Abstract

The utility model connector comprises an insulation body. One inserting surface coated with a metallic layer is arranged on the insulation body. In comparison with existing technology, no metal casing and protective coating is required, thereby reducing effectively production process and lowering production cost. Moreover, metallic layer is coated on the inserting surface of the insulation body, which can not only effectively prevent electromagnetic interference, but also avoid the deformation of the insulation body towards the two sides.

Description

Connector

[technical field]

The utility model relates to a kind of connector, refers in particular to the connector that is coated with metal level.

[background technology]

In electric connector field; especially in high frequency communication field of connectors; often use metal shell to fix the interior insulating body of electric connector; like this; metal shell can hide insulating body and be contained in several interior conducting terminals of this insulating body; reduce outside electromagnetic interference (Electromagnetic Interference whereby; EMI) to the influence of institute's transmission signal in the connector; as this metal shell being located at the front end of insulating body; not only can reduce outside electromagnetic interference; but also can prevent effectively that insulating body is to its both sides bowing; but this metal shell generally need be made according to the shape of insulating body, and also need plate layer protecting film outside metal shell after the moulding, to prevent the metal shell oxidation; this not only increases production cost, and the production process trouble.

Therefore, be necessary to design a kind of novel connector, to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of connector that is coated with metal level on the plug surface of insulating body.

In order to reach above-mentioned creation purpose, the utility model connector comprises insulating body, and described insulating body is provided with a plug surface, is coated with a metal level on the described plug surface.

Compared with prior art; because the metal level of the utility model connector is to be plated on the plug surface of insulating body; do not establish diaphragm and do not need to refill to establish metal shell and plate in addition; can effectively reduce production process; reduce production costs; and metal level is established in plating on the plug surface of insulating body, not only can effectively prevent electromagnetic interference, but also can prevent that insulating body is to its both sides bowing.

[embodiment]

Below in conjunction with accompanying drawing the utility model connector is described further.

See also Fig. 1 to shown in Figure 4, the utility model connector 10 is used for an assembly (figure does not show) is connected to circuit board (figure does not show), comprises insulating body 11, metallic support 12, terminal 13 and this support 12 is fixed on two fixtures 14 on the insulating body 11.

See also Fig. 5 to shown in Figure 11, edge body 11 is provided with plug surface 111, is coated with metal level 20 on this plug surface 111.The both sides of described plug surface 111 respectively are provided with a through hole 112, also are coated with metal level 20 in this through hole 112, and wherein said fixture 14 is located in this through hole 112, also is coated with metal level 30 (as shown in Figure 10 and Figure 11) on this fixture 14.Have a protuberance 113 on the described plug surface 111, metal level 20 is also all arranged in the side of this protuberance 113.Described protuberance 113 is provided with plurality of terminals spliced eye 114, terminal 13 is housed in this terminal spliced eye 114, in this spliced eye, be coated with metal level 40 (as shown in Figure 7 and Figure 8), and the rear end of insulating body 11 and lower end also are respectively equipped with a back seat 15 and a base 16, described back seat 15 can be fixed on terminal 13 in the described terminal spliced eye 114, and described base 16 both sides respectively offer an accepting groove 161, and this base 16 can be fixed the end of described terminal 13.

Support 12 is provided with the accepting hole 121 corresponding with the through hole 112 of insulating body 11, the through hole 112 of described fixture 14 by insulating body 11 is to be fixed on support 12 on the insulating body 11, and the utility model connector 10 also is provided with a stop part 17, these stop part 17 correspondences are located at the rear end of the accepting hole 151 of support 12, and be fixed on the fixture 14, come off from insulating body 11 to prevent support 12.The both sides of described support 12 also are provided with two pins 122, and this pin 122 can be contained in the accepting groove 161 of described base 16, and this pin 122 can pass this accepting groove 161, the utility model connector 10 is fixed on the circuit board (figure does not show).

Described

metal level

20,30,40 all is that the mode with the object plated film obtains, and this physical coating can be vacuum evaporation, also can be vacuum splashing and plating.

When adopting vacuum evaporation, its basic principle is the material heating evaporation of making film, make it be deposited on object surfaces to be plated, promptly the free path of air molecule reaches 0.5m when the pressure in the coating chamber is 1.3mpa, arrive the much bigger of thing to be plated than evaporation source apart from the 0.1m left and right sides, therefore to arrive in the process of thing to be plated probability with gas molecule collision very little for evaporation atom, can think, evaporation source is a point source, in the boat that evaporating materials is seated in the basket that tungsten filament makes or molybdenum sheet is made, when tungsten basket or molybdenum boat moment during by big current flow heats, material vaporization to be evaporated, its molecule is deposited on the surface of thing to be plated to space ejaculation all around with straight path, be plug surface 111 in the present embodiment, 113 of through hole 112 and protuberances, and the surface of terminal spliced eye 114 and fixture 14 forms film, this kind method price is lower, easily processing.

When adopting vacuum splashing and plating, its basic principle be when high energy particle can be that cation that electric field quickens is when beating coated body surperficial, atom or molecule positive energy exchange with the surface, thereby make these atoms, molecule splashes out and forms coatings on thing to be plated surface, promptly under the high vacuum state, charge into an amount of argon gas; The high-pressure direct current is ionized into argon ion with argon gas, and the accelerating impact metal targets sputters metal ion; Metal ion in electric field, quicken to sputter at base material (in the present embodiment for plug surface 111, through

hole

112 and 113 of protuberances, and the surface of terminal spliced eye 114 and fixture 14) on, form metal ion film.

Certainly, it is unrestricted to desire sputter material, and solid-state conducting metal of any normal temperature and organic material, insulating material all can use (example: copper, chromium, silver, gold, stainless steel, aluminium, silicon oxide sio 2 etc.).By sputter base material several unrestricted (ABS, PC, PP, PS, glass, pottery, epoxy resin etc.).Its membranous densification is even, thickness is controlled easily, tunic more than the strong adhesion (ASTM3599 method test 4B), the multiple different sputter material of can arranging in pairs or groups simultaneously.And, can be with client's specify transformations coating order, and this kind method price is lower, and easily processing is made short production capacity height, and is not had the environmental protection problem.

Because the metal level of the utility model connector is to be plated on the plug surface of insulating body; do not establish diaphragm and do not need to refill to establish metal shell and plate in addition; can effectively reduce production process; reduce production costs; and metal level is established in plating on the plug surface of insulating body; not only can effectively prevent electromagnetic interference, but also can prevent that insulating body is to its both sides bowing.
