DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0044] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0045] The embodiments of the present application provide a cable clamp and a cable testing device. Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 A module structure block diagram of a cable clamp provided in an embodiment of the present application, Figure 2 A schematic diagram of a scenario in which a cable clamp clamps a target cable according to an embodiment of the present application. Figure 3 A schematic diagram of the exploded structure of a connecting mechanism and a first clamping mechanism in a cable clamp provided in an embodiment of the present application.

[0047] like Figures 1 to 3 As shown, the embodiment of the present application provides a cable clamp 100, which is used to fix a target cable 300 to be tested, and connect the target cable 300 to a preset external device to assist the external device in testing the communication parameters of the target cable 300, wherein the cable clamp 100 at least includes a connecting mechanism 110 and a first clamping mechanism 120. The various parts of the cable clamp 100 are described in detail below.

[0048] Specifically, the connection mechanism 110 includes a patch cord 111 and a shell component 112 covering the patch cord 111, the shell component 112 forms a plug opening 130, and the patch cord 111 is used to connect the target cable 300 plugged into the plug opening 130 with a preset external device. Further explanation, the patch cord 111 has a first end and a second end opposite to each other, wherein the first end of the target cable 300 is opposite to the plug opening 130 and is used to connect with the target cable 300 plugged into the plug opening 130, and the second end of the target cable 300 is used to connect with the external device, thereby connecting the target cable 300 with the external device.

[0049] Specifically, the first clamping mechanism 120 includes a guide groove component 121 and a clamping component 122. The guide groove component 121 forms a tension guide groove 123 having a first direction and a second direction. The clamping component 122 clamps one end of the housing component 112 close to the plug opening 130, and the clamping component 122 and the tension guide groove 123 are slidably matched. When the target cable 300 to be detected is plugged into the plug opening 130, if the clamping component 122 slides in the tension guide groove 123 in the first direction, the clamping component 122 loosens the clamping of the housing component 112, so that the connection between the target cable 300 and the plug opening 130 is loosened; if the clamping component 122 slides in the tension guide groove 123 in the second direction, the clamping component 122 tightens the clamping of the housing component 112, so that the connection between the target cable 300 and the plug opening 130 is tightened.

[0050] 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 tension guide groove 123 toward the first direction, the clamping assembly 122 loosens the clamping of the outer shell assembly 112, and the diameter of the plug-in opening 130 increases. When the clamping assembly 122 slides in the tension guide groove 123 toward the second direction, the clamping assembly 122 tightens the clamping of the outer shell assembly 112, and the diameter of the plug-in opening 130 decreases.

[0051] 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) of the target cable 300.

[0052] When the cable clamp 100 is needed 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, and then the clamping component 122 can be operated to slide in the second direction to tighten the clamping of the clamping component 122 on the outer shell component 112 and reduce the diameter of the plug-in opening 130, and the clamping of the target cable 300 by the cable clamp 100 is also tightened.

[0053] By setting up the 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.

[0054] like Figures 1 to 3 As shown, in some embodiments, the tension 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;

[0055] 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 .

[0056] 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 groove portion 1231 along the first direction or the second direction, and when the second clamping member 1222 is assembled in the second groove portion 1232, the second clamping member 1222 can slide in the second groove portion 1232 along the first direction or the second direction.

[0057] Specifically, the first clamping member 1221 is connected to the second clamping member 1222 and is used to cooperate with the clamping housing assembly 112. It should be understood that since the spacing between the first groove portion 1231 and the second groove portion 1232 in the first direction is greater than the spacing 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 is reduced, and the clamping of the housing assembly 112 by the clamping assembly 122 is loosened; 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 is increased, and the clamping of the housing assembly 112 by the clamping assembly 122 is tightened.

[0058] like Figure 3 As shown, 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.

[0059] 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 .

[0060] 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 can 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, thereby optimizing the operating experience.

[0061] like Figure 3As shown, 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 push rod opening 1213 and out of the first clamping plate 1211.

[0062] Specifically, the first clamping plate 1211 is connected to the second clamping plate 1212, and at least one of the first clamping plate 1211 and the second clamping plate 1212 is used to form the tension guide groove 123, wherein the first clamping plate 1211 also forms a push rod opening 1213 connected to the tension guide groove 123, thereby, when the clamping assembly 122 is installed and adapted to the tension guide groove 123, the push rod assembly 124 passes through the push rod opening 1213 and passes through the first clamping plate 1211, 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.

[0063] See also Figure 4 , Figure 4 A schematic structural diagram of a connecting mechanism and a clamping assembly in a cable clamp provided in an embodiment of the present application.

[0064] like Figures 1 to 4 As shown, 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 ;

[0065] The patch cord 111 includes a first cord 1111 at least partially received in the first chamber 1123 and a second cord 1112 at least partially received in the second chamber 1124 .

[0066] Specifically, the first shell 1121 is formed with a first chamber 1123, the second shell 1122 is formed with a second chamber 1124, and the first chamber 1123 and the second chamber 1124 are both connected to the plug opening 130, and the patch cord 111 includes a first cord 1111 and a second cord 1112, wherein the first cord 1111 is at least partially accommodated in the first chamber 1123, and the second cord 1112 is at least partially accommodated in the second chamber 1124. It should be noted that one end of the first cord 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, and the same is true for the second cord 1112.

[0067] like Figures 1 to 4As shown, 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.

[0068] 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.

[0069] like Figures 1 to 4 As shown, in some embodiments, the first housing 1121 includes a first front end portion 1125 connected to the second housing 1122, the second housing 1122 includes a second front end portion 1126 tightly connected to the first front end portion 1125, and 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;

[0070] 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 .

[0071] 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 cooperate 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.

[0072] like Figure 4 As shown, 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 .

[0073] It should be noted that, in some embodiments, part of the first core 1111 and / or the second core 1112 may be accommodated in a common cavity, and in other embodiments, the first core 1111 may be accommodated only in the first cavity 1123 , and the second core 1112 may be accommodated only in the second cavity 1124 .

[0074] 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.

[0075] like Figure 4 As shown, 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 arranged on the peripheral side of the housing assembly 112;

[0076] When the clamping assembly 122 slides in the second direction in the tension guide groove 123, the distance between the two adjacent support portions 1223 is reduced under the pressure exerted by the inner wall of the tension guide groove 123 on the housing assembly 112, and the diameter of the plug-in opening 130 is reduced accordingly, and the clamping of the housing assembly 112 by the clamping assembly 122 is tightened. Conversely, when the clamping assembly 122 slides in the first direction in the tension guide groove 123, the pressure exerted by the inner wall of the tension guide groove 123 on the housing assembly 112 is reduced, and the distance between the two adjacent support portions 1223 is restored, and the diameter of the plug-in opening 130 is increased accordingly, and the clamping of the housing assembly 112 by the clamping assembly 122 is loosened.

[0077] It should be understood that providing the support portions 1223 arranged at intervals on the peripheral side of the housing component 112 is beneficial to the elastic compression and elastic recovery of the housing component 112 , and improves the adjustability of the diameter of the plug-in opening 130 .

[0078] See also Figure 5 , Figure 5 A schematic diagram of the exploded structure of a cable clamp provided in an embodiment of the present application.

[0079] like Figure 1-5 As shown, 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-in opening 130, and is formed with a clamping opening 150 opposite to the plug-in 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.

[0080] 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 match target cables 300 of different sizes.

[0081] 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.

[0082] Specifically, a clamping slot 143 for adapting the target cable 300 is formed between the first grounding spring piece 141 and the second grounding spring piece 142.
