Description

Technical Field

[0002] Connectors are widely used components in the fields of electronics, electrical engineering, mechanics, etc. They are used to connect two or more devices, circuits or systems to achieve the transmission and interaction of signals, currents, energy, etc. With the development of the electronics industry, the integration of circuits is getting higher and higher, and circuit design is gradually becoming modular. Reliable and stable connections between circuit boards are becoming more and more important.

[0003] Prior art such as the Chinese patent "CN111092324A" provides a connector, which belongs to the field of connector technology. The connector of the present invention includes a connector housing and a contact component. The connector housing includes a housing side panel with a snap-in window, and an elastic cantilever arm is provided on the housing side panel. Each elastic cantilever arm is provided with the snap-in window. The contact component includes a mounting base and a contact piece, and the contact piece is fixed on the mounting base. A spring key is provided on the mounting base, and a card block is provided on the spring key. In the process of assembling the connector of the present invention, the contact component can be smoothly inserted into the connector housing. Because both the elastic cantilever arm and the spring key can undergo elastic deformation, the maximum deformation amount of the spring key is relatively low. As long as the elastic cantilever arm and the spring key can be matched to meet the requirement that the contact component can be smoothly inserted into the connector housing, the process requirements for the contact fixing member are not high.

[0004] However, when traditional board-to-board connectors have more pins, it is difficult to ensure that all pinholes are in close contact due to factors such as processing technology. If the alignment is not accurate, it will cause problems such as pin breakage. Summary of the invention

[0005] The purpose of the present invention is to provide a highly reliable and stable connector in order to solve the above problems and overcome the defects of the prior art, as described in detail below.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides a highly reliable and stable connector, comprising a connection seat, a plurality of sockets are provided on the end surface of the connection seat, and the sockets are arranged in a rectangular array, a connector is provided at the end surface of the connection seat, a pin is fixedly connected to the end surface of the connector corresponding to the socket, and the pin is plugged into the socket at the corresponding position;

[0008] The area where the pin and the socket are plugged is provided with a reinforcement mechanism for enhancing the stability of the connection between the pin and the socket;

[0009] Limiting mechanisms are provided on both sides of the connecting seat and the connecting head for limiting the connecting seat and the connecting head;

[0010] A protective mechanism is provided between the connection seat and the connection head, for sealing the connection between the connection seat and the connection head;

[0011] The reinforcement mechanism includes a tapered hole, the tapered hole is opened on the inner wall of the plug pin, the outer wall of the plug pin is provided with an arc-shaped protrusion, and the position of the inner wall of the socket corresponding to the arc-shaped protrusion is provided with an arc-shaped depression for matching the arc-shaped protrusion. By setting the diameter of the entrance of the socket to be larger than the diameter of the pin head, the problem of misalignment during the connection process can be reduced. After the plug pin of the connector is inserted into the socket of the connector, the inner diameter of the socket will gradually shrink inward, and the plug pin will be slowly squeezed by the inner wall of the socket. The elastic force of the plug pin itself will make the contact position between the plug pin and the socket tighter, avoiding the problem of unstable electrical signal transmission caused by poor contact of the connector. In addition, the arc-shaped protrusion provided on the outer wall of the plug pin is stuck in the arc-shaped depression on the inner wall of the socket, which can improve the stability of the connection between the plug pin and the socket.

[0012] The connection seat is provided with a positioning mechanism, which is used to align the pins when plugged in, and to seal the connection seat to prevent dust when not plugged in.

[0013] Preferably, a collar is fixedly provided on the outer wall of the connector, and pressure blocks are fixedly connected to the positions on both sides of the bottom of the collar respectively.

By setting the push rod, when the connecting head and the connecting seat need to be separated, the push rods on both sides of the connecting seat can be squeezed by fingers, thereby driving the push block to squeeze the limit block, so that the limit block disengages from the limit groove to release the limit, thereby facilitating the separation of the connecting head and the connecting seat.

[0017] Preferably, the protective mechanism includes an air cushion, which is fixedly connected to the position of the ring on the inner wall of the connecting seat, and is used to increase the sealing of the connection between the connecting seat and the connecting head. By arranging the air cushion in the ring between the connecting seat and the connecting head, the connection between the connecting seat and the connecting head can be sealed, which can isolate impurities such as dust and liquid, and prevent impurities from entering the connection between the pin and the socket, resulting in poor contact or short circuit.

[0018] Preferably, air chambers are fixedly connected to both sides of the inner wall of the connecting seat, and the interior of the air chamber is connected to the interior of the air cushion through an air channel.

