Description

Lamp strip connector and corresponding lamp strip assembly
Technical Field
Embodiments of the present disclosure relate to the field of lighting, and more particularly, to a strip connector and a strip assembly including the same.
Background
At present, the high-voltage lamp strip is small in overall current, long in manufacturable length and capable of meeting the requirement of long-distance decorative lighting without a complex series connection process, so that the high-voltage lamp strip is widely applied to household troffer lighting and other decorative lighting.
However, the connection mode of the high-voltage lamp strip and the rectification end output in the market is to directly insert a contact pin into a wire hole of the lamp strip and a female copper terminal of the rectification output end, and the electric connection mode of the contact pin does not meet the requirement of a binding post in the lamp standard. In fact, the connection mode that the contact pin is directly inserted into the wire hole of the lamp strip is disadvantageous because the soft rubber of the lamp strip can become soft due to the action of heat in the use process, so that the electric connection of the contact pin can become loose, contact failure can be caused, and then poor electrification of the lamp strip is caused. In addition, poor contact can also easily lead to undesirable heating and create a fire hazard. In addition, in the operation mode of directly inserting the contact pin into the lamp strip wire guide hole, the contact pin is easy to be inserted in a biased manner when being inserted into the lamp strip wire guide hole, so that the contact area between the contact pin and the wire becomes uneven, the contact pin may need to be pulled out and then repeatedly inserted, and the operation is difficult to be satisfactory.
For example, CN103672779A proposes a light strip connection assembly. The lamp strip connecting component comprises a male plug and a female plug which can be butted with each other, wherein the male plug is provided with a bulge, the female plug is provided with a hole corresponding to the bulge, and the lamp strip connecting component still adopts an electric connection mode that a contact pin is connected with a wire hole of a flexible LED lamp strip in an inserting mode.

Fig. 1 shows a schematic connection structure of a lamp strip assembly 100 comprising a lamp strip connector and a lamp strip according to a first embodiment of the present disclosure.
As shown in fig. 1, the light strip assembly 100 may comprise a light strip 50 and a light strip connector 10 that may adapt the light strip 50 to a power supply input, wherein the light strip 50 is adapted to emit illumination light of a desired color.
In some embodiments, the light strip 50 may be flexible and have a predetermined length to meet the predetermined length of decorative lighting requirements of the application. However, in other embodiments, a flexible light strip 50 is not required.
The function of the strip connector 10 is to connect the strip 50 to a power supply input. In some embodiments, the power input may be, for example, a rectified output (not labeled) such as the rectifier 12, so that the light strip 50 may be connected to a power source such as alternating current. However, this is not a limitation, and in other embodiments, the power supply input may be a dc power supply that does not include a rectified output.
In embodiments comprising a rectifier 12, the input of the rectifier 12 may for example be connected to an electrical plug 11 adapted to be plugged directly into an electrical supply socket, such as a mains supply, to receive a supply current, such as alternating current. The structure and function of the rectifier 12 and the electrical plug 11 are well known and will not be described in detail here.
The strip connector 10 of the first embodiment of the present disclosure may mainly include a male plug assembly 30, a female plug assembly 20, and a pin assembly 40 interposed between the male plug assembly 30 and the female plug assembly 20.
The detailed structures of the male plug assembly 30, the female plug assembly 20, and the pin assembly 40 in the strip connector 10 according to the first embodiment of the present disclosure and the connection manner of the male plug assembly, the female plug assembly 20, and the pin assembly 40 to the strip 50 will be further described below with reference to fig. 2 to 9.
As can be seen in connection with fig. 1 and 2, the female plug assembly 20 may generally include an outer sleeve 22 and an inner core 21, e.g., overmolded within the outer sleeve 22, which may further include, e.g., an inner sleeve (not labeled) and an electrical receptacle terminal 27 overmolded at least partially therein, wherein one end of the electrical receptacle terminal 27 may be electrically connected to a power input such as an output (not labeled) of the rectifier 12 and the other end may be electrically plugged with a pin 41, which will be described later. By way of example only, the electrical receptacle terminals 27 may be, for example, hollow round copper terminals.
In some embodiments, the wires leading from the power supply input (such as the output of the rectifier 12) may include at least two conductive cores, the inner sleeve (not labeled) functioning to: the stripped at least two conductive cores are separated and the electrical receptacle terminal 27 is secured.
