[0050] A heater consists of a flat driver and a heat sink, with the driver connected to the radiator. Heaters come in either integrated or split versions. Integrated heaters have a direct, fixed connection between the driver and the heat sink, while split heaters have a direct electrical connection or some physical connection. The actual assembly relies on different mounting structures for each. The driver is provided with mounting holes for secure installation.

[0051] like Figure 1-3 The heater fixture shown in the figure includes a carrier plate assembly 1, a terminal assembly 2, and a plug assembly 3. Specifically, the carrier plate assembly 1 is provided with a first through-hole 111 for the heat sink to pass through, and is surrounded by several positioning pins 121 for positioning the driver. The terminal assembly 2 is mounted on the carrier plate assembly 1 and is used to connect to the interface on the driver. The plug assembly 3 is mounted on the carrier plate assembly 1 and is electrically connected to the terminal assembly 2 for connecting to an external test interface.

[0052] In the present invention, the heater is placed on the carrier plate group 1, and the heat sink extends downward through the first through hole 111. On the carrier plate group 1, as the radiator falls, the mounting hole on the driver is sleeved on the positioning pin 121. At this time, the carrier plate group 1 carries the driver and positions the driver; the terminal assembly 2 is connected to the interface on the driver, on the one hand to assist in fixing the driver, and on the other hand, to pre-connect the interface for subsequent power connection testing; the plug-in assembly 3 is fixed on the carrier plate group 1, and the terminal assembly 2 and the plug-in assembly 3 form a test adapter structure. The terminal assembly 2 is a structure for connecting to the driver, and the plug-in assembly 3 is a structure for external connection. Therefore, the plug-in assembly 3 connects to the external test interface, and the electrical signal is transferred to the driver through the terminal assembly 2. In this way, with the help of the present invention, the heater can be carried and the driver can be positioned, which facilitates precise automated assembly in subsequent processes. The interface is extended outward through the plug-in assembly 3 and the terminal assembly 2. During the transportation of the heater fixture, the convenience of external connection and testing is improved, which facilitates automated testing.

[0053] In some embodiments of the carrier plate assembly 1, such as Figure 2 、 Figure 4 As shown, the carrier board assembly 1 includes a motherboard 11 and a daughterboard 12 for supporting the driver. The motherboard 11 is provided with a first through-hole 111, and the daughterboard 12 is detachably mounted on the motherboard 11. The daughterboard 12 is provided with a second through-hole 122 for the heat sink to pass through, and a plurality of locating pins 121 are provided around the second through-hole 122 on the daughterboard 12. In this embodiment, the carrier board assembly 1 is configured as a motherboard 11 and a daughterboard 12, and the daughterboard 12 is detachable. In this way, when a different heater needs to be assembled, the unused daughterboard 12 can be replaced, so that the locating pins 121 on the daughterboard 12 are aligned with the corresponding heater, thereby improving the adaptability of the heater fixture to different heaters.

[0054] Specifically, the daughterboard 12 is provided with a roller-shaped ball buckle 123 for detachable connection with the motherboard 11. The motherboard 11 is provided with a male buckle 112 that mates with the roller-shaped ball buckle 123. When the daughterboard 12 is mounted on the motherboard 11, the male buckle 112 buckles into the roller-shaped ball buckle 123.

[0055] For the detachable connection between the daughter board 12 and the motherboard 11, it is also possible to provide undercuts on the motherboard 11 to fix the daughter board 12 to the motherboard 11. Alternatively, some hand screws are provided, which pass through the daughter board 12 and are connected to the motherboard 11, so that the daughter board 12 can be detachably mounted on the motherboard 11.

[0056] In some embodiments of the terminal assembly 2, such as Figure 4 、 Figure 5 As shown, the terminal assembly 2 includes a terminal mechanism 21 and a docking positioning assembly 22. The terminal mechanism 21 is arranged on the docking positioning assembly 22 and is used for docking with the driver for test. The terminal mechanism 21 is also connected to the plug assembly 3. The docking positioning assembly 22 is arranged on the carrier plate assembly 1, specifically on the motherboard 11, and is used to position the terminal mechanism 21. The terminal mechanism 21 is a docking structure. The docking positioning assembly 22 positions the terminal mechanism 21 when docking, preventing the terminal mechanism 21 from retreating or disengaging, and ensuring docking stability.

[0057] Of course, multiple terminal mechanisms 21 can be set on the terminal assembly 2, that is, multiple terminal mechanisms 21 are set on the docking assembly.

[0058] For the docking positioning component 22, specifically, Figure 4 、 Figure 5As shown, the docking positioning assembly 22 includes a terminal base plate 221, a guide rail 222, a first elastic member 223 and a positioning member 224. The guide rail 222 is arranged on the carrier plate group 1, specifically on the motherboard 11, and the arrangement direction of the guide rail 222 points to the first through hole 111. Preferably, the arrangement direction of the guide rail 222 is the same as the interface direction of the driver. The terminal base plate 221 is slidably arranged on the guide rail 222. The first elastic member 223 is connected to the terminal base plate 221 to pull the terminal base plate 221 away from the first through hole 111. The positioning member 224 is arranged on the terminal base plate 221. When the terminal base plate 221 slides to the terminal mechanism 21 to dock with the driver, the positioning member 224 positions the terminal base plate 221. The terminal mechanism 21 is arranged on the terminal base plate 221. The terminal base plate 221 is slidably disposed on the guide rail 222. The first elastic member 223 pulls the terminal base plate 221 away from the first through hole 111, that is, pulls the terminal base plate 221 away from the driver. In this way, when loading the heater, the docking positioning assembly 22 can pull the terminal mechanism 21 away from the driver to avoid interference or affecting the loading of the heater on the jig. After loading the heater, the terminal base plate 221 or the terminal mechanism 21 can be manually pushed so that the terminal mechanism 21 moves along the guide rail 222 toward the corresponding interface until the terminal mechanism 21 docks with the interface on the driver. At this time, the positioning member 224 positions the terminal base plate 221 so that the terminal mechanism 21 can maintain a stable docking with the interface of the driver.