[0019] Preferably, the inner wall of the air chamber is slidably connected with an inflatable block, and the top of the inflatable block contacts the pressing block. When the ring drives the pressing blocks on both sides of the bottom to slide into the interior of the connecting seat and contact the inflatable block, the pressing block will squeeze the inflatable block and press the inflatable block into the interior of the air chamber, so that the interior of the air chamber is squeezed and air is injected into the air cushion from the airway, causing the air cushion to expand and fill the gap between the connecting seat and the connecting head, so that an enclosed space is formed between the connecting seat and the connecting head.

[0020] Preferably, a fourth spring is fixedly connected between the inner wall of the air chamber and the inflatable block for resetting the inflatable block.

[0021] Preferably, the positioning mechanism includes a protective frame, which is fixedly connected to the top of the connecting seat, a square groove is opened on the inner wall of the connecting seat, a guide rail groove is opened on the inner wall of the protective frame, one end of a long spring is fixedly connected to the bottom of the inner wall of the guide rail groove, the other end of the long spring is fixedly connected to a connecting slider, the outer wall of the connecting slider is slidably connected to the inner wall of the guide rail groove, the outer wall of the connecting slider is fixedly connected to a top positioning hole plate, the bottom of the top positioning hole plate is slidably connected to a bottom positioning hole plate, the inner walls of the top positioning hole plate and the bottom positioning hole plate are both provided with through holes, the through holes opened on the inner walls of the top positioning hole plate and the bottom positioning hole plate correspond to the jacks, the top positioning hole plate and the bottom positioning hole plate are elastically connected by a return spring, and the bottom of the bottom positioning hole plate is fixedly connected to a triangular prism block.

[0022] The beneficial effects are:

[0023] 1. The present invention can reduce the problem of misalignment during the connection process by setting the diameter of the entrance of the jack to be larger than the diameter of the pin head. After the pin of the connector is inserted into the jack of the connector, the inner diameter of the jack will gradually shrink inward, and the pin will be slowly squeezed by the inner wall of the jack. The elastic force of the pin itself will make the contact position between the pin and the jack tighter, avoiding the problem of unstable electrical signal transmission caused by poor contact of the connector. In addition, the stability of the connection between the pin and the jack can be improved by the arc-shaped protrusion on the outer wall of the pin being stuck in the arc-shaped depression on the inner wall of the jack.

[0024] 2. The present invention limits the connector by arranging limit blocks on both sides of the connector to be clamped inside the limit groove, so as to avoid displacement between the connector and the connector seat, which affects the stability of the connection between the connector and the connector seat, thereby improving the overall reliability of the connector. In actual use, when the pin on the connector is aligned with the socket of the connector seat and inserted, it will drive the pressure blocks on both sides of the bottom of the ring to slide into the interior of the connector seat. When the limit block slides into the interior of the connector seat, the inclined surface of the limit block contacts the frame of the connector seat, which will squeeze the limit block into the slide groove to avoid affecting the insertion of the connector seat. When the limit block moves to the position of the slide groove, the tension of the first spring will push the limit block to slide into the limit groove for clamping.

[0025] 3. The present invention can seal the connection between the connection seat and the connection head by arranging an air cushion in the ring between the connection seat and the connection head, which can isolate impurities such as dust and liquid, and prevent impurities from entering the connection between the pin and the socket, resulting in poor contact or short circuit. When the ring drives the pressure blocks on both sides of the bottom to slide into the interior of the connection seat and contact the inflatable block, the pressure blocks will squeeze the inflatable block and press the inflatable block into the interior of the air chamber, so that the interior of the air chamber is squeezed and air is injected into the air cushion from the airway, causing the air cushion to expand and fill the gap between the connection seat and the connection head, so that an enclosed space is formed between the connection seat and the connection head.

[0026] Fourth, when the connector is plugged into the connector socket, the present invention aligns the pin on the connector with the through hole on the top positioning hole plate. At this time, the pin moves downward through the through hole on the top positioning hole plate against the bottom positioning hole plate. The bottom positioning hole plate drives the top positioning hole plate and the triangular prism block to move downward at the same time, until the triangular prism block downwardly hits the square groove, and the square groove hits the inclined surface of the triangular prism block, so that the triangular prism block drives the bottom positioning hole plate to squeeze the return spring until the through hole of the bottom positioning hole plate moves to overlap with the top positioning hole plate. At this time, the pin can be inserted into the socket along the through hole of the bottom positioning hole plate. Before insertion, the socket in the protective frame is sealed and dustproof to prevent dust, liquid or other impurities from entering the socket. This can effectively avoid contamination inside the connector socket, especially the contact surface between the pin and the socket, ensure stable signal transmission during the plugging process, and avoid poor contact or short circuit problems caused by contamination.

