[0002] This application claims priority to Chinese patent application No. 202311093904.9 filed on August 29, 2023, and cites the contents disclosed in the above patent application as part of this application. Technical Field

[0003] The present application relates to the technical field of connectors, and more particularly, to a sliding cover type connector. Background Art

[0004] Some types of high-voltage automotive connectors currently used in electric vehicles (EVs) and hybrid electric vehicles (HEVs) are made of aluminum for their housings, particularly aluminum rod wiring harness connectors. Aluminum-shell connectors have a housing and a cover. The housing has an access port for operating the terminal connections and observing the connection status. The cover is used to close or open the access port. The cover and housing are typically connected by a rotating shaft and bolts. Specifically, one side of the cover is pivotally connected to the corresponding portion of the housing via the rotating shaft, allowing the cover to be flipped open and closed to open or close the access port. Bolts secure the cover to the housing to prevent it from opening unexpectedly. This structure results in the following: opening or closing the cover requires a certain amount of space when flipping the cover, requiring a large amount of space for operation; and the bolts need to be tightened or removed after closing or before opening the cover. This operation requires tools and cannot be performed manually without them, resulting in poor operational convenience.

[0005] Summary of the Invention

[0006] One purpose of the present application is to provide a sliding cover type connector to solve the problem of large operating space requirement and poor operating convenience caused by the upper cover of the existing connector being rotatably connected to the shell and fixed with bolts.

[0008] Optionally, a locking groove is provided on the inner side of the sliding part, and a third sliding rail is provided on the shell on one side of the second sliding rail. The locking member is slidably assembled on the third sliding rail and can at least partially enter the locking groove along the sliding direction of the third sliding rail to prevent the sliding part from sliding along the second sliding rail to the first sliding rail.

[0009] Optionally, the locking member includes a main body and a latch arranged on the main body and cooperating with the lock slot. The main body is slidably assembled on the third slide rail and can drive the latch to at least partially enter the lock slot during the sliding process.

[0010] Optionally, an elastic hook is further provided on the main body of the locking member, and the third slide rail is provided with at least two limiting grooves in its setting direction. The elastic hook is sequentially hooked with the two limiting grooves so that the latch is correspondingly maintained in the unlocked position not entering the lock slot and the locked position entering the lock slot.

[0011] Optionally, the main body is further provided with an elastic arm with a free end biased toward the shell, and the shell is provided with a pre-installed stop block that cooperates with the free end of the elastic arm to prevent the locking member from withdrawing from the third slide rail.

[0012] Optionally, a slider is provided on the side of the sliding portion facing the shell, the slider is slidably engaged with the first slide rail, and a sliding gap for accommodating the locking groove is provided between the slider and the cover body.

[0013] Optionally, the first slide rail is a plate-shaped structure, the first slide rail is located in a sliding gap between the slider and the cover body, and the slider and the side of the first slide rail facing away from the cover body are slidably engaged.

[0014] Optionally, an elastic member is provided on the shell, and the elastic member pushes the cover body toward the side of the shell, so that there is a floating gap between the cover body and the shell and the slider maintains a sliding fit with the first slide rail.

[0015] Optionally, the elastic member includes a spring plate with one end connected to the shell and the other end facing the operation port, and the spring plate is provided with a pushing portion for pushing the cover body.

[0016] Optionally, the middle portion of the elastic sheet protrudes toward the cover body to form the pushing portion, and one end of the elastic sheet facing the operating port is bent toward the shell to form a guiding slope for guiding the cover body to move toward the pushing portion.

[0017] Optionally, the second slide rail includes two guide blocks arranged side by side on the shell, and the sliding block slides in the space between the two guide blocks to achieve sliding cooperation between the sliding part and the second slide rail.

[0018] Optionally, at least two sliders are arranged on the sliding portion at intervals, and after the cover is arranged on the outside of the operating port, the portion of the locking member entering the lock groove is locked correspondingly to at least one slider.

