Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a socket connector and a battery pack. Background Technology

[0002] Pure electric commercial vehicles have large battery capacities and various battery configurations. To meet the battery capacity requirements of different models, commercial vehicles design battery packs as standard packs with different cell capacities. These standard battery packs do not contain contactors, and the battery input and output circuits are always energized. The input and output interfaces of the battery packs mostly use quick-connect connectors. The socket connector is mounted on the side wall of the battery pack housing, while the plug connector connects the cable. The plug and socket connectors are mated together to connect the circuitry. To prevent electromagnetic interference, the connector terminals are surrounded by a shielding structure. The shielding structure of the plug connector is connected to the cable shielding layer, and the shielding structure of the socket connector is connected to the side wall of the battery pack housing. After the plug and socket connectors are mated, their shielding structures make contact and conduct electricity.

[0003] The shielding structure of a socket connector typically employs a cylindrical shield. The main body of the shield is fitted onto a protruding post within the housing, where the mating terminals are mounted. The outer wall of the main body of the shield contacts the shielding structure of the plug connector. The tail end of the shield extends from the inside out to the tail end of the connector housing. After the tail end of the socket connector is mounted against the side wall of the battery pack housing, the portion of the shield extending through the housing and located at the tail end of the connector can abut against the side wall of the battery pack housing, establishing electrical conductivity with the metal housing. To allow the shielding structure to extend through the connector housing, corresponding shielding perforations are provided on the connector housing. To achieve a seal for the socket connector, sealing elements are required on both the inner and outer sides of the shielding perforations perpendicular to the connector mating direction. This necessitates space on the connector housing inside the shielding perforations for installing the sealing elements. Consequently, the shield must be installed around the inner sealing element. The shield's dimensions perpendicular to the connector mating direction are relatively large. Consequently, to accommodate mating, the overall size of the socket connector is large, occupying significant space and hindering cost savings. Utility Model Content

[0004] The purpose of this utility model is to provide a socket connector to solve the problem that the shielding structure of current socket connectors results in a large size and occupies a lot of space; the purpose of this utility model is also to provide a battery pack to solve the above problems.

[0005] The technical solution of the socket connector of this utility model is as follows:

[0006] A socket connector includes a socket housing and a shield. The socket housing has a mounting surface for abutting against a device housing and a mating cavity for inserting a plug connector. The mating cavity has a mating protrusion for inserting the plug connector, and a mating terminal is provided in the mating protrusion. The shield includes a main body fitted onto the mating protrusion. One end of the main body near the bottom of the mating cavity has an outwardly flared edge, and the end of the outwardly flared edge away from the main body has a shielding protrusion. The socket housing has a shielding through hole that passes through the mating cavity and the mounting surface. The shielding protrusion passes through the shielding through hole, and the end of the shielding protrusion extending to the mounting surface has a shielding contact portion for contacting the device housing. A sealing structure for mating with the device housing is provided on the mounting surface around the shielding protrusion.

[0007] Beneficial Effects: This utility model improves upon existing socket connectors by designing the shielding cover with different front and rear dimensions to accommodate the space required for both the sealing structure and the plug terminals. The plug terminals are installed in the plugging protrusion within the plugging cavity of the socket housing. The main body of the shielding cover fits snugly onto the plugging protrusion. An outward-flared edge is provided at the rear end of the shielding cover, and a shielding protrusion portion is designed to pass through the shielding perforation in the socket housing. This allows the shielding protrusion portion to be offset from the main body in the plugging direction, with the protrusion portion positioned further outward relative to the socket centerline than the main body. This provides sufficient space inside the shielding protrusion portion for the sealing structure, ensuring the proper sealing of the outer perimeter of the shielding protrusion portion. In terms of space, after the socket connector is installed on the equipment housing, the mounting surface of the socket housing rests against the equipment housing, and the sealing structure mates with the equipment housing to form a seal at the shielding perforation. In this way, the outward-flaring edge makes the shielding protrusion part misaligned with the main body, forming a stepped shielding cover. The front and rear dimensions are different along the connector insertion direction. The shielding protrusion part utilizes the larger arrangement space formed by the part between the mounting surface of the socket housing and the bottom of the insertion cavity to meet the arrangement requirements of the shielding cover and sealing structure. The size of the main body is smaller, which meets the arrangement of the insertion terminals while reducing the size. This can reduce the dimension of the part of the socket housing where the insertion cavity is located perpendicular to the insertion direction, thereby reducing the overall size of the socket connector, avoiding excessive space occupation, and helping to save costs.

[0008] Furthermore, the shielding cover is formed by bending an integral sheet, with the two ends of the sheet joined together to form the main body of the shielding cover.