[0027] 5. The present invention can accurately guide the pin to align with the socket through the through hole opened on the top positioning hole plate. During the connection process, the pin first passes through the through hole of the top positioning hole plate to ensure that the pin and the socket are accurately connected to avoid misalignment or poor contact during plugging.

[0049] How it works

[0050] When in use, the connector 2 is limited by setting limit blocks 9 on both sides of the connector 2 to be clamped in the limit groove 7 to prevent the connector 2 from being displaced with the connector 2 and the connector base 1, which affects the stability of the connection between the connector 2 and the connector base 1 and improves the overall reliability of the connector. In actual use, when the pin 3 on the connector 2 is aligned with the socket 4 of the connector base 1 and inserted, the pressure blocks 6 on both sides of the bottom of the ring 5 will be driven to slide into the connector base 1. When the limit block 9 slides into the connector base 1, the inclined surface of the limit block 9 contacts the frame of the connector base 1, which will squeeze the limit block 9 The first spring 10 is used to push the stopper 9 into the limit groove 7 to prevent the stopper 9 from being affected in inserting the connector 1. When the stopper 9 moves to the position of the limit groove 8, the tension of the first spring 10 pushes the stopper 9 to slide into the limit groove 7 for clamping. By setting the diameter of the entrance of the jack 4 to be larger than the diameter of the head of the pin 3, the problem of misalignment during the connection process can be reduced. After the pin 3 of the connector 2 is inserted into the jack 4 of the connector 1, the inner diameter of the jack 4 will gradually decrease inwards, and the pin 3 will be slowly squeezed by the inner wall of the jack 4. The elastic force of the pin 3 itself will make the position where the pin 3 contacts the jack 4 The arrangement is more tightly connected, thus avoiding the problem of unstable electrical signal transmission caused by poor contact of the connector, and the arc-shaped protrusion 32 on the outer wall of the pin 3 is stuck in the arc-shaped depression 41 on the inner wall of the jack 4, which can improve the stability of the connection between the pin 3 and the jack 4. When the ring 5 drives the pressing blocks 6 on both sides of the bottom to slide into the interior of the connecting seat 1 and contact the inflatable block 16, the pressing block 6 will squeeze the inflatable block 16 and press the inflatable block 16 into the air chamber 15, so that the air in the air chamber 15 is squeezed and the air is injected into the air cushion 14 from the air channel 17, so that the air cushion 14 expands and fills the air. The gap between the connecting base 1 and the connecting head 2 is filled, so that a closed space is formed between the connecting base 1 and the connecting head 2, which can isolate impurities such as dust and liquid, and prevent impurities from entering the connection between the pin 3 and the socket 4, resulting in poor contact or short circuit. In addition, by setting the push rod 12, when the connecting head 2 and the connecting base 1 need to be separated, the push rod 12 on both sides of the connecting base 1 can be squeezed by fingers, thereby driving the push block 11 to squeeze the limit block 9, so that the limit block 9 is disengaged from the limit groove 7 to release the limit, so as to facilitate the separation of the connecting head 2 and the connecting base 1.

[0051] When the connector 2 is plugged into the connector socket 1, the pin 3 on the connector 2 is aligned with the through hole on the top positioning hole plate 24. At this time, the pin 3 passes through the through hole on the top positioning hole plate 24 to abut against the bottom positioning hole plate 25 and moves downward. The bottom positioning hole plate 25 simultaneously drives the top positioning hole plate 24 and the triangular prism block 27 to move downward until the triangular prism block 27 abuts against the square groove 20 downward, and the square groove 20 abuts against the inclined surface of the triangular prism block 27, so that the triangular prism block 27 drives the bottom positioning hole plate 25 to squeeze the return spring 26 until the through hole of the bottom positioning hole plate 25 moves to overlap with the top positioning hole plate 24. At this time, the pin 3 can be inserted into the socket 4 along the through hole of the bottom positioning hole plate 25. Before insertion, the socket 4 in the protective frame 19 is sealed and dustproof to prevent dust, liquid or other impurities from entering the socket 4. This can effectively avoid contamination inside the connector 1, especially the contact surface between the pin 3 and the socket 4, ensuring stable signal transmission during the plugging process and avoiding poor contact or short circuit problems caused by contamination.

[0052] At the same time, the through hole opened on the top positioning hole plate 24 can accurately guide the pin 3 to align with the socket 4. During the connection process, the pin 3 first passes through the through hole of the top positioning hole plate 24 to ensure that the pin 3 and the socket 4 are accurately connected to avoid misalignment or poor contact during plugging.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