[0019] Optionally, the cover body is provided with a convex edge structure on the side facing the shell, and a sealing ring is installed on the periphery of the convex edge structure. After the cover body is arranged on the outside of the operating port, the sealing ring is inserted into and matched with the inner wall of the operating port to achieve sealing between the cover body and the operating port.

[0020] The above-mentioned scheme is further optimized. When there are two sliders, a first auxiliary block installed on the shell is provided at the intersection of the second slide rail and the first slide rail. The first auxiliary block is located between the two guide blocks and extends along the sliding direction of the first slide rail, and there is an avoidance gap between the two ends of the first auxiliary block and the corresponding guide blocks for the corresponding slider to pass through. When the sliding part slides to the intersection of the first slide rail and the second slide rail, the first auxiliary block guides the slider that first approaches the second slide rail to continue sliding along the sliding direction of the first slide rail to prevent it from entering the second slide rail prematurely. When each slider corresponds to the second slide rail and can enter the second slide rail, the two sliders slide into the second slide rail from the corresponding avoidance gaps respectively.

[0021] The above-mentioned scheme is further optimized, and a second auxiliary block is provided at the end of the first auxiliary block facing away from the locking member, which enters the second slide rail along the sliding direction of the second slide rail. After both sliders enter the avoidance gap, the second auxiliary block and the adjacent guide block jointly guide the corresponding slider to slide stably along the second slide rail.

[0022] This application has the following beneficial effects:

[0023] 1. The present application adopts a sliding cover structure to seal the operating port. The sliding cover can slide on the shell, taking up less space, thus avoiding the problem of the traditional flip cover structure taking up a large space.

[0024] 2. The sliding cover of the present application is guided by a combination of a first guide rail and a second guide rail. When sliding from the first guide rail to the second guide rail, the sliding track changes, making it adaptable to various housing structures and flexible in application. For example, in situations where different housing shapes, different operating port positions, different housing surface structures, or the side of the cover body facing the operating port requires a blocking structure adapted to the operating port, by pre-reasonably and adaptively adjusting the positions of the various rails on the housing, a sliding track adapted to the housing or operating port can be formed, and an appropriate spacing can be established between the cover body and the housing or operating port. This allows the sliding cover to approach and close the operating port with a more suitable non-unidirectional track in more demanding installation or operating spaces, or allows the sliding cover to avoid protruding structures on the housing surface to improve its adaptability, or makes operation or assembly of the sliding cover more convenient and efficient.

[0025] 3. The locking member of the present application is arranged on the shell and cooperates with the sliding part of the sliding cover. After the sliding part is in place, the locking member can be manually operated to manually lock the sliding part, or the locking member can automatically lock the sliding part by itself. Therefore, there is no need to use auxiliary tools separately, avoiding the problem of relying on auxiliary tools for disassembly and assembly of bolts in traditional flip-cover structures, thereby essentially improving the convenience of operation.

[0036] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0040] As shown in Figures 1 to 7, a sliding cover type connector includes a shell 2 with an operating port 24 on the top and a sliding cover 1 slidably arranged at the operating port 24. The sliding cover 1 includes a cover body 11 and sliding portions 12 arranged on both sides of the sliding direction of the cover body 11. A first slide rail 21 and a second slide rail 22 that slide with the corresponding sliding portion 12 are provided on the corresponding sides of the shell 2, and the sliding track extension lines of the sliding portion 12 on the first slide rail 21 and the second slide rail 22 intersect. The sliding portion 12 can slide from the first slide rail 21 into the second slide rail 22 and when sliding to a predetermined position along the second slide rail 22, the cover body 11 of the sliding cover 1 is covered on the outside of the operating port 24. A locking member 3 that can lock the sliding portion 12 that slides to a predetermined position is provided on the shell 2.

[0041] The sliding cover type connector of the embodiment of the present application adopts a sliding cover structure to close the operation port 24. The sliding cover 1 can slide on the housing 2, taking up less space, thus avoiding the problem of the traditional flip cover structure taking up a large space.

