Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to PogoPin pins and PogoPin connectors. Background Art

[0002] With the rapid development of the new energy vehicle industry, the requirements for the internal electrical connection system of vehicles are also increasing day by day. In these systems, Pin connectors play a crucial role, and they are responsible for transmitting power, signals, and other electrical functions.

[0003] The PogoPin pin includes three basic components: a pin shaft, a spring, and a pin sleeve. Specifically, the pin shaft is inserted into the pin sleeve, and both ends of the spring are respectively connected to the pin shaft and the pin sleeve. The exposed end of the pin shaft is inserted into the connection end as the current output end, and the end of the pin sleeve away from the pin shaft is connected to the PCB / FPC as the current input end. In this way, the current sequentially passes through the pin sleeve, the spring, and the exposed end of the pin shaft and enters the display terminal of the vehicle (such as the vehicle instrument, the central control display screen, and other display devices).

[0004] In the related art, the applicant found that this kind of PogoPin pin is of a segmented structure. At the same time, with the increasing power of the display terminals carried by new energy vehicles, this requires the PIN connector to output a large current. However, because the PIN connector is restricted by the segmented design of the current output end and the current input and output ends, this design causes a large loss of current when passing through the PogoPin pin, resulting in the accumulation of heat and the reduction of efficiency, so that the current output by the connector cannot stably support the operation of the display terminal in a large current state.

[0033] Please refer to Figures 1 to 4 , the PogoPin needle proposed by the present utility model includes:

[0034] An integrated needle shaft 10, the integrated needle shaft 10 is provided with a current output end and a current input end, the current input end is used to connect to the circuit board 40, and the current output end is used to connect to the electrical interface;

[0035] A needle sleeve 20, slidably sleeved on the integrated needle shaft 10, the current output end and the current input end are exposed outside the needle sleeve 20; and

[0036] A spring 30, the spring 30 is arranged inside the needle sleeve 20, and both ends are respectively connected to the integrated needle shaft 10 and the needle sleeve 20.

[0037] In the technical solution of the present utility model, the PogoPin needle adopts the integrated needle shaft 10 to form a non-segmented current path. In this way, the current directly flows from the current input end of the integrated needle shaft 10 to the current output end, thereby avoiding the problem of current loss caused by heat generation due to resistance, achieving the purpose of passing a large current, and thus improving the power to ensure the stable operation of the display terminal.

[0038] The integrated pin shaft 10 is a straight rod-shaped current conductor with a non-segmented current output end and a current input end. The current input end is used to connect to the circuit board 40, and the current output end is used to connect to an electrical interface. Among them, the current input end is connected to the circuit board 40 of the PogoPin connector by means of soldering or SMT automatic chip mounting process, etc., so as to achieve electrical conduction. The output end is in a round head shape and is used to connect to an in-vehicle display terminal. Of course, it can be understood that in addition to the display terminal, the connector applying this PogoPin pin can also be used as an electrical interface and a power-on port to achieve electrical connection with electronic devices other than the display terminal, meeting the multi-functional usage scenarios. In this way, current is transmitted from the current input end of the integrated pin shaft 10 to the current output end. During this process, the resistance of the transmission circuit is the resistance value of a single conductor, which can avoid current loss and stabilize the output power, thereby realizing an in-vehicle display terminal that can stably maintain a relatively large power in a large-current output form and ensuring the operation stability of the corresponding device.

[0039] Specifically, the PogoPin pin is integrally inserted into the pin sleeve 20 so that the current output end and the current input end of the integrated pin shaft 10 are exposed outside the pin sleeve 20. It can be understood that the PogoPin pin can slide relative to the pin sleeve 20 along the length direction of the pin sleeve 20. A spring 30 is arranged between the integrated pin shaft 10 and the pin sleeve 20, and the two ends are respectively connected to the integrated pin shaft 10 and the pin sleeve 20. In this way, when the current output end of the integrated pin shaft 10 receives extrusion from the display terminal, the spring 30 provides a reverse acting force to prevent the integrated pin shaft 10 from detaching from the electrical interface of the display terminal or preventing the connection with the electrical interface of the display terminal from becoming loose, effectively preventing the instantaneous disconnection problem between the PogoPin connector and the display terminal. It can be understood that when the PogoPin pin is in the working state, the pin sleeve 20 is fixed by the interface end carrier 50 of the external electrical interface. At this time, only the PogoPin pin can move relative to the pin sleeve 20 in the direction away from the electrical interface. During this process, the pin sleeve 20 is in a stationary state relative to the electrical interface.

