DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0021] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0022] In one embodiment, please refer to Figure 1-3 As shown, the present invention provides a cable clamp 101, which includes a clamping bracket 8, a positioning structure 14 connected to the clamping bracket 8, and a cam shaft 13 passing through the clamping bracket 8 and a dial wheel 7 connected at both ends thereof, and the dial wheel 7 rotates forward or reversely when a force is applied. The positioning structure 14 has a positioning hole 6 for receiving a first positioning pin 16. The clamping bracket 8 is a structure of a pair of support plates and forms an integral body with the general structure of the cable clamp 101. The support plate has holes that allow the cam shaft 13 to pass through the clamping bracket 8. The dial wheel 7 connected at both ends of the cam shaft 13 rotates forward or reversely when a force is applied. For example, a positive force is applied to the dial wheel 7 to cause the dial wheel 7 to rotate forward, and conversely, a reverse force is applied to the dial wheel 7 to cause the dial wheel 7 to rotate reversely.

[0023] The cable clamp 101 further includes a pair of movable parts 5 supported by the clamping bracket 8, the pair of movable parts 5 are pivotally connected to each other, and each movable part 5 includes a first end 2 located on the side of the cam shaft 13 and a second end 3 opposite to the first end 2. The first end 2 abuts against the cam shaft 13 or not when the thumbwheel 7 rotates forward or reversely. When the first end 2 abuts against the cam shaft 13, the pair of movable parts 5 can be pushed to pivot relative to each other so that the pair of second ends 3 clamp the cable terminal. The pair of second ends 3 are in a contoured structure matching the size of the cable terminal 10 and are used to clamp the cable terminal 10 when the first end 2 abuts against the cam shaft 13, such as Figure 2 The second end 3 is shown as clamping the cable terminal 10. Figure 3As shown, the thumbwheels 7 connected to the two ends of the camshaft 13 share a common shaft, and a cam 12 is provided in the middle of the camshaft 13. The cam 12 can push the first ends 2 located on both sides thereof away from each other, and the cam 12 realizes the clamping and locking function of the cable terminal 10. For example, when the thumbwheel 7 is rotated forward, the cam 12 on the same shaft also rotates, so that the first end 2 abuts against the cam 12, and a pair of second ends 3 are connected by a spring, and the spring is used to bias the pair of second ends 3 away from each other and is in a tightened state when the first end 2 abuts against the cam 12, so that the pair of second ends 3 clamp the cable terminal 10. In other words, the pair of second ends 3 are supported by the spring, and the second ends 3 are in an open state in the natural state. The spring is in a tightened state when the first end 2 abuts against the cam 12, so as to realize the locking function of the second ends 3. Conversely, when the thumbwheel 7 is rotated in the reverse direction, the cam 12 on the same shaft also rotates, the first end 2 does not abut against the cam 12, and the spring is used to push the second ends 3 away from each other, so as to realize the loosening function of the second ends 3. The cam 12 of the camshaft 13 of the cable clamp 101 is conducive to ensuring the clamping function of the cable terminal 10. By rotating the dial wheel 7, the cam 12 drives the clamping structure, thereby achieving the second end 3 clamping the cable terminal 10. Figure 2 The state in which the second end 3 locks the cable terminal 10 is shown. At the same time, the pair of movable parts 5 are provided with corresponding first mounting holes 9, and the pair of movable parts 5 are mounted on both sides of the clamping bracket 8 by means of the mounting shaft 11 (i.e., the pin shaft) passing through the first mounting hole 9, and form a four-sided support structure with the clamping bracket 8. Since the structure of the pair of second ends 3 is a profiling structure designed according to the shape structure of the cable terminal 10, that is, the structure of the second end 3 can be flexibly changed according to the shape and size of the specific cable terminal 10. When the cable terminal 10 is clamped by the pair of second ends 3, the cable terminal 10 can be clamped stably, and problems such as skewing and loosening can be avoided, so as to improve the installation accuracy of the subsequent cable terminal 10. At the same time, the profiling structure of the second end 3 can ensure that the second end 3 is closely fitted to the cable terminal 10, ensure that the force of clamping the cable terminal 10 is uniform, and ensure stable clamping and horizontal installation when clamping the cable terminal 10.