[0042] It is understandable that regarding the intersection of the extended lines of the sliding tracks of the first and second slide rails, in some embodiments, while ensuring that the sliding portion can slide from the first slide rail to the second slide rail, the first slide rail can be arranged in a non-direct connection with the second slide rail. In other embodiments, the above scheme may have special circumstances, that is, the first slide rail and the second slide rail can be directly connected end to end and are not in the same straight line. At this time, it belongs to the special state of the intersection of the extended lines of the sliding tracks, that is, the extended lines of the sliding tracks intersect at the corresponding extended starting positions. In addition, it should be understood and clarified that no matter which of the above circumstances, the first slide rail and the second slide rail are not in the same straight line or are not parallel to each other, and the angle between the extended lines of the sliding tracks of the first slide rail and the second slide rail can be adjusted according to the actual shell conditions, such as forming a right angle or obtuse angle relative to the first slide rail.

[0043] The sliding cover 1 of the sliding cover connector of the embodiment of the present application is guided by a combination of a first guide rail and a second guide rail. When sliding from the first guide rail 21 to the second guide rail 22, the sliding track changes, and the sliding cover can be adapted to various structural types of housings 2, with high adaptability and flexible application. For example, in situations where different housing shapes, different operating port positions, different housing surface structures, or the side of the cover body facing the operating port requires a blocking structure adapted to the operating port, by pre-reasonably and adaptively adjusting the positions of the first and second guide rails on the housing, a sliding track adapted to the housing or the operating port can be formed, and a suitable spacing can be provided between the cover body and the housing or the operating port. This allows the sliding cover to approach and close the operating port with a more suitable non-unidirectional track in more stringent installation or operating spaces, or allows the sliding cover to avoid structures on the housing surface that may interfere with sliding, thereby improving the sliding cover's applicability, or making the operation or disassembly of the sliding cover more convenient and efficient.

[0044] It can be understood that, with respect to the locking member provided on the shell, in some embodiments, the locking member may adopt a sliding structure, so that when the locking member is directly slid by hand, the sliding portion in the above-mentioned predetermined position can be manually locked, and when the lock is released, the locking member can be directly slid in the opposite direction by hand; in other embodiments, the locking member 3 may also adopt an elastic hook structure, so that when the sliding portion slides to the above-mentioned predetermined position, the elastic hook can be automatically hooked with the corresponding preset matching structure of the sliding portion, such as a slot, to automatically lock, and when the lock is released, the elastic hook can be directly moved by hand or a large pulling force can be applied to the sliding cover to disengage the elastic hook from the matching structure; in more embodiments, the locking member may also adopt other manual locking structures or automatic locking structures that can be achieved without tools, such as a friction block that uses friction generated by interference fit with the sliding portion to lock, other types of snap structures that match the sliding portion, and the like.

[0045] The locking member 3 of the sliding cover connector of the embodiment of the present application is arranged on the shell 2, and can be directly operated by hand or without operation to achieve the locking purpose, so there is no need to use auxiliary tools separately, avoiding the problem of relying on auxiliary tools for disassembling and assembling bolts in the traditional flip-cover structure, and the convenience of operation is essentially improved. When the locking member 3 is arranged on the shell 2, it reduces or avoids being lost due to detachment from the shell 2, and the operational reliability is also essentially improved.

[0046] In this embodiment, the first slide rail 21 and the second slide rail 22 are positioned at a right angle, and the extended lines of their sliding tracks intersect at corresponding extended starting positions.

[0047] Furthermore, in order to obtain a more stable and reliable locking effect, in this embodiment, a locking groove is provided on the inner side of the sliding portion 12, and a third slide rail 23 is provided on the shell 2 on one side of the second slide rail 22. The locking member 3 is slidably assembled on the third slide rail 23 and can at least partially enter the locking groove along the sliding direction of the third slide rail 23 to prevent the sliding portion 12 from sliding along the second slide rail 22 to the first slide rail 21.

