Description

Technical Field

[0001] This utility model belongs to the field of electrical connectors, and particularly relates to a locking component, an electrical connector, and a connector assembly. Background Technology

[0002] In the field of electrical connections for electronic devices, electrical connectors are key components for achieving circuit conduction and signal transmission, and their performance and reliability directly affect the operation of the entire electronic system. Locking mechanisms play a crucial role in electrical connectors, ensuring a secure connection between them and preventing loosening due to external forces, vibrations, or other factors, thereby avoiding problems such as signal transmission interruptions and poor contact.

[0003] Currently, in existing related technical solutions, mounting slots need to be provided within the mating area of ​​the electrical connector housing for the installation of locking components, and the locking components of electrical connectors typically employ a structural design that places the locking points above the mounting position of the locking components. For example... Figure 14 and Figure 15 As shown, in practical applications, when it's necessary to further enhance the locking capability of the latching component, the only direct way to achieve this is by increasing the thickness of the locking point. However, increasing the locking point thickness inevitably leads to a corresponding increase in the required installation depth of the latching component, meaning the mounting groove needs to be deeper. This, in turn, causes the mounting groove to occupy the space of the circuit board within the original mating area of ​​the housing. To make enough space for the installation position of the latching component after the locking point is thickened, it is usually necessary to cut off the circuit board below the mounting groove. This operation not only increases the complexity and production cost of the circuit board manufacturing process, but more importantly, it greatly restricts the wiring design of the circuit board, seriously affecting the electrical performance and overall layout rationality of the circuit board, which is detrimental to the development of electronic devices towards miniaturization, high performance, and high integration. Summary of the Invention

[0004] The purpose of this invention is to provide a locking component, an electrical connector, and a connector assembly to overcome at least one of the aforementioned defects in the prior art.

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

The pressing end of the pressing part is located above the elastic support part, and the front end of the pressing part extends forward and is provided with a hook. The rotating fulcrum is located between the hook and the pressing end of the pressing part, so that pressing the pressing end of the pressing part drives the hook to rotate around the rotating fulcrum.

[0016] Preferably, the upper side of the support section has an arc surface.

[0017] Preferably, the fixed section has a through hole, and the through hole has an elastic sheet that bends downward from the sidewall of the through hole away from the bending section.

[0018] Preferably, the fixed section has protruding clamping sections on both the left and right sides.

[0019] Preferably, the elastic support, the rotating fulcrum, and the pressing part are provided together.

[0020] This utility model provides an electrical connector, including at least one of the above-described locking elements.

[0021] Preferably, the device further includes a housing having a mating area, a locking element installed on the housing, and the locking element being installed at the rear side of the mating area, with a hook located above the mating area.

[0022] Preferably, it also includes a circuit board disposed inside the housing, a locking element disposed outside the housing, and a portion of the circuit board extending outside the housing.

[0023] Preferably, at least one side wall of the housing has a first slot, which engages with a hook and is located within the mating area.

[0024] Preferably, at least one side wall of the housing has a protruding mounting base, and the pivot point is mounted on the mounting base.

[0025] Preferably, the housing has a boss, the upper side wall of the boss has an arc-shaped groove, and the pressing part has a transition section that mates with the arc-shaped groove.

[0026] Preferably, at least one side wall of the housing has a mounting groove, and the elastic support is mounted in the mounting groove, which is located on the rear side of the mating area.

[0027] Preferably, the elastic support includes a fixed section, a bent section, an inclined arm, and a support section. The fixed section is installed in the mounting groove, and the inclined arm is connected to the fixed section through the bent section. The fixed section has a through hole, and an elastic piece is bent downward from the side wall of the through hole away from the bent section. The lower side wall of the mounting groove has a second groove that mates with the elastic piece.

[0028] Preferably, the left and right sides of the fixing section have protruding clamping sections, and the left and right sides of the mounting groove have third grooves that cooperate with the clamping sections.

[0029] Preferably, the circuit board has a first mating end and a second mating end, wherein the mating direction of the first mating end is perpendicular to the mating direction of the second mating end.

[0030] Preferably, it further includes a conductive terminal group, which is disposed in the housing and electrically connected to the second mating end.

[0031] This utility model also provides a connector assembly, including the above-mentioned electrical connector and a mating connector that mates with the electrical connector.