[0059] When the terminal base plate 221 is elongated, it provides more space for arranging the terminal mechanisms 21. Thus, the terminal assembly 2 can be provided with multiple terminal mechanisms 21, each of which is disposed on the bottom of the terminal. The multiple terminal mechanisms 21 can be multiple high-voltage terminal mechanisms 21, multiple low-voltage terminal mechanisms 21, or at least one high-voltage terminal mechanism 21 and at least one low-voltage terminal mechanism 21.

[0060] In some specific embodiments of the positioning member 224, such as Figure 5 As shown, the middle portion of the positioning member 224 is hinged to the edge of the terminal base plate 221. The first end of the positioning member 224 extends outward from the terminal base plate 221. The second end of the positioning member 224 is provided with a second elastic member 225 that pushes the second end of the positioning member 224 upward, while the first end of the positioning member 224 is moved downward or pressed downward. The carrier plate assembly 1 is provided with a groove 113 for mounting the guide rail 222. The carrier plate assembly 1 is provided with a positioning hole 114 on one side of the groove 113. More specifically, the motherboard 11 is provided with a groove 113 for mounting the guide rail 222. The motherboard 11 is provided with a positioning hole 114 on one side of the groove 113. The positioning hole 114 is located on the sliding track of the first end of the positioning member 224.

[0061] When the terminal base plate 221 slides to the position where the terminal mechanism 21 docks with the driver, the first end of the positioning member 224 is locked into the positioning hole 114 .

[0062] In this embodiment, the middle portion of the positioning member 224 is hinged to the edge of the terminal base plate 221. The second end of the positioning member 224 is pushed by the second elastic member 225, and the first end of the positioning member 224 is in a real-time downward pressure state. After loading the heater, the terminal base plate 221 is manually pushed to move. When the first end of the positioning member 224 passes through the positioning hole 114, the first end of the positioning member 224 is locked into the positioning hole 114, and then the terminal base plate 221 is released. In this way, under the action of the first elastic member 223 and the second elastic member 225, the positioning member 224 is positioned at the positioning hole 114, or is locked at the positioning hole 114. The docking positioning assembly 22 is also positioned by the positioning member 224 and the positioning hole 114.

[0063] Of course, in order to improve the stability of the second elastic member 225, a receiving groove for accommodating the lower end of the second elastic member 225 is provided on the terminal base plate 221. In this way, the upper end of the second elastic member 225 is connected to the second end of the positioning member 224, and the lower end of the second elastic member 225 extends into the receiving groove, thereby maintaining the assembly stability of the lower end of the second elastic member 225 and preventing the second elastic member 225 from falling off.

[0064] In some embodiments of the terminal mechanism 21, such as Figure 5 As shown, the terminal mechanism 21 includes a docking terminal 211, a fixing block 212, and a buffer mechanism. The fixing block 212 is mounted on the docking positioning assembly 22, the buffer mechanism is mounted on the fixing block 212, and the docking terminal 211 is mounted on the buffer mechanism. The docking terminal 211 is connected to the fixing block 212 via the buffer mechanism, ensuring that the docking terminal 211 maintains pressure when docking with the driver, improving docking stability.

[0065] For buffer mechanisms, such as Figure 5 Specifically, it includes a connector 213, two guide rods 214, and two buffer springs 215. The fixed block 212 is provided with two guide holes arranged side by side, and the two guide rods 214 are slidably arranged in the guide holes. The connector 213 is arranged on one side of the fixed block 212 and connected to the two guide rods 214. The docking terminal 211 is arranged on the other side of the fixed block 212 and connected to the two guide rods 214. The two buffer springs 215 are respectively mounted on the two guide rods 214 and located between the fixed block 212 and the docking terminal 211.

[0066] Furthermore, the docking terminal 211 is a high-voltage terminal or a low-voltage terminal, that is, the docking terminal 211 in the aforementioned high-voltage terminal mechanism 21 is a high-voltage terminal, and the docking terminal 211 in the low-voltage terminal mechanism 21 is a low-voltage terminal.

[0067] Of course, the heater fixture can be provided with two sets of terminal assemblies 2, which are respectively located at the front and rear of the carrier board assembly 1, specifically at the front and rear of the motherboard 11, or at the front and rear sides of the first through hole 111. Heaters have many different shapes. For example, a driver may have all interfaces located on the front side, or interfaces may be provided on both the front and rear sides. Therefore, in some heater embodiments, two sets of terminal assemblies 2 may be provided.

[0068] In addition, guide bearings 4 are provided at the corners of the supporting plate group 1, that is, guide bearings 4 are provided at the corners of the motherboard 11. The guide bearings 4 can replace the motherboard 11 to contact the side of the conveying structure, reduce the resistance during contact, and improve the smoothness of the heater fixture transmission.

[0069] To facilitate sensing and statistics, in some embodiments, a sensing element 5 is provided on the carrier board group 1. Specifically, a sensing groove is provided at the bottom of the motherboard 11, and a sensing element 5 is provided in the sensing groove. The sensing element 5 can be an RFID sensing card.

[0070] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