[0048] More specifically, to facilitate actuation and locking, in this embodiment, the locking member 3 includes a main body 31 and a latch 32 disposed on the main body 31 and engaging with a locking slot. The main body 31 is slidably mounted on the third rail 23, and during the sliding process, the latch 32 is driven at least partially into the locking slot. The third rail 23 has two parallel slideways, with slide bars 311 slidably mounted on either side of the main body 31. The slideway proximal to the first rail 21 extends to the second rail 22, while the slideway distal to the first rail 21 continues to extend, positioning the second rail 22 between it and the first rail 21.

[0049] More specifically, in order to facilitate the control of the sliding position of the locking member 3 and obtain the feedback of the positioning, in this embodiment, an elastic hook 33 is also provided on the main body 31 of the locking member 3, and the third slide rail 23 is provided with two limiting grooves 231 in its setting direction. The elastic hook 33 is sequentially hooked with the two limiting grooves 231 to keep the latch 32 in the unlocking position that has not entered the lock slot and the locking position that has entered the lock slot respectively.

[0050] In detail, in this embodiment, the elastic hook 33 and the latch 32 are arranged side by side in the same direction and are both located between the two slides. Compared with the latch 32, the elastic hook 33 is farther away from the first slide rail 21 and extends longer. The longer length of the elastic hook 33 can have better elasticity to ensure smooth hooking and movement. Two limiting grooves 231 are provided on the slide of the third slide rail 23 adjacent to the elastic hook 33. When the latch 32 is in the locked position, there is a gap between the elastic hook 33 and the end of the sliding part 12 away from the cover body 11 to prevent the elastic hook 33 from blocking the movement of the sliding part 12.

[0051] In other embodiments, as for the number of limiting grooves, more limiting grooves can be added while ensuring that the latch and the locking member have the above-mentioned unlocking position and locking position. For example, one or more grooves can be added between the limiting groove of the unlocking position and the limiting groove of the locking position so that the latch and the locking member have an intermediate position between the unlocking position and the locking position. The specific number is based on actual needs.

[0052] More specifically, in order to prevent the locking member 3 from exiting the third slide rail 23, in this embodiment, the main body 31 is further provided with an elastic arm 34 with a free end deflected toward the housing 2, and the housing 2 is provided with a pre-installed stop block 232 that cooperates with the free end of the elastic arm 34 to prevent the locking member 3 from exiting the third slide rail 23. When the slide bar 311 of the main body 31 is installed on the third slide rail 23, as the slide bar 311 slides on the third slide rail 23 toward the second slide rail 22, the elastic arm 34 The free end of the elastic arm 34 interferes with the path of the pre-installed anti-retraction protrusion 232 and undergoes elastic deformation until the free end of the elastic arm 34 passes over the pre-installed anti-retraction protrusion 232, and the free end of the elastic arm 34 recovers and cooperates with the pre-installed anti-retraction protrusion 232. At this time, the main body 31 is completely and correctly assembled on the third slide rail 23, and under the anti-retraction cooperation between the elastic arm 34 and the pre-installed anti-retraction protrusion 232, it cannot withdraw from the third slide rail 23, thereby achieving the purpose of preventing the locking member 3 from withdrawing from the third slide rail 23.

[0053] Furthermore, to achieve sliding engagement between the sliding portion 12 and the first slide rail 21 and simultaneously form a locking groove, simplify the structure, and facilitate installation and processing, in this embodiment, a slider 13 is provided on the side of the sliding portion 12 facing the housing 2. The slider 13 slides in engagement with the first slide rail 21, and a sliding gap is defined between the slider 13 and the cover 11 to accommodate the locking groove. Specifically, the portion of the sliding gap adjacent to the slider 13 constitutes the locking groove. When the locking member 3 is locked with the sliding portion 12, the portion of the locking member 3 that enters the locking groove engages with the slider 13 to achieve a locking effect. In this embodiment, the aforementioned latch 32 enters the locking groove and engages with the corresponding slider 13 to achieve locking of the sliding portion 12.

[0054] In other embodiments, as for the lock slot, a slot adapted to the latch may be specially provided on the inner side of the sliding portion and used as the lock slot, into which the latch is inserted when locking to achieve the same locking effect.

