Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle charging interface technology, and in particular to a vehicle socket. Background Technology

[0002] With the advancement and development of technology, the use of new energy vehicles is becoming increasingly widespread. New energy vehicles contain various electrical components, including vehicle sockets. Currently, there are two main types of vehicle sockets for new energy vehicles on the market:

[0003] I. Most existing new energy vehicle sockets adopt a high-low common cavity design and do not support direct insertion of wire harnesses. There are as many as 6 low-voltage signal lines (including temperature sensing) and 3 to 5 high-voltage lines. The high and low voltage lines and their terminals need to pass through the same large tail cover, wire outlet sealing ring and terminal fixing parts. This structural setting does not support direct insertion of wire harnesses, cannot realize automated assembly of the socket body, and the common cavity design leads to low reliability of insulation and sealing failures.

[0004] Second, while some existing new energy vehicle sockets use high-voltage direct insertion, they still employ a common cavity design, failing to achieve isolation between high and low voltage phase sequences. The socket body is composed of numerous components, and the NTC temperature sensor on the signal integration PCBA board is perpendicular to the terminal contact surface, resulting in an unreasonable arrangement and poor temperature detection performance. Summary of the Invention

[0005] Purpose of the invention: To provide a vehicle socket to solve the problems in the prior art where most new energy vehicle sockets do not support direct wiring harness insertion, and the sockets have low insulation reliability and poor temperature detection accuracy.

[0006] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0007] A vehicle socket includes a socket body and a temperature sensing module, the temperature sensing module being connected to the socket body, the socket body including a front panel and a charging module;

[0008] The charging module includes an interface housing with a pre-drilled mounting slot and at least two sets of terminal sockets. The two sets of terminal sockets are respectively for insertion of a low-voltage connection component and a high-voltage connection component. The mounting slot is connected to the terminal sockets for insertion of the high-voltage connection component. The temperature sensing module is connected to the interface housing through the mounting slot.

[0009] The temperature sensing module includes a temperature detection element with a temperature sensing surface, which is parallel and attached to the high-voltage connection assembly to enable the temperature detection element to detect the operating temperature of the high-voltage connection assembly.

[0010] In some possible embodiments, the socket body further includes a first seal, which is disposed at the connection between the front panel and the charging module to achieve a seal between the front panel and the charging module.

[0011] In a further embodiment, the temperature sensing module further includes a temperature sensing housing, a temperature sensing PCBA, and a thermally conductive sleeve, wherein the temperature sensing element is disposed on the temperature sensing PCBA and the temperature sensing element is an NTC temperature sensor.

[0012] The thermally conductive sleeve has an installation area and a conduction area. The thermally conductive sleeve covers the NTC temperature sensor through the installation area and is attached to the high-voltage connection assembly through the conduction area.

[0013] The conductive area is arranged parallel to the temperature sensing surface.

[0014] In a further embodiment, one end of the temperature-sensing housing is a sensing end and the other end is a plug-in end. The temperature-sensing PCBA is located at the sensing end, and the plug-in end is for a low-voltage connector to be inserted.

[0015] The temperature sensing module also includes a conductive component disposed within the temperature sensing housing. The two ends of the conductive component are respectively connected to the sensing end and the plug-in end, for realizing the connection between the low-voltage connector and the temperature sensing PCBA.

[0016] In a further embodiment, the sensing end is inserted into the mounting slot, and a second seal is provided at the connection between the sensing end and the mounting slot. The second seal is used to achieve a seal between the temperature sensing housing and the interface housing.

[0017] In a further embodiment, the high-voltage connection assembly includes an AC terminal, an AC wiring harness, and an AC wire plug, wherein the AC terminal is fixed to one end of the AC wiring harness, and the AC wire plug is sleeved on the AC wiring harness.

[0018] After the AC terminal is inserted into the corresponding terminal socket, the AC plug closes the entrance of the terminal socket.

[0019] In a further embodiment, an anti-retraction limiting member is also provided between the AC terminal and the temperature sensing housing;

[0020] The anti-reverse limiting component includes a flange block and a limiting block. The flange block is disposed on the AC terminal, and the limiting block is fixed to the sensing end.

[0021] The limiting block and the flange block are arranged sequentially in the mounting direction in which the AC terminal moves toward the terminal socket.

[0022] In a further embodiment, the limiting block has a support portion and a limiting portion on the side facing the AC terminal;

[0023] The supporting part is correspondingly provided with the AC terminal, and the limiting part is correspondingly provided with the flange block;

[0024] After the limiting block is connected to the AC terminal through the support part, the flange block abuts against the limiting part.

[0025] In a further embodiment, the AC terminal has a temperature sensing area, the shape of which is adapted to the shape of the conductive area;

[0026] After the AC terminal is inserted into the corresponding terminal socket, the temperature detection area is attached parallel to the conduction area.

[0027] In a further embodiment, the charging module is inserted into the front panel and fastened to the front panel.

[0028] The beneficial effects of the present invention are as follows: by setting a charging module that is assembled with the front panel through a snap-fit ​​structure, the assembly of the socket body is more convenient. The charging module is provided with two sets of terminal holes for high and low voltage connection respectively. While ensuring direct insertion operation, the independent cavity setting can also play a reliable insulation role.

