Description

Technical Field

[0001] The utility model relates to the technical field of servo drivers, in particular to a hidden electrical connection mechanism between functional modules of a servo driver. Background Art

[0002] Servo drives, also known as "servo controllers" and "servo amplifiers", are controllers used to control servo motors. They function similarly to frequency converters acting on ordinary AC motors. They are part of the servo system and are mainly used in high-precision positioning systems. They are suitable for industrial control fields such as palletizing, wire cutting, punching, lasers, and 3C. Generally, servo motors are controlled by position, speed, and torque to achieve high-precision transmission system positioning. They are high-end products of transmission technology. The working principle is: first, the input three-phase AC power is rectified to obtain the corresponding DC voltage, and then the DC power is converted into AC output power with adjustable frequency and voltage through the drive circuit to drive the corresponding servo motor.

[0003] In order to realize the above functions, they are modularized according to different functions, thereby forming a rectifier module for realizing the rectifier function and an inverter module for realizing the inverter function. In order to facilitate the installation between the modules, a plug-in conductive mechanism is generally set on the side of each module. It is common to preset plugs and sockets on two adjacent modules. When the two are connected side by side, the plug of the left functional module is directly inserted into the socket of the right functional module to realize the electrical connection.

[0004] However, when a functional module does not need to be electrically connected to an adjacent functional module, the extended plug not only takes up space, but is also easily damaged by the external environment due to long-term exposure to the air, such as rusting due to external moisture pollution, or electrical conduction with the outside, thereby causing damage to the functional module.

[0005] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to overcome the above-mentioned problems of the prior art and provide a hidden electrical connection mechanism between functional modules of a servo drive, which can effectively solve the technical problems in the prior art that the plug extending from the functional module of the servo drive not only takes up space, but is also easily damaged by the external environment due to long-term exposure to the air, and accidentally conducts electricity with the outside, thereby causing damage to the functional module.

[0007] The above objectives are achieved through the following technical solutions:

[0008] A hidden electrical connection mechanism between functional modules of a servo drive, comprising a busbar seat arranged on the functional module, wherein mutually parallel busbar copper bar embedding grooves are provided on the busbar seat, and mutually symmetrical busbar copper bars are respectively embedded in two of the busbar copper bar embedding grooves;

[0009] The same end of the two busbar copper bars embedded in the grooves serves as the first electrical connection end, and the other end serves as the second electrical connection end;

[0010] A connecting copper bar is movably connected to the busbar copper bar corresponding to the first electrical connection end, and the connecting copper bar can extend out of the first electrical connection end to be electrically connected to the second electrical connection end of the adjacent functional module; or be completely retracted into the busbar copper bar embedding groove for hiding.

[0012] Furthermore, a plurality of busbar copper bar mounting holes are provided on the busbar copper bar, and busbar copper bar mounting screws are connected to the bottom wall of the busbar copper bar embedding groove through the busbar copper bar mounting holes.

[0015] Furthermore, the connecting copper bar is movably connected to the busbar copper bar through the first electrical connecting screw; and the connecting copper bar of the adjacent functional module is movably connected to the busbar copper bar through the second connecting screw.

[0016] Furthermore, the connecting copper bar includes a U-shaped groove opened at the end, and a waist-shaped groove coaxial with the U-shaped groove; the U-shaped groove is used to be screwed with the second electrical connection screw of the adjacent functional module, and the waist-shaped groove is used for the first electrical connection screw to be screwed.

[0017] Furthermore, a first plug-in board slot capable of receiving a first plug-in board is provided at the first electrical connection end; correspondingly, a second plug-in board slot capable of receiving a second plug-in board is provided at the second electrical connection end.

[0018] Furthermore, a third plug-in board slot for the first plug-in board to be plugged into is provided adjacent to the first plug-in board slot. When the connecting copper bar is extended, the rear end of the connecting copper bar is blocked by plugging the first plug-in board into the third plug-in board slot.

