Description

Technical Field

[0001] The application of this utility model generally belongs to a cable sorting system and relates to a cable clamp used for sorting and wiring, enabling cables such as wires and data lines to be arranged along a specific path.

Background Art

[0002] Cable clamps are common components in the electrical field. In the wiring process, in order to arrange cables along a specific path without interfering with each other, it is necessary to fix the cables along components such as circuit boards and walls and use cable clamps to prevent the cables from deviating from the predetermined arrangement route.

[0003] There are times when it is necessary to arrange the cables along the edge of the circuit board. In that case, cable clamps dedicated to edge wiring are usually used to fix the cables. Such cable clamps generally have a cable clamp base in the form of an elastic clamp that can clamp and fix the edge of the circuit board by elastic force. The cable clamp also has a cable clamp part for fixing the arranged cables, whereby the cables are arranged along the fixed route at the edge of the circuit board.

[0004] However, there are still some problems with such cable clamps. For example, the cable clamp base of the cable clamp may have insufficient clamping force. As a result, the cable clamp may move relative to the circuit board under the operation of the cable and even come off the edge of the circuit board. In the case of plastic cable clamps, especially after long-term use or exposure to high temperatures, corrosive environments, etc., material degradation may occur, resulting in a weakening of the clamping force of the cable clamp base, and thus the cables cannot be effectively fixed to the specified route.

[0005] Therefore, in order to solve the above problems, it is necessary to further improve the structure of the cable clamp dedicated to edge wiring.

Summary of the Invention

[0006] This utility model is provided to overcome the problems of cable clamps in the prior art described above. Furthermore, this utility model provides a cable clamp having an improved structure that can firmly clamp the ends of the substrate to better secure the placed cable.

[0007] The cable clamp of this utility model includes a cable clamp body comprising a cable clamp portion and a clamp holder connected to the cable clamp portion, wherein the cable clamp portion is configured to clamp a cable, and the clamp holder includes a fixing component for fixing and is provided with a first engaging portion, and a latch member having a second engaging portion that can engage with the first engaging portion, the latch member having a clamp portion at one end that cooperates with the clamp holder to fix the cable clamp body in place.

[0008] In the cable clamp configuration described above, the clamp holder of the cable clamp body can function to secure the cable clamp to a mounting component such as a circuit board. The latch member is positioned such that when the latch member is attached to the cable clamp body, it can further secure the cable clamp body to the mounting component, thereby improving the tightness of the fixation.

[0009] In a specific embodiment, the first engaging portion is a latch member transport rail formed on the cable clamp body, and the second engaging portion is a rail housing groove formed on the latch member, and the latch member transport rail can be housed in the rail housing groove.

[0010] Preferably, the latch member transport rail is formed at the bottom of the clamp holder.

[0011] In other specific embodiments, the first engaging portion is a latch member housing groove formed in the cable clamp body, and the second engaging portion is the rod body of the latch member, which is insertable into the latch member housing groove.

[0012] Preferably, the latch member housing groove is formed at a position where the cable clamp portion intersects with the clamp holder.

[0013] To improve the mounting strength of the cable clamp in order to lock the relative positions of the first and second engaging portions after they have engaged with each other, a locking member is formed between the first and second engaging portions and is configured to allow the latch member to move in a first direction toward the cable clamp body relative to the cable clamp body and to prevent the latch member from moving in a second direction away from the cable clamp body.

[0014] In certain structures, the locking element includes at least one first locking tooth formed in a first engagement portion and at least one second locking tooth formed in a second engagement portion. The locking member can also be implemented as other known locking structures.

[0015] Preferably, the clamp portion of the latch member is a clamp sheet formed at one end of the latch member, and when the cable clamp is attached to the substrate, the clamp sheet contacts the substrate to fix the cable clamp body.

[0016] The fixing component within the clamp holder of the cable clamp body may be at least one of an elastic clamp, a magnetic member, and a connecting member.

