Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically to a high-voltage plug connector and a high-voltage connector assembly. Background Technology

[0002] Connectors are primarily used for the mating assembly of equipment and circuits, enabling reliable transmission of current and electrical signals, and are widely used in various fields. The terminals of a connector must maintain a defined mating method during insertion to ensure reliable circuit connection and signal transmission. In actual assembly conditions, due to limitations imposed by the layout of surrounding components, cavity structure, and installation space, connectors with fixed shapes are prone to structural positional interference. Forcing alignment not only fails to achieve successful terminal insertion and conduction but also leads to assembly misalignment and mating failure, severely impacting circuit stability and the normal operation of the entire device. Therefore, there is an urgent need for a connector that can flexibly adjust the orientation and position of the bends according to the actual installation environment while maintaining the terminal insertion method, thereby effectively avoiding structural interference and possessing high installation adaptability and operational reliability. Summary of the Invention

[0007] A fastener is disposed between the elbow housing and the connecting housing to fix the elbow housing and the connecting housing in the axial direction. The elbow housing can rotate circumferentially relative to the connecting housing. When the elbow housing and the connecting housing are connected, the first connecting portion covers the second connecting portion at the first end of the second contact member.

[0008] Optionally, a circumferential limiting groove is provided on the ring wall, and an elastic support is disposed in the limiting groove.

[0009] Optionally, the fastener is a retaining ring; the outer wall of the elbow housing is provided with a first retaining groove, and the inner wall of the connecting housing is provided with a second retaining groove. When the elbow housing and the connecting housing are connected, the retaining ring is embedded in the first retaining groove and the second retaining groove.

[0010] Optionally, the high-voltage plug connector further includes a first waveform shielding gasket, which is disposed inside the connecting housing and surrounds the first end of the second contact. When the elbow housing is connected to the connecting housing, the first waveform shielding gasket is pressed against the connecting housing by the end of the elbow housing.

[0011] Optionally, the high-voltage plug connector further includes a first seal, which is fitted over the elbow housing. When the elbow housing is connected to the connecting housing, the first seal abuts against the inner wall of the connecting housing to seal the gap between the elbow housing and the connecting housing.

[0012] Optionally, the second end of the first contact is provided with a third connecting portion for connecting to the cable, and the third connecting portion extends to the outside of the elbow housing; the elbow assembly also includes a cable end inner shell, a cable end outer shell, a cable end seal, and a cable end cap, the cable end inner shell is mated with the elbow housing, the cable end inner shell is used to surround the third connecting portion and the cable, the cable end outer shell is sleeved on the cable end inner shell and fixedly connected to the elbow housing; the cable end cap is fixedly connected to the tail of the cable end outer shell to limit the cable end seal to the tail of the cable end outer shell; when the cable is connected to the third connecting portion, the cable end seal is sleeved on the cable.

[0013] According to a second aspect, the present invention provides a high-voltage connector assembly, comprising:

[0014] The high-voltage plug connector in the first aspect or any embodiment of the first aspect.

[0015] A socket connector includes a socket housing and a third contact fixed inside the socket housing. The first end of the socket housing is provided with a mating cavity, and the first end of the third contact is provided with a fourth connecting part.

[0016] When the high-voltage plug connector and the socket connector are plugged in, the connecting shell is inserted into the plugging cavity, the third contact is connected to the second contact, and the fourth connecting part covers the second connecting part at the second end of the second contact.

[0017] Optionally, the socket connector further includes a first locking element disposed on the socket housing;

[0020] Optionally, the first locking element is a locking pin;

[0021] The second locking component includes two rotary locking arms and a connecting arm connected between the two rotary locking arms. The two rotary locking arms are arranged opposite to each other and can be rotatably connected to the outer wall of the connecting housing. Both rotary locking arms are provided with locking grooves.

[0022] When the plug connector and the socket connector are inserted, rotate the locking arm until the locking post is embedded in the locking groove, the second locking element is in the locked state, and the high-voltage plug connector is locked onto the socket connector.

[0023] Optionally, the high-voltage plug connector further includes a locking element, which includes a sliding base and a locking arm and a snap-fit ​​spring arm disposed on the sliding base. The end of the snap-fit ​​spring arm is provided with a first snap-fit ​​portion. The connecting housing is provided with a sliding track that matches the sliding base and a second snap-fit ​​portion that corresponds to the first snap-fit ​​portion. When the sliding base slides along the sliding track to the locking position, the first snap-fit ​​portion and the second snap-fit ​​portion snap together.

