Connector structure

Abstract

This invention belongs to the field of connector technology and discloses a connector structure. The second body of this connector structure can be inserted into or separated from the first body along a second direction, having a primary locking position and an unlocking position. A secondary locking member slides along the second direction on the first body, having a pre-locking position and a secondary locking position. When the second body is in the primary locking position, a first engaging portion allows the second engaging portion in the pre-locking position to abut against the top of the first engaging portion along a first direction. Under external force, the secondary locking member allows the second engaging portion abutting against the top of the first engaging portion to move along the second direction to the secondary locking position and engage with the first engaging portion. When the second body is in the unlocking position, the first engaging portion separates from the second engaging portion, and a first limiting portion abuts against a first stop portion along a first orientation. The first stop portion can move along the first direction under external force and separate from the first limiting portion. This connector structure has high operational reliability and good safety in use.

Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to connector structures. Background Technology

[0002] A connector structure generally includes a male and a female terminal that mate and connect. When mated, the male and female terminals can transmit current. Typically, a boss is provided on the male terminal, and a cantilever is provided on the female terminal. One end of the cantilever along the mating direction of the male and female terminals has a protrusion, and the other end has a pressing part. When the male and female terminals mate, the cantilever elastically deforms, causing the protrusion to engage with the boss. When the male and female terminals are fully inserted, the elastic restoring force of the cantilever causes the protrusion and boss to elastically lock together, thus achieving mutual locking between the male and female terminals. To unlock, pressing the pressing part raises the protrusion until the protrusion on the cantilever releases its engagement with the boss, allowing the male terminal to be pulled away from the female terminal.

[0003] In related technologies, to reduce the risk of loosening or even separation of the male and female terminals under vibration or other conditions, a secondary lock is usually installed on the female terminal to lock the male and female terminals a second time. After the secondary lock in these technologies locks the male and female terminals, usually only a pulling force is needed to release the secondary lock, allowing the male and female terminals to directly release the primary lock and separate. This results in no separation time difference between the male and female terminals in the connector structure. The same problem of no separation time difference also exists in connector structures without a secondary lock, leading to lower safety and reliability in the connector structure. Summary of the Invention

[0004] The purpose of this invention is to provide a connector structure to solve the aforementioned problems existing in the related art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The connector structure includes:

[0007] The first connector includes a first body having a first stop portion;

[0008] The second connector includes a second body; the second body is provided with a first snap-fit ​​portion and a first limiting portion that are spaced apart along the second direction on a first side along a first direction.

[0009] A secondary locking member is slidably disposed on the first body along the second direction and has a pre-locked position and a secondary locking position; a second latching part is provided on the side of the secondary locking member near the second body;

[0010] The second body can be inserted into or separated from the first body along the second direction, thus having a locking position and an unlocking position. When the second body is in the first locking position, the first engaging portion allows the second engaging portion in the pre-locked position to abut against the top of the first engaging portion along the first direction. The secondary locking member can, under the action of an external force, move the second engaging portion abutting against the top of the first engaging portion along the second direction to the secondary locking position to engage with the first engaging portion. When the second body is in the unlocking position, the first engaging portion separates from the second engaging portion, and the first limiting portion abuts against the first stop portion along the first orientation. The first stop portion can, under the action of an external force, move along the first direction and separate from the first limiting portion. The first direction and the second direction are perpendicular. The first orientation and the second direction are parallel, and the first orientation and the direction in which the second body separates from the first body are parallel and in the same direction.

[0011] As an alternative to the above connector structure, the first body is provided with a first cantilever on a first side along the first direction, the first stop is provided at one end of the first cantilever along the second direction, and the other end of the first cantilever along the second direction is provided with a first pressing part. The first pressing part can drive the first stop to move along the first direction under the action of external force.

[0012] As an alternative to the above connector structure, the secondary locking member is further provided with a second limiting part on the side of the second body along the first direction;

[0013] When the secondary locking member is in the pre-locked position, the second limiting part abuts against the first side of the first stop part along the first orientation;

[0014] When the second body is in the first locking position, the first latching part can also cause the second limiting part to separate from the first stop part along the first direction;

[0015] After the second engaging portion engages with the first engaging portion, the second limiting portion is located between the second engaging portion and the first stop portion and can abut against the second side of the first stop portion along the second orientation, wherein the first orientation and the second orientation are parallel and opposite.

[0016] As an alternative to the above connector structure, the first body is also provided with a second stop portion;

[0017] The secondary locking member has a third limiting part on the side facing away from the second body along the first direction. The third limiting part can abut against the second stop part along the second orientation to limit the secondary locking member to the pre-locked position; and / or, the secondary locking member has a damping part on the side facing away from the second body along the first direction. The damping part can abut against either side of the second stop part along the second direction, and can move from either side of the second stop part to the other side of the second stop part along the second direction under the action of external force.

[0018] As an optional embodiment of the above connector structure, the second side of the first stop portion is provided with a first guide surface distributed at an angle to the first direction. The first guide surface can guide the first limiting portion to move from the first side of the first stop portion to the second side of the first stop portion along the first orientation, and can also guide the first limiting portion to move from the second side of the first stop portion to the first side of the first stop portion along the second orientation; and / or,

[0019] The second side of the first stop portion is provided with a second guide surface that is distributed at an angle to the first direction. The second guide surface can guide the second limiting portion, which is separated from the first stop portion along the first direction, to move along the first orientation to the second side of the first stop portion, and can also guide the second limiting portion to move along the second orientation from the second side of the first stop portion to the first side of the first stop portion.