[0017] When the fixing component is an elastic clamp, the elastic clamp may include a first clamp arm, a second clamp arm, and an elastic part connected between the first and second clamp arms, wherein the elastic force applied by the elastic part allows the first and second clamp arms to move closer to each other.

Embodiments for Implementing the Invention

[0020] To facilitate the understanding of the utility model, specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be understood that what is shown in the accompanying drawings is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Those skilled in the art can make various obvious modifications, variations and equivalent replacements of the present utility model based on the embodiments shown in the accompanying drawings. The technical features in the different embodiments described below can be arbitrarily combined when there is no contradiction, and all of these fall within the protection scope of the present utility model.

[0021] <First Embodiment> FIGS. 1 to 5b show a cable clamp 100 according to a first embodiment of the present utility model. The cable clamp 100 is configured to clamp a cable to be arranged and can be fixed to a component such as a substrate 1 to specify the arrangement path of the cable.

[0022] As shown in FIG. 1, the cable clamp 100 includes a cable clamp body 110 and a latch member 120. The latch member 120 is attached to the cable clamp body 110 and assists in fixing the cable clamp 100 to the substrate 1 by the cooperation between the cable clamp body 110 and the latch member 120.

[0023] FIG. 2 schematically shows a state in which the cable clamp 100 of the present utility model can be attached to the substrate 1 and shows the cable 2 clamped by the cable clamp 100. Here, the substrate 1 is illustrated in the drawing as an L-shaped substrate, but those skilled in the art will understand that the cable clamp 100 of the present utility model is also applicable to other cable attachment components, such as a flat board.

[0024] As shown in Figure 2, the cable clamp body 110 of the cable clamp 100 includes a cable clamp portion 111 and a clamp holder 112. An elastic strip 113 is formed on the cable clamp portion 111. When the cable 2 is inserted into the cable clamp portion 111, the elastic strip 113 elastically deforms, thereby clamping and fixing the cable 2 to the cable clamp 100.

[0025] The clamp holder 112 is connected to the cable clamp portion 111, and the illustrated clamp holder 112 is formed as an elastic clamp structure. Specifically, the illustrated clamp holder 112 includes two clamp arms, namely a first clamp arm 141 and a second clamp arm 142, with an elastic portion 143 connected between the first clamp arm 141 and the second clamp arm 142, which is, for example, an arc-shaped elastic portion as shown. The first clamp arm 141 and the second clamp arm 142 of the clamp holder 112 can be formed from the same material as the elastic portion 143, and preferably, the first clamp arm 141 and the second clamp arm 142 and the elastic portion 143 of the clamp holder 112 are formed integrally. Of course, the various components of the clamp holder 112 can also be made from different materials, which is also within the scope of this utility model. For example, the elastic part 143 is manufactured from an elastic material, while the first clamp arm 141 and the second clamp arm 142 are manufactured from other materials that may be inelastic.

[0026] The elastic part 143 applies a biasing force to the first clamp arm 141 and the second clamp arm 142 so that they move closer together. When the cable clamp 100 is fixed to the end of the substrate 1, the first clamp arm 141 and the second clamp arm 142 clamp the substrate 1 from both sides due to the elastic force of the elastic part 143, thereby fixing the cable clamp 100 to the substrate 1.

[0027] Furthermore, in addition to the configuration described above, the clamp holder 112 may take other forms that can be fixed to mounting components such as the substrate 1. For example, if the substrate 1 is a steel plate, the clamp holder 112 may be configured to include a magnet, so that the cable clamp 100 is fixed to the substrate 1 by magnetic attraction. Alternatively, an adhesive such as glue may also be applied to the clamp holder 112, or the clamp holder 112 may be fixed to the substrate 1 at least temporarily with an adhesive or the like during wiring. These variations of the clamp holder 112 also fall within the scope of this utility model.

[0028] Furthermore, as shown in Figure 2, the latch member transport rail 114 is formed in the cable clamp body 110, specifically, for example, at the bottom of the clamp holder 112. Correspondingly, a rail housing groove 121 is formed in the latch member 120, and the rail housing groove 121 has an opening at one end of the latch member 120 that faces the latch member transport rail 114 of the cable clamp body 110, and the cross-sectional shape of the rail housing groove 121 matches the cross-sectional shape of the latch member transport rail 114. This allows the latch member transport rail 114 to be inserted into the rail housing groove 121 through the opening.

