Description

Technical Field

[0001] The invention relates to an electric wire connector with a parallel connection function. Background Art

[0002] A wire connector is a device used to electrically connect wires. It generally includes several wiring units, each of which has several electrical connection parts for connecting with the wires. The electrical connection parts of the same wiring unit can be electrically connected through an electrical connection piece, so that when several wires are respectively connected to the several electrical connection parts of the wiring unit, the electrical connection piece can electrically connect these wires to each other.

[0003] At present, each wiring unit of conventional wire connectors generally operates relatively independently, that is, it can only electrically connect wires connected in the same wiring unit, but cannot electrically connect wires between different wiring units, and cannot achieve the effect of parallel connection. Of course, some wire connectors will deliberately configure more electrical connection parts in the same wiring unit to enable more wires to be electrically connected to each other, which can also achieve the effect of parallel connection. However, when the line environment changes, for example, when these wires need to be split and connected separately, the wire connector can only be replaced to adapt to this situation, which is not only troublesome to operate, but also brings about an increase in cost.

[0004] In addition, there is a splicing type wire connector currently on the market, in which the shells of several wire connectors can be connected by snaps or connectors. When the number of lines increases or decreases, the wire connectors can be assembled and disassembled to adapt to changes in the line environment. However, the wiring units of each splicing type wire connector still do not have the function of being connected in parallel with each other. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a wire connector with a parallel function, which can connect the wiring units of the wire connector in parallel and has better adaptability to the line environment.

[0006] To achieve the above-mentioned purpose, the present invention provides an electric wire connector with a parallel function, comprising a shell, on which a plurality of wiring units are arranged, each wiring unit comprises a plurality of electrical connection parts for connecting with the wires, the electrical connection parts of the same wiring unit are electrically connected through an electrical connection sheet, and the shell is provided with a socket for inserting a conductive strip, the conductive strip can be inserted into the inner side of the shell along the socket and simultaneously contact and electrically connect with the electrical connection sheets of each wiring unit.

[0007] The beneficial effects of the present invention are as follows: the present invention has two usage states. When the conductive strip is separated from the wire connector, each wiring unit of the wire connector works independently. The electrical connection piece of each wiring unit electrically connects the electrical connection parts of the wiring unit together, so that the wires connected to the same wiring unit can be electrically connected to each other, but there is no electrical connection relationship between the wires connected to different wiring units. When it is necessary to connect the wires connected to the wiring units in parallel, the conductive strip can be inserted into the inner side of the shell along the jack on the outer side of the shell. When the conductive strip is inserted into the inner side of the shell, it can contact the electrical connection pieces of each wiring unit at the same time, so that the wiring units can be connected in parallel. The operation is very convenient and the adaptability to the line environment is strong. Since the conductive strip is inserted into the inner side of the shell, it will not affect the appearance of the wire connector. When the conductive strip is inserted into the inner side of the shell, the shell can also play a role in shielding and protecting the conductive strip, which can improve safety.

[0008] Furthermore, a plurality of cavities respectively used to accommodate each wiring unit are arranged on the shell, the shell includes a partition wall for separating adjacent cavities, the socket includes an opening arranged on the partition wall and an insertion port arranged on the outside of the shell, and the opening and the insertion port are arranged in aligned positions so that the conductive strip can be inserted into the opening and the insertion port at the same time.

[0009] The further advantage of the arrangement is that the cavities are separated by partition walls, so that each wiring unit can work relatively independently when not in parallel, and is not easily interfered with each other. When the conductive strip is inserted into the inner side of the shell along the jack, it can be straightly inserted into each cavity at the same time, which facilitates the conductive strip to contact and connect with the electrical connection piece in the cavity. The arrangement of the opening can guide the conductive strip, which facilitates the conductive strip to be accurately inserted into each cavity.

[0010] Furthermore, the cavity includes a guide inner wall, and the conductive strip can slide along the surface of the guide inner walls of the plurality of cavities while being inserted into the inner side of the shell along the insertion hole, and the guide inner walls of adjacent cavities are connected at the opening.

[0011] The advantage of the further arrangement is that the guide inner wall can play a certain guiding role in the insertion of the conductive strip, facilitating the insertion of the conductive strip, and can also prevent the conductive strip from bending and deforming during the insertion process.

[0012] Furthermore, the guide inner wall is provided with a convex rib for sliding with the conductive strip, the convex rib extending along the conductive strip insertion direction and penetrating the opening and the insertion port at the same time.

[0013] A further advantage is that the convex ribs can reduce the wear of the conductive strip when it slides along the guide inner wall surface, thereby improving the durability of the wire connector. Of course, the convex ribs can also provide a certain amount of interference for the plug-in fit between the opening, the insertion port and the conductive strip, providing a certain friction force for the conductive strip to prevent the conductive strip from falling out.

[0014] Furthermore, the electrical connection sheet includes an elastic contact portion extending to the insertion path of the conductive bar, and the elastic contact portion can be elastically pressed and contacted on the conductive bar when the conductive bar is inserted into the inner side of the housing.

[0015] The advantage of further configuration is that it can improve the conductive contact effect between the electrical connection sheet and the conductive strip, and improve the stability during parallel connection.

