Optionally, the two-core cable 8 may further include a shielding layer 83. The shielding layer 83 is used to shield the cable from radiation interference to other surrounding electrical equipment. The shield 83 may be fitted over the two cables 82 between the sheath 81 and the insulating cover 821.

Fig. 2-4 are schematic structural diagrams of a connection terminal provided in an embodiment of the present disclosure. Referring to fig. 2 to 4, each connection terminal 1 includes a mounting plate 11, a cable mounting sleeve 12 for mounting a cable, and a connection mechanism 13.
The cable mounting sleeve 12 is arranged on the front side of the mounting plate 11 and the connection means 13 is arranged on the rear side of the mounting plate 11.
The connecting mechanism 13 includes a core rod 131 and a core sleeve 132 for connecting the cable cores.
The core rod 131 and the core sleeve 132 are disposed on opposite sides of the mounting plate 11, respectively.
The core rod 131 is inserted into the mounting plate 11, and one end of the core rod 131 is located in the cable mounting sleeve 12.
The core sleeve 132 is provided with a through hole 133, and the through hole 133 is communicated with the cable mounting sleeve 12.
The core rod 131 of one of the connection terminals 1 is fitted into the through hole 133 of the core housing 132 of the other connection terminal 1.
In the embodiment of the present disclosure, the cable connection device includes two connection terminals 1, each connection terminal 1 includes a mounting plate 11, a cable mounting sleeve 12 and a connection mechanism 13, the cable mounting sleeve 12 is disposed on the front surface of the mounting plate 11, and the connection mechanism 13 is disposed on the back surface of the mounting plate 11; the cable connecting sleeve is used for installing a cable; the connecting mechanism 13 comprises a core rod 131 and a core sleeve 132, the core rod 131 and the core sleeve 132 are respectively arranged on two opposite sides of the mounting plate 11, the core rod 131 is inserted in the mounting plate 11, and one end of the core rod 131 is positioned in the cable mounting sleeve 12; one end of the core rod 131 can be connected with a cable core positioned in the cable mounting sleeve 12; the core sleeve 132 is provided with a through hole 133, and the through hole 133 is communicated with the cable installation sleeve 12; the core rod 131 of one of the connection terminals 1 is matched with the through hole 133 on the core sleeve 132 of the other connection terminal 1; the other end of the core rod 131 can be connected to the cable core of the cable attached to the other connection terminal 1, and the core sleeve 132 can isolate the core rod 131 when the core rod 131 is positioned in the through hole 133; in this way, the core rod 131 on one of the connection terminals 1 can butt-joint one cable core of the cables mounted on both connection terminals 1; the core rod 131 on the other connection terminal 1 can butt-joint the other cable core of the cable mounted on the two connection terminals 1; the core rods 131 of the two connection terminals 1 are separated by the mating core sleeves 132, and the electrical connection of the two-core cable is realized.
In addition, the two connecting terminals 1 have the same structure, so that a manufacturer can only prepare one set of die to produce the connecting terminals 1, thereby saving the production cost; meanwhile, when two cables are connected, because the two butted connecting terminals 1 have the same structure, the types of the two butted connecting terminals 1 do not need to be distinguished, and any two ends of any two cables in the cables provided with the connecting terminals 1 can be mutually connected, thereby bringing convenience to cable connection and improving the cable connection efficiency.
The cable mounting sleeve 12 is used to mount one end of a cable. Alternatively, the cable mounting sleeve 12 may be of cylindrical construction.
The cable mounting sleeve 12 may be made of a hard insulating material, and can perform an insulating protection function on the cable.
The mounting plate 11 is used as a mounting substrate for the cable mounting sheath 12 and the connection mechanism 13. Alternatively, the mounting plate 11 may be a semicircular plate, which may be half the size of the cross-section of the cable mounting sleeve 12. The mounting plate 11 is fixedly connected to the cable mounting sleeve 12 as an end face of one end of the cable mounting sleeve 12, and a semicircular gap is formed between the straight edge of the mounting plate 11 and the cable mounting sleeve 12.
The mounting plate 11 may be made of a hard insulating material, and may perform insulating and supporting protection functions.
Alternatively, the cable mounting sleeve 12 and the mounting plate 11 may be of unitary construction.
