AI Technical Summary
The cables of existing handheld devices are easily affected by external stress during use, which leads to a decrease in connection reliability and a non-compact structure.
A wire clamping mechanism is designed, including a plug receiving seat, a wire, and a PCB board. The wire has a plug and a fixing seat at both ends. The wire clamping part and the plug receiving seat form a wire clamping groove. The wire is fixed to the equipment housing by the fixing seat. The wire clamping part is engaged with the end of the wire. The plug can be stored in the receiving seat. The wire clamping part cooperates with the wire to restrict the movement of the end of the wire, thereby improving the strength and connection reliability.
It effectively protects the ends of the wires, improves the wires' strength and connection reliability, and makes the structure more compact and easier to store.

Abstract
Description
Technical Field
[0001] This utility model relates to a handheld device with an external cable, and more particularly to a cable securing mechanism and a handheld device. Background Technology
[0002] In some existing handheld devices, taking vehicle inspection equipment as an example, the operator needs to hold the main unit of the device and connect the wire to the vehicle's inspection interface during use. Since the wire is an outward-extending structure, it will inevitably be subjected to some external stresses, such as tensile forces, during use. These stresses will adversely affect the connection reliability of the wire core, thereby reducing the service life of the equipment. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a wire clamping mechanism and handheld device that has high strength, improves connection reliability, facilitates wire storage, and has a compact structure, in order to address the shortcomings of the existing technology.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.
[0005] A wire securing mechanism includes a plug receiver, a wire, and a PCB board. The plug receiver and the PCB board are both fixed inside the housing of a device. The two ends of the wire are respectively provided with a plug and a wire fixing seat. The plug is inserted into the plug receiver, and the wire fixing seat is fixedly connected to the housing of the device. The outer side wall of the plug receiver is provided with an outwardly protruding wire-locking part. A wire-locking groove is formed between the wire-locking part and the plug receiver. One end of the wire passing through the wire fixing seat is locked in the wire-locking groove, and the wire core led out from the end of the wire is electrically connected to the PCB board.
[0006] Preferably, the outer wall of the plug receiver and the outer wall of the wire clamp are both provided with lugs, which are fixedly connected to the housing of the device by screws.
[0007] Preferably, the wire clamping portion is L-shaped.
[0008] Preferably, the wire clamping portion is integrally formed with the plug receiving seat.
[0009] Preferably, the end of the wire core is connected to a pin header plug, which is engaged with a pin header socket on the PCB board.
[0010] A handheld device comprising the wire securing mechanism described above.
[0011] In the wire securing mechanism disclosed in this utility model, one end of the wire is fixedly connected to the housing of the device through the wire fixing seat, thereby fixing the wire to the housing. The free end of the wire is provided with the plug, which is used to plug into the target device. After the work is completed, the plug can be stored in the plug receiving seat, which can not only reasonably store the wire, but also improve the structural compactness. On this basis, based on the snap-fit cooperation between the wire clamping part and one end of the wire, the end of the wire can be effectively protected and restricted, avoiding the impact on the electrical connection reliability of the wire core due to the movement of the end of the wire. At the same time, it also makes the wire stronger and better meets the application requirements. Attached Figure Description

[0015] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.
[0016] This utility model discloses a wire securing mechanism, combined with Figures 1 to 3 As shown, it includes a plug holder 1, a wire 2, and a PCB board 3. The plug holder 1 and the PCB board 3 are both fixed inside the housing of a device. The two ends of the wire 2 are respectively provided with a plug 20 and a wire fixing seat 21. The plug 20 is inserted into the plug holder 1, and the wire fixing seat 21 is fixedly connected to the housing of the device. The outer side wall of the plug holder 1 is provided with an outwardly protruding wire-locking part 10. A wire-locking groove 11 is formed between the wire-locking part 10 and the plug holder 1. One end of the wire 2 passing through the wire fixing seat 21 is locked in the wire-locking groove 11, and the wire core 22 led out from the end of the wire 2 is electrically connected to the PCB board 3.
[0017] In the above structure, one end of the wire 2 is fixedly connected to the housing of the device through the wire fixing seat 21, thereby fixing the wire 2 to the housing. The free end of the wire 2 is provided with the plug 20, which is used to plug into the target device. After the work is completed, the plug 20 can be stored in the plug receiving seat 1, which can not only reasonably store the wire, but also improve the structural compactness. On this basis, based on the snap-fit cooperation between the wire clamping part 10 and one end of the wire 2, the end of the wire 2 can be effectively protected and restricted, avoiding the impact on the electrical connection reliability of the wire core 22 due to the movement of the end of the wire 2. At the same time, it also makes the wire stronger and better meets the application requirements.
[0018] As a preferred embodiment, both the outer wall of the plug receiver 1 and the outer wall of the cable clamping portion 10 are provided with lugs 12, which are fixedly connected to the device housing by screws. See also... Figure 2 The outer side wall of the plug receiving seat 1 and the outer side wall of the wire clamping part 10 can be provided with a total of three lugs 12. The three lugs 12 and the screws passing through the lugs can stably and reliably fix the plug receiving seat 1 into the housing of the device.
[0019] As a preferred embodiment, the locking wire portion 10 is L-shaped. See also... Figure 2 and Figure 3 In this embodiment, the wire-holding groove 11 should have a sufficient length, that is, the wire-holding portion 10 extends along the length direction of the outer side wall of the plug receiving seat 1. This wire-holding portion 10 with sufficient length can reliably restrict the wire 2, thereby preventing the end of the wire 2 from shifting.
[0020] To facilitate processing and molding, in this embodiment, the wire-clamping portion 10 and the plug receiving seat 1 are integrally formed. Preferably, the wire-clamping portion 10 and the plug receiving seat 1 are manufactured by injection molding.
[0021] Regarding the preferred connection method between the wire 2 and the PCB board 3, in this embodiment, the end of the wire core 22 is connected to a pin header plug 4, which is plugged into a pin header socket on the PCB board 3.
[0022] Based on the above structure, this utility model also proposes a handheld device, which includes the wire securing mechanism described above. In practical applications, this handheld device can be a handheld vehicle inspection device.
[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
