Description

TECHNICAL FIELD

[0001] The utility model relates to the connecting equipment of electronic device, especially point out an easy to disassemble with locking function electronic connector. BACKGROUND

[0002] In modern life, electrical products are widely used in homes, offices and industrial fields, and these electrical appliances are usually connected to the power supply through plugs and sockets to obtain the required power. The design of the plug and socket allows the electrical equipment to be quickly and conveniently connected or disconnected, providing flexibility for users. However, this connection method also has some problems that affect the stability and safety of use.

[0003] In the past, the connection between the plug and the socket mainly relied on friction to maintain fixation, but due to the limitations of this mechanical fixation method, it was easy to come loose or fall off due to external forces, resulting in the following problems: (1) accidental power failure: when the plug is loosened due to accidental touch or kicking, the connected electrical equipment will suddenly lose power, which may result in data loss (such as computer equipment), mechanical stop (such as industrial machinery), or other abnormal functions. (2) Poor contact and arc problem: If the plug and socket are not in complete contact, it may cause unstable current or generate arc, which may affect the operation of the equipment, and even increase the risk of fire. (3) Mechanical damage: Frequent plugging and unplugging or mechanical fatigue caused by pulling may damage the plug or socket, making it unable to be securely connected, thereby shortening its service life. (4) Safety hazards: When the plug is not fully inserted or the socket is loose, the exposed metal contacts may increase the risk of electric shock, posing a potential threat to users.

[0004] In order to solve the above problems, many improvement schemes have been introduced in recent years, such as using screws to fix the plug and socket together to improve the stability and safety of the plug and socket. However, the current locking structure has the problem of being difficult to separate, which results in an increase in the difficulty of disassembly while improving the safety of electrical connection, thereby causing inconvenience in use.

[0005] Therefore, how to provide an electronic connector structure that can effectively improve the locking strength of electronic equipment connection and can be easily disassembled is one of the urgent problems to be solved by researchers and developers in the relevant field. INVENTION CONTENTS

[0007] To achieve the aforementioned utility model objective, this utility model provides an electronic connector with a locking function, which is a second connector used to couple a first connector having a first terminal. The second connector includes: a base with a second terminal disposed inside; an adjusting housing movably fitted onto the base; and a locking member mounted on the base, with a portion of the locking member protruding at an angle between the second terminal and the adjusting housing. The first terminal passes through the adjusting housing and the locking member and is coupled to the second terminal within the base, with the second terminal providing a first restraint on the first terminal. The engaging member provides a second binding force to the terminal; wherein, when the first connector and the second connector are coupled, pulling the first connector in one direction restricts the first connector under the first binding force and the second binding force, preventing it from detaching from the second connector; wherein, when the first connector and the adjusting housing are coupled in both directions, pulling the first connector and the adjusting housing synchronously under opposite forces causes the adjusting housing to release the second binding force in conjunction with the engaging member, and causes the first connector to detach from the first binding force and thus detach from the second connector.

[0008] In one embodiment, the engaging element is a spring piece with a certain elasticity and generally U-shaped, with a fixing section and an engaging section at each end, and the fixing section and the engaging section are at an angle between 90 degrees and 180 degrees under normal conditions.

[0010] In one embodiment, the adjusting housing has a pressing surface formed at the front end of the base; when the adjusting housing moves away from the first connector, the pressing surface presses against the engaging segment of the engaging member, causing the engaging segment to rotate toward the second connector.

[0011] In one embodiment, the base has an extension on one side of the inner insertion hole that extends toward the pressing surface of the adjusting housing, so that when the adjusting housing moves a certain distance toward the second connector, it abuts against the extension to prevent the adjusting housing from continuing to move.

[0012] In one embodiment, the pressing surface of the adjusting housing has two limiting portions located on opposite sides of the extension; and a limiting groove is formed between the two limiting portions and corresponds to the extension.

[0013] In one embodiment, the fixed section has a protrusion on each of its opposite sides; the base has an inwardly recessed positioning groove inside, so that when the fixed section of the engaging member extends into the base, the plurality of protrusions engage in the positioning groove.

