[0002] In rocket engine testing, cables and cable plugs are used. The cables and cable plugs are welded together. The cable plugs have multiple welding points, so multiple cables can be welded together. Because these cables are in a high heat flux and high vibration environment when they are working, the welding requirements for the cables and cable plugs are high.

[0003] Typically, to ensure the reliability of cable and cable plug welding, welding fixtures are made to fix the cable plug. The welding fixtures can adjust the angle between the cable plug and the horizontal plane to facilitate welding.

[0004] However, traditional welding fixtures are difficult to adjust the angle between the cable plug and the horizontal plane precisely, making them inconvenient to use. Summary of the Invention

[0006] To achieve the above objectives, this application provides a cable plug welding fixture for fixing a cable plug. The cable plug welding fixture includes: a base, a connecting post, a ball head, a protrusion, and a clamping part.

[0009] Optionally, the cable plug welding fixture further includes: multiple labels, each label corresponding to one of the through holes.

[0010] Optionally, the through holes are arranged in the circumferential and axial directions of the clamping portion; wherein each label is fixed to the same end of the clamping portion, and the through holes are directly opposite the corresponding labels in the axial direction of the clamping portion.

[0025] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Figure 1 This is a schematic diagram of the overall structure of a cable plug welding fixture used in an embodiment of this application. Figure 2 for Figure 1 A structural breakdown diagram of the Chinese embodiment; Figure 3 This is a schematic diagram of the structure of the connection area between the upper and lower shells in an embodiment of this application.

[0027] It should be understood that, Figure 2 The connections between the various components should be like Figure 1 As compact as in the middle, this is only for illustrative purposes and will Figure 2 The components in the middle section are displayed separately for easier understanding.

[0028] It should be noted that in the traditional solution, the end of the cable plug 1 that is used to weld multiple cables needs to be tilted up relative to the horizontal plane to create an angle between the cable plug 1 and the horizontal plane, so as to facilitate the welding of multiple cables and prevent the solder from slipping. When welding cables with different specifications of cable plug 1, the angle between the cable plug 1 and the horizontal plane needs to be adjusted accordingly. However, traditional welding fixtures mostly adjust the angle between the cable plug 1 and the horizontal plane by manually turning it, which is not precise enough and makes welding inconvenient.

[0029] refer to Figures 1-3This application provides a cable plug welding fixture for fixing a cable plug 1. The cable plug welding fixture may include: a base 2, a connecting post 3, a ball head 4, a protrusion 5, and a clamping part. One end of the connecting post 3 is fixed to the base 2; the ball head 4 is fixed to the end of the connecting post 3 away from the base 2; the protrusion 5 is fixed to the ball head 4; the clamping part is used to fix the cable plug 1, and the clamping part is provided with a plurality of through holes 61, and a groove 62 is provided on the side wall of each through hole 61; wherein, the ball head 4 passes through a through hole 61, and the protrusion 5 fits into the corresponding groove 62 to lock the angle between the axial direction of the cable plug 1 and the axial direction of the connecting post 3; when the protrusion 5 fits into different grooves 62, the angle between the axial direction of the cable plug 1 and the axial direction of the connecting post 3 is different.

[0030] The cable plug welding fixture proposed in this application provides that, in use, the cable plug 1 is clamped and fixed on the clamping part. When the ball head 4 is inserted into different through holes 61 and the protrusion 5 fits into the corresponding groove 62, the included angle between the axial direction of the cable plug 1 and the axial direction of the connecting post 3 is different. The axial direction of the connecting post 3 is vertical. The included angle between the cable plug 1 and the horizontal plane can be adjusted by changing the through hole 61 into which the ball head 4 is inserted. Furthermore, due to the cooperation between the protrusion 5 and the groove 62, the angle of the cable plug 1 after adjustment is more accurate.

[0031] It should be noted that the base 2 can be disc-shaped and placed horizontally, so that the thickness direction of the base 2 is the same as the direction of gravity, and the axis of the connecting column 3 can be the same as the direction of gravity, so that the ball head 4 is fixed to the top of the connecting column 3.

[0032] It should be understood that after the ball head 4 is inserted into a certain through hole 61, the clamping part can rotate around the ball head 4 at multiple angles. When the rotation reaches the point where the protrusion 5 is engaged in the groove 62, the relative position of the clamping part and the ball head 4 is fixed. At this time, the angle between the axis of the cable plug 1 and the axis of the connecting post 3 is fixed, and the cable plug 1 forms a certain angle with the horizontal plane, causing the end of the cable plug 1 that is welded to the cable to be raised, and the angle adjustment is more precise.

[0033] It should be noted that the grooves 62 in different through holes 61 are set at different angles, so when the protrusion 5 is inserted into different grooves 62, the axial angle between the cable plug 1 and the connecting post 3 is different.

[0034] In an exemplary embodiment, the clamping part is cylindrical, and the cable plug 1 is located on the inner periphery of the clamping part and the two have the same axis; wherein, the through hole 61 connects the inner side and the outer side of the clamping part.

[0035] refer to Figure 2In an exemplary embodiment, the protrusion 5 is annular and its axial direction coincides with the axial direction of the connecting post 3, and the axial direction of the protrusion 5 passes through the center of the ball head 4; the groove 62 is annular and its axial direction intersects with the axial direction of the cable plug 1 and the two are set at an angle.

