Description

Technical Field

[0001] The utility model relates to the field of connectors, specifically to connectors. Background Art

[0002] A connector is an important component used to connect electronic devices or circuit boards. Its main function is to transfer power, signals, and data from one electronic device or circuit board to another. The connector can connect the electronic components on the circuit board, enabling the transmission of current and signals. This is the most basic and important function of the connector. In addition to electrical connection, the connector can also provide a mechanical fixing function, firmly fixing the electronic components on the circuit board to prevent them from loosening or shaking, thereby ensuring the stability and reliability of the device. Connectors are widely used in various electronic devices, such as computers, communication devices, consumer electronic products, industrial automation devices, etc. In these devices, the role of connectors is very important. They not only affect the function and operation of the device but also directly relate to the performance and reliability of the device. There are many types of connectors, which can be classified into various types according to different classification criteria. For example, according to the connection method, they can be divided into plug connectors and socket connectors; according to the type of signal transmitted, they can be divided into signal connectors and power connectors; according to the shape and structure, they can be divided into circular connectors, rectangular connectors, board-to-board connectors, etc.

[0003] The existing connectors still have the following defects: during the process of installing the connector onto the circuit board, the pins cannot be effectively fixed, and it is easy for the pins to be misaligned, loosened, or deformed. During installation, the connector is fixed by pressing. Due to excessive pressing force or incorrect direction, the pins may be misaligned, loosened, or deformed. After the pins are deformed, they cannot align with the reserved mounting holes on the circuit board, resulting in difficulty in installing the connector onto the circuit board, reducing the stability of the pins, making it impossible for the pins to accurately insert into the reserved holes on the circuit board, and inconvenient for installing the connector. In addition, after the circuit board and the connector are fixed, injecting glue is a common method to enhance the connection stability. The glue is evenly poured into the connection part between the circuit board and the connector. However, during the glue injection process, since there is no structure on the connector to prevent the glue from overflowing, when too much glue is injected, the glue easily overflows along the connector, causing the glue to enter the interior of the connector, easily contaminating the circuit board and other components of the connector, and affecting the potting effect. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art solutions, the utility model provides a connector, which can effectively solve the technical problems that the existing connectors cannot fix the pins, the pins are prone to misalignment, loosening, and deformation during use, and the glue is prone to overflow when the connector is injected with glue.

[0005] The technical solution adopted by the present utility model to solve its technical problems is as follows: A connector, including a docking end and a mounting end. Inside the docking end and the mounting end, there are several pins. One end of the pin extends to the insertion end, and the other end of the pin extends to the power connection end. A fixing member is provided at one end of the pin close to the power connection end. There are several positioning holes on the fixing member for mating and inserting the pins. The number and spacing of the positioning holes are the same as those of the several pins. A rubber baffle is provided between the docking end and the mounting end. The edge of the rubber baffle extends outwards and extends beyond the side surface of the mounting end. A limiting plate extends outwards from the side surface of the power connection end. A positioning groove for fixed installation is formed between the rubber baffle and the limiting plate.

[0006] Further, one end of the limiting plate far from the docking end extends vertically outwards to form a fixing plate, and a positioning post perpendicular to the fixing plate is provided on the fixing plate.

[0007] Further, the end of the positioning post far from the fixing plate is conical.

[0008] Further, a protruding limiting strip is provided on the side surface of the positioning post.

[0009] Further, one end of the limiting plate far from the docking end forms a triangular support portion, and one end of the support portion is connected to the fixing plate.

[0010] Further, a guiding post and a clamping tooth in the same extending direction as the pin are provided on the side surface of the docking end.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the connector of the present utility model, by setting the fixing member and the positioning holes, the stability of the pins at the power connection end is ensured.