[0020] As an optional embodiment of the above connector structure, the first latching portion is provided with a third guide surface on the first side near the first limiting portion. The third guide surface can guide the second latching portion to move from the first side of the first latching portion to the top of the first latching portion, and can also guide the second latching portion located at the top of the first latching portion to move to the first side of the first latching portion; and / or,

[0021] A fourth guide surface is provided on the second side of the first latching portion away from the first limiting portion. The fourth guide surface can guide the second latching portion located at the top of the first latching portion to move to the second side of the second latching portion being located in the secondary locking position, and can also guide the second latching portion to move from the secondary locking position to the top of the first latching portion.

[0022] As an alternative to the above connector structure, the first body is further provided with a second cantilever on a first side along the first direction, the second cantilever is provided with a third snap-fit ​​portion at one end along the second direction, and the second body is further provided with a fourth snap-fit ​​portion on a first side along the first direction; when the second body is in the first locking position, the third snap-fit ​​portion and the fourth snap-fit ​​portion snap together.

[0023] As an alternative to the above connector structure, the second cantilever is provided with a second pressing part at the other end along the second direction, and the secondary locking member is also provided with a pressing limiting part on the side facing away from the second body along the first direction; when the secondary locking member is in the secondary locking position, the pressing limiting part restricts the second pressing part from moving along the first direction toward the pressing limiting part.

[0024] As an alternative to the above connector structure, the first body is further provided with an electrical connection piece, and the second body is further provided with an electrical connection terminal.

[0025] When the second body is in the first locked position, the electrical connecting piece is in contact with the electrical connecting terminal; when the second body is in the unlocked position, the electrical connecting piece is separated from the electrical connecting terminal.

[0026] As an alternative to the above connector structure, the first body is recessed at one end along the second direction with a mounting groove, and the inner wall of the mounting groove is recessed with a limiting groove extending along the first direction.

[0027] The electrical connector includes a plug-in limiting part and a conductive part connected together. The plug-in limiting part can be plugged into the mounting groove along the second direction so that the conductive part is limited to the limiting groove. The electrical connector terminal can be plugged into the limiting groove and contact the conductive part.

[0028] The beneficial effects of this invention are:

[0029] This invention provides a connector structure comprising a first connector, a second connector, and a secondary locking member. Before connecting the first and second connectors, the secondary locking member is slid to a pre-locked position along a second direction. When the second body is in the first locking position, the first and second connectors complete a first locking. At this time, the second engaging portion in the pre-locked position abuts against the top of the first engaging portion along a first direction, applying a force along a first orientation to the secondary locking member, pushing the secondary locking member to move along the first orientation until the second engaging portion engages with the first engaging portion at the secondary locking position, thus completing the secondary locking of the first and second connectors. Compared to the prior art which only performs a single locking, this invention effectively improves the connection reliability of the first and second connectors in the connector structure, thereby improving the operational reliability of the connector structure.

[0030] When separating the second connector from the first connector, a force is first applied to the secondary locking member along the second orientation, which is parallel to and opposite to the first orientation. The secondary locking member is pulled along the second orientation until it reaches the pre-lock position. At this point, the engagement between the second locking part and the first locking part is released, and the secondary lock is unlocked. The second locking part abuts against the top of the first locking part along the first direction. Then, a force is applied to the second connector along the first orientation, pulling the second connector along the first orientation to complete one locking and unlocking operation. This causes the first limiting part to move along the first orientation until it abuts against the first stop. Understandably, the second connector can no longer move along the first orientation at this point. Then, a force is applied to the first stop, causing the first stop to move along the first direction and separate from the first limiting part. Then, the second connector is pulled along the first orientation to complete the separation of the first and second connectors. With this configuration, after the first limiting part moves along the first direction to abut against the first stop part, and before the first stop part moves along the first direction to separate from the first limiting part, a force is applied to the first stop part along the first direction to separate the first stop part from the first limiting part. This process creates a separation time difference between the first connector and the second connector, thereby effectively avoiding the problem of poor safety and reliability of connectors caused by the lack of a separation time difference between the male and female ends in the prior art.

[0031] Therefore, this connector structure has high operational reliability and good safety in use. Attached Figure Description

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0062] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0063] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0065] In related technologies, after the secondary lock locks the male and female terminals, it is usually only necessary to apply a pulling force to the secondary lock to release the secondary lock and allow the male and female terminals to directly release the primary lock and separate from each other. This results in no separation time difference between the male and female terminals of the connector structure. The same problem of no separation time difference also exists for connector structures without a secondary lock.

[0066] The lack of a separation time difference can lead to the following problems in the connector structure:

[0067] First, an electric arc may be generated at the moment the male and female terminals are disconnected due to a sudden change in current;

[0068] Secondly, for systems using connector structures, the rapid separation of the male and female terminals of the electrical connector can cause the system to fail to respond to the separation of the male and female terminals, leading to safety accidents.

[0069] This results in lower safety and reliability of the connector structure.

