Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-9 A heating assembly includes a housing 2, an electric heating element 7, and a buffer pad 9. The electric heating element 7 includes a heating part 5 and a mounting part 6. The buffer pad 9 is limitedly assembled with the mounting part 6. The buffer pad 9 at least partially abuts against the housing 2 radially along the mounting part 6 and at least partially abuts against the housing 2 axially along the mounting part 6.

[0029] This device provides a buffer pad 9 between the mounting part 6 and the outer shell 2. The buffer pad 9 at least partially abuts against the outer shell 2 radially along the mounting part 6 and at least partially abuts against the outer shell 2 axially along the mounting part 6. Through radial and axial abutments, multi-directional elastic support is formed, which can effectively improve the shock resistance of the electric heating tube 7 after assembly. Since the electric heating tube has certain processing errors, there are certain assembly errors, such as uneven ends of the electric heating tube, spatial misalignment, and different fitting allowances between the electric heating tube and the outer shell. Using the buffer pad 9 as an intermediate connector between the electric heating tube 7 and the outer shell can improve the compatibility range between the electric heating tube 7 and the outer shell, increase the product qualification rate, and reduce the product scrap rate.

[0030] In one embodiment, the outer casing 2 includes a first casing 3 and a second casing 4, which are fixedly assembled. The heating part 5 is located in the first casing 3. The buffer pad 9 at least partially abuts against the second casing 4 radially along the mounting part 6, and / or the buffer pad 9 at least partially abuts against the second casing 4 axially along the mounting part 6.

[0031] The outer shell 2 of this device is composed of two parts: a first shell 3 and a second shell 4, which reduces the difficulty of assembly and molding. The first shell 3 protects the heating part 5, and the second shell 4 limits the buffer pad 9 axially and radially.

[0032] refer to Figure 3 , Figure 6 The second housing 4 has a first surface 12 and a second hole 13. The buffer pad 9 includes a ring 22. One end of the ring 22 has a flange 26 protruding outward. At least part of the outer periphery of the ring 22 abuts against the wall of the second hole 13. The flange 26 has a fourth surface 25 on the side near the ring 22. The fourth surface 25 abuts against the first surface 12. The second hole 13 provides radial elastic restraint to the ring 22, and the first surface 12 provides axial restraint to the flange 26, so that the mounting part 6 and the second housing 4 form a multi-directional elastic abutment.

[0033] In one embodiment, the ring body 22 includes a ring body portion 21. The ring body portion 21 has a plurality of spaced ribs 23 on its periphery. There is a gap 24 between adjacent ribs 23. The side of the rib 23 away from the ring body portion 21 abuts against the wall of the second hole 13. When the ribs 23 abut against the wall of the second hole 13, the ribs 23 are in an interference fit with the second hole 13. The rib-like characteristics can deform, reducing the compressive stress on the mounting portion 6.

[0034] As one implementation method, refer to Figure 7 , Figure 8The rib 23 is elongated, and multiple ribs 23 are arranged in a ring array around the periphery of the ring body 21; in one embodiment, the rib 23 is ring-shaped, and multiple ribs 23 are distributed at intervals along the axial direction of the ring body 21 (not shown in the figure).

[0035] As one assembly method of the buffer pad 9 and the mounting part 6, see reference Figure 6 The buffer pad 9 includes a ring 22 with a fourth hole 27. One end of the ring 22 has a flange 26 protruding outward. The end of the flange 26 away from the ring 22 has a fifth surface 28. The mounting part 6 includes a tube part 32 and a protrusion 11. The tube part 32 passes through the fourth hole 27 of the ring 22. The fifth surface 28 abuts against the protrusion 11. The mounting part 6 is provided with the protrusion 11. The fifth surface 28 abuts against the protrusion 11 to form an axial limiting abutment.

[0036] As one implementation method, refer to Figure 6 , Figure 7 The protrusion 11 has a non-circular cross-section along the radial section of the tube body 32. The first housing 3 has a first hole 10 that matches the shape of the protrusion 11. The mounting part 6 passes through the first hole 10, and the protrusion 11 is at least partially located in the first hole 10. The protrusion 11 is set as an irregular structure to prevent the heating tube 7 from rotating along the axial direction of the tube body 32.

[0037] In one embodiment, the outer shell 2 includes a first shell 3 and a second shell 4. The second shell 4 includes two half-shells 20. The half-shells 20 have a first edge 33 and a second edge 34. The first edge 33 has a second surface 16 and a first mounting hole 29 perpendicular to the second surface 16. The second edge 34 has a third surface 19, a second mounting hole 30 perpendicular to the third surface 19, and a second groove 18. The second surfaces 16 of the two half-shells 20 abut against each other and can be assembled through the first mounting hole 29. The buffer pad 9 is at least partially radially limited between the two second grooves 18 along the mounting portion 6. The third surface 19 abuts against the first shell 3 and can be assembled through the second mounting hole 30. The buffer pad 9 abuts against the third surface 19 at least partially along the axial direction of the mounting portion 6.

[0038] The second housing 4 of this device is formed by joining two half-shells 20 together. During assembly, the buffer pad 9 is fitted onto the mounting part 6, and the two half-shells 20 clamp the ring 22 of the buffer pad 9. It is fixed by screws or other components or by welding, and the third surface 19 of the bottom of the half-shell 20 abuts against the edge 26 of the buffer pad 9. This completes the assembly between the second housing 4, the buffer pad 9, and the mounting part 6. Then, the second edge 34 is abutted against the first housing 3 and fixed. The assembly is simple and convenient. The structure of the second housing 4 is relatively simple and easy to manufacture.

[0039] In one embodiment, the heating assembly is used in a semiconductor device. The heating assembly includes a connector 1, one end of which is assembled with a mounting portion 6, and the other end of which is connected to the semiconductor device. The housing 2 includes a first housing 3 and a second housing 4. The second housing 4 includes two half-shells 20, each half-shell 20 having a first groove 17 and a third groove 31. The connector 1 has a support portion 15, which is sandwiched between the two third grooves 31. The connector 1 is at least partially located between the two first grooves 17. The heating element 7 is connected to an external device via the connector 1, and because the connector 1 is assembled with the second housing 4, the overall structural integrity of the device is improved.

[0040] And / or the heating element 7 includes a tube base and an electrothermal film layer attached to the surface of the tube base. The tube base is a quartz tube, and the electrothermal film layer can be a nano-electrothermal film.

[0041] The connector 1 is a pillar connector, which can be understood as a type of connector used in semiconductor equipment; and / or the end of the mounting part 6 is located between the two first grooves 17, and there is a gap between the outer peripheral wall of the connector 1 and the wall of the first groove 17. The mounting part 6 is located away from the support part 15, and a gap is provided between the connector 1 and the wall of the first groove 17. When there is a large misalignment between the connector 1 and the mounting part 6, the gap serves as the deformation space of the connector 1, improving the adaptability of the heating tube 7 during assembly; and / or the second housing 4 is a plastic shell.

[0042] This device uses connector 1 as an intermediate connecting part between the second housing 4 and the mounting part 6. The second housing 4 bears the force applied by connector 1 to the mounting part 6 in a direction perpendicular to its axial direction, thereby reducing the probability of the heating element being broken.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
