DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0044] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, combined, or partially merged, so the actual execution order may vary depending on the actual situation.

[0045] It should be understood that the terms used in this disclosure are only for the purpose of describing particular embodiments and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0046] The present disclosure provides a cable clamp and a cable testing device. The following describes some embodiments of the present disclosure in detail with reference to the accompanying drawings. The following embodiments and features thereof may be combined with one another unless they conflict.

[0047] Please refer to Figures 1, 2 and 3. Figure 1 is a module structure block diagram of a cable clamp provided in an embodiment of the present disclosure. Figure 2 is a scene schematic diagram of a cable clamp clamping a target cable provided in an embodiment of the present disclosure. Figure 3 is an exploded structure schematic diagram of a connecting mechanism and a first clamping mechanism in a cable clamp provided in an embodiment of the present disclosure.

[0048] As shown in Figures 1 to 3, an embodiment of the present disclosure provides a cable clamp 100 for securing a target cable 300 to be tested and connecting the target cable 300 to a predetermined external device to assist the external device in testing the communication parameters of the target cable 300. The cable clamp 100 includes at least a connecting mechanism 110 and a first clamping mechanism 120. The various components of the cable clamp 100 are described in detail below.

[0049] Specifically, the connection mechanism 110 includes a patch cord 111 and a housing assembly 112 covering the patch cord 111. The housing assembly 112 defines a plug opening 130. The patch cord 111 is used to connect a target cable 300 plugged into the plug opening 130 to a predetermined external device. Specifically, the patch cord 111 has a first end and a second end opposite each other. The first end of the target cable 300 is opposite the plug opening 130 and is used to connect to the target cable 300 plugged into the plug opening 130. The second end of the target cable 300 is used to connect to the external device, thereby connecting the target cable 300 to the external device.

[0050] Specifically, the first clamping mechanism 120 includes a guide groove assembly 121 and a clamping assembly 122. The guide groove assembly 121 forms a tension guide groove 123 having a first direction and a second direction. The clamping assembly 122 clamps one end of the housing assembly 112 near the plug opening 130, and the clamping assembly 122 and the tension guide groove 123 slide in engagement. When the target cable 300 to be inspected is plugged into the plug opening 130, if the clamping assembly 122 slides in the tension guide groove 123 in the first direction, the clamping assembly 122 loosens its grip on the housing assembly 112, thereby loosening the connection between the target cable 300 and the plug opening 130. If the clamping assembly 122 slides in the tension guide groove 123 in the second direction, the clamping assembly 122 tightens its grip on the housing assembly 112, thereby tightening the connection between the target cable 300 and the plug opening 130.

[0051] Furthermore, the first direction is opposite to the second direction, and the user can operate the clamping assembly 122 to slide on the guide groove assembly 121. When the clamping assembly 122 slides in the first direction in the elastic guide groove 123, the clamping of the clamping assembly 122 on the outer shell assembly 112 is loosened, and the diameter of the plug-in opening 130 increases. When the clamping assembly 122 slides in the second direction in the elastic guide groove 123, the clamping of the clamping assembly 122 on the outer shell assembly 112 is tightened, and the diameter of the plug-in opening 130 is reduced.

[0052] For example, the external device is a test device 200 including a network analyzer. When the target cable 300 is connected to the external device through the cable clamp 100, the external device can detect and obtain the communication parameters of the target cable 300, such as the S parameters (Scatter, scattering parameters) of the target cable 300.

[0053] When the cable clamp 100 needs to be used to fix the target cable 300, the clamping component 122 can be operated to slide in the first direction to increase the diameter of the plug-in opening 130, and then the target cable 300 can be inserted into the plug-in opening 130 and connected to the adapter core 111. The clamping component 122 is then operated to slide in the second direction to tighten the clamping component 122 on the housing component 112 and reduce the diameter of the plug-in opening 130. The cable clamp 100 also tightens its clamping of the target cable 300.

[0054] By setting up a clamping mechanism, the user can directly control the clamping assembly 122 to move in the first direction or the second direction to adjust the clamping tightness of the plug-in opening 130, which not only improves the adaptability of the cable clamp 100 to cables of different diameters, but also improves the fixing effect and clamping performance of the cable clamp 100 on the cables.

