[0032] The utility model discloses a connector, such as Figures 1 to 12As shown, it comprises a wire assembly 1, a base 2 and a first end cover 3, wherein the wire assembly 1 is a terminal, and a locking groove 11 is also provided on the wire assembly 1.

[0033] The base 2 is provided with a first wire hole 21, a first elastic protrusion 22 and a first locking structure 23, wherein the first wire hole 21 is used to penetrate the wire assembly 1, and the number of the first wire holes 21 corresponds to the number of the wire assemblies 1; the first elastic protrusion 22 is arranged on the side of the first wire hole 21 for being inserted into the locking groove 11; the first locking structure 23 is used to fix the first end cover 3.

[0034] The first end cover 3 is provided with a second wire hole 31, a second elastic protrusion 32, a limiting plate 34, two locking structures 33 and a disassembly hole 35, wherein the position of the second wire hole 31 corresponds to the position of the first wire hole 21, that is, the axes of the corresponding second wire hole 31 and the first wire hole 21 are located on the same straight line; the second elastic protrusion 32 is arranged on the side of the second wire hole 31, for being inserted into the locking groove 11 and being staggered with the position of the first elastic protrusion 22, that is, realizing secondary locking of the wire assembly 1; the second locking structure 33 cooperates with the first locking structure 23 to fix the first end cover 3 on the base 2; after the base 2 and the first end cover 3 are installed, the limiting plate 34 is placed on one side of the first elastic protrusion 22 to realize the movement limitation of the first elastic protrusion 22 with the first elastic protrusion 22; the disassembly hole 35 is arranged on the outer wall to facilitate the removal of the first end cover 3.

[0035] By adopting the above connector structure, the first elastic protrusion 22 and the second elastic protrusion 32 are respectively arranged on the base 2 and the first end cover 3 to respectively realize the first locking and the second locking of the line assembly 1, thereby enhancing the stability of the fixing of the line assembly 1 and improving its tensile strength. Since the first elastic protrusion 22 and the second elastic protrusion 32 are elastic parts, they are easy to install. However, when the pulling force exceeds a certain magnitude, they will also deform, causing the first elastic protrusion 22 and the second elastic protrusion 32 to be separated from the locking groove 11. In this regard, by arranging a limit plate 34 on the first end cover 3, after the base 2 and the first end cover 3 are installed, the deformation resistance of the first elastic protrusion 22 is enhanced, and the stability of the fixing of the line assembly 1 is further enhanced, and its tensile strength is improved.

[0036] The first elastic protrusion 22 and the second elastic protrusion 32 both include a connecting piece and a protrusion structure arranged on the connecting piece. The connecting piece is used to connect and fix the protrusion, so as to adjust the position of the protrusion structure and realize the rapid installation of the first end cover, the wire assembly and the base.

[0037] In order to further enhance the deformation limiting function of the first elastic protrusion 22, the cross-sections of the connecting piece and the limiting piece 34 are both arc-shaped. The arc-shaped piece is directly attached to the outside of the first elastic protrusion 22; or, the distance between the limiting piece 34 and the connecting piece is less than the thickness of the protruding structure in the radial direction of the line component 1, so that even if the connecting piece is deformed, its deformation amount will not cause the protruding structure to be separated from the locking groove 11, so as to achieve reliable locking in the axial direction of the line component.

[0038] The wire assemblies 1 are generally arranged in an array, and the corresponding wire holes are also arranged in an array in the wire assemblies 1 arranged in an array. In order to further enhance the reliability of locking the wire assemblies 1, guide posts 25 are provided at the center of two adjacent rows and columns of wire assemblies 1, and limiting grooves 251 matching the wire assemblies 1 are provided around the guide posts.

[0039] In this regard, the guide column 25 can be arranged on the base 2 or the first end cover 3, that is, the guide column 25 can be arranged at the center of two adjacent rows and columns of first linear holes 21, or at the center of two adjacent rows and columns of second linear holes 31.

[0040] The wire assembly 1 can be a single row with multiple columns, multiple rows with a single column, or multiple rows with multiple columns. Exemplarily, it can be two rows with two columns. Correspondingly, at this time, the first wire hole 21 and the second wire hole 31 are both two rows with two columns. At this time, in order to further enhance the locking stability of the wire assembly, the limit groove 251 on the guide column 25 and the first elastic protrusion 22 are respectively located at the two ends of the diameter of the corresponding first wire hole 21.

[0041] The guide column 25 and the first elastic protrusion 22 are respectively arranged at two ends of the diameter of the line component. The guide column 25 can not only realize the guiding function of the line component installation, but also realize the radial limitation of the first elastic protrusion 22.

[0042] To facilitate disassembly, the disassembly holes 35 can be provided on both sides of the first end cover 3 .

[0043] The first locking structure 23 and the second locking structure 33 cooperate with each other to achieve the fixation of the first end cover 3 and the base 2, and there are many ways to achieve this. For example, Figure 1 As shown, the second locking structure 33 can adopt a structure in which a locking hole is set on the spring sheet. Correspondingly, the first locking structure 23 can adopt a structure in which a protrusion for being clamped in the locking hole is set on the base 2. Its structure is simple and easy to install.

[0044] The first end cap 3 realizes the sealing of one end of the base on the basis of realizing the locking of the wire assembly. In this regard, on the basis of any of the above structures, a second end cap is added to realize the sealing of the other end of the base.

[0045] A third locking structure 24 is provided on the outer wall of the base 2;

[0046] The second end cover 4 is also included, and the second end cover 4 is provided with a third wire hole 41 corresponding to the position of the first wire hole 21, and a fourth locking structure 42 that cooperates with the third locking structure 24 to fix the second end cover 4 on the base 2. The third locking structure 24 and the fourth locking structure 42 can adopt the same structure as the first locking structure 23 and the second locking structure 33, and will not be described in detail here.

[0047] In order to prevent the intrusion of water and dust and ensure the normal operation of the line assembly in a harsh environment, a line sealing body 51 which is sleeved on the line assembly 1 is arranged in the second end cover 4 .

[0048] Furthermore, a sealing ring 51 is provided on the connecting end surface between the base 2 and the first end cover 3 .

[0049] In order to achieve the locking of the connector and the plug end to improve the connection stability, a locking member 6 for locking the base 2 and the plug end is also included. The locking member 6 can be Figure 1 The structure shown in is implemented.

[0050] The locking member 6 includes an operating portion 61, a first elastic locking tongue 62 and a second elastic locking tongue 63 arranged at one end of the operating portion 61, and a stop portion 64 arranged on the operating portion 61 to achieve movement limitation; a mounting portion 26 for mounting the locking member 6 is provided on the base 2, and a pre-mounting hole 261 for clamping the first elastic locking tongue 62 and a locking hole 262 for clamping the first elastic locking tongue 62 after the base and the mating end are inserted into place.

[0051] Correspondingly, a guide slope 71 and a locking groove 72 are provided on the plug-in end 7. Before plug-in, the first elastic locking tongue 62 is stuck in the pre-installed hole 261. After plug-in, the locking member 6 is pushed, and the first elastic locking tongue 62 is deformed under the force, disengages from the pre-installed hole 261 and moves toward the locking hole 262 and is stuck in the locking hole 262. At the same time, the second elastic locking tongue 63 is deformed under the action of the guide slope 71 and moves along the guide slope 71 and then slides into the locking groove 72 to achieve locking of the base and the plug-in end.

[0052] The above structure can not only realize reliable locking of the wire assembly, but also realize reliable locking of the connector and the plug end.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