[0070] This invention provides a connector structure, such as Figures 1-8 As shown, the connector structure includes a first connector 1, a second connector 2, and a secondary locking member 3. The first connector 1 includes a first body 11, which has a first stop portion 121. The second connector 2 includes a second body 21, which has a first engaging portion 22 and a first limiting portion 23 spaced apart along a second direction on a first side along a first direction. The secondary locking member 3 is slidably disposed on the first body 11 along the second direction, having a pre-locked position and a secondary locked position. A second engaging portion 311 is provided on the side of the secondary locking member 3 near the second body 21 along the first direction. The second body 21 can be inserted into or separated from the first body 11 along the second direction, having a primary locked position and an unlocked position. When the second body 21 is in the primary locking position, the first engaging portion 22 allows the second engaging portion 311, which is in the pre-locking position, to abut against the top of the first engaging portion 22 along a first direction. The secondary locking member 3, under external force, moves the second engaging portion 311, which abuts against the top of the first engaging portion 22, along a second direction to the secondary locking position and engage with the first engaging portion 22. When the second body 21 is in the unlocked position, the first engaging portion 22 separates from the second engaging portion 311, and the first limiting portion 23 abuts against the first stop portion 121 along a first orientation. The first stop portion 121, under external force, moves along the first direction and separates from the first limiting portion 23. The first and second directions are perpendicular. The first and second orientations are parallel, and the first orientation and the direction in which the second body 21 separates from the first body 11 are parallel and in the same direction.

[0071] Before connecting the first connector 1 and the second connector 2, the secondary locking member 3 is slid to the pre-lock position along the second direction. When the second body 21 is in the primary locking position, the first connector 1 and the second connector 2 complete the primary locking. At this time, the second latching part 311, located in the pre-lock position, abuts against the top of the first latching part 22 along the first direction, applying a force along the first orientation to the secondary locking member 3, pushing the secondary locking member 3 to move along the first orientation until the second latching part 311 engages with the first latching part 22 at the secondary locking position, thus completing the secondary locking of the first connector 1 and the second connector 2. Compared with the prior art that only performs a primary locking, this method can effectively improve the connection reliability of the first connector 1 and the second connector 2 in the connector structure, thereby improving the operational reliability of the connector structure.

[0072] When separating the second connector 2 from the first connector 1, a force is first applied to the secondary locking member 3 along the second orientation, which is parallel to and opposite to the first orientation. The secondary locking member 3 is pulled to move along the second orientation until it reaches the pre-lock position. At this point, the engagement between the second latching part 311 and the first latching part 22 is released, and the secondary lock is unlocked. The second latching part 311 abuts against the top of the first latching part 22 along the first direction. Then, a force is applied to the second connector 2 along the first orientation, and the second connector 2 is pulled to move along the first orientation to complete one locking and unlocking operation. This causes the first limiting part 23 to move along the first orientation to abut against the first stop part 121. It is understood that at this point, the second connector 2 can no longer move along the first orientation. Then, a force is applied to the first stop part 121, causing the first stop part 121 to move along the first direction and separate from the first limiting part 23. Then, the second connector 2 is pulled to move along the first orientation, thus pulling the first connector 1 and the second connector 2 to complete the separation. With this configuration, after the first limiting part 23 moves along the first direction to abut against the first stop part 121, before the first stop part 121 moves along the first direction and separates from the first limiting part 23, that is, during the process of applying a force along the first direction to the first stop part 121 to separate from the first limiting part 23, a separation time difference can be formed between the first connector 1 and the second connector 2. This can effectively avoid the problem of poor safety and reliability of connectors caused by the lack of separation time difference between the male and female ends in the prior art.

[0073] Therefore, this connector structure has high operational reliability and good safety in use.

[0074] It is understandable that the second orientation is the direction in which the first body 11 separates from the second body 21.

[0075] Specifically, Figure 4 In this context, direction ab is the first direction. Figure 4The cd direction in the equation is the second direction. This is understandable. Figure 3 , Figure 4 and Figure 6 The up and down directions are both the first direction. Figure 3 , Figure 4 and Figure 6 Both the left and right directions are the second direction. Furthermore, Figure 4 The direction from d to c is the first orientation. Figure 4 The direction from c to d is the second orientation.

[0076] Among them, such as Figures 1-7 As shown, the first body 11 has a first cantilever 12 on a first side along a first direction, a first stop 121 is provided at one end of the first cantilever 12 along a second direction, and a first pressing part 122 is provided at the other end of the first cantilever 12 along the second direction. The first pressing part 122 can drive the first stop 121 to move along the first direction under the action of external force. Specifically, as... Figure 4 As shown, the first pressing part 122 can drive the first stop part 121 to move along the direction from a to b, thereby separating the first stop part 121 from the first limiting part 23. Furthermore, the elastic restoring force of the first cantilever 12 can drive the first stop part 121 to move along the direction from b to a, thereby returning the first stop part 121 to a position where it can abut against the first limiting part 23 along the first orientation.

[0077] When the first limiting part 23 moves along the first orientation to abut against the first stop part 121, pressing the first pressing part 122 along the first direction causes the first cantilever 12 to move the first stop part 121 along the first direction and separate it from the first limiting part 23, thereby allowing the second connector 2 to continue moving along the first orientation until it is completely separated from the second connector 2. When the first stop part 121 separates from the first limiting part 23 along the first direction, and the first limiting part 23 moves away from the first stop part 121 along the first orientation, releasing the first pressing part 122 allows the elastic restoring force of the first cantilever 12 to move the first stop part 121, causing the first stop part 121 to return to a position where it can abut against the first limiting part 23 along the first orientation.

[0078] Specifically, the connection point on the first cantilever 12 that connects to the first body 11 is located between the first pressing part 122 and the first stop part 121. When the first pressing part 122 is pressed along the first direction, the connection point on the first cantilever 12 that connects to the first body 11 undergoes elastic deformation.

[0079] Optionally, along the second direction, the distance between the connection point of the first cantilever 12 to the first body 11 and the first pressing part 122 is smaller than the distance between the connection point of the first cantilever 12 to the first body 11 and the first stop part 121. This allows the first stop part 121 to move along the first direction and separate from the first limiting part 23 by applying a smaller force. In other embodiments, the distance between the connection point of the first cantilever 12 to the first body 11 and the first pressing part 122 may also be equal to the distance between the connection point of the first cantilever 12 to the first body 11 and the first stop part 121. Alternatively, the distance between the connection point of the first cantilever 12 to the first body 11 and the first pressing part 122 may be greater than the distance between the connection point of the first cantilever 12 to the first body 11 and the first stop part 121.

