While FIG. 6 illustrates the portion of the structure of the first end 321 disposed through the second bore segment, and the sidewall of the portion of the structure of the first end 321 disposed through the second bore segment abutting the second wall 1012, it is understood that in other embodiments, the portion of the structure of the first end 321 disposed through the second bore segment may have a gap with the second wall 1012. In one embodiment, the second wall 1012 may be omitted, that is, the second hole segment may be omitted, in which case the first wall 1011 is disposed between the inner surface 110 and the outer surface 120 and intersects with the inner surface 110 and the outer surface 120, and part of the first end 321 is disposed through the first hole segment, and the sidewall thereof abuts against or is spaced apart from the first wall 1012.

In a specific installation process, the elastic thimble 320 may be firstly inserted into the pinhole 101, when the elastic thimble 320 extends into the pinhole 101 to the limit position and the second end 322 protrudes from the outer surface 120 through the pinhole 101, the limit protrusion 3211 contacts with the inner surface 110, the elastic thimble 320 is stable, at this time, the through hole 311 of the circuit board 310 is aligned with the first end 321, so that the first end 321 is inserted into the through hole 311, thereby the first end 321 can be conveniently welded with one side of the circuit board 310 departing from the limit protrusion 3211, the elastic thimble 320 can be firmly fixed on the circuit board 310, good electrical contact between the elastic thimble 320 and the circuit board 310 is ensured, and effective implementation of a charging process is facilitated.

It should be noted that, in each embodiment of the present application, the second end 322 is disposed through the pinhole 101 and protrudes out of the outer surface 120, and the second end 322 is used for being matched with the conductive terminal 13 of the wearable device 10, so as to charge the wearable device 10. Second end 322 is capable of extending and retracting relative to first housing 100 along the extending direction of needle hole 101, for example, elastic spike 320 may be a POGO PIN (POGO PIN), in which case first end 321 may be understood as a needle tube, second end 322 may be understood as a needle shaft, a spring is disposed in the needle tube, and the needle shaft is connected to the spring in the needle tube, so that the needle shaft is capable of extending and retracting relative to first housing 100 along the extending direction of needle hole 101.

Even if the second end 322 abuts against the intersection line formed by the intersection of the first wall 1011 and the outer surface 120, the second end 322 is in line contact or point contact with the intersection line, and the frictional resistance between the two is small enough, so that the expansion and contraction of the second end 322 are not affected, and the charging reliability can be ensured after the conductive terminal 13 of the wearable device 10 is matched with the second end 322.

In one embodiment, the flexible needle 320 may be, for example, a pogo needle, and the first end 321 may be a needle tube, and the second end 322 may be a needle shaft, and the spring is disposed in the needle tube, and the needle shaft is connected to the spring in the needle tube, so that the needle shaft can extend and contract relative to the first housing 100 along the extending direction of the needle hole 101. In an embodiment, the sidewall of the first end 321 is provided with a limiting protrusion 3211, and in the step of inserting the second end 322 into the pinhole 101, the limiting protrusion 3211 is engaged with the inner surface 110, so that the stability is improved after the elastic thimble 320 is inserted into the pinhole 101, thereby facilitating the subsequent connection between the spring thimble 320 and the circuit board 310.

In step S830, the circuit board 310 is provided. Referring to fig. 9 and 10, the circuit board 310 is fixed to the first end 321 to electrically connect with the elastic spike 320. In an embodiment, the circuit board 310 is provided with a through hole 311, the circuit board 310 is attached to the position-limiting protrusion 3211, the first end 321 penetrates through the through hole 311, and then the solder 30 is used to solder the first end 321 to a side of the circuit board 310 away from the position-limiting protrusion 3211.

In step S840, the second housing 200 is provided. Referring to fig. 11, the second housing 200 is coupled to the inner surface 110 of the first housing 100 to form a receiving space, such that the resilient pins 320 and the circuit board 310 are received in the receiving space. It should be noted that, the second housing 200 and the first housing 100 may be connected by a threaded fastener, and in a process of mounting the second housing 200 to the first housing 100, that is, in a process of screwing the threaded fastener to connect the first housing 100 and the second housing 200, the circuit board 310 may gradually abut against an inner side of the second housing 200, so that the circuit board 310 is stably fixed in the accommodating space under the abutting of the second housing 200. Still alternatively, the circuit board 310 may be directly fixed to the inner surface 110 of the first housing 100 by a screw fastener or a jig before the second housing 200 is mounted. In addition, the second housing 200 is used for encapsulating the electronic component 300 mounted on the inner surface 110, and it is understood that in some embodiments, if the electronic component 300 is not encapsulated, the second housing 200 may be omitted, that is, the step S840 may be omitted.

According to the assembling method, the plurality of elastic thimbles 320 are independently installed in the needle hole 101, namely, the single elastic thimbles 320 are installed in the needle hole 101 in a one-to-one correspondence mode, namely, the installation among the plurality of elastic thimbles 320 is not influenced mutually, and the position accuracy of the assembling is ensured by the position accuracy of the needle hole 101, so that the independent installation of the elastic thimbles 320 can preferentially enable the precision processing of the needle hole 101 to be higher, the gap between the elastic thimbles 320 and the needle hole 101 is reduced, and the appearance is attractive. Compared with the prior art in which the elastic thimble is fixed to the circuit board first and then mounted, the clamping caused by the interference between the side wall of the elastic thimble 320 and the side wall of the pinhole 101 is not generated, and thus the phenomena of overlarge position stress of the pinhole 101 formed in the first shell 100, deformation of the rivet hole of the elastic thimble 320, and no rebound of the second end 322 of the elastic thimble 320 are caused.

In addition, for the structural design that the pinhole 101 has a trumpet-shaped opening, the trumpet-shaped structure of the pinhole 101 is favorable for the elastic thimble 320 to smoothly penetrate through the pinhole 101 from the inner surface 110 side, and the circumferential dimension of the second end 322 of the elastic thimble 320 can be designed to be equivalent to the size of the opening of the pinhole 101 on the outer surface 120 side (based on the trumpet-shaped opening design, the increase of the circumferential dimension of the second end 322 does not affect the smooth insertion of the elastic thimble 320 into the pinhole 101), so that the gap of the intersection line formed by the intersection of the second end 322 with the first wall surface 1011 and the outer surface 120 can be small enough after the second end 322 penetrates through the pinhole 101 and protrudes out of the outer surface 120, and the gap between the elastic thimble 320 and the pinhole 101 is in a small range, thereby ensuring the aesthetic property of the charging stand 20 on the outer surface 120 side. Even if the second end 322 abuts against the intersection line formed by the intersection of the first wall 1011 and the outer surface 120, the second end 322 is in line contact or point contact with the intersection line, and the frictional resistance between the two is small enough, so that the expansion and contraction of the second end 322 are not affected, and the charging reliability can be ensured after the conductive terminal 13 of the wearable device 10 is matched with the second end 322.
