Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of power distribution cabinet, and particularly relates to a low-wear dynamic connector with a guiding function. BACKGROUND

[0002] In modern power distribution networks and engineering construction, the draw-out type low-voltage power distribution cabinet is widely used in power plants, substations and other occasions. As power distribution, motor control and lighting lamp power distribution equipment, the power distribution cabinet plays an important role in power conversion, distribution and control. This type of power distribution cabinet has the advantages of saving space, reliable operation, convenient installation and maintenance, strong breaking capacity, and multiple outgoing circuits.

[0003] The primary connector is mainly used for the primary line (i.e. the main line) in the power distribution cabinet. The circuit is completed by the contact of the dynamic connector and the static connector. The separation of the dynamic connector and the static connector completes the circuit disconnection. The static connector is usually a static copper contact, and the dynamic connector is usually a dynamic copper contact with clamping force. When the dynamic connector is inserted into the static connector, the dynamic contact is clamped by the clamping force, and the dynamic contact and the static contact can be tightly contacted and conducted. Since the insertion process is the further sliding forward of the dynamic contact after the clamping and contacting of the static contact, the separation process is consistent with the contacting of the dynamic contact and the static contact, and the sliding direction is opposite. This contact method is a sliding contact with mutual friction. However, since the material of the dynamic contact and the static contact is copper, which has low hardness, repeated insertion and separation can easily cause mutual wear of the contact surfaces of the contacts, and severe wear of the contact surfaces of the contacts can directly reduce the conductivity and affect normal use. SUMMARY

[0004] The present application is aimed at the above-mentioned defects of the existing power distribution cabinet connector, which is prone to wear of the contact surfaces of the contacts during insertion and separation, thereby reducing the conductivity of the contacts.

The guiding mechanism avoids direct impact and contact between the static connector and the dynamic contact, and the dynamic contact position adjusting mechanism is added to the dynamic connector, thereby effectively reducing the wear of the dynamic connector during insertion and separation with the static connector, and prolonging the service life of the connector.

[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. Furthermore, when the stationary plug initially contacts the moving plug, it cannot accurately and gradually move between the two pairs of moving contacts, resulting in impact damage at the moment of contact. To address this problem, this embodiment proposes a low-wear moving plug with a guiding function, as shown in the attached figure. Figure 1 As shown in Figures 2 and 3, a pair of moving contacts 1,1' is included. Each pair of moving contacts 1,1' comprises at least two opposing moving contact pieces. In this embodiment, the pair of moving contacts 1,1' comprises four opposing moving contact pieces, as shown in the attached figure. Figure 9 An elastic element 2 connects the pair of moving contacts 1, 1' shown. 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 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, the only difference is the form of the spring; the technical principle is the same. 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 a 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 an independent insert). When the tension spring 2 drives the pair of moving contacts 1, 1' to rotate and close in the opposite direction, the rotation stroke can be limited by the limiting protrusion 7a. In this embodiment, the limiting protrusion 7a is a protrusion on the slider 7.

[0055] As attached Figure 2 and 6As shown, the moving connector is provided with a guide mechanism and a moving contact position adjusting mechanism. The guide mechanism can guide the static connector 3 during the insertion process with the pair of moving contacts 1, 1' to avoid collision damage between the static connector 3 and the pair of moving contacts 1, 1'. The moving contact position adjusting mechanism can make the pair of moving contacts 1, 1' contact or separate from the static connector 3 only when the pair of moving contacts 1, 1' is in the insertion or separation position with the static connector 3, thereby shortening the process of contacting the pair of moving contacts 1, 1' with the static connector 3 and achieving the purpose of reducing the wear between the pair of moving contacts 1, 1' and the static connector 3.

[0056] The above components are further described in combination with the accompanying drawings, and as shown in Figure 2 , 4 and 7, the guide mechanism includes a pair of roller supports 4, 4' as shown in Figure 13 , the pair of roller supports 4, 4' are rotatably connected with the corresponding pair of moving contacts 1, 1', one end of the pair of roller supports 4, 4' is provided with a guide roller 5, 5', and the other end is provided with a roller position adjusting slot hole 401, 401'. The pair of roller supports 4, 4' are connected with the moving contact position adjusting mechanism through the roller position adjusting slot hole 401, 401'. In this embodiment, the pair of roller supports 4, 4' are mounted on the upper end side of the pair of moving contacts 1, 1' through roller support rotating shafts 6, 6'. The guide rollers 5, 5' on the pair of roller supports 4, 4' are located on the front side of the contact end of the pair of moving contacts 1, 1'. The guide roller structure can avoid the direct contact impact damage of the moving connector with the static connector 3 at the moment of contact, and the rolling friction resistance of the roller is small, which is more labor-saving.

