[0001] This utility model relates to the field of electrical connection technology, and in particular to a connector and a vehicle. Background Technology

[0002] Connectors include high-voltage connectors and low-voltage connectors. Both high-voltage and low-voltage connectors include male and female terminals that interlock. Connectors are an important component of automotive electrical systems. They are responsible for the key tasks of transmitting electrical signals and supplying power between different circuits. High-voltage connectors in vehicles are mainly used in DC, water-cooled PTC chargers, air-cooled PTC chargers, DC charging ports, power motors, high-voltage wiring harnesses, switches, inverters, power batteries, and other systems.

[0003] To prevent accidental separation of the two connecting parts, a movable locking part is provided on one of the connecting parts, with the unlocking end of the locking part exposed for operator unlocking. A locking engagement part is provided on the other connecting part. When the two connecting parts are inserted into place, one end of the locking part engages with the locking engagement part, locking the two connecting parts together and preventing separation. When external force is applied to the unlocking end of the locking part, that end separates from the locking engagement part, thus unlocking the connector. Because the unlocking end of the locking part is exposed, there is a risk that misoperation during use may cause displacement during unlocking, thereby affecting the stability and safety of the vehicle's electrical connections. Utility Model Content

[0004] The purpose of this invention is to provide a connector that solves the problem of the risk of accidental locking due to the exposed unlocking end of the locking part, thereby improving the stability and security of the electrical connection.

[0005] To achieve the objective of this utility model, the following technical solution is adopted:

[0006] According to one aspect of the present invention, a connector is provided, including a first sheath, a second sheath inserted into the first sheath, and a protective member. The first sheath has a movable locking portion, and the second sheath has a locking mating portion. When the locking portion locks with the locking mating portion, one end of the locking portion abuts against one end of the locking mating portion along the disassembly direction of the second sheath. The protective member is slidably mounted on the first sheath, and the projection of the protective member overlaps with the projection of the locking portion. In a first position, the protective member abuts against the first sheath. In a second position, there is an movable gap between the protective member and the first sheath. When a force is applied to the protective member, the protective member causes the locking portion to separate from the locking mating portion.

[0007] According to one embodiment of the present invention, a guide portion is provided on one side of the first sheath, and the guide portion has a guide cavity that extends through both ends. One end of the locking portion along the disassembly direction of the second sheath and one end of the protective member along the disassembly direction of the second sheath are both located inside the guide cavity. One end of the locking portion along the installation direction of the second sheath and one end of the protective member along the installation direction of the second sheath are both located outside the guide cavity, and the protective member slides along the guide cavity.

[0008] According to one embodiment of the present invention, the first wall surface of the first sheath has a first protrusion, and one side of the protective member has a second protrusion. When the protective member is in the first position, the second protrusion abuts against the first protrusion. When the protective member is in the second position, there is a gap between the second protrusion and the first protrusion, and there is an movable gap between the second protrusion and the first wall surface of the first sheath for unlocking.

[0009] According to one embodiment of the present invention, the second protrusion has a relief cavity, and when the protective member is in the first position, one end of the locking part located outside the guide cavity is located inside the relief cavity.

[0010] According to one embodiment of the present invention, the protective member has a third protrusion at one end along the disassembly direction of the second sheath, and when the protective member is in the first position, the third protrusion abuts against the locking engagement part at one end along the disassembly direction of the second sheath.

[0011] According to one embodiment of the present invention, the protective member has a fourth protrusion at one end outside the guide cavity, and the fourth protrusion is configured as a force application point for external force to drive the protective member to slide.

[0012] According to one embodiment of the present invention, the protective member is an elastic member, and there is a gap between one end of the protective member along the disassembly direction of the second sheath and one side wall of the guide cavity for the movement of the protective member.

[0013] According to one embodiment of the present invention, the first sheath has an annular insertion cavity, the second sheath has an annular wall, the annular wall is inserted into the annular insertion cavity, the guide cavity is connected to the annular insertion cavity, and the locking engagement part is located on the outer wall surface of the annular wall.