[0055] More specifically, in order to allow a floating gap between the cover body 11 and the shell body 2 to avoid the protruding structure on the shell body 2, or to allow a floating gap between the cover body 11 and the shell body 2 to accommodate the closed structure when a closed structure that is plugged in and out of the operating port 24 is preset on the cover body 11, in this embodiment, the first slide rail 21 is a plate-like structure, and the first slide rail 21 is located in the sliding gap between the slider 13 and the cover body 11, and the slider 13 slides with the side of the first slide rail 21 away from the cover body 11. An elastic member is provided on the shell body 2, and the elastic member pushes the cover body 11 toward the side of the shell body 2, so that the above-mentioned floating gap is provided between the cover body 11 and the shell body 2 and the slider 13 maintains a sliding fit with the first slide rail 21.

[0056] In other embodiments, other retaining methods may be used instead of elastic members to maintain the sliding fit between the slider and the side of the first slide rail facing away from the cover body. For example, the first slide rail may be made of iron, and a magnet may be embedded in the slider. The magnet engages with the side of the first slide rail facing away from the cover body, thereby achieving the sliding fit between the slider and the side of the first slide rail facing away from the cover body and maintaining the above-mentioned floating gap normally.

[0057] More specifically, in this embodiment, the elastic member includes a spring piece 5 having one end connected to the shell 2 and the other end facing the operating port 24, and the spring piece 5 is provided with a pushing portion 51 for pushing the cover body 11; in detail, the middle portion of the spring piece 5 protrudes toward the cover body 11 to form the pushing portion 51, so that the sliding cover 1 can smoothly push the cover body 11 after returning from the second slide rail 22 to the first slide rail 21. As an added structural improvement, the end of the spring piece 5 facing the operating port 24 is deflected toward the shell 2 to form a guiding inclined surface 52 for guiding the cover body 11 to move toward the pushing portion 51; the end of the spring piece 5 connected to the shell 2 is provided with a through hole, and a fixing bolt 6 is passed through the through hole, and the connection between the spring piece 5 and the shell 2 is achieved by the fixing bolt 6.

[0058] In other embodiments, the elastic member may also be a block structure made of elastic rubber, sponge or other similar materials. The block structure may also be provided with a portion for pushing the cover body and a portion for guiding the movement of the cover body.

[0059] More specifically, in order to adapt to the movement of the slider 13, in this embodiment, the second slide rail 22 includes two guide blocks 221 arranged side by side on the shell 2, and the slider 13 slides in the space between the two guide blocks 221 to achieve sliding cooperation between the sliding part 12 and the second slide rail 22; in addition, in this embodiment, the guide block 221 adjacent to the third slide rail 23 intersects with the first slide rail 21 at one end toward the first slide rail 21, so as to stop the slider 13 when it slides along the first slide rail 21 to a position where it can slide into the second slide rail 22, preventing the slider 13 from sliding excessively along the first slide rail 21 and being unable to slide into the second slide rail 22, and the end of the guide block 221 away from the first slide rail 21 intersects with the slideway of the third slide rail 23 close to the first slide rail 21, and the other guide block 221 has a gap between its end toward the first slide rail 21 and the first slide rail 21 for the slider 13 to pass through, and the other end extends to a position corresponding to the part of the locking member 3 entering the lock groove, i.e., the latch 32.

[0060] More specifically, in order to make the sliding cooperation between the sliding part 12 and the first slide rail 21 and the second slide rail 22 more stable, in this embodiment, two sliders 13 are arranged on the sliding part 12 at intervals. After the cover body 11 is covered on the outside of the operating port 24, the part of the locking member 3 that enters the lock groove, that is, the latch 32, is locked with the adjacent slider 13.

[0061] In other embodiments, there may be three or more sliders, and the portion of the locking member that enters the locking slot may be locked correspondingly with at least one slider.

