Description

Technical Field

[0001] The utility model relates to the technical application field of connectors, in particular to a wire end connector which is convenient to disassemble and a locking piece thereof. Background Art

[0002] The existing wire end connector consists of a sheath body, a locking piece and a plurality of terminal harnesses, wherein the terminal harness is composed of a terminal connected to a harness wire. When the harness terminal needs to be repaired or replaced, a specific tool is required to pry the locking piece at the unlocking hole of the locking piece to unlock the locking piece to a locked state, and then the harness terminal can be removed from the sheath body by a specific tool. This method of unlocking the locking piece is very inconvenient, and the locking piece is easily damaged when prying.

[0003] At the same time, since the locking member structure of the existing wire end connector is usually more complicated, when an external force is applied to the locking member, the locking member is prone to uneven force, which may cause damage to the locking member during the locking or unlocking process.

[0004] Based on the above technical problems, there is an urgent need to provide a wire end connector and a locking member thereof that is easy to disassemble. Utility Model Content

[0005] To solve the above technical problems, the utility model provides a wire end connector and a locking member thereof that are easy to disassemble. The wire end connector and the locking member thereof have a simple structure and do not require tools during the process of locking or unlocking the terminal, thereby improving work efficiency and ensuring the service life of the connector.

[0006] On the one hand, the technical solution of the utility model provides a wire end connector that is easy to disassemble, including a sheath body and a locking member assembled in the sheath body, wherein the locking member includes a substrate and a locking block arranged on the substrate, and buckles are symmetrically arranged on opposite sides of the locking block;

[0007] The sheath body is provided with an installation groove for assembling the locking piece, and the inner walls on both sides of the installation groove are symmetrically provided with locking clamps used in conjunction with the buckle, and the distance between the symmetrically arranged locking clamps is less than the length of the substrate; the number of locking clamps and one of the buckles on each side is two, and the locking clamps and the buckle are clamped with each other to complete the primary locking or secondary locking of the line end connector.

[0008] When the line end connector is in the primary locking state, the locking card table is separated from the base plate to place the terminal;

[0009] When the wire end connector is in the secondary locking state, the locking clamping platform abuts against the substrate to fix the terminal.

[0010] Furthermore, two locking platforms are provided on each side, each consisting of a first platform and a second platform; the buckle is connected to the first platform in the primary locking state, and is connected to the second platform in the secondary locking state.

[0011] Furthermore, the length of the installation groove is equal to the length of the sheath body.

[0012] Furthermore, the length of the substrate is greater than or equal to the length of the sheath body.

[0013] Furthermore, a guide block is provided on one side of the locking member, and a guide groove used in conjunction with the guide block is provided on the inner wall of the mounting groove.

[0014] Furthermore, the main body extension direction of the guide block is perpendicular to the extension direction of the substrate.

[0015] Furthermore, the wire end connector also includes a plurality of wire harnesses assembled with the sheath body, and terminals are crimped on the ends of the wire harnesses.

[0016] Furthermore, the sheath body is provided with a plurality of terminal assembly grooves, which are all connected with the mounting grooves; the locking block is provided with a plurality of terminal holes used in conjunction with the terminal assembly grooves; the terminals pass through the terminal assembly grooves and the terminal holes in sequence and are connected with the sheath body.

[0017] Furthermore, a positioning block is provided on the inner wall of the upper end of the terminal hole, and the positioning block and the inner wall of the upper end of the terminal hole form an obtuse angle.

[0018] On the other hand, the technical solution of the utility model provides a locking member for a wire end connector. The locking member includes a substrate, a locking block arranged on the substrate, and a guide block arranged on one side. The locking block has a first surface, a second surface, two opposite side surfaces, and a bottom surface. The locking block is provided with a plurality of terminal holes penetrating the first surface and the second surface, and buckles are symmetrically provided on both sides of the locking block. The main body of the guide block extends in a direction perpendicular to the extension direction of the substrate and extends toward the bottom surface of the locking block.

