Description

Technical Field

[0001] The present invention belongs to the technical field of BTB connectors, and more specifically, particularly relates to a BTB connector with an external protection structure. Background Art

[0002] As a key electronic connection component, BTB connectors are widely used in many electronic devices, such as smart phones, tablet computers, laptops, automotive electronic systems, and industrial control equipment. In these application scenarios, BTB connectors undertake the important task of achieving stable and efficient signal and power transmission between two circuit boards.

[0003] In practical applications, BTB connectors usually involve the following aspects: 1. Pin connection: The multiple metal pins of the male connector cooperate with the corresponding slots or contact pieces of the female connector to form a reliable electrical connection channel to ensure that various signals (such as data signals, control signals, etc.) and power can be accurately transmitted between the two circuit boards.

[0004] 2. Circuit board adaptation: It needs to be adapted and installed with circuit boards of different types, sizes and layouts to meet the complex circuit structure design requirements inside various electronic devices.

[0005] At present, in order to ensure the normal operation of BTB connectors in electronic equipment, manufacturers have adopted a variety of methods and designs. Some manufacturers focus on the improvement of pin materials and processes, using metal materials with high conductivity and good elasticity (such as phosphor bronze) to make pins, and ensure the accuracy and quality of the pins through precision stamping and molding processes to improve the stability and reliability of the connection. Other manufacturers optimize the insulation performance of the connector and use high-quality insulating materials to reduce signal interference and leakage risks. Some manufacturers are committed to improving the environmental resistance of the connector so that it can work normally under harsh conditions such as high temperature, high humidity, and strong vibration.

[0006] However, the above-mentioned prior art still has the following problems: in terms of physical protection, most BTB connectors lack an effective overall protection structure, and the pins are easily deformed, broken or worn by mechanical external forces (such as extrusion, collision, vibration, etc.) during transportation, installation and use, resulting in connection failure. At the same time, in a dusty or humid environment, dust can easily invade the inside of the connector and accumulate between the pins or on the contact points, increasing the contact resistance and affecting the signal transmission quality. Moisture can also corrode the metal pins, destroy the insulation performance, and cause electrical failures. In addition, electromagnetic interference (EMI) and radio frequency interference (RFI) can easily affect the transmission accuracy and stability of the internal signal of the connector, and the external radiation of the internal signal of the connector may also interfere with the normal operation of other devices. In terms of connection accuracy and convenience, some connectors lack an effective guiding structure, which is prone to mis-insertion during connection, resulting in pin damage, and some protective structures are difficult to install and remove, which is not conducive to the repair, upgrade and daily maintenance of the equipment. In view of these problems, this application proposes a solution to design a BTB connector with a protective shell, which is easy to disassemble, has a coating on the surface to achieve electromagnetic shielding, and is provided with a guiding and sealing structure, thereby comprehensively improving the BTB Connectors for performance, reliability and ease of use.

[0007] In view of this, the existing structure and defects are studied and improved, and a BTB connector with an external protection structure is provided to achieve a more practical purpose. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a BTB connector with an external protection structure to solve the above problems.

[0009] A BTB connector with an external protection structure comprises a female head and a male head, wherein the male head is movably connected with a protective shell on both the front and rear sides, and the two protective shells are fixedly connected with connecting blocks on both the left and right sides, the female head is movably connected with the male head, and the lower surface of the male head is fixedly connected with two guide bars, the front surfaces of the two connecting blocks located at the rear of the two pairs of connecting blocks are fixedly connected with two blocking blocks, and the rear surface of the protective shell located at the front of the two protective shells is fixedly connected with a group of fixed blocks, the rear surfaces of the two connecting blocks located at the front of the two pairs of connecting blocks are provided with a second card slot and two first card slots, and the two second card slots are movably connected with card blocks, the upper and lower sides of the two card blocks are fixedly connected with limited blocks, and the opposite surfaces of the two pairs of the blocking blocks are provided with limited slots, and the two second card slots are provided with a fifth card slot between the two second card slots and the two pairs of first card slots, and the two pairs of the fifth card slots are respectively movably connected with the two pairs of limiting blocks, and the two second card slots are rotatably connected with screws, and the two screws are respectively threadedly sleeved with the two card blocks, and the male head surface is fixedly connected with a connecting shell.

[0010] Preferably, a sealing groove is provided on the upper surface of the two protective shells, and a sealing ring is movably engaged in the two sealing grooves. Two guide grooves are provided on the upper surface of the female head, and the two guide grooves are movably engaged with two guide bars respectively. A group of annular grooves is provided on the upper surface of the two protective shells, and the two groups of annular grooves are movably engaged with the male head pins.

