Description

Technical Field

[0001] The utility model relates to the technical field of electronic device connection, in particular to a snap - lock type connection mechanism. Background Technique

[0002] As is well known, in larger electronic devices, the internal circuit boards and various electronic components are very complex. In the structural design, not only the spatial position of the layout needs to be reasonably designed, but also the connection between the circuit board and the electronic components, or between the electronic components needs to be considered. And the connection between these components relies on the connection mechanism. Therefore, the quality of the connection mechanism directly affects the circuit stability of the electronic device.

[0003] Currently, the existing connection mechanisms are generally divided into two types. One is to use plug - in connectors. Corresponding connecting wires with male connectors and female sockets are respectively arranged on two circuit components. During connection, direct plug - in connection is carried out. Although this connection mechanism can complete assembly quickly, after assembly, it is easy to become loose. When it comes to horizontal connection between surfaces, a space for accommodating the connecting wires needs to be designed, which will increase the thickness of the electronic device and is not conducive to the connection requirements of ultra - thin devices. The other type directly uses male and female connectors for plug - in. Although this does not increase the thickness of the device, the connection is a rigid connection. After the device is connected, it is easy to have problems such as inability to adjust during assembly or when other components are assembled. Either it cannot adapt to the tolerance value after the assembly of each component, or it can only be forced to push, resulting in damage to the connection mechanism. Content of the Utility Model

[0025] like Figures 1 to 6 As shown, a latching connection mechanism provided in this embodiment includes a first electronic component 1, a second electronic component 2, a first latching seat 3, a second latching seat 4 and a latching sheet 5, the surface of the first electronic component 1 is provided with a first circuit pad 11, the surface of the second electronic component 2 is provided with a second circuit pad 21, the first latching seat 3 is embedded with a first terminal 31, at least one of the first terminals 31 is welded to the first circuit pad 11, so that the first latching seat 3 is fixed to the first electronic component 1, and the first terminal 31 is provided with at least one outwardly warped and exposed The first locking seat 3 has a contact spring 32, symmetrical locking protrusions 33 are respectively provided on both sides of the first locking seat 3, the second locking seat 4 is embedded with a second terminal 41, one end of the second terminal 41 is welded to the second circuit pad 21, so that the second locking seat 4 is fixed to the second electronic component 2, the other end of the second terminal 41 is a contact surface 42 and is placed on the outer surface of the second locking seat 4, and the side of the second locking seat 4 is provided with a limited position opening 43, and both ends of the locking piece 5 are provided with a return hook portion 51, so that the locking piece 5 is in a "J" shape, and a locking opening 52 is provided on the return hook portion 51;

[0026] Wherein, the width of the limiting opening 43 is greater than the width of the locking projection 33. The second locking seat 4 is placed on the first locking seat 3. The locking projection 33 is placed in the limiting opening 43, and there is a movable gap 100 between the locking projection 33 and the side wall of the limiting opening 43. The locking piece 5 is placed on the second locking seat 4 in alignment, and the hook portions 51 at both ends of the locking piece 5 are buckled at the locking projection 33 after deformation, so that the locking projection 33 is inserted into the locking opening 52, and the contact surface 42 between the contact elastic piece 32 and the second terminal 41 forms contact.

[0027] It should be noted that the electronic component in this embodiment can be various circuit devices, such as an LED light strip and a flexible PCB board. The most commonly used is the application on an LED light strip, and it is applied to the assembly of an embedded LED light strip, such as a display screen.

[0028] For this embodiment, the main innovative principle is that the first locking seat 3, the second locking seat 4, and the locking piece 5 constitute a locking connection between the first electronic component 1 and the second electronic component 2, so that there are no redundant wires in the connection, meeting the connection thickness requirements of thin devices; most importantly, there is a movable gap 100 between the locking projection 33 and the side wall of the limiting opening 43. When the second locking seat 4 is assembled, relying on this movable part gap, it can move back and forth in the horizontal direction to make up for the design requirements of the electronic component to ensure the smooth realization of the functions of the electronic component. Specifically, for example, when an LED light strip is assembled with another LED light strip in a device, if there is a tolerance (generally, any component will have a tolerance more or less, especially when there is thermal expansion and contraction between materials, there will be a tolerance value, but it will not vary too much), so relying on the movable gap 100 between the limiting opening 43 and the locking projection 33, it can be directly adapted, so that the second locking seat 4 can be pushed along the X-axis direction to neutralize the generated tolerance value.

