Description

Technical Field

[0001] The present invention relates to an improvement of a power supply and / or electric signal distribution device, and in particular to a device capable of providing power to a power socket and being suitable for the distribution of various electric signals, whether strong or weak. Background Art

[0002] Conventional power distribution systems in home and commercial environments provide power sockets with power outlets installed in wall cavities or surfaces at predetermined locations. The locations of such power sockets need to be selected in advance, and often subsequent requirements mean that the power sockets are installed in the wrong location and / or in insufficient quantity.

[0003] Invention patent CN200480028278.4 solves the above problems as an alternative to traditional systems. However, the thickness of the device is limited by the conductive elements, which restricts the installation of the device into office furniture. In addition, the complex assembly process incurs additional costs. Finally, the grounding path is inconsistent, which can cause grounding failure and / or static charge accumulation.

[0004] The present invention is an improvement on CN200480028278.4-Power distribution device. It involves improvements in grounding methods, elastic conductive elements, etc., so that a thinner and safer device can be developed, and the connector is also improved. The advantages of the present invention are simplified assembly, improved grounding methods, reduced parts costs, thin and light equipment, and significantly improved performance. Summary of the invention

[0005] According to one aspect of the present invention, a catheter comprises at least one elongated conductor, one end of the catheter has a power source and / or signal source access device, the catheter has an opening, a connector can be inserted into the opening and electrically connected to the at least one conductor;

[0006] A plurality of elastic conductive elements are arranged between the opening and the at least one conductor, the plurality of elastic conductive elements are electrically connected together and electrically connected to the ground line of the power source and / or signal source, at least one of the plurality of elastic conductive elements is arranged to be electrically connected to the ground line of the connector, and each elastic conductive element is supported separately and can be replaced by one of the connectors to provide a path to the at least one conductor.

[0007] Since the elastic conductive elements are supported separately, each elastic conductive element can be replaced individually by a connector, thereby providing a modular elastic conductive element, thereby achieving simpler assembly and replacement.

[0008] Preferably, the device further improves the structure of the elastic conductive element, which is an integrated structure that does not require assembly and can be completely manufactured by conventional methods (such as progressive stamping).

[0009] Preferably, the elastic conductive element directly forms a ground connector, even when it is not in operation. When the conduit is made of conductive material, it acts as an EMI shield. The elastic conductive element is in direct contact with the ground plane, and excess charge accumulation can be dissipated. In contrast, existing products have a possible charge accumulation causing electrostatic discharge. One side leg of each elastic conductive element is connected to an elongated conductor connected to the conduit to form a ground connector; if the conduit is made of conductive material, the elongated conductor is electrically connected to the conduit, or the conduit itself is directly electrically connected to one side leg of the elastic conductive element.

[0010] Preferably, the plurality of elastic conductive elements are separated from each other, and one connector only presses down one elastic conductive element; however, the elastic conductive elements are electrically connected.

[0011] The side legs of the elastic conductive element also include abutments to prevent the elastic conductive elements from overlapping when connected in series.

[0012] The improved structure allows the elastic conductive element to be completely flattened after being compressed, saving a lot of space, while improving the performance of the equipment and greatly reducing the thickness. The side legs of the elastic conductive element are arched, and each side leg has multiple bends, which are used to maintain the shape of the elastic conductive element, the correct deformation direction when compressed, and provide contact pressure. The two bends close to the adjacent surface help to reduce the length of the adjacent surface. When the adjacent surface is pressed down, the two bends act in series to ensure that the adjacent surface can be completely flat and in contact with the bottom surface of the catheter; the bends at the waist of the side leg ensure that the deformation direction of the elastic conductive element is accurate when it is compressed and increase the contact pressure; the two bends at the foot and the flat part are used for the sliding surface between the catheter grounding part.

[0013] The power and / or signal source access device includes a terminator and a terminator clamp, wherein the terminator clamp has a hollow portion to allow a capture function of the terminator clamp to latch onto the terminator.

[0014] The terminator comprises at least one electric conductor and a ground conductor, a shell, an insulator and a wire anchor; the ends of the electric conductor and the ground conductor are elastic bodies, preferably U-shaped elastic bodies, which increase contact pressure and reduce contact resistance.

[0015] Preferably, the electrical conductor of the terminator directly contacts the elongated conductor in the conduit with contact pressure to reduce contact resistance.

[0016] The terminal fixture includes a ground conductor chain, a shell, a fastener and a hollow part; the ground conductor chain is elastic, and uses the side wall of the hollow part as a fulcrum to electrically connect the ground conductor and the elastic conductive element of the terminal; the conductive fastener is mechanically connected to the conduit, which can play a backup grounding role; it is safer.

