Description

Technical Field

[0001] The present invention relates to the technical field of cold-shrinkable cable installation, and particularly relates to a cold-shrinkable cable head and a manufacturing method thereof. Background Art

[0002] Cold-shrinkable cable is a common way to treat cable terminals. It uses a first cold-shrinkable sleeve (also known as a heat-shrinkable sleeve) to cover and protect the terminal joint part of the cable. The first cold-shrinkable sleeve is a plastic sleeve with shrinkage performance, usually made of polyolefin materials. When a heat source (such as a flame or a hot air gun) is applied, the first cold-shrinkable sleeve will shrink and tightly wrap around the cable insulator and the stranded wire. Cold-shrinkable cable is a commonly used cable terminal treatment method and is widely used in occasions where cable terminals need to be protected and connected in power systems, communication networks, and other fields.

[0003] Currently, during on-site installation of cold-shrinkable cable heads, these pre-expanded sleeves are put on the treated cable ends or joints, and the internal supporting plastic spiral strips (supports) are pulled out and pressed on the cable insulation to form a cable accessory. However, when the first cold-shrinkable sleeve is put on the cable end, in order to ensure the sealing between the subsequent shrinkage of the sleeve and the cable, since the cable end is relatively smooth, after the sleeve is put on, the operator needs to hold the sleeve tightly to prevent the sleeve from shifting when the plastic spiral strip is pulled out later. Such construction steps are rather cumbersome and prone to deviation. Based on this, the present invention designs a cold-shrinkable cable head and a manufacturing method thereof to solve the above problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cold-shrinkable cable head and a manufacturing method thereof, aiming to solve the problems raised in the above background art.

[0005] In order to achieve the above object, the present invention provides the following technical solution: A cold-shrinkable cable head includes a connection base, and a limit connection assembly is arranged on the connection base.

[0006] The limit connection assembly includes:

[0007] A plurality of cable cores, and each of the cable cores is circumferentially distributed on the connection base along the central axis point of the connection base.

[0008] A plurality of first positioning holes for limiting, and each of the first positioning holes is circumferentially distributed on the upper surface of the connection base along the central axis point of the connection base.

[0009] A plurality of first cold-shrinkable sleeves capable of shrinking, and each of the first cold-shrinkable sleeves is respectively sleeved outside the corresponding cable core.

[0010] A plurality of insulating cushions, and each of the insulating cushions is circumferentially distributed outside the corresponding first cold-shrinkable sleeve along the pivot point of the connection base.

[0011] A plurality of electrodes for connecting to electricity, and each of the electrodes is circumferentially distributed around the axis point of the connecting seat at one end of the corresponding cable core.

[0012] One end of each of the plurality of electrodes is respectively provided with a connection head for wiring. The plurality of connection heads are respectively inserted and fixed to the corresponding electrodes, and a first tightening sleeve is respectively provided at the connection between each of the first tightening sleeves and the connection head. A second tightening sleeve for limiting the first cold shrinkable sleeve is respectively provided on the outer sides of the plurality of cable cores and at one end of the first cold shrinkable sleeve.

[0013] The plurality of first positioning holes are respectively located at the bottoms of the corresponding cable cores. The plurality of limiting elastic pieces are all installed on the connecting seat. Among them, each of the corresponding first positioning holes and second positioning holes is on the same axis line.

[0014] It can be seen that in the above technical solution, when the first cold shrinkable sleeve is sleeved, the second tightening sleeve is preferably installed at the end of the first cold shrinkable sleeve. Then, the connection head is inserted into the electrode to fix the electrode and the cable core. The first tightening sleeve and the second tightening sleeve are clamped by a clamp so that the first cold shrinkable sleeve, the connection head and the cable core are fixed together.

[0015] A plurality of conductive columns for connecting to the cable, and each of the conductive columns is circumferentially distributed around the axis point of the connecting seat at the bottom end of the corresponding cable core, and each of the conductive columns respectively penetrates through the corresponding first positioning hole and extends to the bottom of the connecting seat.

[0016] A plurality of limiting elastic pieces for limiting, and each of the limiting elastic pieces is circumferentially distributed around the axis pin point of the corresponding first positioning hole on the surface of the limiting elastic piece. The plurality of limiting elastic pieces are all installed on the connecting seat.

