Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a connector. Background Art

[0002] PCB connector, also known as printed circuit board connector or PCB connector, is a type of electronic connector, specially used for connecting and fixing printed circuit boards (PCB). PCB connector is a device mounted on PCB to transmit signals or power from one PCB to another, or from another source within the unit to or from the PCB.

[0003] In existing connector technology, especially when the male and female connectors are plugged together, if the male end is in an extremely offset state, the PIN of the male end may hit the spring in the female connector, causing the so-called "PIN collapse". This phenomenon refers to the PIN or spring being damaged, deformed or broken due to excessive pressure or improper contact during the contact process between the PIN and the spring, thus affecting the electrical performance and service life of the connector. Utility Model Content

[0004] The purpose of the present application is to provide a PCB connector that can prevent the male end from being in an extremely offset state when inserted into the connector, thereby avoiding the PIN collapse of the PCB connector.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A connector comprises a connector body, the cross section of the connector body is in the shape of a "J", the front side and the rear side of the connector body are respectively provided with a first air avoidance groove, each of the first air avoidance grooves is provided with a spring piece portion, the left and right sides of the two spring piece portions are respectively connected to the connector body through a connecting bridge, the lower sides of the two spring piece portions are respectively provided with a first contact portion, the middle parts of the two spring piece portions are provided with a second air avoidance groove, the tops of the two second air avoidance grooves are connected to each other, and the bottoms of the two second air avoidance grooves are extended upward to form a second contact portion.

[0007] Furthermore, the first contact portion is located below the second contact portion.

[0008] Furthermore, the two first contact portions are symmetrically shaped like figures of eight.

[0009] Furthermore, the two second contact portions are symmetrically inverted in an eight-shaped shape.

[0010] Furthermore, welding parts are respectively provided on the front and rear sides of the bottom of the connector body, and the welding parts and the connector body are perpendicular to each other.

[0011] Furthermore, a welding groove is provided on the side of the welding portion.

[0012] Furthermore, the bottom side surfaces of the two first air-avoiding grooves are respectively provided with guide portions, and the guide portions are arranged to be inclined upward.

[0013] Furthermore, the two guide portions are symmetrically shaped like an inverted figure eight.

[0014] Furthermore, the front side surface and the rear side surface of the connector body are respectively provided with limiting protrusions.

[0015] The beneficial effects of this application are:

[0016] (1) The first escape grooves on the front and rear sides of the connector body of the present application are provided with spring parts, which are connected to the connector body through a connecting bridge. This design allows the spring part to have a certain amount of movement space when subjected to the pressure of the male PIN position, thereby preventing the spring part from being damaged or deformed due to direct force; in addition, the left and right sides of the spring part of the present application are respectively connected to the connector body through connecting bridges, which not only enhance the stability of the spring part, but also enable the spring part to maintain a certain degree of elasticity when subjected to the pressure of the PIN position, further reducing the risk of "PIN collapse".

[0017] (2) A second air-avoiding groove is provided in the middle of the two spring pieces of the present application. The tops of the second air-avoiding grooves are interconnected, and the bottoms extend upward to form a second contact portion. This design allows the second contact portion to provide a certain amount of tolerance when the male PIN position contacts the spring piece, even if the male PIN position is slightly offset, thereby reducing the possibility that the PIN position directly hits the spring piece.

[0018] (3) The present application adopts the design of the "J"-shaped main body, the coordination of the first air-avoiding groove and the spring sheet portion, and the arrangement of the second air-avoiding groove and the second contact portion, so that the entire connector has both structural stability and certain elasticity. This design enables the connector to maintain a certain deformation capacity when subjected to external force, thereby reducing the "PIN collapse" phenomenon caused by external force.

[0019] (4) The connector of the present application has another significant feature, that is, there is no need to set a plastic shell or a rubber core to limit the male PIN. In traditional connector design, in order to ensure the correct alignment of the PIN position and prevent it from excessive movement, auxiliary components such as a plastic shell or a rubber core are usually used to limit the male PIN. However, this design not only increases the manufacturing cost and complexity of the connector, but may also affect the electrical performance and reliability of the connector due to material problems of the plastic or rubber core.

[0030] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, a connector includes a connector body 1, which passes through a mounting slot on a PCB board 2 and is welded to the bottom of the PCB board 2 through a welding portion 3 at the bottom. The connector of this embodiment is a female end, and the male end is inserted into the female end from the bottom of the PCB board 2.

[0032] like Figure 2As shown, the connector body 1 of this embodiment is made of a right metal material by stamping and has elasticity. The cross-section of the connector body 1 is in a U-shape, which is the surface seen from the left side or the right side. First clearance grooves 4 are respectively formed on the front side and the rear side of the connector body 1. A spring piece part 5 is arranged in each first clearance groove 4, and the spring piece part 5 can move relatively or in opposite directions in the first clearance groove 4. When the male end is inserted, the spring piece parts 5 move in opposite directions, that is, the spring piece part 5 on the front side moves forward and the spring piece part 5 on the rear side moves backward. When the male end leaves the connector body 1, the spring piece part 5 on the front side moves backward and the spring piece part 5 on the rear side moves forward. The left side and the right side of the two spring piece parts 5 are respectively connected to the connector body 1 through connection bridges 6. First contact parts 51 are respectively arranged on the lower sides of the two spring piece parts 5. Second clearance grooves 52 are arranged in the middle parts of the two spring piece parts 5. The tops of the two second clearance grooves 52 communicate with each other, and the bottoms of the two second clearance grooves 52 extend upward to form second contact parts 53.

