[0047] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0048] like Figures 1 to 3 As shown, Figures 1 to 3 It is shown that the present application provides a novel connector with a TPA structure. A novel connector with a TPA structure provided by an embodiment of the present application includes a plug housing 1 with an opening at one end and a socket housing 2 with an opening at one end. Among them, a plug assembly 10 is fixedly arranged in the plug housing 1, and a socket assembly 20 is fixedly arranged in the socket housing 2. The open end of the plug housing 1 and the open end of the socket housing 2 are plugged into each other. When the two are plugged into each other, the plug assembly 10 and the socket assembly 20 are also plugged into each other to achieve circuit conduction and signal conduction.

[0049] In one embodiment, the plug housing 1 and the socket housing 2 are connected to each other by snapping. Figure 4 As shown, the plug housing 1 can also be movably provided with a locking piece 3. When the plug housing 1 and the socket housing 2 are plugged into each other, one end of the locking piece 3 can also clamp the socket housing 2, thereby further ensuring that the plug housing 1 and the socket housing 2 can be firmly connected to avoid accidental falling off. Figure 4 The plug assembly 10 includes a plug mounting seat 100 and a socket terminal 101, wherein the socket terminal 101 is disposed in the plug mounting seat 100. Figure 5The socket assembly 20 includes a socket mounting seat 200 and a plug-in terminal 201 . The plug-in terminal 201 is arranged in the socket mounting seat 200 . The plug-in terminal 201 and the slot terminal 101 are plugged into each other to achieve circuit conduction between the plug assembly 10 and the socket assembly 20 .

[0050] Specifically, see Figure 4 and Figure 5 In the embodiment shown in the figure, there are two slot terminals 101 and two plug-in terminals 102, one of which is plugged into one of the plug-in terminals 102, and the two correspond to the positive line, and the other slot terminal 101 is plugged into the other plug-in terminal 102, and the two correspond to the negative line.

[0051] Furthermore, as described in the background technology, the high-voltage connectors of new energy vehicles currently make it difficult to identify whether the signal terminals and power terminals are assembled in the correct position when assembling the wiring harness. If they are not assembled in the correct position, it will cause connection failure, affect product quality, and even cause vehicle accidents.

[0052] Therefore, to solve the above problems, see Figures 4 to 7 The embodiment of the present application provides a novel connector with a TPA structure, which further includes a locking assembly 30. The locking assembly 30 is clamped on the plug mounting seat 100 and the socket mounting seat 200, and abuts against the slot terminal 101 and the plug terminal 201 at the same time, so as to limit the displacement of the slot terminal 101 relative to the plug terminal 201, and the displacement of the plug terminal 201 relative to the slot terminal 101. That is, the locking assembly 30 is used to prevent the plug terminal 201 and the slot terminal 101 from loosening when they are plugged into each other, thereby ensuring the connection reliability of the novel connector with a TPA structure.

[0053] Furthermore, the locking assembly 30 includes a plug locking member 31 and a socket locking member 32. Figure 4 and Figure 6 As shown, the plug locking member 31 is clamped on the plug mounting seat 100 and abuts against the slot terminal 101 to limit the displacement of the slot terminal 101 relative to the plug terminal 201. Figure 5 and Figure 7 As shown, the socket locking member 32 is clamped on the socket mounting seat 200 and abuts against the plug terminal 201 at the same time, limiting the displacement of the plug terminal 201 relative to the slot terminal 101.

[0054] It is understandable that the locking assembly 30 may also include only the plug locking member 31 or only the socket locking member 32, and there is no special limitation here. When only the plug locking member 31 is included, the displacement of the slot terminal 101 relative to the blade terminal 201 is limited by the plug locking member 31, and when only the socket locking member 32 is included, the displacement of the blade terminal 201 relative to the slot terminal 101 is limited by the socket locking member 32. Obviously, the locking assembly 30 includes both the plug locking member 31 and the socket locking member 32, which enables the locking assembly 30 to abut against the slot terminal 101 and the blade terminal 102 in two opposite directions, respectively, to ensure that the slot terminal 101 and the blade terminal 102 are tightly plugged into each other, and has the best technical effect.