[0024] The cable clamp 101 also includes a connection end 1 located above the cam shaft 13 and connected to the clamping bracket 8. The connection end 1 has an interface 4 that can be connected to a mobile device, and the interface 4 is used to connect to the mobile device to move the cable clamp 101 to a target position. Optionally, the end of the mobile device is inserted into the interface 4 of the connection end 1 to connect the cable clamp 101 to the mobile device, and the cable clamp 101 is moved to a designated position by the movement of the mobile device to ensure that during the installation of the cable terminal 10, the cable clamp 101 clamps the cable terminal 10 to the accurate position before releasing the cable terminal 10, so as to avoid problems such as displacement of the cable terminal 10 during the installation process.

[0025] Please refer to Figure 1-4 The cable clamp 101 also includes a positioning structure 14 located below the connection end 1 and connected to the connection end 1. The positioning structure 14 is L-shaped and has a positioning hole 6 on its lateral side. The mobile device can install the cable terminal 10 or the CPU by replacing the installation head at the end. The positioning hole 6 of the cable clamp 101 is used to cooperate with the first positioning pin 16 of the positioning fixture 201. The positioning hole 6 of the cable clamp 101 is used to correspond to the position and size of the first positioning pin 16 of the positioning fixture 201 to ensure that the cable can be correctly installed to the specified position at one time. When the clamping bracket 8 of the cable clamp 101 moves into place, that is, the positioning hole 6 of the cable clamp 101 is aligned with the first positioning pin 16 of the positioning fixture 201, and then pressed downward to achieve the installation of the cable terminal 10. The relative position and size relationship between the positioning hole 6 of the cable clamp 101 and the first positioning pin 16 of the positioning fixture 201 determines the installation accuracy of the cable terminal 10. Otherwise, if there is an offset between the position of the positioning hole 6 and the position of the first positioning pin 16 of the positioning fixture 201 , the CPU may be damaged or the cable terminal 10 may be damaged.

[0026] The cable clamp 101 ensures that during the installation of the cable terminal 10, the cable terminal 10 is clamped to the accurate position before being released, thereby avoiding the problem of displacement of the cable terminal 10 during the installation process, so as to fully ensure the relative level between the cable terminal 10 and the CPU, so that all pins are pressed into place at the same time after being in contact, thereby improving the installation accuracy and efficiency of the cable terminal 10, avoiding CPU displacement, and improving the yield rate of production installation.

[0027] In another embodiment, the present invention further provides a cable installation device, comprising the cable clamp 101 and the positioning fixture 201 as described above, please refer to Figure 4 The positioning fixture 201 includes: a positioning plate 15 matching the size of the CPU, and a first positioning pin 16 installed on the positioning plate 15, the position of the first positioning pin 16 corresponds to the installation position of the cable terminal 10 of the CPU, and the size of the first positioning pin 16 matches the size of the positioning hole 6 of the positioning structure 14 of the cable clamp 101, so that when the positioning hole 6 is aligned with the first positioning pin 16, the first positioning pin 16 can be inserted into the positioning hole 6 by pressing downward to achieve the positioning of the cable terminal 10, thereby avoiding the problem of displacement of the CPU or the cable terminal 10 during the installation process.

[0028] Specifically, the positioning hole 6 of the cable clamp 101 is used in conjunction with the first positioning pin 16 of the positioning fixture 201. When the clamping bracket 8 of the cable clamp 101 is moved into position, that is, the positioning hole 6 of the cable clamp 101 is aligned with the first positioning pin 16 of the positioning fixture 201, and then pressed downward to achieve the installation of the cable terminal 10. The mutual position and size relationship between the positioning hole 6 of the cable clamp 101 and the first positioning pin 16 of the positioning fixture 201 determine the installation accuracy of the cable terminal 10. Therefore, the position of the first positioning pin 16 corresponds to the installation position of the cable terminal 10 of the CPU, and the size of the first positioning pin 16 matches the size of the positioning hole 6 of the positioning structure 14 of the cable clamp 101. The length of the first positioning pin 16 is almost equal to the length of the positioning hole 6 of the cable clamp 101, ensuring that the positioning is completed before the cable terminal 10 contacts, so as to ensure that the first positioning pin 16 can be completely inserted into the positioning hole 6, and then the cable terminal 10 can be installed by pressing vertically downward. For example, if there are two groups of cables, each group of cables has four cable terminals 10, and the two groups of cables have a total of eight cable terminals 10, these eight cable terminals 10 need to be installed on the four cable terminals 10 on both sides of the CPU. The position of the first locating pin 16 of the positioning fixture 201 is determined according to the position of the four cable terminals 10 on both sides of the CPU. Preferably, the first locating pin 16 is located at the geometric midline position of the positioning fixture 201 and is parallel to the cable terminals 10 on both sides of the CPU, which is conducive to achieving accurate centering and rapid positioning of the cable terminals 10 on both sides of the CPU during installation, and ensuring that the installation accuracy and positioning accuracy of the cable terminals 10 on both sides of the CPU are almost consistent as much as possible, avoiding angle deviation, and helping to improve the installation accuracy of the cable terminals 10.