[0029] A temperature sensing module that works in conjunction with the charging module is also provided. The structure of the temperature sensing module facilitates the repair of faulty parts and also provides further support and anti-retraction for the AC terminals, reducing the need for additional parts to limit the AC terminals.

[0030] The NTC temperature sensor included in the temperature detection module can be aligned with the temperature detection area of ​​the AC terminal in the same direction and parallel to the AC terminal after the AC terminal and the socket body are plugged in, so as to achieve the best heat conduction effect.

Detailed Implementation

[0044] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Example 1: Refer to Figure 1 This embodiment discloses a vehicle socket, which includes a socket body 100 and a temperature sensing module 200, wherein the temperature sensing module 200 is connected to the socket body 100.

[0047] The socket body 100 includes a front panel 110 and a charging module 120. The charging module 120 is inserted into the front panel 110 and connected to it via a snap-fit ​​mechanism. Optionally, the snap-fit ​​connection is achieved using a snap-fit ​​assembly structure. The snap-fit ​​assembly utilizes the connection and cooperation of a snap-fit ​​and a snap-fit ​​slot. One of the mounting positions of the charging module 120 and the front panel 110 for mounting the charging module 120 is provided with a snap-fit, and the other is provided with a snap-fit ​​slot. The snap-fit ​​assembly avoids the use of screws for fixing, resulting in a smaller envelope for the charging module 120.

[0048] Furthermore, to prevent water from entering the rear end from the front end, the socket body 100 also includes a first sealing member 130. The first sealing member 130 is disposed at the connection between the front panel 110 and the charging module 120 to achieve a seal between the front panel 110 and the charging module 120, with the rear end being the vehicle interior.

[0049] Optionally, the first seal 130 is a rubber sealing ring, which is arranged around the connection position between the charging module 120 and the front panel 110 to achieve full sealing protection.

[0050] like Figure 11 As shown, the charging module 120 includes an interface housing 121, which has at least two sets of terminal sockets. The two sets of terminal sockets are respectively used for the low-voltage connection component 300 and the high-voltage connection component 400 to be inserted. By setting two sets of terminal sockets, not only can the requirement of direct insertion of wire harness be met, but the low-voltage connection component 300 and the high-voltage connection component 400 can also be independently separated. This non-compartment structure effectively plays a reliable insulating role.

[0051] Furthermore, refer to Figure 2 The interface housing 121 has a pre-drilled mounting slot 124 for installing the temperature sensing module 200. The mounting slot 124 is connected to the terminal socket into which the high-voltage connection assembly 400 is inserted. The mounting slot 124 is located on the side of the interface housing 121, so that after the temperature sensing module 200 is installed through the mounting slot 124, the sensing surface can be parallelly attached to the high-voltage connection assembly 400, achieving the purpose of efficient temperature measurement.

[0052] Furthermore, refer to Figure 6 The high-voltage connection assembly 400 includes an AC terminal 410, an AC wiring harness 420, and an AC wire plug 430. The AC terminal 410 is fixed to one end of the AC wiring harness 420, and the AC wire plug 430 is sleeved on the AC wiring harness 420.

[0053] like Figure 11As shown, after the AC terminal 410 is inserted into the corresponding terminal socket, the AC line plug 430 closes the entrance of the terminal socket.

[0054] Reference Figure 11 and Figure 12 The low-voltage connection assembly 300 includes a signal terminal 310, a signal harness 320, and a signal plug 330. The signal terminal 310 is fixed to one end of the signal harness 320, and the signal plug 330 is sleeved on the signal harness 320. After the signal terminal 310 is inserted into the corresponding terminal socket, the signal plug 330 closes the entrance of the terminal socket. Figure 10 As shown, the first socket 122 is a terminal socket for inserting AC terminal 410, and the second socket 123 is a terminal socket for inserting signal terminal 310.

[0055] The temperature sensing module 200 includes a temperature sensing element 210 with a temperature sensing surface. The temperature sensing element 210 is configured such that when the high-voltage connection component 400 is inserted into the charging module 120 through the corresponding terminal socket, the temperature sensing surface is in parallel contact with the high-voltage connection component 400, thereby realizing the detection of the operating temperature of the high-voltage connection component 400.

[0056] Specifically, such as Figure 3 As shown, the temperature sensing module 200 also includes a temperature sensing housing 220, a temperature sensing PCBA 230, and a thermally conductive sleeve 240. The temperature sensing element 210 is disposed on the temperature sensing PCBA 230 and is an NTC temperature sensor.

[0057] The thermally conductive sleeve 240 has an installation area and a conduction area. The thermally conductive sleeve 240 covers the NTC temperature sensor through the installation area and is attached to the high-voltage connection assembly 400 through the conduction area. The conduction area is arranged parallel to the temperature sensing surface. The thermally conductive sleeve 240 detects the temperature of the high-voltage connection assembly 400 and covers the temperature sensing PCBA 230 for thermal conduction and insulation.

