Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and more specifically to a contact finger and contact base connection device for disconnecting switches. Background Technology

[0002] In electrical equipment, connecting devices are often used to connect the contact fingers and the contact base. While ensuring a stable connection, it is also necessary to ensure safety and other factors. If the contact fingers are too tight, it will be difficult for the contact fingers to be inserted into the contact base. If the contact fingers are not tight enough, the contact fingers and the contact base will easily separate.

[0003] The prior art discloses a ring-shaped contact finger connection device that is easy to maintain and repair. Through the setting of the locking mechanism, the contact finger and the contact finger seat are fixed during the use of the device, making the connection more convenient and ensuring the basic stability of the electrical connection. However, this utility model also has the following problems: the spring is always in a state of excessive tension. It can squeeze the locking block to lock in the slot to achieve effective fixation of the contact finger, but when the contact finger is inserted or removed, it is difficult to remove it directly, which will cause deformation and damage to the locking block and the spring. Removing it by opening the ring wall is very inconvenient. Therefore, this utility model proposes a contact finger and contact seat connection device for disconnecting switches. Utility Model Content

[0004] The purpose of this utility model is to provide a contact finger and contact base connection device for disconnecting switches, which provides a firm connection between the contact fingers and contact base and facilitates easy connection and separation of the contact fingers and contact base.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A contact finger and contact base connecting device for a disconnecting switch includes a contact base and a contact finger engaged on one side of the contact base. The contact base is composed of a first semicircular base and a second semicircular base. The first semicircular base and the second semicircular base are fixedly connected on one side by a fixing part and rotatably connected on the other side by a rotating part. Connecting parts are provided on both sides of the contact base. Each connecting part includes a locking block and a high-elasticity spring. An inner groove is provided on both sides of the contact base, and a base plate is provided within the inner groove. A locking block is provided on the side of the base plate near the contact finger. The locking block is fixedly engaged with the base plate. A high-elasticity spring is provided. A rotating post is rotatably connected to the side of the base plate away from the contact finger. The rotating post has a threaded surface on its outer side. The side of the rotating post away from the base plate passes through the corresponding contact seat and is threadedly connected to the contact seat. Inclined surfaces are provided on both sides of the locking block. The contact finger has a locking groove corresponding to the position of the locking block. The locking block is locked in the corresponding locking groove. Threaded posts are inserted into the sides of the semicircular base one and the semicircular base two away from the contact finger through threaded connections. The diameter of the threaded post on the side closer to the contact finger is smaller than the diameter on the side away from the contact finger.

[0007] By adopting the above technical solution, this utility model has the following advantages:

[0008] The design of the semi-circular base 1, semi-circular base 2, fixing part, and rotating part of this utility model allows the contact base to be opened, facilitating subsequent maintenance within the contact base. The high-elasticity spring and locking block of this utility model allow the high-elasticity spring to push the locking block into the locking groove, strengthening the connection between the contact finger and the contact base and effectively preventing separation. The base plate and rotating column of this utility model allow the base plate to move downwards when the contact finger needs to be fixed, thereby increasing the tightness of the high-elasticity spring and causing the locking block to abut against the locking groove, ensuring a firm connection between the contact finger and the contact base. When the contact finger needs to be removed or inserted, the base plate can be moved upwards by the rotating column, reducing the tightness of the high-elasticity spring. When the locking block is pressed by the contact finger, it can compress the high-elasticity spring to move into the embedded groove, facilitating the connection and separation of the contact finger and the contact base. The threaded column of this utility model allows it to gradually screw into the contact, further compressing the contact finger and the contact base into tight contact.

[0009] Furthermore, the fixing part includes a fixing plate, one side of which is fixedly connected to one side of the corresponding semicircular seat one and the semicircular seat two, and the fixing plate and the fixing plate are fixedly connected by a number of bolts.

[0010] By adopting the above technical solution, this utility model has the following advantages:

[0011] The fixing plate of this utility model serves to fix the first semicircular seat and the second semicircular seat, and also facilitates the subsequent separation of the first semicircular seat and the second semicircular seat, thereby facilitating the subsequent maintenance of the contact seat.