[0014] In one embodiment, the outer peripheral surfaces of the second connector on opposite sides are respectively formed with an inclined flange; the inner wall surfaces of the adjusting housing on opposite sides are respectively provided with an inclined groove for accommodating the flange on the same side.

[0015] In one embodiment, the first connector further has a hollow fitting portion surrounding the plurality of the first terminals, and the shape of the fitting portion corresponds to the shape of the adjustment housing.

[0016] In one embodiment, an electronic connector with a locking function includes: a first connector having a body and a plurality of first terminals; the plurality of first terminals being disposed on one side of the body and extending away from the body; a second connector having a base and a plurality of second terminals; the base having a plurality of accommodating spaces inside, and a plurality of internal insertion holes on one side communicating with the accommodating spaces; the plurality of second terminals being disposed in the plurality of accommodating spaces of the base and corresponding to at least a portion of the plurality of internal insertion holes; and a locking mechanism having an adjusting housing and a plurality of engaging members; the adjusting housing being sleeved on the second connector and having a plurality of external insertion holes corresponding to the plurality of internal insertion holes of the base; each engaging member being disposed within the base. One end has a locking section located between the base and the adjusting housing. The locking section has a locking hole corresponding to the inner insertion hole and the outer insertion hole in the same axial direction. The first connector is connected to the second connector. A plurality of the first terminals pass through a plurality of the outer insertion holes, a plurality of the locking holes, and a plurality of the inner insertion holes. The edges of the plurality of locking holes abut against the plurality of the first terminals, so that the first connector and the second connector are bound together by the friction between the plurality of locking members and the plurality of the first terminals. When the adjusting housing moves away from the first connector, the adjusting housing acts on the plurality of locking sections so that the edges of the plurality of locking holes do not abut against the plurality of the first terminals, thereby releasing the first connector and the second connector from the bound state.

[0028] Please see Figures 1 to 3 As shown, the electronic connector with locking function provided in a preferred embodiment of the present invention mainly includes a first connector 10, a second connector 20 and a locking mechanism 30.

[0029] in:

[0030] The first connector 10 has a body 11 and a plurality of first terminals 12. The plurality of first terminals 12 are connected to one side of the body 11 and extend in a direction away from the body 11. In this embodiment, the first connector 10 is a three-prong plug with three first terminals 12, each including a live wire terminal, a neutral wire terminal, and a ground wire terminal. In addition, the first connector 10 further has an annular fitting portion 13, which is disposed at one end of the plurality of first terminals 12 adjacent to the body 11, and a fitting space 14 is formed inside, so that the plurality of first terminals 12 are surrounded within the fitting space 14 of the fitting portion 13.

[0031] The second connector 20 has a base 21 and a plurality of second terminals 22. The base 21 has a plurality of accommodating spaces 210 inside, and a plurality of positioning grooves 211 formed on the inner wall surface of the plurality of accommodating spaces 210 and recessed inward. One end of the base 21 has a plurality of internal insertion holes 212 respectively communicating with the plurality of accommodating spaces 210. The number and position of the plurality of internal insertion holes 212 correspond to the number and position of the plurality of first terminals 12 of the first connector 10. On the side of the base 212 where the plurality of internal insertion holes 212 are located, two extensions 213 are provided, spaced a certain distance apart and extending away from the base 21. Two inclined flanges 214 are formed on the outer peripheral surfaces of opposite sides of the base 21. The plurality of second terminals 22 are respectively disposed in the plurality of accommodating spaces 210 and correspond to two of the internal insertion holes 212. The plurality of second terminals 22 are used to engage with the plurality of first terminals 12 to energize the first connector 10 and the second connector 20. In this embodiment, each of the second terminals 22 is a metal clip that is generally U-shaped and relatively wide, with a central groove 220 for clamping the live wire terminal and the neutral wire terminal when the first connector 10 is inserted into the second connector 20.

