide rails 8, 8' as shown in Figure 11. The guide block 6 is fixedly installed in the outer shell 7. The guide shafts 601, 601' are placed in the position guide limiting slots 401, 401' and can move back and forth so that the slider 4 and the guide block 6 can move relatively linearly. The ends of the position guide limiting slots 401, 401' away from the pair of contact rotating shafts 5, 5' can play a limiting role. When the spring 10 is in the initial working state, the spring 10 makes the slider 4 in a state away from the guide block 6. At this time, the guide shafts 601, 601' abut against the corresponding ends of the position guide limiting slots 401, 401' away from the pair of contact rotating shafts 5, 5', so that the spring 10 has a certain initial working force. This initial working force ensures that the pair of moving contacts 1, 1' will not shake or have their spacing reduced due to the tension of the elastic element 2. Other structures and working processes are the same as in Embodiment 1.

[0064] Example 4

[0065] In another embodiment of the present invention, the moving contact position adjustment mechanism includes a slider 4, and a pair of moving contacts 1, 1' are rotatably mounted on the slider 4. Specifically, in this embodiment, the pair of moving contacts 1, 1' are mounted on the slider 4 via a pair of contact shafts 5, 5' and can rotate around the pair of contact shafts 5, 5'. The pair of moving contacts 1, 1' are provided with guide shafts 601, 601', and the slider 4 is provided with position guide limiting slots 401, 401' at corresponding positions to the guide shafts 601, 601'. The guide block 6 is provided with position linkage slots 102, 102' at corresponding positions to the position guide limiting slots 401, 401' and the guide shafts 601, 601', and the guide shafts 601, 601' are placed within the position guide limiting slots 401, 401' and the position linkage slots 102, 102'. The slider 4 is slidably connected to the outer casing 7. Specifically, the outer casing 7 is provided with guide rails 8, 8', and the slider 4 is mounted on the guide rails 8, 8' and slidably connected to the outer casing 7. This embodiment differs from Embodiment 1 in that the guide shafts 601, 601' are disposed on the pair of moving contacts 1, 1', and the position linkage slots 102, 102' are disposed on the guide block 6. Other structures and working processes are the same as in Embodiment 1.

[0067] In another embodiment of the present invention, the moving contact position adjustment mechanism includes a slider 4, a pair of moving contacts 1, 1' rotatably mounted on the slider 4, position linkage slots 102, 102' disposed on the guide block 6, and guide shafts 601, 601' disposed on the pair of moving contacts 1, 1' at positions corresponding to the position linkage slots 102, 102'. The guide shafts 601, 601' are placed in the position linkage slots 102, 102'. The slider 4 is slidably connected to the outer casing 7, the guide block 6 is fixedly mounted in the outer casing 7, and one end of the spring 10 is connected to the slider 4, and the other end is connected to the guide block 6. In this embodiment, the position linkage slots 102, 102' are set on the guide block 6, and the guide shafts 601, 601' are set on a pair of moving contacts 1, 1'. The position guide limiting slots 401, 401' in embodiment 1 are eliminated. The guide shafts 601, 601' can slide back and forth in the position linkage slots 102, 102'. During the back and forth sliding of the guide shafts 601, 601' in the position linkage slots 102, 102', they can link the rotation of the pair of moving contacts 1, 1' to realize the opening and closing of the pair of moving contacts 1, 1'.

[0068] When the spring 10 is in its initial working state, the spring force of the spring 10 causes the guide block 6 to drive the guide shaft 601, 601' through the position linkage slots 102, 102' to drive the pair of moving contacts 1, 1' into an open state. At this time, the ends of the position linkage slots 102, 102' that are away from the pair of contact shafts 5, 5' play a limiting role. Specifically, the spring 10 causes the slider 4 to move away from the guide block 6, and the guide shafts 601, 601' abut against the ends of the position linkage slots 102, 102' that are away from the pair of contact shafts 5, 5', so that the spring 10 has a certain initial working force. This initial working force ensures that the pair of moving contacts 1, 1' will not shake or have their spacing reduced due to the tension of the elastic element 2. When pushed forward, slider 4 first contacts the stationary contact and then stops moving, while guide block 6 continues to move forward, causing guide shafts 601 and 601' to move in position linkage slots 102 and 102', causing a pair of moving contacts 1 and 1' to close. The other end of the position linkage slots 102 and 102' does not serve as a limit, but rather as a clearance.

[0069] Example 6

[0070] Based on Embodiment 4, in another embodiment provided by the present invention, the moving contact position adjustment mechanism includes a slider 4, and the pair of moving contacts 1, 1' are rotatably mounted on the slider 4. Specifically, in this embodiment, the pair of moving contacts 1, 1' are mounted on the slider 4 via a pair of contact shafts 5, 5' and can rotate around the pair of contact shafts 5, 5'. The pair of moving contacts 1, 1' are provided with guide shafts 601, 601', and the slider 4 is provided with position guide limiting slots 401, 401' at corresponding positions to the guide shafts 601, 601' and the position linkage slots 102, 102'. Position linkage slots 102 and 102' are provided on the guide block 6 at positions corresponding to the position guide limiting slots 401 and 401' and the guide shafts 601 and 601', respectively. The guide shafts 601 and 601' are placed in the position guide limiting slots 401 and 401' and the position linkage slots 102 and 102'. The guide shafts 601 and 601' are disposed on the pair of moving contacts 1 and 1', and the position linkage slots 102 and 102' are disposed on the guide shafts 601 and 601'. This embodiment differs from embodiment 4 in that there is no relative sliding connection structure between the slider 4 and the outer shell 7, that is, the outer shell 7 is not provided with the aforementioned connection structure. Figure 11The guide rails 8, 8' shown are shown. The guide block 6 is fixedly installed in the housing 7. The guide shafts 601, 601' are placed in the position guide limiting slots 401, 401' and can move back and forth, allowing the slider 4 and the guide block 6 to move linearly relative to each other. Other structures and working processes are the same as in Embodiment 1. The ends of the position guide limiting slots 401, 401' away from the pair of contact shafts 5, 5' can play a limiting role. When the spring 10 is in the initial working state, the spring 10 keeps the slider 4 away from the guide block 6. At this time, the guide shafts 601, 601' abut against the ends of the corresponding position guide limiting slots 401, 401' away from the pair of contact shafts 5, 5', giving the spring 10 a certain initial working force. This initial working force ensures that the pair of moving contacts 1, 1' will not shake or have their spacing reduced due to the tension of the elastic element 2. Other structures and working processes are the same as in Embodiment 3.

[0071] Example 7

[0072] The spring 10 mounting structure of the present invention is not limited to the structure described in Embodiment 1. In this embodiment, the spring 10 can also be mounted in a way in which one end of at least two springs 10 is connected to both sides of the slider 4, and the other end of the at least two springs 10 is connected to the corresponding end face of the whole consisting of the wiring plate 9, the housing 7, and the guide block 6. It should be noted that the mounting methods of the spring 10 are diverse, and the mounting methods shown in the embodiments of the present invention should be considered to fall within the scope of protection claimed by the present invention.

[0073] This invention provides a low-wear moving connector. By adding a moving contact position locking and unlocking adjustment mechanism to the moving connector, the opening and closing distance between the two moving contacts can be accurately controlled. This ensures that the sliding process during insertion is contactless and frictionless. After insertion, the moving contact clamps the stationary contact to conduct electricity. During separation, the moving contact opens first, achieving contactless sliding separation and thus zero wear. The entire process involves only a small amount of wear due to the necessary contact between the moving and stationary contacts in the conductive state.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
