Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a connecting device. Background Art

[0002] Existing electrode strip connectors typically consist of a metal button, a metal frame, and silicone. The metal button connects to one end of the electrode strip, and the metal frame connects to the other. To connect, the metal button is manually snapped into place inside a hole in the metal frame, completing the connection. This existing connection structure is slow and difficult to connect and release, resulting in a significant sense of blockage. Furthermore, it only provides connection functionality, lacking electrical signal transmission and rapid positioning capabilities. Its use cases are limited, and it also suffers from issues such as loose or cumbersome locking.

[0003] To address the aforementioned technical issues, a self-locking connection device has emerged on the market, comprising a female connector and a male connector. The female connector comprises a first housing, an annular groove configured to mate with the male connector, a first magnetic portion disposed at the bottom of the annular groove, an elastic limiting portion disposed on the sidewall of the annular groove, and a sliding groove formed on one side of the annular groove to form a guide groove. The male connector comprises a second housing, a columnar protrusion configured to mate with the annular groove of the first housing, and a second magnetic portion disposed on the columnar protrusion. The second magnetic portion and the elastic limiting portion form a snap-fit ​​structure, enabling the second housing of the male connector to slide out of the annular groove only along the direction of the guide structure. While this device overcomes the aforementioned issues to a certain extent, the guide groove formed by the male and female connectors facilitates connection, making it easy for the male connector to fall off the exit of the guide groove after connection, rendering the locking structure less secure.

[0004] Therefore, how to improve the connection strength of existing connection devices has become a technical problem that needs to be solved urgently. Summary of the Invention

[0005] The main purpose of the present invention is to provide a connecting device, aiming to improve the connection strength of the existing connecting devices.

[0023] Figure 1 This is a schematic diagram of the explosion structure of the first embodiment of the present invention.

[0024] Figure 2 This is a schematic diagram of the explosion structure from another perspective of the first embodiment of the present invention. DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation of the present invention.

[0026] like Figures 1 to 2 As shown, in order to achieve the above-mentioned purpose, the present invention proposes a connecting device, including: a first connecting member 10 and a second connecting member 19 that can be interlocked, and a locking assembly for locking the first connecting member 10 and the second connecting member 19 that are interlocked to limit the separation of the first connecting member 10 and the second connecting member 19.

[0027] Specifically, a connecting device includes a first connecting member 10, a second connecting member 19, and a locking assembly.

[0028] The first connector 10 is made of a plastic material. Plastic materials offer advantages such as light weight, low cost, and ease of fabrication. Depending on design requirements, the first connector 10 can also be made of a metal material, such as an aluminum alloy or alloy steel. Metal materials offer advantages such as strong support and wear resistance.

[0029] The second connecting member 19 and the locking assembly are made of the same material as the first connecting member 10 and have the same advantages, which will not be described in detail here.

[0030] After the first connecting member 10 and the second connecting member 19 are buckled together, the first connecting member 10 and the second connecting member 19 are locked by the locking assembly, thereby further improving the connection strength between the first connecting member 10 and the second connecting member 19.

[0031] By adopting the above technical solution, after the first connecting member 10 and the second connecting member 19 are buckled together, the first connecting member 10 and the second connecting member 19 that are buckled together are locked by the locking assembly, thereby improving the connection strength of the first connecting member 10 and the second connecting member 19.

[0032] In one embodiment of the present application, the plane where the working surface of the first connecting member 10 is located is defined as a horizontal plane; the locking assembly is used to limit the relative movement of the first connecting member 10 and the second connecting member 19 on the horizontal plane;

[0033] The first connecting member 10 includes a connecting portion and a fixing portion, and the connecting portion is provided with at least one first limiting through hole 22 whose extension direction is not perpendicular to the horizontal plane; the connecting portion of the second connecting member 19 is provided with a first limiting protrusion 26 that can be inserted into the first limiting through hole 22 and is used to limit the relative movement of the first connecting member 10 and the second connecting member 19 in a direction perpendicular to the horizontal plane.

[0034] Specifically, the plane where the working surface of the first connecting member 10 is located is defined as the horizontal plane, and the working surface of the first connecting member 10 is the surface of the first connecting member 10 that contacts the second connecting member 19. The locking assembly restricts the horizontal movement of the first connecting member 10 and the second connecting member 19.

[0035] A first limiting through hole 22 is provided on the connecting portion of the first connecting member 10 . The extending direction of the first limiting through hole 22 is not perpendicular to the horizontal plane, which means that the first limiting through hole 22 is inclined.

