Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and specifically relates to an electrical connector that is easy to disassemble. Background Technology

[0002] In existing technology, a typical electrical connector includes: a connector housing, a control circuit board installed inside the connector housing, and power input lines integrally formed with the connector housing at both ends. The power input lines are electrically connected to the control circuit board, and the power input lines extending from the control circuit board extend into the lamp and are electrically connected to the light source of the lamp. Thus, the electrical connector supplies power to the lamp and can also connect two adjacent lamps. However, since the power input lines are integrally formed with the connector housing, when the electrical connector fails, the entire electrical connector must be replaced. This not only increases the difficulty of replacing the electrical connector but also further increases the maintenance cost of the electrical connector, which is not conducive to the promotion of electrical connectors. Utility Model Content

[0003] The main objective of this invention is to provide an easily detachable electrical connector. By providing wire clamping covers at both ends of the connector housing, each cover can be detachably installed at the opening of the corresponding power inlet slot after being pressed against the corresponding power inlet cable. This allows the power inlet cable to be detachably installed at both ends of the connector housing. This overcomes the shortcomings of traditional electrical connectors where the connector housing and power inlet cable are integrally formed. When any component of the connector housing, control circuit board, or power inlet cable is damaged, it can be replaced individually and promptly, avoiding the need for complete replacement when any component is damaged. This not only reduces the difficulty and cost of maintaining the electrical connector but also promotes its widespread adoption.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A detachable electrical connector includes: a connector housing, a control circuit board, and power cables. The control circuit board is installed inside the connector housing. The connector housing has cable entry slots at both ends. The power cables enter the connector housing from the cable entry slots at both ends and are electrically connected to the two ends of the control circuit board. The connector also includes two wire clamping covers at both ends of the connector housing. Each wire clamping cover is pressed against the corresponding power cable and can be detachably installed at the opening of the corresponding cable entry slot, pressing the power cable against the inner wall of the slot, thereby allowing the power cable to be detachably installed at both ends of the connector housing.

[0006] As a preferred embodiment of an easily detachable electrical connector, the free end of the wire insertion slot extends outward to form a fixed abutment plate, the fixed abutment plate extends to both sides to form fixed blocks, and the two sides of one end of the wire clamping cover extend toward the fixed blocks to form elastic fixed hooks, which are detachably engaged with the fixed blocks.

[0007] As a preferred embodiment of the detachable electrical connector, the inner wall of the wire clamp cover has two corners on the side away from the elastic fixing hook, and the inner walls of the two fixing blocks have second limiting arc surfaces. After the power cable is clamped between the wire clamp cover and the fixing abutment plate, the first limiting arc surfaces and the second limiting arc surfaces abut against both sides of the power cable.

[0008] As a preferred embodiment of an easily detachable electrical connector, the two sides of the inner wall of the connector housing extend inward to form a first limiting protrusion, and the two sides of the other end of the wire clamping cover extend toward the inner wall of the connector housing to form an anti-disengagement protrusion, the anti-disengagement protrusion abutting against the first limiting protrusion.

[0009] As a preferred embodiment of an electrical connector that is easy to disassemble, the inner walls of the connector housing extend inward on both sides to form a second limiting protrusion. The second limiting protrusion is spaced apart from one end of the first limiting protrusion to form a positioning groove. The middle part of the wire clamping cover extends outward to form a positioning protrusion, which engages with the positioning groove.

[0010] As a preferred embodiment of an electrical connector that is easy to disassemble, the wire clamping cover protrudes outward from the side away from the connector housing to form a fixing protrusion, and a fixing hole is provided on the fixing protrusion.

[0011] As a preferred embodiment of the easily detachable electrical connector, the easily detachable electrical connector further includes: a power supply cable and a cable fixing plate. The power supply cable is connected to the outward-facing side of the control circuit board, and the cable fixing plate is provided with a cable bundling hole. The mounting side of the connector housing is provided with a fixing plate opening, and the cable fixing plate is installed at the fixing plate opening. After the control circuit board is fixed inside the connector housing, the power supply cable connected to the control circuit board passes through the cable bundling hole and extends to the outside.

[0012] As a preferred embodiment of the easily detachable electrical connector, the cable fixing plate extends outward from the position of the cable hole to form a cable positioning cylinder. The power cable passes through the cable hole and extends outward through the cable positioning cylinder. The cable positioning cylinder is used to gather the power cable and position the easily detachable electrical connector during installation.

