Description

Technical Field

[0001] The utility model relates to the technical field of lamp holders, in particular to a wireless connection lamp holder. Background Art

[0002] However, as people's living standards gradually improve, people's requirements for lamps are not limited to lighting, so some lamp holders with other control functions are needed to control bulbs. At present, lamp holders with multiple functions need to be connected to longer wires, which makes it inconvenient to disassemble and replace the lamp holders during installation and maintenance.

[0003] Publication No. CN216929122U discloses a split lamp holder, comprising a fixed seat and a movable seat; a first contact is arranged in the middle of the fixed seat, and a wiring head is arranged on the back of the first contact; a slide groove and a mounting hole are arranged around the first contact; the width of the slide groove gradually decreases from the starting point to the end point; the movable seat comprises a lamp connecting part and a clamping part; the lamp connecting part is arranged on the front of the movable seat, and a second contact is arranged on the back of the lamp connecting part, and an LED bulb is installed on the front of the lamp connecting part; the clamping part is arranged on the back of the movable seat, and the clamping part corresponds to the slide groove; the clamping part enters the slide groove from the place where the slide groove has a large diameter and reaches the end point of the slide groove, connects the movable seat with the fixed seat, and docks the first contact with the second contact. This lamp holder first sets the fixed seat on the wall, and then clamps the movable seat for installing the bulb in the slide groove of the fixed seat through the clamping part, and realizes the power supply of the bulb when the movable seat is set on the fixed seat, but there are defects. Defect 1: When the movable seat is set on the fixed seat, it is necessary to match the position, that is, match the position of the clamping part and the slide groove, and the slide groove is composed of two arc grooves with different diameters, that is, when the clamping part enters, it is necessary to first enter the arc groove with a large diameter, and then enter the arc groove with a small diameter from the arc groove with a large diameter, and when entering, the position of the clamping part needs to be adjusted to avoid being interfered when entering the arc groove with a small diameter, so that the position of the movable seat needs to be deliberately adjusted; Defect 2: After the clamping part enters the arc groove with a small diameter, friction is formed by friction to prevent the movable seat from detaching. The stability of this method is relatively poor, that is, the friction needs to bear the weight brought by the bulb, and needs to be kept in a relatively static space. If the wall vibrates (caused by decoration, etc.), it is easy to cause the friction to fail to support the anti-detachment effect, thereby causing the movable seat to detach from the fixed seat, and it will also cause the clamping part to wear over time, thereby affecting the clamping effect.

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Referring to the accompanying drawings: This wirelessly connected lamp holder includes a lamp holder 1, and a top cover 2 that is rotatably covered on the lamp holder 1, an upper wiring assembly 3 for wiring is arranged in the top cover 2, and a lower switch assembly 4 with a preset shape and retractable when pressed is arranged in the lamp holder 1, and the lower switch assembly 4 contacts with the upper wiring assembly 3 when the top cover 2 reaches its final covering position on the lamp holder 1, and the contact can generate a pressing force to press the lower switch assembly 4 to retract and realize power-on. The principle of the utility model is that the lamp holder 1 and the top cover 2 are rotatably connected by threaded cooperation, and the opening of the lower switch assembly 4 is achieved by pressing, so that the connection method of the lamp holder 1 and the top cover 2 can meet the pressing requirement of the lower switch assembly 4, that is, the top cover 2 is rotated downward to press the lower switch assembly 4 or the top cover 2 is rotated upward to release the pressing of the lower switch assembly 4, and the operation is convenient, and can meet the quick opening and closing of the bulb. At the same time, the threaded connection has self-locking properties, that is, the lower top cover 2 will not move without the influence of external force, thereby achieving the upper wiring assembly 3 and the lower switch assembly 4 to maintain a contact state or a non-contact state, ensuring the continuous lighting or non-lighting state of the bulb.

[0022] The upper wiring assembly 3 includes a mounting seat 31, two conductive sheets 32 for contacting the lower switch assembly 4, and three terminal posts 33 for wiring and cooperating with the conductive sheets 32. The mounting seat 31 is arranged in the top cover 2 and has a countersunk structure forming a first recess 31-a and a second recess 31-b at the upper end. The first recess 31-a is used to set one of the terminal posts 33, and the second recess 31-b is used to set the other two terminal posts 33. The lower end of the mounting seat 31 has a step structure of a first protrusion 31-c, a second protrusion 31-d, and a third protrusion 31-e formed by the recess of the second recess 31-b. The first protrusion 31-c and the third protrusion 31-e both have a conductive sheet mounting cavity 31-f for setting the corresponding conductive sheet 32. The mounting seat 31 and the top cover 2 are connected to each other. The cover 2 is connected to facilitate the upper wiring assembly 3 to move along with the top cover 2 on the lamp holder 1. The first recess 31-a and the second recess 31-b are used to provide a sufficient setting area, which can simultaneously meet the setting requirements of the three terminal posts 33. The three terminal posts 33 are used to connect with the three-phase lines (live line, neutral line, and ground line). The setting of the first protrusion 31-c, the second protrusion 31-d, and the third protrusion 31-e can not only increase the overall length of the mounting base 31, but also simultaneously meet the setting requirements of the two conductive sheets 32, that is, the conductive sheet mounting cavities 31-f at different positions are used to place the corresponding conductive sheets 32 therein, and then the conductive sheets 32 are fixed to the mounting base 31 by the conductive posts serving as connecting components, so as to achieve contact with the terminal posts 33 used to connect the live line and the neutral line.