[0029] Furthermore, to improve the firmness of the locking, the side of the second locking seat 4 in this embodiment extends beyond the first locking seat 3. The locking piece 5 is torn inwardly at the side of the hook portion to form a bent portion 53. The first locking seat 3 is provided with an avoidance position at the bent portion 53. The top of the bent portion 53 presses against the part of the second locking seat 4 that extends beyond the first locking seat 3. In this way, the locking piece 5 not only forms a fastening structure between the first locking seat 3 and the second locking seat 4, but also relies on this bent portion 53 to press against and restrict the locking piece 5 from being pulled out in the vertical direction, so as to achieve the effect of anti-locking and improve the firmness of the locking.

[0030] Furthermore, when disassembling for maintenance, in order to facilitate the bending portion 53 to be manually disengaged from the top contact, the top end of the bending portion 53 of the present embodiment and the part facing the outside are provided with a slope surface, so that when the external force pries the return hook portion 51 of the locking plate 5 toward both sides, the bending portion 53 can be avoided from being limited, thereby achieving the effect of facilitating disengagement.

[0031] Furthermore, in order to facilitate personnel to escape from the clamping effect of the locking plate 5, the end of the return hook portion 51 of the present embodiment is bent upward to form a prying edge 54. The establishment of the prying edge 54 can facilitate the application of force here, and then force the return hook portion 51 to expand outward, so that the locking protrusion 33 can be smoothly separated from the locking mouth 52, thereby removing the locking plate 5.

[0032] Furthermore, in order to facilitate maintenance, that is, to disengage the locking piece 5, the hook portion 51 of the present embodiment is provided with an insertion notch 55 at the lower end of the locking opening 52, and the locking protrusion 33 is provided with an escape opening 36 relative to the notch 55. With this design, it is convenient for an external disassembly jig to be mechanically dismantled. For example, when the jig is being repaired, the movable rod of the jig is directly inserted into the insertion notch 55, and then it is bent outward to open the locking piece 5, so that the locking piece 5 can be disengaged and removed.

[0033] Furthermore, the fixed connection between the first electronic component 1 and the first locking seat 3 of the present embodiment is maintained by welding, and in order to avoid direct damage to the welding of the first circuit pad 11 once bending occurs, the present embodiment is specially welded with first fixing plates 12 on both sides of the first electronic component 1 located at the first circuit pad 11, and the first locking seat 3 is provided with a first insertion hole 34 relative to the first fixing plate 12. When the first electronic component 1 and the first locking seat 3 are assembled, the first fixing plate 12 is inserted into the first insertion hole 34 and forms a lock. In this way, when pulling occurs on the outside, it is first limited by the connection between the first fixing plate 12 and the first locking seat 3. Only when the welding of the first fixing plate 12 fails, will it affect the welding of the first circuit pad 11, thereby playing a role of insurance.

[0034] Among them, for the locking structure between the first fixing plate 12 and the first locking seat 3, specifically, a barb portion 13 is provided at the top of the first fixing plate 12, and a slot 35 is provided in the first insertion hole 34. After the first fixing plate 12 is inserted into the first insertion hole 34, the barb portion 13 slides into the slot 35 to form a locking effect on the first fixing plate 12.

[0035] Furthermore, the fixed connection between the second electronic component 2 and the second locking seat 4 of the present embodiment is maintained by welding, and in order to avoid direct damage to the welding of the second circuit pad 21 in the event of bending, the second electronic component 2 is welded with a second fixing piece 22 on both sides of the second circuit pad 21, and the other end of the second fixing piece 22 is fixedly connected to the second locking seat 4, and the fixed connection form can be injection molding, or plug-in connection. In this way, when pulling occurs on the outside, the connection between the second fixing piece 22 and the second locking seat 4 is first used for limiting, and only when the welding of the second fixing piece 22 fails, will it affect the welding of the second circuit pad 21, thereby playing a role of insurance.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