[0016] Furthermore, a chamfer is provided on one side of the elastic contact portion corresponding to the insertion direction of the conductive strip.

[0017] A further advantage of the arrangement is that when the conductive strip is inserted into the inner side of the shell, it collides with the chamfer of the elastic contact portion. The component force generated at the chamfer can drive the elastic contact portion to deform and disengage it from the insertion path of the conductive strip, which is not easy to interfere with the insertion of the conductive strip.

[0018] Furthermore, one end of the insertion opening facing the outer side of the shell has a flared opening, and the width of the flared opening gradually decreases along the insertion direction of the conductive strip.

[0019] A further advantage of the arrangement is that the flared opening facilitates the guiding and insertion of the conductive strip into the inner side of the housing.

[0020] Furthermore, it comprises the conductive strip, and the conductive strip is evenly provided with a plurality of notches along the length direction thereof.

[0021] A further advantage of the arrangement is that the notch arrangement facilitates cutting of the conductive strip to fit the length of the jack.

[0022] Furthermore, the conductive strip is included, and at least one end of the conductive strip has a tapered insertion portion.

[0023] The advantage of the further arrangement is that it is convenient to guide the conductive strip to be inserted into the socket.

[0024] Furthermore, several of the wire connectors can be combined and spliced ​​through connectors connected between their shells, and the conductive strips can be simultaneously inserted into the jacks of these wire connectors and simultaneously contact and electrically connect with the electrical connection pieces of each wiring unit of these wire connectors.

[0025] A further advantage of the arrangement is that a plurality of the wire connectors can be spliced ​​and combined through a connector, and the conductive strips can be simultaneously inserted into the jacks of these wire connectors, so that the wiring units of these wire connectors are electrically connected at the same time, which can improve the adaptability to the line environment.

[0037] The embodiment of the wire connector with parallel function of the present invention is as follows: Figure 1-10 As shown: it includes a shell 1, on which are disposed a plurality of wiring units, each of which includes a plurality of electrical connection parts 21 for connecting with electric wires, and the electrical connection parts 21 of the same wiring unit are electrically connected via an electrical connection sheet 22.

[0038] In this embodiment, there are two wiring units arranged on the housing 1, and each wiring unit has two electrical connection parts 21. Each wiring unit can electrically connect two wires at the same time. The two electrical connection parts 21 are conductive clips respectively connected to the two ends of the electrical connection piece 22. The operating handle 16 respectively arranged on the outer side of the housing 1 corresponding to each conductive clip can drive the conductive clip to clamp and fix the metal exposed part of the wire, and at the same time make the conductive clip contact and electrically connect with the wire. Of course, in other embodiments, the wiring units are not limited to two, and the electrical connection parts 21 on each wiring unit are not limited to two, and the number of electrical connection parts 21 on each wiring unit can also be different. In other embodiments, the electrical connection part 21 can also be connected by other components that can be electrically connected to the wire, such as clamping, winding, soldering, etc.

[0039] The housing 1 is provided with a socket 11 for inserting the conductive strip 3. The conductive strip 3 can be inserted into the inner side of the housing 1 along the socket 11 and simultaneously contact and electrically connect with the electrical connection piece 22 of each wiring unit. The conductive strip 3 can be a strip-shaped component made of any conductive material. Based on the contact and conductive effect between the conductive strip 3 and the electrical connection piece 22 of each wiring unit when the conductive strip 3 is inserted into the inner side of the housing 1, the wiring units on the housing 1 can be electrically connected, thereby realizing the parallel function, so that the wires connected to the electrical connection parts 21 of all wiring units can be electrically connected to each other. When the conductive strip 3 is not inserted into the socket 11, the wiring units on the housing 1 are not electrically connected to each other and can operate independently. When the conductive strip 3 is inserted into the inner side of the housing 1, the housing 1 can also play a role in shielding and protecting the conductive strip 3, which can improve safety.

[0040] In the present embodiment, the housing 1 is formed by upper and lower sub-housings (1a, 1b) being spliced ​​and combined with each other by means of a snap-fitting manner. A guide rail mounting seat 17 which is mounted and fixed in cooperation with the guide rail is integrally formed on the lower sub-housing 1b. A plurality of cavities 12 for accommodating each wiring unit are arranged on the housing 1. The plurality of cavities 12 are arranged and distributed along the same straight line direction. In the present embodiment, the number of cavities 12 is the same as that of the wiring units. These cavities 12 are arranged between the two sub-housings (1a, 1b) and are spliced ​​and formed by the two sub-housings (1a, 1b). With such a structure, the wiring units can be conveniently installed in the cavities 12. The housing 1 includes a partition wall 13 for separating adjacent cavities 12. The jack 11 includes an opening 111 arranged on the partition wall 13 and an insertion port 112 arranged on the outer side of the housing 1. The opening 111 and the insertion port 112 are arranged at mutually aligned positions so that the conductive strip 3 can be simultaneously inserted into the opening 111 and the insertion port 112 (such as Fig.10As shown), in this embodiment, there are two insertion ports 112 on the shell 1, of course, in other embodiments, there can also be one. When there is only one insertion port 112, the conductive bar 3 can only be inserted into the shell 1 in one direction. When the conductive bar 3 is inserted and conflicts with the shell 1, it indicates that the conductive bar 3 has been inserted into place; when there are two insertion ports 112, they are respectively arranged at the two ends of the jack 11, and the conductive bar 3 can be inserted into the shell 1 along any insertion port 112, which facilitates the insertion and removal of the conductive bar 3.

