Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to a terminal and an electrical connector. Background Technology

[0002] Electrical connectors are devices used in electrical and electronic equipment to connect and disconnect circuits. Connector terminals are a key component of electrical connectors, used to make electrical contact with other conductors to transmit current or electrical signals. Therefore, the performance of the terminals has a decisive impact on the performance and quality of the electrical connector. To improve the conductivity, corrosion resistance, and mechanical strength of the terminals, electroplating technology is typically used to protect the terminal substrate from environmental corrosion and optimize the surface properties of the terminals.

[0003] In the existing technology, due to the complex shape of the terminal and the fact that the surface is often composed of multiple curved surfaces, it is impossible to electroplate the surface evenly. As a result, the electroplated film layer is thin or the areas that cannot be electroplated are prone to oxidation, which affects the overall performance and service life of the electrical connector. Utility Model Content

[0004] This application provides a terminal and electrical connector that achieves the effects of simple manufacturing and easy electroplating.

[0005] The terminal provided in this application adopts the following technical solution: The main body has a sheet-like structure; A fixing part is connected to one end of the main body; and The contact portion extends from one end of the main body away from the fixing portion. The contact portion includes a first contact arm and a second contact arm. The first contact arm and the second contact arm are symmetrically arranged about the centerline of the width direction of the main body and form a Y-shaped layout with the main body. A first protrusion flush with the side is formed on the surface of the first contact arm perpendicular to the side, and a second protrusion flush with the side is formed on the surface of the second contact arm perpendicular to the side. An electroplated layer is formed on the surface of the first protrusion and the second protrusion.

[0006] By adopting the above technical solution, through the structural design of the main body, fixing part, and contact part, the first contact arm and the second contact arm form a Y-shaped layout. The Y-shaped layout causes the first and second contact arms to tend to grip inward, so that the terminal applies stable contact pressure to the mating terminal during insertion and removal, improving the reliability and stability of the connection. The first and second contact arms are symmetrically arranged about the centerline of the width direction of the main body, so that the force is evenly distributed, which helps to ensure the stability of the terminal. In the electroplating process, only the first and second protrusions need to be electroplated, so the area to be electroplated is small, reducing the electroplating cost. The first and second protrusions form a double-point contact, which provides a more stable contact method when the terminal is inserted with the mating terminal, avoiding the contact failure that may occur after long-term use of single-point contact, thereby enhancing the reliability of the terminal. The first and second protrusions have simple shapes, avoiding the formation of folding gaps that would reduce electroplating efficiency, while reducing the cost and difficulty of manufacturing stamping dies to improve production efficiency.

[0007] Optionally, a gap is formed between the first contact arm and the second contact arm, and the width of the gap is set to gradually narrow from the direction of approaching to the direction of moving away from the main body.

[0008] By adopting the above technical solution, the contact portion forms an elastic structure. When the mating terminal is inserted, the contact portion can generate contact pressure through elastic deformation, thereby enhancing the tightness of the connection. The width of the interval is set to gradually narrow from the direction close to the main body, which can concentrate the elastic deformation of the contact area, further increase the contact pressure, reduce the contact resistance, and improve the conductivity.

[0009] Optionally, the fixing part is arranged at a 90° angle to the main body, and the width of the fixing part is smaller than the width of the main body.

[0010] By adopting the above technical solution, the fixing part and the main body are set at a 90° angle so that the terminals are suitable for dense arrangement and save horizontal space; axial positioning is achieved by the width difference between the fixing part and the main body to avoid displacement.

[0011] Optionally, limiting portions are formed on opposite sides of the main body, and the limiting portions cause the width of the main body to vary in a convex-concave manner.

[0012] By adopting the above technical solution, the limiting part expands the volume of the main body, so that during installation or use, the side of the main body protrudes, so that the terminal is deformed and stressed in the width direction before the contact part and the fixing part, thereby protecting the contact part and the fixing part.

[0013] Optionally, positioning protrusions are formed on opposite sides of the fixing part.

[0014] By adopting the above technical solution, the positioning protrusion cooperates with the external mounting hole to form an interference fit or slot structure, preventing the terminal from falling off. At the same time, the positioning protrusion can serve as an installation marker, making it easy for operators to judge the stability of the terminal connection to other electrical components.