The core sleeve 132 is used to cover the core rod 131 (the core rod 131 is located in the through hole 133) to separate the two core rods 131 of the two connection terminals 1. A large gap may exist between the core cases 132 of the two connection terminals 1, or may be attached together. Illustratively, the core housings 132 of the two connection terminals 1 are in contact. Thus, the gap between the core cases 132 of the two connection terminals 1 is very small, and other objects are prevented from falling into the gap between the core cases 132, so that the two connection terminals 1 can be closely attached to form a whole.
Accordingly, the core sleeve 132 may have a semi-cylindrical structure, the size of the cross section of the core sleeve 132 may be the same as that of the mounting plate 11, the core sleeve 132 is axially installed at the semicircular gap, and the core sleeve 132 is concentric with the cable mounting sleeve 12 (the axial direction of the core sleeve 132 is in the same direction as the axial direction of the cable mounting sleeve 12, and the circular arc-shaped peripheral wall of the core sleeve 132 is located on the same circular arc surface as the peripheral wall of the cable mounting sleeve 12).
The core sleeve 132 may be made of a hard insulating material, and may serve to insulate and protect the core rod 131.
The core rod 131 is used to connect the cable cores of two cables and to connect the two cables.
Accordingly, the core rod 131 can be inserted onto the mounting plate 11 in the axial direction of the cable mounting sleeve 12, and the positions of the through holes 133 on the core rod 131 and the core sleeve 132 correspond to the cable cores of the cables to be mounted, respectively. The mandrel 131 is clearance fitted with the through hole 133.
The core rod 131 may be made of a conductive metal, which has a high power transmission performance.
When the cable is connected through the cable connecting device, firstly, the flatness of one end of the cable is checked (the end surface of the cable can be shown as figure 1); then one end of the cable is installed into a cable connection sleeve of one connection terminal 1; finally, connecting terminal 1 at any end of one cable is connected with connecting terminal 1 at any end of the other cable (core rod 131 is inserted into through hole 133), and the connection of the two cables is completed. In the connection process, the sheath, the insulating sleeve and the shielding layer of the cable do not need to be stripped, so that the connection efficiency of the cable is improved.
Among the problems of electromagnetic compatibility, cables tend to be a weak link of the entire system. In an actual EMI (Electromagnetic Interference) test, it is sometimes found that the independent devices are not qualified after being connected to each other through cables to form a system when the independent devices are qualified, mainly because of cable radiation. The mutual connection of the cables increases the risk of the electromagnetic compatibility problem, and the main reason is that the shielding layers of different cables at the connection part cannot form effective lap joints and lose the shielding effect. In view of the problem of electromagnetic compatibility of the connection cable, in the cable connection device provided in the present embodiment, each connection terminal 1 further includes a shield member 14 for connecting with the shield layer of the cable, and the shield member 14 is disposed on the core sleeve 132 in a manner surrounding the through hole 133.
The purpose of the shield assembly 14 is to provide shielding at the junction of two cables to reduce cable emissions.
The present embodiment does not limit the structure of the shielding assembly 14, and alternatively, when the core sleeve 132 has a semi-cylindrical structure, the shielding assembly 14 may be a C-shaped plate, and the C-shaped plate is wrapped on the circular arc-shaped peripheral wall of the core sleeve 132. The C-shaped plates of the two connection terminals 1 can be butted and form a cylinder of the same size as the shielding layer of the cable.
The material of the shield assembly 14 may be the same as the material of the shield layer of the cable to effectively overlap the shield layer of the cable.
Still alternatively, the shielding assembly 14 includes a shielding half ring 141 and a closure ring 142.
The shield half ring 141 is provided on the core sleeve 132 and arranged around the through hole 133.
The closure ring 142 comprises a shielding shoe 143 and a shielding collar 144 for contacting the shielding layer of the cable.
The shield shoe 143 is disposed on the core housing 132 and arranged around the through hole 133, and the shield half ring 141 is fitted to a first end of the shield shoe 143.
A shield ring 144 is provided on the mounting plate 11, the shield ring 144 comprising a first half-ring 145 and a second half-ring connected (the second half-ring being covered by the core sleeve 132), the first half-ring 145 being arranged around the core rod 131.
The second end of the shield shoe 143 abuts the second half turn.