[0036] The number of the first limiting through holes 22 can be one, two, three, etc. When the number of the first limiting through holes 22 is more than two, the first limiting through holes 22 not only realize the connection between the first connecting member 10 and the second connecting member 19, but also have the effect of reducing weight.

[0037] The second connector 19 also includes a connecting portion and a fixing portion. A first stopper protrusion 26 is provided on the connecting portion. When the first connector 10 and the second connector 19 are engaged, the first stopper protrusion 26 engages within the first stopper through-hole 22. The number of first stopper protrusions 26 is equal to and corresponds to the number of first stopper through-holes 22. This improves the connection strength when the first connector 10 and the second connector 19 are engaged. Of course, depending on design requirements, the number of first stopper protrusions 26 can be less than the number of first stopper through-holes 22, thereby facilitating adjustment of the connection position between the first connector 10 and the second connector 19.

[0038] The first limiting protrusion 26 cooperates with the first limiting through hole 22 to limit the relative movement of the first connecting member 10 and the second connecting member 19 in a direction perpendicular to the horizontal plane. That is, the first limiting protrusion 26 and the first limiting through hole 22 cooperate with each other to achieve the tilted engagement of the first connecting member 10 and the second connecting member 19.

[0039] While the locking assembly restricts relative movement of the first connecting member 10 and the second connecting member 19 in the horizontal plane, the first limiting protrusion 26 and the first limiting through hole 22 restrict relative movement of the first connecting member 10 and the second connecting member 19 in a direction perpendicular to the horizontal plane, further enhancing the connection strength between the first connecting member 10 and the second connecting member 19.

[0040] By adopting the above technical solution, the connection strength between the first connecting member 10 and the second connecting member 19 is further improved through the mutual cooperation of the locking assembly, the first limiting through hole 22, and the first limiting protrusion 26. The structure is simple and easy to implement.

[0041] In one embodiment of the present application, a first magnet 24 is provided at the connecting portion of the first connecting member 10 ; a second magnet 25 is provided at the connecting portion of the second connecting member 19 that cooperates with the first magnet 24 to facilitate alignment of the first connecting member 10 and the second connecting member 19 .

[0042] Specifically, the first magnet 24 is detachably connected to the connecting portion of the first connecting member 10, for example, by snap-fitting. The detachable connection facilitates the installation and removal of the first magnet 24 and facilitates subsequent maintenance. Of course, according to design requirements, the first magnet 24 and the connecting portion of the first connecting member 10 can be connected in a fixed connection manner, such as integrally formed. The use of a fixed connection can improve the connection strength between the first magnet 24 and the connecting portion of the first connecting member 10. It is conceivable that when the first magnet 24 is provided on the first connection, the material used for the first connecting member 10 needs to not interact with the first magnet 24.

[0043] The second magnet 25 is detachably connected to the connecting portion of the second connecting member 19, for example, by snap-fitting. The detachable connection facilitates the installation and removal of the second magnet 25 and facilitates subsequent maintenance. Of course, depending on the design requirements, the second magnet 25 and the connecting portion of the second connecting member 19 can be connected in a fixed manner, such as by integral molding. The use of a fixed connection can improve the connection strength between the second magnet 25 and the connecting portion of the second connecting member 19. It is conceivable that when the second magnet 25 is provided on the second connection, the material used for the second connecting member 19 needs to not interact with the first magnet 24.

[0044] When the first connecting member 10 is fastened to the second connecting member 19 , the first magnet 24 and the second magnet 25 attract each other, thereby facilitating the alignment of the first connecting member 10 and the second connecting member 19 .

[0045] The above technical solution has a simple structure and is easy to implement.

[0046] In one embodiment of the present application, the locking assembly includes: a fixing plate 13 , on which at least one second limiting protrusion 14 and at least one third limiting protrusion 18 are provided;

[0048] When the first connecting member 10 and the second connecting member 19 are buckled with each other, the second limiting protrusions 14 are inserted into the second limiting grooves 11 in a one-to-one correspondence, and the third limiting protrusions 18 are inserted into the third limiting grooves 20 in a one-to-one correspondence.

[0049] Specifically, the locking assembly includes a fixing plate 13 , at least one second limiting protrusion 14 provided on the fixing plate 13 , and at least one third limiting protrusion 18 .

[0050] The fixing plate 13 is made of plastic material, which has the advantages of being light, low cost, and easy to manufacture. The second limiting protrusion 14 and the third limiting protrusion 18 are both integrally formed with the fixing plate 13 .