[0029] Furthermore, the positioning fixture 201 includes, in addition to the positioning plate 15 and the first positioning pin 16 installed on the positioning plate 15, corner structures 17 extending from the four corners of the positioning plate 15, respectively, and the corner structures 17 include second mounting holes 18 matching the second positioning pins at the four corners of the CPU. The shape of the corner structure 17 is a convex and concave type. In other words, the first side (such as the first side) of the positioning plate 15 is provided with a plurality of second mounting holes 18, each of which is provided with a plurality of second mounting holes 18 matching the second positioning pins at the four corners of the CPU. Figure 4 A pair of diagonal structures (on the upper side of the figure) have a concave portion facing a first direction (such as upward) and located on a second side (such as the upper side) opposite to the first side. Figure 4A pair of corner structures (the lower side of the first corner structure 17) has a recess facing the second direction (such as downward), and the first direction is opposite to the second direction. By combining and configuring the corner structures 17 with different directions, the fool-proof function of the four corner structures 17 is achieved to avoid the problem of the positioning fixture 201 being placed in the wrong direction. At the same time, the corner structures 17 are chamfered, which is convenient for installation. When the CPU is installed in place, the four corner structures 17 of the positioning fixture 201 are correctly aligned with the four second positioning pins of the CPU according to the shape of the corner structures 17 and pressed downward, so that the four second positioning pins of the CPU are inserted into the mounting holes of the four corner structures 17 of the positioning fixture 201, so as to accurately fix the positioning fixture 201 on the CPU.

[0030] Please refer to Figure 1-4 The cable clamp 101 of the cable installation device includes a clamping bracket 8; a positioning structure 14 connected to the clamping bracket 8, the positioning structure 14 has a positioning hole 6 for receiving a first positioning pin 16; a cam shaft 13 passing through the clamping bracket 8 and a thumbwheel 7 connected at both ends thereof, the thumbwheel 7 being used to rotate forward or reversely when subjected to an applied force; a pair of movable components 5 supported by the clamping bracket 8, the pair of movable components 5 being pivotally connected to each other, each movable component 5 including a first end 2 located on the side of the cam shaft 13, the first end 2 being against or not against the cam shaft 13 when the thumbwheel 7 rotates forward or reversely; a second end 3 opposite to the first end 2, when the first end 2 is against the cam shaft 13, the pair of movable components 5 can be pushed to pivot relative to each other so that the pair of second ends 3 clamp the cable terminal.

[0031] In some embodiments, the cable clamp 101 includes a connecting end 1, which is located above the cam shaft 13 and connected to the clamping bracket 8, and a positioning structure 14 is located below the connecting end 1 and connected to the connecting end 1. The positioning structure 14 is L-shaped and has a positioning hole 6 on its lateral edge.

[0032] In some embodiments, the connection end 1 includes: an interface 4 that can be connected to a mobile device, and the interface 4 is used to connect to the mobile device to move the cable clamp 101 to a target position.

[0033] In some embodiments, the pair of second ends 3 are connected by a spring, which is used to bias the pair of second ends away from each other and be in a tightened state when the first end 2 abuts against the cam 12 , so that the pair of second ends 3 clamp the cable terminal 10 .

[0034] In some embodiments, a pair of movable components 5 are provided with opposite first mounting holes 9 , and the pair of movable components 5 are installed on both sides of the clamping bracket 8 via mounting shafts 11 passing through the first mounting holes 9 and form a four-sided supporting structure with the clamping bracket 8 .

