Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a front-mounted wire-end connector that is easy to assemble and disassemble. Background Technology

[0002] Traditional wire-end connectors typically employ plug-in or crimp-type structures. Their snap-fit, locking mechanisms, and terminal layouts are only compatible with insertion from the back of the panel. During use, the pins are inserted from the front of the panel to connect with the wire-end connector. However, this back-end assembly method complicates the sealing design between the connector and the panel. Furthermore, with increasing equipment integration and increasingly compact internal spaces, back-end assembly requires a larger installation space, limiting the miniaturization and integration of electrical equipment and failing to meet the modern trend towards thinner, lighter, and more integrated devices. In addition, assembling wire-end connectors from the back involves disassembling other components to expose the mounting surface, resulting in a cumbersome installation process and requiring repeated disassembly and reassembly for maintenance. Moreover, operators cannot visually confirm the connector's installation status and wiring accuracy, increasing the risk of electrical faults and affecting equipment reliability and safety. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a front-mounted wire connector that is easy to install and remove. The wire connector can be installed and removed along the front of the mechanism panel and is easy to disassemble and replace.

[0007] One end of the spring arm is connected to the second plug-in portion, and the other end extends toward the first plug-in portion; the end of the spring arm near the first plug-in portion is provided with a fastening portion protruding toward the side away from the connector body, for fastening connection with the mechanism panel.

[0008] Furthermore, the housing is also provided with a protective boss, which is located on the outer wall of the first insertion part and protrudes in the same direction as the fastening part; the movable end of the spring arm is located within the deformation space formed by the protective boss and the connector body.

[0009] Furthermore, the inner wall of the insertion cavity is provided with a positioning block; the protective boss is provided with a first positioning groove, and the positioning block is engaged in the first positioning groove.

[0010] Furthermore, the protrusion height of the protective boss is greater than or equal to the protrusion height of the fastening part, so that when the elastic arm deforms elastically, the fastening part can be completely embedded in the deformation space.

[0011] Furthermore, the connector body is also provided with a guide groove, which is formed by cutting from the first insertion part toward the second insertion part.

[0012] Furthermore, the spring arm is also provided with a pressing part, one end of which is connected to the second insertion part and the other end is connected to the fastening part; the pressing part is at least partially exposed on the mechanism panel and is located on one side of the front of the mechanism panel.

[0033] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Traditional wire-end connectors typically employ plug-in or crimp-type structures, with their snap-fit, locking mechanisms, and terminal layouts only suitable for insertion from the back of the mechanism panel. However, this back-mounting method complicates the sealing structure design between the connector and the mechanism panel; furthermore, with the pins inserting into the connector from the front, a large installation space needs to be reserved on both sides of the mechanism panel, limiting the miniaturization and integration of electrical equipment and failing to meet the modern trend towards thinner, lighter, and more integrated devices.

[0035] Based on this, please refer to Figure 1-6 This application provides a front-mounted wire connector 100 that is easy to assemble and disassemble, which is assembled with the front of the mechanism panel 200. The connector includes a housing, which includes a connector body 10 and spring arms 20 disposed on one or both sides of the connector body 10.

[0036] Specifically, the connector body 10 includes a first insertion portion 11 and a second insertion portion 12 located at both ends in the insertion direction; the mechanism panel 200 has an insertion cavity 201, and the first insertion portion 11 is inserted into the insertion cavity 201. One end of the spring arm 20 is connected to the second insertion portion 12 and extends toward the first insertion portion 11; the end of the spring arm 20 near the first insertion portion 11 is provided with a fastening portion 22 protruding toward the side away from the connector body 10, for fastening connection with the mechanism panel 200.

[0037] The easy-to-assemble and disassemble front-mounted wire connector 100 provided in this application embodiment can be assembled along the front of the mechanism panel 200 and is easy to disassemble and replace. It can simplify the structure and space design of the back of the mechanism panel 200 and is conducive to the miniaturization and integration design of electrical equipment.

[0038] Furthermore, in some embodiments, the side wall of the insertion cavity 201 is provided with a slot 202, and the spring arm 20 elastically abuts against the slot 202. During the assembly process, the spring arm 20 is slidably inserted into the insertion cavity 201 along the slot 202 until the fastening part 22 is fastened to the mechanism panel 200.

[0039] Please see Figure 3 Furthermore, in some embodiments, the spring arm 20 is also provided with a pressing part 21 for easy hand-pressing. One end of the pressing part 21 is connected to the second insertion part 12, and the other end is connected to the fastening part 22; the pressing part 21 is at least partially exposed outside the mechanism panel 200 and is located on one side of the front of the mechanism panel 200. When disassembling the wire connector 100, pressing the pressing part 21 causes the pressing part 21 to move the fastening part 22 at its end, disengaging it from the mechanism panel 200.