[0040] Furthermore, as Figures 2 to 4As shown, the needle sleeve 20 is provided with a movable channel 20a, and the integrated needle shaft 10 is slidably inserted in the movable channel 20a, wherein the integrated needle shaft 10 is provided with a first stop portion 11 near the current output end, and the needle sleeve 20 is provided with a second stop portion 21 near the current input end, and the two ends of the spring 30 are respectively connected to the side of the first stop portion 11 facing the current input end and the side of the second stop portion 21 facing the circuit output end. In this way, when the current output end is squeezed by external force, the integrated needle shaft 10 as a whole is away from the external electrical interface. At this time, the spring 30 is compressed and deformed because one end of the spring 30 is connected to the second stop portion 21 fixed relative to the integrated needle shaft 10. At this time, the spring 30 is restored under the action of elastic potential energy, and the spring 30 pushes the integrated needle shaft 10 in the opposite direction toward the external electrical interface through the first stop portion 11, thereby avoiding or reducing the instantaneous disconnection problem.

[0041] In one embodiment of the present invention, Figure 2 As shown, a stop buckle 22 is provided at one end of the needle sleeve 20 close to the current output end. The stop buckle 22 and the needle sleeve 20 are an integral structure. The shape of the stop buckle 22 is adapted to the shape of the needle sleeve 20. The stop buckle 22 is provided with a penetration opening, which is connected to the active channel 20a; the stop buckle 22 abuts against the side of the first stop portion 11 facing the current output end, so that the integrated needle shaft 10 can be prevented from actively moving toward the external electrical interface. At the same time, the position of the stop buckle 22 is limited to stop the maximum sliding of the integrated needle shaft 10, thereby locking the integrated needle shaft 10 in the active channel 20a of the needle sleeve 20.

[0042] Further, if Figure 3 As shown, the first stop portion 11 and the second stop portion 21 are both annular structures. In this way, by increasing the contact area between the spring 30 and the first stop portion 11 and the second stop portion 21, and matching the PogoPin needle, it is convenient to install multiple devices.

[0043] In one embodiment of the present invention, Figure 4 As shown, the end of the first stop portion 11 close to the current output end forms a guide section, and the cross-section of the guide section gradually becomes smaller from the end away from the current output end to the end close to the current output end, so that the guide section forms a first snap-fitting slope 11a; the side of the stop buckle 22 facing the first stop portion 11 forms a second snap-fitting slope 22a, and the first snap-fitting slope 11a is connected to the second snap-fitting slope 22a. In this way, the area between the first stop portion 11 and the stop buckle 22 is effectively increased, and the limiting stability is improved.

[0044] In one embodiment of the present invention, the integrated needle shaft 10 and the needle sleeve 20 are both made of brass. Brass is a conductive alloy of copper and zinc with high mechanical strength and hardness, which makes the PogoPin needle more durable when subjected to pressure and impact. At the same time, it has certain advantages in anti-magnetism and economic cost.

[0045] In an embodiment of the present utility model, the outer surfaces of the integrated needle shaft 10 and the needle sleeve 20 are provided with an electroplating enhancement layer. Through the electroplating enhancement layer, the corrosion resistance and electrical conductivity of the integrated needle shaft 10 and the needle sleeve 20 can be improved.

[0046] Furthermore, in an embodiment, the electroplating enhancement layer is a gold plating layer. Among them, the electroplating enhancement layer composed of gold is at least a bilayer or more hierarchical structure. Specifically, after a primary electroplating process is completed on the surfaces of the integrated needle shaft 10 and the needle sleeve 20, a gold plating layer is formed. Subsequently, a primary electroplating process or any number of electroplating processes are carried out again, so as to form multiple gold plating layers on the surfaces of the integrated needle shaft 10 and the needle sleeve 20. In another embodiment, the electroplating enhancement layer is composed of conductive metals such as gold, nickel, copper, silver, and aluminum. At least two of the conductive metals can be selected to form the electroplating enhancement layer on the surfaces of the integrated needle shaft 10 and the needle sleeve 20. During the electroplating process, at least two electroplating processes are carried out, so as to form a multi-layered electroplated composite layer on the surfaces of the integrated needle shaft 10 and the needle sleeve 20.

[0047] In an embodiment of the present utility model, as Figure 4 shown, the PogoPin needle is provided with a plug-in section 12 at the current input end. The cross-sectional area of the plug-in section 12 is smaller than the cross-sectional areas of other conductive sections of the PogoPin needle. In this way, a primary step structure is formed at the current input end of the PogoPin needle, so as to facilitate the plug-in section 12 for inserting the circuit board 40 and improve the installation stability.

[0048] The present utility model also proposes a PogoPin connector, which includes a circuit board 40 and a PogoPin needle. Among them, the specific structure of the PogoPin needle refers to the above-mentioned embodiment. Since the PogoPin connector proposed by the present utility model adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.

[0049] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present utility model.
