Description

Technical Field

[0001] This invention relates to the field of line connection device technology, specifically to a connection and separation automatic alarm connector. Background Technology

[0002] Connectors, as quick-connect components that can connect two or more active devices, are often used in current or signal transmission lines and play an important role in the stable transmission of signals. In actual use, especially in signal transmission between two or more large active devices, the number of connectors used is large due to the large number of transmission lines.

[0003] Existing connectors mostly use friction or snap-fit ​​connections, which leads to a decrease in connection strength due to wear during repeated quick-connection use. Under complex working conditions, they are prone to loosening or falling off, resulting in signal transmission failure or device malfunction. Furthermore, the large number of connectors used during inspection and maintenance makes it difficult for personnel to quickly and accurately locate loose or detached connectors, which is not only time-consuming and labor-intensive but also inefficient.

[0004] Therefore, there is an urgent need for a connector with automatic alarm function to solve the defects of the existing connectors in actual use. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] This invention provides an automatic alarm connector for connection and separation, which effectively enhances the durability and connection strength of the connector during use, making it less prone to loosening or detachment. It also provides a timely alarm to alert maintenance personnel when loosening or detachment occurs. This invention solves the problems of existing connectors, which often use friction or snap-fit ​​connections, leading to decreased connection strength due to wear after repeated quick-connection use. These connectors are also prone to loosening or detachment under complex operating conditions, resulting in signal transmission failure or device malfunction. Furthermore, the large number of connectors used during inspection and maintenance makes it difficult for personnel to quickly and accurately locate loose or detached connectors, resulting in wasted time, effort, and low efficiency.

[0007] (II) Technical Solution

[0008] This invention provides the following technical solution: an automatic alarm connector for connection and separation, comprising wire I and wire II. One end of wire I is fixedly mounted with a first connecting post, and one end of wire II is fixedly mounted with a second connecting post. A limiting sleeve is fixedly sleeved on the left side of the inner cavity of the first connecting post, and a movable sleeve is movably sleeved on the right side of the inner cavity of the first connecting post. The right end of the movable sleeve and the end face on the right side of the inner cavity of the first connecting post are connected by a pressure spring to form a transmission connection. Three transmission balls arranged in a ring array are movably sleeved between the end faces opposite to the limiting sleeve and the movable sleeve. The inner cavity of the second connecting post is provided with a protruding conductor that is fixedly connected to the inside of wire II, and a retaining ring is provided on one side of the outer surface of the conductor. When wire I and wire II are connected, the transmission balls on the first connecting post are engaged in the retaining ring on the second connecting post.

[0009] Preferably, the end faces of the limiting bushing and the movable bushing are both inclined, and their cross-sections when they are joined have an inverted "V" shape, and radial linear tracks are provided on their inclined surfaces.

[0010] Preferably, the limiting bushing has a first conductive post extending to its right end face inside, and a buzzer is fixedly installed on the outer surface of the first connecting post to form a conductive connection with the first conductive post. The limiting bushing has a conductive block inside, and the transmission ball at the position corresponding to the conductive block is made of metal, so that the transmission ball can form a circuit connection with the wire I through the conductive block.

[0011] Preferably, the movable bushing has a second conductive post extending to its left end face inside, and a set of power supplies is provided on the movable bushing to form a circuit connection with the second conductive post. Furthermore, two sets of circuits are provided in both the first and second conductive posts, so that when the first and second conductive posts come into contact, a series circuit can be formed between the power supply and the buzzer.

[0012] Preferably, one of the other two transmission balls is a pressure ball with an internal pressure-sensitive resistor, and is electrically connected to an alarm fixedly installed inside the first connecting column. The pressure ball, the alarm and the power supply fixedly installed on the movable bushing form a series circuit, and a parallel circuit is formed with the buzzer. Thus, the pressure change on the pressure ball can be used to determine whether the wire I and the wire II are loose, effectively preventing poor contact between them.

[0013] Preferably, a control circuit is provided between the pressure ball and the alarm, and a pressure threshold is set on it. After the first connecting post and the second connecting post are engaged with each other, if the pressure on the pressure ball is greater than the pressure threshold set on the control circuit, it indicates that the connector is loose and the alarm is triggered; if the pressure on the pressure ball is less than the pressure threshold set on the control circuit, it indicates that the connector is not loose and the alarm is in a normally closed state.

[0014] (III) Beneficial Effects

[0015] The present invention has the following beneficial effects:

[0016] 1. This automatic alarm connector for connection separation, regarding the setting of the limiting bushing, the movable bushing and its structure, when the first connecting post and the second connecting post are locked together, the transmission ball on the first connecting post, while locking the second connecting post, can drive the movable bushing to move to the right and compress the pressure spring, thereby causing the second conductive post on it and the first conductive post on the limiting bushing to be misaligned. Compared with the existing technology, while enhancing the connection strength of the connector, the current or signal between the connecting wire I and the wire II is connected under the action of the conductive ball on the transmission ball and the conductive block in the limiting bushing. When the first connecting post and the second connecting post are disengaged, the elastic force of the pressure spring causes the second conductive post and the first conductive post to make contact again to conduct electricity to connect the buzzer. Thus, when the connector is disengaged, an audible and visual alarm can be issued to remind the inspection and maintenance personnel.