[0035] In some embodiments, the camshaft 13 includes a cam 12 located in the middle of the camshaft 13 , and the first end 2 may or may not abut against the cam 12 of the camshaft 13 when the thumbwheel 7 rotates forward or reversely.

[0036] The positioning fixture 201 of the cable installation device is used in conjunction with the cable clamp 101 to position the cable during installation and maintain the installation level, thereby avoiding problems such as displacement of the cable terminal 10 during installation, and fully ensuring the relative level between the cable terminal 10 and the CPU, so that all pin needles are pressed into place at the same time after contact, thereby improving the installation accuracy and efficiency of the cable terminal 10, avoiding CPU displacement, and improving the yield rate of production installation.

[0037] In another embodiment, the present invention provides a positioning fixture 201, including a positioning plate 15, the size of the positioning plate 15 matches the size of the CPU; and a first positioning pin 16 installed on the positioning plate 15, the position of the first positioning pin 16 corresponds to the installation position of the cable terminal 10 of the CPU, and the first positioning pin 16 is used to be inserted into the positioning hole 6 of the cable clamp 101 above to install the cable terminal 10 to the corresponding position of the CPU. It can be understood that the positioning fixture 201 can also have other design structures, which will not be repeated here.

[0038] The positioning jig 201 is used in conjunction with the cable clamp 101. The cable clamp 101 ensures that during the installation of the cable terminal 10, the cable terminal 10 is clamped to the accurate position and then released. The positioning jig 201 is used to position the cable during installation and maintain the installation level, avoiding problems such as displacement of the cable terminal 10 during installation, so as to fully ensure the relative level between the cable terminal 10 and the CPU, so that all pin needles are pressed into place at the same time after being in contact, thereby improving the installation accuracy and efficiency of the cable terminal 10, and also avoiding CPU displacement, thereby improving the yield rate of production installation.

[0039] In another embodiment, the specific process of implementing cable installation by the cable installation device of this embodiment is as follows: Figure 5 As shown, Figure 5The diagram shows a state diagram of the cable terminals 10 being installed on both sides of the CPU. The installation of the SMP (Sub-Miniature Push-On) cable to a specific position of the CPU is used as an example for explanation. The cable terminal 10 of the SMP cable is a B2B structure. One end of the SMP cable is installed at the rear end of the chassis, and the other end has two groups of cables, each group of cables has four cable terminals 10, and the two groups of cables have a total of eight cable terminals 10. These eight cable terminals 10 need to be installed on four cable terminals 10 on both sides of the same CPU, respectively. Since the installation space of the cable terminal 10 is small and needs to be installed horizontally, the CPU is first installed in place, and then the positioning fixture 201 is installed on the CPU and in place. Specifically, the positioning plate 15 of the positioning fixture 201 is aligned with the CPU, and the second mounting hole 18 of the positioning fixture 201 is installed on the second positioning pins at the four corners of the CPU to accurately fix the positioning fixture 201 on the CPU to avoid damage to the interface or cable terminal 10 on the CPU. The interface 4 of the connecting end 1 of the cable clamp 101 is connected to the end of the mobile device, and the SMP cable terminal 10 is installed to the second end 3 of a pair of movable parts 5 of the cable clamp 101, and a positive force is applied to the dial wheel 7 of the cable clamp 101 to rotate the dial wheel 7 in the positive direction, so that the first end 2 of the pair of movable parts 5 abuts against the cam shaft 13 so that the second end 3 clamps the cable terminal 10, and the cable clamp 101 is moved vertically downward by the mobile device so that the positioning hole 6 of the positioning structure 14 of the cable clamp 101 is aligned with the first positioning pin 16 of the positioning fixture 201 and pressed downward with force, and then a reverse force is applied to the dial wheel 7 of the cable clamp 101 to rotate the dial wheel 7 in the reverse direction, so that the first end 2 of the pair of movable parts 5 does not abut against the cam shaft 13 so that the second end 3 releases the cable terminal 10, and then the cable clamp 101 is connected and lifted to complete the installation of a cable terminal 10, and the cable clamp 101 is moved to another position by the mobile device. The above process is repeated until the eight cable terminals 10 of the SMP cable are respectively installed on the four cable terminals 10 on both sides of the CPU, and finally the positioning fixture 201 is removed from the CPU to complete the installation process of the CPU cable terminal 10.
