1) split housing realizes right-angled bend by being press-fitted silver soldering mode, this frame mode is normally used is at present the housing of brass material, housing is directly press-fitted location, ensure that two body housings reliably connect by the mode of silver soldering, but easily by the impact of processing dimension tolerance, weld time, welding temperature, this structure connector overall dimension is comparatively large, and processing cost is higher, and electrical property consistency is poor.
2) split housing realizes right-angled bend by threaded engagement connected mode, this frame mode is normally used is at present the housing of brass or stainless steel material, housing is connected by the mode of threaded engagement, connector overall dimension is larger, processing cost is higher, and two body case threaded engagement reliably need use screw threads for fastening agent for ensureing to connect, but the use of the double thread fastening agents such as space flight and aviation has certain restriction, this kind of frame mode is had some limitations in use, and the electrical property consistency of this structure is also comparatively difficult to ensure card simultaneously.
3) bend pipe structure, adopts shaping bend pipe to realize right-angled bend, and this frame mode body shell material can with brass or stainless steel, and red copper material generally selected by bend pipe, by the impact of be shaped material size and material, the specification of connecting cable is restricted.
Summary of the invention
For improving the limitation of above-mentioned existing structure form, the purpose of this utility model is to provide a kind of bent radio-frequency coaxial electric coupler connecting flexible cable, structure is simple, highly versatile, solve that split housing electric connector overall dimension is comparatively large, processing cost is high, the problem of complex structure, electrical property consistency difference, also solve the limitation of shaping bend pipe in addition.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of bent type radio frequency coaxial connector connecting flexible cable, comprise the inner wire 4 welded with cable core, be arranged on the outer lining 2 welded with cable shield of inner wire 4, be arranged on the housing 1 outside lining 2, also comprise the band breach screw 3 that can bend, cable jacket loads band breach screw 3 endoporus that can bend, and the described band breach screw 3 that can bend loads between lining 2 and housing 1, and is threaded connection with housing 1.
The monnolithic case of the described band breach screw 3 that can bend is annular, leaves be not more than 1/4 circular arc wall at tail end mid portion, forms breach, is convenient to bend.
Compared to the prior art, tool has the following advantages the utility model:
The combination of what 1, structure of the present utility model adopted is straight connector and flexible screw, can realize connector optimum electrical performance indexes.
2, the utility model avoids existing silver soldering right-angle structure and threaded engagement right-angle structure Product processing difficulty, simplifies production process, improves the qualification rate of product, reduce production cost; Also improve the reliability of product in addition.
3, flexible bolt structure of the present utility model can bend according to the practical situations of assembly, meets the requirement of the minimum bending radius of cable when can ensure bending, avoids direct bending cable to the damage of the construction of cable, on the impact of electrical property.
4, flexible bolt structure of the present utility model avoids the limitation of existing bend pipe structure, decreases the complexity of bend pipe structure assembling, improves the reliability of product.
In a word, the utility model solves the problem such as processing difficulties, qualification rate is low, cost is high, application limitation that prior art structure exists, and improves product reliability and electric property, electrical property consistency, extend the scope of application of connector, form seriation, there is great generalization.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, for the bent type radio frequency coaxial connector schematic diagram of existing silver soldering structure, after shell body A and shell body B is press-fitted, connected by the mode of silver soldering, this kind of structure, by processing dimension, the impact coordinating the amount of being press-fitted, silver soldering temperature and time, easily causes combined shell silver soldering place to be out of shape; This construction profile size is comparatively large, processes more difficult; The electrical property of this kind of structure can be subject to the limitation of structure itself in addition, and consistency is poor, and qualification rate is low.
As shown in Figure 2, for the bent type radio frequency coaxial connector schematic diagram of existing threaded engagement structure, shell body C is connected by threaded engagement with shell body D, connector overall dimension is larger, processing cost is higher, and two body case threaded engagement reliably need use screw threads for fastening agent for ensureing to connect, but the use of the double thread fastening agents such as space flight and aviation has certain restriction, makes this kind of frame mode have some limitations in use; Electrical property is by the impact of structure itself in addition, and consistency is difficult to ensure card.
As shown in Figure 3, for the bent type radio frequency coaxial connector schematic diagram of existing bend pipe structure, what adopt is the combination of straight connector and shaping bend pipe, shaping bend pipe F welds with cable after welding with housing E again, this structure operation is complicated, and by the impact of expecting size and material that is shaped, the specification of connecting cable is restricted.
As shown in Figure 4, the bent type radio frequency coaxial connector schematic diagram of flexible cable is connected for the utility model is a kind of, comprise the inner wire 4 welded with cable core, be arranged on the outer lining 2 welded with cable shield of inner wire 4, be arranged on the housing 1 outside lining 2, also comprise the band breach screw 3 that can bend, cable jacket loads band breach screw 3 endoporus that can bend, the described band breach screw 3 that can bend loads between lining 2 and housing 1, and is threaded by wall with housing 1.The band breach screw 3 that can bend can bend according to actual service condition, when bending, this structure can ensure that cable meets the minimum bending radius of cable, and damage can not be caused to cable, the combination of what this kind of structure connector adopted is straight connector and flexible screw, straight connector can farthest meet electrical performance indexes requirement, and consistency is high, therefore the connector assembly of this curved formula structure can ensure electrical performance indexes, improves the consistency of electrical property.
Connector with the connected mode of cable is: inner wire 4 welds with cable core, after lining 2 welds with cable shield, loads housing 1, and band breach screw 3 and housing 1 are screwed by the mode of threaded engagement and be connected.
As shown in Figure 5 a, the monnolithic case of the described band breach screw 3 that can bend is annular, just leaves at tail end mid portion and is not more than 1/4 circular arc wall, form breach, be convenient to bend.The material of the described band breach screw 3 that can bend is general optional brass or stainless steel, preferred stainless steel.
As shown in Figure 5 b, structural representation after the band breach screw for bending is bending.
