Reference is made to FIGS. 1 to 5, FIG. 1 is a schematic diagram of a cable assembly of the present disclosure, FIG. 2 and FIG. 3 are respectively exploded schematic views of different components of the cable assembly of the present disclosure, FIG. 4 is a schematic cross-sectional view of a second outer metal member of a cable connection component of the cable assembly of the present disclosure, and FIG. 5 is a schematic cross-sectional view of the cable assembly of the present disclosure.

A cable assembly A of the present disclosure includes a cable connecting component A1 and a cable A2. The cable connection component A1 is used to fix an end of the cable A2. The cable connection component A1 includes a first outer metal member 1, a second outer metal member 2 and a holding component 3. The first outer metal member 1 has a guiding structure 11 at an end thereof, two connection conductors 12 are disposed in the first outer metal member 1, and two insulating structures 13 are disposed between the two connection conductors 12 and the first outer metal member 1, respectively. Each of the connecting conductors 12 has a clamping structure 121, and the clamping structure 121 is used for clamping an end of an inner conductor A221 of each of the core wires A22 included in the cable A2.

The second outer metal member 2 has an end detachably fixed to the guiding structure 11 of the first outer metal member 1. In practical applications, the first outer metal member 1 and the second outer metal member 2 can have corresponding thread structures, respectively, and the first outer metal member 1 and the second outer metal member 2 can be interlocked through the corresponding thread structures.

The holding component 3 is disposed between the first outer metal member 1 and the second outer metal member 2, and the holding component 3 is held by the first outer metal member 1 and the second outer metal member 2. The holding component 3 has a guide structure 31 at an end thereof for engaging with the guide structure 11 of the first outer metal member 1. In practical applications, the guide structure 11 of the first outer metal member 1 can be a rectangular groove, and the guide structure 31 of the holding component 3 can correspondingly be a rectangular structure. When the guide structure 11 of the first outer metal member 1 and the guiding structure 31 of the holding component 3 are engaged with each other, the holding component 3 will be unable to be rotated relative to the first outer metal member 1, thereby effectively reducing damages to the core wires A22 included in the cable A2 caused by relative rotation of the first outer metal member 1 and the holding component 3. In addition, through the design of the guide structures 11 and 31, technical personnel can also be assisted in assembling the first outer metal member 1 and the holding component 3 more conveniently.

The holding component 3 includes two inner metal members 32 and a fixing member 33, and the two inner metal members 32 are fixed to each other by the fixing member 33. For example, each inner metal member 32 can include a through hole 321, and the fixing member 33 can be a screw, a portion of the fixing member 33 passes through one of the through holes 321, and an end of the fixing member 33 is locked in another through hole 321 having an inner wall with threads. By having the holding component 3 include the two inner metal members 32 and the fixing member 33 so as to hold the end of the cable A2 in place, a size of each of the members during the production process can be more accurately controlled, and each of the members with such design can be easily assembled by technical personnel.

In practical applications, an end of each inner metal member 32 can have a protruding structure 322, therefore, when the two inner metal members 32 are fixed to each other by the fixing member 33, the two protruding structures 322 will together form the guiding structure 31. In special applications, the guide structure 31 of the holding component 3 can also be formed in only one inner metal member 32.

A wide side surface 32A of each inner metal member 32 is concavely formed with a wire slot 323, the wire slot 323 includes an end section 3231 and two branch sections 3232, an end of each of the two branch sections 3232 is connected to the end section 3231, the other end of each of the two branch sections 3232 is disposed adjacent to the end of the inner metal member 32 where the guide structure 31 is formed, the other ends of the two branch sections 3232 are spaced apart from each other, and the wire slots 323, as a whole, are presented as a shape similar to that of the letter “Y.” Through the Y-shaped design of the wire slot 323 as a whole, the clamped cable A2 can be effectively prevented from moving back and forth relative to the inner metal member 32.

Specifically, the protruding structure 322 of each inner metal member 32 can be located between the two branch sections 3232 correspondingly. In practical applications, a size of each of the wire slots 323 can be slightly smaller than a size of the core wire A22, and each of the core wires A22 can be engaged in the wire slot 323, such that it is convenient for the technical personnel to fix the two core wires A22 and the holding component 3 to each other.

Sides of the two inner metal members 32 have the wire slots 323 formed therewith arranged to face each other, portions of the end sections 3231 of the two inner metal members 32 are used to jointly hold a portion of the cable A2 in place, the branch sections 3232 of the two inner metal members 32 jointly hold the insulator A222 of the core wire A22 in place, and the inner conductor A221 of each core wire A22 is exposed at the end of the holding component 3 where the protruding structure 322 is formed, and is connected with the two connection conductors 12 of the two connection conductors 12.

It should be noted that, through the design of each wire slot 323 with the end section 3231, in a process of fixing the cable A2 and the holding component 3 to each other, the technical personnel can first have a portion of the cable A2 be engaged with the end section 3231, and then have the two core wires A22 be fixed to the two branch sections 3232, respectively, such that an assembly of the cable A2 and the holding component 3 can be completed in a relatively convenient and easy way, especially in a case where a size of the holding component 3 is relatively small.