[0012] Furthermore, the rotating part includes a side plate, an inner plate, and a rotating shaft. The two ends of the semicircular seat one away from the fixed plate are both fixedly provided with side plates, and the two semicircular seats two away from the fixed plate are fixedly provided with an inner plate. The inner plate is located between the side plates, and the rotating shaft is fixedly provided at both ends of the inner plate. The rotating shaft is rotatably connected to the corresponding side plate.

[0013] By adopting the above technical solution, this utility model has the following advantages:

[0014] The side plate, inner plate, and rotating shaft of this utility model allow the contact seat to be opened for easy maintenance, and also serve to connect the first semicircular seat and the second semicircular seat.

[0015] Furthermore, the rotating column passes through the corresponding contact seat and is fixedly connected to the horizontal column.

[0016] By adopting the above technical solution, this utility model has the following advantages:

[0017] The horizontal column in this invention facilitates the rotation of the rotating column.

[0018] Furthermore, both ends of the embedded groove are provided with sliding grooves, and both ends of the base plate and the two ends of the card block near the high-elastic spring are fixedly provided with sliders, which are movably connected and locked in the corresponding sliding grooves.

[0019] By adopting the above technical solution, this utility model has the following advantages:

[0020] The design of the groove and slider in this invention ensures that the rotation of the rotating column will not cause the base plate to rotate, and the locking block will not disengage from the inner groove.

[0021] Furthermore, the contact seat is provided with several annular grooves, each of which is provided with a spring contact finger, and the cross-section of the annular groove is trapezoidal.

[0022] By adopting the above technical solution, this utility model has the following advantages:

[0023] The trapezoidal shape of this invention allows the spring contact finger to make close contact with the contact finger and the contact seat. Attached Figure Description

[0030] like Figures 1 to 2As shown in this specific embodiment, a contact finger and contact seat connecting device for a disconnecting switch includes a contact seat and a contact finger 1 locked onto one side of the contact seat. The contact seat is composed of a semi-circular seat 3 and a semi-circular seat 2. The semi-circular seat 3 and the semi-circular seat 2 are fixedly connected on one side by a fixing part and rotatably connected on the other side by a rotating part. Both sides of the contact seat are provided with connecting parts, each including a locking block 6 and a high-elasticity spring 14. Both sides of the contact seat are provided with an inner groove 4, and a base plate 13 is provided in the inner groove 4. The side of the base plate 13 closest to the contact finger 1 is provided with a locking block 6, and the locking block 6 is fixedly connected to the base plate 13. A high-elasticity spring 14 is fixedly provided. A rotating post 5 is rotatably connected to the side of the base plate 13 away from the contact finger 1. The rotating post 5 has a threaded surface on its outside. The side of the rotating post 5 away from the base plate 13 passes through the corresponding contact seat and is threadedly connected to the contact seat. Both sides of the locking block 6 have inclined surfaces 601. The contact finger 1 has a locking groove 101 at the position of the locking block 6. The locking block 6 is locked in the corresponding locking groove 101. The side of the semicircular seat 1 3 and the semicircular seat 2 away from the contact finger 1 is threadedly connected to a threaded post 10. The diameter of the threaded post 10 on the side closer to the contact finger 1 is smaller than the diameter on the side away from the contact finger 1.

[0031] Through the above configuration, the semicircular base 3, semicircular base 2, fixing part, and rotating part of this utility model allow the contact base to be opened, facilitating subsequent maintenance inside the contact base. The high-elasticity spring 14 and the locking block 6 allow the high-elasticity spring 14 to push the locking block 6 into the locking groove 101, strengthening the connection between the contact finger 1 and the contact base and effectively preventing separation. The base plate 13 and the rotating column 5 allow the base plate 13 to be moved downwards by rotating the rotating column 5 when it is necessary to fix the contact finger 1. This increases the tightness of the high-elasticity spring 14, causing the locking block 6 to abut against the locking groove 101, and the contact finger 1 to be firmly connected to the contact seat. When it is necessary to remove or insert the contact finger 1, the base plate 13 can be moved upward by the rotating column 5 to reduce the tightness of the high-elasticity spring 14. When the locking block 6 is squeezed by the contact finger 1, it can squeeze the high-elasticity spring 14 to move into the inner groove 4, which facilitates the connection and separation of the contact finger 1 and the contact seat. The setting of the threaded column 10 of this utility model can further squeeze the contact finger 1 and the contact seat to make tight contact when it is gradually screwed in.