[0032] The locking mechanism 30 is disposed on the second connector 20 and is used to switch the second connector 20 and the first connector 10 between a locked state and an unlocked state. In this embodiment, the locking mechanism 30 has an adjusting housing 31 and two engaging members 32. The adjusting housing 31 is a hollow cylindrical component, the shape of which corresponds to the shape of the base 21, and is used to fit over the outside of the base 21. The adjusting housing 31 has a pressing surface 310 formed at the front end of the base 21, and a plurality of external insertion holes 311 penetrating the pressing surface 310, the number and position of which correspond to the plurality of internal insertion holes 212 of the base 21. The pressing surface 310 is provided with a plurality of limiting portions 312. Each pair of limiting portions 312 is respectively provided on opposite sides of one of the extension portions 213 of the base 21, and a limiting groove 313 is formed between the two limiting portions 312 and corresponds to the extension portion 213. The plurality of limiting grooves 313 are used to accommodate the extension portion 213 when the adjusting housing 31 moves, and to prevent the adjusting housing 31 from moving further backward when the extension portion 213 abuts against the limiting groove 313. The two limiting portions 312 are used to position the extension portion 213. The inner wall surfaces of opposite sides of the adjusting housing 31 are each provided with an inclined groove 314 to accommodate the flange 214 on the same side.

[0033] The two locking components 32 are respectively disposed within the receiving space 210 of the second connector 20, and at least a portion of each locking component 32 is located between each second terminal 22 and the corresponding inner insertion hole 212. Each locking component 32 is a metal spring with a certain elasticity and generally U-shaped, having a fixed section 320, a locking section 321, and a locking hole 322 connected together. The fixed section 320 is fixed within one of the receiving spaces 210 of the base 21, generally parallel to the plurality of second terminals 22. The fixed section 320 has two protrusions 320a on opposite sides, corresponding to one of the positioning grooves 211, so that when the fixed section 320 of the locking component 32 extends into the base 21, the plurality of protrusions 320a engage in the positioning groove 211. One end of the engaging section 321 is connected to the fixed section 320, and the other end extends between the base 21 and the adjusting housing 31. The engaging section 321 and the fixed section 320 are at a predetermined angle under normal conditions, so that the engaging section 321 and the second terminal 22 are not parallel. The predetermined angle is between 90 and 180 degrees. The engaging hole 322 is formed on the engaging section 321 and is parallel to it, and is aligned with the inner insertion hole 212 and the outer insertion hole 311 along the same axial direction. It is particularly important to note that since the engaging section 321, the side of the base 21 with the plurality of inner insertion holes 212, and the pressing surface 310 of the adjusting housing 31 are not parallel, the engaging hole 322 is also not parallel to the inner insertion hole 212 and the outer insertion hole 311 along the same axial direction.

[0034] Based on the above structural configuration, the electronic connector with locking function provided by this utility model has the following practical application:

[0035] When the engaging section 321 of the engaging member 32 is in an inclined state, the engaging hole 322 presents a smaller passage area for the first terminal 12 compared to when the engaging section 321 is perpendicular. In this embodiment, when the first terminal 12 is inserted along the external insertion hole 311, even if it is aligned with the engaging hole 322, it cannot immediately pass through the engaging hole 322.

[0036] However, due to the pressure exerted by the first terminal 12 attempting to insert, the engaging section 321 is pushed away from the pressing surface 310 of the adjusting housing 31, causing the engaging section 321 to tilt in the vertical direction. When the engaging section 321 tilts to a sufficient angle, the first terminal 12 can enter the second connector 20 through the engaging hole 322 on the engaging section 321 and fully engage with the second terminal 22 to form an energized state, such as... Figure 3 As shown.