[0013] As a preferred embodiment of an easily detachable electrical connector, the fixing plate has positioning grooves on both sides of the opening, and the two sides of the wire harness fixing plate are embedded in the positioning grooves; the bottom of the inner wall of the connector housing has a first abutting protrusion, and the bottom of the wire harness fixing plate has a second abutting protrusion, the second abutting protrusion pressing the control circuit board against the first abutting protrusion.

[0014] As a preferred embodiment of an electrical connector that is easy to disassemble, the connector housing has two pick-and-place protrusions on the side away from where the power cord is installed. The two pick-and-place protrusions are arranged sequentially along the length of the connector housing and are both perpendicular to the length of the connector housing.

[0015] The beneficial effects of this utility model are:

[0016] This invention proposes a conveniently disassembled electrical connector, comprising: a connector housing, a control circuit board, and a power supply cable. The control circuit board is installed inside the connector housing. The connector housing has cable entry slots at both ends. The power supply cable enters the connector housing from the cable entry slots at both ends and is electrically connected to both ends of the control circuit board. By providing wire clamping covers at both ends of the connector housing, each clamping cover can be detachably installed at the opening of the corresponding cable entry slot after pressing onto the corresponding power supply cable, thus pressing the power supply cable against the inner wall of the slot and allowing the power supply cable to be detachably installed at both ends of the connector housing. This design overcomes the shortcomings of traditional electrical connectors where the connector housing and power supply cable are integrally formed. When any component of the electrical connector—the connector housing, control circuit board, or power supply cable—is damaged, it can be replaced individually and promptly, avoiding the need for complete replacement when any component is damaged. This not only reduces the maintenance difficulty of the electrical connector but also further reduces its maintenance cost, facilitating the widespread adoption of electrical connectors.

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] In existing technology, a typical electrical connector includes: a connector housing, a control circuit board installed inside the connector housing, and power input lines integrally formed with the connector housing at both ends. The power input lines are electrically connected to the control circuit board, and the power input lines extending from the control circuit board extend into the lamp and are electrically connected to the light source of the lamp. Thus, the electrical connector supplies power to the lamp and can also connect two adjacent lamps. However, since the power input lines are integrally formed with the connector housing, when the electrical connector fails, the entire electrical connector must be replaced. This not only increases the difficulty of replacing the electrical connector but also further increases the maintenance cost of the electrical connector, which is not conducive to the promotion of electrical connectors.

[0026] like Figure 1 and Figure 2As shown, Embodiment 1 of this utility model provides an easily detachable electrical connector, which includes: a connector housing 10, a control circuit board 20, an input power line 30, an output power line 40, and a cable fixing plate 50. The control circuit board 20 is installed inside the connector housing 10. The connector housing 10 has input slots 11 at both ends. The input power lines 30 are connected to the connector housing 10 from the input slots 11 at both ends of the connector housing 10 and are electrically connected to the two ends of the control circuit board 20. After the cable fixing plate 50 is installed in the connector housing 10, the output power lines 40 of the control circuit board 20 extend to the outside through the cable fixing plate 50.

[0027] The device also includes two wire clamping covers 60 respectively located at both ends of the connector housing 10. Each wire clamping cover 60 is clamped onto the corresponding power cable 30 and can be detachably installed at the opening of the corresponding cable inlet groove 11, pressing the power cable 30 against the inner wall of the cable inlet groove 11, thereby making the power cable 30 detachably installed at both ends of the connector housing 10.

[0028] In this utility model, the above-described method overcomes the disadvantage of the traditional electrical connector where the connector housing 10 and the power supply line 30 are integrally formed. When any component of the electrical connector, such as the connector housing 10, the control circuit board 20, or the power supply line 30, is damaged, it can be replaced individually and promptly, avoiding the need to replace the entire connector when the above components are damaged. This not only reduces the maintenance difficulty of the electrical connector but also further reduces the maintenance cost, which is conducive to the promotion of the electrical connector.

[0029] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in order to install the wire clamping cover 60, the free end of the wire inlet groove 11 extends outward to form a fixed abutment plate 111, the fixed abutment plate 111 extends to both sides to form a fixed locking block 112, and the two sides of one end of the wire clamping cover 60 extend toward the fixed locking block 112 to form an elastic fixing hook 61. The elastic fixing hook 61 is detachably locked to the fixed locking block 112, thereby detachably installing the wire clamping cover 60 to both ends of the connector housing 10.

