A connector with a locking mechanism

Abstract

This invention relates to a connector with a locking mechanism, comprising a plug, a socket, and a locking mechanism. The plug has a socket, and the end of the socket is inserted into the socket. The locking mechanism is disposed within the plug and includes a locking element and an actuating element. The actuating element drives the locking element to move radially along the socket, causing the end of the locking element to enter or disengage from the socket, thereby locking or disengaging the plug and socket. In this invention, the radial displacement of the locking mechanism along the socket ensures that the end of the locking element fully engages in locking, preventing breakage due to partial support. Furthermore, when the plug and socket are engaged, the applied external force only needs to overcome the elastic force of the elastic element, causing the locking element to move a short distance radially along the socket, resulting in reasonable force application and convenient operation. During operation, the fixed-axis rotational motion of the cam rod is converted into the translational motion of the locking element, with a small rotation angle and convenient execution. The spatial layout is unaffected by the movement of the actuating element.

Description

Technical Field

[0001] This invention relates to the field of connector structure technology, and in particular to a connector with a locking mechanism. Background Technology

[0002] With the rise of the energy storage industry, connectors in the energy storage industry are also gradually developing towards miniaturization and ease of operation. Connectors mainly play the role of connection and conduction. Current energy storage connectors generally include a socket and a plug that is inserted into the socket for conduction. In order to ensure a more stable connection between the plug and the socket after insertion and conduction, a button locking mechanism is generally set on the plug. The plug and socket are locked by the button locking mechanism to prevent the plug and socket from accidentally disengaging, thus ensuring the stability of the connection.

[0003] The utility model patent with patent number 202122827928.5 relates to a button locking mechanism for an energy storage connector, the locking principle of which is mainly as follows: [Combined with...] Figure 1 As shown, taking point A, where the outer contour of the connector 111 is located, as an example, the locking member 31 is displaced along the tangent direction at point A, and has a locking position (the position corresponding to the thick solid line in the figure) and an unlocking position (the position corresponding to the thin solid line in the figure). When it is in the locking position, the shaded area in the figure is used for locking. The defect of this traditional structure is:

[0004] (1) The displacement conversion stroke is too large, that is: the maximum distance that the locking part can extend into the socket is only S when the manual force application stroke is H; in order to ensure convenient operation, the width of the connector in the direction of movement needs to be increased, but the increased width should not be too large.

[0005] (2) Since the plug and socket need to be locked by sound prompts when they are engaged, they must be engaged by pressing. Based on the defects in (1), the locking part needs to be pushed to move H in the direction of movement before the locking engagement can be achieved. Since H is too large, the force required to insert the socket is greater, and jamming is likely to occur in the actual process.

[0006] (3) The distance the locking part extends into the socket gradually decreases as it approaches point A, which in turn shortens the shaded area that can play a locking role. Therefore, during the locking process, its head plays the main limiting role, and it is easy to wear out and break over a long period of time.

[0007] Therefore, the present invention develops a connector with a locking mechanism to solve the problems existing in the prior art. Summary of the Invention

[0008] The purpose of this invention is to provide a connector with a locking mechanism to solve the problems of inconvenient operation and easy wear and breakage caused by unreasonable displacement direction design of the locking mechanism in the prior art.

[0009] The technical solution of this invention is: a connector with a locking mechanism, comprising:

[0010] A plug and a socket, wherein the plug has a socket and the end of the socket is inserted into the socket;

[0011] A locking mechanism is provided inside the plug, including a locking member and an actuating element. The actuating element drives the locking member to move radially along the socket, and causes the end of the locking member to enter or disengage from the socket, thereby locking or disengaging the plug and socket.

[0012] Preferably, the locking component has a locking position and an unlocking position;

[0013] The actuating element includes an elastic element that keeps the locking member in a locked position under normal conditions, and a toggle element that drives the locking member to move from the locked position to the unlocked position against the elastic force of the elastic element; the toggle element causes the locking member to be displaced by rotation.