[0024] When the second locking element is in the locked state, the connecting arm is attached to the connecting housing; when the sliding seat slides to the locking position, the locking arm extends onto the connecting arm, locking the connecting arm between the locking arm and the connecting housing.

[0025] The technical solution of this invention has the following advantages:

[0026] 1. The high-voltage plug connector provided by the present invention comprises two parts: an elbow assembly and a connecting assembly. The elbow assembly has an elbow shell, and the connecting assembly has a connecting shell. While the two are axially fixed by a fixing member, the elbow shell can also rotate circumferentially relative to the connecting shell. This allows the high-voltage plug connector to achieve a stable and reliable connection with the mating connector (i.e., a socket connector) through the first contact member in the connecting assembly. Furthermore, the rotation of the elbow assembly relative to the connecting assembly allows for flexible adjustment of the elbow's orientation and position, effectively avoiding structural interference and ensuring that the high-voltage plug connector can be smoothly connected to the circuit (to connect with cables), thus improving its installation adaptability and reliability.

[0027] Furthermore, by setting a second connecting portion at both the first end and the second section of the connecting assembly, the second connecting portion has a hollow cavity, and several opening slots are provided on the annular wall of the second connecting portion. An elastic support member is provided inside the hollow cavity, and the elastic support member is arranged circumferentially along the annular wall, generating a supporting force on the annular wall away from the hollow cavity. When the elbow assembly and the connecting assembly are connected, the first connecting portion of the first contact member in the elbow assembly covers the second connecting portion at the first end of the second contact member, so that the inner diameter of the first contact member and the inner diameter of the second contact member can be set to be the same (based on the setting of the opening slots). This maximizes the contact area between the first contact member and the second contact member when they mate (based on the setting of the same inner and outer diameters and the external support effect of the elastic support member), ultimately giving the high-voltage plug connector better heat dissipation.

[0057] Furthermore, to provide a concise description of exemplary embodiments, not all features of actual embodiments (i.e., those features not related to the currently considered best mode for carrying out the invention, or those features not related to implementing the invention) may be omitted. Moreover, the technical features involved in the different embodiments of the invention described below may be combined with each other as long as they do not conflict with each other. Example 1

[0058] Please refer to Figures 1-5 This is a schematic diagram of the high-voltage plug connector provided in an embodiment of the present invention.

[0059] like Figures 1-5 As shown, the high-voltage plug connector includes an elbow assembly 110, a connecting assembly 120, and a fixing member 130. The elbow assembly 110 includes an elbow housing 111 and a first contact 112 fixed within the elbow housing 111; the first end of the first contact 112 is provided with a first connecting portion 112a. The connecting assembly 120 includes a connecting housing 121 and a second contact 122 fixed within the connecting housing 121; both the first and second ends of the second contact 122 are provided with second connecting portions 122a, the second connecting portions 122a having a hollow cavity, and the annular wall of the second connecting portions 122a having a plurality of openings 122a1; the hollow cavity... An elastic support 123 is provided inside, which is arranged circumferentially along the ring wall and generates a supporting force on the ring wall away from the hollow cavity; a fixing member 130 is provided between the elbow housing 111 and the connecting housing 121 to fix the elbow housing 111 and the connecting housing 121 in the axial direction, and the elbow housing 111 can rotate circumferentially relative to the connecting housing 121; when the elbow housing 111 is connected to the connecting housing 121, the first connecting part 112a covers the second connecting part 122a at the first end of the second contact member 122.

[0060] In specific implementation, a circumferentially oriented limiting groove 122a2 can be provided on the ring wall, and an elastic support member 123 can be disposed in the limiting groove 122a2.

[0061] In specific implementation, the fixing member 130 can be set as a retaining ring. At this time, the outer wall of the elbow housing 111 is provided with a first retaining groove 1111, and the inner wall of the connecting housing 121 is provided with a second retaining groove 1211. When the elbow housing 111 and the connecting housing 121 are connected, the retaining ring is embedded in the first retaining groove 1111 and the second retaining groove 1211.