[0009] Furthermore, the inner opening of the shielding perforation in the plug cavity constitutes an inlet for the shielding protrusion to pass through from the plug cavity to the mounting surface, and the shielding contact part is a spring claw provided at the end of the shielding protrusion.

[0010] Furthermore, the pawl is turned outward relative to the shielding penetration part.

[0011] Furthermore, the mounting surface is provided with a sealing groove for installing a sealing structure, and the sealing groove is connected to the shielding perforation.

[0012] Furthermore, the sealing structure is a sealing ring, which is arranged to surround the center line of the socket connector. The sealing ring has a ring-shaped surrounding part on its body. The surrounding part is arranged around the periphery of the shielding perforation to cooperate with the equipment housing to form a seal on the part of the shielding perforation that passes through the socket housing.

[0013] Furthermore, the main cylinder has a rectangular structure, and the four side walls of the main cylinder are provided with the aforementioned outward flanges, with at least two opposite outward flanges having the aforementioned shielding protrusions.

[0014] Furthermore, the outward-curved edge presses against the bottom of the insertion cavity.

[0015] Furthermore, the socket connector includes power terminals and signal terminals, both of which are plug-in terminals, and each plug-in terminal is located within the area enclosed by the shield.

[0016] The technical solution of the battery pack of this utility model is as follows:

[0017] A battery pack includes a battery pack housing and a socket connector fixedly mounted on the side wall of the battery pack housing. The battery pack constitutes a device on which the socket connector is mounted. The socket connector includes a socket housing and a shield. The socket housing has a mounting surface for abutting against the device housing and a mating cavity for inserting a plug connector. The mating cavity has a mating protrusion for inserting the plug connector, and the mating protrusion has a mating terminal. The shield includes a main cylinder that fits onto the mating protrusion. One end of the main cylinder near the bottom of the mating cavity has an outwardly flared edge, and the end of the outwardly flared edge away from the main cylinder has a shielding protrusion. The socket housing has a shielding through hole that passes through the mating cavity and the mounting surface. The shielding protrusion passes through the shielding through hole, and the end of the shielding protrusion extending to the mounting surface has a shielding contact portion for contacting the device housing. The mounting surface has a sealing structure around the shielding protrusion for mating with the device housing.

[0018] Beneficial Effects: This utility model improves upon existing battery pack socket connectors by designing the socket connector's shielding cover with different front and rear dimensions to accommodate the space required for both the sealing structure and the plug-in terminals. The plug-in terminals are installed in the plug-in protrusion within the plug-in cavity of the socket housing. The main body of the shielding cover fits snugly onto the plug-in protrusion. An outward-flared edge is provided at the rear end of the shielding cover, and a shielding protrusion portion is designed along the edge of this edge, allowing it to pass through the shielding perforation in the socket housing. This design causes the shielding protrusion portion to be misaligned with the main body in the plugging direction. The shielding protrusion portion is further outward relative to the socket centerline than the main body, ensuring sufficient space inside the shielding protrusion portion for a sealing structure and guaranteeing a sealed outer perimeter of the shielding protrusion portion. The design incorporates a space where, after the socket connector is installed onto the equipment housing, the mounting surface of the socket housing rests against the equipment housing, and the sealing structure mates with the equipment housing to form a seal at the shielding perforation. This utilizes the outward-flaring edge to offset the shielding protrusion from the main body, creating a stepped shielding structure. The dimensions differ along the connector insertion direction. The shielding protrusion utilizes the larger arrangement space formed between the mounting surface of the socket housing and the bottom of the insertion cavity, satisfying the arrangement requirements of the shielding cover and sealing structure. The main body has a smaller dimension, satisfying the insertion terminal arrangement while reducing overall size. This reduces the dimension of the socket housing's insertion cavity perpendicular to the insertion direction, thereby reducing the overall size of the socket connector, avoiding excessive space occupation, and saving costs.

[0019] Furthermore, the shielding cover is formed by bending an integral sheet, with the two ends of the sheet joined together to form the main body of the shielding cover.

[0020] Furthermore, the inner opening of the shielding perforation in the plug cavity constitutes an inlet for the shielding protrusion to pass through from the plug cavity to the mounting surface, and the shielding contact part is a spring claw provided at the end of the shielding protrusion.

[0021] Furthermore, the pawl is turned outward relative to the shielding penetration part.

[0022] Furthermore, the mounting surface is provided with a sealing groove for installing a sealing structure, and the sealing groove is connected to the shielding perforation.