[0080] Optionally, such as Figures 2-7 As shown, the secondary locking member 3 is further provided with a second limiting part 312 on the side of the secondary locking member 3 closest to the second body 21 along the first direction. When the secondary locking member 3 is in the pre-locked position, the second limiting part 312 abuts against the first side of the first stop part 121 along the first orientation. When the second body 21 is in the primary locking position, the first engaging part 22 can also separate the second limiting part 312 from the first stop part 121 along the first direction. After the second engaging part 311 engages with the first engaging part 22, the second limiting part 312 is located between the second engaging part 311 and the first stop part 121 and can abut against the second side of the first stop part 121 along the second orientation.

[0081] By setting the second limiting part 312, the secondary locking member 3 can be limited to the pre-lock position once by sliding along the first direction before connecting the first connector 1 and the second connector 2. This allows the second locking part 311, which is in the first locking position, to be directly pushed to abut the top of the first locking part 22 along the first direction when the second body 21 is in the first locking position. Then, a force along the first direction is applied to the secondary locking member 3 to push it to move along the first direction, so that the second locking part 311 can engage with the first locking part 22, which can effectively improve the assembly efficiency of the connector structure.

[0082] Since the secondary locking member 3 is slidably disposed on the first body 11 along the second direction, the placement position of the secondary locking member 3 along the first direction is relatively fixed. By providing the second limiting part 312, when the second body 21 is in the first locking position, the second engaging part 311, which is in the pre-locking position, is pushed to abut against the top of the first engaging part 22 along the first direction. It can be understood that at this time, the secondary locking member 3 undergoes elastic deformation and / or slight movement along the first direction, causing the second limiting part 312 to separate from the first stop part 121 along the first direction. Then, by applying a force along the first direction to the secondary locking member 3, the secondary locking member 3 can be pushed to move along the first direction, thereby causing the second engaging part 311 to engage with the first engaging part 22.

[0083] When the second latching part 311 latches with the first latching part 22, that is, when the secondary locking member 3 is in the secondary locking position, the second limiting part 312 is located between the second latching part 311 and the first stop part 121 and can abut against the second side of the first stop part 121 along the second orientation. This can effectively reduce the risk of the secondary locking member 3 moving along the second orientation under vibration and other conditions, thereby effectively improving the working reliability of the secondary locking member 3 and further improving the working reliability of the connector structure.

[0084] Specifically, such as Figure 1 As shown, the secondary locking member 3 and the first body 11 each have a first slide rail extending in the second direction and a first slider 34, which is slidably disposed within the first slide rail. This allows the secondary locking member 3 to slide along the second direction on the first body 11.

[0085] In this embodiment, as Figure 1 As shown, an exemplary example is taken where the secondary locking member 3 has a first slider 34 and the first body 11 has a first slide rail. In other embodiments, the secondary locking member 3 has a first slide rail and the first body 11 has a first slider 34.

[0086] Optionally, such as Figure 1 As shown, there are two first slide rails and two first sliders 34, with each pair corresponding to the other. This improves the stability and smoothness of the secondary locking member 3 sliding along the second direction on the first body 11.

[0087] In this embodiment, as Figure 1As shown, the secondary locking member 3 includes a locking body 31, a second engaging portion 311, and a second limiting portion 312, both disposed on the locking body 31. Two first sliders 34 are disposed on opposite sides of the locking body 31 along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. This further improves the stability and smoothness of the secondary locking member 3 sliding along the second direction. In other embodiments, the number of first sliders 34 and first slide rails may also be one each.

[0088] Optionally, such as Figure 3 , Figure 4 and Figure 6 As shown, the first body 11 is also provided with a second stop 13.

[0089] Optionally, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the secondary locking member 3 is provided with a third limiting part 32 on the side facing away from the second body 21 along the first direction. The third limiting part 32 can abut against the second stop part 13 along the second direction to limit the secondary locking member 3 to the pre-lock position.

[0090] By setting the second stop part 13 and the third limiting part 32, the secondary locking member 3 can be limited to the pre-locking position at one time when sliding along the second direction, thereby effectively improving the disassembly efficiency of the connector structure; secondly, it can effectively prevent the secondary locking member 3 from detaching from the first body 11 along the second direction, making it convenient to connect the first connector 1 and the second connector 2 next time.

[0091] Optionally, such as Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the secondary locking member 3 is provided with a damping part 33 on the side opposite to the second body 21 along the first direction. The damping part 33 can abut against any side of the second stop part 13 along the second direction, and can move from any side of the second stop part 13 to the other side of the second stop part 13 along the second direction under the action of external force.

[0092] When the secondary locking member 3 slides relative to the first body 11 along the first orientation, the damping part 33 can abut against the first side of the second stop part 13 along the first orientation, and can move from the first side of the second stop part 13 to the second side of the second stop part 13 along the first orientation under the action of external force. The damping part 33 provides damping to push the secondary locking member 3 to slide along the first orientation.

[0093] When the secondary locking member 3 slides relative to the first body 11 along the second orientation, the damping part 33 can abut against the second side of the second stop part 13 along the second orientation, and can move from the second side of the second stop part 13 to the first side of the second stop part 13 along the second orientation under the action of external force. The damping part 33 provides damping for pulling the secondary locking member 3 to slide along the second orientation.

