Description

Cable combination and manufacturing method thereof

The present invention relates to a cable combination, and more particularly to a cable combination having a protective cover.

At present, various portable electronic devices such as notebook computers, projectors, and players have been widely used and applied, and various electronic devices generally have a cable combination that is connected to a power source or other devices. The cable connector combination is a commonly used device in the above electronic device, and the frequency of use is very high. When moving, the cable combination of the cable connector or the electronic device connection is subjected to a large torsional stress, such as a line. The cable in the cable combination is damaged. Therefore, it is necessary to provide a method for enhancing the strength of the joint strength between the cable and the electronic device to protect the cable of the cable combination from damage, thereby improving the service life of the cable. Currently, the cable is usually used. The stress relief element is added to the joint of the connector to overcome the above problems. However, in the conventional technical solution, most of the general cable combinations are formed by directly forming the stress releasing component on the cable, and the stress releasing component on the covering cable can effectively protect the cable from being easily broken. Under certain special conditions, a certain section of the cable combination may be subjected to very large or high-frequency bending strength. During long-term use of the cable, the cable and the stress relief component may also be broken. The conventional cable combination may not meet the demand.

Therefore, it is necessary to provide a cable combination to overcome the above problems.

It is a primary object of the present invention to provide a cable combination having a higher bending strength.

In order to achieve the above object, the present invention is a cable assembly comprising a cable, a first protective sleeve and a second protective sleeve, the first protective sleeve having a receiving groove for receiving the cable and recessed inwardly from a surface thereof The second protective sleeve is formed in the receiving groove to fill a gap between the receiving groove and the cable.

In order to achieve the above object, the present invention may also be a method for manufacturing a cable assembly: (1) providing a cable and a first protective cover, the first protective cover having a receiving slot for receiving the cable and the same (2) the cable is received in the receiving groove; The second protective cover fills a gap between the receiving slot and the cable.

Compared with the prior art, the cable combination of the present invention has the following effects: improving the strength of the cable combination against bending.

Referring to the first to fourth figures, the cable assembly 100 of the present invention comprises a cable 1, a first protective cover 2 mounted on the cable 1, and a second protection between the first protective cover 2 and the cable 1. Set of 3.

In the present embodiment, the cable 1 includes at least one wire 12, an inner insulating layer 13 covering the wire 12, a braid 14 covering the inner insulating layer 13, and an insulating outer layer 15 covering the braid 14. In other embodiments, the cable 1 can be any of the prior art cables, such as only wires and insulating layers.

The first protective cover 2 has a substantially rectangular structure and is formed by plastic molding. In other modes, the first protective cover 2 may be other materials. The first protective cover 2 includes a receiving groove 21 extending through the front and rear surfaces. The cross section of the receiving groove 21 is composed of a plurality of intersecting or tangential circles as viewed from the front and rear surfaces, or the plurality of circles of the receiving groove 21 do not intersect or are tangent. Several circles are connected to each other. Of course, the receiving groove 21 is not limited to penetrate the front and rear surfaces, and can be bent and penetrated to other surfaces. The shape of the receiving groove 21 can be changed according to the shape of the cable 1, such as a flat shape, an elliptical shape, or the like. The number of the storage slots 21 is four. The cable 1 is inserted into the receiving slot 21, and the braided layer 14, the inner insulating layer 13 and the wires 12 of the cable 1 are exposed at one end of the first protective cover 2, and the insulating outer layer 15 is also exposed. The woven layer 14 is bent backward, and the partial woven layer 14 is located on the outer surface of the first protective cover 2, and the partial woven layer 14 is located in the adjacent receiving groove 21. The first protective cover 2 is also provided with a filling groove 22 which is recessed inward from its side surface and communicates with the receiving groove 21. The filling groove 22 penetrates through the opposite side surfaces of the first protective cover 2. The filling groove 22 and the receiving groove 21 are perpendicular to each other to facilitate molding the second protective cover 3 in the mold. The first protective cover 2 is also provided with a card slot 23 formed inwardly from its side surface. The card slot 23 may be formed on one of the side surfaces of the first protective cover 2 or may be disposed on the plurality of side surfaces. The card slot 23 can be used for snapping with some connecting devices, which is advantageous for keeping the devices of the cable combination more than 100 connected stable.

The second protective sleeve 3 is formed by plastic injection molding, and the gap between the receiving groove 21 and the cable 1 is filled in the self-filling groove 22, and the plurality of receiving grooves 21 intersecting the circular structure facilitates the second protective sleeve 3 to press the cable 1 . The gap between the housing groove 21 and the cable 1 is filled, and the filling groove 22 may be filled. The surface of the second protective cover 3 filling the filling groove 22 is flush with the first protective cover 2.

The steps of the method for manufacturing the cable assembly 100 of the present invention are as follows:

(1) Providing the cable 1 and the first protective cover 2 having the receiving groove 21 and the filling groove 22; the receiving groove 21 penetrates the front and rear surfaces of the first protective cover 2, and the filling groove 22 is inward from the side surface of the first protective cover 2. The recess is connected to the receiving groove 21;

(2) The cable 1 is received in the receiving slot 21;

(3) The second protective cover 3 is filled in the receiving groove 21 from the filling groove 22 by injection molding, and fills the gap between the receiving groove 21 and the cable 1 and fills the filling groove 22.

The cable 1 of the present invention double protects the cable 1 through the first protective cover 2 and the second protective cover 3, so that the cable assembly 100 can also have the effect of protecting the cable 1 under the condition of being subjected to a large external force.