Specific implementation manner

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Such as Figures 1 - 12As shown, the connector includes a docking end 1 and a mounting end 2. Inside the docking end 1 and the mounting end 2, there are several pins 3. One end of the pin 3 extends to the insertion end, and the other end of the pin 3 extends to the power connection end. In this embodiment, the specific number of pins 3 is 18. The several pins 3 are divided into two groups, and the two groups of pins 3 are equally spaced and arranged. One end of the pin 3 close to the mounting end 2 is bent at 90 degrees. When the connector is fixed to the circuit board, the several pins 3 are respectively inserted into the reserved holes on the circuit board, and the pins 3 are fixed to the circuit board by soldering. One end of the pin 3 close to the power connection end is provided with a fixing member 4. The fixing member 4 is provided with several positioning holes 6 for mating and inserting the pins 3. The number and spacing of the positioning holes 6 are the same as the number and spacing of the several pins 3. The docking end 1, the mounting end 2, and the fixing member 4 are specifically made of plastic material. The specific number of the positioning holes 6 is 18. The positioning holes 6 are respectively matched with the several pins 3. By providing the fixing member 4 and the positioning holes 6, insertion points are provided for the pins 3, effectively preventing the pins 3 from being misaligned, loosened, or deformed during assembly or use. A glue baffle 7 is provided between the docking end 1 and the mounting end 2. The edge of the glue baffle 7 extends outwards and extends beyond the side surface of the mounting end 2. When the connector is installed on the circuit board, the connector is further fixed by injecting glue into the glue baffle 7. The glue baffle 7 can block the glue, prevent the glue from overflowing, prevent the glue from flowing out along the surface of the docking end 1, and avoid the glue flowing into the inside of the connector. The side surface of the power connection end extends outwards to form a limiting plate 8. A positioning groove 9 for fixed installation is formed between the glue baffle 7 and the limiting plate 8. When the connector is installed on the circuit board, the positioning groove 9 is snapped into the metal frame by pressing. The clamping position of the metal frame is snapped into the positioning groove 9 to fix the connector and the circuit board.

[0028] One end of the limiting plate 8 away from the docking end 1 extends vertically outwards to form a fixing plate 10. The fixing plate 10 is provided with positioning posts 14 perpendicular to the fixing plate 10. The end of the positioning post 14 away from the fixing plate 10 is conical. The side surface of the positioning post 14 is provided with a protruding limiting strip 5. By providing the positioning posts 14, the connector can be quickly and accurately positioned and fixed during the installation process, simplifying the installation steps. By providing the fixing plate 10 and the positioning posts 14, the stability and fixing property of the connector are further enhanced. The positioning posts 14 serve as additional fixing points, which can ensure that the connector remains stable when subjected to external forces and is not easily loosened or detached. During use, the positioning posts 14 are snapped into the reserved holes on the circuit board. The conical design makes it easier for the positioning posts 14 to align and smoothly enter the holes during insertion, reducing the installation difficulty. The limiting strip 5 increases the friction between the positioning posts 14 and the reserved holes, improving the stability of the positioning posts 14 during the installation process.

[0029] One end of the limiting plate 8 away from the docking end 1 forms a triangular support portion 11. One end of the support portion 11 is connected to the fixing plate 10. The triangular support portion 11 enhances the structural strength of the limiting plate 8 and the fixing plate 10, enabling them to withstand greater external forces and impacts.

[0030] On the side surface of the docking end 1, there are guide posts 13 and locking teeth 12 having the same extending direction as that of the pins 3. The guide posts 13 and the locking teeth 12 provide guiding and locking functions for the docking process of the connector. The guide posts 13 help the connector to be quickly and accurately positioned during docking, while the locking teeth 12 ensure that the connector can be firmly locked after docking and is not easily separated. Specifically, there are two guide posts 13, and the locking teeth 12 are located in the middle of the side surface of the docking end 1. The two guide posts 13 are symmetrically distributed with respect to the center line of the locking teeth 12.

[0031] For the connector of this embodiment, by providing the fixing member 4 and the positioning holes 6, the stability of the pins 3 at the power connection end is ensured. The fixing member 4 and the positioning holes 6 provide insertion points for the pins 3, effectively preventing the pins 3 from being misaligned, loosened or deformed during assembly or use. By providing the glue blocking plate 7, it effectively prevents the glue from overflowing during the assembly process and avoids the glue flowing into the interior of the connector. During use, several pins 3 are respectively inserted into the holes reserved on the circuit board, and the pins 3 are fixed on the circuit board by soldering. The positioning posts 14 are snapped into the holes reserved on the circuit board. After the connector is installed on the circuit board, the connector is further fixed by injecting glue into the glue blocking plate 7. The glue blocking plate 7 prevents the glue from overflowing. Finally, by pressing, the positioning groove 9 is snapped into the metal frame, and the engaging position of the metal frame is snapped into the positioning groove 9 to fix the connector and the circuit board on the metal frame.