[0023] Furthermore, the sealing structure is a sealing ring, which is arranged to surround the center line of the socket connector. The sealing ring has a ring-shaped surrounding part on its body. The surrounding part is arranged around the periphery of the shielding perforation to cooperate with the equipment housing to form a seal on the part of the shielding perforation that passes through the socket housing.

[0024] Furthermore, the main cylinder has a rectangular structure, and the four side walls of the main cylinder are provided with the aforementioned outward flanges, with at least two opposite outward flanges having the aforementioned shielding protrusions.

[0025] Furthermore, the outward-curved edge presses against the bottom of the insertion cavity.

[0026] Furthermore, the socket connector includes power terminals and signal terminals, both of which are plug-in terminals, and each plug-in terminal is located within the area enclosed by the shield. Attached Figure Description

[0037] The basic concept of the socket connector on the battery pack of this utility model is to set the shield of the socket connector as a structure with different front and rear dimensions. The shield protrusion part utilizes the larger arrangement space formed by the part between the mounting surface of the socket housing and the bottom of the insertion cavity to meet the arrangement requirements of the shield and the sealing structure. The main body is smaller in size, which meets the arrangement of the insertion terminals while reducing the size. Compared with the conventional straight cylindrical shield, the dimension of the part of the socket housing where the insertion cavity is located perpendicular to the insertion direction can be reduced, thereby reducing the overall size of the socket connector.

[0038] The technical solution of this utility model will be described in detail below with reference to specific embodiments.

[0039] Embodiments of the battery pack of this utility model:

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the battery pack includes a battery pack housing 100 and battery modules disposed within the battery pack housing 100. The side wall of the battery pack housing 100 is the shell side wall, and a socket connector 101 is fixedly installed on the side wall of the battery pack housing 100. This socket connector 101 is adapted to be paired with a plug connector 102. The battery pack has an input end and an output end spaced apart. The aforementioned socket connector 101 is a single-core socket, and only one type of power terminal 13 is provided within the socket connector 101. The power terminal 13 is either a positive or negative power terminal. The input end and the output end are formed by two spaced-apart socket connectors 101. The plug connector 102 adapted to the socket connector 101 is a single-core plug, and only one type of power pin 21 is provided on the plug connector 102. The two socket connectors 101 are respectively connected to the plug connector 102. The power terminal 13 of the socket connector 101 is a jack terminal, which is used to connect with the power pin 21 of the plug connector 102 to achieve power current transmission.

[0041] The socket connector 101 includes a socket housing 11, power terminals 13, signal terminals 14, and a shielding cover 15. Both power terminals 13 and signal terminals 14 are plug-in terminals. The socket housing 11 has a plug-in cavity 12 at its head, and a plug-in protrusion 16 is provided inside the plug-in cavity 12. The plug-in protrusion 16 protrudes from the bottom of the plug-in cavity 12, which is the bottom of the plug-in cavity 12. The power terminals 13 and signal terminals 14 are installed in corresponding mounting holes provided in the plug-in protrusion 16, and the shielding cover 15 is fitted around the plug-in protrusion 16.

[0042] The plug connector 102 includes a plug housing, a power pin 21, an interlocking shorting terminal 22, and a plug shielding structure. The head of the plug housing is provided with a plug central cavity 23 and a plug peripheral annular cavity 24 surrounding the plug central cavity 23. The power pin 21 and the interlocking shorting terminal 22 are located inside the plug central cavity 23. The plug shielding structure has plug shielding contact claws 25 located on the side wall of the plug central cavity 23. The tail end of the plug connector 102 is connected to a cable, and the plug shielding structure is connected to the shielding layer of the cable.

[0043] After the plug connector 102 and the socket connector 101 are inserted, the insertion protrusion 16 and the shielding cover 15 are inserted into the central recess 23 of the plug. The portion of the socket housing 11 located around the insertion protrusion 16 is inserted into the outer ring cavity 24 of the plug. Correspondingly, the portion of the plug housing located between the central recess 23 and the outer ring cavity 24 is inserted into the space of the insertion cavity 12 located around the insertion protrusion 16. The power pin 21 is inserted into the insertion protrusion 16 and contacts the power terminal 13 for conduction. The interlocking shorting terminal 22 is inserted into the two signal terminals 14 of the socket connector 101 to achieve interlocking circuit conduction. The signal terminals 14 transmit low-voltage signals. With the interlocking shorting terminal 22 of the plug, it can detect whether the plug and socket are properly inserted. The interlocking detection circuit is existing technology and will not be described in detail here. The plug shielding contact claw 25 abuts against the outer wall surface of the shielding cover 15 to achieve shielding conduction.

