Edge material is made, and is welded and fixed to circuit board after being fixed with multiple conductive terminals for contacting with electronic card thereon, described
Shielding casing is generally made of metal material, and mask is above the pedestal and is soldered to circuit board, the shielding casing and institute
State the accommodating space being collectively formed between pedestal for accommodating electronic card；For the ease of being inserted and removed from electronic card, the card connects
Connect device generally and further include the Kato for carrying electronic card to be inserted into the accommodating space, in order to further decrease manufacture at
This, existing Kato on the market mostly uses greatly metal outsourcing insulated plastic to be made, but Kato is being inserted into or is exiting the receiving sky
When interior, the sliding friction of Kato can generate electrostatic, and due to the overmolded insulated plastic in Kato outer surface, electrostatic without
Method is connected to shielding casing ground connection by Kato and is guided, so as to cause short circuit occurs between each conductive terminal, so that damaging the card
Connector.
Therefore, it is necessary to design the new card connector of one kind to solve the above problems.
Summary of the invention
In order to overcome shortcoming and defect existing in the prior art, the purpose of this utility model is to provide a kind of connections of card
Device, the electrostatic damage card connector that Kato sliding friction can be effectively prevent to generate.
To achieve the above object, the utility model uses following technical scheme:
A kind of card connector characterized by comprising the metal-back of insulating base frame and mask above the insulating base frame
Body is fixed with multiple conductive terminals on the insulating base frame, receiving is formed between the metal shell and the insulating base frame
Space, multiple conductive terminals have the multiple contact portions being exposed in the accommodating space；It further include Kato, the Kato
For carrying electronic card to be inserted into the accommodating space, the Kato includes that plastic frame body and edge bury and take shape in the plastic cement
The intracorporal metalwork of frame, the plastic frame body is made of conductive plastic material or the plastic frame body surface is covered with conductive film
Layer, when the Kato is inserted into the accommodating space, the plastic frame body is in contact with the metal shell.
In one embodiment, the conductive film layer is plated on the plastic frame body surface.
In another embodiment, the conductive film layer is sprayed at the plastic frame body surface.
Further, the plastic frame body is in contact with the inner wall of the metal shell.
Compared with prior art, the utility model has the following beneficial effects:
The card can be effectively ensured by the way that Kato is designed to that metal outsourcing plastic cement is made in the utility model card connector
The structural strength of support, and manufacturing cost can be reduced, and the plastic frame body is made of conductive plastic material or the plastic frame
Body surface face is covered with conductive film layer, when in the accommodating space that the Kato is inserted into the card connector, the plastic frame body
It is in contact with the metal shell, so that the electrostatic that the Kato generates in swapping process is connected to metal shell and is grounded
It guides, prevents card connector described in electrostatic damage, structure is simple, and manufacture is easy.
Detailed description of the invention
Fig. 1 is the Three-dimensional combination diagram of the utility model card connector；
Fig. 2 is the decomposition diagram of the utility model card connector；
Fig. 3 is the decomposition diagram of the Kato of the utility model card connector.
The drawing reference numeral of specific embodiment illustrates:
| Insulating base frame 1 | Circuit board 10 | Conductive terminal 11 | Contact portion 111 |
| Metal shell 2 | Kato 3 | Plastic frame body 31 | Metalwork 32 |
Specific embodiment
For convenient for better understanding the purpose, structure, characteristics and efficacy of the utility model, now in conjunction with attached drawing and specific
The utility model is described in further detail for embodiment.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, the utility model discloses a kind of card connectors, the electricity for being soldered in mobile phone
On road plate 10, metal shell 2 including insulating base frame 1 and mask above the insulating base frame 1 is solid on the insulating base frame 1
Surely there are multiple conductive terminals 11, be formed with accommodating space between the metal shell 2 and the insulating base frame 1, it is multiple described to lead
Electric terminal 11 has multiple contact portions 111 for being exposed in the accommodating space, the contact portion 111 be used for be inserted into it is described
Electronic card in accommodating space is in contact；It further include Kato 3, the Kato 3 is for carrying electronic card to be inserted into the receiving
In space, the Kato 3 includes that plastic frame body 31 and edge bury and take shape in the intracorporal metalwork 32 of the plastic frame, the plastic frame
Body 31 is made of conductive plastic material, when the Kato 3 is inserted into the accommodating space, the plastic frame body 31 with it is described
Metal shell 2 is in contact.
Specifically, when the Kato 3 carrying electronic card is inserted into the accommodating space, multiple conductive terminals 11
Multiple contact portions 111 contacted respectively with the golden finger of the electronic card, to the electronic card be connected to circuit board 10, together
When, the plastic frame body 31 is in contact with the inner wall of the metal shell 2, so that the Kato 3 be produced in swapping process
Raw electrostatic is connected to metal shell 2 and is grounded and guides, and prevents card connector described in electrostatic damage；Certainly in other embodiments