[0033] As Figure 3 As shown, first clearance grooves 4 are respectively formed on the front side and the rear side of the connector body 1 of this embodiment. A spring piece part 5 is arranged in each groove, and these spring piece parts 5 can move relatively or in opposite directions in the first clearance grooves 4. When the male end is inserted obliquely forward, the spring piece part 5 on the front side will move forward synchronously and adaptively adjust its position to cope with the pressure of the male end PIN position. This design allows the spring piece part 5 to have a certain amount of movement space when subjected to the pressure of the male end PIN position, thus avoiding damage or deformation of the spring piece due to direct force. In addition, the left side and the right side of the two spring piece parts 5 are respectively connected to the connector body 1 through connection bridges 6. The connection bridges 6 not only enhance the stability of the spring piece parts 5, but also enable the spring piece parts 5 to maintain a certain elasticity when subjected to the PIN position pressure, further reducing the risk of "PIN collapse". A second clearance groove 52 is also arranged in the middle part of the two spring piece parts 5. Its top communicates with each other, and the bottom extends upward to form a second contact part 53. This design further disperses the pressure and reduces the direct impact on the spring piece part 5. Therefore, even when the male end is inserted obliquely, the connector can effectively ensure that the spring piece part 5 will not collapse PIN, showing excellent stability and reliability.

[0034] As Figure 3 As shown, in this embodiment, the first contact part 51 is located below the second contact part 53. The contact area between the first contact part 51 and the male end is larger than the contact area between the second contact part 53 and the male end. The first contact part 51 can ensure stable and uniform contact with the male end. This design not only enhances the electrical connection performance between the connector and the male end, but also helps to disperse the pressure of the PIN position on the spring piece part 5.

[0035] As Figure 5As shown, in this embodiment, the two first contact portions 51 are symmetrically shaped like a figure eight. The figure eight design ensures the balance and symmetry of the connector in physical structure, which helps the connector to remain stable during insertion and removal, and reduces deformation or damage caused by uneven force.

[0036] The figure-eight-shaped first contact portion 51 can provide a larger and more uniform contact area, and form a more stable electrical connection with the male end. This design can ensure that the connector maintains good contact performance during long-term use.

[0037] When the male end is inserted into the connector at different angles, the eight-shaped contact design can better adapt to this change and reduce damage to the connector caused by angle deviation. This adaptability improves the fault tolerance and service life of the connector.

[0038] like Figure 5 As shown, in this embodiment, the two second contact portions 53 are symmetrically inverted in an eight-shaped shape. The eight-shaped design provides a wider channel for the PIN needle to withdraw. When the male end withdraws, the PIN needle can slide out smoothly along the two sides of the eight-shaped shape, reducing the possibility of jamming and friction, thereby making it easier to withdraw.

[0039] like Figure 2 As shown, in this embodiment, the front and rear sides of the bottom of the connector body 1 are respectively provided with welding parts 3, and the welding parts 3 are perpendicular to the connector body 1. The vertically arranged welding parts 3 make it easy to weld the connector to the circuit board. The welding parts 3 are perpendicular to the connector body 1, which makes the welding process more stable, reduces the welding difficulty, and improves the installation efficiency.

[0040] like Figure 2 As shown, in this embodiment, a welding groove 31 is provided on the side of the welding portion 3. The welding groove 31 provides a clear positioning point and an additional welding material attachment area for the welding process. This helps to ensure that the welding process is more stable and reliable, and reduces the risk of poor welding.

[0041] like Figure 2 As shown, in this embodiment, the bottom side surfaces of the two first avoidance grooves 4 are also provided with guide portions 7, and the guide portions 7 are arranged obliquely upward. The design of the guide portions 7 obliquely upward can effectively guide the insertion direction of the male PIN needle. During the insertion process, the guide portions 7 can provide a clear path to ensure that the PIN needle can accurately enter the socket inside the connector.

[0042] The inclined design of the guide portion 7 can reduce the resistance of the PIN during the insertion process. Since the guide portion 7 is inclined upward, the PIN will gradually enter the socket along the inclined surface during insertion, thereby reducing the required insertion force.

[0043] The existence of the guide portion 7 can help prevent the PIN from being inserted incorrectly. Even if the PIN is slightly deviated during insertion, the guide portion 7 can guide the PIN back to the correct insertion path through its inclined design, thereby avoiding the occurrence of incorrect insertion.

[0044] like Figure 2 As shown, in this embodiment, the two guide portions 7 are symmetrically inverted in the shape of a figure eight.

[0045] like Figure 2 As shown, in this embodiment, the front side and the rear side of the connector body 1 are respectively provided with limit protrusions 11. By limiting the position of the connector body 1, the limit protrusions 11 help to enhance the connection stability between the connector and the PCB board 2. This can reduce the risk of connection loosening or failure caused by environmental factors such as vibration, impact or temperature changes.
