Description

Technical Field

[0001] The invention relates to the technical field of electrical connection, and in particular discloses a piercing connector which is convenient for optimizing line space. Background Art

[0002] With the rapid development of the connector industry, customers have increasingly higher requirements for various performances of connectors. In the past, the piercing connector of the aluminum substrate was specially provided with a cover that could cover the upper end of the connector clamping part in order to achieve the purpose of isolating the upper and lower ends of the electrical clamping part from the surface of the aluminum substrate. However, with the rapid advancement of science and technology, the position of the electrical contact part of the aluminum substrate is required to be changed from the back to the surface. In this way, the original connector is obviously no longer applicable. At the same time, in the original connection method, since the electrical connection part of the aluminum substrate is on the back, which is opposite to the wiring direction of the connector, the direction of the wire needs to go around a large circle when connected to the connector, which not only makes the circuit layout look chaotic, but also affects the overall aesthetics and stability to a certain extent. For example, in the manufacture of some precision electronic equipment, the disorder of the circuit may interfere with the transmission of the signal and even cause the equipment to malfunction. For example, in the equipment with limited space, the connection method of the circuit going around a large circle will occupy too much space, which is not conducive to the miniaturization and integration of the equipment. Therefore, a piercing connector that is convenient for optimizing the circuit space is urgently needed. Summary of the invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a piercing connector that is convenient for optimizing line space.

[0005] Preferably, the terminal is a wire end piercing terminal, the terminal includes a frame body, a piercing portion and an elastic clamping arm located on the frame body, the piercing portion and the elastic clamping arm are respectively provided with two and symmetrically arranged, the piercing portion and the elastic clamping arm are respectively located at the two ends of the frame body, the piercing portion is located at the position of the wire slot, the wire slot is the first slot body, the design of the piercing portion enables it to directly pierce the insulating layer of the wire material and the conductive layer to form an electrical connection when connecting to an external circuit board, without the need for additional welding or crimping steps, thereby greatly improving the efficiency and convenience of the connection, the symmetrical arrangement of the piercing portion and the elastic clamping arm, and their respective locations at the two ends of the frame body, ensure the balance and stability of the connection. The elastic clamping arm can provide a certain clamping force, maintain close contact between the circuit board and the terminal, and avoid poor contact or disconnection caused by vibration or external force. Since the design of the piercing portion and the elastic clamping arm is compact and symmetrical, the installation of the entire terminal on the rubber seat is more reasonable, which helps to optimize the line space layout inside the device and make the overall structure more compact and beautiful.

[0006] Preferably, a sixth groove is provided on the piercing portion, and two puncture needle portions are formed on the piercing portion through the sixth groove, and the two puncture needle portions are used to pierce the wire. The design of the sixth groove enables the piercing portion to form two sharp puncture needle portions, and the two puncture needle portions can apply force more concentratedly when piercing the wire, thereby more easily penetrating the insulating layer and the conductive layer of the wire to achieve a stable electrical connection. This design improves the connector's ability to pierce the wire, especially when facing a thicker or harder insulating layer, it can still maintain an efficient piercing effect. Due to the flexibility and sharpness of the puncture needle portion, the connector can adapt to wires of various specifications and materials. Regardless of whether the wire is thinner or thicker, the connector can achieve a stable connection through the puncture needle portion, thereby improving the applicability and compatibility of the connector.

[0007] Preferably, the protective cover is made of insulating material. After the protective cover is installed in the rubber seat, the two elastic clamping arms on the terminal are respectively in contact with the protective cover and the external circuit board to stop / clamp the external circuit board. The protective cover is made of insulating material, which ensures that the protective cover itself will not become part of the conductive path during the operation of the connector, thereby effectively preventing the occurrence of safety hazards such as electrical short circuit or leakage. This design improves the electrical safety and reliability of the connector. When the protective cover is installed in the rubber seat, the two elastic clamping arms on the terminal are respectively in contact with the protective cover and the external circuit board to form a stable clamping structure.