[0015] The electrical connector provided in this application adopts the following technical solution: Multiple terminals; The socket has multiple receiving cavities extending through opposite sides of the socket, the multiple receiving cavities being arranged in a multi-layered array, with adjacent layers forming a stepped shape; and A cover is slidably fitted with a socket, and the cover has an array of through holes; one end of the contact portion of the terminal is inserted into the receiving cavity and located in the receiving cavity, and the fixing portion of the terminal extends out from the through holes.

[0016] By adopting the above technical solution, the multiple receiving cavities are arranged in a multi-layer array, with adjacent layers forming a stepped shape, and the cover has an array of through holes, so that the contact parts of the multiple terminals cooperate with the receiving cavities, the fixing parts cooperate with the through holes, and the cover slides with the socket to realize that the multiple terminals are housed inside the electrical connector, avoiding the terminals from being affected by the external environment during the contact and mating process; the through holes are used for the fixing parts to extend, so that the terminal is exposed to connect to the external circuit, ensuring the reliability of the electrical connection.

[0017] Optionally, the cover also includes a limiting baffle, each limiting baffle corresponding to a row of through holes, and the corresponding terminal can abut against the limiting baffle after being inserted into the through hole.

[0018] By adopting the above technical solution, the limiting baffle positions the multiple rows of terminals in groups, and one limiting baffle corresponds to one row of through holes. After the terminal is inserted, it abuts against the limiting baffle to ensure that the end of the contact part is on the same tangent plane perpendicular to the surface of the receiving cavity, thus avoiding poor contact caused by the terminal being inserted too deeply or too shallowly.

[0019] Optionally, the through hole is a tapered hole, which can stop the insertion position of the positioning protrusion included in the fixing part.

[0020] By adopting the above technical solution, the through hole restricts the length of the fixing part that can pass through the cover, thereby limiting the axial movement of the terminal and achieving reliable fixing; the through hole is a tapered hole to accommodate the positioning protrusion within a certain size range, thereby reducing the processing accuracy requirements of the electrical connector; at the same time, when the cover is subjected to force, the stress can be dispersed by the tapered surface of the through hole, avoiding damage caused by local stress concentration.

[0021] Optionally, the cover has a first stop on the surface opposite to the fixing part, and the bottom of the socket has a second stop, the first stop cooperating with the second stop to limit the sliding position of the socket.

[0022] By adopting the above technical solution, the first stop and the second stop cooperate to restrict the position of the socket and accurately fit the cover, while preventing the socket from sliding, thereby improving the structural reliability of the electrical connector.

[0023] Optionally, the electrical connector further includes positioning plates, each positioning plate for fixing a set of terminals, the positioning plates being located in the area between the positioning protrusion and the main body.

[0024] By adopting the above technical solution, the positioning plate determines the relative spacing between several terminals and divides terminals of the same length of the fixing part into a group, thereby arranging the terminals in an orderly manner, which facilitates the fitting of the terminals with the receiving cavity to improve assembly efficiency; during the assembly and use of the electrical connector, relative displacement between a group of terminals is avoided, thereby improving the overall stability of the terminals and the stability of the electrical connector.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. During the electroplating process of the terminals, only the first protrusion and the second protrusion need to be electroplated, thus reducing the electroplating area and lowering costs; 2. The first contact arm and the second contact arm form a Y-shaped layout and tend to grip inward, so that the terminal applies stable contact pressure to the mating terminal during insertion and removal, thereby improving the stability of the connection; 3. The terminal has a simple and flat shape, which makes the manufacturing cost of the corresponding stamping die low and facilitates large-scale production. Attached Figure Description

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] Example 1 Please see Figure 1-2 The present application discloses a terminal 101, which includes a main body 11, a fixing part 12, and a contact part 13. The fixing part 12 is connected to one end of the main body 11, and the contact part 13 extends from the other end of the main body 11. A first contact arm 131 and a second contact arm 132 are symmetrically arranged about the centerline of the width direction of the main body 11 and form a Y-shape with the main body 11. The sides of the first contact arm 131 and the second contact arm 132 facing each other form a contact area for inserting mating terminals. A gap is formed between the first contact arm 131 and the second contact arm 132. The width of the gap gradually narrows from the direction close to the main body 11 to the direction away from the main body 11, so that the first contact arm 131 and the second contact arm 132 tend to grip each other inward, so that the terminal 101 applies stable contact pressure to the mating terminals during insertion and removal, thereby improving the reliability and stability of the connection.

