Description

Technical Field

[0001] The utility model relates to the technical field of manual tinning of wires, in particular to a manual tinning fixture for star wires. Background Art

[0002] Currently, satellite electronic products, as the main functional components of satellites, such as C55 / 0112 type conductors, have been widely used in satellite electronic products. The quality of conductor tinning is directly related to the reliability of welding, which in turn affects the performance and service life of the product.

[0003] At present, C55 / 0112 type conductors are mostly tinned by hand, and it is difficult to ensure that the quality of the tinning meets the requirement of QJ3268-2006 "Technical Requirements for Conductor End Treatment Technology" that "a 0.5mm to 1mm non-tinned length should be left at the root of the core wire". During manual tinning, tin can easily enter the insulation layer of the conductor, causing stress at the root of the connection between the wire core and the insulation skin during subsequent welding. There is a risk of wire breakage during long-term use, which affects product performance. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the utility model provides a manual tinning fixture for star-type conductors.

[0005] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0006] A manual tinning fixture for star-type conductors comprises a first clamping arm and a second clamping arm, wherein one end of the first clamping arm and the second clamping arm is fixed and a connecting plate is symmetrically fixed to the other end, the ends of the connecting plates are symmetrically provided with clamping plates, and the clamping plates both extend out of the first clamping arm and the second clamping arm; a plurality of semicircular grooves are symmetrically arranged on opposite surfaces of the clamping plates, and when the two clamping plates abut against each other, the two opposite semicircular grooves enclose a circular through hole, and the diameter of the circular through hole is equal to the outer diameter of the core of the star-type conductor.

[0007] Furthermore, the connecting plate and the clamping plate are an integrated structure, and the clamping plate is in a horizontal posture. The connecting plate is vertically arranged and fixedly connected to the ends of the first clamping arm and the second clamping arm by screws.

[0008] Preferably, the thickness of the clamping plate is 0.7-0.9 mm.

[0009] Furthermore, four semicircular grooves with different radii are symmetrically arranged on the opposite surfaces of the clamping plates. When the two clamping plates are abutted against each other, the two opposite semicircular grooves respectively enclose four circular through holes with different diameters to accommodate the clamping of four different specifications of star-use conductor cores.

[0010] Beneficial effects of the utility model:

[0011] 1. The structure of the utility model is simple and reasonable. The clamping plate is connected to the end of the clamping arm by a connecting plate screw. The clamping plate can be replaced at any time when it needs to be replaced. It is easy to disassemble and assemble, and the operation is simple;

[0012] 2. By rationally designing the thickness of the clamping plate, the non-tinning distance between the wire core and the insulation can be effectively guaranteed, avoiding stress on the connection root between the wire core and the insulation, thus improving the consistency and reliability of the wire tinning quality.

[0019] The present invention is further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0020] See also Figures 1 to 3The utility model provides a manual tinning fixture for star-type conductors, the conductor model is C55 / 0112, and the fixture specifically includes a first clamping arm 1 and a second clamping arm 2, one end of the first clamping arm 1 and the second clamping arm 2 is fixed, and the other end has two symmetrical fixing holes, and a connecting plate 4 is fixed in the fixing hole by a cross-slot countersunk screw 3, and the ends of the two connecting plates 4 are symmetrically provided with clamping plates 5, and the clamping plates 5 are both extended from the first clamping arm 1 and the second clamping arm 2; Φ0.76m is symmetrically arranged on the opposite surfaces of the two clamping plates 5 m, Φ0.60mm, Φ0.48mm and Φ0.38mm four diameter specifications of semicircular grooves 5-1, when the two clamping plates 5 are against each other, the two opposite semicircular grooves 5-1 are enclosed to form four diameters of circular through holes 5-2 of Φ0.76mm, Φ0.60mm, Φ0.48mm and Φ0.38mm respectively, and the four specifications of circular through holes 5-2 are respectively equal to the outer diameters of the wire cores of four commonly used specifications of wires 6 of C55 / 0112 type 22, 24, 26, 28 after removing the insulation skin, thereby realizing the clamping and fixation of the wire cores of the four wires.

[0021] Preferably, the connecting plate 4 and the clamping plate 5 are an integrated structure, and the clamping plate 4 is in a horizontal posture. The connecting plate 4 is vertically arranged and fixedly connected to the ends of the first clamping arm 1 and the second clamping arm 2 by a cross slot countersunk screw 3; in addition, the first clamping arm 1 and the second clamping arm 2 are both made of stainless steel, which is rust-proof, wear-resistant, high in hardness and not easy to deform. When the operator applies force to the first clamping arm 1 and the second clamping arm 2 inward at the same time, the ends of the first clamping arm 1 and the second clamping arm 2 can be abutted against each other; when the clamping plate 5 is damaged or a wire core of different specifications needs to be tinned and the clamping plate 5 needs to be replaced, it is only necessary to remove the original connecting plate 4 by the cross slot countersunk screw 3, and then install a new or qualified clamping plate 5.

[0022] Preferably, the thickness of the clamping plate 5 is 0.7~0.9mm, which can fully guarantee the technical requirement of the untinned length. Even if the tin material partially penetrates into the clamping plate 5 during tinning or the wire core outside the clamping plate 5 is not completely tinned, there is enough margin to make the final product meet the technical requirements.

[0023] Preferably, the connecting plate 4 and the clamping plate 5 are made of beryllium bronze or aluminum alloy, which is beneficial to the heat dissipation of the product; the first clamping arm and the second clamping arm are both made of stainless steel.

[0024] The working process of the manual tinning fixture is:

[0025] The insulation skin of the wire end to be welded is peeled off and placed in the corresponding aperture of the clamping plate 5, with the end of the insulation skin abutting against the end face of the clamping plate 5. Then, the wire core at the lower end of the clamping plate 5 is tinned. The length of the wire core of the clamped part is set between 0.7 and 0.9 mm to ensure that the technical requirement of 0.5 to 1 mm of untinned length should be left at the root of the wire core. Finally, the manual tinning is completed.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
