Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The purpose of this invention is to provide a packaging structure for fixing and protecting sensors, in order to solve the problems existing in the prior art, and to protect the sensors and their connecting wires from external impacts and bumps, thus ensuring safety during transportation and use.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This utility model embodiment provides a packaging structure for fixing and protecting sensors, such as... Figure 1 and Figure 2 As shown, it includes a bobbin frame 1 and an outer packaging tube 2; wherein, the bobbin frame 1 has a long strip-shaped structure, and two snap-fit ​​parts are symmetrically arranged at one end of the bobbin frame 1 along the width direction; each of the two snap-fit ​​parts has a slot 11 at its opposite end, and the slots 11 of the two snap-fit ​​parts are used to snap-fit ​​with the printed circuit board. Figure 1 As shown, the two snap-fit ​​parts are integrally connected to the elongated main structure of the bobbin frame 1. Both slots 11 have openings on opposite sides and on the side furthest from the main structure. The two sides of the printed circuit board can be respectively fitted and inserted into the two slots 11 for installation and fixation. Figure 1 As shown, the direction parallel to the x-axis is the width direction of the bobbin skeleton 1, the direction parallel to the y-axis is the length direction of the bobbin skeleton 1, and the direction parallel to the z-axis is the thickness direction of the bobbin skeleton 1.

[0031] Furthermore, the bobbin frame 1 has wire support blocks near both ends along its length. These wire support blocks protrude from the two surfaces of the bobbin frame 1 along its thickness direction, and both end faces of the bobbin frame 1 are recessed inwards to form wire take-up grooves. For example... Figure 1 As shown, the wire support block is used to support the wire harness and includes a first wire support block 12 and a second wire support block 13, and the wire take-up groove is used to gather the wire harness and includes a first wire take-up groove 14 and a second wire take-up groove 15.

[0032] Furthermore, at least a portion of the bobbin 1 can be inserted into the outer packaging tube 2 for protection.

[0033] In some embodiments, the bobbin 1 has a first threading area 16 and a second threading area 17; the first threading area 16 and the second threading area 17 are spaced apart along the length direction of the bobbin 1, and both the first threading area 16 and the second threading area 17 penetrate the bobbin 1 along the thickness direction.

[0034] The present invention provides a label area 18 in the area before the first threading area 16 and the second threading area 17. The first threading area 16 and the second threading area 17 are hollowed out to contrast with the solid-filled label area 18. The first threading area 16 and the second threading area 17 are used to place the wire bundle, and the clamps of the automated winding device can clamp the spool frame 1, which facilitates flexible adjustment of the position of the sensor wire end after winding, and helps to save materials and reduce the overall weight of the packaging.

[0035] In some embodiments, two threading holes 19 are provided on the bobbin 1 near the snap-fit ​​portion, and the two threading holes 19 are symmetrically arranged on both sides of the corresponding take-up groove; and both threading holes 19 penetrate the bobbin 1 along the thickness direction. This utility model uses two threading holes 19 for threading wires.

[0036] In some embodiments, the two parts of the wire support block that protrude from the surface of the spool frame 1 along the thickness direction are provided with arc-shaped surfaces for contacting the wire harness; the take-up groove extends from the end face of the spool frame 1 to the end face of the wire support block, and the take-up groove penetrates the spool frame 1 along the thickness direction.

[0037] In this embodiment, the two wire support blocks have the same structure and are set to have a roughly semi-circular cross-section. The arc part contacts the wire harness. This technical solution facilitates the winding of the wire harness and protects the wires.

[0038] In some embodiments, the take-up groove has a V-shaped structure, and the opening width of one end of the take-up groove on the end face of the spool frame 1 is greater than the opening width of the other end of the take-up groove.

[0039] The take-up groove of this utility model is V-shaped, with one end located on the end face of the spool frame 1, and the width of the other end reduced to 0.5-3mm. This technical solution is adopted to facilitate the gathering of the wire bundle.

[0040] In some embodiments, such as Figure 2 As shown, the outer packaging tube 2 includes a tube body 21 and a flared portion 22; the tube body 21 has a cylindrical structure, the flared portion 22 has a trumpet-shaped structure, and one end of the tube body 21 is smoothly connected to the small diameter end of the flared portion 22; the inside of the tube body 21 is a skeleton placement area 23, and one end of the spool skeleton 1 can be inserted into the skeleton placement area 23 inside the tube body 21 from the large diameter end of the flared portion 22.

[0041] In some embodiments, the outer packaging tube 2 is made of a transparent material.