[0032] For example, 3 to Figure 4 As shown, the fixing part includes a fixing plate 11, one side of which is fixedly connected to one side of the corresponding semicircular seat 1 3 and semicircular seat 2. The fixing plate 11 is fixedly connected to the fixing plate 2 by several bolts. The rotating part includes a side plate 12, an inner plate 7 and a rotating shaft 701. The side plate 12 is fixedly provided at both ends of the side of the semicircular seat 1 3 away from the fixing plate 11. The inner plate 7 is fixedly provided at the side of the semicircular seat 2 away from the fixing plate 11. The inner plate 7 is located between the side plates 12. The rotating shaft 701 is fixedly provided at both ends of the inner plate 7. The rotating shaft 701 is rotatably connected to the corresponding side plate 12.

[0033] With the above configuration, the fixing plate 11 of this utility model serves to fix the semicircular seat 3 and the semicircular seat 2, and also facilitates the subsequent separation of the semicircular seat 3 and the semicircular seat 2, thereby facilitating the subsequent maintenance of the contact seat; the side plate 12, inner plate 7 and rotating shaft 701 of this utility model allow the contact seat to be opened for easy maintenance, and also serve to connect the semicircular seat 3 and the semicircular seat 2.

[0034] like Figures 1 to 3 As shown, the rotating column 5 passes through the corresponding contact seat and is fixedly connected to the horizontal column 501; both ends of the embedded groove 4 are provided with sliding grooves 401; both ends of the base plate 13 and both ends of the block 6 near the high-elastic spring 14 are fixedly provided with sliders 15, which are movably connected and locked in the corresponding sliding grooves 401; the contact seat is provided with several annular grooves 9, and each annular groove 9 is provided with a spring contact finger 8; the cross section of the annular groove 9 is trapezoidal.

[0035] With the above settings, the horizontal column 501 of this utility model facilitates the rotation of the rotating column 5; the sliding groove 401 and the slider 15 of this utility model ensure that the rotation of the rotating column 5 will not cause the base plate 13 to rotate, and the locking block 6 will not disengage from the inner groove 4; the trapezoidal shape of this utility model allows the spring contact finger 8 to be in close contact with the contact finger 1 and the contact seat.

[0036] Working principle: When the contact finger 1 is inserted, the base plate 13 abuts against the bottom end of the inner groove 4, and the high-elasticity spring 14 is in a state of low tension. When the contact finger 1 is inserted, the contact finger 1 will gradually push the inclined surface 601 to squeeze the locking block 6 into the inner groove 4. After the contact finger 1 is pushed into place, the elastic force of the high-elasticity spring 14 will squeeze the locking block 6 into the locking slot 101. Then, the horizontal column 501 is rotated to drive the rotating column 5 to rotate, thereby driving the base plate 13 to press against the high-elasticity spring 14, which increases the tension of the high-elasticity spring 14, thus making it difficult for the locking block 6 to be locked. The movable contact finger 1 and the contact seat are effectively connected, which can effectively prevent them from separating. Then, the threaded post 10 is screwed in, and the threaded post 10 gradually squeezes the contact finger 1 towards the contact seat, thereby improving the connection strength between the contact finger 1 and the contact seat. When it is necessary to remove the contact finger 1, simply rotate the horizontal post 501 to return the base plate 13 to its original position. At this time, the high-elasticity spring 14 is in a state of low tension, which facilitates the removal of the contact finger 1. When the contact seat is maintained, the bolts of the fixing plate 11 can be opened to open the contact seat, which is divided into semi-circular seat 1 3 and semi-circular seat 2.

[0037] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