[0055] Specifically, Figure 4 As shown, the slot terminal 101 is provided with a slot 1011. Figure 5 As shown, the plug terminal 201 includes a plug connection block 2011 and a plug 2012 connected to the plug connection block 2011, the plug 2012 is plugged into the slot 1011 of the slot terminal 101, the plug locking member 31 abuts against one end of the slot terminal 101 away from the plug terminal 201, and the socket locking member 32 abuts against one end of the plug connection block 2011 of the plug terminal 201 away from the slot terminal 101.

[0056] More specifically, in one embodiment, Figures 8 to 10 As shown, the plug locking member 31 includes a plug mounting ring 311 and a plug locking piece 312. The plug locking piece 312 is connected to the inner circumference of the plug mounting ring 311. The plug mounting seat 100 is provided with a plug mounting groove 1001 that connects the inside and the outside of the plug mounting seat 100. The plug mounting ring 311 is sleeved on the plug mounting seat 100. The plug locking piece 312 can be optionally in an inverted T shape, which passes through the plug mounting groove 1001 and extends into the plug mounting seat 100 to abut against the slot terminal 101, increase the contact force between the slot terminal 101 and the plug terminal 201, and prevent the slot terminal 101 from being displaced relative to the plug terminal 201 during use. In this embodiment, since there are two slot terminals 101, accordingly, there are also two plug locking pieces 312, and each plug locking piece 312 abuts against a corresponding slot terminal 101.

[0057] In the structure of the socket locking member 32, as shown in FIG. Figure 8 , Fig. 9 and Fig.11As shown, similar to the structure of the plug locking member 31, the socket locking member 32 includes a socket mounting ring 321 and a socket locking piece 322, the socket locking piece 322 is connected to the inner circumference of the socket mounting ring 321, the socket mounting seat 200 is provided with a socket mounting groove 2001 connecting the inside and the outside of the socket, the socket mounting ring 321 is sleeved on the socket mounting seat 200, and the socket locking piece 322 passes through the socket mounting groove 2001 and extends into the socket mounting seat 200 to abut against the plug connection block 2011 of the plug terminal 201, increase the contact force between the plug terminal 201 and the slot terminal 101, and prevent the plug terminal 201 from being displaced relative to the slot terminal 101 during use. In this embodiment, since there are also two plug terminals 201, accordingly, there are also two socket locking pieces 322, each of which abuts against the plug connection block 2011 of a corresponding plug terminal 201.

[0058] In this way, when the docking connector is assembled, if the slot terminal 101 is not properly plugged into the blade terminal 201, the plug locking member 31 cannot be snapped onto the plug mounting seat 100, or if the blade terminal 201 is not properly plugged into the slot terminal 101, the socket locking member 32 cannot be snapped onto the socket mounting seat 200, so that the user can immediately identify whether the slot terminal 101 and the blade terminal 201 are properly assembled by observing whether the plug locking member 31 is snapped onto the plug mounting seat 100 and whether the socket locking member 32 is snapped onto the socket mounting seat 200, thereby facilitating the user's operation and making the connection between the plug assembly 10 and the socket assembly 20 more reliable.

[0059] Furthermore, in order to make the plug mounting seat 100 and the socket mounting seat 200 more reliably connected without shaking, as shown in FIG. Fig.12 As shown, the plug mounting seat 100 has a first plug post 1002, the first plug post 1002 has a receiving cavity 1003, and the socket terminal 101 is disposed in the receiving cavity 1003; Fig.13 As shown, a first plug-in slot 2002 is opened at one end of the socket mounting base 200, the plug-in terminal 201 is arranged in the first plug-in slot 2002, and one end of the first plug-in column 1002 is inserted into the first plug-in slot 2002, so that one end of the plug-in 2012 extends into the accommodating cavity 1003 and is inserted into the slot 1011.

[0060] Preferably, one end of the first plug post 1002 is provided with a plug hole 1004 connected to the accommodating cavity 1003, and the plug piece 2012 is inserted into the plug hole 1004; and / or the first plug slot 2002 has a first spacer 2003, and the first spacer 2003 is provided with first through holes 2004 penetrating two opposite sides thereof, and the plug piece 2012 is inserted into the first through hole 2004. Fig.12 and Fig.13 In the embodiment shown in , the plug hole 1004 and the first through hole 2004 are both rectangular, matching the cross-sectional shape of the plug piece 2012, and the sizes of the plug hole 1004 and the first through hole 2004 are slightly larger than the cross-sectional size of the plug piece 2012. Thus, when the plug piece 2012 is sequentially inserted into the plug hole 1004 and the first through hole 2004, the plug piece 2012 can be well positioned, thereby preventing the plug piece 2012 from being deformed due to force when being plugged into the slot terminal 201.

