[0028] like Figures 1 to 7 As shown, a potting mold for bottom-centering NTC packaging is used to package the bottom-centering NTC into a housing 2. The potting mold includes a positioning mold 3, an adjustment component 4, a fixing component and a positioning docking component 6; the positioning mold 3 is provided with a positioning groove 301 for placing the NTC1, and the head of the NTC1 extends out of the positioning mold 3; the adjustment component 4 is used to adjust the extension length of the NTC1 head in the positioning mold 3 to adapt to the depth of the housing 2; the fixing component is used to fix the NTC1 in the positioning groove 301; the positioning docking component 6 is provided with a positioning hole 601 for placing the housing 2; the positioning docking component 6 is used to position and dock with the positioning mold 3 so that the head of the NTC1 touches the bottom and is inserted into the housing 2.

[0029] As an example, the potting mold for a bottom-centered NTC package according to an embodiment of the present application is used to package an NTC in a bottom-centered manner within a housing 2. The potting mold includes a positioning mold 3, an adjustment component 4, a fixing component, and a positioning and docking component 6. Specifically, the positioning mold 3 defines a positioning groove 301 for receiving an NTC 1. The pin ends of the NTC 1 are placed in the positioning groove 301, with the NTC 1 head extending beyond the positioning mold 3 to facilitate insertion of the NTC 1 head into the housing 2 in subsequent steps. The adjustment component 4 is used to adjust the extension length of the NTC 1 head within the positioning mold 3 to accommodate the depth of the housing 2, ensuring that the NTC 1 head contacts the bottom of the housing 2 when packaged within the housing 2. After the extension length of the NTC 1 head is adjusted, the fixing component secures the NTC 1 in the positioning groove 301 to prevent it from shifting. This ensures that the NTC 1 maintains precise positioning and docking with the housing 2 during the docking process between the positioning mold 3 and the positioning and docking component 6. After the NTC1 on the positioning mold 3 is adjusted and fixed, the positioning mold 3 is transferred to the positioning docking assembly 6 for positioning docking. The positioning docking assembly 6 is provided with a positioning hole 601 for placing the housing 2. The position of the positioning hole 601 is set corresponding to the position of the positioning groove 301 on the positioning mold 3. The positioning hole 601 and the positioning groove 301 are respectively used to accurately position the housing 2 and the NTC1, thereby ensuring that when the NTC1 is encapsulated in the housing 2, the NTC1 head can be inserted centrally into the housing 2. Therefore, when the positioning docking assembly 6 and the positioning mold 3 are positioned and docked, the NTC1 head can be inserted into the housing 2 with the bottom touching the center.

[0030] At the same time, in order to improve the packaging efficiency, a plurality of positioning grooves 301 are arranged in parallel on the positioning mold 3, and a plurality of positioning holes 601 are also correspondingly provided on the positioning docking component 6. A single positioning docking process of the positioning mold 3 and the positioning docking component 6 can realize the bottom-contacting and centered packaging of multiple groups of NTC1 and the shell 2.

[0031] The potting mold for bottoming and centering the NTC package provided in this embodiment ensures that the NTC can accurately touch the bottom and be inserted into the center of the shell during the packaging process by accurately positioning the NTC and the shell and adjusting the protruding length of the NTC head. This achieves precise docking between the NTC and the shell, ensures the stability of the NTC during the packaging process, improves the packaging quality and efficiency, and has the advantages of simple structure and easy operation. It can be widely used in the packaging process of NTC.

[0032] In one embodiment, the adjustment assembly 4 includes a base 41 and a limit member 42. The base 41 is provided with a fixing groove 411 for placing the positioning mold 3; the limit member 42 is slidably connected to the base 41 to adjust the distance from the limit member 42 to the positioning mold 3; when the positioning mold 3 is placed in the fixing groove 411, the head of the NTC1 contacts the limit member 42.

[0033] As an example, the adjustment assembly 4 of this embodiment includes a base 41 and a stopper 42. The base 41 is provided with a fixing groove 411, into which the positioning mold 3 is placed for fixation. Furthermore, the base 41 is provided with a receiving groove for the NTC head, which corresponds one-to-one with the positioning groove 301 on the positioning mold 3. The stopper 42 is positioned on one side of the fixing groove 411 and is slidably connected to the base 41, allowing the distance between the stopper 42 and the positioning mold 3 to be adjusted according to the depth of the housing 2. After the position of the stopper 42 is adjusted, the positioning mold 3 is placed in the fixing groove 411, with the NTC head facing one side of the stopper 42. The NTC head is then moved so that it contacts the stopper 42. Since the distance between the stopper 42 and the positioning mold 3 matches the depth of the housing 2, the length of the NTC head extending outside the positioning mold 3 also matches the depth of the housing 2. This ensures that when the NTC head is encapsulated in the housing 2, it can contact the bottom of the housing 2.