[0058] Optionally, the mounting area has a groove-like structure, allowing the thermally conductive sleeve 240 to be fitted over the NTC temperature sensor through the groove, thus completing the installation of the thermally conductive sleeve 240 and the NTC temperature sensor. After the thermally conductive sleeve 240 and the NTC temperature sensor are installed, refer to... Figure 9 One side of the conductive area is attached to the temperature sensing surface of the NTC temperature sensor, while the opposite side can be attached to the high-voltage connection component 400. The contact surfaces of the NTC temperature sensor and the high-voltage connection component 400 are parallel to each other, resulting in optimal heat conduction.

[0059] Furthermore, such as Figure 4As shown, one end of the temperature sensing housing 220 is a sensing end, and the other end is a plug-in end. The temperature sensing PCBA 230 is located at the sensing end, and the plug-in end is for the low-voltage connector 600 to be inserted.

[0060] Reference Figure 5 The temperature sensing module 200 further includes a conductive member 221 disposed in the temperature sensing housing 220. The two ends of the conductive member 221 are respectively connected to the sensing end and the plug-in end, so as to realize the connection between the low-voltage connector 600 and the temperature sensing PCBA 230.

[0061] Optionally, the conductor 221 is a copper busbar and pins soldered to both ends of the copper busbar. One set of pins is located at the sensing end and connected to the temperature sensing PCBA 230, while the other set of pins is located at the plugging end for connection to the low-voltage connector 600, thereby facilitating the quick-connect operation of the low-voltage connector 600.

[0062] Reference Figure 7 The sensing end is inserted into the mounting slot 124, and a second sealing element 250 is provided at the connection between the sensing end and the mounting slot 124. The second sealing element 250 is used to achieve a seal between the temperature sensing housing 220 and the interface housing 121.

[0063] To better ensure the connection stability of AC terminal 410, such as Figure 7 and Figure 8 As shown, an anti-retraction limiting member is also provided between the AC terminal 410 and the temperature sensing housing 220.

[0064] Specifically, the anti-reverse limiting component includes a flange block 411 and a limiting block 260. The flange block 411 is disposed on the AC terminal 410, and the limiting block 260 is fixed to the sensing end.

[0065] In the mounting direction in which the AC terminal 410 moves toward the terminal socket, the limiting block 260 and the flange block 411 are arranged in sequence;

[0066] The limiting block 260 has a support portion 261 and a limiting portion 262 on the side facing the AC terminal 410.

[0067] Furthermore, the support portion 261 is correspondingly provided with the AC terminal 410, and the limiting portion 262 is correspondingly provided with the flange block 411;

[0068] After the limiting block 260 is connected to the AC terminal 410 via the support part 261, the flange block 411 abuts against the limiting part 262. (Refer to...) Figure 7 and Figure 9The installation direction is the direction in which the terminal moves from the socket inlet into the interface housing 121, and the disassembly direction is the direction in which the terminal moves from the interface housing 121 into the socket inlet. The limiting block 260 is located between the flange block 411 and the inlet, so that after the support part 261 supports the AC terminal 410, the flange block 411 is separated by the limiting block 260. The flange block 411 is located on the side of the limiting block 260 away from the inlet, so that the AC terminal 410 can be prevented from moving backward in the disassembly direction, thus playing an effective stopping role.

[0069] Optional, such as Figure 9 As shown, the support portion 261 is a curved groove, and the curvature of the groove matches the curvature of the position where the AC terminal 410 is connected, so that the AC terminal 410 can be further supported at the support portion 261. At the same time, the limiting portion 262 is located on the side of the support portion 261, so that the flange block 411 provided on the AC terminal 410 can be correspondingly abutted against the limiting portion 262.

[0070] Optionally, the number, shape, and position of the support portion 261 and the limiting portion 262 are adapted to the number, shape, and position of the AC terminal 410.

[0071] Furthermore, in order to improve the temperature detection effect, the AC terminal 410 has a temperature detection area 412, the shape of which is adapted to the shape of the conductive area;

[0072] After the AC terminal 410 is inserted into the corresponding terminal socket, the temperature detection area 412 is attached parallel to the conduction area.

[0073] Optionally, the temperature detection area 412 can be a completed curved surface or a plane.

[0074] In order to achieve a tight connection between the temperature sensing module 200 and the socket body 100, refer to Figure 1 and Figure 11 Optionally, the temperature sensing module 200 is connected to the socket body 100 via fasteners 500.

[0075] Optionally, fastener 500 is a riveted component.

[0076] Furthermore, the rivet passes through the first connecting hole and the second connecting hole to fix the temperature sensing housing 220 to the interface housing 121;

[0077] One of the temperature-sensing housing 220 and the interface housing 121 has the first connection hole, and the other has the second connection hole.

[0078] Optionally, the first connecting hole and / or the second connecting hole are threaded holes, and the riveting component is a screw.

[0079] Optionally, the temperature sensing housing 220 can also be connected to the interface housing 121 by means of snap-fit, plastic ultrasonic welding or laser welding, so as to ensure that the temperature sensing module 200 is effectively connected to the socket body 100 while meeting the high-efficiency detection requirements of the temperature sensing module 200 for the operating temperature of the high-voltage connection component 400.