[0061] It should be noted that since there are two slot terminals 101 and two plug-in terminals 201 respectively, it is not difficult to understand that there are also two first plug-in posts 1002 and two first plug-in slots 2002 respectively, which will not be described in detail here.

[0062] In one embodiment, in order to ensure signal conduction between the plug assembly 10 and the socket assembly 20, refer to Figure 4 The plug mounting base 100 is also provided with a signal plug 103, one end of which has a plug-in portion 1031, see Figure 5 The socket mounting seat 200 is also provided with a signal terminal 104, and the signal terminal 104 has a signal slot 1041, and the plug-in portion 1031 is plugged into the signal slot 1041. Figure 4 and Figure 5 As shown, in the embodiment shown in the figure, the signal plug 103 has two plug-in parts 1031, and the signal terminal 104 also has two corresponding ones. Fig.14 As shown, each plug-in portion 1031 is plugged into a corresponding signal slot 1041 of a signal terminal 104 .

[0063] Specifically, please continue to refer to 14, each signal terminal 104 has two oppositely arranged spring pieces 1042, the two oppositely arranged spring pieces 1042 form a signal slot 1041, and the spring pieces 1042 are configured to be able to undergo a recoverable deformation when the plug-in portion 1031 is connected to the signal slot 1041, so as to clamp the plug-in portion 1031 in the signal slot 1041. In this way, through the above configuration, it can be ensured that the plug-in portion 1031 is reliably plugged into the signal slot 1041, so as to improve the reliability and stability of signal conduction.

[0064] Furthermore, in this embodiment, the plug mounting seat 100 also has a second plug-in column 1005 interconnected with the signal plug 103, and the plug-in portion 1031 of the signal plug 103 is exposed on the second plug-in column 1005. A second plug-in slot 2005 is opened at one end of the socket mounting seat 100, and the signal terminal 104 is arranged in the second plug-in slot 2005. One end of the second plug-in column 1005 is inserted into the second plug-in slot 2005, so that the plug-in portion 1031 is accommodated in the second plug-in slot 2005 and plugged into the signal slot 1041.

[0065] Similarly, in order to prevent the plug-in portion 1031 from being deformed due to the large force when it is plugged into the signal slot 1041, a second spacer 2006 is provided in the second plug-in slot 2005. The second spacer 2006 also has a second through hole 2007 running through the opposite sides of itself. The shape of the second through hole 2007 matches the shape of the cross section of the signal plug 102, and the size is slightly larger than the cross-sectional size of the signal plug 102, so as to achieve the purpose of limiting the signal plug 102 to prevent the signal plug 102 from deforming.

[0066] In addition, to facilitate the disassembly and assembly of the docking connector, please refer to Figure 4 and Figure 5 The end of the plug housing 1 away from the socket housing 2, and the end of the socket housing 2 away from the plug housing 1 are also detachably provided with a first tail cover 4 and a second tail cover 5. In order to ensure installation sealing, the first tail cover 4 is connected to the plug housing 1 through a first sealing member 6, and the plug mounting seat 100 is also sleeved with the first sealing member 6, and the plug housing 1 is connected to achieve sealing through the first sealing member 6; similarly, the second tail cover 5 is also connected to the socket housing 2 through a second sealing member 7, and the socket mounting seat 200 is also sleeved with a second sealing member (not shown in the figure), and the socket housing 2 is connected to achieve sealing through the second sealing member.

[0067] It can be seen that the docking connector provided by the present application can immediately identify whether the slot terminal 101 and the plug terminal 201 are assembled to the correct position, so that problems arising during the wiring harness assembly process can be identified in a timely manner to ensure the stability and reliability of product quality; and the docking connector provided by the present application has a simple structure, which greatly improves the assembly process of the product and improves the reliability and stability of the product.

[0068] Finally, it should be noted that the docking connector provided in the present application is not limited to use in new energy vehicles, but can also be used in any equipment or device that requires assembly of wiring harnesses without any special limitations.