[0030] The main body 11 is the main part of the terminal 101, providing structural support and electrical path. The shape and size of the main body 11 are determined according to the specific application scenario. It is usually designed to be simple to reduce production costs. For example, it can be a regular shape such as a cuboid to facilitate connection and assembly with other components.

[0031] Specifically, limiting portions 111 are formed on opposite sides of the main body 11. The limiting portions 111 cause the width of the main body 11 to vary, increasing the contact area and friction between the main body 11 and other components, thereby improving the stability of the terminal 101. The limiting portions 111 can be formed on the main body 11 by processes such as stamping, and their height and shape can be adjusted according to specific needs. In other embodiments, the limiting portions 111 can also adopt shapes such as strip protrusions to adapt to different assembly scenarios.

[0032] The fixing part 12 is used to fix the terminal 101 to the corresponding PCB so that the circuit connection forms a through-path. In this embodiment, the fixing part 12 is integrally formed with the main body 11 to ensure the continuity and conductivity of the terminal 101. The shape of the fixing part 12 needs to be designed according to the specific application scenario. For example, it can be a sheet for easy soldering to the PCB, or it can have a circular hole on its surface to cooperate with the corresponding structure on the PCB to fix the terminal 101.

[0033] Specifically, the fixing part 12 has positioning protrusions 121 on both sides. The positioning protrusions 121 can cooperate with the assembled components to position the fixing part 12 and improve the installation accuracy. The positioning protrusions 121 can be different shapes such as circular protrusions and square protrusions, and can be selected according to specific installation requirements.

[0034] In this embodiment, the fixing part 12 is set at a 90° angle to the main body part 11, and the width of the fixing part 12 is smaller than the width of the main body part 11, so that the terminals 101 are suitable for dense arrangement. For example, multiple terminals 101 can be arranged into groups. Since the fixing part 12 is set at a 90° angle to the main body part 11, different groups of terminals 101 can be arranged in a multi-layer array to form a stepped shape, so that the terminals 101 can be installed more densely in a limited space.

[0035] On the surface of the first contact arm 131 perpendicular to the side, a first protrusion 133 flush with the side is formed. On the surface of the second contact arm 132 perpendicular to the side, a second protrusion 134 flush with the side is formed. Electroplated layers are formed on the surfaces of the first protrusion 133 and the second protrusion 134. Both the first protrusion 133 and the second protrusion 134 can be integrally formed on the first contact arm 131 and the second contact arm 132. The first protrusion 133 and the second protrusion 134 establish an electrical connection between the terminal 101 and the mating terminal, enabling current conduction from the mating terminal to the terminal 101. Simultaneously, they enhance the contact pressure and friction between the terminal 101 and the mating terminal, improving contact stability.

[0036] When terminal 101 is inserted into mating terminal, the first contact arm 131 and the second contact arm 132 form an inward clamping tendency, thereby providing a stable clamping force and focusing it on the first protrusion 133 and the second protrusion 134. Furthermore, since the first protrusion 133 and the second protrusion 134 have small surface areas, they can provide extremely high pressure to the mating terminal, effectively breaking through any thin oxide layer that may exist on the contact surface with the mating terminal to form an airtight connection, thereby obtaining extremely low and stable contact resistance.

[0037] The combination of the main body 11, the fixing part 12, and the contact part 13 forms a complete terminal 101 structure. The main body 11 provides structural support and electrical path for the entire terminal 101, the fixing part 12 ensures that the terminal 101 can be stably mounted on a PCB or other conductor structure, and the contact part 13 contacts the mating terminal to transmit current or electrical signals. The close cooperation of the main body 11, the fixing part 12, and the contact part 13 enables the terminal 101 to effectively realize the electrical connection function.