[0030] To prevent damage to the power cable 30, the inner wall of the wire clamping cover 60 has two corners on the side away from the elastic fixing hook 61, and the inner walls of the two fixing blocks 112 have second limiting arc surfaces 113. After the power cable 30 is clamped between the wire clamping cover 60 and the fixing abutment plate 111, the first limiting arc surface 62 and the second limiting arc surface 113 abut against both sides of the power cable 30, thereby preventing the power cable 30 from being scratched by the connector housing 10 and the wire clamping cover 60.

[0031] To prevent the wire clamping cover 60 from detaching from the connector housing 10, the two sides of the inner wall of the connector housing 10 extend inward to form a first limiting protrusion 12, and the two sides of the other end of the wire clamping cover 60 extend toward the inner wall of the connector housing 10 to form an anti-detachment protrusion 63. The anti-detachment protrusion 63 abuts against the first limiting protrusion 12, thereby preventing the wire clamping cover 60 from detaching from the connector housing 10 through the abutment of the anti-detachment protrusion 63.

[0032] To position the wire clamping cover 60 for installation, the inner walls of the connector housing 10 extend inward to form second limiting protrusions 13. The second limiting protrusions 13 form positioning grooves 14 at a distance from one end of the first limiting protrusions 12. The middle part of the wire clamping cover 60 extends outward to form positioning protrusions 64. The positioning protrusions 64 engage with the positioning grooves 14, thereby positioning and installing the wire clamping cover 60 at both ends of the connector housing 10.

[0033] In order to install the easily detachable electrical connector, the wire clamping cover 60 protrudes outward on the side away from the connector housing 10 to form a fixing protrusion 65. A fixing hole 651 is provided on the fixing protrusion 65. After the fixing screw passes through the lamp that needs to install the easily detachable electrical connector, it extends into the fixing hole 651 for fixing, thereby installing the easily detachable electrical connector on the lamp.

[0034] To install the power cable 40 and the cable fixing plate 50, the power cable 40 is connected to the outward side of the control circuit board 20, and the cable fixing plate 50 is provided with a cable hole 51; the mounting side of the connector housing 10 is provided with a fixing plate opening 15, and the cable fixing plate 50 is installed at the fixing plate opening 15. After the control circuit board 20 is fixed inside the connector housing 10, the power cable 40 connected to the control circuit board 20 passes through the cable hole 51 and extends to the outside.

[0035] To facilitate the positioning and installation of the power cable 40 and the easily detachable electrical connector, the cable fixing plate 50 extends outward from the cable hole 51 to form a cable positioning cylinder 52. After the power cable 40 passes through the cable hole 51, it extends outward through the cable positioning cylinder 52. When the cable positioning cylinder 52 passes through the inlet hole of the lamp, the mounting hole of the lamp is aligned with the fixing hole 651 on the fixing protrusion 65. Thus, the cable positioning cylinder 52 is used to gather the power cable 40 and position the easily detachable electrical connector for installation.

[0036] To install the cable tie fixing plate 50, positioning grooves 151 are provided on both sides of the opening 15 of the fixing plate, and the two sides of the cable tie fixing plate 50 are embedded in the positioning grooves 151; a first abutting protrusion 16 is provided at the bottom of the inner wall of the connector housing 10, and a second abutting protrusion 53 is provided at the bottom of the cable tie fixing plate 50. After the easily detachable electrical connector is installed on the lamp, the lamp abuts against the cable tie fixing plate 50, and then the second abutting protrusion 53 of the cable tie fixing plate 50 presses the control circuit board 20 against the first abutting protrusion 16.

[0037] To facilitate the removal and placement of the easily detachable electrical connector, the connector housing 10 is provided with two pick-and-place protrusions 17 on the side away from where the power cord 30 is installed. The two pick-and-place protrusions 17 are arranged sequentially along the length direction of the connector housing 10 and are both perpendicular to the length direction of the connector housing 10. In the removal method, the user can easily pick up and put down the easily replaceable power cord electrical connector by picking up the two pick-and-place protrusions 17 with two fingers.

[0038] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this invention, and these variations still fall within the protection scope of this utility model.