[0008] Preferably, the protective cover includes a second frame body, on which a cut corner is provided, and the cut corner is used to form a position-avoiding guide structure when an external circuit board is installed. The existence of the cut corner provides a position-avoiding guide structure for the installation of the external circuit board, which means that when the external circuit board is installed into the combination of the protective cover and the rubber seat, the cut corner can guide the circuit board to smoothly enter the predetermined position, reducing the installation difficulties caused by inaccurate positioning or excessive resistance, thereby simplifying the entire installation process.

[0010] Preferably, a plurality of third grooves are provided on the second frame body, and the plurality of third grooves are arranged in an array, and the third grooves are used to separate the end of the second frame body away from the third protrusion into a plurality of pieces. By separating one end of the second frame body into a plurality of pieces, these pieces can produce a certain elastic deformation when subjected to external circuit board pressure, thereby enhancing the clamping ability of the protective cover on the circuit board. At the same time, the opening of the third grooves increases the heat dissipation area of ​​the surface of the second frame body, which helps to dissipate the heat inside the connector. The third grooves can also reduce the weight of the protective cover to a certain extent, which helps to reduce the weight of the entire connector.

[0011] Preferably, the adhesive seat includes a first frame body, a second groove body for accommodating the second frame body and an external circuit board is provided on the first frame body, a first protrusion is provided on the first frame body, and a chamfer is provided on one end of the first protrusion for the external circuit board to enter, and the circuit board includes a first plate body, a fifth groove body for accommodating the first protrusion is provided on the first plate body, the first protrusion on the first frame body matches the fifth groove body on the circuit board, thereby realizing precise positioning between the circuit board and the adhesive seat, such design ensures the position accuracy of the circuit board during installation, and avoids performance problems or damage caused by position deviation, and a stable connection is formed between the circuit board and the adhesive seat through the close cooperation between the first protrusion and the fifth groove body, such connection mode not only improves the stability of the circuit board, but also helps to resist the influence of external vibration or impact on the circuit board, and protects the normal operation of the circuit board, and the chamfer is provided at the end of the first protrusion where the external circuit board enters, which helps the smoothness of the circuit board during the insertion process, and the chamfer can reduce the resistance during insertion, and prevent the circuit board from being scratched or damaged during the insertion process, thereby simplifying the installation process and improving the installation efficiency.

[0012] Preferably, a second protrusion is further provided on the first frame body, and a fourth groove body is provided on the first plate body for avoiding / accommodating the second protrusion. The cooperation between the second protrusion and the fourth groove body further enhances the positioning accuracy between the circuit board and the adhesive seat. During the installation of the circuit board, the second protrusion can be accurately inserted into the fourth groove body. The combination of the second protrusion and the fourth groove body also increases the connection strength between the circuit board and the adhesive seat. This multi-point connection method makes the circuit board less likely to loosen or fall off when subjected to external force, thereby improving the stability and reliability of the connection.

[0013] Preferably, the rubber seat and the protective cover are both formed by integral injection molding. As important components of the connector, the performance of the rubber seat and the protective cover directly affects the overall performance of the connector. The integral injection molding technology can ensure that the rubber seat and the protective cover achieve the best performance state during the injection molding process, such as good structural stability and consistency, thereby improving the overall performance of the connector.

[0014] The beneficial effects of the present invention are as follows: by positively inserting the circuit board into the rubber seat and electrically connecting it to the terminal, a consistent line direction can be achieved.

[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0028] See also Figures 1 to 10 As shown, a piercing connector for optimizing circuit space of the present invention includes a rubber seat 1 and a terminal 2, wherein the terminal 2 is mounted on the rubber seat 1, and an external circuit board is mounted on the rubber seat 1 to form an electrical connection with the terminal 2, and a first slot 15 for entering the line is provided on the rubber seat 1, and a protective cover 3 is also included, and the protective cover 3 forms a detachable assembly structure with the rubber seat 1 through a plug-in connection; the protective cover 3 cooperates with the terminal 2 to clamp the external circuit board 4, and the protective cover 3 is used to insert the external circuit board 4 into the rubber seat 1 in the forward direction and electrically connect with the terminal 2.