[0062] In this embodiment, to ensure the sealing of the high-voltage plug connector, such as Figures 2-4As shown, the high-voltage plug connector may also include a first sealing element 140. The first sealing element 140 is sleeved on the outside of the elbow housing 111. When the elbow housing 111 is connected to the connecting housing 121, the first sealing element 140 abuts against the inner wall of the connecting housing 121 to seal the gap between the elbow housing 111 and the connecting housing 121.

[0063] In this embodiment, to ensure the electromagnetic shielding effect of the high-voltage plug connector, such as Figure 2 As shown, the high-voltage plug connector may also include a first waveform shielding gasket 150. The first waveform shielding gasket 150 is disposed inside the connecting housing 121 and surrounds the first end of the second contact 122. When the elbow housing 111 is connected to the connecting housing 121, the first waveform shielding gasket 150 is pressed against the connecting housing 121 by the end of the elbow housing 111.

[0064] In this embodiment, as Figure 3 The first contact 112 has a third connecting part 112b at its second end, which is used to connect to a cable.

[0065] In this embodiment, the elbow housing 111 can be configured to rotate 180 degrees relative to the connecting housing 121; specifically, with Figure 1 Taking the elbow assembly 110 described above as having a vertical downward angle of 0 degrees and not rotated as an example, the rotatable range of the elbow assembly 110 is from 90 degrees counterclockwise to 90 degrees clockwise.

[0066] As an optional specific implementation of this embodiment, in order to facilitate the assembly between the cable and the first contact 112, and to ensure the structural sealing after assembly, such as Figure 3 As shown, the third connecting portion 112b of the first contact 112 can be extended to the outside of the elbow housing 111, and the elbow assembly 110 can also include a wire end inner housing 161, a wire end housing 162, a wire end seal 163, and a wire end cap 164. The wire end inner housing 161 is mated with the elbow housing 111 and is used to surround the third connecting portion 112b and the cable. The wire end housing 162 is sleeved on the wire end inner housing 161 and fixedly connected to the elbow housing 111. The wire end cap 164 is fixedly connected to the tail of the wire end housing 162 to limit the wire end seal 163 to the tail of the wire end housing 162. When the cable is connected to the third connecting portion 112b, the wire end seal 163 is sleeved on the cable.

[0067] In specific implementation, the fixed connection between the wire end housing 162 and the elbow housing 111, and the fixed connection between the wire end cap 164 and the wire end housing 162, can all be set as threaded detachable fixed connections.

[0068] In this embodiment, in order to further improve the structural sealing performance after assembly, such as Figure 3 As shown, the elbow assembly 110 may also include a second sealing element 165, which is sleeved on the elbow housing 111. When the line end housing 162 is fixedly connected to the elbow housing 111, the second sealing element 165 abuts against the inner wall of the line end housing 162 to seal the gap between the line end housing 162 and the elbow housing 111.

[0069] The high-voltage plug connector in this embodiment comprises two parts: a bend assembly 110 and a connecting assembly 120. The bend housing 111 in the bend assembly 110 and the connecting housing 121 in the connecting assembly 120 are axially fixed by the fixing member 130. Simultaneously, the bend housing 111 can rotate circumferentially relative to the connecting housing 121. This allows the high-voltage plug connector to achieve a stable and reliable connection with the mating connector (i.e., the socket connector) via the first contact member 112 in the connecting assembly 120. Furthermore, the rotation of the bend assembly 110 relative to the connecting assembly 120 allows for flexible adjustment of the bend's orientation and position, effectively avoiding structural interference and ensuring smooth circuit connection (to cables), thus improving its installation adaptability and operational reliability.

[0070] Furthermore, by providing a second connecting portion 122a at both the first end and the second section of the connecting assembly 120, the second connecting portion 122a has a hollow cavity, and a plurality of opening slots 122a1 are provided on the annular wall of the second connecting portion 122a. An elastic support member 123 is provided inside the hollow cavity. The elastic support member 123 is arranged circumferentially along the annular wall, generating a supporting force away from the hollow cavity on the annular wall. When the elbow assembly 110 and the connecting assembly 120 are connected, the first connecting portion 112a of the first contact member 112 in the elbow assembly 110 covers the second connecting portion 122a at the first end of the second contact member 122, so that the inner diameter of the first contact member 112 and the inner diameter of the second contact member 122 can be set to be the same (based on the setting of the opening slots 122a1). This maximizes the contact area between the first contact member 112 and the second contact member 122 when they are mated (based on the setting of the same inner and outer diameters and the external support effect of the elastic support member 123), ultimately giving the high-voltage plug connector better heat dissipation. Example 2