[0011] Preferably, the upper surfaces of the two protective shells are provided with strip grooves, and the two strip grooves are movably connected to the male head. The front surfaces of the protective shells located at the rear of the two protective shells are provided with a group of slots three, and the group of slots three are movably connected to a group of fixed blocks respectively.

[0012] Preferably, the two pairs of the slots 1 are movably connected to the two pairs of blocking blocks respectively, the two pairs of the limit slots are movably connected to the two pairs of limit blocks respectively, the front surfaces of the two connecting blocks located in the front of the two pairs of connecting blocks are provided with slots 4, and the two slots 4 are rotatably connected with toothed discs, and the two toothed discs are fixedly connected to the two screws respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the card block will drive the two limit blocks fixed with it to move during the movement. At this time, the two pairs of limit blocks will be respectively engaged with the limit grooves opened on the surfaces of the two pairs of blocking blocks, and the two will be limited. The two protective shells are also relatively fixed. The two protective shells can effectively protect the pins of the female head and reduce the pressure from the outside to cause extrusion deformation, breakage or wear. The easy-to-disassemble design of the two protective shells facilitates subsequent maintenance and repair. If a component of the connector is damaged, such as the pin is worn or the internal elastic component with poor contact fails, the easily disassembled protective shell makes replacement more efficient and reduces maintenance time.

[0014] In the present invention, the guide bar plays a guiding role, ensuring that the female connector and the male connector can be aligned in the correct direction, so that the pin of the male connector is accurately aligned with the slot of the female connector, which can effectively prevent the connector from being inserted incorrectly during assembly and damaging the pin or internal circuit. Since the guide bar can quickly guide the male connector and the female connector to be correctly connected, the operator can be more efficient in performing the connection operation. On the assembly line of large-scale production of electronic equipment, this design that can connect quickly and accurately can greatly improve production efficiency and reduce rework caused by connection errors.

[0015] In the present invention, when the female head and the male head are fully connected, the sealing ring is fully squeezed and tightly filled in the sealing groove between the female head and the male head, forming a good sealing state, which is very important for preventing dust, moisture and other impurities from entering the interior of the connector. In outdoor electronic equipment and humid or dusty equipment in industrial environments, this sealing structure can ensure the cleanliness and dryness of the inside of the connector, protect the internal electrical connection from interference from external environmental factors, thereby extending the service life of the connector and ensuring the stability of signal transmission.

[0016] In the present invention, the protective shell can prevent external mechanical impact and collision from causing damage to the connector pins and internal structure. The surface of the protective shell is coated with a conductive coating. When the electromagnetic wave reaches the coating surface, it will cause the generation of surface current, thereby realizing electromagnetic shielding. When the female head and the male head are connected, the protective shell covers the outside to form a relatively closed space. For some electronic devices with high requirements for electromagnetic compatibility, such as communication equipment, medical equipment, etc., this protection method helps to improve the overall performance of the equipment.

DETAILED DESCRIPTION

[0019] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0020] See also Figure 1 - Figure 8 The present invention provides a BTB connector with an external protection structure, including a female connector 1 and a male connector 2, wherein the male connector 2 is movably connected to a protective shell 4 on both the front and rear sides, and the two protective shells 4 are fixedly connected to connecting blocks 5 on both the left and right sides, the female connector 1 is movably connected to the male connector 2, and two guide strips 7 are fixedly connected to the lower surface of the male connector 2, and the front surfaces of the two connecting blocks 5 located at the rear of the two pairs of connecting blocks 5 are fixedly connected to two blocking blocks 11, and the rear surface of the protective shell 4 located at the front of the two protective shells 4 is fixedly connected to a group of fixed The fixed block 14, the rear surfaces of the two connecting blocks 5 located in the front of the two pairs of connecting blocks 5 are provided with a second card slot 10 and two card slots 1 9, the two card slots 10 are both movably connected with a card block 19, and the upper and lower sides of the two card blocks 19 are fixedly connected to the limited block 22, and the opposite surfaces of the two pairs of blocking blocks 11 are provided with a limited slot 12, and a card slot 5 23 is provided between the two card slots 20 and the two pairs of card slots 1 9, and the two pairs of card slots 5 23 are respectively movably connected with the two pairs of limit blocks 22, and the two card slots 10 are both rotatably connected. A screw 21 is connected, and the two screws 21 are respectively threadedly sleeved with the two blocks 19, and a connecting shell 3 is fixedly connected to the surface of the male head 2. When the two protective shells 4 are fully clamped, the screw 21 fixed thereto is driven to rotate together by toggling the toothed disk 20. During the rotation of the screw 21, the block 19 sleeved thereon is moved accordingly by the action of the thread. During the movement, the block 19 will drive the two limit blocks 22 fixed thereto to move together. At this time, the two pairs of limit blocks 22 will be respectively clamped with the limit grooves 12 opened on the surfaces of the two pairs of blocking blocks 11, and the two are limited. The two protective shells 4 are also relatively fixed. The two protective shells 4 can effectively protect the pins of the female head 1 to reduce the extrusion deformation, breakage or wear caused by external pressure. The design of the two protective shells 4 that is easy to disassemble facilitates later maintenance and overhaul. If a component of the connector is damaged, such as pin wear or failure of an internal elastic component with poor contact, the easily disassembled protective shell 4 makes replacement more efficient and reduces maintenance time.