[0044] The power terminal 13 and signal terminal 14 of the socket connector 101 are both located within the area enclosed by the shield 15, which can provide good shielding for each plug-in terminal. In other embodiments, the signal terminal 14 can be arranged outside the shield 15, while the power terminal 13 is located inside the shield 15.

[0045] Combination Figure 6 , Figure 7 , Figure 8 The socket housing 11 has a mounting surface 18 for abutting against the side wall of the battery pack housing 100, which is the device housing on which the socket connector 101 is mounted. The socket housing 11 and the side wall of the battery pack housing 100 are fixedly connected by bolts. The shield 15 has a portion that extends out of the socket housing 11 and forms contact with the metal battery pack housing 100.

[0046] The shielding cover 15 includes a main cylinder 151 that fits over the plug-in protrusion 16. The end of the main cylinder 151 near the bottom of the plug-in cavity 12 is provided with an outward flange 152. The end of the outward flange 152 away from the main cylinder 151 is provided with a shielding protrusion 153. The socket housing 11 is provided with a shielding through hole that passes through the plug-in cavity 12 and the mounting surface 18. The shielding protrusion 153 passes through the shielding through hole and the end of the shielding protrusion 153 that extends to the side of the mounting surface 18 is provided with a shielding contact part 154 for contacting the equipment housing. The mounting surface 18 is provided with a sealing structure around the shielding protrusion 153 for sealing with the side wall of the battery pack housing 100.

[0047] The shield 15 of the socket connector 101 is configured with different front and rear dimensions to accommodate the space required for the sealing structure and the space required for the plug terminals. The plug terminals are installed in the plug protrusion 16 located in the plug cavity 12 of the socket housing 11. The main body 151 of the shield 15 is fitted onto the plug protrusion 16. An outward flange 152 is provided at the rear end of the shield 15. A shield protrusion 153 is provided on the edge of the outward flange 152, which can pass through the shielding through hole of the socket housing 11. The shield protrusion 153 is offset from the main body 151 in the plugging direction. The shield protrusion 153 is further outward relative to the center line of the socket than the main body 151, so that there is enough space inside the shield protrusion 153 to install the sealing structure and ensure the space for the sealing structure around the shield protrusion 153. After the socket connector 101 is installed on the equipment housing, the mounting surface 18 of the socket housing 11 is against the equipment housing and the sealing is achieved. The sealing structure and the equipment housing cooperate to form a seal at the shielding perforation. In this way, the outward flange 152 is used to offset the shielding protrusion 153 from the main cylinder 151, forming a stepped shielding cover 15. The front and rear dimensions are different along the connector insertion direction. The shielding protrusion 153 has a larger arrangement space formed by the part between the mounting surface 18 of the socket housing 11 and the bottom of the insertion cavity 12, which meets the arrangement requirements of the shielding cover 15 and the sealing structure. The main cylinder 151 has a smaller size, which meets the arrangement of the insertion terminals while reducing the size. It can reduce the size of the part of the socket housing 11 where the insertion cavity 12 is located perpendicular to the insertion direction. Compared with the existing straight cylindrical shielding cover 15, the structure of this stepped shielding cover 15 can reduce the size of the insertion protrusion in the insertion cavity where the shielding cover is installed. In this way, the insertion cavity can meet the insertion while avoiding excessive size. It can reduce the overall size of the socket connector 101, avoid occupying too much space, and help save costs.

[0048] The shielding cover 15 is formed by bending an integral sheet material. The two ends of the sheet material are joined together to form the main cylinder 151 of the shielding cover 15. The structure is simple and easy to manufacture. In other embodiments, a split structure can also be adopted, with the shielding protrusion part and the outer flange being set separately. A forced mounting hole is provided on the outer flange, and the shielding protrusion part is interference-fitted into the forced mounting hole.

[0049] The shielding through-hole of the socket housing 11, located within the insertion cavity 12, forms an inlet for the shielding through-hole 153 to pass through the insertion cavity 12 to the mounting surface 18. The shielding contact part 154 is a spring claw located at the end of the shielding through-hole 153. The spring claw forms an elastic contact with the side wall of the battery pack housing 100, which is beneficial for reliable contact. In other embodiments, the spring claw may be omitted, and the shielding contact part may be formed directly by the end face of the shielding through-hole and directly abut against the side wall of the battery pack housing.

[0050] The shielding contact portion 154 is turned outward relative to the shielding protrusion portion 153, causing the spring claw to extend outward. The end of the spring claw has a curved structure, which can better form elastic contact with the side wall of the battery pack housing 100. In other embodiments, the spring claw can also be bent inward if space permits.