[0038] Terminal 101 is typically made of a highly conductive metal, such as copper or copper alloys. Copper and copper alloys offer good strength and conductivity. The choice of material for terminal 101 depends on the electrical conditions and operating environment. Contact portion 13 usually requires electroplating to prevent oxygen corrosion and to smooth its surface, enhancing its mechanical and electrical properties. In this embodiment, the surfaces of the first protrusion 133 and the second protrusion 134 can be gold-plated or tin-plated. Because the surface areas of the first protrusion 133 and the second protrusion 134 are small, electroplating costs are saved while enhancing the conductivity stability of terminal 101.

[0039] In this embodiment, terminal 101 can be used in connectors for displays and smart home devices. Terminal 101 is generally sheet-like and has a simple shape, so it can be mass-produced by means of die stamping, etc. Terminal 101 does not have a complex three-dimensional curved surface structure, thereby reducing the difficulty of die production.

[0040] The implementation principle of this embodiment is as follows: The terminal 101 clamps the mating terminal through the Y-shaped layout formed by the first contact arm 131, the second contact arm 132 and the main body 11. The first protrusion 133 and the second protrusion 134 abut against the mating terminal to establish an electrical connection, so that the current passes through the first protrusion 133 and the second protrusion 134 to be conducted to the terminal 101. The fixing part 12 establishes an electrical connection between the terminal 101 and the PCB or other conductor structure, and the current is conducted to the PCB or other conductor structure, thereby establishing an electrical path between the mating terminal and the PCB or other conductor structure.

[0041] Example 2 Please see Figure 3-4 An electrical connector provided in this application includes multiple terminals 101, a socket 102, and a cover 103, wherein the multiple terminals 101 are not connected to each other.

[0042] Specifically, the socket 102 has multiple receiving cavities 21 extending through opposite sides of the socket 102. The multiple receiving cavities 21 are arranged in a multi-layer array, with adjacent layers forming a stepped shape. The cover 103 is slidably fitted with the socket 102 and has an array of through holes 31 on its surface. The contact portion 13 of the terminal 101 is inserted into the receiving cavity 21 and located in the receiving cavity 21. The fixing portion 12 of the terminal 101 extends out from the through hole 31. Thus, the cover 103 cooperates with the socket 102 to realize that multiple terminals 101 are housed inside the electrical connector and form a protective structure to prevent the terminals 101 from being affected by the external environment during the contact with mating terminals.

[0043] Specifically, the socket 102 can be made of insulating materials such as plastic, PBT, ABS, etc., preferably materials with good flame retardancy. The shape and size of the receiving cavity 21 match the shape of the terminal 101 to ensure that the terminal 101 can be accurately installed therein. The shape of the socket 102 needs to be set according to the usage scenario. For example, in this embodiment, the electrical connector can be used in the connector of the display screen, so the overall shape of the socket 102 can be a cuboid or a cube.

[0044] The cover 103 can fit tightly with the socket 102. The through hole 31 on the surface of the cover 103 is used for the fixing part 12 of the terminal 101 to pass through. The size and shape of the through hole 31 match the fixing part 12. The cover 103 can be connected to the socket 102 by means of snap-fit, adhesive or other methods to ensure the tightness of the connection. The material of the cover 103 can also be the same insulating material as the socket 102.

[0045] In this embodiment, a first stop 33 is formed on the surface of the cover 103 away from the fixing part 12, and a second stop 23 is provided at the bottom of the socket 102. The first stop 33 and the second stop 23 cooperate to restrict the socket 102 so as to accurately fit the cover 103 and prevent the socket 102 from sliding, thereby improving the structural reliability of the electrical connector.

[0046] Please see Figure 5 The cover 103 also includes a limiting baffle 32, each limiting baffle 32 corresponding to a row of through holes 31. After the corresponding terminal 101 is inserted into the through hole 31, it can abut against the limiting baffle 32, thereby positioning multiple rows of terminals 101 in groups through the limiting baffle 32. At the same time, one limiting baffle 32 corresponds to one row of through holes 31, and after the terminal 101 is inserted, it can abut against the limiting baffle 32 to ensure that the end of the contact part 13 is on the same tangential surface perpendicular to the surface of the receiving cavity 21, avoiding poor contact caused by the terminal 101 being inserted too deeply or too shallowly.