[0094] Further, optionally, in this embodiment, as Figures 1-4 , Figure 6 and Figure 7 As shown, when the damping part 33 moves along the first direction from the first side of the second stop part 13 to the second side of the second stop part 13 under the action of external force, the secondary locking member 3 is in the secondary locking position. That is, at this time, the first latching part 22 and the second latching part 311 are latched, which makes it easy for assembly workers to know whether the secondary locking is completed, thereby further improving the assembly efficiency of the connector structure.

[0095] Further, optionally, in this embodiment, as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, when the damping part 33 moves along the second orientation from the second side of the second stop part 13 to the first side of the second stop part 13 under the action of external force, the third limiting part 32 abuts against the second stop part 13 along the second orientation. That is, the secondary locking member 3 is limited to the pre-locked position, so that the assembly operator can clearly see whether the secondary lock has been unlocked, and whether the secondary locking member 3 has moved to the pre-locked position along the second orientation, thereby further improving the disassembly efficiency of the connector structure.

[0096] Further, optionally, in this embodiment, as Figure 1 As shown, the damping part 33 and the third limiting part 32 form a functional group. There are two functional groups and two second stop parts 13, with each functional group and the second stop part 13 corresponding to one another. Furthermore, the two functional groups are correspondingly located on the side of the two first sliders 34 facing away from the second body 21 along the first direction, and both functional groups are located on the side of the corresponding first slider 34 along the third direction closer to the locking body 31. This arrangement further improves the operational reliability and stability of the secondary locking member 3. In other embodiments, the number of damping parts 33, the third limiting part 32, and the second stop part 13 may also be one.

[0097] Further, optionally, in this embodiment, as Figure 1As shown, the locking body 31 and the first slider 34 are distributed at an acute angle. Along the first direction, the locking body 31 is inclined downwards, and the side of the locking body 31 on which the second engaging portion 311 is provided is located at the bottom. This ensures good engagement reliability between the first engaging portion 22 and the second engaging portion 311, and allows the locking body 31 to undergo elastic deformation so that the second engaging portion 311 can abut against the top of the first engaging portion 22 along the first direction, thereby further improving the working reliability and stability of the secondary locking member 3. In other embodiments, the locking body 31 and the first slider 34 may also be arranged parallel to each other along the first direction.

[0098] Optionally, in this embodiment, the locking body 31, the second latching portion 311, the second limiting portion 312, the third limiting portion 32, the damping portion 33, and the pressing limiting portion 313 of the secondary locking member 3 are all integrally formed. This reduces the number of parts and further improves assembly efficiency. Furthermore, in this embodiment, the secondary locking member 3 is made of plastic material, making it insulating and possessing a certain degree of elastic deformation capability. In other embodiments, other insulating materials with a certain degree of elastic deformation capability can also be used to make the secondary locking member 3.

[0099] Optionally, such as Figure 2 and Figure 3 As shown, the second side of the first stop portion 121 is provided with a first guide surface 1211 distributed at an angle to the first direction. The first guide surface 1211 can guide the first limiting portion 23 to move from the first side of the first stop portion 121 to the second side of the first stop portion 121 along the first orientation, and can also guide the first limiting portion 23 to move from the second side of the first stop portion 121 to the first side of the first stop portion 121 along the second orientation. Specifically, along the second direction, the top end of the first guide surface 1211 is farther away from the first side of the first stop portion 121 relative to the bottom end of the first guide surface 1211.

[0100] After the first stop portion 121 moves along the first direction and separates from the first limiting portion 23, during the process of the first limiting portion 23 moving along the first orientation, the first guide surface 1211 guides the first limiting portion 23 to move along the first orientation from the first side of the first stop portion 121 to the second side of the first stop portion 121, thereby effectively improving the disassembly efficiency of the connector structure. During the process of inserting the first body 11 and the second body 21, the first guide surface 1211 guides the first limiting portion 23 to move along the second orientation from the second side of the first stop portion 121 to the first side of the first stop portion 121, thereby further improving the assembly efficiency of the connector structure.

[0101] Further optional, such as Figures 1-3As shown, the first limiting part 23 is provided with a fifth guide surface 231. The first guide surface 1211 can slide in contact with the fifth guide surface 231 to guide the first limiting part 23 to move along a first orientation from the first side of the first stop part 121 to the second side of the first stop part 121, and can also guide the first limiting part 23 to move along a second orientation from the second side of the first stop part 121 to the first side of the first stop part 121. This can further improve the assembly and disassembly efficiency of the connector structure.

[0102] Optionally, such as Figure 2 and Figure 3 As shown, a second guide surface 1212 is provided on the second side of the first stop portion 121 at an angle to the first direction. The second guide surface 1212 can guide the second limiting portion 312, which is separated from the first stop portion 121 along the first direction, to move along the first orientation to the second side of the first stop portion 121, and can also guide the second limiting portion 312 to move along the second orientation from the second side of the first stop portion 121 to the first side of the first stop portion 121. This can further improve the assembly and disassembly efficiency of the connector structure. Specifically, along the second direction, the top end of the second guide surface 1212 is closer to the first side of the first stop portion 121 than the bottom end of the second guide surface 1212.

[0103] It is understood that, in this embodiment, as Figure 2 As shown, the first guide surface 1211 and the second guide surface 1212 are distributed in a trumpet shape, and along the second direction, the larger end of the trumpet shape is closer to the first side of the first stop portion 121 than the smaller end of the trumpet shape.

