Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a power connector. Background Art

[0002] In order to avoid cable contact and ensure insulation safety, traditional power connectors usually have copper bars for connecting cables on both sides of the insulating plate. Since the two connectors of the connector need to be arranged on the same horizontal line (either horizontally or vertically) to facilitate the subsequent connection of the terminals, at least one of the copper bars on both sides of the insulating plate needs to be extended and bent so that the two copper bars can contact and conduct electricity with the two connectors, which will increase the length of the connector. In addition, since the bent part of the copper plate and the connector itself need to occupy a certain space, this will increase the height of the connector. Therefore, the length and height of the traditional power connector are limited, making it difficult to fit in a small space and inconvenient for users to move and transport. Utility Model Content

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figure 1 and Figure 2As shown, a power connector according to an embodiment of the utility model comprises an insulating member 100 made of plastic, rubber or polymer synthetic material, two conductive connecting members 200 , two copper bars 300 and a housing 400 , and a partition 110 is provided on one side of the insulating member 100 .

[0034] Reference Figure 2 and Figure 3 As shown, it can be understood that the two connectors 200 are respectively installed in the insulating member 100, and the connector 200 includes a columnar outer cylinder 220 and a cylindrical hollow conductive grid 230. The conductive grid 230 is installed in the outer cylinder 220, that is, the outer wall of the conductive grid 230 abuts against the inner wall of the outer cylinder 220.

[0035] The connector 200 is configured as an outer tube 220 with a conductive grid 230, which can simplify the structure of the connector 200 and facilitate the assembly of the connector. After the connector 200 is installed on the insulating member 100 and connected to the copper busbar 300, due to the hollow structure of the conductive grid 230 itself, the connector can cooperate with the external male terminal to achieve circuit conduction. In addition, the middle section of the conductive grid 230 can also be retracted inwardly, so that the conductive grid 230 has a certain elasticity and can hold the external male terminal inserted into the conductive grid 230 tightly, thereby improving the stability of the connector.

[0036] Reference Figure 4 As shown, it can be understood that the middle plane of the height of the cylindrical conductive grid 230 in the radial direction is a symmetry plane. After the two connectors 200 are respectively installed on the insulating member 100, the symmetry planes of the two conductive grids 230 are coplanar, that is, the centers of the two conductive grids 230 are in the same plane.

[0037] The symmetric surfaces of the two conductive grids 230 are arranged coplanarly, and when the connector is plugged in or out, the two connectors 200 are subjected to force synchronously, the plugging and unplugging force is evenly distributed, and the plugging and unplugging feel is smooth and uniform. There will be no problems such as eccentric distribution of plugging and unplugging force due to misalignment of external terminals, resulting in poor connector contact, unstable connection, etc., and the reliability of the connector is guaranteed.

[0038] Reference Figure 3 and Figure 4 As shown, it can be understood that the insulating member 100 is provided with two second through holes 101, and the two connecting members 200 are respectively installed in the two second through holes 101, and one end of the connecting member 200 protrudes from the end surface of the insulating member 100 along the height direction of the insulating member 100 and forms a first connecting portion 210, that is, one end of the connecting member 200 passes through the outside of the insulating member 100 and is provided with a first connecting portion 210.

[0039] The two first connection parts 210 corresponding to the two connecting parts 200 are centrally symmetrically distributed on both sides of the insulating part 100. The two connecting parts 200 are respectively provided with a socket 201, and the socket 201 is an open hole structure that passes through the conductive grid 230 along the height direction of the insulating part 100 (that is, the axial direction of the outer tube 220). The first connection part 210 and the outer tube 220 are integrally formed. The first connection part 210 is used for subsequent connection with the copper bus 300. The first connection part 210 can be connected with the copper bus 300 by snap-fitting, screwing, welding, etc., which will not be repeated here.

[0040] Among them, the insulating part 100 is provided with a limiting ring 120 which is integrally formed with the insulating part 100. The limiting ring 120, the second through hole 101 and the connecting part 200 are arranged in a one-to-one correspondence. The limiting ring 120 is located on one side of the corresponding second through hole 101 to limit the connecting part 200 along the height direction of the insulating part 100. The two limiting rings 120 corresponding to the two connecting parts 200 are distributed on both sides of the insulating part 100 in a centrally symmetrical manner; and the limiting ring 120 can increase the electrical clearance and creepage distance between the two connecting parts 200, thereby effectively improving the safety of the connector.

[0041] In other words, along the height direction of the insulating member 100, the insulating member 100 is provided with a limiting ring 120 on both sides thereof, and each limiting ring 120 is respectively provided on one side of the corresponding second through hole 101, thereby limiting the movement of the connector 200 in the corresponding second through hole 101 along the height direction of the insulating member 100. Specifically, the limiting ring 120 is provided with an inner hole for inserting the external male terminal, and the aperture of the inner hole is smaller than the outer diameter of the outer cylinder 220 to ensure that the limiting ring 120 can limit the connector 200.

