Description

Power adapter module

This case is about a power adapter module, especially a power adapter module that has a safe design to avoid arc carbon deposits, excessive temperature rise, and electric shock, and can provide waterproof and dustproof functions.

Power connection modules or power conversion modules have been widely used in various fields to transmit power from the power supply end to the power receiving end. For example, the power conversion module has been used to transmit power from charging stations or public electricity places to batteries installed in electric vehicles or hybrid vehicles. The power adapter modules used generally include industrial plugs and sockets to transmit power from the power source to the electrical equipment.

For users, the safety and reliability of the power connection module or power transfer module is very important. In other words, the power connection module or the power transfer module must be able to avoid the generation of leakage, which is very important. However, power connection modules and power conversion modules are often used in outdoor environments, and there is a great risk that some surrounding materials such as moisture or dust will enter the power connection modules or power conversion modules. . Once moisture or dust enters the power connection module or power adapter module, when the user connects the power connector or power adapter to the matched power connector or power adapter to transmit power, or When the self-assembled power connector or power adapter is disconnected and the power transmission is interrupted, the user is likely to suffer electric shock.

For example, when an electric vehicle needs to be charged from a charging station or a public electricity place, the user must use the charging adapter carefully. Charging adapters are usually used outdoors. Once moisture or dust enters the charging adapter, when the user connects the charging adapter to the matched connector or adapter to transmit power, or connects the charging adapter to the matched connector Or when the adapter is unplugged to interrupt the power transmission, you may suffer an electric shock. In order to prevent moisture or dust from entering the charging adapter when it is not in use, the charging adapter is generally equipped with a cover or cover to selectively cover or expose the electrical contacts, thereby achieving a considerable degree Waterproof and dustproof. However, this type of traditional technology has many shortcomings and inconveniences. When the charging adapter is not in use, the user is not accustomed to putting the cover or cover back on the opening of the charging adapter. In this case, the electrical contacts of the charging adapter are exposed to the surrounding environment, which is likely to cause the electrical contacts to corrode. Furthermore, the user may accidentally touch the electrical contacts of the charging adapter and suffer an electric shock. Also, when the user forgets to cover the cover or cover back to the opening of the charging adapter, and moisture or dust has entered the charging adapter, the user may connect the charging adapter to the corresponding assembly. When power is transmitted through the connector or adapter, or when the charging adapter is disconnected from the connector or adapter that is assembled to interrupt the power transmission, you will suffer an electric shock. In addition, the prior art technology fails to provide any safety structure to avoid accidental disconnection between the charging adapter and the mating connector or adapter during electrical connection.

In addition, these electric vehicles usually transmit large amounts of electricity during charging and power transmission. Therefore, during the process of plugging and unplugging the charging adapter, when the power is directly and instantaneously transmitted, it is easy to connect to the power terminal. Arc carbon deposits, excessive temperature rise, and instantaneous flashover may also occur. In the long run, the service life of the charging adapter will be reduced, and at the same time it will be more likely to cause problems such as use safety.

Therefore, it is necessary to provide an improved power adapter module to solve the aforementioned problems.

The purpose of this case is to provide a power adapter module that has a safe design to avoid arc carbon deposits, excessive temperature rise, and electric shock, and can provide waterproof and dustproof functions. The power adapter module includes a first power adapter group and a second power adapter group, and the first power adapter group is connected to the power supply end, and the second power adapter group is connected to the control module, When the first power adapter set and the second power adapter set are assembled correspondingly, the two buckling structures correspond to each other and are first axially butted to the first position, so that a plurality of first power terminals and a plurality of second power terminals are connected to each other.

The power terminal transmits power. This avoids the problems of arc carbon deposits and excessive temperature rise on the power terminals, and at the same time achieves the purpose of insulation and sealing protection. Furthermore, due to the corresponding design of the buckle structure, it is more labor-saving, time-saving and cost-saving when using the power adapter module.