One end 23 of the outer sleeve 22 may for example be connected to a power supply input such as a rectified output of the rectifier 12, and the other end 24 may be provided with a first cavity 25 allowing at least a portion of the male plug assembly 30 to be inserted therein.
The pin assembly 40 may be disposed between the male assembly 30 and the female assembly 20 and functions as an electrical plug between the male assembly 30 and the female assembly 20. As shown in fig. 3, the pin assembly 40 may include a pin 41 and a fixing block 45 for supporting and fixing the pin 41.
The pin 41 may include a first end 46 and an opposite second end 47, wherein the first end 46 may be securely electrically plugged into an electrical receptacle terminal 27 (e.g., a hollow round copper terminal) on the core 21, and the second end 47 may be exposed within the first cavity 25, such that the second ends 47 of the pin 41 and the male assembly 30 are electrically plugged into each other when the male assembly 30 is subsequently plugged into the female assembly 20, thereby electrically connecting the male assembly 30 to the female assembly 20.
Although in the above description, the pin assembly 40 exists independently of the male and female assemblies 30 and 20. However, this is not a limitation and pin assembly 40 may also be present as part of male assembly 30 or female assembly 20 in other embodiments without departing from the spirit of the present invention.
The male plug assembly 30 may include a circuit module 31. For this purpose, fig. 5 further shows an exploded schematic diagram of the circuit module 31. As shown in fig. 5, the circuit module 31 may include a circuit board 32, pin contacts 34, and line contacts 33, wherein the pin contacts 34 and the line contacts 33 may be both mounted on a first surface 321 of the circuit board 32 and electrically connected to each other. The wire contact 33 functions to secure and electrically connect the wire terminals 51 of the light strip 50 (see fig. 1), while the pin contact 34 functions to securely electrically mate with the pin 41 of the pin assembly 40. For example only, the pin contacts 34 may be formed from a clipped metal dome.
In order to achieve the fixing of the pin contacts 34 and the line contacts 33 on the circuit board 32, the pin contacts 34 can be fastened, for example, on mounting holes 324 of the circuit board 32, and the line contacts 33 can be fastened, for example, on mounting holes 325 of the circuit board 32.
In some embodiments, as shown in fig. 6, the pin contacts 34 may be electrically connected to the line contacts 33 via conductive traces 323 on the second surface 322 of the circuit board 32, thereby achieving an electrical connection between the pin contacts 34 and the line contacts 33. However, this is not a limitation, and it will be appreciated that in other embodiments, the conductive traces 323 may be disposed on the first surface 321 of the circuit board 32. It will be appreciated that the conductive traces 323 may save the use of electrical wiring; in still other embodiments, the pin contacts 34 may be electrically connected to the line contacts 33 in a manner such as electrical wiring.
As previously described, the wire contact 33 functions to secure and electrically connect the wire terminals 51 of the light strip 50, fig. 7 further illustrating an exploded view of the wire contact 33; fig. 8 shows a schematic cross-sectional view of the electrical connection of the wire contact 33 to the wire terminal 51 of the light strip 50.
As can be seen in fig. 7 and 8, the wire contact 33 may include a post 333, a contact spring 332, and a screw 331.
The post 333 may include a first post hole 335 and a second post hole 337 communicating with each other, wherein the first post hole 335 functions to allow insertion of a portion of the contact spring 332, and the second post hole 337 functions to allow insertion of the screw 331. In some embodiments, the first post hole 335 and the second post hole 337 may be perpendicular to each other such that the screw 331, when tightened into the second post hole 335, may substantially vertically abut the contact spring 332 within the first post hole 335.
In some embodiments, the contact spring 332 may be a U-shaped spring, which may include a first arm 336 and a second arm 338 that are generally U-shaped relative to each other, wherein the second arm 338 is provided with an aperture 334 adapted to align with the second post 337. In a state where the first arm 336 of the contact spring 332 is inserted into the first post hole 335, the opening 334 of the second wall 338 may be aligned with the second post hole 337 of the post 333, which may facilitate both the opening 334 of the screw 331 and the second post hole 337.
