[0006] Preferably, the bottom surface of the female head 2 is aligned with the male head 1, and the remaining three edges are provided with a convex edge 22, which is used for abutting against the male head 1 to form a certain height difference when the male head 1 is reversely inserted.

[0007] Preferably, the male head 1 is provided with anti-slip baffles 12 on both sides, and the female head 2 is provided with force recesses 23 on both sides.

[0008] Preferably, the diameters of the taper guide section 111, the main body contact section 112 and the limiting flange 113 are gradually increased, so that the copper column forms a stepped structure; the local section of the head of the copper column is the taper guide section 111, the local section of the tail of the copper column is the limiting flange 113, and the main body section of the middle of the copper column is the main body contact section 112.

[0009] Preferably, the ground copper column 11G is arranged to be offset to one side, and the jack 21 is also offset to the same side synchronously, so that the three copper columns of the male head 1 and the three jacks 21 of the female head 2 form an asymmetric position layout.

[0010] Preferably, the diameter of the main body contact section 112 of the ground copper column 11G is greater than that of the phase copper column 11L, and the surface of the ground copper column 11G is provided with a gold plating layer.

[0011] Preferably, the main body contact section 112 of the ground copper column 11G is provided with a fuse neck 114, and the cross-sectional area of the fuse neck 114 is smaller than that of other parts of the main body contact section 112.

[0012] Preferably, the distance between the anti-skid baffle 12 and the edge of the male head 1 is 1 / 3 of the total length of the male head 1, and the distance between the force applying groove 23 and the edge of the female head 2 is 2 / 3 of the total length of the female head 2.

[0013] Preferably, the periphery of the jack 21 of the female head 2 is provided with an annular fluorescent identification ring 24.

[0014] Preferably, the adjacent connection ends of the male head 1 are provided with an insulating baffle 13, and the height of the baffle exceeds the end surface of the copper column 11.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] 1. The ground copper column adopts a lengthened guide section and an offset design, which ensures that the ground line is connected first in the plugging process, strictly follows the safety specification of the national standard GB / T 11918 "connecting the ground first and then connecting the power", effectively reduces the risk of electric leakage, and provides more reliable power supply protection for users. At the same time, the fuse neck at the root of the ground copper column is designed, when the current exceeds the rated threshold, the high heat generated by the small cross-sectional area promotes the rapid melting of the fuse neck, timely cuts off the circuit, and compared with the traditional unprotected design, can effectively reduce the fire risk caused by overload.

[0017] 2、Anti-misplug safety design: through the double physical interference structure of the convex edge and the offset of the ground copper column, a comprehensive foolproof protection system is built. The height difference formed by the convex edge produces mechanical resistance when inserted in reverse, and the offset design of the ground copper column and its corresponding female socket ensures that the connector can only be connected in the correct direction from the structural level. This double protection mechanism greatly reduces the probability of misplug, compared with the traditional single anti-misplug structure, it can effectively reduce the circuit failure rate caused by misplug, and effectively ensure the safety of electricity.

[0018] 3、Night operation convenience improvement: the annular fluorescent identification ring on the periphery of the female socket uses long-acting energy storage light-emitting materials and can emit light continuously in dark environments. This design effectively solves the problem of traditional connectors being difficult to quickly locate in low light environments, significantly improves installation positioning efficiency, reduces construction errors, and improves lamp installation efficiency in night or low light environments, greatly improving construction convenience.

[0019] 4、Ergonomic optimization: the lever design of the male head anti-slip baffle and the female head force groove is based on the principle of human engineering, which reasonably disperses the force during insertion and removal, effectively reducing the insertion and removal force. Compared with traditional structures, actual tests show that the required force for operation is reduced. Not only does it reduce the labor intensity of the operator, but it also reduces the damage to the connector caused by excessive force, significantly improving the comfort and convenience of operation, especially suitable for long-term and high-frequency installation scenarios.