[0014] Preferably, the elastic element is a compression spring, and the extension and retraction direction of the compression spring is the same as the movement direction of the locking element;

[0015] The actuating component includes a cam rod and a paddle. The central axis of the cam rod is perpendicular to the movement direction of the locking component and has an abutting end face with the locking component. The cam rod drives the locking component to translate through its own rotational motion. The paddle is fixedly connected to the cam rod and is located outside the plug for external force to be applied.

[0016] Preferably, the locking member has a first notch, and the first notch has a first end face perpendicular to the direction of movement of the locking member; the cam rod has a second notch, and the second notch has a second end face that abuts against the first end face in normal operation; the cam rod rotates on a fixed axis, and the end of the second end face away from the central axis of the cam rod is a cam shift point, which applies force to the first end face and pushes the locking member to move against the elastic force of the compression spring.

[0017] Preferably, the second notch on the outer wall of the cam rod has an extension block, which extends the first end face and allows the central axis of the compression spring to pass through the first end face. The cam shift point is located at the end of the extension block away from the central axis of the cam rod. The cam rod is driven by the shifter to rotate 20° to 25°, causing the locking member to disengage from the connector.

[0018] Preferably, the side wall of the connector has a slot for inserting the end of the locking member. The locking member passes through the slot and extends into the connector in normal condition. The portion protruding from the slot has a supporting surface and a guide slope. The guide slope is biased toward the side of the connector for insertion.

[0019] The socket has a stepped surface protruding from one end of the insertion port. In the locked state, the stepped surface is supported on the support surface.

[0020] Preferably, the plug includes:

[0021] The plug body has a connector, a mounting chamber, and a receiving chamber formed thereon. The connector and the mounting chamber are coaxial and the connector is arranged around the outer periphery of the mounting chamber. The receiving chamber is used to accommodate a locking mechanism, and a top cover confines the locking mechanism within the receiving chamber.

[0022] The female terminal housing is inserted into the mounting cavity, and a wire spring, a wire spring retaining ring, and a wire spring positioning ring are installed on the inner wall.

[0023] A copper lug is embedded in the plug body and connects the cable to the female terminal housing, wherein one end of the connecting cable extends out of the plug body.

[0024] A cable waterproof ring is fitted onto the outer side of the end where the copper lug connects to the cable.

[0025] The plug nut is fitted onto the outside of the cable waterproof ring and is threadedly connected to the plug body, with a sealing ring at the connection point; the inner wall of the tail of the plug nut is tapered, which tightens the end of the cable waterproof ring as it gradually engages with the threads of the plug body.

[0026] Preferably, the inner wall of the accommodating cavity has a pair of first protruding ridges, the pair of first protruding ridges are arranged parallel to each other along the movement direction of the locking member, and the locking member and the compression spring are disposed between the pair of first protruding ridges;

[0027] The inner end of the upper cover has a second protruding ridge, which is arranged along the movement direction of the locking member and is used to support the compression spring.

[0028] The fixed-axis rotating cam rod is located between the first convex ridge and the second convex ridge, and both the first convex ridge and the second convex ridge are provided with grooves for the cam rod to be accommodated and rotate.

[0029] Preferably, the outer wall of the plug body corresponding to the accommodating chamber has an opening, and the cam rod passes through the opening and is disposed between the grooves of the first convex ridge and the second convex ridge;

[0030] The end of the cam rod away from the paddle has a limiting groove, and the first protruding ridge away from the orifice has a limiting ridge. The limiting groove and the limiting ridge cooperate to prevent the protruding ridge rod from displacing axially.

[0031] Preferably, the socket includes:

[0032] Socket body;

[0033] The male terminal body is fixed to the socket body, and its end is inserted into the female terminal housing and contacts the wire spring to realize power transmission.

[0034] An anti-electric shock core is fixed to the end of the male terminal body and inserted into the female terminal housing to prevent the risk of electric shock caused by accidental contact with electronic components by fingers.

[0035] The foolproof core is fixed to the end of the socket body and inserted into the socket. The stepped surface is provided at the end of the foolproof core to play a locking role.

