Description

Technical Field

[0001] The present invention belongs to the technical field of BTB connectors, and more 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 numerous electronic devices, including smartphones, tablets, laptops, automotive electronic systems, and industrial control equipment. In these applications, BTB connectors play the crucial role of ensuring stable and efficient signal and power transmission between two circuit boards.

[0003] In practical applications, BTB connectors usually involve the following aspects:

[0004] 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.

[0005] 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.

[0006] To ensure the proper function of BTB connectors in electronic devices, manufacturers are employing a variety of methods and designs. Some focus on improving pin materials and processes, using highly conductive and elastic metals (such as phosphor bronze) to manufacture pins. Precision stamping and forming processes ensure pin accuracy and quality, enhancing connection stability and reliability. Others optimize the connector's insulation performance, selecting high-quality insulating materials to reduce the risk of signal interference and leakage. Others are working to improve the connector's environmental resistance, enabling it to operate properly in harsh conditions such as high temperature, high humidity, and high vibration.

[0007] However, the above-mentioned prior art still has the following problems: In terms of physical protection, most BTB connectors lack an effective overall protective structure, and the pins are easily deformed, broken, or worn due to mechanical external forces (such as extrusion, collision, vibration, etc.) during transportation, installation, and use, resulting in connection failure. At the same time, in dusty or humid environments, dust can easily penetrate the interior of the connector and accumulate between the pins or on the contact points, increasing contact resistance and affecting 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 signals within the connector. The radiation of internal signals from the connector may also interfere with the normal operation of other devices. In terms of connection accuracy and convenience, some connectors lack effective guide structures, which can easily lead to mis-insertion during connection, resulting in pin damage. In addition, some protective structures are difficult to install and remove, which is not conducive to equipment repair, upgrade, and routine maintenance. To address these problems, this application proposes a solution to design a BTB connector with a protective shell. The protective shell is easy to disassemble, has a surface coating for electromagnetic shielding, and is provided with a guide and sealing structure, thereby comprehensively improving the BTB. Connector performance, reliability and ease of use.

[0008] In view of this, research and improvement are conducted on the existing structure and defects, and a BTB connector with an external protection structure is provided to achieve a more practical purpose. Summary of the Invention

[0009] 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.

[0011] 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 the 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.

[0012] Preferably, a strip groove is provided on the upper surface of the two protective shells, and the two strip grooves are movably connected to the male head. A group of three card slots are provided on the front surface of the protective shells located at the rear of the two protective shells, and the group of three card slots are movably connected to a group of fixed blocks respectively.

[0013] Preferably, the two pairs of the card 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, and the front surfaces of the two connecting blocks located in the front of the two pairs of connecting blocks are each provided with a card slot 4, and the two card slots 4 are both rotatably connected to a gear disk, and the two gear disks are respectively fixedly connected to two screws.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, the card block will drive the two limit blocks fixed to it to move during the movement process. 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 inspection. If a component of the connector is damaged, such as pin wear or failure of the internal elastic component with poor contact, the easily disassembled protective shell makes replacement more efficient and reduces maintenance time.

[0016] 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 pins of the male connector are accurately aligned with the slots of the female connector. This can effectively prevent the connector from being inserted incorrectly during assembly and damaging the pins or internal circuits. Since the guide bar can quickly guide the male connector and the female connector to be correctly connected, the operator can be more efficient when 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.

[0017] In the present invention, when the female and male connectors are fully connected, the sealing ring is fully squeezed and tightly filled in the sealing groove between the female and male connectors, forming 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 interior 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.

[0018] 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 electromagnetic waves reach the coating surface, it will cause surface current to be generated, thereby achieving electromagnetic shielding. When the female and male plugs 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

[0028] The following embodiments of the present invention are described in further detail with reference to 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.

[0029] 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. The male connector 2 is movably connected to a protective shell 4 on both the front and rear sides. The two protective shells 4 are fixedly connected to a connecting block 5 on both the left and right sides. The female connector 1 is movably connected to the male connector 2. The lower surface of the male connector 2 is fixedly connected to two guide strips 7. 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. The rear surface of the protective shell 4 located at the front of the two protective shells 4 is fixedly connected to a set of fixed The fixed block 14, the two connecting blocks 5 located in the front of the two pairs of connecting blocks 5 are provided with a card slot 2 10 and two card slots 1 9 on the rear surface, the two card slots 2 10 are both movably connected with a card block 19, the two card blocks 19 are fixedly connected to the limit block 22 on both sides, the two pairs of blocking blocks 11 are provided with a limit slot 12 on the opposite sides, the two card slots 2 10 and the two pairs of card slots 9 are provided with a card slot 5 23, the two pairs of card slots 5 23 are respectively connected to the two pairs of limit blocks 22, and the two card slots 2 10 are both rotatably connected. The two protective shells 4 are also relatively fixed. The pins of the female head 1 can be effectively protected by the two protective shells 4, reducing the pressure on the pins to cause them to be squeezed, deformed, broken or worn. The easy-to-remove design of the two protective shells 4 facilitates later maintenance and repair. If a component of the connector is damaged, such as pin wear or failure of an internal elastic component with poor contact, the easily removable protective shell 4 makes replacement more efficient and reduces maintenance time.

[0030] 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 start to be connected, the two guide strips 7 fixed on the surface of the male head 2 first engage with the two guide grooves 8 corresponding to the female head 1. The guide strips 7 play a guiding role, ensuring 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 incorrectly during assembly 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 efficient when 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.

[0031] Both protective shells 4 have strip grooves 15 on their upper surfaces, and both strip grooves 15 are movably engaged with the male head 2. A group of slots three 13 are provided on the front surface of the protective shell 4 at the rear of the two protective shells 4, and a group of slots three 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 and prevents 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, 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.

[0032] The two pairs of card slots 19 are respectively movably connected with the two pairs of blocking blocks 11, and the two pairs of limit slots 12 are respectively movably connected with the two pairs of limit blocks 22. The front surfaces of the two connection blocks 5 located in the front of the two pairs of connection blocks 5 are provided with card slots 4 18. The two card slots 4 18 are rotatably connected with toothed discs 20. The two toothed discs 20 are respectively fixedly connected with two screws 21. The pins of the male connector 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 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. 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 realizing 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.

[0033] Working principle:

[0034] In the first step, the surface of the female head 1 is movably connected with two protective shells 4 for protection. The two protective shells 4 will drive the connecting block 5 fixed thereto to move during the connection process. The two blocking blocks 11 fixed on the surface of the connecting block 5 at the rear of the two pairs of connecting blocks 5 will be connected with the connecting block 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. This ensures that the two pairs of blocking blocks 11 are connected to the two pairs of card slots 10 opened on the surfaces of the two front connecting blocks 5 for card connection and position consistency. 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 card block 19 is moved accordingly by the action of the thread, and the card block 19 will drive the two limit blocks 22 fixed to it 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, reducing the external pressure that causes extrusion deformation, breakage or wear. The easy-to-disassemble design of the two protective shells 4 facilitates subsequent maintenance and inspection. 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.

[0035] 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 plugged in the wrong way 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 and prevents 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, forming a good sealing state. This 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 interior 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.

[0036] In the third step, the pins of the male connector 2 correspond exactly to a set 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 electromagnetic waves reach the coating surface, it will cause surface current to be generated, 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.

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as are suited for specific applications.