FIGS. 4A to 4C are schematic diagrams showing the cross-sectional structure of the first power adapter group and the second power connector of the power adapter module of the first preferred embodiment of the present invention when they are assembled. Figures 5A to 5C show that the first buckling structure of the first power adapter set of the power adapter module and the second buckling structure of the second power connector of the first preferred embodiment of the present invention Schematic diagram of assembly operation. First, please refer to Figures 4A and 5A at the same time. As shown in the figure, when the first power supply unit 2 and the second power connector 3 are assembled correspondingly, the first housing 20 and the second housing 30-phase socket, as shown in Fig. 4A, the first casing 20 is sleeved outside the second casing 30, and the insulating casing 21 is sleeved inside the second casing 30. The positioning portion 21b of the housing 21 and the positioning groove 30b of the second housing 30 are mutually positioned, so that the insulating housing 21 can be conveniently sheathed in the second housing 30, and as described above, through the insulating housing 21 The protruding legs 21a and the guiding groove 30a of the second housing 30 are butted with each other, so that the insulating housing 21 and the second housing 30 can be assembled correspondingly. However, in the process of assembling, the first housing 20 is correspondingly sleeved outside the second housing 30, and through the first fastening structure 24 and the second housing 30 provided on the inner surface of the first housing 20 The second fastening structures 33 above correspond to each other. In this embodiment, as shown in FIG. 5A, the first fastening structure 24 can be, but not limited to, a triangular bump structure, and the second fastening structure 33 is an irregular groove structure. When assembling, the triangular bump structure of the first buckling structure 24 is moved and slid in the axial direction relative to the linear groove 33a of the second buckling structure 33 (as shown by the arrow in the figure). When it is set to the end of the linear groove 33a, it will interfere with an inclined surface 33b.

At the same time, it can be seen from Figure 4A that the plurality of second power terminals 31 in the second housing 30 pass through the plurality of through holes 211 on the insulating cover 210 of the insulating housing 21, and are connected with the plurality of through holes 211 in the first housing 20. The first power terminals 22 start to contact each other correspondingly. At this time, the first buckling structure 24 and the second buckling structure 33 are set in the first position, but at this time, the first power terminal 22 and the second power terminal 31 do not transmit power to each other. . In this embodiment, the first power terminal 22 and the second power terminal 31 can be, for example, female conductive terminals and male conductive terminals that are paired with each other, but are not limited to this. And, as shown in the figure, since the length of the second signal terminal 32 is shorter than that of the second power terminal 31, and the length of the first signal terminal 23 is also shorter than that of the first power terminal 22, when the first power terminal 22 and When the second power terminals 31 start to contact each other, the second signal terminal 32 has not passed through the plurality of through holes 211 on the insulating cover 210 of the insulating housing 21, so it has not yet contacted the first signal terminal 23. In this embodiment, the first signal terminal 23 and the second signal terminal 32 are also female and male conductive terminals that are paired with each other, but not limited to this.

Please continue to refer to Figures 4B and 5B. As shown in the figure, when the triangular bump structure of the first buckling structure 24 abuts the inclined surface 33b of the second buckling structure 33, the first buckling structure 24 And when the second buckle structure 33 is set in the first position, the user slightly applies stress to make the first housing 20 and the second housing 30 continue to be assembled in the radial direction, then the first buckle The triangular bump structure of the joint structure 24 will continue to slide along the inclined surface 33b to the top end of the inclined surface 33b, and due to the guidance of the inclined surface 33b, radial rotation between the first housing 20 and the second housing 30 is generated. As shown in Figure 5B, it can be seen that when the first buckling structure 24 is slid to the top of the inclined surface 33b of the second buckling structure 33, the first power terminal 22 and the second power terminal 31 are mutually But the first power terminal 22 and the second power terminal 31 still do not transmit power at this time. And, as shown in the figure, although the second signal terminal 32 has passed through the plurality of through holes 211 on the insulating cover 210 of the insulating housing 21, it has not yet contacted the first signal terminal 23.

