Description

Technical Field

[0001] This utility model relates to the field of electrical contacts, and in particular to an easy-to-install electrical contact. Background Technology

[0002] Electrical contacts refer to electrical contact connections between two conductors that can separate, make, or slide due to relative movement during operation. Auxiliary contacts are a type of electrical contact, used in AC 50Hz and DC control circuits. As a functional module of contactors or circuit breakers, they realize the switching of the main circuit through remote control and are widely used in signal transmission, interlocking protection, and other scenarios in industrial power distribution systems. However, traditional auxiliary contacts cannot speed up installation efficiency while ensuring installation stability when installed with contactors. Most are fixed with bolts. Although there are now methods that first clamp and then use a single spring for locking, this installation method has significant safety hazards. The single locking method is prone to slippage and reduces the stability of the connection.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes an easy-to-install electrical contact, which solves the aforementioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: an easy-to-install electrical contact includes an auxiliary contact. A fixing base is fixed to both sides of the front and back of the auxiliary contact. An auxiliary frame is fixed to the fixing base. A contactor is attached to the bottom of the auxiliary contact. Positioning plates are fixed to the four sides of the bottom of the auxiliary contact and below the fixing base. Positioning frames for inserting the positioning plates are fixed to the four sides of the top of the contactor. Anti-detachment components are provided on the fixing base and auxiliary frame to cooperate with the positioning plates and positioning frames.

[0006] The present invention provides an easy-to-install electrical contact as described above, further comprising: the anti-disengagement component including a vertical plate rotatably mounted in a fixed base via a horizontal axis; a locking insert plate fixed to the bottom of the vertical plate near the auxiliary contact; a first groove provided on the side of the two sets of positioning frames that are far apart from each other; a second groove adapted to the first groove provided on each set of positioning plates; one end of the locking insert plate passing through the first groove and engaging with the top of the inner cavity of the second groove; a T-shaped positioning rod inserted on each set of auxiliary frames; a pressure block fixed to the bottom end of the T-shaped positioning rod, with the front and back of the pressure block abutting against the side of the inner cavity of the vertical plate and the fixed base that are close to each other; a first spring wound around each set of T-shaped positioning rods; the two ends of the first spring fixed to the top square plate of the T-shaped positioning rod and the auxiliary frame; and an anti-sway structure provided below the locking insert plate.

[0007] The present invention provides an easy-to-install electrical contact as described above, further comprising: an anti-sway structure including a push block slidably disposed at the bottom of a locking plate; a second spring fixed on the side of the vertical plate and the push block that are close to each other; and the side of the push block that is away from the second spring being engaged in a first groove and a second groove.

[0008] The present invention provides an easy-to-install electrical contact as described above, further comprising: a limiting slide is provided at the bottom of the locking plate and the top of the push block is slidably disposed within the limiting slide, and the top of each set of push blocks has a T-shaped structure.

[0009] The present invention provides an easy-to-install electrical contact as described above, further comprising: a side pull plate fixed on the side of the left and right sets of push blocks that are far apart from each other.

[0010] The present invention provides an easy-to-install electrical contact as described above, further comprising: the height between the pressure block and the top of the auxiliary frame cavity is greater than the height of the pressure block.

[0011] The present invention provides an easy-to-install electrical contact as described above, further comprising: a gap between one end of the locking plate located in the second groove and the inner side of the second groove cavity; and a gap between the bottom of the locking plate and the bottom of both the first and second groove cavities.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting an anti-detachment component and adopting a quick-locking positioning method with multiple self-locking structures, can quickly fix the bottom of the auxiliary contact to the contactor. The entire assembly process is fully interlocked, which speeds up the installation efficiency while ensuring installation stability. It effectively avoids the problem that a single locking method can easily cause the auxiliary contact to detach from the contactor. This not only makes the installation of the auxiliary contact more convenient, but also improves the assembly stability.

[0014] 2. This utility model, by setting a limiting slide and cooperating with a push block with a T-shaped structure at the top, can limit the sliding of the push block, preventing the push block from easily disengaging from the locking plate and affecting the normal locking and positioning of the push block on the locking plate.

