Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to TV horizontal power supply terminals. Background Technology

[0002] In the field of electronic equipment manufacturing, especially in electronic products such as televisions (TVs), power terminals are key components that connect PCB boards to external power sources (or wires), and their stability is crucial for the normal operation of the equipment. As electronic products continue to develop towards miniaturization, lightweighting, and high performance, the layout of electronic components on PCB boards is becoming increasingly dense, which places higher demands on the installation stability of power terminals.

[0003] Existing power terminals have significant shortcomings in practical applications. Most traditional terminals rely solely on soldering the pins to the PCB board for fixation, lacking effective lateral support and protective structures. When electronic products are subjected to vibration, impact, or other external forces during transportation and use, the terminals are prone to tilting and shifting on the PCB board. For example, during the production and transportation of televisions, they may undergo multiple handling and vibration cycles. In such cases, existing power terminals may be unable to withstand the external forces and shift in position, leading to loose connections with the PCB board, affecting the reliability of electrical connections, and consequently causing equipment malfunctions such as poor power contact and signal transmission interruptions, severely impacting product quality and user experience. Therefore, a horizontal TV power terminal is provided to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a TV horizontal power terminal to address the shortcomings of the existing technology, thereby solving the technical problem that existing terminals are prone to tilting and shifting under external force after being installed on the PCB board.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] TV horizontal power terminal includes a terminal body with pins formed for insertion into and soldering to a PCB board, the pins having a plurality of pins extending in the same direction; a plug portion is formed on the side of the terminal body, and a plastic sleeve is included for insertion into the plug portion to support and protect the terminal body mounted on the PCB board.

[0007] Furthermore, there is a pair of pins, and the ends of each pin are connection terminals with rounded corners.

[0008] Further, the terminal body is formed with a first leg and a second leg that are electrically connected after contacting the PCB board, and the first leg and the second leg extend in opposite directions; a first bending portion is formed between the first leg and the terminal body, and the first bending portion makes the extending direction of the first leg perpendicular to the extending direction of the pin. A second bending portion is formed between the second leg and the terminal body, and the second bending portion (4) makes the extending direction of the second leg perpendicular to the extending direction of the pin.

[0009] Further, both the first leg and the second leg are disposed between a pair of pins.

[0010] Further, the terminal body, the first leg, the second leg and a plurality of pins are integrally formed.

[0011] Further, the plastic sleeve includes a support portion in a "C" shape. A sleeve body is provided inside the support portion, and the sleeve body is formed with a slot for the insertion portion to be inserted. A notch for the insertion portion to be inserted into the slot is formed on the side or the top of the sleeve body; when the insertion portion is inserted into the slot, the side wall of the insertion portion and the inner wall of the slot are in interference fit.

[0012] Further, a guiding bevel for guiding the insertion portion is formed at the notch, and a positioning bevel cooperating with the guiding bevel is formed on the side of the insertion portion.

[0013] Further, an anti - toppling portion for increasing the contact area with the surface of the PCB board is provided at the bottom of the support portion.

[0014] Further, the anti - toppling portion is a sheet body extending in opposite directions, and the extending direction is parallel to the thickness direction of the terminal body.

[0015] Further, the sleeve body is formed with a relief groove for facilitating the connection between the insertion portion inserted into the slot and a wire, and a wiring hole is formed on the insertion portion.

[0016] The beneficial effects of the present utility model: After inserting the pins on the terminal body into the through - holes on the PCB board and welding them to the PCB board by welding to achieve electrical connection, the installation of this power terminal can be realized. However, before installing the terminal body on the PCB board, first insert the insertion portion on the terminal body into the plastic sleeve, and then install the terminal body with the plastic sleeve on the PCB board. At the same time, the plastic sleeve closely adheres to the surface of the PCB board, and the plastic sleeve supports the side of the terminal body. When the terminal body is subjected to an external force, under the support of the plastic sleeve, a protective effect is achieved, so that it will not be toppled or displaced, improving the stability of this power terminal after being installed on the PCB board.

[0022] The following is a detailed description of the TV horizontal power terminal of this utility model with reference to the accompanying drawings.

[0023] like Figure 1 As shown, an embodiment of the TV horizontal power terminal of this utility model includes a terminal body 1. The terminal body 1 is formed with pins 2 for insertion into and soldering to a PCB board. Each pin 2 has a pair extending in the same direction, and the end of each pin 2 is a connecting end 21 with rounded corners. By rounding the connecting ends 21, the pins 2 on the terminal body 1 can be accurately inserted into through holes on the PCB board. After insertion, the connecting ends 21 are soldered to the PCB board, and an electrical connection is established, thus enabling the installation of this power terminal. Furthermore, depending on the PCB board model, the pins 2 can be set to a pair or more to adapt to different PCB board models, improving the practicality of this power terminal.