[0055] As shown in FIG1 to FIG3, in some embodiments, the elastic guide groove 123 includes a first groove portion 1231 and a second groove portion 1232 arranged at an angle, and the distance between the first groove portion 1231 and the second groove portion 1232 in the first direction is greater than the distance between the first groove portion 1231 and the second groove portion 1232 in the second direction;

[0056] The clamping assembly 122 includes a first clamping member 1221 and a second clamping member 1222 for cooperating with the first clamping member 1221 to clamp the housing assembly 112 . The first clamping member 1221 slidably cooperates with the first groove 1231 , and the second clamping member 1222 slidably cooperates with the second groove 1232 .

[0057] Specifically, when the first clamping member 1221 is assembled in the first groove portion 1231, the first clamping member 1221 can slide in the first direction or the second direction in the first groove portion 1231, and when the second clamping member 1222 is assembled in the second groove portion 1232, the second clamping member 1222 can slide in the first direction or the second direction in the second groove portion 1232.

[0058] Specifically, the first clamping member 1221 and the second clamping member 1222 are connected and are used to cooperate in clamping the housing assembly 112. It should be understood that because the distance between the first groove portion 1231 and the second groove portion 1232 in the first direction is greater than the distance between the first groove portion 1231 and the second groove portion 1232 in the second direction, when the first clamping member 1221 and the second clamping member 1222 both slide in the corresponding guide groove in the first direction, the pressure exerted by the groove wall of the corresponding guide groove on the first clamping member 1221 and the second clamping member 1222 decreases, and the clamping assembly 122 loosens its grip on the housing assembly 112; when the first clamping member 1221 and the second clamping member 1222 both slide in the corresponding guide groove in the second direction, the pressure exerted by the groove wall of the corresponding guide groove on the first clamping member 1221 and the second clamping member 1222 increases, and the clamping assembly 122 tightens its grip on the housing assembly 112.

[0059] As shown in Figure 3, in some embodiments, the first clamping mechanism 120 also includes a push rod assembly 124, which is connected to the first clamping member 1221 and the second clamping member 1222, and is used to drive the first clamping member 1221 to slide in the first groove 1231 and drive the second clamping member 1222 to slide in the second groove 1232.

[0060] Specifically, the push rod assembly 124 can be directly connected to both the first clamping member 1221 and the second clamping member 1222, or can be connected to one of the first clamping member 1221 and the second clamping member 1222, and the first clamping member 1221 is connected to the second clamping member 1222.

[0061] It should be understood that when the clamping assembly 122 is assembled in the tension guide groove 123, the user can directly operate the push rod assembly 124 to move in the first direction, so that the first clamping member 1221 and the second clamping member 1222 are driven by the push rod assembly 124 to move in the first direction at the same time, or directly operate the push rod assembly 124 to move in the second direction, so that the first clamping member 1221 and the second clamping member 1222 are driven by the push rod assembly 124 to move in the second direction at the same time. Therefore, the setting of the push rod assembly 124 greatly facilitates the user's control of the clamping assembly 122 to adjust the tightness of the plug-in opening 130, and optimizes the operating experience.

[0062] As shown in Figure 3, in some embodiments, the guide groove assembly 121 includes a first clamping plate 1211 and a second clamping plate 1212, and the first clamping plate 1211 and the second clamping plate 1212 are connected and cooperate to form an elastic guide groove 123, and the first clamping plate 1211 also forms a push rod opening 1213 connected to the elastic guide groove 123; wherein, when the clamping assembly 122 is installed and adapted to the elastic guide groove 123, the push rod assembly 124 passes through the first clamping plate 1211 through the push rod opening 1213.

