Description

[Technical field]

[0002] The invention relates to the technical field of cable connectors, in particular to a push-type self-locking waterproof connection mechanism. [Background technology]

[0004] With the continuous development of science and technology, people's work and life are inseparable from electricity. In order to facilitate the use of electricity, people have created a variety of suitable connectors, but there are many disadvantages: most of the current connectors use threaded self-locking, plug-in external buckle self-locking or torsion spring self-locking, but the buckle parts are all on the outer surface of the connector. Long-term exposure to ultraviolet rays outdoors accelerates its aging. It is difficult to clearly know whether the assembly of the threaded self-locking connector is in place during assembly. If the assembly is not in place, the sealing ring will not be able to play a good sealing role, resulting in poor waterproof effect and cannot be used for outdoor wiring work.

[0019] Furthermore, a third sealing ring is provided on the end surface of the plug-in portion.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention includes a female connector and a male connector, wherein the male connector includes a plug-in portion, and a sealing ring and a locking portion for clamping are arranged on the outer peripheral surface of the plug-in portion. When the plug-in portion enters the insertion cavity of the female connector, a seal is formed between the sealing ring and the inner cavity wall of the female connector. At the same time, the elastic self-locking plug-in mechanism cooperates with the locking portion on the plug-in portion, so that the male connector can be clamped in the female connector, thereby ensuring that the male connector and the female connector are assembled in place, and the sealing ring can be well fixed to ensure a good sealing effect. The elastic self-locking plug-in mechanism can also be moved by pressing to disengage it from the locking portion, and the male connector is It can be disassembled from the female connector, which is convenient to disassemble and can achieve fast and effective assembly and disassembly.

Therefore, after the plug-in, the external water cannot enter the interior through the gap between the male connector and the female connector, and the sealing effect is better;

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Please refer to Figures 1 to 13 As shown, a push-type self-locking waterproof connection mechanism includes a female connector 1 and a male connector 2, the inner cavity of the female connector 1 is provided with a first through hole 3 for installing a conductive column, the male connector 2 is provided with a second through hole 4 for the conductive column to pass through to achieve electrical conduction relative to the first through hole 3, the male connector 2 is provided with a plug-in portion 21, the female connector 1 is provided with an insertion cavity 101 for the insertion portion 21 to enter, a sealing ring 5 is provided between the outer peripheral surface of the plug-in portion 21 and the inner cavity wall of the female connector 1, the female connector 1 is provided with a push-type elastic self-locking mechanism 8 inserted into the insertion cavity 101 from the side wall of the female connector 1, and the plug-in portion 21 is provided with a locking portion 7 that cooperates with the push-type elastic self-locking mechanism 8.

[0050] The present invention comprises a female connector and a male connector, wherein the male connector comprises an inserting portion, and a sealing ring and a locking portion for locking are arranged on the outer peripheral surface of the inserting portion. When the inserting portion enters the insertion cavity of the female connector, a seal is formed between the sealing ring and the inner cavity wall of the female connector. At the same time, an elastic self-locking plug-in mechanism cooperates with the locking portion on the inserting portion, so that the male connector can be locked in the female connector, thereby ensuring that the male connector and the female connector are assembled in place, and the sealing ring can be well fixed to ensure a good sealing effect. The elastic self-locking plug-in mechanism can also be moved by pressing to disengage it from the locking portion, and the male connector can be It is easy to disassemble from the female connector, and can achieve fast and effective assembly and disassembly. Therefore, the present invention can simultaneously have the functions of waterproofing and easy disassembly, so that it can be used for outdoor wiring work for a long time. Since the movable elastic self-locking plug-in mechanism can be inserted into the locking part after self-locking, it has better tensile performance after assembly. The press-type elastic self-locking mechanism is inserted into the cavity from the side wall of the female connector. Therefore, the locking parts are all hidden in the connecting mechanism to prevent outdoor ultraviolet radiation. Compared with the existing connectors, the performance is improved, the assembly process is more accurate and fast, and the sealing effect is good.

