[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0033] In order to make the PIN pin removable, a plug hole is usually provided on the base, and a gap is left between the PIN pin and the plug hole. Since no sealing measures are taken at the connection between the PIN pin and the base, the waterproof performance of this type of connector is poor.

[0034] Based on this, the utility model proposes a PIN pin connector. In this solution, the PIN pin is inverted and plugged into the second plug hole and the first plug hole. In order to facilitate the sliding of the needle seat, a flexible seat is used to cooperate with it and fix it. In this way, the flexibility of the second plug hole on the flexible seat can be used to achieve gap-free fixation with the needle seat and ensure that the PIN pin has an excellent waterproof effect.

[0035] like Figure 1 - Figure 3 As shown, the PIN pin 300 connector is used to cooperate with the circuit board 10, including:

[0036] The base shell 100 is provided with a first plug hole 110, and the base shell 100 is spaced apart on one side of the circuit board 10;

[0037] The flexible seat 200 is fixed to the base shell 100 and is provided with a second plug hole 210 corresponding to the first plug hole 110; and

[0038] The PIN needle 300 is arranged to penetrate the first plug hole 110 and the second plug hole 210. The PIN needle 300 has a needle head 310 and a needle seat 320 relative to each other. The needle head 310 protrudes from the first plug hole 110 and is arranged close to the circuit board 10, and the needle seat 320 protrudes from the second plug hole 210.

[0039] In the technical solution adopted in this embodiment, the PIN pin 300 connector is used in conjunction with the circuit board 10 for power supply and communication connection with the electronic device. In order to improve the waterproofness of the PIN pin 300 connector, the PIN pin 300 connector in this solution includes two parts, a base shell 100 and a flexible seat 200, as a base for fixing the PIN pin 300, wherein the flexible seat 200 is fixedly mounted on the base shell 100, the base shell 100 is spaced apart from the circuit board 10, and the base shell 100 is provided with a first plug hole 110, and the flexible seat 200 is provided with a second plug hole 210 corresponding to the first plug hole 110; in addition, the PIN pin 300 has a relatively arranged The needle head 310 and the needle seat 320, the fixing method between the PIN pin 300 and the base is that the needle head 310 of the PIN pin 300 passes through the second plug hole 210 and the first plug hole 110 in sequence, and is set upside down, that is, the needle head 310 protrudes from the first plug hole 110 and is set close to the circuit board 10, so as to facilitate the abutment and cooperation with the circuit board 10; the needle seat 320 protrudes from the second plug hole 210, so as to compress the needle seat 320, and then compress the spring inside the PIN pin 300, so as to ensure the normal operation of the PIN pin 300. In this solution, in order to facilitate the sliding of the needle seat 320, a flexible seat 200 is used to cooperate and fix it. In this way, the flexibility of the second plug hole 210 on the flexible seat 200 can be used to achieve a gapless cooperation with the needle seat 320, and also ensure that the PIN pin 300 has an excellent waterproof effect.

[0040] Specifically, the shapes of the first plug hole 110 and the second plug hole 210 are not specifically limited. It can be understood that the second plug hole 210 is preferably the same shape as the needle seat 320, and the first plug hole 110 is preferably the same shape as the PIN pin 300, for example, it can be circular, or any other shape that matches it. It should be noted that the material of the flexible seat 200 is not specifically limited, for example, it can be plastic, or it can be a polyurethane elastomer, etc., as long as it can use its own elasticity to tightly cover the needle seat 320 of the PIN pin 300, so as to prevent external moisture from entering the inside of the PIN pin 300 from the gap. In addition, the PIN pin 300 in this embodiment is inverted on the base shell 100 and the flexible seat 200, so that it can effectively prevent external moisture and other liquids from entering the inside of the PIN pin 300 from the needle head 310, and further improve the waterproof effect of the PIN pin 300 connector.

[0041] Alternatively, if Figure 1 and Figure 3As shown, in one embodiment of the utility model, in order to improve the overall strength of the flexible seat 200, a covering portion 220 is further provided on the flexible seat 200. Preferably, the covering portion 220 is arranged on the periphery of the second plug hole 210, and protrudes and extends in a direction away from the first plug hole 110. The covering portion 220 is sleeved on the outer periphery of the needle seat 320, so that the matching part of the flexible seat 200 and the PIN needle 300 is extended, which can not only further improve the waterproof performance, but also assist the PIN needle 300 to smoothly complete the up and down sliding action.

