Abstract

The utility model relates to the technical field of connectors, in particular to an SIM card connector which comprises a plastic base, mounting grooves are arranged at both sides of the plastic base, metal terminals are inserted in the mounting grooves and provided with contact areas which contact the SIM card, the contact areas of the metal terminals are fabricated into a raised pyramid structure, and the top parts of the pyramid contact areas have an arc surface. The SIM card can be inserted in a mobile phone from four directions, and is not worn easily, thus leading to more reliable contact, improving the electrical performance of products, prolonging the mechanical service life of products, simplifying the structure, reducing punching procedures, decreasing difficulty in manufacture, and processing die formed workpieces easily.

Description

Sim card connector

Technical field:

The utility model relates to the connector technique field, refers in particular to sim card connector.

Background technology:

Along with the fast development of information technology, personal communication apparatus such as mobile phone obtain application more and more widely.Wherein as the SIM card of user identity identification, mainly realize and being electrically connected of circuit board of mobile phone by a sim card connector.

The mobile phone SIM card connector product is for obtaining terminal and the mobile phone clamping is touched well, plug-in card effect smoothly, hemisphere or other arc arc shapes are made in the contact zone that the existing structure of comparatively popularizing is a terminal, and the shortcoming of this product structure is that mould molding and production difficulty are big.

The utility model content:

The purpose of this utility model is exactly the sim card connector that a kind of simplified structure is provided, reduces manufacture difficulty, reduce wear at the deficiency of prior art existence.

To achieve these goals, the technical solution adopted in the utility model is: sim card connector, it includes the plastic cement pedestal, plastic cement pedestal both sides respectively are provided with mounting groove, be inserted with metal terminal in the mounting groove, metal terminal is provided with the contact zone that contacts with SIM card, and the contact zone of metal terminal is the tetrapyamid shape structure that raises up, and the top of tetrapyamid shape contact zone is an arc surface.

Each seamed edge of described tetrapyamid shape contact zone all is provided with fillet.

The bending downwards of the head front end of described metal terminal and respectively to the left and right both sides extend the step clamp arranged, the two side of mounting groove respectively offers the draw-in groove that cooperates with the step clamp, the step clamp is fastened in the draw-in groove.

The utility model beneficial effect is: the sim card connector that the utility model provides, it includes the plastic cement pedestal, plastic cement pedestal both sides respectively are provided with mounting groove, be inserted with metal terminal in the mounting groove, metal terminal is provided with the contact zone that contacts with SIM card, and the tetrapyamid shape structure that raises up is made in the contact zone of metal terminal, and the top of tetrapyamid shape contact zone is an arc surface, on mobile phone during plug-in card, SIM card all can be inserted from four direction, is not easy wearing and tearing, thereby makes contact more reliable, improved the electric property of product, improve product mechanical endurance, and simplify the structure, reduce stamping procedure, reduce manufacture difficulty, mould molding workpiece handling ease.

In addition, the bending downwards of the head front end of metal terminal and respectively to the left and right both sides extend the step clamp arranged, the two side of mounting groove respectively offers the draw-in groove that cooperates with the step clamp, the step clamp is fastened in the draw-in groove, the step clamp can slide up and down in draw-in groove, shell fragment height to metal terminal plays position-limiting action, prevents that metal terminal breaks away from mounting groove.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a decomposing schematic representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1,2, the utility model includes plastic cement pedestal 1, plastic cement pedestal 1 both sides respectively are provided with three mounting grooves 11, be inserted with metal terminal 2 in the mounting groove 11, metal terminal 2 is provided with the contact zone 21 that contacts with SIM card, the tetrapyamid shape structure of contact zone 21 for raising up of metal terminal 2, the top of tetrapyamid shape contact zone 21 is an arc surface 22, each seamed edge of tetrapyamid shape contact zone 21 all is provided with fillet 23, the wearing and tearing when reducing the SIM card insertion.During plug-in card, SIM card all can be inserted from four direction on mobile phone, is not easy wearing and tearing, thereby makes contact more reliable, improved the electric property of product, improved product mechanical endurance, and simplify the structure, reduce stamping procedure, reduce manufacture difficulty, mould molding workpiece handling ease.

The bending downwards of the head front end of metal terminal 2 and respectively to the left and right both sides extend step clamp 24 arranged, the two side of mounting groove 11 respectively offers the draw-in groove 12 that cooperates with step clamp 24, step clamp 24 is fastened in the draw-in groove 12, step clamp 24 can slide up and down in draw-in groove 12, shell fragment height to metal terminal 2 plays position-limiting action, prevents that metal terminal 2 breaks away from mounting groove 11.

Certainly, the above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