[0029] Specifically, by positively inserting the circuit board 4 into the rubber seat 1 and electrically connecting it to the terminal 2, a consistent line direction can be achieved. The consistent line direction can greatly optimize the internal space utilization, reduce the possibility of signal interference, ensure the performance and stability of the line, and make the overall layout more compact. The consistent line direction can reduce the probability of failure and improve maintenance efficiency. The protective cover 3 not only protects the external circuit board 4, but also enhances the clamping force between the external circuit board 4 and the terminal 2 through the use in conjunction with the terminal 2, thereby improving the stability and reliability of the electrical connection and reducing the signal interruption or quality degradation caused by factors such as poor contact or vibration. Since a detachable plug-in connection method is adopted between the protective cover 3 and the rubber seat 1, when the external circuit board 4 needs to be replaced or maintained, the protective cover 3 can be easily and quickly removed without disassembling the entire connector, thereby greatly improving the maintenance efficiency and upgrade convenience of the equipment.

[0030] Specifically, the protective cover 3 is arranged at the bottom of the external circuit board 4 to stop the external circuit board 4, so that the contact piece of the external circuit board 4 can be inserted in the forward direction, which is convenient for the staff to check. At the same time, the forward insertion of the external circuit board 4 can also make the wires on the circuit board 4 correspond to the wires inserted into the rubber seat 1 one by one, which is beneficial to the consistency of the line. Through the forward insertion of the circuit board 4, the consistent direction of the line can be achieved. This consistent direction can greatly optimize the internal space utilization, reduce the possibility of signal interference, and ensure the performance and stability of the line. At the same time, the compact layout also helps to reduce the probability of failure and improve the reliability of the overall equipment.

[0031] Specifically, the terminal 2 is a wire end piercing terminal, and the terminal 2 includes a frame portion 21, a piercing portion 22 located on the frame portion 21, and an elastic clamping arm 24. The piercing portion 22 and the elastic clamping arm 24 are respectively provided with two and symmetrically arranged. The piercing portion 22 and the elastic clamping arm 24 are respectively located at the two ends of the frame portion 21. The piercing portion is located at the position of the wire groove, and the wire groove is the first groove body 15. The design of the piercing portion 22 enables it to directly pierce the insulating layer of the wire and the conductive layer to form an electrical connection when connecting to an external circuit board, without the need for additional welding or crimping steps, thereby greatly improving the efficiency and convenience of the connection. The symmetrical arrangement of the piercing portion 22 and the elastic clamping arm 24, and their respective locations at the two ends of the frame portion 21, ensure the balance and stability of the connection. The elastic clamping arm 24 can provide a certain clamping force to maintain close contact between the circuit board and the terminal 2, avoiding poor contact or disconnection due to vibration or external force. Since the piercing portion 22 and the elastic clamping arm 24 are compactly and symmetrically designed, the installation of the entire terminal 2 on the rubber seat 1 is more reasonable, which helps to optimize the circuit space layout inside the equipment and make the overall structure more compact and beautiful.

[0032] Specifically, a sixth slot 23 is provided on the piercing portion 22, and two puncture needles are formed on the piercing portion 22 through the sixth slot 23. The two puncture needles are used to pierce the wire. The design of the sixth slot 23 enables the piercing portion 22 to form two sharp puncture needles. The two puncture needles can apply force more concentratedly when piercing the wire, thereby making it easier to penetrate the insulating layer and the conductive layer of the wire to achieve a stable electrical connection. This design improves the connector's ability to pierce the wire, especially when facing a thicker or harder insulating layer, it can still maintain an efficient piercing effect. Due to the flexibility and sharpness of the puncture needle, the connector can adapt to wires of various specifications and materials. Regardless of whether the wire is thinner or thicker, the connector can achieve a stable connection through the puncture needle, thereby improving the applicability and compatibility of the connector.