[0034] In one embodiment, the adjustment assembly 4 also includes a slider 43 and an elastic member 44; a slide groove 412 is provided on the base 41, the slider 43 is slidably connected in the slide groove 412, and the elastic member 44 is connected to the slider 43 and the base 41. The pre-tightening force of the elastic member 44 drives the slider 43 to contact the positioning mold 3 to fix the positioning mold 3 in the fixing groove 411.

[0035] As an example, see Figures 1 to 3 In order to facilitate the removal and placement of the positioning mold 3 from the base 41, the width of the fixing groove 411 of this embodiment is greater than the width of the positioning mold 3. At the same time, in order to fix the positioning mold 3 in the fixing groove 411, the adjustment component 4 is further provided with a slider 43 and an elastic member 44. By providing a slide groove 412 on the base 41, the slider 43 is slidably connected to the slide groove 412, and the elastic member 44 is connected to the slider 43 and the base 41. When the positioning mold 3 is placed in the fixing groove 411, the pre-tightening force of the elastic member 44 drives the slider 43 to contact the positioning mold 3, thereby fixing the positioning mold 3 in the fixing groove 411. When the positioning mold 3 needs to be removed, the positioning mold 3 is pushed to one side of the slider 43 to press it tightly, or the slider 43 is directly pushed to slide the slider 43 into the slide groove 412 to unlock it, and then the positioning mold 3 can be quickly removed.

[0036] In one embodiment, a guide post 413 is provided on the base 41 , a guide slot 421 is defined on the limiting member 42 , and the guide post 413 is slidably connected to the guide slot 421 .

[0037] As an example, see Figure 1 and Figure 2To further improve the accuracy and stability of adjustment, a guide post 413 is provided on the base 41, and a guide groove 421 is provided on the limiter 42. The guide post 413 is slidably connected to the guide groove 421. In this way, the limiter 42 can maintain a stable motion trajectory during the sliding process and slide smoothly during the adjustment process.

[0038] In one embodiment, the fixing assembly includes a magnetic member 51 and an attachment member; the magnetic member 51 is provided in the base 41 for magnetically fixing the head of the NTC 1 ; the attachment member is used to attach and fix the NTC 1 to the positioning mold 3 .

[0039] As an example, see Figure 3 After the extension length of the NTC1 head is adjusted, in order to keep the NTC1 in a fixed position on the positioning mold 3; the fixing component of this embodiment includes a magnetic component 51 and an attachment. The magnetic component 51 is set in the base 41. The magnetic attraction of the magnetic component 51 fixes the NTC1 head to prevent the NTC1 from moving easily; then the attachment is used to attach and fix the NTC1 to the positioning mold 3, thereby ensuring that the NTC1 is stably fixed on the positioning mold 3 and will not move or fall off during the packaging process.

[0040] In one embodiment, the positioning docking assembly 6 includes a base 61 and a locking assembly 62. The base 61 is provided with a positioning hole 601 and a positioning column 611. The positioning mold 3 is provided with a docking hole 302. The positioning column 611 is plugged into the docking hole 302. The locking assembly 62 is used to lock the positioning mold 3 on the base 61.

[0041] As an example, see Figures 4 to 7 The positioning and docking assembly 6 of this embodiment includes a base 61 and a locking assembly 62. A positioning hole 601 is provided on the base 61, and positioning posts 611 are provided on both sides of the base 61. Docking holes 302 are provided at both ends of the positioning mold 3. The positioning posts 611 and the docking holes 302 are plugged in and matched one by one to achieve precise positioning and docking of the base 61 and the positioning mold 3, so that the NTC1 in the positioning groove 301 is centered and aligned with the housing 2 in the positioning hole 601. The locking assembly 62 is used to lock the positioning mold 3 on the base 61 to ensure that the positioning mold 3 does not move during the potting process. At the same time, in order to improve the packaging efficiency, two groups of positioning posts 611 are provided in parallel on the base 61, and two groups of positioning grooves 301 are also provided accordingly, so that the base 61 can be positioned and docked with two groups of positioning molds 3 at the same time.

[0042] In one embodiment, the locking assembly 62 includes a screw 621, a clamping member 622 and a nut 623; the screw 621 is fixedly connected to the base 61, and the clamping member 622 is provided with a through hole, and the screw 621 is passed through the through hole; the clamping member 622 is pressed onto the top of the positioning mold 3, and is screwed to the screw 621 through the nut 623 to lock the clamping member 622 and the positioning mold 3 on the base 61.

[0043] As an example, see Figures 5 to 7 The locking assembly 62 of this embodiment includes a screw 621, a pressing member 622, and a nut 623. The screw 621 is fixedly connected to the base 61, and the pressing member 622 is provided with a through hole.
