[0002] As is known to all, electrical connectors are widely used in electronic products to realize electrical connection between electronic components and meet the requirements of charging and discharging or data transmission.

[0003] Among them, for electrical connectors that have the function of preventing impurities such as sweat, water and dust from entering, for example, a probe connector disclosed in Chinese patent application No. 202120731183.X, although the probe connector can prevent impurities such as water, sweat and dust from entering to ensure the reliability of the work. However, since the tail end face of the needle is directly abutted against the reset piece, this results in a large assembly length of the existing probe connector, which cannot be adapted to more sophisticated and smaller electronic devices. At the same time, since the needle needs to be processed with an inner groove for the seal to be set, this increases the turning process of the needle and correspondingly reduces the production efficiency. Furthermore, since the seal is disc-shaped, the shape of the seal is relatively complex, which brings processing difficulties.

[0024] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0025] See also Figures 1 to 3 The electronic connector 100 of the utility model comprises a pin shaft 10, a spring 20, a conductive seat body 30 having a receiving cavity 31 and a cavity opening 32, and a sealing ring 40 located in the receiving cavity 31 and adjacent to the cavity opening 32. The cavity opening 32 penetrates the head end face 33 of the conductive seat body 30. Figure 1 In the embodiment, as an example, the cavity opening 32 is a circular opening, so as to facilitate the processing and manufacturing of the cavity opening 32 on the conductive seat body 30; obviously, in other embodiments, the cavity opening 32 can also be designed as an elliptical opening or a regular polygonal opening, etc., as long as the designed shape of the cavity opening 32 does not affect the normal sliding of the needle shaft 10, so it is not necessary to Figure 1The needle shaft 10 is built into the receiving cavity 31, and the head end 11 of the needle shaft 10 can extend from the cavity opening 32 or retract into the conductive seat body 30 to slide. The needle shaft 10 is provided with an assembly cavity 13 that penetrates the tail end face 121 of the needle shaft 10 and communicates with the receiving cavity 31. The outer side 41 of the sealing ring 40 is sealed with the conductive seat body 30 to prevent impurities such as sweat, water and dust from entering from the matching position between the outer side 41 of the sealing ring 40 and the conductive seat body 30 and contacting the spring 20; the inner side 42 of the sealing ring 40 is sealedly sheathed on the needle shaft 10, so that the inner side 42 of the sealing ring 40 and the needle shaft 10 are sealed, thereby preventing impurities such as sweat, water and dust from entering from the matching position between the inner side 42 of the sealing ring 40 and the needle shaft 10 and contacting the spring 20. The head end 21 of the spring 20 is placed in the assembly cavity 13, and the head end 21 of the spring 20 is also in contact with the needle shaft 10; the tail end 22 of the spring 20 extends out of the assembly cavity 13 and is in contact with the conductive seat 30; the spring 20 provides a reset force for the automatic reset of the needle shaft 10, and when the needle shaft 10 contacts an external electronic device, the spring 20 keeps the needle shaft 10 in close contact with the external electronic device. More specifically, as follows:

[0026] like Figure 3 As shown, as an example, the outer side 41 of the sealing ring 40 is also fixedly connected to the conductive seat body 30, and the inner side 42 of the sealing ring 40 is also slidably connected to the needle shaft 10; this design makes the sealing ring 40 and the conductive seat body 30 in a stationary state relative to the needle shaft 10, so as to simplify the structure of the sealing ring 40. Obviously, in other embodiments, the outer side 41 of the sealing ring 40 can also be slidably connected to the conductive seat body 30, and correspondingly, the inner side 42 of the sealing ring 40 is fixedly connected to the needle shaft 10; this design makes the sealing ring 40 slide relative to the conductive seat body 30 with the needle shaft 10, which can also simplify the structure of the sealing ring 40. When the sealing ring 40 is made to slide with the needle shaft 10, the receiving cavity 31 of the conductive seat body 30 needs to meet the travel requirement of the sealing ring 40 sliding with the needle shaft 10. In addition, according to actual needs, the outer side of the sealing ring can also be fixedly connected to the conductive seat body 30, and the inner side of the sealing ring can be fixedly connected to the needle shaft 10. At this time, a telescopic adjustment structure is required between the outer and inner sides of the sealing ring to meet the need for the inner side of the sealing ring to slide relative to the outer side of the sealing ring together with the needle shaft 10. At this time, the specific structure of the sealing ring can refer to a probe connector disclosed in Chinese patent application No. 202120731183.X.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, as an example, the conductive seat body 30 includes a sleeve 30a and a needle tube 30b which are fixed to each other; the receiving cavity 31 is formed on the needle tube 30b and the sleeve 30a, and the cavity diameter of the receiving cavity 31 on the sleeve 30a is larger than the cavity diameter of the receiving cavity 31 on the needle tube 30b. Figure 5 As shown; the cavity 32 passes through the head end surface 33 of the sleeve 30a; at this time, the outer side 41 of the sealing ring 40 is sealed and clamped between the needle tube 30b and the sleeve 30a; the tail end 12 of the needle shaft 10 is located in the accommodating cavity 31 of the needle tube 30b, and the tail end 22 of the spring 20 is in contact with the needle tube 30b. Therefore, with the help of the conductive seat 30 including the sleeve 30a and the needle tube 30b that are fixed to each other, the assembly operation of the needle shaft 10, the spring 20 and the sealing ring 40 on the conductive seat 30 is more convenient, and the structure of the outer side 41 of the sealing ring 40 being fixedly connected to the conductive seat 30 is simplified. More specifically, in Figures 3 to 5 In the embodiment, as an example, the sleeve 30a is sleeved on the head end 34 of the needle tube 30, and a fixing lug 361 is provided on the side wall 36 of the needle tube 30b, and an engaging groove 351 which is interference fit with the fixing lug 361 is provided on the side wall 35 of the sleeve 30a, so that the sleeve 30a and the needle tube 30b are assembled together through interference fit by means of the interference fit between the fixing lug 361 and the engaging groove 351, thereby improving the convenience of assembling and fixing the sleeve 30a and the needle tube 30b; obviously, in other embodiments, the engaging groove 351 can be provided on the side wall 36 of the needle tube 30b, and correspondingly, the fixing lug 361 can be provided on the side wall 35 of the sleeve 30a, so that the purpose of assembling the sleeve 30a and the needle tube 30b through interference fit can also be achieved, so it is not necessary to use the embodiment. Figures 3 to 5 Limits shown.