[0104] Further optional, such as Figure 2 As shown, the second limiting part 312 is also provided with a sixth guide surface 3121. The sixth guide surface 3121 can slide in contact with the second guide surface 1212 to guide the second limiting part 312, which is separated from the first stop part 121 along the first direction, to move along the first orientation to the second side of the first stop part 121. It can also guide the second limiting part 312 to move along the second orientation from the second side of the first stop part 121 to the first side of the first stop part 121. This can further improve the assembly and disassembly efficiency of the connector structure.

[0105] Optionally, such as Figure 1 and Figures 3-5As shown, the first locking portion 22 is provided with a third guide surface 221. The third guide surface 221 can guide the second locking portion 311 from the first side of the first locking portion 22 to the top of the first locking portion 22, and can also guide the second locking portion 311 located at the top of the first locking portion 22 to the first side of the first locking portion 22. Specifically, during the process of pushing the secondary locking member 3 to move along the first orientation, the second locking portion 311 moves upward along the third guide surface 221 to the top of the first locking portion 22 and abuts against the top of the first locking portion 22, thereby improving the efficiency of the first locking; during the process of pulling the secondary locking member 3 to move along the second orientation, the second locking portion 311 moves downward along the third guide surface 221 to the first side of the first locking portion 22, thereby further improving the disassembly efficiency.

[0106] Optionally, such as Figure 1 and Figures 3-5 As shown, the first latching part 22 is provided with a fourth guide surface 222. The fourth guide surface 222 can guide the second latching part 311 located at the top of the first latching part 22 to move to the second side of the second latching part 311 in the secondary locking position, and can also guide the second latching part 311 from the secondary locking position to the top of the first latching part 22. When the second latching part 311 moves upward along the third guide surface 221 to the top of the first latching part 22 and abuts against the top of the first latching part 22, while the secondary locking member 3 continues to move along the first direction, the second latching part 311 moves downward along the fourth guide surface 222 until the first latching part 22 and the second latching part 311 are latched together, reaching the secondary locking position, thereby improving the efficiency of secondary locking; when unlocking the secondary lock, the secondary locking member 3 is pulled along the second direction, and the second latching part 311 moves along the fourth guide surface 222 to the top of the first latching part 22 to achieve secondary locking unlocking, and can further improve the disassembly efficiency.

[0107] Among them, such as Figures 1-7 and Figure 9 As shown, the first body 11 is further provided with a second cantilever 14 on a first side along the first direction, and a third engaging portion 141 is provided at one end of the second cantilever 14 along the second direction. The second body 21 is further provided with a fourth engaging portion 24 on a first side along the first direction. When the second body 21 is in the first locking position, the third engaging portion 141 and the fourth engaging portion 24 engage to achieve a first locking.

[0108] Optionally, such as Figures 1-7As shown, the second cantilever 14 has a second pressing part 142 at the other end along the second direction, and the secondary locking member 3 has a pressing limiting part 313 on the side facing away from the second body 21 along the first direction. When the secondary locking member 3 is in the secondary locking position, the pressing limiting part 313 restricts the second pressing part 142 from moving along the first direction toward the pressing limiting part 313. With this configuration, when both the primary and secondary locking are completed, the pressing limiting part 313 can restrict the second pressing part 142 from moving along the first direction toward the pressing limiting part 313, thereby unlocking the primary lock and further improving the operational reliability of the connector structure.

[0109] Specifically, such as Figure 4 As shown, the second pressing part 142 can drive the third engaging part 141 to move in the direction from a to b, thereby separating the third engaging part 141 from the fourth engaging part 24. Furthermore, the elastic restoring force of the second cantilever 14 can drive the third engaging part 141 to move in the direction from b to a, thereby returning the third engaging part 141 to a position where it can engage with the fourth engaging part 24.

[0110] Specifically, the connection point between the second cantilever 14 and the first body 11 is located between the third latching part 141 and the second pressing part 142. When the second pressing part 142 is pressed along the first direction, the connection point between the second cantilever 14 and the first body 11 undergoes elastic deformation.

[0111] Optionally, along the second direction, the distance between the connection point on the second cantilever 14 to the first body 11 and the second pressing part 142 is less than the distance between the connection point on the second cantilever 14 to the first body 11 and the third locking part 141. This allows the third locking part 141 to move along the first direction and separate from the fourth locking part 24 by applying a smaller force. In other embodiments, the distance between the connection point on the second cantilever 14 to the first body 11 and the second pressing part 142 may also be equal to the distance between the connection point on the second cantilever 14 to the first body 11 and the third locking part 141. Alternatively, the distance between the connection point on the second cantilever 14 to the first body 11 and the second pressing part 142 may be greater than the distance between the connection point on the second cantilever 14 to the first body 11 and the third locking part 141.

[0112] Optionally, such as Figure 2 As shown, the third latching portion 141 is provided with a seventh guide surface 1411, which is used to guide the third latching portion 141 to latch with the fourth latching portion 24. This can further improve the assembly efficiency of the connector structure.

[0113] Optionally, such as Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the fourth latching portion 24 is provided with an eighth guide surface 241, which is used to guide the third latching portion 141 to latch with the fourth latching portion 24. This can further improve the assembly efficiency of the connector structure.

[0114] Among them, such as Figure 2 , Figure 3 and Figures 5-10 As shown, the first body 11 also includes an electrical connecting piece 15, and the second body 21 also includes an electrical connecting terminal 25. When the second body 21 is in the locked position, the electrical connecting piece 15 is in contact with the electrical connecting terminal 25; when the second body 21 is in the unlocked position, the electrical connecting piece 15 is separated from the electrical connecting terminal 25. This arrangement ensures a separation time difference between the electrical connecting terminal 25 and the electrical connecting piece 15, thereby effectively guaranteeing the operational reliability and safety of the connector structure.