[0029] During installation, the cable clamp body 110 clamps the edge of the substrate 1 from one side, and then the latch member 120 is sleeve-mounted onto the latch member transport rail 114 from the other side of the substrate 1 along the first direction. That is, the latch member transport rail 114 is inserted into the latch member 120. The rail housing groove 121 and the latch member transport rail 114 are fitted with locking members that match each other, and these locking members can fix the latch member transport rail 114, which is housed in the rail housing groove 121 of the latch member 120, to the latch member 120, thereby preventing the latch member 120 from easily separating from the cable clamp body 110 along the second direction opposite to the first direction.

[0030] Figure 3a is a cross-sectional view of the cable clamp 100 fixed to the substrate 1, and Figure 3b is an enlarged view of part A in Figure 3a. As can be clearly seen from the cross-sectional views shown in Figures 3a and 3b, at least one first locking tooth 131, preferably a plurality of first locking teeth 131, is formed on the latch member transport rail 114, and a second locking tooth 132 that fits with the first locking tooth 131 is formed at a corresponding position in the rail housing groove 121 of the locking member 120. The second locking tooth 132 is movable relative to the first locking tooth 131 along the first direction indicated by arrow D in Figure 3b. However, in the second direction opposite to the first direction, the first locking tooth 131 and the second locking tooth 132 are locked together.

[0031] In the illustrated structure, the exemplary locking members of the rail housing groove 121 and the latch member transport rail 114 are first locking teeth 131 and second locking teeth 132 in the form of spikes. However, other forms of locking structures known in the art can also be used to achieve a unidirectional locking function between the rail housing groove 121 and the latch member transport rail 114.

[0032] Furthermore, as shown in the drawing, the clamp sheet 122 is formed on one end of the latch member 120, away from the latch member transport rail 114. While the latch member 120 is sleeve-mounted on the latch member transport rail 114, the clamp sheet 122 abuts against the other side of the substrate 1 and cooperates with the cable clamp body 110 that clamps one side of the substrate 1, thereby allowing the cable clamp 100 to be more firmly fixed to the substrate 1.

[0033] Figures 4a to 4c show the various steps for attaching the latch member 120 to the cable clamp body 110. Figure 4a shows the latch member 120 being sleeve-mounted on the latch member transport rail 114. In Figure 4b, the latch member transport rail 114 is partially inserted into the rail housing groove 121 of the latch member 120. In Figure 4c, the latch member transport rail 114 of the cable clamp body 110 is fully fitted into the rail housing groove 121 of the latch member 120.

[0034] Furthermore, the cable clamp 100 of this utility model can be used to clamp either one cable 2 (Figure 5a) or two cables 2 (Figure 5b).

[0035] When in use, first the cable clamp body 110 of the cable clamp 100 is pushed from one side of the substrate 1 to the edge of the substrate 1, and the cable clamp body 110 clamps the substrate 1 so that it is fixed by the clamp holder 112. Next, the latch member 120 is fixed by a sleeve onto the latch member transport rail 114 from the other side of the substrate 1, and the latch member 120 is pushed in the direction toward the cable clamp body 110 until the clamp sheet 122 of the latch member 120 contacts the other side of the substrate 1. At this time, the latch member 120 is pushed further toward the cable clamp body 110, and the substrate 1 is clamped so that it is fixed between the clamp sheet 122 of the latch member 120 and the clamp holder 112.

[0036] Alternatively, the latch member 120 may also be sleeved onto the latch member transport rail 114 of the cable clamp body 110 before use, ensuring a large gap between the clamp sheet 122 of the latch member 120 and the clamp holder 112. When the clamp holder 112 clamps one side of the substrate 1, the latch member 120 is pushed toward the cable clamp body 110 until the clamp sheet 122 contacts the other side of the substrate 1.