[0017] An arc-shaped edge attachment groove with a cross-sectional shape set to be arc-shaped is respectively formed on one side of the plurality of limiting elastic pieces. A plurality of insulating rib strips for boosting protection and all matching with the arc-shaped edge attachment groove are respectively stacked on the plurality of limiting elastic pieces, and one side of each of the insulating rib strips respectively extends to the outside of the corresponding conductive column.

[0018] It can be seen that in the above technical solution, when the conductive column is inserted into the second cold shrinkable sleeve, the limiting elastic pieces outside each of the first positioning holes will respectively contact the corresponding conductive column, avoiding the displacement phenomenon when the conductive column is inserted, and there is no need for the staff to continuously press the limit with fingers, improving the convenience of the device during installation and use. And through the insulating rib strips on each of the limiting elastic pieces, the function of wrapping and clamping and limiting the conductive column is realized, and at the same time, the insulating function can also be achieved.

[0019] A second cold shrinkable sleeve for support, and the second cold shrinkable sleeve is arranged at the bottom of the connecting seat.

[0020] An extendable elastic dislocation member, which is arranged at the bottom of the second cold-shrinkable sleeve.

[0021] A number of misaligned second positioning holes, and each of the second positioning holes is circumferentially distributed along the center point of the second cold-shrinkable sleeve at the top of the second cold-shrinkable sleeve, and the plurality of second positioning holes are respectively located at the bottom of the corresponding first positioning holes.

[0022] A protective sleeve for limiting, which is arranged at the bottom of the elastic dislocation member.

[0023] A positioning ring for clamping the cable, which is arranged at the bottom of the inner cavity of the protective sleeve.

[0024] A number of first limiting grooves for limiting, and each of the first limiting grooves is circumferentially distributed along the center point of the protective sleeve at the bottom of the protective sleeve.

[0025] A number of second limiting grooves for guiding, and each of the second limiting grooves is circumferentially distributed along the center point of the protective sleeve at the top of the inner wall of the corresponding first limiting groove.

[0026] A number of locking grooves for limiting, and each of the locking grooves is circumferentially distributed along the center point of the protective sleeve at one side of the inner wall of the corresponding second limiting groove.

[0027] A number of locking blocks for limiting, and each of the locking blocks is circumferentially distributed along the center point of the positioning ring on the outside of the positioning ring.

[0028] A number of deformable elastic inclined rods for clamping the cable, and each of the elastic inclined rods is circumferentially distributed along the center point of the positioning ring inside the positioning ring.

[0029] A number of pressure-increasing protrusions for increasing friction, and each of the pressure-increasing protrusions is circumferentially distributed along the center point of the positioning ring at the top of the corresponding elastic inclined rod.

[0030] Among them, each of the locking blocks is respectively slidably connected with the corresponding first limiting groove and the second limiting groove and is engaged with the locking groove.

[0031] It can be seen that in the above technical solution, by staggering the interference between the locking block and the protective sleeve through each first limiting groove, the locking block slides in the second limiting groove, and then the positioning ring is pulled, so that each locking block can be engaged into the corresponding locking groove to limit the positioning ring in the protective sleeve. When the protective sleeve is sleeved on the end of the cable, a number of elastic inclined rods will first come into contact with the cable. At the same time, each elastic inclined rod deforms due to the traction force of the protective sleeve sleeved on the cable and the reason of the cable's own size.

[0032] A manufacturing method of a cold-shrink cable head, which includes the following steps.

[0033] Step 1, during installation, install the positioning ring in the protective sleeve. When installing the positioning ring, through each first limiting groove, the interference between the locking block and the protective sleeve is staggered, so that each locking block can be displaced into the corresponding second limiting groove. Then rotate the positioning ring, the locking block slides in the second limiting groove, and then pull the positioning ring, so that each locking block can be stuck into the corresponding locking groove to limit the positioning ring in the protective sleeve.

[0034] Step 2, when the device is in use, the staff first winds insulating and waterproof tape around the end of the cable, and then sleeved the protective sleeve on the end of the cable. When the protective sleeve is sleeved on the cable, several elastic inclined rods will first come into contact with the cable. At the same time, each elastic inclined rod deforms due to the traction force of the protective sleeve sleeved on the cable and the size of the cable itself.