[0115] Optionally, such as Figures 2-10 As shown, the first body 11 has a recessed mounting groove 111 at one end along the second direction, and the inner wall of the mounting groove 111 has a limiting groove 112 extending along the first direction. The electrical connector 15 includes a plug-in limiting part 153 and a conductive part 151 connected to each other. The plug-in limiting part 153 can be plugged into the mounting groove 111 along the second direction, so that the conductive part 151 is limited to the limiting groove 112. The electrical connector terminal 25 can be plugged into the limiting groove 112 and contact the conductive part 151. This achieves the goal of limiting the installation position of the electrical connector 15 in the first body 11 and enabling the electrical connector 15 to contact and conduct electricity with the electrical connector terminal 25.

[0116] In this embodiment, as Figure 10 As shown, the exemplary setting of the insertion limiting part 153 includes a first V-shaped elastic insertion part 152 and a second V-shaped limiting part 153. One end of the guide part is connected to one end of the elastic insertion part 152, and the other end of the conductive part 151 is connected to one end of the limiting part 153. When the elastic insertion part 152 is inserted into the mounting groove 111 along the second orientation, the elastic restoring force of the elastic insertion part 152 enables the two opposing abutting surfaces on the elastic insertion part 152 to abut against the first groove inner wall and the second groove inner wall of the mounting groove 111, which are opposite to each other and spaced apart along the first direction. The limiting part 153 abuts against the second groove inner wall along the first direction and abuts against the groove inner wall of the limiting groove 112 along the first orientation. Along the first direction, the first groove inner wall is close to the first cantilever 12 of the first body 11 relative to the second groove inner wall.

[0117] When the insertion limiting part 153 is inserted into the mounting groove 111, a force is applied to the elastic insertion part 152, causing the two abutting surfaces of the insertion limiting part 153 to approach each other. After the insertion limiting part 153 is inserted into the mounting groove 111, the elastic restoring force of the elastic insertion part 152 causes the two abutting surfaces of the elastic insertion part 152 to abut against the inner walls of the first groove and the second groove, respectively. The limiting part 153 abuts against the inner wall of the second groove along the first direction and against the inner wall of the limiting groove 112 along the first orientation. This achieves the limitation of the installation position of the electrical connector 15 within the first body 11 and facilitates the installation and removal of the electrical connector 15.

[0118] Furthermore, in this embodiment, as Figure 10 As shown, the exemplary configuration of the elastic connector 152 includes two connected sub-elastic connectors 1521, which form a first V-shaped elastic connector 152. The included angle between the two sub-elastic connectors 1521 is an acute angle. That is, the included angle corresponding to the first V-shape is an acute angle.

[0119] In other embodiments, the elastic insertion part 152 may also be trapezoidal in shape, with the two inclined sides of the trapezoid abutting against the inner walls of the first and second grooves in a corresponding manner along the first direction, which can also limit the setting position of the insertion limiting part 153 along the first direction.

[0120] Furthermore, in this embodiment, as Figure 10 As shown, the included angle corresponding to the second V-shape is set to an obtuse angle, which is an example of setting the second V-shape.

[0121] In other embodiments, the limiting part 153 may also be L-shaped, which can also achieve the limiting part 153 abutting against the inner wall of the second groove along the first direction and abutting against the inner wall of the limiting groove 112 along the first orientation. It can also limit the setting position of the insertion limiting part 153 along the second direction.

[0122] Furthermore, in this embodiment, as Figure 10 As shown, one of its resilient plug-in portions 1521 has a first bent portion 1522, and the free end of the first bent portion 1522 abuts against another resilient plug-in portion 152. This ensures that after the electrical connector 15 is disposed within the first body 11, the included angle between the two resilient plug-in portions 152 remains approximately a fixed angle, thereby improving the stability of the electrical connector 15's placement position within the first body 11. Exemplarily, one first bent portion 1522 is provided.

[0123] Furthermore, in this embodiment, as Figure 10As shown, one of its elastic insertion portions 1521 also has a second bent portion 1523, which abuts against the inner wall of the mounting groove 111 along a first orientation. This further limits the placement position of the insertion limiting portion 153 along the second direction, further prevents the electrical connector 15 from detaching from the first body 11 along the second direction, and further enhances the effect of limiting the placement position of the electrical connector 15 within the first body 11. For example, two second bent portions 1523 are provided, and the two second bent portions 1523 are spaced apart along a third direction.

[0124] Furthermore, in this embodiment, as Figure 10 As shown, the conductive part 151 is exemplaryly configured in a third V-shape, with its opening facing the first cantilever 12. The conductive part 151 has a limiting insertion hole 1511 extending along a second direction. The electrical connection terminal 25 can be sequentially inserted into the limiting groove 112 and the limiting insertion hole 1511, and contacts the inner wall of the limiting insertion hole 1511. Further, the included angle corresponding to the third V-shape is an obtuse angle. In other embodiments, the included angle corresponding to the third V-shape may also be a right angle or an acute angle.

[0125] In other embodiments, the conductive portion 151 may be trapezoidal or U-shaped, with its opening facing the first cantilever 12. The conductive portion 151 has a limiting insertion hole 1511 extending along a second direction, allowing the electrical connection terminal 25 to be sequentially inserted into the limiting groove 112 and the limiting insertion hole 1511, and to contact the inner wall of the limiting insertion hole 1511. This also enables electrical connection between the electrical connection piece 15 and the electrical connection terminal 25.