[0057] As shown in Figure 2 , 4 and 7, the moving contact position adjusting mechanism includes a slider 7 as shown in Figure 10 , the pair of moving contacts 1, 1' are rotatably mounted on the slider 7. Specifically, as shown in Figure 2 , the pair of moving contacts 1, 1' are mounted on the slider 7 through a pair of contact rotating shafts 8, 8' and can rotate around the pair of contact rotating shafts 8, 8'. The pair of moving contacts 1, 1' are provided with position linkage slot holes 102, 102'. A pair of guide blocks 9, 9' as shown in Figure 11 are correspondingly arranged on the pair of moving contacts 1, 1'. One end of the pair of guide blocks 9, 9' is provided with corresponding guide shafts 901, 901' corresponding to the roller position adjusting slot holes 401, 401' and the position linkage slot holes 102, 102'. Specifically, as shown in Figure 11As shown, the guide shaft 901, 901' is located between two guide pieces 902, 902' in each of the pair of guide blocks 9, 9', and the two guide pieces 902, 902' in each of the guide blocks 9, 9' are wrapped around the corresponding movable contact piece and roller support 4, 4', or: each of the guide blocks 9, 9' includes one guide piece, and the guide shaft 901, 901' is directly located on the guide piece in the corresponding guide block 9, 9', and the guide block 9, 9' is located between the corresponding movable contact 1, 1' or between the movable contact 1, 1' and the roller support 4, 4'.

[0058] The guide shaft 901, 901' is located in the roller position adjusting slot hole 401, 401' and the position linkage slot hole 102, 102', and the other end of the pair of guide blocks 9, 9' is pivotally mounted on the sliding pin 11 of the push plate 10, and the sliding pin 11 is located in the limiting stroke hole 701 on the sliding block 7 and can slide in the direction parallel to the insertion direction of the connector. The sliding block 7 is connected to the shell 12 as shown in the figure by relative sliding, and in this embodiment, the push plate 10 is fixedly connected to the wiring board 13, and the wiring board 13 is fixedly connected to the shell 12, and further, the shell 12, the push plate 10 and the wiring board 13 are integrally fixedly connected. The pair of movable contacts 1, 1' and the sliding block 7 are electrically connected in the form of surface contact, and the sliding block 7 and the push plate 10 are electrically connected in the form of surface contact. Figure 8

[0059] As shown in the figure, the shell 12 is provided with a wiring board 13, and the wiring board 13 is provided with a plurality of electrical contacts 131, 131' corresponding to the movable contacts 1, 1' of the connector. Figure 2 5 As shown in the figure, the shell 12 is provided with a wiring board 13, and the wiring board 13 is provided with a plurality of electrical contacts 131, 131' corresponding to the movable contacts 1, 1' of the connector. Figure 12 ​​The guide rail 14 is shown, the slider 7 is connected between the guide rail 14 and the shell 12 relative sliding. The spring 15 is connected to the slider 7 at one end and to the terminal board 13 or the push plate 10 at the other end. When the spring 15 is in the initial working state, the spring force of the spring 15 drives the guide shaft 901, 901' on the pair of guide blocks 9, 9' to drive the pair of moving contacts 1, 1' to be in the open state (at this time, the distance between the pair of moving contacts 1, 1' can be greater than or equal to the thickness of the static contact, or less than the thickness of the static contact) and drives the guide rollers 5, 5' on the pair of roller supports 4, 4' to be in the folding guide state (that is, the distance between the guide rollers 5, 5' is less than the distance between the pair of moving contacts 1, 1', that is, inside the moving contacts 1, 1'). Further, in the embodiment, the spring 15 is arranged in the spring positioning column 702 on the slider 7 at one end, and is arranged on the spring positioning groove of the terminal board 13 or the spring positioning groove of the push plate 10 at the other end. The extension direction of the spring 15 is parallel to the insertion direction of the connector. In addition, in the embodiment, the spring 15 has another installation mode, that is, at least two springs 15 are connected to the two sides of the slider 7 at one end, and are connected to the terminal board 13 or the push plate 10 at the other end. When the moving connector and the static connector are inserted and connected, the spring 15 is compressed. When the moving connector and the static connector 3 are separated, the spring 15 can be preferentially reset, the guide shaft 901, 901' is in the position linkage groove hole 102, 102' farthest from the position of the static connector 3, so that the gap between the guide rollers 5, 5' is reduced.

[0060] The guide shafts 901, 901' on the pair of guide blocks 9, 9' can slide in the position linkage grooves 102, 102', and the guide shafts 901, 901' can link the pair of roller supports 4, 4' to rotate through the roller position adjustment grooves 401, 401' during back-and-forth sliding in the position linkage grooves 102, 102', so as to realize opening and closing of the pair of roller supports 4, 4', and simultaneously link the pair of movable contacts 1, 1' to be opened and closed under the joint action of the elastic members. In the embodiment, the position linkage grooves 102, 102' are straight grooves, and the roller position adjustment grooves 401, 401' are arc-shaped holes or waist-shaped holes or triangular holes, but it should be noted that the shapes of the position linkage grooves 102, 102' and the roller position adjustment grooves 401, 401' are not limited to the shapes provided in the embodiment, and any shape of the position linkage grooves 102, 102' and the roller position adjustment grooves 401, 401' that can achieve the technical purpose of the embodiment should be considered as shapes claimed by the application. During back-and-forth sliding of the guide shafts 901, 901' in the position linkage grooves 102, 102', the structure that the guide shafts 901, 901' link the pair of roller supports 4, 4' to rotate through the roller position adjustment grooves 401, 401' can control the guide rollers 5, 5' or the movable contacts 1, 1' to contact the static contacts as needed, and avoid the wear interval as needed.