[0014] According to one embodiment of the present invention, the locking engagement part includes a fifth protrusion and a guide slope. The fifth protrusion is located on the outer wall surface of the annular wall, and the guide slope is located on the side of the fifth protrusion facing the insertion direction of the second sheath. The guide slope is inclined from the free end of the fifth protrusion toward the outer wall surface of the annular wall.

[0015] This utility model also discloses a vehicle that includes the aforementioned connector.

[0016] One embodiment of this utility model has the following advantages or beneficial effects:

[0017] The connector of this utility model includes a first sheath, a second sheath that inserts into the first sheath, and a protective member. The first sheath has a movable locking part, and the second sheath has a locking mating part. When the locking part and the locking mating part are locked, one end of the locking part abuts against one end of the locking mating part along the disassembly direction of the second sheath. The protective member is slidably mounted on the first sheath, and the projection of the protective member overlaps with the projection of the locking part, thus isolating the locking part from the outside. In the first position, the protective member abuts against the first sheath, and there is no space between the protective member and the first sheath, preventing the protective member from moving in the unlocking direction C, thereby avoiding accidental contact with the locking part and mis-locking. In the second position, there is a gap between the protective member and the first sheath. When a force is applied to the protective member in the unlocking direction C, the protective member causes one end of the locking part to lift up and separate from the locking mating part, allowing the second sheath to be pulled out in the disassembly direction B.

[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0025] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended meaning of inclusion and that other elements / components / etc. may exist in addition to the listed elements / components / etc.

[0026] like Figure 1-3 As shown, a connector according to an embodiment of the present invention includes a first sheath 1, a second sheath 2 that is inserted into the first sheath 1, and a protective member 3. Figure 2 The direction A shown is the insertion direction of the second sheath 2, the direction B is the disassembly direction of the second sheath 2, and the direction C is the unlocking direction of the locking part 11.

[0027] The first sheath 1 has a movable locking part 11. For example, the locking part 11 is an elastic element. A connecting arm 111 extends from one side of the locking part 11. One end of the connecting arm 111 is fixed to one side of the first sheath 1. There is a movable gap between the locking part 11 and one side of the first sheath 1. When the locking part 11 is pressed down at one end along the insertion direction of the second sheath 2, the locking part 11 tilts up at one end along the disassembly direction of the second sheath 2. When the downward pressure is released, the locking part 11 automatically resets.

[0028] The second sheath 2 has a locking engagement part 21. When the locking part 11 locks with the locking engagement part 21, one end of the locking part 11 along the disassembly direction of the second sheath 2 abuts against one side of the locking engagement part 21 along the disassembly direction of the second sheath 2, thereby locking the second sheath 2 with the first sheath 1.

[0029] The protective component 3 is slidably mounted on the first sheath 1, and the projection of the protective component 3 overlaps with the projection of the locking part 11, such as... Figure 2 As shown, when the protective member 3 is in the first position, the protective member 3 abuts against the first protective sleeve 1, and there is no space for movement between the protective member 3 and the first protective sleeve 1, so that the protective member 3 cannot move in the unlocking direction C, thereby avoiding accidental locking when the other end of the locking part 11 is accidentally touched.

[0030] like Figure 3 As shown, when the protective member 3 slides from the first position to the second position, there is an active gap between the protective member 3 and the first sheath 1. When a force is applied to the protective member 3 in the unlocking direction C, the protective member 3 drives the locking part 11 to move in the direction C along the insertion direction of the second sheath 2, so that the locking part 11 is tilted up and separated from the locking mating part 21 along the disassembly direction of the second sheath 2, thereby allowing the second sheath 2 to be pulled out in the disassembly direction B.

[0031] like Figure 1-3As shown, in a preferred embodiment of the present invention, a guide portion 12 is provided on one side of the first sheath 1. The guide portion 12 has a guide cavity 121 that extends through both ends. One end of the locking portion 11 along the disassembly direction of the second sheath 2 and one end of the protective member 3 along the disassembly direction of the second sheath 2 are both located inside the guide cavity 121. One end of the locking portion 11 along the installation direction of the second sheath 2 and one end of the protective member 3 along the installation direction of the second sheath 2 are both located outside the guide cavity 121. The protective member 3 slides along the guide cavity 121.