[0033] Specifically, the protective cover 3 is made of insulating material. After the protective cover 3 is installed in the rubber seat 1, the two elastic clamping arms 24 on the terminal 2 are respectively in contact with the protective cover 3 and the external circuit board 4 to stop / clamp the external circuit board 4. The protective cover 3 is made of insulating material, which ensures that the protective cover 3 itself will not become a part of the conductive path during the operation of the connector, thereby effectively preventing the occurrence of safety hazards such as electrical short circuit or leakage. This design improves the electrical safety and reliability of the connector. When the protective cover 3 is installed in the rubber seat 1, the two elastic clamping arms 24 on the terminal 2 are respectively in contact with the protective cover 3 and the external circuit board 4 to form a stable clamping structure. This clamping method not only enhances the connection stability between the external circuit board 4 and the connector, but also reduces the problem of poor contact or falling off caused by vibration or external force. The entire connection process is simple, fast, stable and reliable, which not only improves work efficiency, but also brings a better user experience.

[0034] Specifically, the protective cover 3 includes a second frame body 31, and a cut corner 34 is opened on the second frame body 31. The cut corner 34 is used to form a position-avoiding guide structure when the external circuit board 4 is installed. The existence of the cut corner 34 provides a position-avoiding guide structure for the installation of the external circuit board 4, which means that when the external circuit board 4 is installed into the combination of the protective cover 3 and the rubber seat 1, the cut corner 34 can guide the circuit board to smoothly enter the predetermined position, reducing the installation difficulties caused by inaccurate positioning or excessive resistance, thereby simplifying the entire installation process.

[0035] Specifically, a third protrusion 33 and a fourth protrusion 35 are further protruded from the second frame body 31. The third protrusion 33 is arranged on one side of the second frame body 31 for contacting the external circuit board 4. The third protrusion 33 is used to stop one end of the external circuit board 4. The second frame body 31 is used to snap on the first frame body 11 via the fourth protrusion 35. The third protrusion 33 is arranged on the side of the second frame body 31 that contacts the external circuit board 4. Its function is to stop the end of one end of the external circuit board 4, which can prevent the circuit board from shaking or shifting inside the connector, thereby improving the stability and reliability of the connection. The fourth protrusion 35 can snap on the first frame body 11, so that the protective cover 3 can be more firmly fixed on the rubber seat 1, thereby enhancing the structural strength of the entire connector. At the same time, this snapping method also simplifies the installation process, allowing users to more easily install the protective cover in place.

[0036] Specifically, a plurality of third grooves 32 are provided on the second frame 31, and the plurality of third grooves 32 are arranged in an array.

By dividing one end of the second frame into a plurality of pieces, these pieces can produce a certain elastic deformation when subjected to external circuit board pressure, thereby enhancing the clamping ability of the protective cover 3 on the circuit board. At the same time, the opening of the third grooves 32 increases the heat dissipation area on the surface of the second frame 31, which helps to dissipate the heat inside the connector. The third grooves 32 can also reduce the weight of the protective cover 3 to a certain extent, which helps to reduce the weight of the entire connector.

[0037] Specifically, the adhesive seat 1 includes a first frame 11, a second slot 12 for accommodating a second frame 31 and an external circuit board 4 is provided on the first frame 11, a first protrusion 13 is provided on the first frame 11, and a chamfer is provided on one end of the first protrusion 13 for the external circuit board 4 to enter, and the circuit board 4 includes a first plate 41, a fifth slot 43 for accommodating the first protrusion 13 is provided on the first plate 41, and the first protrusion 13 on the first frame 11 matches the fifth slot 43 on the circuit board 4, so that the circuit board 4 and the adhesive seat 1 are accurately positioned. This design ensures the position of the circuit board 4 during the installation process. Accuracy is achieved, and performance problems or damage caused by position deviation are avoided. Through the close fit between the first protrusion 13 and the fifth groove body 43, a stable connection is formed between the circuit board 4 and the rubber seat 1. This connection method not only improves the stability of the circuit board, but also helps to resist the influence of external vibration or impact on the circuit board and protect the normal operation of the circuit board. The chamfer is set at the end of the first protrusion 13 where the external circuit board 4 enters, which helps the smoothness of the circuit board during the insertion process. The chamfer can reduce the resistance during insertion and prevent the circuit board from being scratched or damaged during the insertion process, thereby simplifying the installation process and improving the installation efficiency.