When mounted, one end of the screw 331 may sequentially pass through the opening 334 of the U-shaped dome, the second post hole 337 of the post 333, and reach the first post hole 335, and may press the connection terminal 51 of the light strip 50 via the first arm 336, thereby achieving a firm electrical connection between the wire contact 33 and the connection terminal 51 of the light strip 50. The electrical connection between the wire contact 33 and the connection terminal 51 of the light strip 50 avoids a direct electrical plug of a pin with a wire guide of the light strip.
Referring back to fig. 1 and 2, to facilitate electrical mating of the male plug assembly 30 to the female plug assembly 20, in some embodiments, the male plug assembly 30 may further include a guide block 35 that functions to secure the circuit board of the circuit module 31 and guide the electrical mating of the male plug assembly 30 into the first cavity 35 of the female plug assembly 20.
Fig. 4 further illustrates a detailed structural schematic of the guide block 35 which may be adapted to mount the circuit board 32.
As can be seen in connection with fig. 2 and 4, the guide block 35 may comprise a first end 39 and a second end 38, wherein the first end 39 is provided with a second cavity 351 (see fig. 8) allowing an end (not labeled) of the light strip 50 to be inserted therein, and the second end 38 is provided with a slot 37 for mounting the circuit board 32. Further, the guide block 35 is also provided with a through hole 36 communicating the first end 39 and the second end 38. The through hole 36 is provided so that the wire connection terminal 51 of the light strip 50 conveniently passes in from the first end 39 of the guide block 35 and out from the second end 38 of the guide block 35 for making electrical connection with the wire contact 33 as described above. It will be appreciated that the design of the guide block 35 may securely protect the end (not labeled) of the light strip 50, the wire terminals 51 and the wire contacts 33, which may effectively improve the reliability of the electrical connection of the light strip 50 to the wire contacts 31 and avoid the electrical connection being adversely affected by potential bending of the flexible light strip 50.
To facilitate insertion of the circuit board 32 mounted on the guide block 35 into the first cavity 35 of the female assembly 20, as shown in fig. 2, in some embodiments, the inner side wall of the first cavity 25 of the female assembly 20 may also be provided with a slot 251 corresponding to a side edge of the circuit board 32.
Having described the detailed structure of the strip connector 10 according to the first embodiment of the present disclosure in detail above, the electrical connection process between the male plug assembly 30, the female plug assembly 20 and the strip 50 in the strip connector 10 is briefly described as follows:
first, the connection terminals 51 of the light strip 50 may be exposed, and the connection terminals 51 may be passed through the through-holes 36 of the guide block 35. At this time, an end (not labeled) of the light strip 50 may protrude into the second cavity 351 of the guide block 35 (see fig. 8 and 9);
next, the circuit board 32 of the circuit module 31 is inserted into the insertion slot 37 of the guide block 35, and the connection terminals 51 are fastened to the wire contacts 33 of the circuit module 31, thereby achieving a secure electrical connection of the connection terminals 51 of the light strip 50 to the wire contacts 33 on the circuit board 32 (see fig. 8). At this time, the circuit module 31 together with the guide block 35 may constitute the male plug assembly 30.
Finally, the male plug assembly 30 is inserted into the female plug assembly 20 (see fig. 2, 8 and 12). In the plugged state, electrical connection of both the male and female plug assemblies 30, 20 can be achieved via the male pins 41 secured within the first cavity 25 of the female plug assembly 20, while the male plug assembly 30 can be inserted and concealed integrally into the first cavity 25 of the female plug assembly 20 (see fig. 12), which further improves the security of the electrical plug connection between the male and female plug assemblies 30, 20.
Although the male plug assembly 30 including the guide block 35 is described above with emphasis, it will be understood that the guide block 35 is provided only for plugging the circuit board 32 of the auxiliary circuit module 31 into the female plug assembly 20, and the guide block 35 is not necessarily provided. In other embodiments, the use of the guide block 35 may also be omitted.
The above description of the lamp string connector of the first embodiment of the present disclosure is made. It will be understood that the strip connector according to the first embodiment of the present disclosure can effectively avoid direct electrical insertion of a contact pin into a wire hole of a strip, and meet the requirements of a terminal in a lamp standard, and at the same time, the strip connector according to the first embodiment of the present disclosure is reliable in electrical connection with the strip and the rectification output end, and high in safety.