[0037] <Second Embodiment> Figures 6 to 8 show a second embodiment of the present utility model. Here, components identical to those in the first embodiment are denoted by similar reference numerals. The following disclosure will focus on features that differ from the first embodiment and will not describe identical features in detail again. Unless otherwise specified, the features described in the first embodiment are equally applicable to the second embodiment.

[0038] As shown in Figure 6, the cable clamp 200 of the second embodiment includes a cable clamp body 210 and a latch member 220. A clamp sheet 221 is formed at one end of the latch member 220. In the cable clamp 200 of the second embodiment, unlike the first embodiment, the latch member 220 is rod-shaped. Accordingly, the cable clamp body 210 is provided with a latch member housing channel 213 into which the latch member 220 can be inserted.

[0039] In the structure shown in Figure 6, the latch member housing groove 213 is formed at the point where the cable clamp portion 211 of the cable clamp body 210 and the clamp holder 212 intersect. Furthermore, the extending direction of the latch member housing groove 213 is the same as the width direction of the cable clamp portion 211. Here, the so-called "width" direction of the cable clamp portion 211 refers to the direction substantially perpendicular to the extending direction of the cable 2 clamped to the cable clamp portion 211.

[0040] Figure 7a shows a cross-sectional view of the cable clamp 200 according to the second embodiment. Figure 7b shows an enlarged view of section B in Figure 7a. As can be seen from Figures 7a and 7b, a first locking tooth 231 is formed in the latch member housing groove 213 of the cable clamp body 210, and a second locking tooth 232 is formed correspondingly on the latch member 220. The first locking tooth 231 and the second locking tooth 232 may function in the same or similar manner as the first locking tooth 131 and the second locking tooth 132 functioned in the first embodiment.

[0041] Figure 8 is a schematic diagram showing how the cable clamp 200 of the second embodiment clamps the substrate 1 and secures the cable 2. As can be seen from Figure 8, the cable clamp 200 of this utility model can be fixed to the substrate 1 while suspended from it.

[0042] The cable clamp 200 of the second embodiment can be fixed to the substrate 1 in the same manner as the cable clamp 100 of the first embodiment.

[0043] <Third Embodiment> Figures 9 and 10 show a third embodiment of the utility model. Here, similar reference numerals are used to indicate features that are the same as those in the first and second embodiments. The following disclosure will focus on features that differ from the first and second embodiments, and will not describe the same features in detail again. Unless otherwise specified, the features described in the first and second embodiments are equally applicable to the third embodiment.

[0044] As shown in Figure 9, the cable clamp 300 of the third embodiment includes a cable clamp body 310 and a latch member 320. The cable clamp body 310 includes a cable clamp portion 311 and a clamp holder 312, and the latch member housing groove 313 is also formed in the cable clamp body 310. The latch member 320 is insertable into the latch member housing groove 313. Unlike the second embodiment, in the cable clamp 300 of the third embodiment, the latch member housing groove 313 extends along the thickness direction of the cable clamp portion 311. Here, the so-called "thickness" direction of the clamp holder 312 refers to the same direction as the extending direction of the cable 2 clamped by the cable clamp portion 311.

[0045] Similarly, the same locking elements as in the first and second embodiments, such as locking teeth, are also provided in the latch member housing groove 313 and on the latch member 320.

[0046] Preferred embodiments of this utility model have been described so far. Those skilled in the art can make obvious modifications and alterations based on these embodiments, all of which are also within the scope of this utility model. For example, in the cable clamp 100 of the first embodiment, the latch member transport rail 114 extends along the width direction of the cable clamp portion 111. However, the latch member transport rail 114 may also extend along the thickness direction of the cable clamp portion 111, as the latch member housing groove 313 extends in the third embodiment. In another example, as shown in Figures 5a and 5b, in a cable clamp 100 that clamps a substrate 1, the cable clamp portion 111 is located above the cable clamp body 110. However, the cable clamp 100 may also clamp the substrate 1 in a manner in which the cable clamp portion 111 is suspended from the substrate 1, as in the second and third embodiments.