[0019] Furthermore, the width of the connecting copper bar is equal to the width of the busbar copper bar.

[0020] The utility model provides a hidden electrical connection mechanism between functional modules of a servo drive, which is provided with a connecting copper bar that can move relative to the busbar copper bar. The extension of the connecting copper bar is manually adjusted to achieve the plugging of the second electrical connection end on the adjacent functional module in the extended state; the contraction movement of the connecting copper bar is manually adjusted to achieve the hidden storage of the connecting copper bar in the non-electrical connection state. The mechanism is not only simple in structure and easy to operate, but also has a good electrical connection effect, which can effectively improve the electrical connection efficiency between adjacent functional modules and extend the service life of the functional modules.

[0032] The utility model is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1 and Figure 2 As shown, a hidden electrical connection mechanism between functional modules of a servo drive comprises a busbar seat 1 arranged on a functional module 10, wherein mutually parallel busbar copper bar embedding grooves 101 are provided on the busbar seat 1, and mutually symmetrical busbar copper bars 2 are respectively embedded in two of the busbar copper bar embedding grooves 101;

[0034] The same end of the two busbar copper bar embedding grooves 101 serves as a first electrical connection end 102, and the other end serves as a second electrical connection end 103;

[0035] The busbar copper bar 2 corresponding to the first electrical connection end 102 is movably connected with a connecting copper bar 3, and the connecting copper bar 3 can extend out of the first electrical connection end 102 to be electrically connected to the second electrical connection end 103 of the adjacent functional module 10; or be completely retracted into the busbar copper bar embedding groove 101 for hiding.

[0036] In addition, if Figure 3 As shown, a matching top cover 4 is also provided on the busbar seat 1 for sealing the components provided in the busbar seat 1 .

[0037] like Figure 2 As shown, in this embodiment, a plurality of busbar copper bar mounting holes 201 are provided on the busbar copper bar 2, and the busbar copper bar mounting screws 9 are connected to the bottom wall of the busbar copper bar embedding groove 101 through the busbar copper bar mounting holes 201, so that the busbar copper bar 2 is firmly installed in the busbar copper bar embedding groove 101; the busbar copper bar mounting holes 201 are located in the middle section of the busbar copper bar 2.

[0038] A first electrical connection screw hole 202 is provided on the busbar copper bar 2 adjacent to the first electrical connection end 102, and a first electrical connection screw 7 is connected to the bottom wall of the busbar copper bar embedding groove 101 through the first electrical connection screw hole 202;

[0039] Correspondingly, a second electrical connection screw hole 203 is provided on the busbar copper bar 2 adjacent to the second electrical connection end 103, and the second electrical connection screw 8 is connected to the bottom wall of the busbar copper bar embedding groove 101 through the second electrical connection screw hole 203;

[0040] In this embodiment, the first electrical connection screw 7 and the second electrical connection screw 8 not only have the function of fastening the two ends of the busbar copper bar 2, but also have the function of electrically connecting the connecting copper bar 3 with the busbar copper bar 2.

[0041] The connecting copper bar 3 is movably connected to the busbar copper bar 2 via the first electrical connecting screw 7 ; the connecting copper bar 3 of the adjacent functional module 10 is movably connected to the busbar copper bar 2 via the second connecting screw 8 .

[0042] In order to facilitate the expansion and contraction of the connecting copper bar 3 , the width of the connecting copper bar 3 is equal to or smaller than the width of the busbar copper bar 2 .

[0043] It should be noted that the adjacent functional module 10 in this embodiment refers to the functional module 10 located on the left side of the functional module 10. When making an electrical connection, the connecting copper bar 3 of the functional module 10 located on the left extends out of its busbar copper bar embedding groove 101, and the extending part extends into the busbar copper bar embedding groove 101 of the functional module 10, and is tightened and connected to the busbar copper bar 2 described herein through the second electrical connection screw 8, thereby realizing the electrical connection between the functional module 10 and the functional module 10 on the left.

