Description

Technical Field

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0032] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] like Figure 1-8 As shown, an embodiment of this utility model provides a temperature-controlled connector, adapted for connection with mating connector 2. It includes a housing 11, terminals 12 disposed within the housing 11, and a cable 13 with one end passing through the housing 11. The housing 11 also contains a temperature control mechanism, which includes a temperature control module for acquiring temperature information, a switch module, and a power supply module. The power supply module is electrically connected to and supplies power to the temperature control module and the switch module. The output end of the temperature control module is electrically connected to the control end of the switch module. The switch module is connected in series with one end of the terminal 12 and the cable 13. When the temperature information acquired by the temperature control module exceeds its internal preset threshold, the switch module cuts off the electrical transmission between the terminal 12 and one end of the cable 13. The specific connection relationship and principle between the modules are as follows: Figure 8 As shown.

[0036] The temperature control mechanism in this temperature-controlled connector includes a temperature control module, a switch module, and a power supply module. The temperature control module monitors the internal temperature of the connector and, when the temperature exceeds its preset threshold, cuts off the electrical transmission between terminal 12 and cable 13 through the switch module. Thus, this temperature-controlled connector can intelligently and autonomously monitor and control the internal temperature of the connector without relying on an external control system, effectively preventing malfunctions and dangers caused by excessive connector temperature from the source.

[0037] Considering the need to improve integration and reduce space occupation, such as Figure 3-7 As shown, in this embodiment, a circuit board 17 is provided inside the housing 11, the temperature control mechanism is integrated on the circuit board 17, and one end of the terminal 12 and the cable 13 are respectively connected to the circuit board 17 and connected in series with the switch module.

[0038] Specifically, the temperature control module, switch module, and power supply module are all integrated on the circuit board 17. The temperature control module includes a temperature sensor 16 and a control module electrically connected to the output of the temperature sensor 16. The output of the control module is electrically connected to the switch module. The control module of the temperature control module is an IC chip 161. The switch module includes an IGBT (Insulated Gate Bipolar Transistor) device. The power supply module includes a power supply circuit pre-printed on the circuit board 17. The temperature sensor 16 senses the temperature and transmits the temperature information to the IC chip 161. The IC chip 161 controls the IGBT device 15 to turn on or off according to a preset threshold, thereby realizing the on / off switching. The electrical transmission between terminal 12 and one end of cable 13 is interrupted. For example, when the temperature inside the housing 11 exceeds a preset threshold, IC chip 161 controls IGBT device 15 to cut off the electrical transmission between terminal 12 and cable 13. At this time, no heat is generated due to the interruption of electrical transmission, and the temperature inside the housing 11 gradually decreases. When the temperature drops below the preset threshold, IC chip 161 controls IGBT device 15 to reconnect the electrical transmission between terminal 12 and cable 13. Thus, this temperature-controlled connector can intelligently and autonomously monitor and control the internal temperature of the connector without relying on an external control system, effectively avoiding failures and dangers caused by excessive connector temperature from the source.

[0039] It should be noted that the temperature sensor 16, IC chip 161, IGBT device 15, and power supply circuit mentioned above are all conventional electrical technologies. Those skilled in the art are familiar with their specific working and control principles, conventional applications, and conventional equivalent replacement techniques. Furthermore, the innovation of this solution does not lie in the aforementioned devices and power supply circuits themselves. Therefore, the principles of the aforementioned devices and power supply circuits themselves and their more specific interconnections will not be elaborated upon.

[0040] In other embodiments besides this one, the devices and circuits included in the temperature control module, the switch module, and the power supply module can all be replaced by other conventional devices and circuits that can achieve the same function. For example, the IGBT device of the switch module can be replaced by a suitable relay.

[0041] Furthermore, in order to achieve a reliable connection between one end of terminal 12 and circuit board 17 and to facilitate electrical connection with the switch module, such as Figure 4-6 As shown, in this embodiment, one end of the terminal 12 is provided with a plurality of first pin portions 121. The first pin portions 121 can be integrally formed with the terminal 12. The circuit board 17 is provided with a plurality of first sockets. The plurality of first pin portions 121 are inserted into the corresponding first sockets and electrically connected to the switch module. More specifically, the first pin portions 121 make conductive contact with the copper sheet circuit or copper layer circuit that is pre-set in the first socket and connected to the switch module. Then, the first pin portions 121 can be fixed in the first socket by soldering.