[0038] Specifically, a second protrusion 14 is further provided on the first frame body 11, and a fourth groove body 42 is provided on the first plate body 41 for avoiding / accommodating the second protrusion 14. The cooperation between the second protrusion 14 and the fourth groove body 42 further enhances the positioning accuracy between the circuit board 4 and the adhesive seat 1. During the installation of the circuit board 4, the second protrusion 14 can be accurately inserted into the fourth groove body 42. The combination of the second protrusion 14 and the fourth groove body 42 also increases the connection strength between the circuit board and the adhesive seat. This multi-point connection method makes the circuit board less likely to loosen or fall off when subjected to external force, thereby improving the stability and reliability of the connection.

[0039] Specifically, the second protrusion 14 is disposed in a non-central area of ​​the first frame body 11 to achieve a foolproof effect.

[0040] Specifically, the rubber seat 1 and the protective cover 3 are both integrally injection molded. As important components of the connector, the performance of the rubber seat 1 and the protective cover 3 directly affects the overall performance of the connector. The integral injection molding technology can ensure that the rubber seat 1 and the protective cover 3 achieve the best performance state during the injection molding process, such as good structural stability and consistency, thereby improving the overall performance of the connector.

[0042] Specifically, the surface of the elastic member 37 is coated with a damping material / special coating layer 38. The damping material / special coating layer 38 coated on the surface of the elastic member 37 can effectively suppress the energy transfer of the structure during the vibration process, thereby reducing vibration and noise, etc. The damping material / special coating layer 38 includes rubber damping materials such as natural rubber, synthetic rubber: such as nitrile rubber, polyurethane rubber, etc.; plastic damping materials, polymer damping materials: such as polyacrylate, polyurethane, epoxy resin, etc.; foam plastics: such as polyurethane foam; composite materials; damping composite materials: composed of damping materials (such as rubber, plastic) as sandwich layers, combined with metal or non-metallic structural materials; fiber composite materials: reinforcing materials such as carbon fiber and glass fiber, combined with damping materials to form high-performance damping composite materials; high damping alloys: such as copper-zinc-aluminum, iron-chromium-molybdenum and manganese-copper alloys; polymer resin damping coatings: prepared by adding appropriate amounts of fillers and auxiliary materials to polymer resins; water-based damping coatings, etc.

[0045] Specifically, the user presses down the circuit board 4 to squeeze the elastic member 37 via the second plate body 36 to cancel the limit between the circuit board 4 and the plastic seat 1, making it easier to take out.

[0046] Specifically, the second plate 36 and / or the second frame 31 is coated with a shock-absorbing coating on one side for supporting the external circuit board 4. The shock-absorbing coating is an elastic polymer coating that can effectively absorb shock and vibration, thereby protecting the chip from mechanical damage. In addition, the elastic polymer coating can also provide a certain degree of damping effect, reduce the friction between the base and the chip, and facilitate the plugging and unplugging of the chip. Elastic polymer materials such as silicone and polyurethane are often used as buffers and protective layers for electronic components; nano-composite coatings combine the excellent properties of nanoparticles, such as high strength, high toughness, and wear resistance, and may also have self-repairing functions. The nano-composite coating can not only provide effective shock-absorbing protection, but also enhance the wear resistance and durability of the second frame 31; Metal-based composite coatings: by combining metal with composite materials such as ceramics and polymers to form a coating with excellent mechanical properties and thermal stability, the metal-based composite coating not only has high strength and hardness, but also can maintain stable performance in high temperature environments, providing reliable protection for the chip.