[0126] Furthermore, in this embodiment, the electrical connector 15 is formed by bending a conductive sheet. In other embodiments, the electrical connector 15 may also be formed by stamping or milling.

[0127] Furthermore, in this embodiment, as Figure 10 As shown, the exemplary configuration includes two electrical connection terminals 25 and one electrical connection piece 15.

[0128] It is understandable that the structure of the electrical connector 15 can be adapted to meet the actual working conditions, so that the electrical connector 15 can be easily installed and removed and confined within the mounting groove 111, and that the electrical connector 15 can be electrically connected to the electrical connector terminal 25.

[0129] The specific structure of the insertion and cooperation between the first body 11 and the second body 21, the specific structure of the first body 11, and the specific structure of the second body 21 are all existing technologies, and therefore will not be described in detail here.

[0130] Optionally, such as Figure 1 , Figure 3 , Figure 4 and Figures 6-9 As shown, the first body 11 and the second body 21 are provided with a second slide rail 113 extending along the second direction and a second slider 26, respectively. The second slide rail 113 and the second slider 26 are slidably engaged. This improves the smoothness of the insertion or separation of the first body 11 and the second body 21 along the second direction.

[0131] Further optional, such as Figure 10 As shown, there are at least two second slide rails 113 and at least two second sliders 26, with each pair of slide rails 113 and sliders corresponding to one another. This further improves the smoothness of the insertion or separation of the first body 11 and the second body 21 along the second direction.

[0132] In this embodiment, as Figure 10 As shown, an exemplary embodiment uses two second slide rails 113 and two second sliders 26, with both second sliders 26 disposed on the second body 21 and both second slide rails 113 disposed on the first body 11. In other embodiments, the second slide rails 113 may be disposed on the second body 21 and the second sliders 26 may be disposed on the first body 11. In other embodiments, the number of second slide rails 113 and second sliders 26 may be one or three, etc.

[0133] Specifically, in this embodiment, the first body 11, the second body 21, the first cantilever 12, and the second cantilever 14 are all made of plastic material. This ensures that the first body 11, the second body 21, the first cantilever 12, and the second cantilever 14 are all insulated, and that the first cantilever 12 and the second cantilever 14 both have a certain elastic deformation capability. In other embodiments, other insulating materials with a certain elastic deformation capability may also be used to make the first body 11, the second body 21, the first cantilever 12, and the second cantilever 14.

[0134] like Figures 1-10 As shown, the assembly and disassembly process of this connector structure is as follows:

[0135] Before connecting the first connector 1 and the second connector 2, the secondary locking member 3 is slid along the second direction to the pre-lock position. At this time, the second limiting part 312 abuts against the first side of the first stop part 121 along the first orientation.

[0136] When connecting the first connector 1 and the second connector 2, the second body 21 is inserted into the first body 11 along the second orientation until the second body 21 is in the first locking position. During this process, the first latching part 22 on the first body 11 pushes the second latching part 311, which is in the pre-locking position, to move along the third guide surface 221 to the top of the first latching part 22 and abuts against the top of the first latching part 22 along the first direction. The secondary locking member 3 undergoes elastic deformation and / or slight movement along the first direction, causing the second limiting part 312 to separate from the first stop part 121 along the first direction. Then, the second locking member 3 is moved towards the second locking position. The locking member 3 applies a force along the first orientation, pushing the secondary locking member 3 to move along the first orientation. The second engaging part 311 moves along the fourth guide surface 222 until the first engaging part 22 engages with the second engaging part 311, reaching the secondary locking position. The pressing limiting part 313 restricts the second pressing part 142 from moving towards the pressing limiting part 313 along the first direction. During this process, the second limiting part 312 moves to the second side of the first stop part 121 under the guidance of the second guide surface 1212 and the sixth guide surface 3121 and is located between the first stop part 121 and the second engaging part 311. This completes the primary and secondary locking of the first connector 1 and the second connector 2.

[0137] When separating the second connector 2 from the first connector 1, a force is first applied to the secondary locking member 3 along the second orientation, pulling the second latching part 311 of the secondary locking member 3 to move to the top of the first latching part 22 under the guidance of the fourth guide surface 222, completing the secondary locking and unlocking. During this process, the second limiting part 312 moves to the first side of the first stop part 121 under the guidance of the second guide surface 1212 and the sixth guide surface 3121 and remains separated from the first stop part 121 along the first direction. The pressing limiting part 313 moves away from the second pressing part 142 along the second orientation; then the second pressing part 142 is pressed to make The third locking portion 141 and the fourth locking portion 24 are separated. Then, a force along the first direction is applied to the second body 21, pulling the second body 21 relative to the first body 11 until the first limiting portion 23 abuts against the first side of the first stop portion 121, completing one locking and unlocking operation. Then, the first pressing portion 122 is pressed to separate the first stop portion 121 and the first limiting portion 23 along the first direction, completing three unlocking operations. Then, a force along the first direction is applied to the second body 21 again, pulling the second body 21 relative to the first body 11 until the second connector 2 separates from the first connector 1. This completes the first locking and unlocking, second locking and unlocking, and third unlocking operations of the first connector 1 and the second connector 2.

[0138] After the first limiting part 23 moves along the first orientation to abut against the first stop part 121, before the first stop part 121 moves along the first direction and separates from the first limiting part 23, that is, during the process of applying a force along the first direction to the first stop part 121 to separate the first stop part 121 from the first limiting part 23, a separation time difference can be formed between the first connector 1 and the second connector 2. This can effectively avoid the problem of poor safety and reliability of connectors caused by the lack of separation time difference between the male and female ends in the prior art.

[0139] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention.