[0061] In the embodiment, as shown in FIG. 1, the position linkage grooves 102, 102' are straight grooves, and the roller position adjustment grooves 401, 401' are arc-shaped holes or waist-shaped holes or triangular holes. Figure 14As shown, when the moving plug and the static plug are ready to be inserted, the guide shaft 901, 901' is placed in the roller position adjusting slot hole 401, 401' and the position linkage slot hole 102, 102' away from the roller support shaft 6, 6', the edge of the guide roller 5, 5' closest to the plug center line is inside the contact surface of the moving contact 1, 1', and the gap between the two side guide rollers 5, 5' is smaller than that of the static contact. When the moving plug is pushed forward, the guide roller 5, 5' is pushed away by the static contact and rolls along the outer wall of the static contact into the static plug. This process causes the gap between the pair of moving contacts 1, 1' to be larger than the gap between the guide rollers 5, 5', so that the pair of moving contacts 1, 1' are not in contact with the static contact. When the pair of moving contacts 1, 1' are subjected to the pulling force of the elastic member 2, the guide roller 5, 5' contacts the static contact, and the relative positions of the pair of moving contacts 1, 1', the guide roller 5, 5' and the guide block 9, 9' remain unchanged. Continue to push, the slider 7 is in contact with the static plug and is stationary, the outer shell 12 of the moving plug continues to be pressed, the spring 15 is compressed by the wiring board 13, the guide block 9, 9' is continuously close to the static plug 3 with the outer shell 12, the guide shaft 901, 901' slides along the position linkage slot hole 102, 102', the roller position adjusting slot hole 401, 401' of the guide roller support 4, 4' changes the relative angle with the pair of moving contacts 1, 1' to make the guide roller support 4, 4' open the guide roller 5, 5', when the guide shaft 901, 901' is placed in the roller position adjusting slot hole 401, 401' and the position linkage slot hole 102, 102' close to the roller support shaft 6, 6', the edge of the guide roller 5, 5' closest to the plug center line is outside the contact surface of the moving contact 1, 1', the gap between the two side guide rollers 5, 5' is larger than the gap between the pair of moving contacts 1, 1', the guide roller 5, 5' leaves the static contact, and the pair of moving contacts 1, 1' clamps the static contact to conduct. The pair of moving contacts 1, 1' tightly clamps the static contact of the static plug 3 under the pulling force of the elastic member 2, as shown in the figure. Figure 15 As shown.

[0062] When the moving plug leaves the static plug 3, the guide block 9, 9' moves away from the static plug 3 with the outer shell 12, the slider 7 temporarily keeps close to the static plug 3 under the elastic force of the spring 15, the guide shaft 901, 901' gradually moves away from the roller support shaft 6, 6' along the position linkage slot hole 102, 102', gradually guiding the angle between the guide roller supports 4, 4' to become smaller, the gap between the guide rollers 5, 5' becomes smaller to contact the static contact, and the pair of moving contacts 1, 1' are separated, at this time the pair of moving contacts are separated from the static contact, until the guide shaft 901, 901' moves to the farthest end of the position linkage slot hole 102, 102' away from the roller support shaft 6, 6', at this time the slider 7 separates from the static plug 3 with the moving plug outer shell 12 as a whole.

[0063] Example 2

[0064] In one embodiment provided by the present invention, as shown in the accompanying drawings, Figures 16-22 As shown, a flexible connection 16 conducts electricity between a pair of moving contacts 1,1' and push block 10, or between the pair of moving contacts 1,1' and terminal block 13, or between the pair of moving contacts 1,1' and guide blocks 9,9'. The other structures are the same as in Embodiment 1. By adopting this structure, the internal conductive contact method of the pair of moving contacts of the moving plug is changed to a fixed connection of flexible conductors, which reduces the loop resistance. The two ends of the flexible conductor are fixed to ensure that the resistance between the moving conductive parts inside the plug is stable and consistent.

[0065] This invention provides a low-wear moving connector with a guiding function. It utilizes rollers to guide the moving contact's forward path while accurately controlling the opening and closing distance between the two moving contacts. This ensures a contactless and frictionless sliding process during insertion. After insertion, the rollers are guided open by a guide shaft. Under the tension of an elastic element, the moving contact clamps the stationary contact to conduct. During separation, the rollers' opening distance is preferentially reduced to less than the opening distance of the moving contact, thus separating the moving and stationary contacts. The separation process involves only rolling wear of the rollers and minimal wear from the contact between the moving and stationary contacts during conduction. Simultaneously, the guiding function of the rollers prevents impact damage between the stationary connector and the pair of moving contacts upon contact.

[0066] 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.