As shown in Figures 4C and 5C, when the user applies stress to make the triangular bump structure of the first fastening structure 24 pass over the top end of the inclined surface 33b of the second fastening structure 33, the first fastening structure 24 The corresponding buckling is arranged in the fixing groove 33c of the second buckling structure 33, that is, the first buckling structure 24 and the second buckling structure 33 are correspondingly disposed at the second position. At this time, since the triangular bump structure of the first fastening structure 24 is pressed against the vertical surface 33d of the fastening groove 33c, it will be tightly fastened in the fastening groove 33c without displacement. With this actuation, the first housing 30 and the second housing 20 can be tightly buckled with each other to ensure a tight fitting relationship with each other. At the same time, as can be seen in Fig. 5C, at the same time as the tightly buckling, because of the simultaneous radial and axial movement, the first signal terminal 23 in the first housing 20 and the second housing 30 are The second signal terminals 32 are connected to each other correspondingly. When the first signal terminal 23 is connected to the second signal terminal 32, it will transmit an enabling signal to the control module 5. When the controller of the control module 5 receives the enabling signal, the controller then transmits a control signal to The power adapter module 1 controls the first power terminal 22 and the second power terminal 31 to start transmitting electric energy. It can be seen that through the design of the power adapter module 1 of this case, when the first housing 20 and the second housing 30 are not completely connected, that is, the first buckling structure 24 and the second buckling structure 33 are not completely connected. When set in the second position, there is no power transmission between the first power adapter group 2 and the second power adapter group 3, which can prevent the first power terminal 22 and the second power terminal 31 from contacting each other When the power is transferred, it is easy to cause carbon deposits in the arc, excessive temperature rise, and flashover due to the instantaneous excessive current. This can prolong the service life of the power adapter module 1 and prevent users from making mistakes. Electric shock and other situations caused by contact. In addition, the corresponding design of the first buckling structure 24 and the second buckling structure 33 in this case and the design of mutual displacement and engagement can be more labor-saving and energy-saving when the power adapter module 1 is used. Time and cost savings.

In summary, this case provides a power adapter module. The power adapter module includes a first power adapter group and a second power adapter group, and the first power adapter group includes a first housing, a plurality of first power terminals, and a plurality of first signal terminals , And the length of the plurality of first power terminals is greater than the plurality of first signal terminals; the second power adapter group includes a second housing, a plurality of second power terminals, a plurality of second signal terminals, and a plurality of first signal terminals The length of a power terminal is also greater than that of the plurality of first signal terminals. When the first power adapter set and the second power adapter set are assembled correspondingly, the first housing and the second housing are sleeved, so that the first buckling structure on the first housing and the second housing The second buckling structures above correspond to each other, and are first axially butted to the first position, so that the plurality of first power terminals are correspondingly connected with the plurality of second power terminals, but no electrical energy is transmitted, and then stress is applied to make the first A housing and a second housing are rotated correspondingly in a radial direction, so that the first buckling structure and the second buckling structure are correspondingly disposed at the second position, so that the first housing and the second housing are tightly buckled with each other, and The plurality of first signal terminals are correspondingly connected with the plurality of second signal terminals, and the enabling signal is transmitted to the control module. The control module further controls the plurality of first power terminals and the plurality of second power terminals to transmit electric energy. This design ensures that when the first power adapter set and the second power adapter set are closely matched to each other, the enable signal can be transmitted through the signal terminals contacting each other, and then the power terminals can be controlled to transmit electrical energy. Avoid problems such as arcing carbon deposits, excessive temperature rise, and flashover on the power terminals, thereby prolonging the service life of the power adapter module. In addition, an insulating shell can be provided on the first power adapter group to cover and protect the plurality of first power terminals and the plurality of first signal terminals, so as to achieve the purpose of insulation isolation and sealing protection. Therefore, the power adapter module in this case can not only avoid arcing carbon deposits, excessive temperature rise, flashover and electric shock, but also provide waterproof and dustproof functions and extend the service life of the power adapter module. Furthermore, due to the corresponding design of the buckle structure, it is more labor-saving, time-saving and cost-saving when using the power adapter module.

This case can be modified in many ways by those who are familiar with this technology, but it is not deviated from the protection of the scope of the patent application.