[0015] 3. By providing a side pull plate, this utility model facilitates the user's movement of the push block, thereby quickly and easily releasing the push block from the locking plate, so as to assist the locking plate in separating from the first and second grooves.

[0016] 4. This utility model sets a height difference so that the pressure block can move stably upward and separate from the vertical plate, avoiding interference with the normal swing of the vertical plate when it is necessary to unlock.

[0017] 5. By setting the spacing, this utility model allows the vertical plate to drive the locking plate to swing stably without colliding with the first or second groove, thus improving the stability of the component during operation. Attached Figure Description

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0025] An easy-to-install electrical contact includes an auxiliary contact 1. Fixing seats 6 are fixed to both sides of the front and back of the auxiliary contact 1. An auxiliary frame 7 is fixed to the fixing seats 6. A contactor 2 is attached to the bottom of the auxiliary contact 1. Positioning plates 3 are fixed to the four sides of the bottom of the auxiliary contact 1, below the fixing seats 6. Positioning frames 4 for inserting the positioning plates 3 are fixed to the four sides of the top of the contactor 2. Anti-disengagement components are provided on the fixing seats 6 and auxiliary frames 7 to cooperate with the positioning plates 3 and positioning frames 4. The anti-disengagement components include a vertical plate 8 rotatably mounted in the fixing seats 6 via a horizontal axis. A locking insert 16 is fixed to the bottom of the vertical plate 8 near the auxiliary contact 1. A first groove 5 is provided on the side of the two sets of positioning frames 4 that are far apart from each other. Each set of positioning plates 3 has a groove adapted to the first groove 5. The second groove 14, one end of the locking plate 16 passes through the first groove 5 and is engaged with the top of the inner cavity of the second groove 14. Each set of auxiliary frames 7 is equipped with a T-shaped positioning rod 9. The bottom end of the T-shaped positioning rod 9 is fixed with a pressure block 10, and the front and back of the pressure block 10 are close to each other on the inner side of the vertical plate 8 and the fixed seat 6. Each set of T-shaped positioning rods 9 is wound with a first spring 11. The two ends of the first spring 11 are fixed to the top square plate of the T-shaped positioning rod 9 and the auxiliary frame 7. An anti-sway structure is provided below the locking plate 16. The anti-sway structure includes a push block 12 that is slidably disposed at the bottom of the locking plate 16. A second spring 13 is fixed on the side of the vertical plate 8 and the push block 12 that are close to each other. The side of the push block 12 away from the second spring 13 is engaged in the first groove 5 and the second groove 14.

[0026] Specifically, this utility model, by setting an anti-disengagement component, utilizes the elastic rebound of the first spring 11 to quickly push the pressure block 10 into the gap between the vertical plate 8 and the fixed base 6, positioning the vertical plate 8 and the locking plate 16. Furthermore, the anti-sway structure design, utilizing the pushing force of the second spring 13, causes the push block 12 to engage in the first groove 5 and the second groove 14, providing secondary locking and positioning of the locking plate 16 to prevent disengagement. At this time, the quick-locking positioning method with multiple self-locking structures can quickly fix the bottom perimeter of the auxiliary contact 1 onto the contactor 2. The entire assembly process involves locking, ensuring installation stability while accelerating installation efficiency. This effectively avoids the risk of the auxiliary contact 1 and contactor 2 disengaging with a single locking method, making the installation of the auxiliary contact 1 more convenient and simultaneously improving assembly stability.

[0027] The bottom of the locking plate 16 is provided with a limiting slide 15 and the top of the push block 12 is slidably disposed in the limiting slide 15. The top of each push block 12 has a T-shaped structure.

[0028] Specifically, by utilizing the sliding connection between the limiting slide 15 and the push block 12, the push block 12 can be slidably limited, which improves the stability of the push block 12 when it moves and prevents it from easily disengaging from the locking plate 16, thus affecting the normal locking and positioning of the push block 12 on the locking plate 16.

[0029] Side pull plates are fixed on the side of the two sets of push blocks 12 that are far apart from each other.

[0030] Specifically, the design of the side pull plate can assist in moving the push block 12, so as to quickly release the locking state of the push block 12 on the locking plate 16, and thus assist the locking plate 16 in separating from the first groove 5 and the second groove 14.