[0024] Furthermore, the terminal body 1 is formed with a first leg 31 and a second leg 41 that are electrically connected after contacting the PCB board. Both the first leg 31 and the second leg 41 are positioned between a pair of pins 2 and extend in opposite directions. A first bend 3 is formed between the first leg 31 and the terminal body 1, making the extension direction of the first leg 31 perpendicular to the extension direction of the pin 2. A second bend 4 is formed between the second leg 41 and the terminal body 1, making the extension direction of the second leg 41 perpendicular to the extension direction of the pin 2. When the pins 2 on the terminal body 1 are inserted into the PCB board, both the first leg 31 and the second leg 41 contact the PCB board and are electrically connected upon contact. After power is applied, the combined action of the first leg 31, the second leg 41, and several pins 2 enables the power terminal to conduct a larger current, improving the power-on efficiency. Furthermore, by placing the first pin 31 and the second pin 41 between the two pins 2, the power terminal becomes more compact, saving space after it is mounted on the PCB board. In addition, the extension length of the first pin 31 and the second pin 41 is 2mm. With the first pin 31 and the second pin 41 extending in opposite directions, they can also play a certain limiting role on the installed terminal body 1. When there is no force, the power terminal is always in a horizontal position.

[0025] Secondly, the terminal body 1, the first support 31, the second support 41, and several pins 2 are integrally molded, which not only simplifies the manufacturing process but also reduces costs and improves efficiency. The terminal body 1 has a plug-in portion 6 formed on its side. This power terminal also includes a plastic sleeve 5 for plugging into the plug-in portion 6 to protect the terminal body 1. Before mounting the terminal body 1 on the PCB board, the plug-in portion 6 on the terminal body 1 is first plugged into the plastic sleeve 5. Then, the terminal body 1 with the plastic sleeve 5 is mounted on the PCB board, and the plastic sleeve 5 is tightly attached to the PCB board surface. When the terminal body 1 is subjected to external force, the plastic sleeve 5 provides support, achieving a protective effect and preventing it from tilting or shifting. Furthermore, the thickness of the terminal body 1, the plug-in portion 6, and the pins 2 are all uniform, at 0.8mm.

[0026] The plastic sleeve 5 includes a "U"-shaped support portion 51, within which a sleeve body 52 is provided. The sleeve body 52 has a slot 53 for inserting the connector 6, and a groove 54 is formed on the side of the sleeve body 52 to allow the connector 6 to be inserted into the slot 53. The connector 6 on the terminal body 1 is inserted into the slot 53 through the groove 54 on the side of the sleeve body 52, so that the side wall of the connector 6 is press-fitted with the inner wall of the slot 53, achieving the insertion effect and preventing the connector 6 from automatically disengaging from the slot 53. Furthermore, after the terminal body 1 is mounted on the PCB board, the bottom of the support portion 51 is in close contact with the surface of the PCB board, providing side support for the terminal body 1 and achieving a limiting effect. Alternatively, the groove 54 can be located at the top of the sleeve body 52, allowing the connector 6 to be inserted into the slot 53 through the groove 54 at the top of the sleeve body 52, which also provides support and limiting effects.

[0027] A guide bevel 55 is formed at the slot 54 to guide the insertion part 6. A positioning bevel 62 is formed on the side of the insertion part 6. The positioning bevel 62 also guides and positions the insertion part 6. With the cooperation of the positioning bevel 62 and the guide bevel 55, the insertion part 6 can be inserted into the slot 53 more accurately, which improves the convenience of insertion.

[0028] The bottom of the support 51 is provided with an anti-tipping part 57 to increase the contact area with the PCB board surface. The anti-tipping part 57 is a sheet extending in the opposite direction, and the extension direction is parallel to the thickness direction of the terminal body 1. After the terminal body 1 is installed on the PCB board, the anti-tipping part 57 at the bottom of the support 51 contacts the surface of the PCB board. Under the action of the anti-tipping part 57, the contact area between the support 51 and the PCB board surface is increased. The extension direction of the anti-tipping part 57 is the same as the direction of its width. The width of the anti-tipping part 57 is 7mm, and the width of the support 51 is 5.5mm. The width of the anti-tipping part 57 is greater than the width of the support 51, so that the center of gravity of the plastic sleeve 5 is at its bottom. This not only improves the stability of the plastic sleeve 5 itself, but also improves the anti-tilting effect after being subjected to force.

[0029] Additionally, the sleeve 52 is formed with a relief groove 56 to facilitate the connection of the plug portion 6 into the slot 53 and the wire. The plug portion 6 is formed with a wiring hole 61, the diameter of which is 2mm. After the plug portion 6 is inserted into the slot 53, the relief groove 56 exposes the wiring hole 61 on the plug portion 6, making it easy to connect to the wire. Under the action of this power terminal, the wire is electrically connected to the PCB board.

[0030] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0031] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