[0036] Specifically, when the clamping part can rotate around the ball head 4 at multiple angles, the axial direction of the groove 62 and the axial direction of the clamping part continuously change. When the protrusion 5 is inserted into the groove 62, the axial direction of the groove 62 and the axial direction of the protrusion 5 are the same, both being the direction of gravity.

[0037] For example, in the design, if the axial direction of the cable plug 1 needs to be horizontal, the axial direction of the groove 62 can be made perpendicular to the axial direction of the clamping part. In this way, when the protrusion 5 is inserted into the groove 62, the axial direction of the cable plug 1 is horizontal. If the axial direction of the cable plug 1 needs to form a 30° angle with the horizontal plane, the axial direction of the groove 62 can be made to form a 60° angle with the axial direction of the clamping part. In this way, when the protrusion 5 is inserted into the groove 62, the axial direction of the cable plug 1 is 30° with the horizontal plane, and so on.

[0038] Furthermore, the axial direction of the through hole 61 is the same as the axial direction of the corresponding groove 62, so that the connecting post 3 and the ball head 4 can be inserted into the corresponding through hole 61.

[0039] In an exemplary embodiment, the cable plug welding fixture may further include: multiple labels, each label corresponding to one of the through holes 61.

[0040] Specifically, the label can be used to record the angle at the corresponding through hole 61. For example, if the ball head 4 is inserted into the through hole 61 and the protrusion 5 is engaged with the groove 62, the angle between the cable plug 1 and the horizontal plane is 30°. Then a label can be set next to the corresponding through hole 61 to record 30°, so as to quickly determine the through hole 61 into which the ball head 4 needs to be inserted.

[0041] In an exemplary embodiment, each through hole 61 is arranged in the circumferential and axial directions of the clamping portion; wherein each label is fixed to the same end of the clamping portion, and in the axial direction of the clamping portion, the through hole 61 is directly opposite the corresponding label.

[0042] Furthermore, such as Figure 1 As shown, the through holes 61 can also be arranged in the axial direction of the clamping part, or the through holes 61 can be arranged in both the circumferential direction and the axial direction of the clamping part. In a limited space, the number of through holes 61 can be increased as much as possible, thereby increasing the range of angles in which the cable plug 1 can be rotated precisely.

[0043] refer to Figures 1-3 In an exemplary embodiment, the clamping part may include an upper housing 63 and a lower housing 64, which are detachably connected to form the inner periphery of the clamping part.

[0044] Both the upper housing 63 and the lower housing 64 can be semi-circular. Thus, when the upper housing 63 and the lower housing 64 are connected, a cylindrical clamping part can be formed. In this embodiment, the cable plug 1 is clamped by connecting the upper housing 63 and the lower housing 64.

[0045] It should be understood that when the semi-circular upper shell 63 and the lower shell 64 are docked, there are two connection areas, and each connection area is provided with a connection structure to realize the detachable connection between the upper shell 63 and the lower shell 64.

[0046] refer to Figure 2 and Figure 3 In an exemplary embodiment, the connection structure may include: a locking strip 631 and a locking groove 641. The locking strip 631 is disposed on the upper housing 63 and extends axially along the clamping portion; the locking groove 641 is disposed on the lower housing 64 and extends axially along the clamping portion, and the locking strip 631 is correspondingly engaged in the locking groove 641.

[0047] Specifically, the upper housing 63 and the lower housing 64 are connected by engaging the locking strip 631 with the locking slot 641. The engagement methods of the locking strip 631 and the locking slot 641 are as follows: Firstly, in the radial direction of the clamping part, the width of the slot 641 is smaller than the width of the clip 631; thus, after the clip 631 deforms and is squeezed into the slot 641, the relative positions of the upper housing 63 and the lower housing 64 can be locked. Without applying external force, the clip 631 and the slot 641 will not separate, thus connecting the upper housing 63 and the lower housing 64.

[0048] Secondly, such as Figure 3 As shown, there are two of each of the locking strips 631 and the slots 641, which are spaced apart in the radial direction of the clamping part. In the radial direction of the clamping part, the distance between the two locking strips 631 is less than the distance between the two slots 641. Thus, when the two locking strips 631 are inserted into the corresponding slots 641 respectively, the two locking strips 631 can press the structure in the middle part of the two slots 641, thereby locking the relative position of the upper housing 63 and the lower housing 64. The upper housing 63 and the lower housing 64 will not separate without the application of external force.

[0049] Of course, the two card strips 631 and card slots 641 mentioned above can be used at the same time, which will result in a better connection effect.

[0050] It should be noted that in this embodiment, the base 2, connecting column 3, ball head 4 and protrusion 5 can be integrally formed to form a support structure; the upper shell 63 and the clip 631 can also be integrally formed. Thus, when assembling and welding the fixture, only three parts exist: the support structure, the upper shell 63 and the lower shell 64, making assembly convenient and quick.

[0051] In addition, all components in this application are made of lightweight plastic to reduce the overall weight of the tooling and make it more convenient to use. Furthermore, all components can be manufactured by 3D printing. 3D printing facilitates the processing of small-sized structures such as protrusions 5 and grooves 62, with high processing precision, short cycle time, and can be manufactured directly on the work site. Once completed, they can be put into use, which is convenient and quick.

[0052] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