[0019] The beneficial technical effects of the utility model are:

[0020] 1. The locking piece has two locking states relative to the sheath body. When the locking piece is in the first locking state relative to the sheath body, the locking piece and the sheath body are only preliminarily connected and not fixed, which is convenient for personnel to put the terminal into the sheath body or take it out of the sheath body;

[0021] When the locking piece is in a secondary locking state relative to the sheath body, the locking piece is clamped and fixed with the sheath body, and the terminal is fixed at the same time. At this time, the terminal cannot be separated from the sheath body.

[0022] 2. The length of the base plate of the locking member is greater than the distance between the two locking clamps symmetrically arranged on the main body of the sheath, that is, the length of the base plate of the locking member is greater than the length of the locking block. This arrangement makes it convenient for personnel to complete the two locking or disassembly of the base plate relative to the main body of the sheath only by fixing the two ends of the base plate by hand, thereby solving the technical problem that the prior art requires specific tools for disassembly.

DETAILED DESCRIPTION

[0031] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0033] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships recorded in the embodiments and shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0034] like Figure 1-Figure 5 As shown, the utility model specifically relates to a wire end connector that is easy to disassemble, including a sheath body 100 and a locking member 200 assembled in the sheath body 100. The locking member 200 includes a substrate 210 and a locking block 220 disposed on the substrate 210, and buckles 221 are symmetrically provided on opposite sides of the locking block 220.

[0035] The sheath body 100 is provided with an installation groove 110 for assembling the locking member 200. The inner walls on both sides of the installation groove 110 are symmetrically provided with locking clamping platforms 120 used in conjunction with the buckle 221. The distance between the symmetrically arranged locking clamping platforms 120 is less than the length of the substrate 210. The number of the locking clamping platforms 120 and the buckle 221 arranged on both sides is two, and the locking clamping platforms 120 and the buckle 221 are mutually engaged to complete the primary locking or secondary locking of the wire end connector.

[0036] like Figure 4 As shown, when the wire end connector is in a primary locking state, the locking clamping platform 120 is separated from the substrate 210 to place the terminal 301;

[0037] like Figure 5 As shown, when the wire end connector is in the secondary locking state, the locking clamping platform 120 abuts against the substrate 210 to fix the terminal 301 .

[0038] It should be noted that, the sheath body 100 is provided with a mounting groove 110 , and the locking member 200 is assembled to the sheath body 100 through the mounting groove 110 , so as to fix the terminal 301 placed in the sheath body 100 .

[0039] like Figure 3-Figure 5As shown, in a specific embodiment of the utility model, two locking platforms 120 are provided on each side of the sheath body 100, each consisting of a first platform 121 and a second platform 122; the buckle 221 is connected to the first platform 121 in the primary locking state, and is connected to the second platform 122 in the secondary locking state.

[0040] like Figure 1-Figure 4 As shown, a buckle 221 is provided on the opposite side of the locking block 220, and a locking clamping platform 120 composed of a first clamping platform 121 and a second clamping platform 122 is provided in the installation groove 110. When the locking member 200 is placed in the installation groove 110 through the locking block 220, the buckle 221 and the first clamping platform 121 are clamped and connected to complete the preliminary connection between the locking member 200 and the sheath body 100; in the absence of external force, the locking member 200 cannot be separated from the sheath body 100. At this time, the personnel can place the terminal 301 in the sheath body 100.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, when the personnel applies downward pressure to the base plate 210 again, the buckle 221 moves downward and disengages from the first clamping platform 121, and is clamped and connected with the second clamping platform 122, thereby completing the locking of the locking member 200 and the sheath body 100. At this time, the terminal 301 is fixed in the sheath body 100 and cannot be separated. At the same time, the bottom of the base plate 210 abuts against the end of the locking clamping platform 120.

[0042] The terminal 301 can be fixed through the above two locking processes.

[0043] Furthermore, when a person needs to remove the terminal 301, since the length of the substrate 210 is greater than the distance between the two locking clamps 120, and the two locking clamps 120 are located in the mounting groove 110, when the substrate 210 abuts against the locking clamps 120, the two ends of the substrate 210 are suspended relative to the locking clamps 120, which is convenient for the person to pinch the two ends of the substrate 210 with his hands. Figure 4 As shown, when a person pinches the two ends of the substrate 210 with their hands and applies an upward external force to it, the buckle 221 moves upward and separates from the second clamping platform 122, and is clamped and connected with the first clamping platform 121. At this time, the locking block 220 releases the fixation of the terminal 301, making it convenient for the person to pull the terminal 301 out of the sheath body 100.