[0032] Preferably, the mating connector has a locking hole that mates with the locking hook.

[0033] The beneficial effects of this utility model are as follows:

[0034] 1. By extending the pressing part forward and setting the hook on the forward-extending part of the pressing part. The hook, as a structure that mates with the locking hole of the mating connector, is set at the front end of the pressing part, rather than the top end of the pressing part. This makes it possible to move the mounting position of the locking component backward even if the thickness of the hook is increased, because the hook and the pressing end of the pressing part are set in front of and behind each other. There is no circuit board in the housing at the mounting position, so there is no need to cut off the circuit board.

[0035] 2. The hook design allows the connector to be inserted into the locking hole of the mating connector from the outside during mating, thus achieving connection between the electrical connector and the mating connector. This provides a locking method completely opposite to traditional locking mechanisms.

[0036] 3. The guide end guides the connector during docking, and the stop surface engages with the rear side wall of the connector's locking hole to achieve positioning.

[0037] 4. When the pivot point is above the pressing part, the pivot point limits the transition section and acts as a pivot point, causing the extension arm to tilt upward, thereby driving the hook to move upward away from the locking hole of the docking connector, thus realizing the unlocking operation.

[0038] 5. The smooth transition between the curved surface and the bottom surface of the pressing arm makes pressing the pressing arm smoother.

[0039] 6. The fixed section is limited and fixed by the cooperation of the elastic sheet and the clamping section with the shell.

[0040] 7. The locking mechanism is divided into three parts, changing the traditional one-piece design. When one part of the locking mechanism is damaged, it is no longer necessary to replace the entire mechanism as with traditional one-piece locking mechanisms; only the damaged part needs to be replaced, which greatly reduces maintenance costs. Each of the three parts can be designed as a standardized component. This means that in different application scenarios, as long as the specifications of each part match, these components can be interchanged. This improves the versatility of the locking mechanism and reduces the complexity and cost of designing multiple locking mechanisms for different equipment requirements.

[0041] 8. This design fundamentally avoids the problem of the locking mechanism's installation position occupying space on the circuit board within the mating area of ​​the housing. This improved design eliminates the need to cut off the circuit board below the hook without changing the original overall circuit board layout, thus providing more space and greater freedom for circuit board wiring design.

[0042] 9. The first slot design allows the hook to extend a certain distance after passing through the connector's hole, improving the docking stability of the connector assembly.

[0043] 10. By installing the pivot point on the upper side wall of the housing, the space outside the housing is fully utilized, avoiding excessive space occupation inside the housing. This helps to optimize the spatial layout of the entire product and makes the product structure more compact.

[0044] 11. The transition section and the arc-shaped groove work together to make the extension arm rise more smoothly when the pressing arm is pressed, and the same applies to the reset.

[0045] 12. Locking fasteners are provided at the top and bottom of the housing to make the connection between the electrical connector and the mating connector more stable. Attached Figure Description

Detailed Implementation

[0062] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

Furthermore, terms such as "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0064] Example 1:

[0065] like Figures 1 to 3As shown, this embodiment provides a locking component including an elastic support 1, a rotation fulcrum 2, and a pressing part 3. The pressing end of the pressing part 3 is located above the elastic support 1. The front end of the pressing part 3 extends forward and is provided with a hook 34. The rotation fulcrum 2 is located between the hook 34 and the pressing end of the pressing part 3, so that pressing the pressing end of the pressing part 3 causes the hook 34 to rotate around the rotation fulcrum 2. By extending the pressing part 3 forward and providing the hook 34 in the forward-extending portion of the pressing part 3, the hook 34, as a structure that mates with the locking hole 71 of the mating connector, is located at the front end of the pressing part 3, rather than at the top end. This allows the locking component to be installed further back even if the hook thickness is increased, because the hook 34 and the pressing end of the pressing part 3 are positioned in a front-back manner, the installation position of the locking component is shifted backward. There is no circuit board 5 inside the housing 4 at the installation position, eliminating the need to cut off the circuit board 5. In this embodiment, the rotation fulcrum 2 is a pin, located above the pressing part 3. Specifically, the pressing part 3 includes a transition section 31, an extension arm 32, and a pressing arm 33. The extension arm 32 and the pressing arm 33 are connected by the transition section 31. A hook 34 is disposed on the extension arm 32. The pressing arm 33 is located above the elastic support part 1. The transition section 31 is arc-shaped, and its concave surface faces the rotation fulcrum 2. When unlocking, pressing down on the pressing arm 33 limits the transition section 31 through the rotation fulcrum 2, which also acts as a fulcrum, causing the extension arm 32 to tilt upward. This, in turn, causes the hook 34 to move upward away from the locking hole 71 of the docking connector 7, thus achieving the unlocking operation.