[0042] By providing the limiting ring 120, the connector 200 is limited and positioned without affecting the connection between the external male terminal and the conductive grid 230 in the connector 200, so as to avoid the user inserting the connector 200 too much into the second through hole 101 when installing the connector 200, causing the first connecting part 210 to retract into the second through hole 101, affecting the subsequent connection between the first connecting part 210 and the copper bus 300, thereby improving the overall assembly convenience of the connector.

[0043] In addition, since the first connecting portion 210 itself protrudes from the outside of the insulating member 100 and is symmetrically arranged on both sides of the insulating member 100, and the limiting ring 120 also protrudes from the end surface of the insulating member 100 and is symmetrically arranged on both sides of the insulating member 100, that is to say, after the two connecting members 200 are installed, along the height direction of the insulating member 100, the end surfaces on both sides of the insulating member 100 protrude to form a limiting ring 120 and a first connecting portion 210 respectively. The limiting ring 120 reasonably utilizes the outer space of the insulating member 100 to limit the connecting member 200 without significantly increasing the height and length dimensions of the insulating member 100, thereby effectively improving the structural tightness of the insulating member 100.

[0044] Reference Figure 2 and Figure 3 As shown, it can be understood that the two copper bars 300 are respectively located on both sides of the partition 110, and a second connecting portion 320 is protruded from one side of the copper bar 300. Since the two first connecting portions 210 are symmetrically arranged on both sides of the insulating member 100, the two copper bars 300 can also be symmetrically arranged about the center of the partition 110 so that the second connecting portion 320 is correspondingly connected to the first connecting portion 210, wherein the first connecting portion 210 is an annular clamping block 211, and the second connecting portion 320 is a clamping ring 321, and the clamping block 211 and the clamping ring 321 are plugged into each other.

[0045] The first connection part 210 is set as a clamping block 211, and the second connection part 320 is set as a clamping ring 321, which can effectively simplify the structure of the copper bar 300 and the connection structure between the copper bar 300 and the connector 200, facilitate the user to process and assemble the copper bar 300, and effectively improve the assembly efficiency of the connector. In addition, since the second connection parts 320 of the two copper bars 300 are respectively connected to the first connection parts 210 on both sides of the insulating member 100, the second connection parts 320 do not need to be extended and bent, which can reduce the material cost of the copper bar 300, thereby reducing the production cost of the connector.

[0046] It should be supplemented that the outer side wall of the annular block 211 may also be provided with a spline texture, which may increase the friction between the block 211 and the card ticket, and further improve the connection tightness between the connector 200 and the copper busbar 300 .

[0047] The copper bar 300 is connected with a plurality of cables 310. Specifically, the plurality of cables 310 are arranged along the width direction of the copper bar 300 (i.e., the width direction of the connector) and are respectively welded and fixed to the copper bar 300. The cables 310 are located between the copper bar 300 and the partition 110 and extend toward the side of the copper bar 300 away from the connector 200. The plurality of cables 310 are arranged along the width direction of the copper bar 300, and the installation space in the width direction of the connector is reasonably utilized to ensure that the connector has a reasonable shape and volume while ensuring that the connector has sufficient power supply. The cables 310 are arranged between the copper bar 300 and the partition 110, so as to avoid contact friction between the cables 310 and the housing, which affects the stable installation of the cables 310.

[0048] Reference Figure 1 and Figure 3 As shown, it can be understood that the insulating member 100 is provided with two limit plates 130, the limit plates 130 are perpendicular to the insulating plate and extend toward both sides of the insulating plate, and the two limit plates 130 are symmetrically arranged on both sides of the partition 110. After the copper busbar 300 is installed, a limit groove is formed between the limit plate 130, the partition 110 and the copper busbar 300, and the portion where the cable 310 is connected to the copper busbar 300 is accommodated in the limit groove.

[0049] By setting the limiting plate 130, the limiting plate 130 cooperates with the partition plate 110 and the copper busbar 300 to limit the parts where the multiple cables 310 are connected to the copper busbar 300, so that the ends of the cables 310 are restricted and accommodated in the limiting grooves, avoiding the multiple cables 310 from being scattered and tangled.

[0050] Reference Figure 1 and Figure 2 As shown, it can be understood that the housing 400 is sleeved on the insulating member 100 and the copper bar 300. Specifically, the two opposite sides of the two limit plates 130 are respectively provided with second buckles 131, and the two sides of the housing 400 are symmetrically provided with second card slots 402. The second buckles 131 correspond to the second card slots 402 one by one and are engaged with each other. One side of the housing 400 is provided with an opening for the cable 310 to pass through. The housing 400 is provided with two first through holes 401, and the two first through holes 401 are respectively connected with the two jacks 201.