[0063] Specifically, the first splint 1211 is connected to the second splint 1212, and at least one of the first splint 1211 and the second splint 1212 is used to form the tension guide groove 123, wherein the first splint 1211 also forms a push rod opening 1213 connected to the tension guide groove 123. Therefore, when the clamping assembly 122 is installed and adapted to the tension guide groove 123, the push rod assembly 124 passes through the first splint 1211 through the push rod opening 1213, and the user can directly operate the push rod assembly 124, which greatly facilitates the user's control of the clamping assembly 122 to adjust the tightness of the plug-in opening 130, thereby optimizing the operating experience.

[0064] Please refer to FIG4 , which is a structural diagram of a connecting mechanism and a clamping assembly in a cable clamp provided by an embodiment of the present disclosure.

[0065] As shown in FIG. 1 to FIG. 4 , in some embodiments, the housing assembly 112 includes a first shell 1121 and a second shell 1122 . The first shell 1121 forms a first chamber 1123 communicating with the plug opening 130 , and the second shell 1122 forms a second chamber 1124 communicating with the plug opening 130 .

[0066] The patch cord 111 includes a first cord 1111 at least partially housed in the first chamber 1123 and a second cord 1112 at least partially housed in the second chamber 1124 .

[0067] Specifically, the first housing 1121 is formed with a first chamber 1123, and the second housing 1122 is formed with a second chamber 1124. Both the first chamber 1123 and the second chamber 1124 are in communication with the plug opening 130. The patch cable 111 includes a first core 1111 and a second core 1112. The first core 1111 is at least partially housed in the first chamber 1123, and the second core 1112 is at least partially housed in the second chamber 1124. It should be noted that one end of the first core 1111 is used to connect to the target cable 300 plugged into the plug opening 130, and the other end is used to connect to an external device. The same applies to the second core 1112.

[0068] As shown in Figures 1 to 4, in some embodiments, the target cable 300 includes at least two target cores 301. When the target cable 300 is plugged into the plug opening 130 and the two target cores 301 are both adapted to the plug opening 130, the two target cores 301 are respectively connected to the first core 1111 and the second core 1112 in the adapter core 111.

[0069] It should be noted that when the two target cores 301 are respectively connected to the first core 1111 and the second core 1112 in the adapter core 111, the first core 1111 and the second core 1112 can connect the two target cores 301 to two different external devices respectively, or can connect the first core 1111 and the second core 1112 to the same external device.

[0070] As shown in FIG1 to FIG4 , in some embodiments, the first housing 1121 includes a first front end portion 1125 connected to the second housing 1122, and the second housing 1122 includes a second front end portion 1126 tightly connected to the first front end portion 1125. The first front end portion 1125 and the second front end portion 1126 cooperate to enclose the first wire core 1111 and the second wire core 1112.

[0071] The cross-sectional areas of the first front end portion 1125 and the first front end portion 1125 are greater than the cross-sectional areas of the first wire core 1111 and the second wire core 1112 .

[0072] Specifically, the first front end portion 1125 is arranged on a side of the first shell 1121 close to the plug-in opening 130, and the second front end portion 1126 is arranged on a side of the second shell 1122 close to the plug-in opening 130. The first front end portion 1125 and the second front end portion 1126 are tightly connected to form a common cavity, and the common cavity is connected to the plug-in opening 130. When the target cable 300 is plugged into the plug-in opening 130, the target cable 300 is connected to the adapter core 111 through the plug-in opening 130 and the common cavity.

[0073] As shown in FIG. 4 , illustratively, the first front end portion 1125 and the second front end portion 1126 may be obtained by cutting off sector-shaped portions from the cylindrical first shell 1121 and the second shell 1122 .

[0074] It should be noted that, in some embodiments, part of the first core 1111 and / or the second core 1112 will be accommodated in the common cavity. In other embodiments, the first core 1111 is only accommodated in the first cavity 1123, and the second core 1112 is only accommodated in the second cavity 1124.

[0075] It should also be noted that the cross-sectional area of ​​the first front end portion 1125 and the first front end portion 1125 is larger than the cross-sectional area of ​​the first core 1111 and the second core 1112 to ensure the closed wrapping of the adapter core 111 and the plugged target cable 300, and is also suitable for matching target cables 300 of different sizes.