[0066] The upper side of the pressing arm 33 has several anti-slip protrusions 331. The anti-slip protrusions 331 facilitate finger pressing to unlock.

[0067] The hook 34 extends downward from the left and right side walls of the pressing part 3. This arrangement, when mating with the connector 7, allows the hook 34 to extend from the outside of the connector 7 and hook into the locking hole 71 of the connector 7, thus achieving connection between the electrical connector and the connector 7. This provides a locking method completely opposite to conventional locking mechanisms. Conventional locking mechanisms use a locking point that extends from the inside of the connector 7 and hooks into the locking hole 71 of the connector 7.

[0068] The front end of the hook 34 is a guide end 341 for insertion, and the rear end is a stop surface 342. The guide end 341 guides the hook when it is inserted into the connector 7, and the stop surface 342 engages with the rear side wall of the locking hole 71 of the connector 7 for stopping.

[0069] The elastic support 1 includes a fixed section 11, a bent section 12, a slanted arm 13, and a support section 14. The fixed section 11 is mounted on the housing 4. The slanted arm 13 is connected to the fixed section 11 via the bent section 12, and the end of the slanted arm 13 is connected to the support section 14. The bent section 12 provides deformation capability to the slanted arm 13, ensuring that the support section 14 always abuts against the pressing arm 33. When locked, it ensures that the hook 34 is always engaged in the locking hole 71 of the mating connector 7, ensuring mating stability. Furthermore, it allows the pressing arm 33 to be pressed when unlocking.

[0070] The upper side of the support section 14 has an arc surface 141. By cooperating with the bottom surface of the pressing arm 33, a smooth transition can be achieved, making the pressing of the pressing arm 33 smoother.

[0071] The fixing section 11 has a through hole 111, and an elastic piece 112 bends backward and downward from the side wall of the through hole 111. Both the left and right sides of the fixing section 11 have protruding clamping sections 113. The fixing section 11 is limited and fixed by the cooperation of the elastic piece 112 and the clamping section 113 with the housing 4.

[0072] The locking mechanism is divided into three separate parts: the elastic support 1, the rotating fulcrum 2, and the pressing part 3. This design departs from the traditional one-piece locking mechanism. When any part of the locking mechanism is damaged, it no longer requires replacement of the entire mechanism as with traditional one-piece locking mechanisms; only the damaged part needs to be replaced, significantly reducing maintenance costs. Each of the three parts can be designed as a standardized component. This means that in different application scenarios, as long as the specifications of each part match, these components can be interchanged. This improves the versatility of the locking mechanism and reduces the complexity and cost of designing multiple locking mechanisms to meet different equipment requirements.

[0073] Example 2:

[0074] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that:

[0075] Rotation fulcrum 2 is fixed on both the left and right side walls of the pressing part 3, and the rotation fulcrum 2 is rotatably connected to the housing 4. This provides another way to drive the hook 34 to rotate around the rotation fulcrum 2 after pressing the pressing end of the pressing part 3.

[0076] Example 3:

[0077] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that:

[0078] The pivot point 2 passes through the pressing part 3, and its left and right ends are located on the left and right sides of the pressing part 3, respectively. Both ends of the pivot point 2 are rotatably connected to the housing 4. This provides another way to drive the hook 34 to rotate around the pivot point 2 after pressing the pressing end of the pressing part 3.

[0079] Example 4:

[0080] like Figures 6 to 11 As shown, this embodiment provides an electrical connector, including a locking member (as in Embodiment 1), a housing 4, and a circuit board 5. The housing 4 has a mating area 8. The locking member is disposed outside the housing 4, and its mounting position is located behind the mating area 8. A hook 34 is located above the mating area. The circuit board 5 is disposed inside the housing 4, with a portion of the circuit board 5 extending outside the housing 4. In this embodiment, the locking member is disposed at the top of the housing 4.