[0035] Step 3, when the protective sleeve is sleeved on the outside of the cable, each pressurizing protrusion can rub against the outside of the cable. In cooperation with the elasticity of the elastic inclined rod itself, the pressurizing protrusion is driven to continuously press the cable, and the various structures on the second cold shrinkage sleeve and the connecting seat of the protective sleeve are limited to improve the stability between the protective sleeve and the cable.

[0036] Step 4, then sleeve each first cold shrinkage sleeve on the outside of the corresponding cable core. When sleeving the first cold shrinkage sleeve, first install the second tightening sleeve at the end of the first cold shrinkage sleeve, and then insert the terminal into the electrode to fix the electrode to the cable core. Clamp the first tightening sleeve and the second tightening sleeve with a clamp to fix the first cold shrinkage sleeve, the terminal and the cable core together.

[0037] Step 5, and when the cable core is installed, the cable core and the conductive column are limited by the mutually connected first positioning hole and the second positioning hole to avoid short circuit phenomena during subsequent transmission of the cable core and the conductive column. When the conductive column is inserted into the second cold shrinkage sleeve, the limiting elastic pieces outside each first positioning hole will respectively come into contact with the corresponding conductive column to avoid displacement when the conductive column is inserted, without the need for the staff to continuously press the limit with their fingers, improving the convenience of the device during installation and use.

[0038] Step 6, and through the insulating ribs on each limiting elastic piece, the function of wrapping and clamping the conductive column is realized, and at the same time, the insulating function can also be achieved. When the protective sleeve is sleeved on the cable head, through the elastic dislocation part, a certain deformation dislocation space can be provided between the second cold shrinkage sleeve and the protective sleeve, making it elastic when installed.

[0039] The present invention has the following advantages:

[0040] 1. The present invention staggers the interference between the locking blocks and the protective sleeve through each first limiting groove, enabling each locking block to be displaced into the corresponding second limiting groove. Then, by pulling the positioning ring, each locking block can be snapped into the corresponding locking groove to limit the positioning ring within the protective sleeve, facilitating the assembly of the structure by the staff. It abandons the cumbersome steps of the traditional method of extracting the internal supporting plastic spiral strip, improving the convenience of the device during use.

[0041] 2. When the protective sleeve is sleeved on the cable, several elastic inclined rods will first come into contact with the cable. At the same time, each elastic inclined rod deforms due to the traction force of the protective sleeve sleeved on the cable and the size of the cable itself. Each pressure increasing protrusion can rub against the outer side of the cable, and in cooperation with the elasticity of the elastic inclined rod itself, it drives the pressure increasing protrusion to continuously press the cable, limiting each structure on the second cold shrinkable sleeve of the protective sleeve and the connecting seat, so as to improve the stability between the protective sleeve and the cable and realize the function of automatic positioning without the need for the staff to continuously press.

[0042] 3. The present invention limits the cable core and the conductive column through the mutually connected first positioning hole and second positioning hole, avoiding the occurrence of short circuit phenomena during the subsequent transmission of the cable core and the conductive column. When the conductive column is inserted into the second cold shrinkable sleeve, the limiting elastic pieces outside each first positioning hole will respectively come into contact with the corresponding conductive column, avoiding the displacement phenomenon during the insertion of the conductive column and improving the convenience of the device during installation and use.

[0043] 4. The present invention realizes the function of wrapping and clamping the conductive column through the insulating ribs on each limiting elastic piece, and can also play an insulating role. When the protective sleeve is sleeved on the cable head, the elastic misalignment member enables a certain deformation misalignment space between the second cold shrinkable sleeve and the protective sleeve, making it elastic during installation.

[0044] In summary, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, it facilitates the assembly of the structure by the staff, abandons the cumbersome steps of the traditional method of extracting the internal supporting plastic spiral strip, improves the convenience of the device during use, enables a certain deformation misalignment space between the second cold shrinkable sleeve and the protective sleeve through the elastic misalignment member, making it elastic during installation, realizes the function of automatic positioning without the need for the staff to continuously press, and has good practicability while being convenient to use.

A plurality of second positioning holes 302 are respectively located at the bottoms of the corresponding first positioning holes 102.

[0072] A protective sleeve 303 for limiting, and the protective sleeve 303 is arranged at the bottom of the elastic misalignment member 301.

[0073] A positioning ring 304 for clamping the cable, and the positioning ring 304 is arranged at the bottom of the inner cavity of the protective sleeve 303.