[0047] Please see Figure 6-8 The cover 103 has several through holes 31, and the terminals 101 corresponding to the through holes 31 are provided for the fixing part 12 to pass through. The through holes 31 can be tapered holes, thereby limiting the length of the fixing part 12 that can pass through the cover 103, so as to limit the axial movement of the terminal 101 and achieve reliable fixing. At the same time, it is compatible with positioning protrusions 121 within a certain size range, thereby reducing the processing accuracy requirements of the electrical connector, and allowing the cover 103 to disperse stress through the tapered surface of the through holes 31 when under force, avoiding damage caused by local stress concentration.

[0048] Specifically, the inner wall of the receiving cavity 21 is provided with a sliding groove. The terminal 101 is guided into the receiving cavity 21 by the sliding groove and the limiting part 111. At the same time, the side wall of the sliding groove provides support to the main body 11, thereby reducing the deformation of the terminal 101 caused by gravity.

[0049] The implementation principle of this embodiment is as follows: the socket 102 accommodates the main body 11 and contact part 13 of the terminal 101 through the receiving cavity 21, and the cover 103 causes the fixing part 12 of the terminal 101 to extend out from the through hole 31 to connect to the PCB or other conductor structure.

[0050] During the assembly of the electrical connector terminals 101, multiple terminals 101 with the same length of fixing parts 12 are grouped together. First, the main body 11 and contact part 13 of multiple terminals 101 are inserted into the corresponding multiple receiving cavities 21. After all terminals 101 are housed in the receiving cavities 21, the cover 103 is fitted onto the terminals 101, so that the fixing part 12 of the terminal 101 engages with the through hole 31 and abuts against the limiting baffle 32 of the cover 103. The through hole 31 stops the positioning protrusion 121 of the fixing part 12, limiting the length of the fixing part 12 entering the cover 103. Finally, the first stop 33 engages with the second stop 23 to accurately engage the cover 103 with the socket 102 and limit the relative movement of the cover 103 and the socket 102, thus realizing the assembly of the electrical connector terminals 101.

[0051] Example 3 Please see Figure 9 This embodiment is basically the same as embodiment 2, except that the multiple terminals 101 are connected to each other. In this embodiment, the electrical connector also includes a positioning plate 4, and the multiple terminals 101 are connected into a whole by the positioning plate 4. The positioning plate 4 is located in the area between the positioning protrusion 121 and the main body 11.

[0052] The positioning plate 4 determines the relative spacing between multiple terminals 101 and divides them into a terminal group according to the length of the fixing part 12 of the terminal 101, thereby arranging the terminals 101 in an orderly manner and facilitating the mating of the terminals 101 with the receiving cavity 21 to improve assembly efficiency. During the assembly and use of the electrical connector, the positioning plate 4 prevents the terminals 101 contained in the terminal group from being relatively displaced, thereby improving the overall stability of the terminals 101 and the stability of the electrical connector.

[0053] In this embodiment, the positioning plate 4 is made of plastic, such as NYLON66 or PC. In other embodiments, the surface of the positioning plate 4 may have heat dissipation holes to create an airflow circulation channel inside the electrical connector, thereby enhancing heat dissipation efficiency.

[0054] The implementation principle of this embodiment is as follows: During the manufacturing process of terminal 101, terminal 101 with the same length of fixing part 12 and main body part 11 is injection molded to form positioning plate 4 in the area between positioning protrusion 121 and main body part 11, so that terminal group is connected through positioning plate 4.

[0055] In the process of assembling the terminal 101 of the electrical connector, multiple terminals 101 with the same length fixing part 12 are first fixed in advance by the positioning plate 4 to form a terminal group. Then, the terminal group is directly inserted into the corresponding receiving cavity 21 of the socket 102 as a whole. Finally, the cover 103 is made to cooperate with the socket 102, thus completing the assembly of the terminal 101 of the electrical connector.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