[0081] This fundamentally avoids the problem of the locking fastener's installation position occupying space on the circuit board 5 within the mating area 8 inside the housing 4. This improved design allows for the elimination of the need to cut off the circuit board 5 below the hook 34 without changing the overall layout of the original circuit board 5, thus providing more space and greater freedom for the wiring design of the circuit board 5.

[0082] The upper sidewall of the housing 4 has two first slots 41, which engage with two hooks 34. Both first slots 41 are located within the mating area 8. In this embodiment, the first slots 41 are located below the hooks 34. The first slots 41 allow the hooks 34 to extend a further distance after passing through the locking holes 71 of the mating connector 7, thus improving the mating stability of the connector assembly.

[0083] The upper sidewall of the housing 4 has two protruding mounting seats 42, one on the left and one on the right. The left and right ends of the rotating fulcrum 2 are respectively inserted into the two mounting seats 42. By setting the mounting seats 42, the rotating fulcrum 2 is installed on the upper sidewall of the housing 4. Installing the rotating fulcrum 2 on the upper sidewall of the housing 4 makes full use of the space outside the housing 4 and avoids occupying too much space inside the housing 4, which helps to optimize the spatial layout of the entire product and makes the product structure more compact.

[0084] The housing 4 between the two mounting seats 42 has a boss 43, and the upper side wall of the boss 43 has an arc-shaped groove 431. The rotation fulcrum 2 is located above the pressing part 3. The pressing part 3 has a transition section 31, which cooperates with the arc-shaped groove 431. Through the cooperation between the transition section 31 and the arc-shaped groove 431, the extension arm 32 can be raised more smoothly when the pressing arm 33 is pressed, and the same applies to the reset.

[0085] The upper sidewall of the housing 4 has a mounting groove 44, and the elastic support part 1 is mounted in the mounting groove 44, which is located behind the docking area 8. The elastic support part 1 includes a fixing section 11, a bending section 12, an inclined arm 13, and a support section 14. The fixing section 11 is mounted in the mounting groove 44, and the inclined arm 13 is connected to the fixing section 11 via the bending section 12. The fixing section 11 has a through hole 111, and an elastic piece 112 bends backward and downward from the sidewall of the through hole 111 within the through hole 111. The lower sidewall of the mounting groove 44 has a second locking groove 45 that mates with the elastic piece 112. The left and right sides of the fixing section 11 have protruding locking sections 113, and the left and right sides of the mounting groove 44 have third locking grooves 46 that mate with the locking sections 113. During installation, align the locking section 113 and the third slot 46, and insert the elastic support 1 backward and forward into the mounting slot 44. The third slot 46 engages with the locking section 113, and the elastic piece 112 engages with the second slot 45, thus stably mounting the elastic support 1 onto the housing 4. By positioning the mounting slot 44 on the rear side of the mating area 8, even if the mounting slot 44 is made deeper, it has no impact, because there is no circuit board inside the housing below it, therefore no additional circuit board removal is required.

[0086] The circuit board 5 has a first mating end 51 and a second mating end 52, with the mating direction of the first mating end 51 perpendicular to the mating direction of the second mating end 52. This arrangement optimizes the wiring and makes the arrangement more compact.

[0087] It also includes a conductive terminal group 6, which is disposed in the housing 4 and electrically connected to the second mating end 52, and the first mating end 51 is mated to the mating connector 7.

[0088] Example 5:

[0089] like Figure 12 As shown, the difference between this embodiment and Embodiment 4 is that:

[0090] In this embodiment, the top and bottom of the housing 4 are provided with locking fasteners, which makes the connection between the electrical connector and the mating connector 7 more stable.

[0091] Example 6:

[0092] like Figure 13 As shown, this embodiment provides a connector assembly, including the electrical connector of Embodiment 4 and a mating connector 7 that mates with the electrical connector.

[0093] The mating connector 7 has a locking hole 71 that mates with the hook 34. By combining the position of the hook 34 with the structure of the locking element, a locking mechanism is formed in which the hook extends from the outside of the locking hole 71 and hooks onto the element.

[0094] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