[0062] In this embodiment, in order to enable the two sliders 13 to slide smoothly into the second slide rail 22, a first auxiliary block 222 installed on the shell 2 is provided at the intersection of the second slide rail 22 and the first slide rail 21. The first auxiliary block 222 is located between the two guide blocks 221 and extends along the sliding direction of the first slide rail 21, and there is an avoidance gap between the two ends of the first auxiliary block 222 and the corresponding guide blocks 221 for the corresponding sliders 13 to pass through. When the sliding part 12 slides to the intersection of the first slide rail 21 and the second slide rail 22, the first auxiliary block 222 guides the slider 13 that first approaches the second slide rail 22 to continue sliding along the sliding direction of the first slide rail 21 to prevent it from entering the second slide rail 22 prematurely. When the two sliders 13 both correspond to the second slide rail 22 and can enter the second slide rail 22, the two sliders 13 slide into the second slide rail 22 from the corresponding avoidance gaps respectively.

[0063] In this embodiment, in order to make the sliding of the sliding part 12 in the second slide rail 22 more stable, the end of the first auxiliary block 222 away from the locking member 3 is provided with a second auxiliary block 223 that enters the second slide rail 22 along the sliding direction of the second slide rail 22. The second auxiliary block 223 is the same length as the adjacent guide block 221. After both sliders 13 enter the above-mentioned avoidance gap, the second auxiliary block 223 and the adjacent guide block 221 jointly guide the slider 13 away from the locking member 3 to slide stably along the second slide rail 22.

[0064] Furthermore, in order to improve the sealing ability of the cover body 11 when closing the operating port 24, in this embodiment, the cover body 11 is provided with an annular flange structure 14 on the side facing the shell 2, which is plugged into and adapted to the operating port 24. A sealing ring 4 is installed on the outer periphery of the flange structure 14. The combination of the flange structure 14 and the sealing ring 4 is the aforementioned closed structure that is plugged in and out with the operating port 24. After the cover body 11 is covered on the outside of the operating port 24, the sealing ring 4 is plugged into and adapted to the inner side wall of the operating port 24 to achieve sealing between the cover body 11 and the operating port 24. The end of the flange structure 14 in this embodiment that faces away from the cover body 11 is also provided with a flange structure to prevent the sealing ring 4 from falling off.

[0065] In this embodiment, during the process of the sliding cover 1 returning to its initial position on the first slide rail 21, the aforementioned guiding inclined surface 52 and the convex edge structure 14 have a direct guiding relationship; in addition, after the sliding cover 1 returns to its initial position on the first slide rail 21, the pushing portion 51 of the spring piece 5 is squeezed and deformed to pass over the convex edge structure 14 and is located inside the convex edge structure 14. When the sliding cover 1 slides toward the operating port 24 due to an unexpected force, the pushing portion 51 needs to pass over the convex edge structure 14 again to come out of the convex edge structure 14. This process can, to a certain extent, prevent the sliding cover 1 from sliding toward the operating port 24 unexpectedly.

[0066] In this embodiment, the first slide rail 21, the second slide rail 22, the third slide rail 23, the pre-installed stop block 232, the first auxiliary block 222, and the second auxiliary block 223 are all integrally formed with the housing 2, and the locking member 3 and the sliding cover 1 are also integrally formed.

[0067] The specific operation process of this slide-type connector is as follows.

[0068] S1, initial position:

[0069] Install the sliding cover 1 on the first sliding rail 21 from the end of the first sliding rail 21 away from the operation port 24. At this time, the sliding cover 1 is in the initial position, the pushing portion 51 of the spring 5 pushes the cover body 11, and the slider 13 slides and cooperates with the side of the first sliding rail 21 away from the cover body 11; install the locking member 3 on the third sliding rail 23 and put the latch 32 in the unlocked position.

[0070] S2, driving the slide cover 1 to close the operating port 24:

[0071] The sliding cover 1 is driven to move along the first sliding rail 21 toward the operating opening 24. After the slider 13 of the sliding part 12 slides from the first sliding rail 21 to the second sliding rail 22, the sliding cover 1 is driven to slide along the second sliding rail 22 until the convex structure 14 and the sealing ring 4 are inserted into the operating opening 24 and the cover body 11 is completely covered on the outside of the operating opening 24. The sliding part 12 reaches the predetermined position and the sliding cover 1 completes the sealing of the operating opening 24.
