Abstract

An electric connector comprises an insulation body, a shielding shell body which is coated on the peripheral edge of the insulation body and a strengthening cover body which covers on the peripheral side of the insulation body. Among them, the shielding shell body is made out by bending metal plate material. A junction is formed on the bottom surface of the shielding shell body. Two inserting feet are respectively extends downward from the bottom edge of both sides of the strengthening cover body front end. The two inserting feet can be inserted and fixed on a circuit board. By the force of the inserting feet of the strengthening cover body grasping the circuit board, the shielding shell body can be prevented from opening when the connector is inserted in or pulled out.

Description

Electric connector

The relevant a kind of electric connector of the utility model refers to a kind ofly when electric connector plugs especially, prevents the innovation electric connector that shield shell is strutted.

Press, general connector is used to connect two discontinuous cables or discrete circuit is linked together, and is technology well known already, for example general universal serial port connector (USB) in the computer hardware etc. that sees.Above-mentioned electric connector provides a socket to plant to reach the connection of telecommunication for the plug of correspondence; As shown in Figure 1, this connector comprises that an insulating body 1a and is coated on the members such as shield shell 2a of this insulating body 1a periphery, wherein, this shield shell 2a is by a sheet metal bending forming, and the joint of this bending is rabbeted fixing with the dovetail groove seat 20a of both sides mutually, and the root edge of rear end, this shield shell 2a both sides is respectively equipped with an outstanding vertically downward fixing feet 21a, this connector is fixed on the circuit board by this two fixing feet 21a, this shield shell 2a is mainly in order to prevent the interference of electromagnetism, can be used in combining of this socket and this plug (figure slightly), to carry out the transmission of signal.

This connector only utilizes the fixing feet 21a of both sides, this shield shell 2a rear end to be fixed on the circuit board; this shield shell 2a front end does not then have the structure of any fixed support; this connector is non-perpendicular the extracting or inserting because of this plug (figure slightly) in the opening part regular meeting of this shield shell 2a front end; and cause having the generation of oblique angle; this plug (figure slightly) just can produce a torsion and pass to this and shielded body 2a; so when this shield shell 2a bears its torsion or continually under the effect of big strength; making this shield shell 2a front end was that closed joint is strutted into a seam gradually originally; and enlarge and cause the insulating body 1a of this shield shell 2a inside to produce loosening phenomenon; and then influence the stability that plug (figure slightly) is planted; also produce the breach of electromagnetic interference, cause the quality design bad.

As from the foregoing, the shield shell structure of this known connector can't be born bigger and frequent side direction active force, and the situation that causes this shield shell to be strutted takes place, and influence prevents the effect of electromagnetic interference, so on reality is used, obviously have inconvenience and exist, remain to be improved with shortcoming.

The purpose of this utility model is to provide a kind of electric connector, and it can prevent that electric connector from causing this shield shell to be strutted when plug.

According to electric connector of the present utility model, it is characterized in that it comprises:

One insulating body;

One shield shell is coated on the periphery of this insulating body, and this shield shell is bent by metal sheet and forms, and is formed with a joint in this shield shell bottom surface, and these both sides, shield shell rear end are provided with outstanding fixing feet down, and this fixing feet is fixed on the circuit board; And

One strengthens lid, cover is overlying on all sides of this shield shell, appropriate location in this reinforcement lid both sides root edge is respectively equipped with outstanding stator down, and is extended with a pin respectively downwards in this reinforcement lid front end both sides root edge, and this two pin can be pegged graft and is fixed on the circuit board;

Catch the strength of this circuit board by the pin of this reinforcement lid, can prevent that the joint of this shield shell front end from being strutted.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

In the accompanying drawing:

Fig. 1 is the stereo appearance figure of known electric connector.

Fig. 2 is the three-dimensional exploded view of electric connector of the present utility model.

Fig. 3 is the three-dimensional exploded view of electric connector of the present utility model and circuit board.

Fig. 4 is the three-dimensional combination figure of electric connector of the present utility model and circuit board.

Fig. 5 is the front view of electric connector of the present utility model and circuit board.

Please consult Fig. 2 simultaneously to shown in Figure 5, be respectively three-dimensional exploded view, three-dimensional combination figure and the front view of three-dimensional exploded view, electric connector and the circuit board of the utility model electric connector, electric connector provided by the utility model comprises that an insulating body 1, is coated on the shield shell 2 of this insulating body 1 periphery and the members such as reinforcement lid 3 that a cover is overlying on these shield shell 2 all sides, wherein:

This shield shell 2 is a kind of shell that forms that bent by metal sheet, that is, this shield shell 2 includes an end face 20, two bends extension respectively downwards from these end face 20 both sides sidewall 21,22, and make level to extending and hemibase 23,24 close to each other from the root edge of a sidewall 21,22 respectively, and the limit in opposite directions of this two hemibase 23,24 is connected the joint that is a closure, these joint two ends are provided with the fixing dovetail groove seat 25 of mutual interlocking, so form a rectangular section, just can coat this insulating body 1; Moreover, vertical two ends of this shield shell 2 have open front portion and the after-opening portion that communicates with each other, the periphery of this open front portion is provided with the outer antelabium 26 that lifts, this antelabium 26 imports when planting and uses for plug (figure slightly), the longitudinal length of the hemibase 23,24 of this shield shell 2 is about half of this end face 20, and near this open front portion, again, the second half section place of the sidewall 21,22 of this shield shell 2 and nearly after-opening portion is provided with several outstanding fixing feet 27 down, and these fixing feet 27 are fixedly welded on the circuit board 3.

This reinforcement lid 3 is one to be the shell of  shape, appropriate location in these reinforcement lid 3 both sides root edges is respectively equipped with outstanding stator 30 down, stator 30 is after these reinforcement lid 3 covers cover in conjunction with this shield shell 2, bend inwards and closely fix this reinforcement lid 3 and this shield shell 2, moreover, respectively be provided with a pin 31 that extends downwards in these reinforcement lid 3 front end both sides root edges, this two pin 31 is pegged graft respectively corresponding in the jack on this circuit board 4 40 and fix, also available welding or adhesion system make it fixing more firm.

In view of the above, this shield shell 2 is caught the strength of circuit board 4 by the pin 31 of this reinforcement lid 3, prevents the phenomenon that electric connector causes the joint at these shield shell 2 preceding half section places to be strutted when plug.

In sum, the utility model has improved the known electric connector shortcoming that the shield shell that causes is strutted when plug, and it is rare novel product, has novelty and creativeness, meet the utility application condition fully, so propose patent application according to Patent Law.

Only the above only is a preferable possible embodiments of the present utility model, and non-so promptly inflexible limit claim of the present utility model so the equivalent structure that uses the utility model specification and accompanying drawing content to be done such as changes, all should be contained in the scope of the present utility model.