[0021] The upper surfaces of the two protective shells 4 are each provided with a sealing groove 17, and a sealing ring 6 is movably engaged in the two sealing grooves 17. The upper surface of the female head 1 is provided with two guide grooves 8, and the two guide grooves 8 are movably engaged with the two guide strips 7 respectively. The upper surfaces of the two protective shells 4 are each provided with a group of annular grooves 16, and the two groups of annular grooves 16 are movably engaged with the pins of the male head 2. When the female head 1 and the male head 2 begin to be connected, the two guide strips 7 fixed on the surface of the male head 2 are first engaged with the two guide grooves 8 corresponding to the female head 1. The guide strips 7 play a guiding role to ensure that the female head 1 and the male head 2 can be aligned in the correct direction so that the pins of the male head 2 are accurately aligned with the slots of the female head 1. This can effectively prevent the connector from being inserted in the wrong direction during the assembly process and damaging the pins or internal circuits. Since the guide strips 7 can quickly guide the male head 2 and the female head 1 to be correctly connected, the operator can be more rapid when performing the connection operation. On the assembly line of large-scale production of electronic equipment, this design that can quickly and accurately connect can greatly improve production efficiency and reduce rework caused by connection errors.

[0022] A strip groove 15 is provided on the upper surface of the two protective shells 4, and the two strip grooves 15 are movably engaged with the male head 2. A group of slots 3 13 is provided on the front surface of the protective shell 4 at the rear of the two protective shells 4, and the group of slots 3 13 are movably engaged with a group of fixed blocks 14 respectively. As the female head 1 and the male head 2 gradually approach each other, the sealing ring 6 between the two begins to be squeezed. This squeezing process is gradual because the guide strip 7 ensures the correct docking path between the two to prevent deviation. When the female head 1 and the male head 2 are fully connected, the sealing ring 6 is fully squeezed and tightly filled in the sealing groove 17 between the female head 1 and the male head 2 to form a good sealing state, which is very important for preventing impurities such as dust and moisture from entering the interior of the connector. In outdoor electronic equipment and humid or dusty equipment in industrial environments, this sealing structure can ensure the cleanliness and dryness of the inside of the connector, protect the internal electrical connection from interference from external environmental factors, thereby extending the service life of the connector and ensuring the stability of signal transmission.

[0023] The two pairs of slots 19 are movably connected with the two pairs of blocking blocks 11 respectively, and the two pairs of limiting slots 12 are movably connected with the two pairs of limiting blocks 22 respectively. The front surfaces of the two connecting blocks 5 located in the front of the two pairs of connecting blocks 5 are provided with slots 4 18, and the two slots 4 18 are rotatably connected with toothed discs 20. The two toothed discs 20 are fixedly connected with two screws 21 respectively. The pins of the male head 2 just correspond to a group of annular grooves 16 on the protective shell 4, so as to ensure that the pins of the male head 2 can smoothly pass through the strip grooves 15 opened on the protective shell 4 and realize the electrical connection between the female head 1 and the male head 2, and the protective shell 4 can also normally cover the outside of the connected female head 1 and the male head 2. It plays a protective role. The groove design on the protective shell 4 can physically protect the connector without affecting the electrical connection, and the protective shell 4 can prevent external mechanical impact and collision from causing damage to the connector pins and internal structure. The surface of the protective shell 4 is coated with a conductive coating. When the electromagnetic wave reaches the coating surface, it will cause surface current to be generated, thereby achieving electromagnetic shielding. When the female head 1 and the male head 2 are connected, the protective shell 4 covers the outside to form a relatively closed space. For some electronic equipment with high requirements for electromagnetic compatibility, such as communication equipment, medical equipment, etc., this protection method helps to improve the overall performance of the equipment.