[0044] As for the electrical connection method between the present functional module 10 and the functional module 10 on the right, the connecting copper bar 3 of the present functional module 10 extends out of the busbar copper bar embedding groove 101 of the present functional module 10 and is tightened by the first electrical connection screw 7, and the extending part extends into the busbar copper bar embedding groove 101 of the right functional module 10, and is tightened and connected to the busbar copper bar 2 by the second electrical connection screw 8 of the right functional module 10, thereby realizing the electrical connection between the present functional module 10 and the right functional module 10.

[0045] like Figure 2 As shown, the connecting copper bar 3 includes a U-shaped groove 301 opened at the end, and a waist-shaped groove 302 coaxial with the U-shaped groove 301; the U-shaped groove 302 is used to be screwed with the second electrical connection screw 8 of the adjacent functional module 10, and the waist-shaped groove 302 is used for the first electrical connection screw 7 to be screwed.

[0046] like Figure 6 As shown, specifically, in this embodiment, when the connecting copper bar 3 is switched from the extended state to the retracted and hidden state, it is only necessary to reversely rotate the first electrical connection screw 7 to slightly lift it, thereby releasing the force applied to the connecting copper bar 3 against the busbar copper bar 2, and manually move the connecting copper bar 3 toward the second electrical connection end 103. At this time, the first electrical connection screw 7 will gradually move toward the waist-shaped groove 302 and one end of the U-shaped groove 301 as the connecting copper bar 3 moves. After the connecting copper bar 3 completely enters the current copper bar embedding groove 101, tighten the first electrical connection screw 7 to achieve mutual fastening of the connecting copper bar 3 and the busbar copper bar 2. At this time, the connecting copper bar 3 is in a retracted and hidden state. Figure 5 shown.

[0047] When the connecting copper bar 3 switches from the retracted and hidden state to the extended state, it is only necessary to reversely rotate the first electrical connection screw 7 to slightly lift it, thereby releasing the force applied to the connecting copper bar 3 against the busbar copper bar 2. The connecting copper bar 3 is manually moved toward the first electrical connection end 102. At this time, the first electrical connection screw 7 will gradually move toward the end of the waist-shaped groove 302 close to the second electrical connection end 103 as the connecting copper bar 3 moves. After the connecting copper bar 3 extends out of the busbar copper bar embedding groove 101, tighten the first electrical connection screw 7 to fasten the connecting copper bar 3 and the busbar copper bar 2 to each other. At this time, the connecting copper bar 3 is in an extended state, such as Figure 4 As shown, in this state, it is used for electrical connection with the functional module 10 located on the right.

[0048] As an optimization of this organization, Figure 2 As shown, a first plug-in board slot 104 capable of receiving a first plug-in board 5 is provided at the first electrical connection end 102 ; correspondingly, a second plug-in board slot 105 capable of receiving a second plug-in board 6 is provided at the second electrical connection end 103 .

[0049] In this embodiment, when the first electrical connection end 102 and the second electrical connection end 103 are in a non-use state, the first plug-in board slot 104 is plugged in through the first plug-in board 5, and the second plug-in board slot 105 is plugged in through the second plug-in board 6, thereby achieving effective sealing of both ends of the busbar copper bar embedding groove 101 to prevent external foreign matter from entering.

[0050] In addition, a third plug-in board slot 106 for the first plug-in board 5 to be plugged into is provided at a position adjacent to the first plug-in board slot 104. When the connecting copper bar 3 is extended, the first plug-in board 5 is plugged into the third plug-in board slot 106 to block the rear end of the connecting copper bar 3. This structure can effectively prevent the connecting copper bar 3 from shrinking when it is extended to be electrically connected to the functional module 10 on the right, thereby facilitating the stable electrical connection.

[0051] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