[0036] Compared with the prior art, the advantages of the present invention are:

[0037] (1) The locking mechanism moves radially along the connector, which can make the end of the locking part fully lock and avoid the phenomenon of local support and breakage.

[0038] (2) The fixed-axis rotational motion of the cam rod is converted into the translational motion of the locking element. The rotation angle is small and the execution is convenient. The spatial layout is not affected by the action of the actuator.

[0039] (3) When the plug and socket are connected, the applied external force only needs to overcome the elastic force of the elastic element and make the locking element move a short distance along the radial direction of the socket. The force is reasonable and the operation is convenient. Attached Figure Description

[0066] The present invention will be further described in detail below with reference to specific embodiments:

[0067] like Figure 2 , Figure 3 As shown, a connector with a locking mechanism 3 includes a plug 1, a socket 2, and a locking mechanism 3 for connecting the plug 1 and the socket 2.

[0068] Regarding plug 1, as follows Figure 4 As shown, it includes a plug body 11, a female terminal housing 12, a copper lug 13, a cable waterproof ring 14, and a plug nut 15.

[0069] like Figure 4-6 As shown, the plug body 11 has a socket 111, a mounting chamber 112, and a receiving chamber 113. The socket 111 is coaxial with the mounting chamber 112, and the socket 111 is arranged around the periphery of the mounting chamber 112. The receiving chamber 113 accommodates the locking mechanism 3, and a top cover 19 confines the locking mechanism 3 within the receiving chamber 113. The end face of the plug body 11 opposite to the socket 111 and the mounting chamber 112 has several serrations 115 for anti-slip purposes. The end face profile of the serrations 115 is low in the middle and high at the outside, similar to the profile of a thumb, which conforms to ergonomic design. Figure 2 As shown, the outer wall of the plug body 11, which is opposite to the socket 111 and the mounting chamber 112, has several ribs 1151, which can not only strengthen the body but also prevent slipping.

[0070] like Figure 4 As shown, the female terminal housing 12 is inserted into the mounting chamber 112, and the root for connecting with the copper lug 13 is in the shape of a hobbing tooth; the inner wall has a limiting step, and is equipped with a spring retaining ring 16, a spring retaining ring 17, and a spring positioning ring 18; wherein, the spring 16 is limited between the spring positioning ring 18 and the limiting step, thereby achieving precise positioning, while the spring positioning ring 18 is precisely positioned by the locking process of the head of the female terminal housing 12; the spring retaining ring 17 passes through the spring 16 to prevent the spring 16 from tilting.

[0071] like Figure 4 As shown, the copper lug 13 is embedded in the plug body 11 and is used to connect the cable to the female terminal housing 12. Therefore, the toothed shape at the root of the female terminal housing 12 needs to be pressed into the copper lug 13 by force to complete the fixation and connection. One end of the copper lug 13 that connects to the cable extends outward to the outside of the plug body 11. It has a cylindrical structure to accommodate the cable, and the central axis is perpendicular to the axis of the connector 111.

[0072] like Figure 4 As shown, the cable waterproof ring 14 is fitted on the outside of the end of the copper lug 13 that is connected to the cable, and its length along the central axis is greater than the length of the copper lug 13 extending to the outside of the plug body 11. After the cable waterproof ring 14 is compressed by the pressure of the plug nut 15, it tightens the cable and plays a waterproof role.

[0073] like Figure 4 As shown, the plug nut 15 is fitted on the outside of the cable waterproof ring 14 and is threadedly connected to the plug body 11. A sealing ring is provided at the connection point to provide waterproofing between the plug body 11 and the plug nut 15. The inner wall of the tail of the plug nut 15 is tapered, which tightens the end of the cable waterproof ring 14 as it gradually engages with the thread of the plug body 11.

[0074] Regarding socket 2, as follows Figure 3 , Figure 7 As shown, the end is inserted into the socket 111, and its structure includes a socket body 21, a male terminal body 22, an anti-electric shock core 23, and an anti-foolproof core 24.

[0075] The socket body 21 is used to achieve a fixed connection with the device. After being assembled onto the device, it has a waterproof gasket 211 between it and the device, which can effectively prevent water leakage.