[0037] Please see Figure 4When the first terminal 12 engages with the second terminal 22, the second terminal 22 provides a first binding force to the first terminal 12. The engaging member 32 is in a compressed state and applies an elastic force toward the adjusting housing 31, causing the engaging section 321 to tend to deflect toward the pressing surface 310. This causes the edge of the engaging hole 322 to press against the surface of the inserted first terminal 12, thereby providing a second binding force with a clamping effect. The second binding force is normally greater than the first binding force. In this case, if the first connector 10 is pulled in one direction to apply an axial pull-out force to remove it from the second connector 20, the top of the first terminal 12 cannot be moved out of the second connector 20 due to the second binding force generated by the clamping of the engaging member 32. Therefore, the bottom of the engaging section 321 of the engaging member 32 is pulled toward the front end face and rotates. However, when the engaging section 321 attempts to rotate, the edge of its engaging hole 322 clamps the inserted first terminal 12 more tightly. Therefore, the greater the pull-out force applied, the stronger the second binding force of the engaging member 32 clamping the first terminal 12, which usually prevents the first connector 10 from being removed, thereby binding it within the second connector 20 to form a binding state and achieving the locking function.

[0038] Please refer to the following: Figure 5 and Figure 6 As shown, when a user wishes to separate the first connector 10 and the second connector 20, the user can hold the first connector 10 and the adjusting housing 31 fitted on the outside of the second connector 20 with both hands, and apply force in opposite directions simultaneously. This reaction force will cause the adjusting housing 31 to be moved away from the first connector 10. In this way, the pressing surface 310 of the adjusting housing 31 will press against the plurality of engaging segments 321 of the plurality of engaging members 32 during the retraction process, compressing the engaging segments 321 in a direction perpendicular to the fixed segment 320. At this time, the passage area of ​​the engaging hole 322 on the engaging segment 321 will gradually increase as the engaging segment 321 rotates, thereby releasing the second binding force exerted by the edge of the engaging hole 322 on the first terminal 12, thus releasing the first connector 10 and the second connector 20 from their restrained state. In this way, when the multiple locking pieces 32 no longer clamp the multiple first terminals 12, the first connector 10 and the second connector 20 can be easily separated by simply pulling them in opposite directions, thus achieving easy assembly and disassembly.

[0039] Please see Figure 7As shown, the electronic connector with locking function provided in a second preferred embodiment of the present invention has a structure similar to that of the first preferred embodiment. However, in this embodiment, it is configured within an extension line structure, which has a plurality of the second connectors 20 and a plurality of the locking mechanisms 30.

[0040] Please see Figure 8 As shown, the electronic connector with locking function provided in a third preferred embodiment of this utility model has a structure similar to that of the first preferred embodiment. However, in this embodiment, the first connector 10 and the second connector 20 correspond to a US standard plug and socket, respectively. The locking mechanism 30 also corresponds to the shape and configuration of the US standard socket of the second connector 20.

[0041] Please see Figure 9 As shown, the electronic connector with locking function provided in a fourth preferred embodiment of this utility model has a structure similar to that of the first preferred embodiment. However, in this embodiment, the first connector 10 and the second connector 20 correspond to a universal standard plug and socket, respectively. The locking mechanism 30 also corresponds to the shape and configuration of the universal standard socket of the second connector 20.

[0042] Please see Figure 10 As shown, the electronic connector with locking function provided in a fifth preferred embodiment of this utility model has a structure similar to that of the first preferred embodiment. However, in this embodiment, the first connector 10 and the second connector 20 correspond to a USB plug and a USB charging head, respectively. The locking mechanism 30 also corresponds to the shape and configuration of the USB charging head of the second connector 20.

[0043] As can be seen from the above embodiments, this utility model is not limited to the general plug and socket form. The first connector 10 and the second connector 20 of any electrical connection form, after being configured with the locking mechanism 30, do not deviate from the application scope of this utility model.

[0044] In summary, the electronic connector with locking function provided by this utility model allows the first connector 10 and the second connector 20 to automatically lock together upon connection via the locking mechanism 30, effectively improving connection strength and preventing detachment of the first connector 10 and the second connector 20 due to accidental contact or external impact. Furthermore, the user can easily unlock the locking mechanism 30 by operating the adjustment housing 31, thus separating the first connector 10 and the second connector 20, providing the advantage of convenient disassembly or installation.

[0045] The above embodiments are merely illustrative of the technology and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify and vary the above embodiments without departing from the technical principles and spirit of this utility model; therefore, the scope of protection of this utility model should be as described in the claims.
