Both the trigger switch 3 and the drive component 1 are electrically connected to external controllers, etc., through the connector 5, avoiding direct electrical connection between the trigger switch 3 and the drive component 1 and the wiring harness. The connection operation between the connector 5 and the drive component 1 and the trigger switch 3 is simple, reducing the manufacturing cost of the portable electronic lock.

[0042] In one embodiment, such as Figure 4 and Figure 5 As shown, the insulating housing 51 is provided with a first terminal hole 511 and a second terminal hole 512. The driving terminal 52 is installed in the first terminal hole 511, and the trigger terminal 53 is installed in the second terminal hole 512. It can be understood that there are two of each of the first terminal hole 511 and the second terminal hole 512.

It can be understood that there are two drive conductive plates 6 and two trigger conductive plates 7. The two drive terminals 52 are connected to the positive and negative terminals of the drive component 1 respectively through the two drive conductive plates 6, and the two trigger terminals 53 are connected to the positive and negative terminals of the trigger switch 3 respectively through the two trigger conductive plates 7. The drive conductive plate 6 and the trigger conductive plate 7 are integrated on the lock housing 4 and located inside the lock housing 4.

[0044] Specifically, when the drive component 1 is installed in the internal space 41, the electrical terminal of the drive component 1 is directly inserted into the first slot 61 of the drive conductive plate 6, thereby the drive terminal 52 is electrically connected to the drive component 1 through the drive conductive plate 6; when the trigger switch 3 is installed in the internal space 41, the electrical terminal of the trigger switch 3 is directly inserted into the second slot 71 of the trigger conductive plate 7, thereby the trigger terminal 53 is electrically connected to the trigger switch 3 through the trigger conductive plate 7.

Preferably, the bottom wall of the internal space 41 is provided with a guide rib, and the lock seat 21 is provided with a guide groove. The guide rib is slidably inserted into the guide groove.

[0046] Specifically, the driving component 1 drives the gear 81 to rotate, and the gear 81 drives the lock seat 21 and the lock rod 22 to move through the rack 211. During the back-and-forth movement of the lock seat 21, the trigger switch 3 is triggered, and the back-and-forth movement of the lock rod 22 will lock or unlock with the external locking component 20. In this embodiment, the portable electronic lock has a simple structure and low manufacturing cost.

[0047] In one embodiment, such as Figure 2 and Figure 3 As shown, the lock box 4 includes a box body 44 and a box cover 45 that can be detachably covered on the box body 44.

[0050] The locking rod 22 is provided with an annular connecting groove 221, and the annular connecting protrusion 91 is inserted into the annular connecting groove 221. Understandably, the locking rod 22 is connected to the waterproof sleeve 9 through the annular connecting protrusion 91 inserted into the annular connecting groove 221. Thus, during the movement of the locking rod 22, the locking rod 22 will drive the waterproof sleeve 9 to extend and retract, and there is no gap between the waterproof sleeve 9 and the locking rod 22, further improving the waterproof rating of the portable electronic lock. In addition, the pressure plate 451 can press the annular flange 92 onto the first annular protrusion 441 from all directions, ensuring the stability of the waterproof sleeve 9 installed on the housing 44.

[0051] In one embodiment, such as Figure 1 and Figure 5 As shown, the outer wall of the box body 44 is provided with a first limiting hook 443 and a second limiting hook 444; when the box lid 45 is closed on the box body 44, the first limiting hook 443 and the second limiting hook 444 respectively engage with the opposite sides of the pressure plate 451.

In this embodiment, in the event of a power outage or damage to the drive component 1, the locking pin component 2 can be manually moved by adjusting the traction component 10. This portable electronic lock can be unlocked both electrically and manually.

[0055] In one embodiment, such as Figure 2 and Figure 7 As shown, the locking pin assembly 2 is provided with a receiving groove 23 and a fourth through hole 24 communicating with the receiving groove 23; the traction assembly 10 includes an elastic element 101 and a pull rod 102, one end of the pull rod 102 passing through the third through hole 46 and the fourth through hole 24 in sequence and extending into the receiving groove 23; it can be understood that the receiving groove 23 and the fourth through hole 24 are both provided on the lock seat 21, and the elastic element 101 includes, but is not limited to, a spring.

[0056] The pull rod 102 is provided with a limiting protrusion 1021 that slides into the receiving groove 23. The elastic element 101 is sleeved on the pull rod 102, and the opposite ends of the elastic element 101 abut against the limiting protrusion 1021 and the locking pin assembly 2, respectively. Understandably, the outer diameter of the limiting protrusion 1021 is larger than the outer diameter of the pull rod 102. Specifically, during the process of manually pulling the pull rod 102 and causing the locking pin assembly 2 to move backward, the pull rod 102 compresses the elastic element 101 through the limiting protrusion 1021. After releasing the pull rod 102, the rebound force of the elastic element 101 will cause the pull rod 102 and the locking pin assembly 2 to return to their original positions. Furthermore, during the process of the driving member 1 driving the locking pin assembly 2 forward, the locking pin assembly 2 will compress the elastic element 101, while the pull rod 102 remains stationary. In this embodiment, the traction assembly 10 has a simple structure and is easy to operate.

[0057] In one embodiment, such as Figure 3 and Figure 7 As shown, the traction assembly 10 also includes a pull rope 103 and a protective sleeve 104. The protective sleeve 104 is fitted onto the pull rod 102, and the pull rope 103 is connected to the end of the pull rod 102 away from the limiting protrusion 1021. Understandably, the pull rod 102 can move within the protective sleeve 104, so the protective sleeve 104 can protect the pull rod 102. The pull rope 103 is located outside the internal space 41 and the protective sleeve 104. The user pulls the pull rod 102 through the pull rope 103, which improves the convenience of the user pulling the pull rod 102.

[0058] The outer wall of the protective sleeve 104 is provided with a locking groove 1041. The portable electronic lock also includes a latch 20. The lock box 4 is also provided with a locking hole 47 communicating with the third through hole 46. The latch 20 is inserted into the locking hole 47 and the locking groove 1041, and is used to fix the protective sleeve 104 in the third through hole 46 through the locking groove 1041. Specifically, first, the protective sleeve 104 is inserted into the third through hole 46, and then the latch 20 is inserted into the locking hole 47. Since the latch 20 passes through the locking groove 1041 and abuts against the side wall of the locking groove 1041, the latch 20 can fix the protective sleeve 104 in the third through hole 46. After removing the latch 20 from the locking hole 47, the protective sleeve 104 can be removed from the third through hole 46. In this embodiment, the design of the latch 20 facilitates the assembly and disassembly of the protective sleeve 104 and the lock box 4.
