Description
Technical field
The utility model relates to the connector technique field of mobile telecommunication service device equipment, especially relates to a kind of connector improving signal transmission reliability and stability.
Background technology
Along with the development of telecommunications industry, from the application of initial just voice, develop into and had now the application such as mobile Internet and mobile TV, more and more higher to the requirement of data transmission rate.Along with the development of wireless communication technique, plate is more and more extensive to the application of the connector of cable in wireless system module is interconnected to plate and plate, as: communication base station, RRH, repeater, GPS device and other similar application etc.At first, between radio-frequency module plate, the main cable assembly that relies on connects, but, along with product is miniaturized, the connection between parts is more and more compacter, and cable assembly cannot meet the demands, therefore plate meets the tendency to wire and cable connector to plate and plate, simultaneously from limited tolerance to large tolerance future development.
In order to transmit the transfer rate of higher communication equipment and keep the integrality of its signal, thus also more and more higher to the performance requirement of communications connector.Connector, when carrying out Signal Integrity Design, needs the continuity considering connector and whole interconnected transmission line impedance, the crosstalk between each contact pin of connector.The plastic body energy fixing metal terminal of communications connector achieves signal and transmits integrality, the integrality that the signal that the size thickness of plastic body and position shape can affect transmits.The metal terminal of connector can keep stabilization signal transmission in the application, and this plastic body just needing rock-steady structure supports.
Existing product design, after plastic body is shaping, at plastic body in injection molding process, plastic cement stream meet formed joint line, the joint line of current plastic body on the thin-walled of two terminal holes, when after inserted terminals, the thin-walled of plastic body easily ftractures, cause the confining force of terminal in plastic body not enough, affect the stability of connector transmission signal, reduce the application function of product.Therefore be necessary to be improved.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of connector improving signal transmission reliability and stability, the original design of its improved products, changes the position of joint line, the situation that after solving inserted terminals, the thin-walled of plastic body easily ftractures.
To achieve these goals, the technical scheme that the utility model adopts is.
A kind of connector improving signal transmission reliability and stability, comprise shielded metal shell, plastic body and some terminals, plastic body is fixed in shielded metal shell, plastic body offers some installing holes, short transverse plastic body along plastic body is arranged with several rows installing hole, each terminal is inserted in the installing hole of plastic body respectively, and often the one or both sides of row installing hole are provided with rib, in injection molding process plastic cement flowing velocity faster rib offer draw material hole.
In further technical scheme, in injection molding process plastic cement flowing velocity faster rib spaced apart be provided with some draw material hole.
In further technical scheme, between two installing holes that the Width of plastic body is adjacent, form thin-walled, the joint line formed in plastic body injection molding process is positioned at the position beyond thin-walled.
In further technical scheme, described in draw material hole two ends up and down to align respectively the thin-walled of upper and lower both sides
In further technical scheme, described in draw the cross sectional shape in material hole for circular, oval or square or rectangular.
After adopting said structure, the utility model is compared to the prior art advantageously: the utility model structure is simple, the Stability Analysis of Structures of product, to reduce after assembling product the scrapping of causing at joint line place cracking, and improve the shortcoming of plastic body injection mo(u)lding, improve process capability, reduce its cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of plastic body of the present utility model.
In figure:
1, shielded metal shell 2, plastic body 3, installing hole 4, rib 5, draw material hole 6, thin-walled.
Embodiment
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.
Embodiment, see shown in Fig. 1 to Fig. 2, a kind of connector improving signal transmission reliability and stability, connector shown in the present embodiment is communication equipment E1T1 communications connector, comprise shielded metal shell 1, plastic body 2 and some terminals, plastic body 2 is fixed in shielded metal shell 1, plastic body 2 offers some installing holes 3, short transverse plastic body 2 along plastic body 2 is arranged with several rows installing hole 3, each terminal is inserted in the installing hole 3 of plastic body 2 respectively, often the one or both sides of row installing hole 3 are provided with rib 4, in injection molding process plastic cement flowing velocity faster rib 4 offer draw material hole 5.
Concrete, in injection molding process plastic cement flowing velocity faster spaced apart being provided with of rib 4 somely draw material hole 5.Thin-walled 6 is formed between two installing holes 3 that the Width of plastic body 2 is adjacent, the joint line formed in plastic body 2 injection molding process is positioned at the position beyond thin-walled 6, joint line after plastic body 2 is shaping moves to the home of nonfunctional impact, improve the structural strength of thin-walled 6, after inserted terminals, thin-walled 6 is not easily damaged.Align the respectively thin-walled 6 of upper and lower both sides of the two ends up and down of drawing material hole 5 draws the cross sectional shape in material hole 5 for circular, oval or square or rectangular.The utility model improves the structure of connector, and the signal improving connector transmits reliability and stability.The Stability Analysis of Structures of product, to reduce after assembling product the scrapping of causing at joint line place cracking, and improves the shortcoming of plastic body 2 injection mo(u)lding, improve process capability, reduce its cost.
In addition, existing product design, when plastic body 2 injection mo(u)lding, in different ribs 4, the speed difference of plastic cement flowing is comparatively large, causes shaping rear plastic body 2 to have insatiable hunger mould phenomenon and product stripping difficulty situation.The original design of the utility model improved products, when plastic body 2 injection mo(u)lding, in different ribs 4, the speed difference of plastic cement flowing reduces, and improves its shaping situation.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
