Description

Technical Field

[0001] The invention relates to the technical field of power lines, and in particular to a cable joint reinforcement structure. Background Art

[0002] Cables used to transmit signals or currents are widely used. In power tests, quick-plug terminals are often used to connect cables to metering devices for outputting signals and collecting status, and they are removed after the test.

[0003] In the prior art, the cable joints used in metering devices are usually made of cylindrical conductors and round tube conductors. Adding a circle of elastic structure to the outer ring of the cylindrical conductor can not only increase the contact area between the two, but also strengthen the connection strength between the two through the friction between the elastic sheet and the inner wall of the round tube conductor. However, it is still easy to fall off during use, especially in vertical upward application scenarios, where it is difficult to achieve fastening by friction alone. Summary of the invention

[0004] The object of the present invention is to provide a cable joint reinforcement structure, which can improve the stability of cable connection and effectively prevent the cable from slipping off.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] Provided is a cable joint reinforcement structure, comprising:

[0007] A male plug, comprising a male plug body, an elastic sheet and a sliding member, wherein the male plug body is configured to be connected to a cable, the elastic sheet is sleeved on the male plug body, a fixing member is convexly provided at an end of the male plug body away from the cable along a circumferential direction, the sliding member is slidably sleeved on the male plug body and is located between the elastic sheet and the fixing member, and a first inclined surface is provided on the sliding member, and the first inclined surface is inclined in a direction toward the cable;

[0008] The female plug is configured to be fixed on the metering device, and is provided with an insertion cavity allowing the male plug to be inserted. The elastic sheet can abut against the side wall of the insertion cavity. A side locking piece is passed through the side wall of the insertion cavity. The side locking piece is slidably arranged on the metering device in a direction perpendicular to the axis of the insertion cavity. The end of the side locking piece extending into the insertion cavity is provided with a second inclined surface, and the second inclined surface is inclined in the direction toward the male plug.

[0009] As an optional solution for the cable connector reinforcement structure, a first fixing portion is protruded from the outer wall of the side locking member, and a first elastic member is sleeved on the portion of the side locking member that does not extend into the plug-in cavity. The first elastic member is connected between the first fixing portion and the metering device.

[0010] As an optional solution for the cable joint reinforcement structure, a plurality of side locking members are arranged at intervals along the circumference of the plug-in cavity.

[0011] As an optional solution for the cable connector reinforcement structure, an abutment piece is provided on the bottom wall of the plug-in cavity, and the abutment piece is slidably arranged on the metering device along the axial direction of the plug-in cavity, and the abutment piece can abut against the fixing piece.

[0012] As an optional solution for the cable connector reinforcement structure, a second fixing portion is protruded from the outer wall of the abutment member, and a second elastic member is sleeved on the portion of the abutment member that does not extend into the plug-in cavity. The second elastic member is connected between the second fixing portion and the metering device.

[0013] As an optional solution to the cable joint reinforcement structure, the abutment piece is made of insulating material.

[0014] As an optional solution for the cable joint reinforcement structure, the sliding member and the side locking member are both made of insulating material.

[0015] As an optional solution for the cable connector reinforcement structure, a stopper is further sleeved on the male plug body, and the stopper is located between the elastic sheet and the sliding member.

[0016] As an optional solution for the cable connector reinforcement structure, a plurality of elastic sheets are arranged at intervals along the circumference of the male plug body.

[0017] As an optional solution for the cable joint reinforcement structure, a circular chamfer is provided at one end of the fixing member away from the sliding member.

[0018] Beneficial effects of the present invention:

[0019] The present invention provides a cable joint reinforcement structure, wherein a male plug is inserted into a plug-in cavity of a female plug, and an elastic sheet is elastically deformed under its own elastic action, and is conductively connected to the female plug; a fixing piece at the end of the male plug body abuts against a second inclined surface of a side locking piece, and during the process of plugging the male plug body inward, the fixing piece slides along the second inclined surface and pushes open the side locking piece, so that the side locking piece extends between the fixing piece and the sliding piece, so as to limit the male plug in the plug-in cavity, prevent the male plug from slipping out of the plug-in cavity of the female plug, and improve the stability of the connection at the cable joint. Even if the male plug is pulled outward, it cannot be pulled out of the plug-in cavity due to the restriction of the side locking piece.