[0017] 2. This automatic alarm connector features a varistor and its circuit connection inside one of the transmission balls. By detecting and feeding back the pressure change of the pressure ball on that ball, it can determine whether there is any looseness between the first and second connecting posts and remind maintenance personnel to carry out repairs. This effectively avoids the problem of poor current or signal transmission quality caused by poor contact that cannot be detected during the use of the connector. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 An automatic alarm connector for connection and separation includes wire I1 and wire II2. One end of wire I1 and wire II2 are respectively fixedly connected to an active device. A first connecting post 3 is fixedly installed at one end of wire I1, and a second connecting post 8 is fixedly installed at one end of wire II2. The first connecting post 3 and the second connecting post 8 are fixedly connected to two sets of active devices by a snap-fit ​​method, and current or signal transmission is performed. Figure 2 As shown, a limiting sleeve 4 is fixedly sleeved on the left side of the inner cavity of the first connecting column 3, and a movable sleeve 5 is movably sleeved on the right side of the inner cavity of the first connecting column 3. The right end of the movable sleeve 5 and the end face of the right side of the inner cavity of the first connecting column 3 are connected by a pressure spring 6. The pressure spring 6 is always in a compressed state. Three transmission balls 7 arranged in a ring array are movably sleeved between the opposite end faces of the limiting sleeve 4 and the movable sleeve 5.

[0027] like Figure 3 As shown, the inner cavity of the second connecting post 8 is provided with an extended conductor that is fixedly connected to the inside of the wire II 2. On one side of the outer surface of the conductor, there is a retaining ring 9 with an arc-shaped cross-section. When the wire I 1 and the wire II 2 are connected, the transmission ball 7 on the first connecting post 3 is engaged in the retaining ring 9 on the second connecting post 8. Then, under the elastic force of the pressure spring 6, the three transmission balls 7 arranged in a ring array can be subjected to inward pressure, so that the connection strength between the wire I 1 and the wire II 2 is high and it is not easy for loosening or falling off to occur.

[0028] like Figure 4As shown, in this technical solution, the end faces of the limiting bushing 4 and the movable bushing 5 are both inclined, and their cross-sections when they are combined form an inverted "V" shape. Radial linear tracks are provided on their inclined surfaces. When the three transmission balls 7 arranged in a ring array on them are subjected to outward pressure, the movable bushing 5 can be forced to move to the right and compress the pressure spring 6.

[0029] Example 1

[0030] like Figure 2 and Figure 6 As shown, in this technical solution, the limiting bushing 4 has a first conductive post 10 extending to its right end face inside, and a buzzer 12 is fixedly installed on the outer surface of the first connecting post 3 to form a conductive connection with the first conductive post 10. The limiting bushing 4 has a conductive block inside, and the transmission ball 7 at the position corresponding to the conductive block is made of a conductive ball of metal with high conductivity, so that the transmission ball 7 can form a circuit connection with the wire I1 through the conductive block.

[0031] like Figure 2 , Figure 5 and Figure 6 As shown, in this technical solution, the movable bushing 5 has a second conductive post 11 extending to its left end face inside, and a set of power supply is provided on the movable bushing 5 to form a circuit connection with the second conductive post 11. In addition, two sets of circuits are provided in both the first conductive post 10 and the second conductive post 11. Thus, when the first conductive post 10 and the second conductive post 11 come into contact, a series circuit can be formed between the power supply and the buzzer 12.

[0032] Example 2

[0033] like Figure 6 As shown, in this technical solution, one of the other two transmission balls 7 is a pressure ball with an internal pressure-sensitive resistor, and is electrically connected to the alarm fixedly installed inside the first connecting column 3. The pressure ball, the alarm and the power supply fixedly installed on the movable bushing 5 form a series circuit, and form a parallel circuit with the buzzer 12. Thus, the pressure change on the pressure ball can be used to determine whether the wire I1 and the wire II2 are loose, effectively preventing poor contact between them.

[0034] In this technical solution, a control circuit is provided between the pressure ball and the alarm, and a pressure threshold is set on it. After the first connecting post 3 and the second connecting post 8 are engaged with each other, if the pressure on the pressure ball is greater than the pressure threshold set on the control circuit, it indicates that the connector is loose and the alarm is triggered; if the pressure on the pressure ball is less than the pressure threshold set on the control circuit, it indicates that the connector is not loose and the alarm is in a normally closed state.

[0035] The usage method and working principle of this embodiment are as follows:

[0036] When it is necessary to connect wire I1 and wire II2, the first connecting post 3 and the second connecting post 8 are used to clamp and fix them together. Under the action of the second connecting post 8, the transmission ball 7 on the first connecting post 3 is squeezed outward, and the movable bushing 5 is forced to move to the right to compress the pressure spring 6 until the transmission ball 7 is clamped in the retaining ring 9 on the second connecting post 8. Then, under the action of a group of conductive balls and conductive blocks in the transmission ball 7, the wire I1 and wire II2 and their active devices are connected to achieve current or signal connection. At the same time, under the squeezing action of the retaining ring 9, the connection strength between the first connecting post 3 and the second connecting post 8 can be strengthened, and the first conductive post 10 on the limiting bushing 4 and the second conductive post 11 on the movable bushing 5 can be disconnected from each other, thereby cutting off the conductive connection to the buzzer 12 and putting it in the closed state.

[0037] When the first connecting post 3 and the second connecting post 8 fall off due to pulling during use, the transmission ball 7 on the first connecting post 3 is no longer squeezed by the second connecting post 8. Under the elastic force of the pressure spring 6, the movable bushing 5 moves to the left, causing the second conductive post 11 on it to make contact with the first conductive post 10 on the limiting bushing 4 again. This connects the buzzer 12 on the first connecting post 3 to emit an audible and visual alarm to remind the inspection and maintenance personnel, thus achieving the purpose of automatic alarm for the connector falling off.