[0023] A third recess 31-g is formed on the mounting seat 31 between the first recess 31-a and the second recess 31-b, and first reinforcing ribs 5 distributed in a circular array with the center of the mounting seat 31 as the center are provided between the first recess 31-a and the third recess 31-g, and second reinforcing ribs 6 distributed in a circular array with the center of the mounting seat 31 as the center are provided in the second recess 31-b, and third reinforcing ribs 7 distributed in a circular array with the center of the mounting seat 31 as the center are provided between the first protrusion 31-c and the lower surface of the mounting seat 31. The structural strength of the mounting seat 31 can be increased by reinforcing ribs in multiple locations, thereby increasing the resistance of the mounting seat 31 and meeting the requirements of the user's operating component.

[0024] The lower switch assembly 4 includes a shell 41, a bottom plate 42, and three contact pins 43. The middle position of the lamp holder 1 has a fourth recess 11 for the shell 41 to be placed inside. The shell 41 has an inner sleeve 41-a for the contact pin 43 to be placed inside to quickly determine the position. One end of the contact pin 43 is placed in the inner sleeve 41-a, and the other end passes through the shell 41 upward and contacts the mounting seat 31 and the corresponding conductive sheet 32 ​​respectively. The bottom plate 42 is arranged at the bottom of the shell 41 and is provided with an elastic unit 8 with an elastic compression amount in the retraction direction of the lower switch assembly 4. The elastic unit 8 provides support for the contact pin 43 so that the contact pin 43 is maintained and installed. The housing 41 is used as a basic component to provide a clear setting position for the contact pin 43 through the inner sleeve 41-a. The bottom plate 42 is connected to the housing 41 by bolts and is used as a lower end support of the contact pin 43. It is combined with the elastic unit 8 to enable the contact pin 43 to be maintained at a fixed height, which facilitates the contact between the contact pin 43 and the conductive sheet 32 ​​and the housing 31. The elastic unit 8 raises the contact pin 43 and causes the contact pin 43 to change its height when it contacts the conductive sheet 32 ​​and the housing 31, so as to adapt to the final position of the top cover 2 covering the lamp holder 1.

[0025] The elastic unit 8 is configured as a spring whose number is the same as the number of the contact ejector pins 43, and whose two ends are supported on the bottom plate 42 and the contact ejector pins 43 respectively. The spring has a simple structure, is convenient to configure, and has a good use effect. When the contact ejector pins 43 are under pressure, the spring can be quickly compressed and deformed to adapt to the movement of the contact ejector pins 43 when under pressure, and after deformation, it generates elasticity to restore the contact ejector pins 43. The elasticity can ensure continuous contact between the contact ejector pins 43 and the conductive sheet 32 ​​and the mounting seat 31.

[0026] A contact plate 43-a is provided on the contact pin 43, and the contact plate 43-a is used to abut against the elastic unit 8. An extension channel 41-b connected to the corresponding inner sleeve 41-a is provided on the shell 41. The abutment plate 43-a passes through the extension channel 41-b to the outside of the shell 41. The abutment plate 43-a is used to increase the contact area between the contact pin 43 and the spring, so that the spring can better play its role. At the same time, considering that the contact pin 43 lacks a structure to limit its rotation in the shell 41, and the rotation will cause the spring to twist and affect the use effect of the spring, the extension channel 41-b is provided so that an opening 41-b1 is formed on the shell 41, so that the abutment plate 43-a can extend outward, and the opening 41-b1 is used to limit the abutment plate 43-a inside, thereby preventing the abutment plate 43-a from rotating, and also preventing the contact pin 43 from rotating.

[0027] A wire hole 21 for three-phase wires to enter is provided at the center of the upper end of the top cover 2. A baffle 21-a is provided at the outlet end of the wire hole 21 to provide lower support for the retaining ring 9 placed in the wire hole 21. A gap for three-phase wires to pass through is formed between the outer wall of the retaining ring 9 and the inner wall of the wire hole 21. A sealing ring 10 is inserted in the retaining ring 9. The upper section of the wire hole 21 is threadedly connected with a wire connecting sleeve 20 to prevent the retaining ring 9 from coming out. The sealing ring 10 extends into the wire connecting sleeve 20. The wire hole 31 is for three-phase wires to enter. The baffle 21-a allows a retaining ring 9 to be set inside the wire hole 21 in addition to allowing the three-phase wire to pass through. When the three-phase wire passes through, the retaining ring 9 uses its own outer wall and the inner wall of the wire hole 21 to generate a fixed restricting force on the three-phase wire, thereby preventing the three-phase wire from bending and deforming when the top cover 2 rotates, reducing the force. The sealing ring 10 has a sealing effect, thereby preventing the components placed in the top cover 2 from rapid oxidation and aging. The wire connecting sleeve 20 is used as a limiting component to prevent the retaining ring 9 from escaping from the wire hole 21.
