In the embodiment shown in conjunction with the drawings, the cable socket protective device 100 may include a base 10 and a force conversion structure 20, and the base 10 and the force conversion structure 20 are connected to each other in a length direction, i.e., an axial direction, of the cable 400 to securely hold the cable 400.
As shown in more detail in fig. 2, the chassis 10 may be placed around the jack 200A of the cable socket 200 and attached to a structure at the periphery of the jack 200A, for example, to a panel of the cable socket 200, or to a peripheral fuselage skin.
As a non-limiting example, the chassis 10 may include a cradle 11 and an attachment portion 12, wherein the cradle 10 is capable of holding the cable plug 300, and the attachment portion 12 is attached to a structure at the periphery of the jack 200A, for example, to a panel of the cable receptacle 200, or to a fuselage skin at the periphery.
In this example, the bracket 11 includes a plurality of spaced support feet, such as three support feet shown in the drawings that are spaced 120 ° apart from one another. In addition, these spaced apart support legs are connected together via binding member 13 such that binding member 13 firmly grips cable 400.
The bracket 11 and the restraining member 13 may be made of, for example, metal or composite material to ensure that they have sufficient rigidity to support the cable jack protection device 100 and the cable plug 300 and cable 400 held thereby.
In the embodiment shown in the drawings, the bracket 11 is a generally triangular sheet and may be hollowed out at the middle of the body to reduce the amount of material used and its weight as much as possible while ensuring strength. However, the present invention is not limited thereto, but may include various bracket types as long as it can achieve a predetermined supporting function.
In addition, as a non-limiting example, the restraining member 13 may be a disposable cable tie, as is common in the wiring field, so as to be able to perform the intended restraining and securing functions in a cost-effective and reliable manner.
As shown, the restraining member 13 may comprise two and be spaced apart in the circumferential direction so as to hold the respective spaced-apart brackets 11 together and form a predetermined internal space, which may be cylindrical or conical, depending on the circumferential dimension of the cable plug 300 held by the brackets 11.
Preferably, the internal space enclosed by the bracket 11 is adjustable to accommodate the circumferential dimensions of the cable plug 300. At this time, for example, it is only necessary to make the circumferential dimension of the binding member 13 adjustable, and the spacing between the supporting legs of the bracket 11 will vary with the circumferential dimension of the binding member 13, so that the cable plugs 300 of different outer diameters can be securely held.
In this example and as shown, the attachment portion 12 may include 3 suction cups equally spaced circumferentially around the receptacle 200A to attach the cable jack protection device 100 to the cable jack 200, and thereby to retain the cable plug 300 and cable 400 attached to the cable jack 200.
In an alternative embodiment, the attachment portion 12 may also be one or more hooks or the like to releasably attach the cable jack protection device 100 to the fuselage of an aircraft. At this time, the strength of one or more hooks is preferably selected as: firstly, it can be sufficient to carry the weight of the cable socket protection device 100 and the weight of the attached cable plug 300 and cable 400, and secondly, on that basis, if subjected to a certain amount of additional pulling force, can break or otherwise fail to detach from the fuselage structure, for example the fuselage skin.
As shown in the figures and according to a non-limiting embodiment of the present invention, the force conversion structure 20 is used to hold a cable 400 and is connected to the base 10 at a side remote from the cable socket 200. For example, the force conversion structure 20 may be fixedly connected to the base 10 at one end thereof by welding, bonding, or the like, thereby forming the integrated cable socket protection device 100.
The conversion of a non-axial pulling force (e.g., a lateral pulling force or a side-to-side pulling force) applied to the cable 400 held by the force conversion structure 20 into an axial pulling force is mainly achieved by the force conversion structure 20.
In the example shown in the figures, the force conversion structure 20 comprises a pulling member 21 and a cable fixing member 22, wherein the pulling member 21 is connected between the base plate 10 and the cable fixing member 22, and the pulling member 21 has an elongated structure to deflect in a lateral direction.
For example, the traction member 21 may include a plurality of spaced support bars, such as three support bars shown in the figures that are spaced 120 ° apart from each other. These spaced support bars are fixed at one end to the base 10 and connected together at the other end by a cable fixing member 22.
As a non-limiting example, the support bar may be a metal strip or a support bar made of a composite material, which is strong enough to hold the cable 400 while having a desired deflection elasticity, such that when the cable 400 is pulled, the support bar undergoes a certain deflection in its length direction, thereby converting a lateral or transverse force acting on the cable 400 into an axial or longitudinal force along the length direction of the cable 400, thereby ensuring reliable pulling of the cable plug 300 out of the jack 200A of the cable receptacle 200.
It will be appreciated that the attachment portion 12, e.g. the suction cup, will typically be detached from the cable socket 200 before the cable plug 300 is pulled out of the receptacle 200A of the cable socket 200.
By way of non-limiting example, the cable fixation member 22 may be a disposable cable tie as is common in the wiring art, such that the intended function can be achieved in a cost effective and reliable manner. In other embodiments, the cable fixation member 22 may also be a metal ring, buckle, or a ring, buckle structure, etc., of various composite materials with adjustable inner diameters.
Fig. 3 is a schematic view of a state of the cable socket protective device 100 when used to hold a cable 400 according to a non-limiting embodiment of the present invention.
As shown, the cable fixing member 22 firmly holds the cable 400 and makes the length of the cable 400 held between the cable fixing member 22 and the cable receptacle 200 larger than the distance between the cable fixing member 22 and the cable receptacle 200.
Therefore, it is possible to ensure that the pulling member 21 transmits the pulling force of the cable 400 to the base 10, thereby achieving reliable pulling out of the cable plug 300 from the insertion hole 200A of the cable receptacle 200.