[0076] The male terminal body 22 is fixed to the socket body 21, and its end is inserted into the female terminal housing 12 and contacts the wire spring 16 to realize power transmission.

[0077] The anti-electric shock core 23 is fixed to the end of the male terminal body 22 and inserted into the female terminal housing 12 to prevent the risk of electric shock caused by accidental contact with electronic components by fingers.

[0078] The foolproof core 24 is fixed to the end of the socket body 21 and inserted into the socket 111. The end is provided with a stepped surface 241, which is used to cooperate with the locking mechanism 3 to lock the socket 2 and the plug 1. The foolproof core 24 can both prevent the installation error between the male terminal body 22 and the female terminal shell 12 and realize the locking connection.

[0079] Regarding locking mechanism 3, such as Figure 3 , Figure 8As shown, the locking mechanism 3 is disposed inside the plug 1, including a locking element 31 and an actuating element, such as... Figure 9 , Figure 11 As shown, the actuator drives the locking member 31 to move radially along the connector 111, causing the end of the locking member 31 to enter or disengage from the connector 111, thus corresponding to a locking position and an unlocking position, thereby realizing the locking or disengagement of the plug 1 and the socket 2. In conjunction with... Figure 15 As shown, after the locking mechanism 3 is installed, the corresponding connector 111 side wall has a slot 117 for the end of the locking member 31 to be inserted. Under normal conditions, the locking member 31 passes through the slot 117 and extends into the connector 111, at which time it is in the locking position. When the locking member 31 retracts into the slot 117, it is in the unlocking position.

[0080] The actuating element includes an elastic element 32 that keeps the locking member 31 in the locked position under normal conditions, and an actuating element 33 that drives the locking member 31 to move from the locked position to the unlocked position against the elastic force of the elastic element 32; in this embodiment, the elastic element 32 is a compression spring 321, and the extension and retraction direction of the compression spring 321 is the same as the movement direction of the locking member 31; such as Figure 12 As shown, the actuating member 33 includes a cam rod 331 and a paddle 332. The central axis of the cam rod 331 is perpendicular to the movement direction of the locking member 31 and has an abutting end face with the locking member 31. It drives the locking member 31 to translate through its own rotational movement. The paddle 332 is fixedly connected to the cam rod 331 and is located outside the plug 1 for external force to be applied.

[0081] Specifically, such as Figure 13 , 14 As shown, the locking member 31 has a support surface 311 and a guide slope 312 on the part protruding from the slot 117. The support surface 311 supports the stepped surface 241 of the anti-foolproof core 24, and the guide slope 312 is biased towards the side of the socket 111 for the insertion of the socket 2. The locking member 31 has a first notch 313, and the first notch 313 has a first end face 314 perpendicular to the direction of movement of the locking member 31; the cam rod 331 has a second notch 333, and the second notch 333 has a second end face 334 that abuts against the first end face 314 under normal conditions; when the cam rod 331 rotates on a fixed axis, the end of the second end face 334 away from the central axis of the cam rod 331 is the cam setting point, that is... Figure 14 At point B, the cam applies force to the first end face 314 and pushes the locking member 31 to move against the elastic force of the compression spring 321.

[0082] like Figure 14As shown, the distance between the central axis of the cam rod 331 and the cam release point is set to L. The angle of rotation required by the cam rod 331 to move the locking member from the locking position to the unlocking position is θ, and the distance the locking member 31 moves is D. Then, D = L * sinθ is satisfied. To facilitate operation and the reset of the cam rod 331, the rotation angle θ should not be too large. When D is a constant value, the smaller θ is, the larger the corresponding L is. Therefore, as a further optimization of this embodiment, the outer wall of the cam rod 331 is... The second notch 333 has an extension block 335, which extends the first end face 314 and allows the central axis of the compression spring 321 to pass through the first end face 314. The cam shift point is located at the end of the extension block 335 away from the central axis of the cam rod 331, thereby increasing L. The cam rod 331 is driven by the shift piece 332 to rotate 20° to 25°, which can disengage the locking member 31 from the connector 111. At this rotation angle, the reset of the cam rod 331 is also very easy.