[0051] When installing the shielding cover 15, the spring claw is not bent at first. At this time, the extension direction of the spring claw is the same as the extension direction of the shielding protrusion 153, so as to facilitate the smooth installation of the shielding cover 15 from one side of the insertion cavity 12. After installation, the spring claw extends out of the socket housing 11, and then it is bent so that it forms an angle with the shielding protrusion 153, which can be perpendicular. This ensures the smooth installation of the integrated shielding cover 15.

[0052] The main body 151 is clamped to the outer peripheral surface of the insertion protrusion 16. The shielding through-hole of the socket housing 11 is spaced apart from the insertion protrusion 16 and located at the bottom of the insertion cavity 12. The outward flange 152 is perpendicular to the side of the main body 151, the shielding protrusion 153 is perpendicular to the outward flange 152, and the shielding contact 154 is perpendicular to the shielding protrusion 153. The extending direction of the shielding protrusion 153 is consistent with the extending direction of the side of the main body 151. The centerline direction of the socket connector 101 is its insertion direction, and the centerline direction of the main body 151 is consistent with the centerline direction of the socket connector 101.

[0053] The main cylinder 151 has a rectangular structure. Each of the four side walls of the main cylinder 151 has an outwardly turned edge 152, spaced apart from each other. The outwardly turned edges 152 on two opposite long sides have shielding protrusions 153, while those on the short sides do not. Shielding protrusions 153 are provided at both ends along the length of the same outwardly turned edge 152, ensuring the structural strength of the shielding cover 15 while increasing the number of contact points. In other embodiments, each outwardly turned edge may also have a shielding protrusion.

[0054] The outward-curved edge 152 flares outward relative to the inner cavity of the main cylinder 151. After the shielding cover 15 is installed in place, the outward-curved edge 152 presses against the bottom of the insertion cavity 12, limiting the shielding cover 15 and ensuring reliable force when the plug connector 102 is inserted. In other embodiments, the outward-curved edge may not contact the bottom of the insertion cavity.

[0055] The shielding perforations of the socket housing 11 correspond one-to-one with the shielding protrusions 153 of the shielding cover 15. The four shielding perforations are distributed at the four corners of the rectangle. The sealing structure that can seal the shielding perforations is an interface sealing ring 17. The mounting surface 18 is provided with a sealing groove for mounting the interface sealing ring 17. The sealing groove is connected to the shielding perforations, which can save the space required for arranging the sealing structure and help reduce the size of the connector. In other embodiments, the sealing groove and the shielding perforations may not be connected, but are independent of each other. In this case, the sealing groove has an outer space surrounding the shielding perforations and located outside the shielding perforations. The portion of the interface sealing ring located inside this outer space can seal the shielding perforation area.

[0056] The interface sealing ring 17 constitutes the sealing structure. The interface sealing ring 17 is arranged around the center line of the socket connector 101, and a corresponding sealing groove is located on the periphery of the area surrounding the insertion terminals on the socket housing 11. The interface sealing ring 17 presses against the side wall of the battery pack housing 100 to form a seal, preventing water from entering at the interface between the socket connector 101 and the battery pack housing 100. Simultaneously, the interface sealing ring 17 seals the shielding perforations of the socket housing 11. The signal terminal 14 and power terminal 13 also form seals with the socket housing 11, achieving a single-unit sealing function for the socket connector 101, preventing external water from entering the battery pack housing 100 through the socket connector 101.

[0057] The interface sealing ring 17 has four annular surrounding portions 171, each corresponding to a shielding protrusion 153. The shielding protrusion 153 and the shielding contact portion 154 are located within the space enclosed by the corresponding surrounding portions 171. Each surrounding portion 171 includes an inner portion near the center line of the interface sealing ring 17 and an outer portion relatively far from the center line. The space in the sealing groove for mounting the inner portion of the surrounding portion 171 communicates with the corresponding shielding perforation, allowing the inner surface of the shielding protrusion 153 to contact the inner portion of the surrounding portion 171. The outwardly turned shielding contact portion 154 faces the outer portion of the surrounding portion 171 and abuts against the surface of the mounting surface 18 located between the inner and outer portions of the surrounding portion 171. The surrounding portion 171 encircles the periphery of the shielding perforation to cooperate with the battery pack housing 100 in forming a seal at the point where the shielding protrusion 153 passes through the socket housing 11. This interface sealing ring 17 can be integrally formed, saving manufacturing costs. In other embodiments, a seal can also be formed by separate inner and outer sealing rings, with the inner and outer sealing rings located on the inner and outer sides of the shielding penetration part, respectively, to ensure that water does not enter.
