Abstract
The utility model discloses a grounding device of an electrical connector with a USB connector, which comprises a plastic body of the electrical connector, one or more than one connecting terminal structures arranged in the plastic body, and a metal shell matched with the plastic body, wherein openings are arranged on the metal shell corresponding to the connecting terminal structures, and a grounding device is arranged at the opening of the metal shell corresponding to the connecting terminal structure; and the grounding device and the metal shell are integrally formed, and the grounding device is of an elastic piece which tilts away from the direction of the plastic body from the corner of the opening of the metal shell corresponding to the connecting terminal structure. Compared with the prior art, the elastic piece for grounding and the metal shell are integrally formed by stamping, and the processing is convenient; the elastic piece which is arranged at the four corners is propped against the gap of the USB metal terminal structure and is directly contacted with the terminal structure, so the grounding effect is good, and the use is reliable.
Description
Technical field
The utility model relates to a kind of earthing device of electric connector, especially relates to a kind of earthing device of electric connector of USB joint.
Background technology
Existing electric connector, include the plastic cement body, be arranged at the metal terminal structure in the plastic cement body, and the metal shell that cooperates with the plastic cement body, metal shell mainly shields and the ground connection effect, general electricity connects the device joint, comprise the USB joint, when terminal structure is done the ground connection processing, in general, be metal shell, and lead is realized with terminal structure and with being connected by welding of metal shell a lead one another termination electric connector of termination end minor structure.Because the space is limited, adds the installation procedure complexity simultaneously, welding this process will increase cost of processing and difficulty, if the unreliable increase that also can cause defective products of welding; And service time long after, might cause the plumb joint place insecure, thereby earthing failure causes the use of USB joint no longer reliable.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of earthing device that uses the band USB interface electric connector reliable, easy to process, that cost is low is provided.
For achieving the above object, the utility model has adopted following technical proposals:
This electric connector that contains the USB joint that has earthing device, the plastic cement body that comprises electric connector, be arranged at the one or more splicing ear structure in the plastic cement body, and the metal shell that cooperates with the plastic cement body, corresponding splicing ear structure place all is provided with opening on the metal shell, opening part in the corresponding USB splicing ear of described metal shell structure is provided with and the integrated earthing device of metal shell, and described earthing device is to the shell fragment away from the direction perk of plastic cement body from the edge of the opening part of the corresponding USB splicing ear structure of metal shell.
Described shell fragment is arranged at the combination of any two jiaos of triangles in a jiao or four jiaos of opening.
The metal shell of the shell fragment of described edge and USB splicing ear structure connects.
The breach butt of the metal shell edge of described shell fragment and USB splicing ear structure.
Described shell fragment is consistent with the adjacent side height that the metal shell of USB splicing ear forms breach to the height away from the perk of plastic cement body direction.
By technique scheme, thereby this utility model has following beneficial effect:
1. shell fragment and the moulding of metal shell integrated punching are easy to process;
2. shell fragment is arranged at four jiaos of openings, connects with the indentation, there of USB metal terminal structure, directly contacts with terminal structure, and ground connection is effective, uses reliable.
Description of drawings
Fig. 1 is the three-dimensional assembly diagram of the earthing device of the utility model band USB joint electric connector.
Fig. 2 is the stereogram of the earthing device of the utility model band USB joint electric connector.
Embodiment
Below in conjunction with accompanying drawing the utility model is made further instruction.
As Fig. 1, shown in Figure 2, this electric connector that contains the USB joint that has earthing device, the plastic cement body 1 that comprises electric connector, be arranged at the one or more splicing ear structure 2 in the plastic cement body, and the metal shell 3 that cooperates with the plastic cement body, corresponding splicing ear structure place all is provided with opening 4 on the metal shell, opening part in the corresponding USB splicing ear of described metal shell structure is provided with and the integrated earthing device of metal shell, and described earthing device is to the shell fragment 5 away from the direction perk of plastic cement body from the edge of the opening part of the corresponding USB splicing ear structure of metal shell; Described shell fragment is arranged at four jiaos of opening, and connect with the metal shell of USB splicing ear structure, the butt place is the breach of the metal shell edge of USB splicing ear structure, after the butt directly and the metal part branch of terminal structure join, in use reach shielding, prevent effect such as static.
Specifically, described shell fragment is to consistent with the adjacent side height that the metal shell of USB splicing ear forms breach away from the height of plastic cement body direction perk, from and don't can have influence on the use of metal shell body.
Compared with prior art, be used for shell fragment and the moulding of metal shell integrated punching of ground connection, easy to process; Shell fragment is arranged at four jiaos of indentation, there with USB metal terminal structure of opening and connects, and directly contacts with terminal structure, and earthing effect is good, uses reliable.
Certainly, on described shell fragment also can only be arranged at wherein one jiao, perhaps on any two jiaos, perhaps arbitrarily on the triangle, all belong to protection domain of the present utility model.
Claims (5)
1. earthing device with USB joint electric connector, the plastic cement body that comprises electric connector, be arranged at the one or more splicing ear structure in the plastic cement body, and the metal shell that cooperates with the plastic cement body, corresponding splicing ear structure place all is provided with opening on the metal shell, it is characterized in that: the opening part in the corresponding USB splicing ear of described metal shell structure is provided with and the integrated earthing device of metal shell, and described earthing device is to the shell fragment away from the direction perk of plastic cement body from the edge of the opening part of the corresponding USB splicing ear structure of metal shell.
2. the earthing device of band as claimed in claim 1 USB joint electric connector is characterized in that: described shell fragment is arranged at the combination of any two jiaos of triangles in a jiao of opening or the angle.
3. the earthing device of band USB joint electric connector as claimed in claim 1 or 2, it is characterized in that: the metal shell of the shell fragment of described edge and USB splicing ear structure connects.
4. the earthing device of band USB joint electric connector as claimed in claim 3 is characterized in that: the breach butt of the metal shell edge of described shell fragment and USB splicing ear structure.
5. the earthing device of band USB joint electric connector as claimed in claim 4 is characterized in that: described shell fragment is consistent with the adjacent side height that the metal shell of USB splicing ear forms breach to the height away from the perk of plastic cement body direction.