[0051] By providing the second buckle 131 and the second slot 402 , the tightness of the connection between the housing 400 and the insulating member 100 can be effectively improved, thereby preventing the housing 400 from loosening and affecting user use.

[0052] Reference Figure 2 and Figure 5As shown, it can be understood that the power connector also includes two conductive terminals 500, and the conductive terminals 500, the first through holes 401 and the connecting member 200 are arranged in a one-to-one correspondence. The conductive terminals 500 are inserted into the corresponding first through holes 401 and are plugged into and matched with the corresponding sockets 201 of the connecting member 200.

[0053] By setting the conductive terminal 500, after the conductive terminal 500 is installed, the conductive terminal 500 can be connected to the external female terminal to achieve circuit conduction, and the original female terminal type connector is converted into a male terminal type connector. The connector can be connected to the external male terminal, and can also be connected to the external female terminal through the conductive terminal 500, thereby expanding the connection objects of the connector and further improving the applicability of the connector.

[0054] Reference Figure 2 and Figure 6 As shown, it can be understood that the outer wall of the conductive terminal 500 is provided with a retaining ring 510 , the retaining ring 510 is arranged around the conductive terminal 500 , and the retaining ring 510 abuts against the outer wall of the housing 400 .

[0055] By setting the retaining ring 510, when the user inserts the conductive terminal 500 into the socket 201, the retaining ring 510 and the outer wall of the shell 400 limit the position of the conductive terminal 500, ensuring that the lengths of the two conductive terminals 500 exposed from the shell 400 are consistent, avoiding problems such as poor contact and inappropriate installation caused by different lengths of the conductive terminals 500.

[0056] Continue to refer to Figure 2 and Figure 6 As shown, it can be understood that the housing 400 is connected to a detachable fixing frame 410, and the fixing frame 410 can be connected and fixed to the housing 400 by screwing, clamping, bonding, etc. The fixing frame 410 is provided with two clamping holes 4101 corresponding to the conductive terminals 500 one by one, and the fixing frame 410 is also provided with a groove for accommodating the retaining ring 510. The conductive terminal 500 is provided with a positioning platform 520, and the positioning platform 520 is located on the side of the retaining ring 510 away from the housing 400, and the outer side wall of the positioning platform 520 abuts against the inner side wall of the clamping hole 4101.

[0057] By providing the fixing frame 410, the fixing frame 410 cooperates with the housing 400 to clamp the conductive terminal 500 along the axial direction of the conductive terminal 500, thereby preventing the conductive terminal 500 from being separated from the plug hole 201, and effectively improving the installation stability of the conductive terminal 500. In addition, a positioning column 412 can be provided on the side of the fixing frame 410 away from the housing 400, and the positioning column 412 can be inserted into the external PCB board, thereby effectively improving the installation stability of the connector.

[0058] Reference Figure 2 and Figure 5As shown, it can be understood that a spring sheet 420 is provided on the side of the housing 400 facing away from the cable 310, an elastic arm 421 is provided at the center of the spring sheet 420, a first buckle 4211 is provided at one end of the elastic arm 421, a connecting plate 411 is provided on one side of the fixing frame 410, the connecting plate 411 is provided with a first slot 4111, and the first buckle 4211 is engaged with the first slot 4111.

[0059] By providing the first card slot 4111 and the first buckle 4211, the fixing frame 410 can be detachably installed. On the one hand, the connection structure of the first card slot 4111 and the first buckle 4211 is simple to assemble and easy to operate, which can further improve the convenience of connector assembly; on the other hand, the housing 400 and the fixing frame 410 adopt a snap-on structure, and the housing 400 and the insulating member 100 also adopt a snap-on structure, which can effectively improve the structural consistency of the connector. In addition, a pull ring 422 can be provided on the side of the spring 420 away from the fixing frame 410 for the user to pull and move the connector, effectively improving the user experience.

[0060] It can be understood that the first connection parts 210 of the two connectors 200 are centrally symmetrically arranged on both sides of the insulating member 100, and the user can use the copper busbar 300 of the same specification to be centrally symmetrically arranged, so as to connect with the two connectors 200 respectively, and there is no need to extend and bend the copper busbar 300, which effectively reduces the overall length of the connector; at the same time, the connector 200 is directly installed in the second through hole 101 inside the insulating member 100, and the first connection part 210 of the connector 200 protruding outside the insulating member 100 is also connected to the second connection part 320 of the copper busbar 300, so there is no need to set additional installation space outside the insulating member 100 or on the shell 400 to accommodate the connector 200, which effectively reduces the overall height of the connector. The connector 200 is arranged in the insulating member 100 and the first connection part 210 is centrally symmetrically arranged, which can effectively reduce the length and height of the power connector, realize the shortness of the connector, facilitate users to pick up and move the connector, improve the portability of the connector, and make the connector suitable for small spaces.

[0061] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