[0042] This utility model provides a flared portion 22 at one end of the transparent outer packaging tube 2. The flared portion 22 and the tube body 21 adopt an arc transition design. This technical solution facilitates packaging and helps protect the wire from accidental cutting and damage by the packaging. Furthermore, those skilled in the art can specifically choose the type of transparent material used for the outer packaging tube 2, and this utility model does not make specific limitations in this regard.

[0043] In some embodiments, both snap-fit ​​portions protrude from both sides of the bobbin frame 1 in the width direction, and both snap-fit ​​portions protrude from both surfaces of the bobbin frame 1 in the thickness direction.

[0044] The two slots 11 provided on the snap-fit ​​part of this utility model have a thickness of 1-5mm along the thickness direction. The cross-section of the slot 11 is roughly concave and has a wider width than other parts such as the main structure of the bobbin 1. This technical solution facilitates the placement and fixing of the sensor test printed circuit board, and facilitates the removal of the bobbin 1 from the transparent outer packaging tube.

[0045] In some embodiments, both snap-fit ​​parts of this invention are located on the outside of the outer packaging tube 2. This invention exposes the sensor's test printed circuit board by providing a printed circuit board slot 11 on the outside of the transparent outer packaging tube 2, thus facilitating sensor testing.

[0046] Example 2

[0047] This utility model embodiment provides a packaging structure for fixing and protecting sensors, such as... Figures 3 to 5 As shown, the difference between this embodiment and Embodiment 1 is that the first wire support block 12 in this embodiment is generally a cuboid structure. One end of the first wire support block 12 extends to the end face of one end of the spool frame 1, and the first take-up groove 14 extends from the end face of one end of the spool frame 1 to the interior of the first wire support block 12. The first take-up groove 14 penetrates the first wire support block 12 along the thickness direction.

[0048] And as Figure 3 As shown, in this embodiment, the two end faces of the first take-up groove 14 and the first wire support block 12 in the thickness direction are provided with a chamfered structure or a rounded corner structure. The chamfered structure or rounded corner structure is used to contact the wire, which facilitates the winding of the wire bundle and protects the wire.

[0049] It should be noted that the structure of the second wire support block 13 and the second wire take-up groove 15 in this embodiment is the same as that of the wire support block and the wire take-up groove in embodiment one; those skilled in the art can also set the two wire support blocks and the two wire take-up grooves to have the same structure as the first wire support block 12 and the first wire take-up groove 14 in embodiment two.

[0050] The spool frame 1 and transparent outer packaging tube 2 of this utility model facilitate sensor packaging and installation. The printed circuit board slot 11 is used to mount the sensor test printed circuit board; the first take-up slot 14 and the second take-up slot 15 are used to gather the wire bundle; the wire hole 19 is used for wire threading; the first wire support block 12 and the second wire support block 13 are used to support the wire bundle; the first wire threading area 16 and the second wire threading area 17 are used to place the wire bundle; and the label area 18 is used to place labels.

[0051] This invention protects the sensor and wires from external impacts and bumps by winding sensor wires around the linear shaft skeleton 1 and setting a transparent outer packaging tube 2 on the outside, thus ensuring safety during transportation and use.

[0052] Furthermore, by placing the snap-fit ​​part and the snap-fit ​​slot 11 on the outside of the outer packaging tube 2, the test printed circuit board connected to the sensor is exposed outside the transparent outer packaging tube 2. During the later factory and receiving tests, technicians can directly test without opening the packaging, which facilitates the detection of the sensor.

[0053] The packaging structure for fixing and protecting the sensor according to this utility model is used as follows:

[0054] When installing the sensor, the user inserts the sensor lead end into the threading hole 19 and holds the lead end in place by hand. Then, the user winds the lead around the spool frame 1, with the contact points between the lead and the spool frame 1 on the two sets of take-up grooves and the wire support blocks. After winding, the lead end is pulled out of the threading hole 19, and a test printed circuit board is soldered onto the lead end. The printed circuit board is then inserted into the printed circuit board slot 11. Finally, the spool frame 1 with the sensor installed is inserted into the transparent outer packaging tube 2.

[0055] When it is necessary to test the electrical parameters of the sensor, the user can directly connect the printed circuit board exposed outside the transparent outer packaging tube 2 into the measuring instrument to complete the test without removing the sensor.

[0056] When the sensor needs to be removed, the user pinches the outer edge of the printed circuit board slot 11 at the head of the spool frame 1 and pulls the spool frame 1 outward from the transparent outer packaging tube 2; then, the test printed circuit board is removed from the printed circuit board slot 11; finally, the sensor wires are unwound from the spool frame 1 one loop at a time.

[0057] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