[0071] Please refer to Figures 6-9 This is a structural schematic diagram of the high-voltage connector assembly provided in an embodiment of the present invention, as shown below. Figures 6-9 As shown, the high-voltage connector assembly includes a high-voltage plug connector 100 and a socket connector 200 as described in any embodiment of Example 1. Figure 8As shown, the socket connector 200 includes a socket housing 210 and a third contact 220 fixed inside the socket housing 210. The first end of the socket housing 210 is provided with a mating cavity, and the first end of the third contact 220 is provided with a fourth connecting portion 220a.

[0072] In this embodiment, when the high-voltage plug connector 100 and the socket connector 200 are plugged in, the connecting housing 121 is plugged into the plugging cavity, the third contact 220 is connected to the second contact 122, and the fourth connecting part 220a covers the second connecting part 122a at the second end of the second contact 122.

[0073] In specific implementation, to further ensure the sealing performance of the high-voltage connector assembly in this embodiment, such as... Figure 6 and Figure 9 As shown, the high-voltage connector assembly may also include a third seal 300, which is disposed on the connecting housing 121 and located at the end of the connecting housing 121 away from the elbow housing 111; when the high-voltage plug connector 100 and the socket connector 200 are inserted, the third seal 300 abuts against the wall of the insertion cavity to seal the gap between the connecting housing 121 and the socket housing 210.

[0074] In specific implementation, in order to further ensure the electromagnetic shielding effect of the high-voltage connector assembly in this embodiment, the high-voltage connector assembly in this embodiment may be further provided with a second waveform shielding gasket. The second waveform shielding gasket is disposed inside the socket housing 210 and surrounds the first end of the third contact 220. When the high-voltage plug connector 100 and the socket connector 200 are plugged in, the second waveform shielding gasket is pressed against the socket housing 210 by the end of the connecting housing 121.

[0075] As an optional implementation of this embodiment, in order to improve the structural stability of the high-voltage plug connector 100 and the socket connector 200 when they are plugged in, such as Figure 6 and Figure 7 As shown, the socket connector 200 may also include a first locking member 230, which is disposed on the socket housing 210; the high-voltage plug connector 100 may also include a second locking member 170, which is disposed on the connection housing 121; when the plug connector and the socket connector 200 are plugged in, the second locking member 170 may cooperate with the first locking member 230 to lock the high-voltage plug connector 100 onto the socket connector 200.

[0076] As an optional specific implementation method, such as Figure 6 and Figure 7As shown, the first locking member 230 can be set as a locking post 231; the second locking member 170 includes two rotary locking arms 171 and a connecting arm 172 connected between the two rotary locking arms 171. The two rotary locking arms 171 are arranged opposite to each other and can be rotatably connected to the outer wall of the connecting housing 121. Both rotary locking arms 171 are provided with locking grooves 171a. When the plug connector and the socket connector 200 are plugged in, the rotary locking arms 171 are rotated until the locking post 231 is embedded in the locking groove 171a. The second locking member 170 is in a locked state, and the high-voltage plug connector 100 is locked on the socket connector 200.

[0077] As an optional implementation of this embodiment, in order to further improve the structural stability of the high-voltage plug connector 100 and socket connector 200 when they are plugged in, such as... Figures 6-10 As shown, the high-voltage plug connector 100 may also include a locking member 180. The locking member 180 includes a sliding base 181 and a locking arm 182 and a snap-fit ​​spring arm 183 disposed on the sliding base 181. The end of the snap-fit ​​spring arm 183 is provided with a first snap-fit ​​part 183a. The connecting housing 121 is provided with a sliding track 1212 that matches the sliding base 181 and a second snap-fit ​​part 1213 that corresponds to the first snap-fit ​​part 183a. When the sliding base 181 slides along the sliding track 1212 to the locking position, the first snap-fit ​​part 183a and the second snap-fit ​​part 1213 snap-fit ​​together. When the second locking member 170 is in the locked state, the connecting arm 172 is attached to the connecting housing 121. When the sliding base 181 slides to the locking position, the locking arm 182 extends onto the connecting arm 172, locking the connecting arm 172 between the locking arm 182 and the connecting housing 121.

[0078] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