[0042] Alternatively, if Figure 4 As shown, in one embodiment of the utility model, in order to facilitate the fixation of the flexible seat 200, a receiving cavity 120 is further provided on the base shell 100, the receiving cavity 120 is provided on the side of the base shell 100 away from the circuit board 10, and is communicated with the first plug hole 110, and the flexible seat 200 is fixedly provided in the receiving cavity 120. It should be explained that the cavity diameter of the receiving cavity 120 is slightly larger than the outer diameter of the flexible seat 200, so as to facilitate the fixing of the flexible seat 200 in the interior of the receiving cavity 120. Preferably, the internal shape of the receiving cavity 120 matches the outer shape of the flexible seat 200.

[0043] Alternatively, if Figure 4 As shown, in one embodiment of the utility model, in order to increase the force between the flexible seat 200 and the base shell 100, a mounting groove 121 is further provided in the accommodating cavity 120, and a mounting protrusion 230 is provided on the side of the flexible seat 200 facing the base shell 100. In this way, the flexible seat 200 and the base shell 100 can be fixed by the cooperation between the mounting protrusion 230 and the mounting groove 121.

[0044] Alternatively, if Figure 4 and Figure 5 As shown, in one embodiment of the utility model, in order to evenly disperse the force between the flexible seat 200 and the base shell 100, preferably, the mounting protrusion 230 and the mounting groove 121 are both arranged in a cross shape to ensure that there are forces in multiple different directions, thereby improving the connection strength between the flexible seat 200 and the base shell 100.

[0045] Alternatively, if Figure 4 and Figure 5As shown, in one embodiment of the utility model, in order to improve the assembly efficiency of the flexible seat 200 and the base shell 100, a limiting groove 123 may be further provided in the accommodating cavity 120, and a limiting protrusion 240 is provided on the side of the flexible seat 200 facing the base shell 100, and the limiting groove 123 and the limiting protrusion 240 are correspondingly arranged. In this way, when the flexible seat 200 and the base shell 100 are assembled, it is only necessary to place a plurality of limiting protrusions 240 in each limiting groove 123 in a one-to-one correspondence. It can be understood that the specific shapes of the limiting protrusion 240 and the limiting groove 123 are not specifically limited, for example, they can be round, square, etc.

[0046] Alternatively, if Figure 4 As shown, in one embodiment of the utility model, in order to facilitate the assembly of the PIN needle 300 connector with other components, the base shell 100 is further provided with a fixing portion 125, which is provided at the edge of the base shell 100 and extends in a direction away from the accommodating cavity 120. It should be noted that the shape of the fixing portion 125 is not specifically limited, as long as it can be assembled with other components.

[0047] Alternatively, if Figure 3 As shown, in one embodiment of the utility model, in order to make the PIN pin 300 have corrosion resistance, a metal layer is usually electroplated on the outside of the PIN pin 300, which can make the PIN pin 300 connector have corrosion resistance and reduce the resistance of the PIN pin 300. In this embodiment, in order to prevent the PIN pin 300 from being in contact with the circuit board 10 for a long time, causing the metal layer on its surface to be electrolyzed and lose its corrosion resistance, the PIN pin 300 connector also includes an elastic sleeve 400, which is sleeved on the outer periphery of the PIN pin 300 and abuts against the hole wall of the first plug hole 110. It should be explained that the elastic sleeve 400 in this embodiment can be an elastic tube or a spring. In this way, when the PIN pin 300 connector is working, the small spring inside the PIN pin 300 will be compressed first, and when the needle head 310 contacts the circuit board 10, the external elastic sleeve 400 needs to be compressed again, so that the needle tube of the PIN pin 300 contacts the circuit board 10, so that the contact time between the PIN pin 300 and the circuit board 10 can be shortened to avoid electrolysis. In addition, the provision of the external elastic sleeve 400 can also overcome the interference resistance between the PIN pin 300 and the base shell 100 , thereby facilitating the rebound and reset of the PIN pin 300 .

[0048] Alternatively, if Figure 3As shown, in one embodiment of the utility model, in order to facilitate fixing the elastic sleeve 400, the PIN pin 300 connector further includes a fixing seat 500, and the fixing seat 500 is sleeved on the outer periphery of the PIN pin 300 close to the circuit board 10 and abuts against the elastic sleeve 400. The fixing seat 500 in this embodiment can be a plunger or a nut, etc., as long as the elastic sleeve 400 can be fixed to the outside of the PIN pin 300 to ensure that the elastic sleeve 400 does not slide along the outer periphery of the PIN pin 300.

[0049] To achieve the above-mentioned purpose, the utility model also proposes an electronic device, which includes a device body and a PIN pin 300 connector. The specific structure of the PIN pin 300 connector refers to the above-mentioned embodiment. Since the electronic device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0050] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