In a preferred embodiment, a side of one of the inner metal members 32 that has the wire slot 323 formed therewith has two positioning structures 324A, a side of another one of the inner metal members 32 that has the wire slot 323 formed therewith has two positioning structures 324B, the two positioning structures 324A can be engaged with the two positioning structures 324B, and the two inner metal members 32 can be fixed to each other by the four positioning structures 324A and 324B. In practical applications, at least one of the positioning structures 324A of one of the inner metal members 32 is, for example, a post structure, and at least one of the positioning structures 324B of another inner metal member 32 can correspondingly be a groove structure. Through the design of the positioning structures 324A, 324B, the technical personnel can first fix the two inner metal members 32 to each other through the positioning structures 324A and 324B, and then use the fixing member 33 to lock the two inner metal members 32 to each other.

As shown in FIG. 2, the end of the first outer metal member that has the guide structure formed therewith further has a limiting groove 14, the holding component 3 has a limiting portion 34 for engaging with the limiting groove 14, and accordingly restricts a range of motion in which the holding component 3 and the first outer metal member 1 can rotate relative to each other. Specifically, the limiting groove 14 can be, for example, a rectangular groove, and the limiting portion 34 can correspondingly be a rectangular structure. Through the design of the limiting groove 14, the first outer metal member 1 and the holding component 3 are basically unable to be rotated relative to each other, so that the core wires A22 can be prevented from being twisted and broken due to relative rotation of the first outer metal member 1 and the holding assembly 3.

As shown in FIGS. 2 and 5, in practical applications, a length of the guide structure 31 of the holding component 3 in an axial direction (Y-axis direction of coordinates shown in FIG. 5) can be made to be larger than a length of the core wire A22 that is exposed to the holding component 3 in the axial direction. Therefore, in a process of connecting the inner conductors A221 of the two core wires A22 and the connection conductor 12 of the first outer metal member 1 to each other performed by the technical personnel, before the inner conductor A221 of the two-core wire A22 is connected to the connection conductor 12 of the first outer metal member 1, the guide structure 31 of the holding assembly 3 will be engaged with the guide structure 11 of the first outer metal member 1, thereby ensuring that the inner conductor A221 of each core wire A22 can be correctly connected to the clamping structure 121 of the connecting conductor 12 of the first outer metal member 1.

As shown in FIGS. 3 and 4, the second outer metal member 2 has an end that is recessed to form an accommodating groove 21, the second outer metal member 2 has a wire hole 22 at another end thereof, the wire hole 22 penetrates the second outer metal member 2, and the wire hole 22 communicates with the accommodating groove 21. Another end of the holding component 3, which is opposite to the end with the two core wires A22 exposed, is correspondingly snap-fitted into and disposed in the accommodating groove 21 of the second outer metal member 2, and the holding component 3, as a whole, is disposed in the first outer metal member 1 and the second outer metal member 2. Preferably, a size of the limiting portion 34 of the holding component 3 is larger than an inner diameter of the accommodating groove 21, and when the holding component 3 is accommodated in the accommodating groove 21, the limiting portion 34 is the end that is correspondingly exposed from the accommodating groove 21. In this way, it is convenient for technical personnel to assemble the first outer metal member 1, the second outer metal member 2 and the holding assembly 3.

As shown in FIGS. 6 and 7, the cable A2 includes an outer insulator A21, two core wires A22, an aluminum foil outer conductor A23 and two steel wire outer conductors A24. The two core wires A22 are wrapped by the outer insulator A21, each of the core wires A22 includes an inner conductor A221 and an insulator A222, and the inner conductor A221 is wrapped by the insulator A222. The aluminum foil outer conductor A23 wraps the insulators A222 of the two core wires A22, the aluminum foil outer conductor A23 of the cable A2 is held by the end sections 3231 of the two inner metal members 32, and the insulator A222 of each core wire A22 is together held by one of the branch sections 3232 of the two inner metal members 32. In this way, the cable A2 being moved back and forth relative to the cable connection assembly A1 by external forces can be effectively avoided. Each of the steel wire outer conductors A24 together with the aluminum foil outer conductor A23 are held by the end sections 3231 of the two inner metal members 32, such that an overall anti-interference capability of the cable A2 can be further improved, and loss of the cable A2 during signal transmissions can be further reduced. In practical applications, the cable A2 can be, for example, a twinaxial cable, but the present disclosure is not limited thereto. Through the design of the holding component 3 including two inner metal members 32, and each of the inner metal members 32 using the end section 3231 to jointly hold the aluminum foil outer conductor A23 and steel wire outer conductor A24 of the cable A2 in place, the holding component 3 can tightly hold the cable A2 in place.

It should be noted that the above-mentioned cable connection component A1 can also be manufactured, implemented and sold independently, and is not limited to being manufactured, implemented and sold only together with the cable assembly A.

In conclusion, in the cable assembly and cable connection component provided by the present disclosure, through the above design of the first outer metal member, the second outer metal member, the two inner metal members included in the holding member, and the wire slot of each of the inner metal members, such that the cable assembly and the cable connection component can be provided with better anti-interference capabilities than the existing cables.