[0024] Working principle: In the first step, two protective shells 4 are movably connected to the surface of the female head 1 for protection. The two protective shells 4 will drive the connection blocks 5 fixed thereto to move during the connection process. The two blocking blocks 11 fixed on the surface of the connection blocks 5 located at the rear of the two pairs of connection blocks 5 will be connected with the connection blocks 5 in the front. The two protective shells 4 are guided by a group of fixed blocks 14 fixed thereon during the connection process to prevent the two protective shells 4 from being misaligned during the connection, ensuring the consistency of the connection and position of the two pairs of blocking blocks 11 and the two pairs of slots 10 opened on the surfaces of the two front connection blocks 5. When the two protective shells 4 are fully connected, the toothed disc 20 is driven to rotate with the screw 21 fixed thereto, and the screw 21 is sleeved thereon during the rotation process. The block 19 is moved accordingly by the action of the thread, and the block 19 will drive the two limit blocks 22 fixed thereto to move during the movement. At this time, the two pairs of limit blocks 22 will be respectively engaged with the limit grooves 12 opened on the surfaces of the two pairs of blocking blocks 11, and the two are limited. The two protective shells 4 are also relatively fixed. The two protective shells 4 can effectively protect the pins of the female head 1 to reduce the pressure from the outside and cause extrusion deformation, breakage or wear. The easy-to-disassemble design of the two protective shells 4 facilitates later maintenance and repair. If a component of the connector is damaged, such as the pin is worn or the internal elastic component with poor contact fails, the easily disassembled protective shell 4 makes replacement more efficient and reduces maintenance time.

[0025] In the second step, when the female connector 1 and the male connector 2 begin to be connected, the two guide strips 7 fixed on the surface of the male connector 2 are first engaged with the two guide grooves 8 corresponding to the female connector 1. The guide strips 7 play a guiding role to ensure that the female connector 1 and the male connector 2 can be aligned in the correct direction so that the pins of the male connector 2 are accurately aligned with the slots of the female connector 1. This can effectively prevent the connector from being inserted in the wrong direction during assembly and damaging the pins or internal circuits. Since the guide strips 7 can quickly guide the male connector 2 and the female connector 1 to be correctly connected, the operator can be more efficient in performing the connection operation. In the assembly line of large-scale production of electronic equipment, this design that can connect quickly and accurately can greatly improve production efficiency and reduce rework caused by connection errors. As the female connector 1 and the male connector 2 gradually approach each other, the sealing ring 6 between them begins to be squeezed. This squeezing process is gradual because the guide strip 7 ensures the correct docking path between the two to prevent deviation. When the female connector 1 and the male connector 2 are fully connected, the sealing ring 6 is fully squeezed and tightly filled in the sealing groove 17 between the female connector 1 and the male connector 2 to form a good sealing state, which is very important for preventing dust, moisture and other impurities from entering the interior of the connector. In outdoor electronic equipment and humid or dusty equipment in industrial environments, this sealing structure can ensure the cleanliness and dryness of the interior of the connector and protect the internal electrical connection from interference from external environmental factors, thereby extending the service life of the connector and ensuring the stability of signal transmission.

[0026] In the third step, the pins of the male connector 2 correspond exactly to a group of annular grooves 16 on the protective shell 4, so as to ensure that the pins of the male connector 2 can smoothly pass through the strip grooves 15 opened on the protective shell 4 and realize the electrical connection between the female connector 1 and the male connector 2, and the protective shell 4 can also normally cover the outside of the connected female connector 1 and the male connector 2 to play a protective role. The groove design on the protective shell 4 can physically protect the connector without affecting the electrical connection, and the protective shell 4 can prevent external mechanical shock and collision from causing damage to the connector pins and internal structure. The surface of the protective shell 4 is coated with a conductive coating. When the electromagnetic wave reaches the coating surface, it will cause the generation of surface current, thereby realizing electromagnetic shielding. When the female connector 1 and the male connector 2 are connected, the protective shell 4 covers the outside to form a relatively closed space. For some electronic equipment with high requirements for electromagnetic compatibility, such as communication equipment, medical equipment, etc., this protection method helps to improve the overall performance of the equipment.