[0041] like Figure 7 , 10 As shown, the cavity 12 includes a guide inner wall 14, which is the bottom inner wall of the cavity 12. The conductive strip 3 can slide along the surface of the guide inner walls 14 of the plurality of cavities 12 while being inserted into the inner side of the housing 1 along the insertion hole 11. In this embodiment, the guide inner wall 14 is preferably a flat end surface, and of course it can also be an arc surface in other embodiments. Its specific shape is preferably adapted to the contour of the conductive strip 3. The guide inner walls 14 of adjacent cavities 12 are connected at the opening 111. The guide inner walls 14 of the plurality of cavities 12 are preferably arranged on the same plane so that they can better slide with the conductive strip 3. The guide inner wall 14 is provided with a convex rib 141 for sliding with the conductive strip 3. The convex rib 141 extends along the insertion direction of the conductive strip 3 and is simultaneously penetrated in the opening 111 and the insertion port 112.

[0042] like Figure 4 , Figure 7-8 As shown, the electrical connection sheet 22 includes an elastic contact portion 221 extending to the insertion path of the conductive strip 3. The elastic contact portion 221 is formed by bending the middle portion of the conductive strip 3 in an arch shape and has a certain elasticity. The extension to the insertion path of the conductive strip 3 specifically refers to the extension to a position aligned with the opening 111 and the insertion port 112. The elastic contact portion 221 can be driven to deform and shrink when the conductive strip 3 is inserted into the inner side of the housing 1 and elastically press and contact the conductive strip 3. The elastic contact portion 221 is arranged on one side corresponding to the insertion direction of the conductive strip 3. There is a chamfer 2211. In the present embodiment, since there are two insertion openings 112, the conductive bar 3 can be inserted into the inner side of the shell 1 along two opposite directions. Therefore, the chamfers 2211 on the elastic contact portion 221 are also correspondingly set to two. The chamfers 2211 are inclined relative to the insertion direction of the conductive bar 3. When the conductive bar 3 is inserted and contacts the chamfer 2211 of the elastic contact portion 221, the component force of the force when the conductive bar 3 is inserted can drive the elastic contact portion 221 to deform and disengage from the insertion path of the conductive bar 3, so that the insertion of the conductive bar 3 is smoother.

[0043] like Figure 4 , Figure 6As shown, the insertion opening 112 has a flared opening 15 at one end facing the outer side of the housing 1 , and the width of the flared opening 15 gradually decreases along the insertion direction of the conductive strip 3 . The flared opening 15 is convenient for guiding the conductive strip 3 to be inserted into the jack 11 .

[0044] The embodiment of the present invention also includes the conductive strip 3, on which a plurality of notches 31 are evenly distributed along the length direction, and the distance between adjacent notches 31 is preferably the same as the distance between adjacent openings 111 or between adjacent openings 111 and insertion openings 112, and at least one end of the conductive strip 3 has a tapered insertion portion 32. When the conductive strip 3 is inserted into the inner side of the housing 1, it can form an anti-rotation plug-in fit with the housing 1, and the anti-rotation fit between the conductive strip 3 and the housing 1 can be achieved by the shape profile of the plug-in fit between the conductive strip 3 and the opening 111 and / or between the conductive strip 3 and the insertion opening 112, for example, a polygon or an ellipse can be adopted. In this embodiment, the cross-sectional profile of the conductive strip 3 in the width direction is a rectangle, and the opening 111 and the insertion opening 11 are also correspondingly rectangular, and the two oppositely arranged flat end faces of the conductive strip 3 are respectively in contact with the guide inner wall 14 and the elastic contact portion 221, which can improve the stability of the conductive strip 3, prevent shaking, and improve the conductive contact effect.

[0045] Another embodiment of the present invention is Fig.11 As shown: the main difference between it and the previous embodiment is that several of the wire connectors 10 can be combined and spliced ​​through the connecting piece 4 connected between their shells. In this embodiment, the connecting piece 4 is a guide rail, through which several of the wire connectors 10 can be connected side by side and their jacks 11 can be in a relatively aligned position. In other embodiments, the connecting piece 4 can be a buckle, bolt, etc. that can connect two adjacent wire connector shells, or it can be a mounting plane that can keep the positions of these wire connectors relatively fixed (when several wire connectors are installed and fixed on the mounting plane at the same time, their positions can be kept relatively fixed), and the conductive strip 3 can be simultaneously inserted into the jacks 11 of these wire connectors 10 and simultaneously contact and electrically connect with the electrical connecting pieces of each wiring unit of these wire connectors 10, so that all the wiring units of these wire connectors 10 can be connected in parallel at the same time.

[0046] The above embodiment is only one of the preferred specific embodiments of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
