Description

Technical Field

[0001] This utility model relates to the field of circuit boards, and more specifically, it relates to a limiting structure for a circuit board and a power socket. Background Technology

[0002] A circuit board is a basic component used for mechanical support and connection of electronic components. It is usually made of non-conductive substrate material, and conductive lines are etched on the circuit board by chemical or mechanical methods to connect different electronic components.

[0003] The power socket is one of the electronic components on the circuit board. The bottom of the power socket has several pins. These pins are inserted into soldering holes on the circuit board. The outer edge of the soldering holes has solder pads. A soldering iron is used to solder the pins to the solder pads, thus connecting the power socket's circuitry to the circuitry within the circuit board. Excess pins are then trimmed. After soldering, the power socket and circuit board are connected solely by pins. During subsequent circuit board testing, the power cord needs to be inserted into the power socket and the circuit board tested. If the circuit board is tested frequently, the power cord will be inserted and removed from the power socket many times. During this process, the power socket may vibrate back and forth. Excessive force during insertion and removal may loosen the pins.

[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 limiting structure for circuit boards and power sockets.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a limiting structure for a circuit board and a power socket, including a substrate and a power socket, wherein the substrate is provided with a plurality of soldering holes, the power socket is provided with pins for passing through the soldering holes, a limiting plate is provided on one side of the power socket, an elongated groove is formed on the substrate, and two abutments for inserting into the elongated groove are provided on one side of the limiting plate, the two abutments restricting the forward and backward movement of the power socket by respectively abutting against the front and rear inner walls of the elongated groove, and the limiting plate is transparent.

[0007] The present invention is further configured such that: the abutting member includes two locking strips, the two locking strips can approach each other, and a locking block is fixed at the end of each locking strip facing away from the limiting plate, and the side of the locking block facing the locking strip is used to abut against one side of the substrate.

[0008] The present invention is further configured such that the side of the card block facing away from the card strip is an arc surface, and the side of the card block facing the card strip is a horizontal surface.

[0009] The present invention is further configured such that: the limiting plate has several grooves on the side facing away from the card strip, and the arc surface of the card block is covered with a flexible pad.

[0010] The present invention is further configured such that: the elongated groove is located at a corner position near the substrate, and the limiting plate is located on the side of the power socket near the substrate.

[0011] The present invention is further configured such that the distance between the two abutting members is at least half the length of the long groove.

[0012] In summary, this utility model has the following beneficial effects:

[0013] Two contact pieces located on the limiting plate are embedded in the elongated slot, and each contact piece abuts against the front and rear inner walls of the slot. This allows the power socket to restrict its forward and backward movement during insertion and removal by contacting the inner walls of the slot, thus greatly reducing the amount of forward and backward wobbling and minimizing the possibility of pin loosening, ensuring pin safety. There is a relatively large light-transmitting area between the two contact pieces, allowing light to pass through the slot and the transparent limiting plate into the viewer's eyes. The transparent limiting plate facilitates the alignment of the contact pieces within the slot, thereby simplifying operation. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A limiting structure for a circuit board and a power socket, such as Figure 1 and Figure 4As shown, the device includes a substrate 1 and a power socket 2. The substrate 1 has several solder holes 3, and the power socket 2 has pins 4 for passing through the solder holes 3. A limiting plate 5 is provided on one side of the power socket 2, and the lower side of the limiting plate 5 is flush with one side of the substrate 1. A long groove 6 is formed on the substrate 1, and two abutments for inserting into the long groove 6 are provided on one side of the limiting plate 5. There is a gap between the two abutments. The two abutments restrict the forward and backward movement of the power socket 2 by abutting against the front and rear inner walls of the long groove 6 respectively. After each pin 4 is passed through the corresponding solder hole 3, the two abutments on the limiting plate 5 will be embedded in the long groove 6 and will abut against the front and rear inner walls of the long groove 6 respectively. Thus, during subsequent insertion and removal of the power socket 2, the abutments restrict the power supply by abutting against the inner walls of the long groove 6. The forward and backward movement of socket 2 greatly reduces the amplitude of back-and-forth wobbling of power socket 2, thereby reducing the possibility of pin 4 loosening and ensuring the safety of pin 4. Since the diameter of the existing welding holes 3 is larger than that of pin 4, pin 4 can be easily inserted into the welding holes 3. This means that even when all pins 4 are inserted into the corresponding welding holes 3, power socket 2 can still move to some extent. Therefore, people still need to align the position of the contact parts. The limiting plate 5 is transparent and the distance between the two contact parts is at least half the length of the long groove 6. This setting provides a relatively large light-transmitting area between the two contact parts, allowing light to enter people's eyes through the long groove 6 and the transparent limiting plate 5. The transparent limiting plate 5 makes it easy for people to align the position of the contact parts in the long groove 6, thus facilitating operation.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the abutment includes two locking strips 7 that can approach each other. The length of the locking strips 7 along the length direction of the long groove 6 is greater than the length of the locking strips 7 along the width direction of the long groove 6. This makes the locking strips 7 less prone to deformation along the width direction of the long groove 6, but they can deform to a certain extent along the width direction of the long groove 6 under a certain external force. Each of the two locking strips 7 has a locking block 8 fixed to its opposite end facing the limiting plate 5. The side of the locking block 8 facing the locking strip 7 is used to abut against one side of the base plate 1. When the locking strip 7 is fully inserted into the long groove 6, the locking block 8 protrudes from the other side of the base plate 1 and one side of the locking block 8 abuts against the base plate 1, thereby preventing the abutment from detaching from the long groove 6. This arrangement enables the power supply to... The pre-fixation of socket 2 and substrate 1 makes it difficult for power socket 2 to move up and down when soldering pins 4, which facilitates subsequent soldering. The side of the locking block 8 facing away from the locking strip 7 is an arc surface, and the side of the locking block 8 facing the locking strip 7 is a horizontal surface. When the locking block 8 needs to be inserted into the long slot 6, the outer edge of the long slot 6 will abut against the arc surface of the locking block 8, which will generate a force between the two locking strips 7, thus bringing the two locking strips 7 closer together, and in turn bringing the two locking blocks 8 closer together, so that the two locking blocks 8 can enter the long slot 6. When the locking block 8 passes out of the long slot 6, the two locking strips 7 will return to their original position, so that the water surface of the locking block 8 abuts against one side of the substrate 1, so that the locking block 8 has a limiting effect on the power socket 2.

[0022] like Figure 1 and Figure 3 As shown, the limiting plate 5 has several grooves 9 on the side facing away from the locking strip 7. The arc surface of the locking block 8 is covered with a flexible pad 10. Because the locking strip 7 can deform to a certain extent in the width direction of the long groove 6, if a force is accidentally generated in the left and right direction during the insertion and removal process, the power socket 2 will still shake to a certain extent. Therefore, people can further limit the shaking of the power socket 2 by holding one hand on the limiting plate 5 and the lower side of the base plate 1, and use the other hand to plug and unplug the power cord. The grooves 9 can increase the friction between the hand and the limiting plate 5. The flexible pad 10 makes the arc surface of the locking block 8 relatively soft, so that the locking block 8 is not easy to scratch people. The long groove 6 is set near the corner of the base plate 1. The limiting plate 5 is located on the side of the power socket 2 near the side of the base plate 1. The limiting plate 5 is close to the edge of the base plate 1, so that people will not be interfered with by other electrical components when holding the limiting plate 5. The base plate 1 is made of epoxy resin, which ensures the overall strength and life of the base plate 1.

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.