[0076] As shown in FIG4 , in some embodiments, the first clamping member 1221 and / or the second clamping member 1222 includes at least two supporting portions 1223 , and the at least two supporting portions 1223 are spaced apart and disposed on the circumference of the housing assembly 112 ;

[0077] When the clamping assembly 122 slides in the second direction within the tensioning guide groove 123, the pressure exerted by the inner wall of the tensioning guide groove 123 on the housing assembly 112 reduces the distance between the two adjacent support portions 1223, and the diameter of the plug-in opening 130 decreases accordingly, tightening the clamping assembly 122 on the housing assembly 112. Conversely, when the clamping assembly 122 slides in the first direction within the tensioning guide groove 123, the pressure exerted by the inner wall of the tensioning guide groove 123 on the housing assembly 112 decreases, restoring the distance between the two adjacent support portions 1223, and increasing the diameter of the plug-in opening 130, loosening the clamping assembly 122 on the housing assembly 112.

[0078] It should be understood that providing the support portions 1223 arranged at intervals on the circumference of the housing assembly 112 is beneficial to the elastic compression and elastic recovery of the housing assembly 112 , thereby improving the adjustability of the diameter of the plug opening 130 .

[0079] Please refer to FIG5 , which is a schematic diagram of an exploded structure of a cable clamp provided in an embodiment of the present disclosure.

[0080] As shown in Figures 1-5, in some embodiments, the cable clamp 100 also includes a second clamping mechanism 140, which is arranged in the direction of the connecting mechanism 110 toward the plug opening 130 and is formed with a clamping opening 150 opposite to the plug opening 130, wherein the second clamping mechanism 140 is also used to adjust the size of the clamping opening 150 to clamp the target cable 300.

[0081] Specifically, when the size of the clamping opening 150 is reduced, the second clamping mechanism 140 tightens the clamping of the target cable 300, and when the size of the clamping opening 150 is increased, the second clamping mechanism 140 tightens the clamping of the target cable 300. In this embodiment, the clamping opening 150 is adjustable to accommodate target cables 300 of different sizes.

[0082] In some embodiments, the second clamping mechanism 140 includes a first grounding spring clip 141, a second grounding spring clip 142, and a clamping drive component. The first grounding spring clip 141 and the second grounding spring clip 142 are used to cooperate in clamping the target cable 300. The clamping drive component is connected to at least one of the first grounding spring clip 141 and the second grounding spring clip 142, and is used to drive the first grounding spring clip 141 and the second grounding spring clip 142 to move toward or away from each other.

[0083] Specifically, a clamping slot 143 for adapting to the target cable 300 is formed between the first grounding spring piece 141 and the second grounding spring piece 142. The clamping drive member drives the first grounding spring piece 141 and the second grounding spring piece 142 to move toward or away from each other to adjust the size of the clamping opening 150, so that the cable clamp 100 is suitable for matching target cables 300 of different sizes.

[0084] It should be noted that the first grounding elastic piece 141 and the second grounding elastic piece 142 are grounded to ensure the integrity of signal transmission in the target cable 300 so that external equipment can accurately test the performance of the target cable 300 .

[0085] Exemplarily, the clamping drive member includes a bolt member, the first grounding spring piece 141 is formed with a first bolt hole 1411 that cooperates with the bolt member, the second grounding spring piece 142 is formed with a second bolt hole 1421 that cooperates with the bolt member, and the first bolt hole 1411 and the second bolt hole 1421 are arranged opposite to each other, then the user can rotate the clamping drive member to drive the first grounding spring piece 141 and the second grounding spring piece 142 to move toward or away from each other.

[0086] Please refer to FIG. 6 , which is a schematic structural diagram of a second clamping mechanism in a cable clamp provided in an embodiment of the present disclosure.

[0087] As shown in FIG. 6 , in some embodiments, a clamping notch 143 for adapting to the target cable 300 is further formed between the first grounding elastic piece 141 and the second grounding elastic piece 142 .

[0088] Specifically, the clamping notch 143 is used to adapt to the target cable 300 and limit its position, thereby improving the relative fixation between the target cable 300 and the cable clamp 100 and enhancing the stability of the connection between the target cable 300 and the external device.