The first half-turn 145 of one of the connection terminals 1 abuts against the shield half-turn 141 of the other connection terminal 1, and the shield shoe 143 of one of the connection terminals 1 is clearance-fitted with the shield shoe 143 of the other connection terminal 1.
Fig. 5 is a schematic structural diagram of the shielding half-ring 141 according to the embodiment of the present disclosure. Referring to fig. 5, the shield half ring 141 has a semicircular structure having a diameter smaller than that of the cross-section of the core sleeve 132.
The purpose of the shielding half-ring 141 is to provide a shielding effect at the junction of the two connection terminals 1 (when the two connection terminals 1 are connected, the shielding half-ring 141 of one connection terminal 1 will abut the first half-ring 145 of the other connection terminal 1).
In the closed ring 142, the purpose of the shielding shoe 143 is to be able to provide a shielding effect at the peripheral walls of the two connection terminals 1 (arranged around the through-hole 133, providing a shielding effect for the core rod 131 within the through-hole 133).
Compared to the structure of the C-type board, since the shielding effect is provided at the junction of the two connection terminals 1, the shielding effect is stronger. Meanwhile, the structure of the above-described shield assembly 14 is the same for each of the connection terminals 1, ensuring that each of the connection terminals 1 has the same structure.
Illustratively, the closure ring 142 is a unitary structure.
Illustratively, the shielding half 141 is a rubber half (e.g., a conductive rubber half), and the closing ring 142 is a metal ring (e.g., a conductive metal ring).
By the shielding assembly 14, the shielding layers of the two connected cables can be connected with each other, so that the shielding effect of the joint is increased, and the radiation of the cables is reduced.
In the related art, the condition of loose cable connection exists, which easily causes safety accidents and seriously affects factory production. In this regard, in the present embodiment, the core housings 132 of the two connection terminals 1 are detachably connected, for example.
By detachably connecting the core covers 132 of the two connection terminals 1, the connection firmness of the two connection terminals 1 can be further enhanced while the core rod 131 is in clearance fit with the through hole 133.
The present embodiment does not limit the connection manner of the core cases 132 of the two connection terminals 1, and alternatively, the core cases 132 of the two connection terminals 1 may be tightly bound with a band.
Accordingly, the outer wall of the core case 132 is provided with grooves 134 in the circumferential direction, wherein the groove 134 of one connection terminal 1 is butted against the groove 134 of the other connection terminal 1.
The groove 134 may be used to install a tie.
Still alternatively, referring to fig. 2, the core housings 132 of the two connection terminals 1 may be connected by means of a slider 15. Each connection terminal 1 further includes a slider 15, the slider 15 is slidably disposed in the groove 134, and the slider 15 is provided with a mounting hole 151.
Accordingly, the groove 134 is radially provided with a screw hole 135 to be fitted with the mounting hole 151.
The slider 15 may be a band-like structure with two sides that engage and slide against the side walls of the recess 134. When the core sleeve 132 is a semi-cylindrical structure, the slide fastener 15 and the groove 134 are semi-circular ring structures.
The mounting holes 151 and the threaded holes 135 are matched, the number of the mounting holes can be multiple, and the mounting holes can be uniformly arranged on the slide fastener 15 and the groove 134. The mounting holes 151 and the screw holes 135 are used for mounting fastening screws.
After the two connection terminals 1 are connected, the grooves 134 of the two connection terminals 1 are butted to form a circular track, the sliders 15 of the two connection terminals 1 are respectively slid, so that the two sliders 15 are respectively positioned at the butted positions of the two grooves 134, the mounting holes 151 on the sliders 15 are aligned with the threaded holes 135 on the grooves 134, fastening screws are mounted in the mounting holes 151, and the sliders 15 are fixed on the grooves 134 through the fastening screws.
The groove 134 and the slide fastener 15 form a fixing structure of the two connecting terminals 1, and the two connecting terminals 1 are fixed by the fixing structure, so that the fixing mode is simple, effective and convenient; meanwhile, the above-described fixing structure is the same for each of the connection terminals 1, ensuring that each of the connection terminals 1 has the same structure.
Fig. 3 and 4 show the connection terminal after the slider is removed.
Compared with the cable connecting device provided by the related art, the cable connecting device provided by the embodiment is simple to operate and reliable in connection when in use, and can reduce electromagnetic laying at the cable connecting position and reliably shield and connect two cables.