[0022] Fig. 3 is the cross-sectional structure schematic view of the male head inserted into the female head of the utility model; DETAILED DESCRIPTION

[0023] The utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0024] For example, Figs. 1-3As shown, a lamp fixture quick connector includes a male head 1 and a female head 2. The male head 1 is provided with three copper columns arranged in a straight line, which are a middle ground copper column 11G and two side phase copper columns 11L. Each copper column 11 includes a tapered guide section 111, a main body contact section 112 and a limiting flange 113 from front to back in order, and the diameters of the tapered guide section 111, the main body contact section 112 and the limiting flange 113 increase in turn, for example, the diameters of the copper column tapered guide section 111, the main body contact section 112 and the limiting flange 113 are 2.5mm, 3.0mm and 3.5mm in turn, with a tolerance of ±0.05mm. The local section of the head of the copper column is the tapered guide section 111, the local section of the tail of the copper column 1 is the limiting flange 113, and the main body section of the middle of the copper column 11 is the main body contact section 112. The length of the tapered guide section 111 of the middle ground copper column 11G is greater than that of the two side phase copper columns 11L, so that the ground copper column 11G can enter the female head 2 first when inserted, playing a guiding role while the ground is connected in advance, meeting the grounding requirements of the national standard GB / T 11918 "first grounding and then power on".

[0025] The female head 2 is provided with a socket 21 matched with the copper column, the bottom surface of which is aligned with the male head 1, and the remaining three edge surfaces are provided with a convex edge 22. This convex edge structure not only realizes the anti-misplug function, but also innovatively serves as a tactile guide: when the operator performs blind insertion, the finger can perceive the tactile difference between the convex edge 22 and the smooth side surface of the male head 1 by touching the edge profile of the female head 2, and quickly judge the correct insertion direction. The convex edge 22 adopts a stepped transition design, and the edge forms a height difference of 0.8-1.2mm with the surface of the male head 1, which produces obvious tactile feedback when the hand is held, so that the operator can accurately position without visual inspection, significantly improving the insertion efficiency and accuracy in dark environments or small spaces.

[0026] The male head 1 is provided with anti-slip baffles 12 on both sides, and the distance between the anti-slip baffles 12 and the edge of the male head 1 is 1 / 3 of the total length of the male head. When the operator inserts or pulls out, the hand or tool contacts the anti-slip baffles 12, increasing the friction force and preventing slipping. The female head 2 is provided with force grooves 23 on both sides, and the distance between the force grooves 23 and the edge of the female head 2 is 2 / 3 of the total length of the female head. This facilitates the operator to apply insertion and pulling force, making the operation more labor-saving.

[0027] The ground copper column 11G is arranged offset to one side, and the mounting position thereof on the male head 1 is offset from the center axis by 0.8-1.5 mm, and the specific offset amount is set according to the safety standard, and the ground insertion hole in the female head 2 insertion hole 21 is offset to the same side by the same distance, so that the insertion hole layout is completely matched with the copper column position. The offset structure forms a "positioning key" effect: when the male head 1 is inserted with the female head 2, only the ground copper column 11G and the corresponding offset insertion hole can be guided to complete correct connection, if inserted reversely or in wrong position, the offset position of the copper column and the insertion hole will form mechanical interference, and the insertion cannot be completed, so that the short circuit risk or equipment damage caused by wiring error is avoided. The main contact section 112 of the ground copper column 11G is larger in diameter than the phase copper column 11L, and is provided with a gold plating layer on the surface, so that the conductivity and the anti-oxidation capability are improved. The main contact section 112 of the ground copper column 11G is provided with a fuse neck 114, and the cross-sectional area of the fuse neck 114 is smaller than that of the main contact section 112, so that when the circuit is abnormal, the fuse neck 114 is fused first, and the circuit safety is protected.

[0028] The insertion hole 21 of the female head 2 is provided with an annular fluorescent identification ring 24, and the fluorescent identification ring 24 emits fluorescence in a relatively dark environment, so that the operator can quickly find the insertion hole position, and the operation efficiency is improved. The adjacent wiring ends of the male head 1 are provided with an insulating barrier 13, and the height of the barrier is higher than the end surface of the copper column 11, so that the wires of the wiring ends are prevented from contacting other components, and the short circuit risk is avoided.

[0029] In summary, the lamp quick connector of the utility model realizes quick, safe and convenient connection through the cooperative design of various components, and has good practicability and popularization value.

[0030] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