[0032] During the insertion process between the second sheath 2 and the first sheath 1, the locking engagement part 21 extends from one end of the guide part 12 along the disassembly direction of the second sheath 2 into the guide cavity 121.

[0033] When the second sheath 2 is inserted into the first sheath 1, one end of the locking part 11 along the disassembly direction of the second sheath 2 abuts against the side of the locking mating part 21 facing the disassembly direction of the second sheath 2, thereby limiting the second sheath 2.

[0034] like Figure 2-3 As shown, in a preferred embodiment of the present invention, the first wall surface of the first sheath 1 has a first protrusion 13, and the end of the protective member 3 along the insertion direction of the second sheath 2 has a second protrusion 31.

[0035] like Figure 2 As shown, when the protective member 3 is in the first position, the second protrusion 31 abuts against the first protrusion 13, preventing the protective member 3 from moving in the unlocking direction C. At the same time, the end of the protective member 3 located outside the guide cavity 121 isolates the end of the locking part 11 located outside the guide cavity 121 from the outside, preventing fingers or other parts from contacting the locking part 11 to avoid accidental locking, thereby protecting the locking part 11.

[0036] like Figure 3 As shown, when the protective member 3 is in the second position, the second protrusion 31 is misaligned with the first protrusion 13 and has a gap. There is an active gap between the second protrusion 31 and the first wall surface of the first sheath 1 for unlocking. When pressure is applied to one end of the protective member 3 in the insertion direction of the second sheath 2 in the direction of C, the protective member 3 drives the locking part 11 to move in the direction of C in the insertion direction of the second sheath 2, so that the end of the locking part 11 located in the guide cavity 121 is raised, thereby separating from the locking engagement part 21 and releasing the locking part 11 from locking the second sheath 2.

[0037] like Figure 2-3 As shown, in a preferred embodiment of this utility model, the second protrusion 31 has a clearance cavity 311. Figure 2As shown, when the protective member 3 is in the first position, the end of the locking part 11 located outside the guide cavity 121 is located inside the relief cavity 311, which avoids the locking part 11 from directly contacting the second protrusion 31 and causing the movement of the protective member 3 to be limited, thus realizing the free movement of the protective member 3 between the first position and the second position.

[0038] like Figure 3 As shown, when the protective member 3 is in the second position, one end of the locking part 11 located outside the guide cavity 121 is located at the edge of the relief cavity 311, and there is a gap between the second protrusion 31 and the first protrusion 13, so that there is an active gap for unlocking between the second protrusion 31 and the first wall surface of the first sheath 1.

[0039] like Figure 2-3 As shown, in a preferred embodiment of the present invention, the protective member 3 has a third protrusion 32 at one end along the disassembly direction of the second sheath 2. When the protective member 3 is in the first position, the third protrusion 32 abuts against the locking engagement part 21 at one end along the disassembly direction of the second sheath 2, preventing the protective member 3 from accidentally sliding from the first position to the second position and causing the protection to fail. Only when sufficient thrust is applied to the protective member 3 in the installation direction of the second sheath 2 can the third protrusion 32 separate from the locking part 11 at one end in the disassembly direction of the second sheath 2.

[0040] like Figure 2-3 As shown, in a preferred embodiment of this utility model, there is an movable gap between the end of the protective member 3 facing the disassembly direction of the second sheath 2 and one side wall 1211 of the guide cavity 121. The protective member 3 is an elastic member. When the protective member 3 is pushed from the first position to the second position, the third protrusion 32 is pushed up by the end of the locking part 11 facing the disassembly direction of the second sheath 2. When the third protrusion 32 passes the end of the locking part 11 facing the disassembly direction of the second sheath 2, the end of the protective member 3 facing the disassembly direction of the second sheath 2 is reset, so that the sliding of the protective member 3 has a certain resistance to jamming, and prevents the protective member 3 from sliding freely when it is not subjected to external force.