[0076] A number of locking grooves 307 for limiting, and each locking groove 307 is circumferentially distributed along the center point of the protective sleeve 303 on one side of the inner wall of the corresponding second limiting groove 306.

[0077] A number of locking blocks 308 for limiting, and each locking block 308 is circumferentially distributed along the center point of the positioning ring 304 on the outside of the positioning ring 304.

[0078] A number of elastic inclined rods 309 that can deform and are used to clamp the cable, and each elastic inclined rod 309 is circumferentially distributed along the center point of the positioning ring 304 inside the positioning ring 304.

[0079] A number of pressure - increasing protrusions 310 for increasing friction, and each pressure - increasing protrusion 310 is circumferentially distributed along the center point of the positioning ring 304 at the top of the corresponding elastic inclined rod 309.

[0080] Among them, each locking block 308 is respectively slidably connected to the corresponding first limiting groove 305 and is clamped with the locking groove 307 in the second limiting groove 306.

[0081] When used according to the above structure, during installation, the positioning ring 304 is installed inside the protective sleeve 303. When installing the positioning ring 304, the interference between the locking block 308 and the protective sleeve 303 is staggered through each first limiting groove 305, so that each locking block 308 can be displaced into the corresponding second limiting groove 306. Then, the positioning ring 304 is rotated, and the locking block 308 slides in the second limiting groove 306. Then, the positioning ring 304 is pulled, so that each locking block 308 can be snapped into the corresponding locking groove 307 to limit the positioning ring 304 inside the protective sleeve 303. The staff first wraps an insulating and waterproof tape around the end of the cable, and then sleevs the protective sleeve 303 on the end of the cable. When the protective sleeve 303 is sleeved on the cable, a number of elastic inclined rods 309 will first come into contact with the cable.

[0082] When the protective sleeve 303 is sleeved outside the cable, each pressurizing protrusion 310 can rub against the outside of the cable. Coupled with the elasticity of the elastic inclined rod 309 itself, the pressurizing protrusion 310 is driven to continuously press the cable, so as to limit each structure on the second cold-shrinkable sleeve 3 of the protective sleeve 303 and the connecting seat 1, so as to improve the stability between the protective sleeve 303 and the cable. Then, each first cold-shrinkable sleeve 103 is sleeved outside the corresponding cable core 101. When the first cold-shrinkable sleeve 103 is sleeved, the second tightening sleeve 108 is preferably installed at the end of the first cold-shrinkable sleeve 103. Then, the terminal 107 is inserted into the electrode 105 to fix the electrode 105 and the cable core 101. The first tightening sleeve 106 and the second tightening sleeve 108 are clamped by a clamp to fix the first cold-shrinkable sleeve 103, the terminal 107 and the cable core 101 together.

[0083] And when the cable core 101 is installed, the cable core 101 and the conductive column 2 are limited by the mutually connected first positioning hole 102 and the second positioning hole 302, so as to avoid short-circuit phenomena when the cable core 101 and the conductive column 2 are transmitting later. When the conductive column 2 is inserted into the second cold-shrinkable sleeve 3, the limiting elastic pieces 201 outside each first positioning hole 102 will respectively contact the corresponding conductive column 2, so as to avoid the displacement phenomenon when the conductive column 2 is inserted, without the need for the staff to continuously press with their fingers, improving the convenience of the device during installation and use. And through the insulating ribs 203 on each limiting elastic piece 201, the function of wrapping and clamping the conductive column 2 is realized, and at the same time, the insulating function can also be achieved. When the protective sleeve 303 is sleeved on the cable head, the elastic misalignment member 301 enables a certain deformation misalignment space to exist between the second cold-shrinkable sleeve 3 and the protective sleeve 303, making it elastic when installed.

[0084] Different from the prior art, the present application discloses a cold-shrinkable cable head and its manufacturing method. Through the corresponding cooperation of each structure, it is convenient for the staff to assemble the structure, abandoning the cumbersome steps of the traditional extraction of the internal support plastic spiral strip, improving the convenience of the device during use. The elastic misalignment member 301 enables a certain deformation misalignment space to exist between the second cold-shrinkable sleeve 3 and the protective sleeve 303, making it elastic when installed, realizing the function of automatic positioning, without the need for the staff to continuously press, being convenient to use and having good practicability.

[0085] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