[0044] In the above process, the locking member 200 is subjected to uniform force, so the body of the locking member 200 will not be damaged.

[0045] Compared with the prior art which requires specific tools for disassembly, the disassembly method of the utility model is simpler and the locking structure is also simpler.

[0046] like Figure 1-Figure 3 As shown, the length of the substrate 210 is greater than the length of the locking block 220. After the locking block 220 is assembled in the mounting groove 110, the terminal 301 is fixed, and the substrate 210 is outside, which is convenient for people to pinch and apply external force to the substrate 210 to complete locking or unlocking.

[0047] Preferably, the length of the mounting groove 110 is equal to the length of the sheath body 100 , and the length of the substrate 210 is greater than or equal to the length of the sheath body 100 .

[0048] Such a configuration can ensure that both ends of the substrate 210 are in a suspended state, making it convenient for personnel to pinch both ends of the substrate 210 to apply external force to the substrate 210, thereby avoiding surface damage to the substrate 210 caused by disassembling the substrate 210 with specific tools.

[0049] like Figure 1-Figure 3 As shown, a guide block 230 is provided on one side of the locking member 200 , and a guide groove 130 used in conjunction with the guide block 230 is provided on the inner wall of the mounting groove 110 .

[0050] The main body extension direction of the guide block 230 is perpendicular to the extension direction of the substrate 210 .

[0051] The provision of the guide block 230 not only plays a fool-proof role, but also ensures the smoothness of the assembly of the locking block 220 in the mounting groove 110 .

[0052] The wire end connector of the present invention further comprises a plurality of wire harnesses 300 assembled with the sheath body 100 , and terminals 301 are crimped at the ends of the wire harnesses 300 .

[0053] The sheath body 100 is provided with a plurality of terminal assembly grooves 140, and the terminal assembly grooves 140 are all connected with the mounting grooves 110; the locking block 220 is provided with a plurality of terminal holes 222 used in conjunction with the terminal assembly grooves 140; the terminals 301 pass through the terminal assembly grooves 140 and the terminal holes 222 in sequence and are connected to the sheath body 100.

[0054] like Figure 3-Figure 5 As shown, the terminal assembly groove 140 and the terminal hole 222 cooperate with each other and are mainly used to separate multiple terminals 301, which not only ensures the appearance but also avoids poor contact of the terminals 301 during use after assembly.

[0055] A positioning block 223 is disposed on the inner wall of the upper end of the terminal hole 222 , and the positioning block 223 forms an obtuse angle with the inner wall of the upper end of the terminal hole 222 .

[0056] After the locking member 200 completes the secondary locking relative to the shield body 100 , the bottom of the positioning block 223 abuts against the surface of the terminal 301 to fix the terminal 301 , thus playing a role of limiting and fixing.

[0057] The bottom of the locking block 220 is provided with a plurality of crimping grooves 240, each of which is provided with a positioning block 223, and the positioning block 223 forms an obtuse angle with the upper plane of the crimping groove 240. The crimping groove 240 is located below the terminal hole 222 and is staggered with the terminal hole 222.

[0058] The principle of fixing the terminals 301 is the same as above and will not be described again. Such a configuration is suitable for the case where there are many terminals 301, so as to divide the multiple terminals 301 into two groups, upper and lower, to avoid interference between the two groups of terminals 301.

[0059] Preferably, the locking member 200 is an integrally formed structure.

[0060] The utility model further provides a locking member 200 for a wire end connector. The locking member 200 includes a substrate 210, a locking block 220 disposed on the substrate 210, and a guide block 230 disposed on one side. The locking block 220 has a first surface, a second surface, two opposite side surfaces, and a bottom surface. The locking block 220 is provided with a plurality of terminal holes 222 penetrating the first surface and the second surface, and buckles 221 are provided on both sides of the locking block 220. The main body of the guide block 230 extends in a direction perpendicular to the extension direction of the substrate 210 and extends toward the bottom surface of the locking block 220.

[0061] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the present invention, and should all be covered within the protection scope of the present invention.
