Abstract
The invention relates to the technical field of a coupler, in particular to an anti-short-circuit coupler and a shell body of the coupler. The coupler comprises the shell body and an operation module which is arranged in the shell body. The shell body is provided with an upper cover and a lower cover. The upper cover is provided with an upper cover groove. The lower cover is provided with a lower cover groove. A wire hole is defined by the upper cover grove and the lower cover groove when the upper cover is buckled with the lower cover. A wire pressing cylinder component is detachably arranged in the wire hole. The wire pressing cylinder component comprises an inner wire pressing cylinder and an outer wire pressing cylinder. An annular passage which is used for a wire shielding layer to enter is arranged between the inner periphery surface of the outer wire pressing cylinder and the outer periphery surface of the inner wire pressing cylinder. When the coupler is used, an inner conductor of a wire penetrates the inner wire pressing cylinder to enter the shell body, the wire shielding layer enters the annular passage and is fixed, and thereby the inner conductor of the wire is separated from the shielding layer by the inner wire pressing cylinder, therefore the problem that the wire shielding layer is capable of puncturing an insulator and then contacting with the inner conductor is solved, namely, the problem that the shielding layer and the inner conductor of the existing coupler are prone to short-circuiting is solved.
Description
Technical field

Background technology
Coupler refers to the device of transmitted power between system.In microwave system, often Xu Jiang mono-road microwave power is divided into a few road in proportion, Here it is power distribution problems, and the element realizing this function is called power division components and parts and coupler.Existing coupler includes housing and establishes operational module in the housing, described housing comprises the lower cover and upper cover that snap together mutually, the two ends place of lower cover is respectively equipped with the lower cover groove of arc, the two ends of upper cover be provided with under upper cover groove corresponding to the lower cover groove that covers, lower cover groove and upper cover groove are spliced to form the cable-through hole passed in and out for wire after lower cover and upper cover fasten, and wherein the bottom land of upper cover groove and/or lower cover groove is provided with penetrating welding operation hole, operational module comprises printed board, during use, wire (as Fig. 1) is introduced among the housing of coupler by the cable-through hole of correspondence, then with soldering of printed boards, in order to ensure the quality of Signal transmissions, wire all has screen 101, after upper cover and lower cover fasten, the screen 101 of wire is just arranged in corresponding cable-through hole, then screen 101 is welded and fixed by scolding tin from the welding operation hole of correspondence, but screen 101 is all woven by the shielding silk of a rule, its end is extremely sharp, and in use, screen 101 be to be blocked by the position stretching into corresponding cable-through hole from it (screen and housing are electrically connected, do not enter in coupler), when adopting said structure, the spine that the end (disconnect position place) shielding silk is formed easily punctures the insulating barrier (between screen and inner wire) of wire, thus with inner wire 102 conducting, the dielectric voltage withstand performance of coupler is finally caused to lose efficacy.
In sum, there is the screen of wire and the hidden danger of inner wire short circuit in current coupler.
Summary of the invention
The object of the present invention is to provide a kind of against short-circuit coupler preventing the screen of wire from puncturing wire insulation, with the problem of the easy short circuit of screen and inner wire solving existing coupler.
The present invention also aims to the housing that above-mentioned against short-circuit coupler is provided simultaneously.
In order to solve the problem, against short-circuit coupler of the present invention is by the following technical solutions: against short-circuit coupler, comprise housing and establish operational module in the housing, housing has upper cover and lower cover, upper cover has upper cover groove, lower cover has lower cover groove, upper cover groove and lower cover groove are upper, lower cover surrounds cable-through hole when fastening, dismountablely in described cable-through hole be fixedly equipped with barrel assembly, barrel assembly comprises interior barrel and is enclosed within the outer barrel in interior barrel, there is between the inner peripheral surface of outer barrel and the outer peripheral face of interior barrel the circular passage entered for conductor shield.
The inner of described interior barrel is provided with the gear edge of turning up, and this gear is along stopping that outer barrel is to the movement in housing.
Outer end place in interior barrel in the outside wall surface of interior barrel is provided with conical guide surface.
The inner face of outer barrel is connected by chamfered transition with between inner peripheral surface.
The barrel of described outer barrel is provided with inside and outside penetrating welding operation hole.
Fluid coupling shell of the present invention is by the following technical solutions: fluid coupling shell, comprise upper cover and lower cover, upper cover has upper cover groove, lower cover has lower cover groove, upper cover groove and lower cover groove surround cable-through hole when upper and lower cover fastens, dismountablely in described cable-through hole be fixedly equipped with barrel assembly, barrel assembly comprises interior barrel and is enclosed within the outer barrel in interior barrel, has the circular passage entered for conductor shield between the inner peripheral surface of outer barrel and the outer peripheral face of interior barrel.
The inner of described interior barrel is provided with the gear edge of turning up, and this gear is along stopping that outer barrel is to the movement in housing.
Outer end place in interior barrel in the outside wall surface of interior barrel is provided with conical guide surface.
The inner face of outer barrel is connected by chamfered transition with between inner peripheral surface.
The barrel of described outer barrel is provided with inside and outside penetrating welding operation hole.
Barrel assembly is fixedly equipped with because against short-circuit coupler of the present invention is dismountable in its cable-through hole, barrel assembly comprises interior barrel and is enclosed within the outer barrel in interior barrel, there is between the inner peripheral surface of outer barrel and the outer peripheral face of interior barrel the circular passage entered for conductor shield, therefore, when in use, the inner wire of wire can be passed to enter housing from interior barrel, make the screen of wire enter into described circular passage to fix simultaneously, thus the inner wire of wire and screen are separated by interior barrel, the screen solving wire thus can puncture insulator and the problem contacted with inner wire, namely the screen of existing coupler and the problem of the easy short circuit of inner wire is solved.
Further, the gear of interior barrel the inner is along the trend of bootable conductor shield, even if the screen of wire turns up, prevent the screen of wire from puncturing its inner wire further, in addition, screen by outer barrel wire is pressed on gear along upper, thus alleviates the tension stress of wire inner wire, the tensile strength of lifting lead wire; Described guide surface can be the screen (shell-like) that interior barrel penetrates wire and provides convenience, and can prevent the screen of wire from being squeezed off in the outer face of interior barrel and the transition position of outer peripheral face simultaneously; The turnover that chamfering between the inner face of outer barrel and inner peripheral surface can be screen provides space, the screen of wire is prevented to be pressed down herein, welding operation hole can be conductor shield and provides operating position with welding of barrel assembly, makes can be connected reliably between screen with barrel assembly.