[0051] Preferably, the elastic self-locking plug-in mechanism 8 includes a clamping member 82 which is provided on the female connector 1 and extends into the insertion cavity 101 and can move radially, and a spring 81 which is provided between the clamping member 82 and the female connector 1. The clamping member 82 is also provided with a clamping member through hole 84 for the plug-in portion 21 to pass through. The inner wall of the clamping member through hole 84 is also provided with a clamping portion 83. When the male connector 2 is connected to the female connector 1, the clamping portion 83 is clamped in the first groove 7. Figure 3 and Figure 4 As shown, a spring 81 is provided on the outer surface of the female connector 1, and a clamping member 82 is provided on the spring 81. The clamping member through hole 84 on the clamping member 82 is connected to the through hole of the female connector 1 so that the male connector can be inserted, and a clamping portion 83 is extended from the inner wall of the clamping member through hole 84 toward the through hole of the female connector 1, and the clamping portion 83 can slightly block the through hole of the female connector 1, so that when the male connector 2 enters the female connector 1, the spring 81 is compressed and the clamping member 82 moves along the compression direction of the spring 81 (i.e., moves upward), so that the clamping member 82 drives the clamping portion 83 to open the through hole of the female connector 1, until the male connector 2 completely enters the female connector 1, the spring 81 recovers its deformation, and the clamping member 82 drives the clamping portion 83 to move downward, so that the clamping portion 83 enters the first groove 7 of the male connector 2 for fixing. Of course, when disassembling, the spring 81 can be compressed to pull out the male connector 2. Therefore, the present invention is easy to disassemble and can achieve fast and effective assembly and disassembly, and is equipped with a device that can further enhance the tensile strength.

[0052] Preferably, the clamping portion 83 is provided with a circular arc chamfer 831 on one side opposite to the male connector 2. Figure 7 and Fig. 9As shown, the clamping portion 83 is provided with an arc-shaped chamfer 831 on the side where the male connector 2 enters the female connector 1. The chamfer 831 has a guiding function, so that when the male connector 2 enters the female connector 1, the male connector 2 squeezes the chamfer 831 to force the clamping member 82 to move upward, further making the installation more convenient and faster, and the assembly easier and more convenient.

[0053] Preferably, the cross section of the insertion cavity 101 is a trumpet-shaped shape with a diameter gradually increasing from the inside to the end opening side, the plug-in portion 21 is provided with a conical surface 211 consistent with the taper direction of the insertion cavity 101, and a second sealing ring 17 is provided between the outer side of the conical surface 211 and the inner wall of the insertion cavity 101.

Since the diameter of the plug-in portion of the sealing ring 5 is larger than the outermost diameter of the female connector 1, after the male connector 2 enters along the inclined surface, the sealing ring 5 is gradually squeezed and deformed, so that sealing in the radial direction can be achieved. Since the sealing ring 5 extends more inwardly, the greater the deformation of the sealing ring 5, after the sealing ring 5 is deformed, it deforms toward the blocking portion 6 or even deforms to contact with the blocking portion 6, so that sealing in the axial direction can be achieved, thereby achieving a two-way waterproof function. Since the inclination direction of the second sealing ring 17 is consistent with the inclination direction of the female connector 1, the second sealing ring 17 is compressed after the male connector 2 enters the female connector 1 to further enhance the sealing effect. At the same time, the conical surface 211 of the plug-in portion 21 can make it easier to enter the cavity 101.

When the male connector 2 completely enters the female connector 1, the axial sealing portion 51 contacts the blocking portion 6 and is compressed to seal and waterproof the axial direction. The cross-sectional area of ​​the sealing ring 5 also extends radial sealing portions 52 in radial directions on both sides. When the male connector 2 completely enters the female connector 1, the radial sealing portion 52 contacts the inner wall of the inserted cavity and is compressed to seal and waterproof the radial direction, thereby achieving a two-way waterproof function.

[0056] Preferably, a positioning partition plate 13 extending from the bottom toward the port is provided in the insertion cavity 101, and the male connector 2 is provided with a positioning groove 14 matching the positioning partition plate 13. The height of the positioning partition plate 13 is higher than the conductive column to prevent the conductive columns on both sides from falling and short-circuiting after conductive objects fall, and also to enable the male connector and the female connector to be accurately installed.