[0017] The catheter also has a plurality of grooves for installing an elongated conductor, a power source and / or a signal source access device, an elastic conductive element, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 Figure 2 An embodiment of a power / electrical signal distribution device is shown. This embodiment is composed of live and neutral conductors "300" (FIG. 2), insulation "400" (FIG. 2), ground conductor "14" (FIG. 2), elastic conductive element "12" (FIG. 1), a housing "36" (FIG. 1), a power entry terminator "100" (FIG. 1) and a terminator clamp "200" (FIG. 1). In addition, the housing "36" also has a groove for mounting purposes.

[0036] Figure 7 shows an example of this usage.

[0037] Figure 3 A connection method between a terminator "100" and a terminator fixture "200" is illustrated. A hollow portion "101" is present to allow a capture feature "201" of the terminal fixture to latch onto the terminator.

[0038] Figure 4 The components of a terminator "100" are shown. The terminator includes a hot conductor "102", a neutral conductor "104" and a ground conductor "106", a housing "109", an insulator "111" and a wire anchor "110". The U-shaped features "103" and "105" press against a surface "112" (Figure 5) and act as a spring to apply contact pressure. When in contact with "202", the ground contact "107" is bent to apply contact pressure. The fastener "108" is mechanically connected to "36".

[0039] Figure 5 The internal structure of the terminator "100" after assembly is shown.

[0040] Figure 6The components of a terminator anchor "200" are shown. It consists of a ground conductor link "202", a housing "204" and a fastener "205". The ground conductor link "202" is coupled to a hollow portion "203", "203" also serving as a fulcrum, allowing "202" to bend elastically when tightly coupled to "107". The fastener "205" is mechanically connected to the rail "36" and serves as an alternative grounding path.

[0041] Compared with the terminal fixture of the prior art, one of the major improvements of the present invention is that "102" and "104" directly contact the track conductor "300", which can reduce the contact resistance and thus reduce the heat generation. The grounding of the housing (Figure 21) in the present invention is more consistent and safe. The housing of the prior art product is finely processed, which will cause the housing grounding to be weak. In contrast, the grounding of the present invention is not only through the elastic grounding element, but also through the fastener "205", which provides additional safety assurance.

[0042] Figures 7 and 8 show embodiments of elastic conductive elements. Figure 7 shows a cross-sectional view of an elastic conductive element. The elastic conductive element can be made of any work-hardened conductive material, such as stainless steel. Figure 8 shows a series structure of multiple elastic conductive elements.

[0043] In Figure 7, each elastic conductive element is composed of a single piece of material with its bend located at a specific position.

[0044] Figures 9 to 13 illustrate the bend and its purpose. In Figure 9, "1" depicts a contact surface where a power point grounding connector connects the grounding member to a standard plug specific to each country. Preferably, the power point grounding connector is a dome-shaped conductive member surrounded by an insulating material, such as Fig.15 , as shown in item "20". The contact surface "1" must remain rigid during operation to ensure good contact.

[0045] "1" is reinforced by bends "2" and "3" in Figure 8. Bend "2" helps to reduce the length of the beam in "1", thereby reducing the deflection when a downward force is applied to this surface. Bend "3" is used to resist the force applied by bend "2" and correct the geometric changes caused by bend "2". The two bends "2" and "3" act in tandem to ensure that surface "1" can be completely flat with surface "10" (Figure 11). Fig.16The spring is shown in a fully flattened configuration. Bends "5" and "7" in Figure 13 also act in series to allow the spring to flatten while retaining the original geometry shown in Figure 7. Thus, "5" and "7" provide the necessary contact pressure for low resistance contact between the ground spring and the power point ground connector "20" (Figure 15).

[0046] Fig.17 The flattening of springs in power / electrical signal distribution devices is described, and Fig.18 The spring configuration when pressure is released is illustrated.

[0047] Bend "6" in FIG. 13 bends outward from cavity "11" in FIG. 7 to prevent the spring portion from collapsing from below. In addition, bend "6" increases bend "7", surface "10" and conductor "14" Fig.18 The contact pressure between them.

[0048] When the grounding spring is in operation, the bends "7" and "8" in Figure 11 serve as sliding surfaces between "14". The bend "8" also reduces the torsion experienced by the link "4" Figure 14 when the grounding spring is flattened or returns to its original shape. The abutment "9" in Figure 12 is to prevent the grounding springs in Figure 8 from overlapping when connected in series, such as Fig. 20 and 21 shown.

[0049] Bend "21" prevents the ground spring from hooking onto adjacent springs during operation.
