Description

Technical Field

[0001] The utility model relates to a power connection technology field, in particular to a needle-piercing power connection structure. Background Art

[0002] In the existing quick power connection structure, the purpose of power connection is achieved by piercing a conductive needle into a cable to contact a conductive body inside the cable. Since an electrical circuit is required for power consumption, at least two conductive needles are needed to connect to the conductive bodies in two cables. In the prior art, the two cables are arranged side by side, and the two conductive needles are also arranged side by side accordingly. Some are arranged vertically. No matter which arrangement method the two conductive needles adopt, the direction of piercing into the cable is fixed to ensure reliable piercing into the cable to contact the conductive body. In the actual use scenario, since the cable layout is fixed, the posture of the cable is fixed. Thus, the direction of the conductive needle piercing into the cable can only remain unchanged. Since some electrical facilities (such as point light sources) are combined with the conductive needles, the positional relationship between the electrical facilities and the conductive needles is fixed. After the conductive needles are connected to power, the positions of the electrical facilities will be fixed. However, in some occasions, the positions of the electrical facilities need to adapt to the usage requirements (such as the irradiation direction of the point light source). Therefore, the existing quick power connection structure cannot meet the requirements. Summary of the Invention

[0003] The invention object of the utility model is to provide a quick power connection structure that can overcome one or more of the above-mentioned disadvantages and can perform multi-directional power connection around the axis of the cable.

[0004] The utility model is realized as follows: it includes a conductive needle base, several conductive needles arranged on the conductive needle base, and a pressing member for pushing the conductive needles into the cable. The special feature is that several conductive needles are arranged in a row so that they can move relative to the cable along the axes of the conductive needles simultaneously under the action of the pressing member. The lengths of several conductive needles are different and match the conductive body layers at corresponding depths inside the cable. The outer surfaces of the bodies of the other conductive needles except the shortest one are insulators, so that the power connection parts at the ends of the conductive needles contact and connect to the target conductive body layers, while the bodies of the conductive needles cannot contact and connect to the conductive body layers they pass through. A limiting structure is arranged on the pressing member, so that when the pressing member stops at the limiting structure, the power connection parts at the ends of several conductive needles piercing into the cable are respectively connected to the corresponding conductive body layers.

[0005] When in use, the cable is first laid out according to the design requirements, and then the extrusion component is used to make the conductive needles pierce into the cable, and each conductive needle is inserted into the corresponding conductor of the cable in turn, and is connected to the corresponding conductor for electricity, so that the acquired electric energy is transmitted from the cable to the corresponding electrical facility (such as a light source arranged on the conductive needle holder, or an electrical facility connected to the conductive needle through a wire) through the conductive needle. The conductive needle body is wrapped with an insulator, so that the conductive needle body cannot contact and connect to the conductor layer it passes through, while the end connection point can be connected to the target conductor layer; since the conductive needle holder can be connected to the cable at various places around the cable, the position of the electrical facility fixedly connected to the conductive needle holder and the position relationship of the conductive needle can be changed at will according to requirements, thereby effectively enriching the decorative effect.

[0006] Preferably, the conductive needle body is cylindrical, and the conductive needle end portion is conical. In this way, the conductive needle can pass through the conductive layer, and at the same time, when the conductive needle end portion reaches the target conductive layer, the conical surface of the conductive needle end portion can lean against the conductive layer, so that the conical surface of the conductive needle end portion and the conductive layer have a large contact area, thereby ensuring reliable connection.

[0007] Compared with the prior art, the utility model has the advantages that the needles can penetrate into the conductive layers respectively along the diameter direction of the cable, each conductive needle can be effectively electrically connected with the corresponding conductive layer, and can be electrically connected in multiple directions around the cable axis.

[0011] The acupuncture electrical connection structure of the utility model is now described in further detail with reference to the accompanying drawings and embodiments:

[0012] Example 1: Figure 1 , 2As shown in the figure, the quick power connection structure of the present utility model is realized as follows. It includes a conductive pin base 1, several conductive pins 2 (the shape can be flat or cylindrical) arranged on the conductive pin base 1, and an extrusion member 3 for pushing the conductive pins 2 into the cable. The several conductive pins 2 are connected to an external electrical facility (such as a light source fixed on the conductive pin base 1) through wires to supply power to the electrical facility. The special feature is that the several conductive pins 2 are arranged in a row so that under the action of the extrusion member 3, they move relative to the cable 4 along the axis of the conductive pins 2 simultaneously. The several conductive pins 2 have different lengths and match the conductive layer 401 at the corresponding depth inside the cable 4. The outer surface of the body of the other conductive pins 2 except the shortest one is an insulator 5, so that the power connection part 201 at the end of the conductive pin 2 contacts and connects to the target conductive layer 401, while the body of the conductive pin 2 cannot contact and connect to the conductive layer 401 it passes through. A limiting structure 6 is provided on the extrusion member 3, so that when the extrusion member 3 stops at the limiting structure 6, the power connection parts 201 at the ends of the several conductive pins 2 inserted into the cable 4 are respectively connected to the corresponding conductive layers 401.

[0013] Preferably, the conductive pin base 1 is provided with a notch 7. The notch 7 is U-shaped, and the inner bottom 702 of the notch 7 is an arc surface to match the arc surface of the cable with a circular cross-section. The several conductive pins 2 are arranged in the middle of the bottom of the notch 7. In this way, when the cable 4 moves relative to the conductive pins 2, the conductive pins 2 can pierce into the cable 4 towards the center of the cable 4. The inner bottom of the notch 7 is an arc surface. In this way, when the cable 4 leans against the bottom of the notch 7, it will not be deformed, thus ensuring that each conductive pin 2 accurately reaches the corresponding conductive layer 401 and makes reliable contact and connection with each conductive layer 401.

[0014] Preferably, the upper part of the notch 7 has an external thread 701, and the extrusion member 3 is a nut. The nut is screwed into the upper part of the notch 7 to push the cable 4 arranged in the notch 7 towards the bottom of the notch 7, so that each conductive pin 2 pierces into the corresponding conductive layer 401 respectively and makes reliable contact and connection with each conductive layer 401.

[0015] Preferably, the limiting structure 6 is the stop surface at the bottom of the external thread 701, and the extrusion member 3 stops at the stop surface.

[0016] Preferably, the body 202 of the conductive pin 2 is cylindrical, and the power connection part 201 at the end of the conductive pin 2 is conical.

[0017] Preferably, the conductive pin 2 includes a columnar conductor 203 with a power connection part 201 at the end, and the insulator 5 wraps the body of the columnar conductor 203.

[0018] During use, first lay the cable 4 according to the design requirements, and then squeeze the component 3 to make the conductive needles 2 pierce into the cable 4. Each conductive needle 2 pierces into the corresponding conductive layer 401 of the cable 4 in sequence and is connected to the corresponding conductive layer 401 for power connection, so that the obtained electric energy is transmitted from the cable 4 through the conductive needles 2 to the corresponding electrical facilities (such as the light source arranged on the conductive needle base 1, or the electrical facilities connected to the conductive needles 2 through wires). The body 202 of the conductive needle 2 is wrapped with an insulator 5. In this way, while the body 202 of the conductive needle 2 cannot come into contact with the penetrated conductive layer 401 for power connection, the power connection part at the end 201 can be connected to the target conductive layer 401; since the conductive needle base 1 can be connected to the cable 4 around various parts of the cable 4, the positional relationship between the electrical facilities fixedly connected to the conductive needle base 1 and the position of the conductive needle 2 can be changed arbitrarily according to requirements, thus effectively enriching the decorative effect.