[0057] Preferably, a foolproof positioning block 15 is provided on one side of the positioning partition plate 13, and a foolproof positioning groove 16 matching the key strip 15 of the foolproof positioning block 15 is provided on the positioning groove 14 to ensure that the insertion method is unique when the male and female are combined to prevent the positive and negative power supply from being inserted in reverse and burning the equipment.

[0058] Preferably, the locking portion 7 is a locking groove, which has a simple structure and is easy to produce.

[0059] Preferably, a mounting portion 9 is provided on the outer peripheral surface of the female connector 1, a hollow hole 10 connected to the through hole of the female connector 1 is provided on one side of the mounting portion 9, an insertion groove 11 for the clip 82 to pass through is provided between one side of the mounting portion 9 and the through hole of the female connector 1, and the mounting portion 9 is also provided with a first chamber 12 connected to the insertion groove 11 for the clip 82 to move up and down. The mounting portion 9 can enhance the overall appearance and facilitate the production and installation of the clip 82, which is conducive to improving production efficiency.

[0060] The present application also includes a third embodiment, in which the end surface of the plug-in portion 21 is provided with a third sealing ring

[0061] 18, so that the plug-in portion 21 drives the third sealing ring 18 to enter the insertion cavity 101, and the third sealing ring 18 is squeezed, so that the inside and the outside are further isolated, and the double sealing protection further improves the sealing effect.

[0062] As the plug-in part is inserted into the cavity, the air is compressed in the female connector.

[0063] The air collected in the joint and the cavity will generate positive pressure, so the external water will not be

[0064] It is impossible to enter the interior from the gap between the male connector and the female connector, and the sealing effect is better.

[0065] The present application also includes a fourth embodiment, in which the female connector 1 is provided with a second push-type elastic self-locking mechanism 22 inserted into the locking portion 7 from the side wall of the other side of the female connector 1, and the second push-type elastic self-locking mechanism 22 includes a second clamping member 221 provided on the female connector 1 and extending into the insertion cavity 101 and capable of radial movement, and a second spring 222 provided between the second clamping member 221 and the female connector 1, and a second clamping member through hole 223 is also provided on the second clamping member 221 for the insertion portion 21 to pass through, and a second clamping member 224 is also protruding from the inner wall of the second clamping member through hole 223, when the male connector 2 is connected to the female connector 1, the second clamping member 224 is clamped in the locking portion 7, and a travel cavity 225 for radial movement of the clamping member 82 is provided between the inner side of the second clamping member 221 and the clamping member 82, as shown in FIG. Fig.13 As shown, the present application is also provided with a second push-type elastic self-locking mechanism 22 having a structure consistent with the push-type elastic self-locking mechanism. Since the second push-type elastic self-locking mechanism and the push-type elastic self-locking mechanism are arranged on both sides of the female connector 1 relatively, after the user presses the two mechanisms at the same time, the second clip 221 and the clip 82 move radially at the same time, and the user can insert the male connector into the female connector until the male connector is fully inserted into the female connector, and then the second clip 221 and the clip 82 are reset under the action of their respective connected springs and are simultaneously snapped into the locking portion 7, further enhancing the fixing effect and preventing the male connector from shaking due to poor fixing effect, thereby affecting the sealing effect.

[0066] Working principle: When the user presses the clamping piece of the female connector, the spring is compressed, and the clamping piece drives the clamping part to move upward, so that the male connector can enter the female connector.

The elastic self-locking plug-in mechanism can also be moved by pressing to disengage it from the locking portion, and the male connector can be It is easy to disassemble from the female connector, and can achieve fast and effective assembly and disassembly. Therefore, the present invention can simultaneously have the functions of waterproofing and easy disassembly, so that it can be used for outdoor wiring work for a long time. Since the movable elastic self-locking plug-in mechanism can be inserted into the locking part after self-locking, it has better tensile performance after assembly. The press-type elastic self-locking mechanism is inserted into the cavity from the side wall of the female connector. Therefore, the locking parts are all hidden in the connecting mechanism to prevent outdoor ultraviolet radiation. Compared with the existing connectors, the performance is improved, the assembly process is more accurate and fast, and the sealing effect is good.
