Description

Technical Field

[0001] This utility model relates to the field of circuit boards, and more specifically, to a circuit board with pin headers. Background Technology

[0002] Circuit boards are the support and electrical connection carriers for electronic components. Through printing technology, conductive lines, pads, etc. are printed on an insulating substrate to connect and fix electronic components, forming a complete circuit system.

[0003] A pin header is a type of connector on a circuit board, typically consisting of multiple metal pins arranged in a single or double row. Submodules are connected to the pin header via connecting wires. However, the pin header has a relatively small diameter, making it susceptible to bumps and knocks during circuit board transportation and handling, which can affect the integrity of the pin header.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a circuit board with pin headers.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a circuit board with pin headers, including a substrate, a base fixedly connected to the substrate, a plurality of pin headers fixedly on the top surface of the base, two protective seats fixedly connected to the substrate and fitting against the base, a plurality of protective plates provided on the top surface of the protective seats, the protective plates on the two protective seats surrounding all the pin headers, the protective plates being able to move up and down along the length direction of the pin headers, and a limiting member being provided on the protective plate, the limiting member being able to limit the protective plate to the highest position.

[0007] The present invention is further configured such that: the top surface of the protective base is provided with a plurality of sliding grooves, the protective plate is slidably connected to the sliding grooves, the protective plate is provided with a rotating groove on the side facing away from the pin header, and the limiting member is a limiting strip rotatably connected in the rotating groove, the limiting strip being able to rotate out of the rotating groove.

[0008] The present invention is further configured such that: a torsion spring is provided on the limiting strip, the torsion spring provides the limiting strip with the force to rotate out of the rotating groove, and when the torsion spring is in the natural state, the angle between the limiting strip and the side wall of the protective plate is 30 degrees.

[0009] The present invention is further configured such that: an extension column is fixedly connected to one end of the limiting strip facing away from the rotation point, the extension column is located on the side of the limiting strip facing away from the protective seat, and a receiving groove communicating with the rotation groove is also provided on the protective plate, the receiving groove being used to receive the extension column.

[0010] The present invention is further configured such that the limiting strip has a plurality of friction patterns.

[0011] The present invention is further configured such that: the protective plate has a flange on the side facing away from the pin header.

[0012] The present invention is further configured such that: a mounting hole is provided on the substrate, and the protective seat is fixed to the substrate by a screw located in the mounting hole.

[0013] In summary, this utility model has the following beneficial effects:

[0014] When installing the submodule, the protective plate at the pin header location is slid down to expose the space around the pin header, facilitating the installation of the submodule. In the normal state or after the wiring has been installed, the protective plate is slid up to the limit position and limited by a limiting component. At this time, the protective plate protects the pin header, preventing it from being impacted. The impact is borne by the protective plate and the protective base, making the pin header and base less susceptible to damage and preventing the pin header from bending or the base from detaching from the substrate.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A circuit board with pin headers, such as Figure 1 and Figure 2As shown, the device includes a base plate, a base 1 fixedly connected to the base plate, a plurality of pins 2 fixedly fixed to the top surface of the base 1, and two protective seats 3 fixedly connected to the base plate and fitting against the base 1. The top surface of each protective seat 3 is provided with a plurality of protective plates 4, which surround all the pins 2. The protective plates 4 can move up and down along the length of the pins 2. When the protective plate 4 moves to its highest position, its top surface is above the pins. The protective plates 4 are also provided with limiting members that can limit them to their highest position. The cross-sections of both protective seats 3 are C-shaped, and both protective seats 3 surround the base 1. Mounting plates are provided on the outer sides of both protective seats 3. Mounting holes are provided on the base plate, and the protective seats 3 are fixed to the base plate by screws located in the mounting holes. The screws pass through the mounting holes and the mounting plates. Nuts are used for fixing, thus ensuring the fixing strength of the two mounting bases. When installing the submodule, the protective plate 4 at the position where the pin header 2 needs to be installed is slid down, thereby exposing the space around the pin header 2, which facilitates the installation of the submodule. In the normal state or after the wiring has been installed, the protective plate 4 is slid upward to the limit position and is limited by the limit component. At this time, the protective plate 4 protects the pin header 2, so that the pin header 2 is not impacted. The impact is borne by the protective plate 4 and the protective base 3, so that the pin header 2 and the base 1 are not easily affected, preventing the pin header 2 from bending and the base 1 from detaching from the substrate. There are multiple protective plates 4, so that the corresponding protective plate 4 can be slid according to the required installation position. The overall area of ​​the protective plate 4 is small, which reduces the force required when sliding.

[0020] like Figure 1 and Figure 2As shown, the top surface of the protective base 3 has several sliding grooves. The protective plate 4 is slidably connected to the sliding grooves. The protective plate 4 has a rotating groove 5 on the side facing away from the pin header 2. The limiting member is a limiting strip 6 rotatably connected in the rotating groove 5. The limiting strip 6 can rotate out of the rotating groove 5. The protective plate 4 slides along the depth direction of the sliding groove. When the protective plate 4 is moved upward to the limiting position, the rotating groove 5 on the protective plate 4 is just exposed outside the sliding groove. At this time, the limiting strip 6 is flipped out of the rotating groove 5, so that the limiting strip 6 can restrict the protective plate 4 from sliding back into the sliding groove. A torsion spring is provided on the limiting strip 6. The torsion spring provides the force for the limiting strip 6 to rotate out of the rotating groove 5. When the torsion spring is in its natural state, the limiting strip 6 can rotate out of the rotating groove 5. The angle between the limiting strip 6 and the side wall of the protective plate 4 is 30 degrees. The torsion spring allows the limiting strip 6 to rotate out of the rotating groove 5 under the driving action of the torsion spring the instant the rotating groove 5 is exposed. This eliminates the need for manual rotation of the limiting strip 6, and the rotation angle is relatively small, making it easy for people to apply force to rotate the limiting strip 6 back into the rotating groove 5. An extension column 7 is fixedly connected to the end of the limiting strip 6 facing away from the rotation point. The extension column 7 is located on the side of the limiting strip 6 facing away from the protective seat 3. The protective plate 4 also has a receiving groove 8 that communicates with the rotating groove 5. The receiving groove 8 is used to receive the extension column 7. The extension column 7 is designed to provide a point of force for people to drive the limiting strip 6 to rotate, thus facilitating operation.

[0021] like Figure 1 and Figure 2 As shown, the limiting strip 6 has several friction patterns. During the up-and-down sliding of the protective plate 4, the limiting strip 6 is located in the sliding groove and abuts against the inner wall of the sliding groove under the force of the torsion spring. The friction patterns increase the friction between the limiting strip 6 and the inner wall of the sliding groove, so that the protective plate 4 can be limited to a certain extent when sliding to any position. The protective plate 4 has a flange 9 on the side facing away from the pin header 2. One side of the flange 9 is flush with the top surface of the protective plate 4. The flange 9 provides a force position for people to pull the protective plate 4 out of the sliding groove. The substrate is made of epoxy resin, which ensures the life and strength of the circuit board.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
