Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and more particularly to a plug-in circuit board. Background Art

[0002] A circuit board is a basic component used to support and connect electronic components. It is a plate-like object with conductive lines covered on an insulating substrate. It is used to transmit electrical signals in electronic devices. The wires on the circuit board are usually formed by printing, etching or other processing techniques. These wires connect various electronic components, such as capacitors, resistors, integrated circuits, etc., to form a complete circuit system.

[0003] Existing circuit boards are provided with connectors, some of which are pin interfaces (such as the USB2.0 interface on a computer motherboard). Some external electronic devices or components are connected to the connectors through connectors. By inserting the pins into the connectors, the circuit board is connected to the external electronic device or component. When the circuit board is squeezed or collided, if the pins of the connector are bent, it will make it impossible to install the connector of the external electronic device on the connector.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0008] The present invention is further configured as follows: the cross section of the buckle is triangular, the bottom surface of the buckle is horizontal, and the buckle can block the opening of the slot.

[0009] The utility model is further configured as follows: a plurality of clamping holes are opened on the base plate, and a clamping column is fixedly connected to the protective shell.

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

[0020] A plug-in circuit board, such as Figures 1 to 3As shown, it includes a substrate 1, a plug-in connector 2 is fixedly connected to the substrate 1, and a connector 3 is detachably connected to the plug-in connector 2. The connector 3 is a connection port for an external electronic device or electronic component. The connection with the circuit board is achieved by fixing the connector 3 on the plug-in connector 2. A protective shell 4 is fixedly connected to the substrate 1, and the protective shell 4 surrounds the plug-in connector 2. A clip 5 for fixing the connector 3 is integrally formed on the protective shell 4, and a buckle 6 is integrally formed on the clip 5. By arranging the plug-in connector 2 on the substrate 1, when the connector 3 is connected to the plug-in connector 2, the circuit board can be used normally, and the protective shell 4 is arranged on the substrate 1, so as to protect the plug-in connector 2. At the same time, a clip 5 is arranged on the protective shell 4, and after the buckle 6 on the clip 5 is engaged with the connector 3, the connector 3 remains connected to the plug-in connector 2. The protective shell 4 is made of TPU material, which has good wear resistance and improves the life of the protective shell 4.

[0021] like Figure 2 and Figure 3 As shown, the card strip 5 has elastic deformation characteristics. The card strip 5 can be deformed in the direction away from the protective shell 4. A slot for inserting the connector 3 is provided in the center of the protective shell 4. The cross section of the buckle 6 is triangular. The bottom surface of the buckle 6 is horizontal and the buckle 6 can block the opening of the slot. The connector 3 is inserted from the slot to achieve connection with the plug-in connector 2. When the connector 3 is connected to the plug-in connector 2, the card strip 5 will deform and bend. When the connector 3 is completely stuck to the plug-in connector 2, the card strip 5 is restored to its original shape, so that the buckle 6 can be stuck to the top of the connector 3 to achieve fixation of the connector 3. The cross section of the buckle 6 is triangular, so that the connector 3 remains fixed on the plug-in connector 2 and is not easy to fall out of the slot. The cross section of the buckle 6 is triangular, so that when the connector 3 is clipped to the plug-in connector 2, the connector 3 can contact the inclined surface of the buckle 6, so that the connector 3 can exert a force on the card strip 5 to achieve the bending of the card strip 5, and there is no need for the operator to manually pull the card strip 5, thereby simplifying the fixing effect of the buckle 6 on the connector 3. The bottom surface of the buckle 6 is horizontal, ensuring that when the top surface of the connector 3 contacts the bottom surface of the buckle 6, the buckle 6 has a better limiting effect on the connector 3.

[0022] like Figure 2 and Figure 3As shown, two clamping holes 7 are provided on the base plate 1, and two clamping posts 8 are integrally formed on the protective shell 4, so that when the clamping posts 8 are clamped into the clamping holes 7, the connection between the protective shell 4 and the base plate 1 is realized, and two reinforcing posts 9 are fixedly connected to the clamping posts 8. The two reinforcing posts 9 are inclined, and the maximum distance between the two reinforcing posts 9 is greater than the diameter of the clamping holes 7. The distance between the end points of the two reinforcing posts 9 away from the clamping posts 8 is the maximum distance between the two reinforcing posts 9. When the clamping posts 8 pass through the clamping holes 7, the reinforcing posts 9 can also pass through the clamping holes 7. The reinforcing posts 9 can prevent the clamping posts 8 from falling off from the clamping holes 7, thereby improving the fixing effect of the protective shell 4 on the base plate 1, and the reinforcing posts 9 have elasticity. The card strip 5 and the card post 8 are integrally formed on the protective shell 4, so the card strip 5 and the reinforcing column 9 are also made of TPU material. Since the TPU material has good elasticity, the card strip 5 and the reinforcing column 9 are elastic. When the protective shell 4 is installed on the substrate 1, the operator first aligns the card post 8 with the card hole 7, and then the operator presses the protective shell 4 down. During this process, the reinforcing column 9 on the card post 8 is elastically deformed after being squeezed by the substrate 1, so that the reinforcing column 9 also passes through the card hole 7. When the reinforcing column 9 completely passes through the card hole 7, the reinforcing column 9 restores the elastic deformation, which has a fixing effect on the protective shell 4.

[0023] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