[0041] The main body of the protective component 3 is located between one side wall 1211 and the locking part 11. The cavity wall of the guide cavity 121 and the locking part 11 together guide the sliding of the protective component 3.

[0042] like Figure 2-3 As shown, in a preferred embodiment of the present invention, the protective member 3 has a fourth protrusion 33 at one end along the insertion direction of the second sheath 2. The protrusion direction of the fourth protrusion 33 is opposite to the protrusion direction of the second protrusion 31. The fourth protrusion 33 is configured as a force application point for pushing the protective member 3 to slide, so as to facilitate pushing the protective member 3 to move between the first position and the second position.

[0043] like Figure 2-3As shown, in a preferred embodiment of this utility model, the first sheath 1 has an annular insertion cavity 14, the second sheath 2 has an annular wall 22, the guide cavity 121 communicates with the annular insertion cavity 14, and the locking fitting part 21 is located on the outer wall surface of the annular wall 22. When the annular wall 22 is inserted into the annular insertion cavity 14, one end of the locking part 11 along the disassembly direction of the second sheath 2 abuts against one end of the locking fitting part 21 along the disassembly direction of the second sheath 2, thereby locking the second sheath 2. At the same time, it seals the cavity of the first sheath 1 and the cavity of the second sheath 2, preventing dust or water from entering the first sheath 1 or the second sheath 2.

[0044] like Figure 2-3 As shown, in a preferred embodiment of the present invention, the locking engagement part 21 includes a fifth protrusion 211 and a guide slope 212. The fifth protrusion 211 is fixed to the outer wall surface of the annular wall 22, and the guide slope 212 is fixed to the side of the fifth protrusion 211 facing the insertion direction of the second sheath 2. The guide slope 212 is inclined from the free end of the fifth protrusion 211 toward the outer wall surface of the annular wall 22.

[0045] During the insertion of the annular wall 22 into the annular insertion cavity 14, one end of the locking part 11 along the disassembly direction of the second sheath 2 is lifted by the guide slope 212 to avoid the fifth protrusion 211; when the annular wall 22 and the annular insertion cavity 14 are inserted into place, one end of the locking part 11 along the disassembly direction of the second sheath 2 is reset and abuts against the side wall of the fifth protrusion 211 facing the disassembly direction of the second sheath 2, thereby limiting the second sheath 2.

[0046] As the protective member 3 slides from the second position to the first position, the third protrusion 32 is pushed up along the guide slope 212, so that the third protrusion 32 passes through the fifth protrusion 211 and the locking part 11 at one end along the disassembly direction of the second sleeve 2. When the protective member 3 slides to the first position, the third protrusion 32 is reset and abuts against the locking part 11 at one end along the disassembly direction of the second sleeve 2.

[0047] When the first sheath 1 is the sheath for the male end connection, the second sheath 2 is the sheath for the female end connection; when the first sheath 1 is the sheath for the female end connection, the second sheath 2 is the sheath for the male end connection. Those skilled in the art can select the installation position of the protective component 3 according to actual needs.

[0048] like Figure 2-3 As shown, in a preferred embodiment of this utility model, the locking part 11 has a sixth protrusion 112 at one end along the disassembly direction of the second sheath 2. When locked, the sixth protrusion 112 abuts against the side of the fifth protrusion 211 facing the disassembly direction of the second sheath 2. When the protective member 3 is in the first position, the third protrusion 32 abuts against the side of the sixth protrusion 112 facing the disassembly direction of the second sheath 2.

[0049] The extension direction of the sixth protrusion 112 shown in the figure is parallel to the first wall surface of the first sheath 1. Of course, the extension direction of the sixth protrusion 112 is not limited to being parallel to the first wall surface of the first sheath 1. Those skilled in the art can select the extension direction of the sixth protrusion 112 according to actual needs.

[0050] This utility model also provides a vehicle including the aforementioned connector. Because the vehicle of this utility model includes the aforementioned connector, the unlocking end of the locking part 11 is protected by the protective member 3, avoiding the risk of accidental unlocking, thereby improving the stability and safety of the vehicle's electrical connection.
