Thereby if necessary, then rigid casing can provide additional waterproof sealing.
Industrial standard rf purposes terminator terminating junctor is called the f connector.A kind of connector provided by the invention has: a pair of f connector, and an electric conductor extends between them; With an overcoat or sleeve pipe, make whole connector become the unit of an airtight and rigidization thereby encapsulate this conductor.Because connector is rigidity, so between erecting stage, be difficult for by bending or damaged in collision during manual operation.The material of overcoat or sleeve pipe is such, and is as a whole thereby the joint at f connector place is made connector, is hermetically sealed on the meaning that the moisture that prevents to influence inner conductor is invaded.Sleeve pipe has suitable material, and this material provides the rigidity of electric conductor, solid encapsulation, yet is enough flexible, with the localized heat expansion of permission by the hardware of tap cascade, and eliminates this harm that is caused by variations in temperature.
Because conductor is fixed and is supported in the rigid casing, so identical mechanical is provided and is electrically connected by the use of such rigid connector.Owing to identical mechanical can be provided and be electrically connected, connector allows a kind of modular approach for multiport tap cascade.If the damage pedestal is installed one of tap, a pedestal that then only needs to change damage is installed tap rather than whole cascade, and the saving of set-up time and refuse is provided.
Best two f connectors point to general opposite direction.It is U-shaped that a kind of straightforward procedure that realizes this point makes connector.Easy installation that general U-shaped connector is a connector and workman near creating conditions.Because sleeve pipe is rigidity, so the setting of electric conductor is fixed, and can be chosen to satisfy particular characteristic standard during the connector assembling in advance, and creates conditions for the consistent electric property between connector.
The U-shaped shape can be the right angle basically.Although a kind of rigidity right angle U-shaped sleeve pipe can be provided, in order to strengthen the rigidity of connector in desired directions, the conductor that is encapsulated in the sleeve pipe can still have the smooth curve shape, thereby does not reduce its electric property.
Best, select the bending radius of conductor, thereby do not reduce the radio-frequency performance of conductor.The curvature of selecting is guaranteed by the rigidity package cover and is held constantly, thereby guarantees consistent rf performance.
A best f connector and the 2nd f connector engage by high compression and are attached on the rigid casing.Engage with high compression between the f connector at sleeve pipe and to help the gas-tight seal connector, prevent the intrusion of moisture, and prevent that also rf from leaking.
The one f connector can be protruding.The first and second f connectors can be protruding.The f connector can be the combination in any of projection and recessed f connector, as being required by the special-purpose that connects.
Preferably conductor is a coaxial cable.Conductor can be a screened coaxial cable.Wish that more conductor is three shielding RG59 coaxial cables of single-piece.
According to a second aspect of the invention, provide the cascade that a kind of pedestal is installed tap, at least one radio frequency path that is provided by a kind of electrical cnnector is provided in this cascade, and this connector comprises: one the one f connector; One the 2nd f connector; A conductor extends between first and second f connector; And a rigid casing, between first and second f connector, extend and encapsulate this conductor.
According to a third aspect of the invention we, provide the method for an electrical cnnector of a kind of manufacturing, this connector comprises: one the one f connector; One the 2nd f connector; A conductor extends between first and second f connector; And a rigid casing, between first and second f connector, extend and a kind of waterproof sealing that encapsulates this conductor is provided, the method comprising the steps of:
Assembling first and second f connector and the conductors in anchor clamps are to be held in conductor best the setting;
Provide a mould around f connector and conductor, and a kind of sealed compound is incorporated in the mould;
Stay the sealed compound slaking; And
Be enough to provide one to keep the best rigidization sleeve pipe that is provided with of conductor in case sealed compound has cure into, just take out mould and sealing conductor and f connector from anchor clamps.
On the other hand, f connector and conductor can be enclosed in the sleeve pipe of a pre-mold pressing or an original place in the sleeve pipe of conductor and connector mold pressing.
With reference to the following detailed description of accompanying drawing by specific illustrative embodiment, will understand the present invention better, in the accompanying drawings:
Fig. 1 a, b and c represent solid, side-looking and the end-view according to a kind of electrical cnnector of the present invention;
Fig. 2 represents the section of connector along the line AA ' shown in Fig. 1;
Fig. 3 is illustrated in the part of electrical cnnector during the manufacture process; And
Fig. 4 is illustrated in a kind of three 8 port pedestals of interconnection illustrative according to connector of the present invention is installed in the purposes of cascade of tap.

13The specific insulation of Ω cm.It has-36 ℃ glass transition temperature, 175C softening point and in the viscosity of 210 ℃ of following 3700mPas.
On the other hand, sleeve pipe can be by any suitable plastic materials mold pressing, and around conductor and the assembling of f connector, perhaps can be inserted into conductor and f connector in the mould before filling, and form plastic bushing nearby.
Connector has the U-shaped shape at basic right angle, but can hold the conductor with smooth curve shape.Connector has the length of 55mm, the thickness of 13mm and the height of 37mm.
The enough firm coaxial cable with protection packaging of sleeve pipe prevents to damage and keep the bending radius of cable 13.Yet because the characteristic of shell material, it has enough elasticity and flexibility, thereby it can contain the slight variation of size, makes moisture can enter connector and can not rupture or damage.Therefore it can contain the localized heat expansion of hardware and not damage its integrality, and the connector of for example weld metal of perfect rigidity can not contain this localized heat expansion.
With reference to Fig. 3,, three shielding RG59 coaxial cables 13 of a segment length make connector by being connected between the curling connector 11,12 of a pair of RG59.Then this assembly is remained in the anchor clamps, thereby coaxial cable has a kind of bending radius of the best, so that its rf performance does not reduce.This set that keeps cable, handle component remains in the anchor clamps simultaneously.Winding spare assembles a mould then, and the plastic sealing compound that rigid casing is provided is introduced in the mould, and stays slaking.In case sealing Macromelt compound enough rigidization just can remove mould and remove connector to maintenance and carrying cable setting from anchor clamps.
Now with reference to Fig. 4, be described in the use that pedestal is installed the connector of the present invention in the cascade of tap.The cascade list of three 8 port pedestal installation taps 41,42,43 is shown among Fig. 4.An input port 45 of RF power supply to one first tap 31, and the rf power of a low intermodulation circuit separation input in tap are to provide rf signal at eight output port places.
Stride across the straight-through output port of power of first tap 42 and the straight-through input port of power of second tap 42 and be connected, thereby rf power is offered second tap in cascade according to an electrical cnnector 46 of the present invention.Similarly, provide, to provide from the straight-through rf power of second tap, 42 to the 3rd taps 43 according to one second electrical cnnector 47 of the present invention.
Often caused damage before the further cable of tap port connected, when being in flexible coaxial cable form, caused inconsistent rf performance, and perhaps can damage port terminal straight-through power adapter.And the rigidity of electrical cnnector of the present invention reduces to damage, and the moisture that helps to prevent the rf signal degenerates.If use a cascade assembly, single damage port means that whole assembly needs to change in a tap so, causes the set-up time of significantly waste, equipment to reach the loss of service to the client.Yet, use connector of the present invention, can use the module installation method, only need to change the tap rather than the whole cascade of damage.The U-shaped shape of connector makes cascade easy for the technician, because can be easily the power straight-through port of tap and the f connector coupling of directly presenting to them.