[0042] Furthermore, in order to achieve a detachable connection between one end of cable 13 and circuit board 17 and to facilitate electrical connection with the switch module, such as Figure 4-7 As shown, in this embodiment, one end of the cable 13 is provided with a conductive pad 131. The conductive pad 131 has several second pin portions 132 on its end face facing the circuit board 17. The circuit board 17 has several second sockets. The several second pin portions 132 are inserted into corresponding second sockets and electrically connected to the switch module. The conductive pad 131 and the circuit board 17 are fixed together by bolts, so that one end of the cable 13 is electrically connected to the switch module through the conductive pad 131 and the second pin portions 132, and this facilitates the installation and removal of one end of the cable 13. The specific connection and conductivity method between the second pin portion 132 and the second socket refers to the connection and conductivity method between the first pin portion 121 and the first socket.

[0043] Furthermore, in order to make the connector of this embodiment compatible with aluminum cables 13, such as Figure 4-7 As shown, in this embodiment, one end of the cable 13 is welded and fixed to the conductive pad 131. A bolt 134 is threaded through the conductive pad 131 and passes through the circuit board 17 before connecting to a pre-placed nut 133, thereby achieving a bolted connection and fixation between the conductive pad 131 and the circuit board 17. In this embodiment, the second pin portion 132 and the second socket are distributed around the nut 133. The conductive pad 131 and the second pin portion 132 can be integrally made of copper / copper alloy.

[0044] Furthermore, in order to obtain electrical energy from external sources, such as Figure 2 and Figure 4-7 As shown, in this embodiment, the power supply module is adapted to connect with a number of mating power supply terminals 14 in the housing 11 and a number of mating power supply terminals in the mating connector 2. The power supply terminals 14 are pin terminals that can be embedded in the core. The core includes an upper core 112 and a lower core 113 that are interlocked. The power supply terminals 14 can be embedded in the lower core 113. In addition, one end of the power supply terminal 14 is plugged into the mating power supply terminal and the other end is electrically connected to the circuit board 17. The electrical connection between the other end of the power supply terminal 14 and the circuit board 17 can refer to the connection method between the first pin part 121 or the second pin part 132 and the first socket or the second socket, which will not be described in detail here.

[0045] Furthermore, considering that the temperature control mechanism, especially the switching module, may generate heat during operation and accumulate inside the housing 11, affecting the normal operation of the temperature control module, such as... Figure 1-2As shown in this embodiment, a heat dissipation port is provided on the housing 11 at the position corresponding to the temperature control mechanism. A heat dissipation plate 3 with a closed heat dissipation port is installed on the housing 11. The heat dissipation plate 3 has better thermal conductivity than the housing 11. Heat can be discharged from the heat dissipation plate 3 more quickly, so that both the heat generated by the temperature control mechanism and the heat generated by the electrical energy transmission inside the housing 11 can be discharged.

[0046] In this embodiment, the housing 11 is made of plastic, the heat sink 3 is made of aluminum / aluminum alloy, and a number of heat sink ribs 31 are provided on the outer side of the heat sink 3 to increase the heat dissipation area and strengthen the structural strength.

[0047] like Figure 1 As shown, the embodiment of this utility model also provides a connection component, including a connector, a mating connector 2 and an external power supply system 4. The connector is a temperature-controlled connector as described above. The power supply module is adapted to the mating power supply terminal in the mating connector 2 through the power supply terminal 14 disposed in the housing 11. The mating power supply terminal is electrically connected to the external power supply system 4.

[0048] The aforementioned mating power supply terminal 14 can refer to conventional adapter terminals that can mate with pins. The mating power supply terminal is electrically connected to the external power supply system 4 through wires. Furthermore, the structure and assembly of the above adapter terminals and wires can be implemented by conventional structures and techniques known to those skilled in the art, so they will not be described in detail or shown in the figures here.

[0049] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