[0031] The height between the top of the inner cavity of the pressure block 10 and the auxiliary frame 7 is greater than the height of the pressure block 10.

[0032] Specifically, the height difference is designed to provide sufficient upward space for the pressure block 10 so that it can move upward stably and separate from the vertical plate 8, avoiding interference with the normal swinging of the vertical plate 8 when it is necessary to unlock.

[0033] There is a gap between the end of the locking plate 16 located in the second groove 14 and the inner side of the inner cavity of the second groove 14, and there is a gap between the bottom of the locking plate 16 and the bottom of the first groove 5 and the inner cavity of the second groove 14.

[0034] Specifically, the spacing is designed so that the vertical plate 8 can drive the locking plate 16 to swing stably without colliding with the first groove 5 or the second groove 14.

[0035] The specific usage process is as follows: In the initial state, the vertical plate 8 is in an outward swing state, and the pressure block 10 is at the top of one end of the vertical plate 8. At this time, the user contacts the auxiliary contact 1 with the contactor 2. At the same time, the positioning plate 3 is pre-inserted into the positioning frame 4. Then, the user presses down on the vertical plate 8, thereby causing its top end to swing upward and pushing the pressure block 10 upward, stretching the first spring 11 until the vertical plate 8 drives the locking plate 16 into the first groove 5 and locks it into the second groove 14. At this time, the vertical plate 8 is exactly in a vertical state. At this time, the elastic rebound of the first spring 11 can drive the pressure block 10 to move downward and lock it in the gap between the vertical plate 8 and the fixed base 6, limiting the position of the vertical plate 8 and the locking plate 16. At this time, the locking plate 16 can be used to lock the auxiliary contact 1. When the locking plate 16 enters the first groove 5, the push block 12 will pre-contact the positioning frame 4 and move outward with the swing of the locking plate 16, compressing the second spring 13. When the vertical plate 8 is in a vertical state, the locking plate 16 is parallel to the bottom of the first groove 5 and the second groove 14. At this time, the elastic rebound of the second spring 13 can drive the push block 12 to move inward quickly and lock into the first groove 5 and the second groove 14, locking the locking plate 16 and preventing it from easily shifting. The quick-locking positioning method with multiple self-locking structures can stably and quickly fix the auxiliary contact 1 on the contactor 2. This utility model, by setting an anti-disengagement component, can quickly lock the auxiliary contact 1 on the contactor 2 by utilizing the elastic rebound of the first spring 11. The push block 10 is quickly engaged in the gap between the vertical plate 8 and the fixed base 6 to position the vertical plate 8 and the locking plate 16. The anti-sway structure design, utilizing the pushing force of the second spring 13, causes the push block 12 to engage in the first groove 5 and the second groove 14, providing secondary locking and positioning of the locking plate 16 to prevent disengagement. At this time, a quick-engagement positioning method with multiple self-locking structures is used to quickly fix the bottom perimeter of the auxiliary contact 1 to the contactor 2. The entire assembly process involves engagement, ensuring installation stability while accelerating installation efficiency. This effectively avoids the risk of disengagement between the auxiliary contact 1 and the contactor 2 caused by a single locking method, making the installation of the auxiliary contact 1 more convenient and simultaneously improving assembly stability. The limit slide 15 and the push block 10 are used to further enhance the stability of the assembly. The sliding connection of block 12 can limit the sliding of push block 12, improving the stability of push block 12 during movement and preventing it from easily detaching from locking plate 16, thus affecting the normal locking and positioning of push block 12 on locking plate 16. The design of the side pull plate can assist in moving push block 12, making it convenient to quickly release the locking state of push block 12 on locking plate 16, so as to assist locking plate 16 in separating from first groove 5 and second groove 14. The height difference design provides sufficient upward space for pressure block 10, so that pressure block 10 can move upward stably and detach from vertical plate 8, avoiding interference with the normal swing of vertical plate 8 when unlocking is required. The spacing design allows vertical plate 8 to drive locking plate 16 to swing stably without colliding with first groove 5 or second groove 14.

The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
