Description

Technical Field

[0001] The utility model relates to the technical field of cable assembly processing, in particular to a rectangular connector tail injection molding reinforcement structure and a rectangular connector. Background Art

[0002] Finished cables are widely used in medical machinery, communication telephones, intercoms, small terminals, satellite calls and other fields, and their molding process is gradually gaining attention. Rectangular connectors are a type of connector that is basically rectangular in shape and has a basically rectangular mating surface. They are also an important category in the connector family, with many varieties and specifications and a wide range of applications. Rectangular connectors are widely used in communications, industry, aerospace and other fields.

[0003] At present, some rectangular connectors lack the clamping function due to structural limitations, which makes it easy for the welding pressure point to be stressed during use. In particular, when the cable diameter is larger than the thickness of the connector, it is difficult to clamp the wire harness in the center. In addition, due to the structural limitations of the connector, the injection molding parting surface can usually only be selected at the tail of the connector. In subsequent use, the joint surface between the injection molding body and the connector is easy to separate. Utility Model Content

[0004] Based on the problem pointed out in the background technology that the existing rectangular connector wire harness is difficult to clamp and center, the purpose of this application is to propose a rectangular connector tail injection molding reinforcement structure and a rectangular connector. The rectangular connector tail injection molding reinforcement structure can not only clamp the wire harness in the center, but also play a reinforcement role during tail injection molding.

[0005] The utility model is realized by the following technical solutions:

[0006] In the first aspect, the present application provides a rectangular connector tail injection molding reinforcement structure, including a support plate connected to the connector tail cover, one end of the support plate is connected to the connector tail cover, and the other end is connected to a wire clamp, the wire clamp includes an upper wire clamp and a lower wire clamp, both the upper wire clamp and the lower wire clamp are provided with an arc-shaped groove, and the size of the arc-shaped groove of the upper wire clamp and the lower wire clamp is asymmetrical; a U-shaped notch is provided in the middle of the support plate.

[0007] As a better implementation of the present application, the upper wire clamp and the lower wire clamp are fixed to the support sheet via a detachable connector.

[0008] As a better embodiment of the present application, the detachable connecting member includes bolt holes arranged on the support plate, the upper wire clamp and the lower wire clamp, and the upper wire clamp and the lower wire clamp are fixed to the support plate by aligning the bolt holes on the support plate, the upper wire clamp and the lower wire clamp and then installing locking bolts.

[0009] As a preferred implementation of the present application, the depth of the arc-shaped groove on the upper wire clamp is greater than the depth of the arc-shaped groove on the lower wire clamp.

[0010] As a better implementation of the present application, the support sheet is a trapezoidal structure, and the width of the support sheet connected to the connector tail cover end is greater than the width of the support sheet connected to the wire clamp end.

[0011] As a better implementation of the present application, a connector original wire clamp is installed on the connector rear cover, and the support sheet is installed between the connector rear cover and the connector original wire clamp.

[0012] As a better implementation of the present application, the width of the support sheet is designed according to the width of the wire outlet of the connector rear cover; the thickness of the support sheet is equal to the gap height between the original wire clamp of the connector and the connector rear cover.

[0013] As a preferred embodiment of the present application, after the support sheet is inserted into the gap between the connector original wire clamp and the connector rear cover, the support sheet is fixed in the connector rear cover by a locking structure.

[0014] As a better implementation of the present application, the locking structure includes a screw hole provided on the original wire clamp of the connector, and the support plate is fixed by installing a countersunk screw in the screw hole.

[0015] Among them, the support sheet has a hole at the head, and the hole spacing is the same as the hole spacing of the two threaded holes of the original connector wire clamp. The support sheet extends into the connector rear cover, and is locked between the rear cover and the original connector wire clamp through the countersunk screws and wire clamps originally provided with the connector to achieve the reinforcement function. When external force is applied between the injection molded body and the connector, the support sheet bears the force.

[0016] In a second aspect, the present application provides a rectangular connector, comprising a tail injection molding reinforcement structure according to any one of the above-mentioned embodiments.

[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0018] (1) The tail injection reinforcement structure of the rectangular connector in the present application is provided by adding a support sheet and two wire clamps, and the two wire clamps are asymmetrical structures. The two asymmetrical wire clamps are fixed at the tail end of the support sheet, which can clamp the wire harness and center the wire harness;

[0019] (2) The injection-molded reinforcement structure at the rear of the rectangular connector in the present application can be used to fix cables outside the rear cover whose diameter is greater than the thickness of the rear cover and cannot enter the rear cover;

[0020] (3) The support sheet in the present application is a whole, the fixed position is more accurate, and it will not shake at will. There is no need to adjust the centering during installation, and it can be installed directly;

[0021] (4) The U-shaped notch provided on the support plate of the present application allows the unstripped portion of the cable to be installed in the U-shaped notch, which will not affect the centering of the wire harness. At the same time, because the thickness distribution of the tail cover itself at the outlet is not centered, after the support plate is installed, if a symmetrical wire clamp is designed, the cable will not be centered after clamping, and the height of the wire clamp protruding from the two sides of the tail cover will also be different, which will affect the subsequent pouring and injection molding. The present application is designed to have an asymmetrical wire clamp on both sides, so that the wire harness is centered and the thickness of the highest point of the wire clamp protruding from both ends of the tail cover is the same. The subsequent pouring and injection molding can be designed into a symmetrical structure on both sides, which is beautiful in structure and can also save design costs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1