[0051] The number of the second limiting protrusions 14 can be one, two, three, etc.

[0052] When the number of the second limiting protrusion 14 is one, the second limiting protrusion 14 is provided on the first end of the fixing plate 13 .

[0053] When there are two second limiting protrusions 14, the two second limiting protrusions 14 are arranged side by side on the first end of the fixing plate 13, with a gap left between the two second limiting protrusions 14. Preferably, there are two second limiting protrusions 14.

[0054] The number of the third limiting protrusions 18 can be one, two, three, etc.

[0055] When the number of the third limiting protrusion 18 is one, the third limiting protrusion 18 is provided on the second end of the fixing plate 13 .

[0056] When there are two third limiting protrusions 18, the two third limiting protrusions 18 are arranged side by side on the second end of the fixing plate 13, with a gap left between the two third limiting protrusions 18. Preferably, there are two third limiting protrusions 18.

[0057] The fixing portion of the first connecting member 10 is provided with second limiting grooves 11 , which are equal in number to the second limiting protrusions 14 and correspond one to one.

[0058] The fixing portion of the second connecting member 19 is provided with third limiting grooves 20 , which are equal in number to the third limiting protrusions 18 and correspond one to one.

[0059] When the first connecting member 10 and the second connecting member 19 are buckled together, the second limiting protrusions 14 are inserted into the second limiting grooves 11 in a one-to-one correspondence, and the third limiting protrusions 18 are inserted into the third limiting grooves 20 in a one-to-one correspondence.

[0060] The above technical solution has a simple structure and is easy to implement.

[0061] In one embodiment of the present application, a third magnet 23 is provided in the second limiting groove 11, and a fourth magnet 28 cooperating with the third magnet 23 is provided on the second limiting protrusion 14; and / or

[0062] A fifth magnet 27 is disposed in the third limiting groove 20 , and a sixth magnet 30 that cooperates with the fifth magnet 27 is disposed on the third limiting protrusion 18 .

[0063] Specifically, a third magnet 23 is provided in the second limiting groove 11 , and a fourth magnet 28 that attracts the third magnet 23 is correspondingly provided on the second limiting protrusion 14 .

[0064] A fifth magnet 27 is provided in the third limiting groove 20 , and a sixth magnet 30 is correspondingly provided on the third limiting protrusion 18 to attract the fifth magnet 27 .

[0065] By adopting the above technical solution, the locking assembly can be quickly connected to the first connecting member 10 and the second connecting member 19 through the mutual attraction of the magnets. The structure is simple and easy to implement.

[0066] In one embodiment of the present application, the second limiting protrusion 14 is larger or smaller than the third limiting protrusion 18 .

[0067] Specifically, the second limiting protrusion 14 is larger or smaller than the third limiting protrusion 18, that is, the size of the second limiting protrusion 14 is not equal to the size of the third limiting protrusion 18, thereby achieving the anti-fouling function of the locking assembly. In this application, the unequal size refers to at least one of the length, width, and height being unequal.

[0068] By adopting the above technical solution, the second limiting protrusion 14 is made larger or smaller than the third limiting protrusion 18 to realize the foolproof function of the locking assembly, which has a simple structure and is easy to implement.

[0069] In one embodiment of the present application, a snap assembly is further included for limiting the separation between the locking assembly and the first and second connecting members 10 and 19 when the locking assembly locks the first and second connecting members 10 and 19 .

[0070] Specifically, the buckle assembly is used to clamp the locking assembly to the first connecting member 10 and the second connecting member 19, thereby preventing the locking assembly from falling off between the first connecting member 10 and the second connecting member 19. This improves the stability of the locking assembly during operation.

[0071] In one embodiment of the present application, the buckle assembly includes: a first telescopic member 29 connected to the locking assembly and capable of being buckled with the first connecting member 10 to limit the movement of the locking assembly in a direction perpendicular to the horizontal plane; and

[0072] A second telescopic member 31 is connected to the locking assembly and can be engaged with the second connecting member 19 to limit the movement of the locking assembly in a direction perpendicular to the horizontal plane.

[0073] Specifically, the buckle assembly includes a first telescopic member 29 and a second telescopic member 31 .

[0074] The first telescopic member 29 is connected to the locking assembly, and the second telescopic member 31 is connected to the locking assembly.

[0075] The first telescopic member 29 can be buckled on the first connecting member 10 to limit the locking assembly from moving in a direction perpendicular to the horizontal plane.

The number of pins can be adjusted based on specific needs.