[0083] Combination Figure 15 As shown, after with Figure 1 In comparison, it can be seen that the radial movement of the locking member 31 along the connector 111 through point A in this invention can enable the entire end of the locking member 31 to play a locking role. That is, the shaded area at the end of the locking member 31 can be used entirely for support, avoiding the phenomenon of breakage due to partial support. Furthermore, when the plug 1 and the socket 2 are connected and mated, the applied external force only needs to overcome the elastic force of the compression spring 321, so that the locking member 31 can be displaced a short distance radially along the connector 111. The force application is reasonable and the operation is convenient.

[0084] In this embodiment, the locking mechanism 3 is installed inside the accommodating chamber 113. The installation must ensure that the cam rod 331 is limited in both the axial and radial directions, and is only used for fixed-axis rotation. Therefore, considering the structure of the accommodating chamber 113, the radial limiting design of the cam rod 331 is as follows:

[0085] like Figure 6 , Figure 16 As shown, the inner wall of the accommodating chamber 113 has a pair of first protruding ridges 116, which are arranged parallel to the movement direction of the locking member 31. The locking member 31 and the compression spring 321 are disposed between the pair of first protruding ridges 116. The corresponding side wall of the accommodating chamber 113 has a slot 117 communicating with the insertion port 111. The inner end of the upper cover 19 has a second protruding ridge 191, which is arranged along the movement direction of the locking member 31 and is used to support the compression spring 321. The fixed-axis rotating cam rod 331 is limited between the first protruding ridge 116 and the second protruding ridge 191. Both the first protruding ridge 116 and the second protruding ridge 191 are provided with grooves for the cam rod 331 to be accommodated and rotate. Figure 6As shown, the outer wall of the plug body 11 corresponding to the accommodating chamber 113 has an opening 114. The cam rod 331 passes through the opening 114 and is positioned between the grooves of the first protrusion 116 and the second protrusion 191, thereby achieving radial positioning of the cam rod 331. Regarding the design of the opening 114, as follows... Figure 2 As shown, the outer wall of the plug body 11 corresponding to the opening 114 has an annular part, and the annular part has a notch for the paddle 332 to be accommodated and rotated. Thus, when unlocking, the user only needs to move the paddle 332 within the notch range.

[0086] The axial limit of cam rod 331 is as follows:

[0087] like Figure 12 As shown, the end of the cam rod 331 away from the paddle 332 has a limiting groove 336, such as... Figure 6 As shown, the first protruding ridge 116 away from the orifice 114 has a limiting ridge 1161, and the limiting groove 336 cooperates with the limiting ridge 1161 to prevent the cam rod 331 from being displaced along the axial direction.

[0088] The specific working principle is as follows:

[0089] (1) In the unassembled state, such as Figure 2 As shown, plug 1 and socket 2 are in a separated state, and at this time the locking mechanism 3 is in the locking position inside plug 1;

[0090] (2) At the start of assembly, such as Figure 10 As shown, the socket 2 is inserted into the socket 111 along the central axis. During insertion, the top of the anti-fooling core 24 abuts against the guide slope 312 at the end of the locking member 31, thereby causing the locking member 31 to gradually retract against the spring force of the compression spring 321 until the stepped surface 241 moves to one side of the support surface 311, as shown. Figure 11 The state shown; then, the locking member 31 rebounds under the elastic force of the compression spring 321, enters the locking position again, and makes a "click" sound. The locking is completed by the sound prompt function; in this state, the support surface 311 limits the step surface 241, thereby completing the cooperation between the plug 1 and the socket 2.

[0091] (3) When unlocking, move the lever 332 to cause the cam rod 331 to rotate on a fixed axis, such as Figure 11 As shown, the cam pushes the locking member 31 to retract against the elastic force of the compression spring 321 until the locking member 31 is in the unlocked position, at which point the socket 2 can be directly pulled out from the connector 111.

[0092] The above embodiments are merely illustrative of the technical concept and features of the present invention, intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and should not be construed as limiting the scope of protection of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