[0040] Please see Figure 3 Furthermore, in some embodiments, the housing is also provided with a protective boss 13 to prevent the spring arm 20 from breaking or being damaged due to improper insertion between the wire connector 100 and the inner wall of the insertion cavity 201 during the insertion of the wire connector 100 into the insertion cavity 201, thus affecting the stability of the insertion of the wire connector 100 and the mechanism panel 200. Specifically, the protective boss 13 is provided on the outer wall of the first insertion part 11 and protrudes in the same direction as the fastening part 22. The protective boss 13 and the outer wall of the connector body 10 form a deformation space, and the movable end of the spring arm 20 is movably disposed in the deformation space, deforming within the deformation space to fasten or disengage with the mechanism panel 200. When assembling the wire connector 100, the fastening part 22 is squeezed and deflected toward the inner side of the deformation space, and slides along the slot 202 until it fastens with the mechanism panel 200. When disassembling the wire connector 100, pressing the pressing part 21 will also cause the fastening part 22 to deflect toward the inside of the deformation space, so that the fastening part 22 is disengaged from the mechanism panel 200.

[0041] Furthermore, in some embodiments, the protruding height of the protective boss 13 is greater than or equal to the height of the fastening part 22. With this arrangement, when the spring arm 20 elastically deforms, the fastening part 22 can be completely embedded within the deformation space, thus better protecting the integrity of the fastening part 22. With this arrangement, when disassembling the wire connector 100, pressing the pressing part 21 provides sufficient displacement space for the fastening part 22 to disengage from the mechanism panel 200. It is understood that in its natural state, the fastening part 22 protrudes from the protective boss 13 and elastically abuts against the slot 202, which facilitates a stable fastening between the fastening part 22 and the mechanism panel 200.

[0042] Furthermore, in some embodiments, the inner wall of the insertion cavity 201 is provided with a positioning block for positioning the wire connector 100 against the protective boss 13 when it is inserted into the mechanism panel 200. Furthermore, the protective boss 13 is provided with a first positioning groove 131, and the positioning block is engaged within the first positioning groove 131, which further assists in the positioning of the wire connector 100 and the mechanism panel 200, and prevents the connector body 10 from shaking within the insertion cavity 201.

[0043] Please see Figure 3 Furthermore, in some embodiments, the connector body 10 is also provided with a guide groove 14, which is formed by cutting from the first insertion part 11 toward the second insertion part 12; the insertion cavity 201 is provided with a guide block, which is slidably connected to the guide groove 14 to prevent the wire end connector 100 from being inserted in reverse.

[0044] Please see Figure 3 and Figure 6 Furthermore, in some embodiments, the easy-to-disassemble upright wire connector 100 also includes a terminal block 30, and the connector body 10 is provided with a guide hole 15 that passes through the first insertion portion 11 and the second insertion portion 12; the terminal block 30 is fixedly inserted into the guide hole 15 through one end of the first insertion portion 11.

[0045] Furthermore, in some embodiments, the inner wall of the guide hole 15 is provided with a latch 151, and the terminal 30 is provided with a limiting spring 31. The limiting spring 31 is fastened to the latch 151 to improve the holding force of the connector body 10 on the terminal 30 and prevent the wire of the terminal 30 from being pulled out from the guide hole 15.

[0046] Please see Figure 5 Furthermore, in some embodiments, a safety wall 16 is provided on the outside of the connector body 10. The safety wall 16 extends protrudingly along the outer periphery of the second insertion portion 12, and the pressing portion 21 is connected to the safety wall 16. Specifically, the thickness of the safety wall 16 is greater than the thickness of the pressing portion 21, so that the pressing portion 21 is spaced a certain distance from the outer wall of the terminal and the second insertion portion 12.

[0047] Furthermore, in some embodiments, the safety wall 16 is extended a certain distance toward the end away from the first plug portion 11, so that one end face of the guide hole 15 is recessed into the safety wall 16. This can increase the electrical clearance between the terminal block 30 or the pin and the mechanism panel 200, thereby improving the electrical performance of the wire connector 100.

[0048] Please see Figure 1-6 The assembly process of the easily detachable front-mounted wire connector 100 provided in this embodiment is as follows: First, insert the terminal block 30 into the guide hole 15 from one end of the first insertion part 11. Then, insert the wire connector 100 with the terminal block 30 into the insertion cavity 201 from the front of the mechanism panel 200 until the spring arm 20 is engaged with the mechanism panel 200. During use, simply insert the mating part with the pins into the guide hole 15 from one end of the second insertion part 12 to achieve connector engagement. In this configuration, all assembly is done from the front of the mechanism panel 200, simplifying the structure and space on the back of the mechanism panel 200, which is beneficial for miniaturization and integrated design. When disassembling the wire connector 100, simply press the spring arm 20 to disengage the locking part 22 from the mechanism panel 200, and then pull the wire connector 100 out from the front of the mechanism panel 200. The overall disassembly and assembly method is simple and easy to operate.

[0049] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0050] (1) The wire end connector can be installed and removed along the front of the mechanism panel, which can simplify the structure and space design of the back of the mechanism panel and is conducive to the miniaturization and integration of electrical equipment.

[0051] (2) By setting a pressable spring arm, it is easy to disassemble and replace the wire end connector;

[0052] (3) By setting a safety wall that extends a certain distance toward the end away from the first plug, one end face of the guide hole is recessed into the safety wall, which can increase the electrical clearance between the terminal block or pin and the mechanism panel and improve the electrical performance of the connector.

[0053] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
