It should be understood that what is shown in the accompanying drawings is only a preferred embodiment of the utility model and is not intended to limit the scope of the utility model. Various obvious modifications, variations and equivalent replacements of the utility model can be made by those skilled in the art based on the embodiments shown in the accompanying drawings. The technical features in the different embodiments described below can be arbitrarily combined if there is no contradiction, all of which fall within the scope of protection of this utility model.

<First Embodiment>
1 to 5b show a cable clamp 100 according to a first embodiment of the utility model. The cable clamp 100 is configured to clamp a cable to be arranged, and can be fixed to a component such as the substrate 1 in order to specify a cable arrangement route.

  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 cooperation between the cable clamp body 110 and the latch member 120.

  FIG. 2 schematically shows a state in which the cable clamp 100 of the utility model can be attached to the substrate 1, and shows the cable 2 clamped by the cable clamp 100. Here, the board 1 is illustrated as an L-shaped board in the drawing, but those skilled in the art will understand that the cable clamp 100 of the utility model can be applied to other cable mounting parts such as a flat board. To do.

  As shown in FIG. 2, the cable clamp main 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 111, the elastic strip 113 is elastically deformed, thereby clamping and fixing the cable 2 to the cable clamp 100.

  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, ie, a first clamp arm 141 and a second clamp arm 142, between the first clamp arm 141 and the second clamp arm 142. The elastic part 143 is connected, for example, there is an arc-shaped elastic part shown in the figure. The first clamp arm 141 and the second clamp arm 142 of the clamp holder 112 can be formed of the same material as the elastic part 143, and preferably the first clamp arm 141 and the second clamp arm of the clamp holder 112. The arm 142 and the elastic part 143 are integrally formed. Of course, the various components of the clamp holder 112 can also be made of different materials, which are also within the scope of this utility model. For example, the elastic portion 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 can be non-elastic materials.

  The elastic portion 143 applies a biasing force to the first clamp arm 141 and the second clamp arm 142 so that the first clamp arm 141 and the second clamp arm 142 approach each other. When the cable clamp 100 is fixed to the end portion of the substrate 1, the first clamp arm 141 and the second clamp arm 142 clamp the substrate 1 from both sides by the elastic force of the elastic portion 143, whereby the cable Fixing of the clamp 100 to the substrate 1 is realized.

  In addition to the above-described configuration, the clamp holder 112 may have another form that can be fixed to an attachment component such as the substrate 1. For example, when 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, and 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 are also within the scope of the utility model.

  Further, as shown in FIG. 2, a latch member conveyance rail 114 is formed on the cable clamp main body 110, specifically, for example, at the bottom of the clamp holder 112. Correspondingly, a rail receiving groove 121 is formed in the latch member 120, and the rail receiving groove 121 has an opening at one end of the latch member 120 facing the latch member conveying rail 114 of the cable clamp body 110. The cross-sectional shape of the rail receiving groove 121 matches the cross-sectional shape of the latch member conveyance rail 114. Thereby, the latch member conveyance rail 114 can be inserted into the rail accommodating groove 121 through the opening.

  During installation, the cable clamp body 110 clamps the edge of the substrate 1 from one side of the substrate 1 and then the latch member 120 is on the latch member transport rail 114 along the first direction from the other side of the substrate 1. A sleeve is attached. That is, the latch member conveyance rail 114 is inserted into the latch member 120 of the latch member 120. The rail receiving groove 121 and the latch member conveying rail 114 are provided with locking members that coincide with each other, and the latch member conveying rail 114 received in the rail receiving groove 121 of the latch member 120 is arranged by the locking member. The latch member 120 can be fixed with respect to the latch member 120, thereby preventing the latch member 120 from being easily separated from the cable clamp body 110 along the second direction opposite to the first direction.

  3a is a cross-sectional view of the cable clamp 100 fixed to the substrate 1, and FIG. 3b is an enlarged view of a portion A in FIG. 3a. As can be clearly seen from the cross-sectional views shown in FIGS. 3 a and 3 b, at least one first locking tooth 131, preferably a plurality of first locking teeth 131, is formed on the latch member transport rail 114, Second locking teeth 132 that match the locking teeth 131 are formed at corresponding positions in the rail receiving groove 121 of the locking member 120. The second locking teeth 132 are movable with respect to the first locking teeth 131 along the first direction indicated by the arrow D in FIG. However, in the second direction opposite to the first direction, the first locking teeth 131 and the second locking teeth 132 are locked to each other.

  In the illustrated structure, exemplary locking members of the rail receiving groove 121 and the latch member transport rail 114 are first locking teeth 131 and second locking teeth 132 in the form of barbs. However, other forms of locking structures known in the art can also be used to achieve a one-way locking function between the rail receiving groove 121 and the latch member transport rail 114.

  Further, as shown in the drawing, a clamp sheet 122 is formed at one end of the latch member 120 away from the latch member conveyance rail 114. While the latch member 120 is sleeved on the latch member conveyance rail 114, the clamp sheet 122 abuts on the other side of the substrate 1 and cooperates with the cable clamp body 110 that clamps one side of the substrate 1. Thus, the cable clamp 100 can be fixed to the board 1 more firmly.

  Various steps of attaching the latch member 120 to the cable clamp body 110 are shown in FIGS. 4a-4c. FIG. 4 a shows that the latch member 120 is sleeved on the latch member transport rail 114. In FIG. 4 b, the latch member conveyance rail 114 is partially inserted into the rail receiving groove 121 of the latch member 120. In FIG. 4 c, the latch member transport rail 114 of the cable clamp body 110 is completely contained in the rail receiving groove 121 of the latch member 120.

  Furthermore, the cable clamp 100 of the utility model can be used to clamp one cable 2 (FIG. 5a) or two cables 2 (FIG. 5b).

  In use, first, the cable clamp body 110 of the cable clamp 100 is pushed from one side of the board 1 to the end of the board 1, and the cable clamp body 110 is clamped so that the board 1 is fixed by the clamp holder 112. Next, the latch member 120 is fixed by a sleeve from the other side of the substrate 1 onto the latch member conveyance rail 114, and the latch member 120 is connected to the cable clamp until the clamp sheet 122 of the latch member 120 contacts the other side of the substrate 1. It is pushed along the direction toward the main body 110. At this time, the latch member 120 is further pushed toward the cable clamp body 110, and the substrate 1 is clamped to be fixed between the clamp sheet 122 and the clamp holder 112 of the latch member 120.

  Alternatively, the latch member 120 may also be sleeved on the latch member transport rail 114 of the cable clamp body 110 prior to use, ensuring a large gap between the clamp sheet 122 and the clamp holder 112 of the latch member 120. The 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.