[0028] In order to simplify the manufacturing process of the fixing lug 361 on the needle tube 30b while ensuring the reliability of the fixing between the sleeve 30a and the needle tube 30b, the fixing lug 361 is designed to be annular so that the fixing lug 361 extends a full circle on the needle tube 30b. Figure 6 As an example, the fixing lug 361 is provided with a chamfered structure 3612 for tilting the head end 3611 of the fixing lug 361. In order to make the outer side 41 of the sealing ring 40 more reliably fixed by the conductive base 30, Figure 3 As an example, the end face 341 of the needle tube 30b is perpendicular to the axis C of the needle shaft 10, the side wall 311 of the receiving cavity 31 on the sleeve 30a is parallel to the axis C of the needle shaft 10, and the end wall 312 of the receiving cavity 31 on the sleeve 30a is inclined outward relative to the axis C in the direction close to the axis C of the needle shaft 10. At this time, the outer side 41 of the sealing ring 40 is respectively in contact with the side wall 311, the end wall 312 and the end face 341 of the needle tube 30b, and the state is shown in FIG. Figure 3 shown.

[0029] like Figure 3 and Figure 7 As shown, as an example, the cavity section 131 of the assembly cavity 13 adjacent to the tail end face 121 of the needle shaft 10 has a cavity diameter that is gradually increased along the direction from the head end 11 to the tail end 12 of the needle shaft 10 (i.e., the direction indicated by arrow A), so as to facilitate the operation of installing the head end 21 of the spring 20 into the needle shaft 10, facilitate the telescopic deformation of the spring 20 relative to the needle shaft 10, and avoid the defect of increased radial size of the needle shaft 10 due to the cavity diameter of the entire assembly cavity 13 being arranged in an increasing manner.

[0030] like Figure 3 As an example, the inner side 42 of the sealing ring 40 is sleeved on the shaft section 14 of the needle shaft 10 between the head end 11 and the tail end 12 of the needle shaft 10, and the tail end 12 of the needle shaft 10 also radially protrudes from the shaft section 14, so that the sealing ring 40 blocks the tail end 12 when the needle shaft 10 extends out of the conductive seat body 30 by a preset distance, thereby effectively preventing the needle shaft 10 from accidentally falling off the conductive seat body 30. In addition, the assembly cavity 13 extends to the head end 11 of the needle shaft 10 to effectively extend the length of the assembly cavity 13, and correspondingly increase the length of the spring 20 installed in the needle shaft 10, thereby effectively shortening the total assembly length of the spring 20 and the needle shaft 10, and further effectively shortening the total assembly length of the electronic connector 100 of the utility model. In addition, the sealing ring 40 is in a circular shape to simplify the structure and manufacturing process of the sealing ring 40. Specifically, in Figure 3 and Figure 7 As an example, the shaft segment 14 is a straight segment to facilitate the smooth sliding of the shaft segment 14 relative to the inner side 42 of the sealing ring 40.

[0031] Compared with the prior art, since the needle shaft 10 is provided with an assembly cavity 13 that penetrates the tail end face 121 of the needle shaft 10 and communicates with the receiving cavity 31, and the head end 21 of the spring 20 is placed in the assembly cavity 13 and abuts against the needle shaft 10, and the tail end 22 of the spring 20 extends out of the assembly cavity 13 and abuts against the conductive seat body 30, such a design allows a part of the spring 20 to be accommodated in the needle shaft 10, thereby shortening the total assembly length of the spring 20 and the needle shaft 10, thereby shortening the total assembly length of the electronic connector 100 of the present invention, so that the electronic connector 100 of the present invention can be adapted to more sophisticated and smaller electronic devices.

[0032] It should be supplemented that the electronic connector 100 of the present invention can be applied to wearable products such as watches, bracelets, Bluetooth headsets and VR, and when the electronic connector 100 of the present invention is used, its needle shaft 10 is connected to an electronic device, and its conductive seat 30 (specifically the needle tube 30b) is connected to another electronic device.

[0033] The above disclosure is only a preferred example of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