[0034] like Figures 1 to 4 As shown, this embodiment provides a rectangular connector tail injection molding reinforcement structure, including a support sheet 04 connected to the connector tail cover 07, one end of the support sheet 04 is connected to the connector tail cover 07, and the other end is connected to a wire clamp, the wire clamp includes an upper wire clamp 01 and a lower wire clamp 02, both the upper wire clamp 01 and the lower wire clamp 02 are provided with an arc groove, and the size of the arc groove of the upper wire clamp 01 and the lower wire clamp 02 is asymmetrical; a U-shaped notch 09 is provided in the middle of the support sheet 04.

[0035] A protective pad is installed in the arc-shaped groove to reduce the friction between the cable 08 and the upper wire clamp 01 and the lower wire clamp 02.

[0036] Specifically, in order to improve the convenience of installation and disassembly of the reinforcement structure, the upper wire clamp 01 and the lower wire clamp 02 are fixed to the support sheet 04 by a bolt assembly. The specific fixing structure is: bolt holes are set on the support sheet 04, the upper wire clamp 01, and the lower wire clamp 02. When installing, after aligning the bolt holes on the support sheet 04, the upper wire clamp 01, and the lower wire clamp 02, insert the locking bolt 03 into the bolt hole, and then use the locking nut to lock and fix it, so that the upper wire clamp 01 and the lower wire clamp 02 can be fixed on the support sheet 04. This structure is not only convenient to install and has a good fixing effect, but also very convenient when alignment is required for disassembly.

[0037] Specifically, in order to further improve the centering stability of the cable 08 harness after installation, the depth of the arc-shaped groove on the upper wire clamp 01 is set to be greater than the depth of the arc-shaped groove on the lower wire clamp 02.

[0038] Specifically, the support piece 04 is a trapezoidal structure, and the width of the connection between the support piece 04 and the connector tail cover 07 is greater than the width of the connection between the wire clamp end.

[0039] Specifically, the connector rear cover 07 is installed with the connector original wire clamp 06, and the support sheet 04 is installed between the connector rear cover 07 and the connector original wire clamp 06. The width of the support sheet 04 is designed according to the width of the wire outlet of the connector rear cover 07; the thickness of the support sheet 04 is equal to the height of the gap between the connector original wire clamp 06 and the connector rear cover 07. After the support sheet 04 is inserted between the connector rear cover 07 and the connector original wire clamp 06, the support sheet 04 is fixed in the connector rear cover 07 by a locking structure. The locking structure includes a screw hole set on the connector original wire clamp 06, and the support sheet 04 is fixed by installing a countersunk screw 05 in the screw hole.

[0040] The rectangular connector tail injection molding reinforcement structure in this embodiment is achieved by adding a support sheet 04 and two wire clips. The thickness of the support sheet 04 is designed to be just the distance from the surface of the connector original wire clip 06 to the surface of the connector tail cover 07 after the connector original wire clip 06 is installed. After the support sheet 04 is installed, the surface of the connector original wire clip 06 is flush with the plane of the connector tail cover 07, avoiding the trouble caused by the connector original wire clip 06 being higher than the plane of the connector tail cover 07 in subsequent use. The support sheet 04 has a hole at the head, and the hole spacing is the same as the hole spacing of the two threaded holes of the connector original wire clip. The support sheet 04 extends into the connector tail cover 07, and the support sheet 04 is locked between the connector tail cover 07 and the connector original wire clip 06 by the countersunk screw 05 and the connector original wire clip 06, so as to realize the reinforcement function. When the injection molding body and the connector are subjected to external force, the support sheet 04 bears the force. Two asymmetric upper wire clamps 01 and lower wire clamps 02 are fixed at the rear end of the support plate 04 to clamp the wire harness and center the wire harness, thereby fixing the cable 08 outside the connector rear cover 07, whose diameter is greater than the thickness of the rear cover and cannot enter the rear cover.

[0041] In addition, the support sheet 04 in this embodiment is designed as a whole, the fixed position is more accurate, and it will not shake at will. There is no need to adjust the centering during installation, and it can be installed directly. At the same time, a U-shaped notch 09 is set on the support sheet 04, and the unpeeled part of the cable 08 is installed in the U-shaped notch 09, which will not affect the centering of the wire harness. At the same time, because the thickness distribution of the connector tail cover 07 itself at the outlet is not centered, after installing the support sheet 04, if a symmetrical wire clamp is designed on both sides, the cable 08 will not be centered after clamping, and the height of the wire clamp protruding from the thickness of the tail cover on both sides will also be different, which will affect the subsequent filling and injection molding. The design of an asymmetrical wire clamp on both sides allows the wire harness to be centered while the highest point of the wire clamp protruding from both ends of the tail cover has the same thickness. The subsequent filling and injection molding can be designed into a symmetrical structure on both sides, which is beautiful in structure and can also save design costs.

[0042] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