[0020] When the male plug needs to be pulled out, it is necessary to continue to push the male plug in the direction toward the plug-in cavity, so that the side locking member pushes the sliding member to move until the sliding member is stopped by the elastic sheet and cannot move further. At this time, under the guidance of the second inclined surface, the side locking member will pass over the sliding member and slide along the first inclined surface to slide between the elastic sheet and the sliding member. Then the male plug is pulled outward, and under the push of the side locking member, the sliding member will slide in the direction close to the fixing member until it abuts against the fixing member. Under the guidance of the first inclined surface, the side locking member is pushed open so that the male plug can be pulled out smoothly. In other words, when installing, just insert the male plug into the plug-in cavity; and when pulling it out, it is necessary to push it into the inside of the plug-in cavity first, and then pull it out. The operation is convenient and quick, and the stability of the connection can be ensured even in a vertical upward installation scenario. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figures 1 to 5As shown, this embodiment provides a cable joint reinforcement structure, including a male plug 1 and a female plug 2, wherein the male plug 1 includes a male plug body 11, an elastic sheet 12 and a sliding member 13, the male plug body 11 is configured to be connected to the cable 100, the elastic sheet 12 is sleeved on the male plug body 11, the end of the male plug body 11 away from the cable 100 is convexly provided with a fixing member 14 along the circumferential direction, the sliding member 13 is slidably sleeved on the male plug body 11, and is located between the elastic sheet 12 and the fixing member 14. The female plug 2 is configured to be arranged on the metering device, the female plug 2 is provided with an insertion cavity 20 allowing the male plug 1 to be inserted, the elastic sheet 12 can abut against the side wall of the insertion cavity 20, the side wall of the insertion cavity 20 is penetrated with a side locking member 3, and the side locking member 3 is slidably arranged on the metering device along a direction perpendicular to the axis of the insertion cavity 20. The sliding member 13 is provided with a first inclined surface 130, which is inclined in the direction toward the cable 100; the end of the side locking member 3 extending into the insertion cavity 20 is provided with a second inclined surface 30, which is inclined in the direction toward the male plug 1. When the male plug 1 is inserted into the insertion cavity 20 of the female plug 2, the elastic sheet 12 undergoes elastic deformation under its own elastic action and is electrically connected to the female plug 2; the fixing member 14 at the end of the male plug body 11 abuts against the second inclined surface 30 of the side locking member 3. During the process of inserting the male plug body 11 inwardly, the fixing member 14 slides along the second inclined surface 30 and pushes open the side locking member 3, so that the side locking member 3 extends between the fixing member 14 and the sliding member 13, that is, Figure 2 As shown, the male plug 1 is limited in the insertion cavity 20 to prevent the male plug 1 from slipping out of the insertion cavity 20 of the female plug 2, thereby improving the stability of the connection at the joint of the cable 100. Even if the male plug 1 is pulled outward, it cannot be pulled out of the insertion cavity 20 due to the restriction of the side locking member 3.

[0039] When the male plug 1 needs to be pulled out, the male plug 1 is pushed toward the insertion cavity 20, so that the side lock member 3 pushes the sliding member 13 to move until the sliding member 13 is stopped by the elastic sheet 12 and cannot move further. At this time, under the guidance of the second inclined surface 30, the male plug 1 is pushed toward the insertion cavity 20, so that the side lock member 3 pushes the sliding member 13 to move. Figure 3 , the side lock member 3 will pass over the sliding member 13 and slide along the first inclined surface 130 to slide between the elastic sheet 12 and the sliding member 13. Then the male plug 1 is pulled outward, and under the pushing action of the side lock member 3, the sliding member 13 will slide in the direction close to the fixing member 14 until it abuts against the fixing member 14. Figure 4 and Figure 5 Under the guidance of the first inclined surface 130, the side lock member 3 is pushed open so that the male plug 1 can be pulled out smoothly. That is to say, when installing, just insert the male plug 1 into the plug cavity 20; when pulling out, you need to push it into the plug cavity 20 first, and then pull it out. The operation is convenient and quick, and the stability of the connection can be ensured even in a vertical installation scenario.

[0040] Specifically, the sliding member 13 is annular and sleeved on the male plug body 11, and the first inclined surface 30 is circumferentially arranged on the sliding member 13. That is, the diameter of the sliding member 13 near the fixing member 14 is larger than the diameter of the sliding member 13 near the elastic sheet 12.

[0041] Exemplarily, the side locking member 3 is a spring pin commonly used in the art, and has good elasticity to improve the stability of the side locking member 3 between the fixing member 14 and the sliding member 13 .

The above arrangement can further enhance the stability of the side lock member 3 under the elastic action of the first elastic member 32, and prevent the side lock member 3 from sliding in a direction perpendicular to the axis of the plug-in cavity 20 under external force disturbance.

[0045] Specifically, the first elastic member 32 is a spring commonly used in the art, has good elasticity, is easy to obtain, and is economical.

[0046] Optionally, the sliding member 13 and the side locking member 3 are both made of insulating materials to avoid conductive connection with the male plug body 11 and ensure safety during use. Specifically, the insulating material is a prior art in the art and is not specifically limited here.

[0047] Optionally, a stopper 15 is further sleeved on the male plug body 11 . The stopper 15 is located between the elastic sheet 12 and the sliding member 13 and is used to limit the sliding range of the elastic member.

[0048] Optionally, an abutment member 4 is provided on the bottom wall of the plug cavity 20, and the abutment member 4 is slidably arranged on the metering device along the axial direction of the plug cavity 20, and the abutment member 4 can abut against the fixing member 14. The above arrangement can provide tactile feedback to the user, so that the user can feel the position of the male plug 1. Exemplarily, the abutment member 4 is also a spring pin.

Exemplarily, the second elastic member 42 is also a spring.

[0050] Optionally, the abutment member 4 is made of insulating material to prevent conductive connection between the abutment member 4 and the male plug body 11, thereby ensuring safety during use. Specifically, the insulating material is a prior art in the art and is not specifically limited here.

[0051] Optionally, a plurality of elastic sheets 12 are provided along the circumference of the male plug body 11 to further increase the contact area between the male plug body 11 and the inner wall of the limiting cavity of the female plug 2, increase the contact friction between the two, and ensure good conductivity.
