Abstract

The utility model relates to a connector with a short circuit protection structure, which is provided with an insulating base and an outer shell, wherein the outer shell is covered on the circumference of the insulating base which is provided with a main body, and the main body is provided with a forward extending tongue sheet with a plurality of terminals. After extend backward and pass through a channel of the main body, the terminals on the tongue sheet turn downward to penetrate a fixed slot in a square tooth block which protrudes backward at the near lower part of the main body. On the rear end face of the main body of the insulating base, both corresponding sides of the square tooth block are respectively provided with a lug; the length of each lug can be equal to or slightly greater than that of the tooth of a main tooth block; the back lower end of the downward folded top surface of the outer shell is pressed on the back surfaces of the two lugs; the back side of the outer shell is sealed to prevent electromagnetic interference and short circuit phenomenon caused by the contact of the terminals and the outer shell.

Description

Connector with anti-short-circuit structure

The utility model relates to a kind of connector with anti-short-circuit structure, refers in particular to have to be arranged at the connector back and to make shell can not produce the connector of contacting structure with terminal.

Traditional connector, as shown in Figure 6, it is not provided with capping face on the rear end face of shell 4, be to be a saturating empty structure, and upper and lower both sides, the rear end of insulating base 5 form the

projection

51,52 of symmetry, in order to forming the high space of frame, allowing each terminal 6 pass through, and allow each terminal 6 be clamped in roller seating space 53 places of projection 52 down.The last projection 51 that is provided with on this structure is unnecessary, and the essence effect is little, and shell do not add the back, just can not increase the performance that prevents electromagnetic interference, is that the utility model and improvement design are arranged.

The purpose of this utility model is to provide a kind of connector with anti-short-circuit structure, its cancellation is located at the last projection of insulating base top originally, square gear block two outside portions that slightly enlarge terminal fixing on the insulating base are divided into projection, allow the back of shell be abutted against, with the wider space of built on stilts terminal, and on the back of shell end directly and end face join and form, directly bear bending with broken line, need not against, to save segment space.Insulating base structure therefore of the present utility model is simpler, is easier to make.

Connector with anti-short-circuit structure provided by the utility model has an insulating base and a shell, shell is coated on around the insulating base, insulating base has a main body, main body has one to protract and contain the tongue piece of several terminals, after each terminal on the tongue piece extends back and passes through the perforation conduit in the main body, turnover is passed down through the fixing groove in the rearwardly projecting square gear block in the nearly lower end of main body, it is characterized in that: at the rear end face of this insulating base main body, corresponding both sides in the position of square gear block, respectively be provided with a projection, make the length of projection can be with the tooth of square gear block isometric or slightly long, allow be crimped on the rear surface of two projections the lower end, back of folding down, in order to allow the capping of shell back prevent that electromagnetic interference from not producing short circuit phenomenon with not making terminal and housing contacts by outer casing top surface.

The following stated is explanation of the present utility model and accompanying drawing, is not to be used for the utility model is limited, and relevant accompanying drawing is:

Fig. 1 is a back of the body parallax stereogram of the present utility model.

Fig. 2 is a front perspective view of the present utility model.

Fig. 3 is a three-dimensional exploded view of the present utility model.

Fig. 4 is a bottom view of the present utility model.

Fig. 5 is another enforcement bottom view of the utility model.

Fig. 6 is the stereogram of traditional connector.

Fig. 1 is to Figure 5 shows that a kind of connector with anti-short-circuit structure of the utility model, have an insulating base 2 and a shell 1, this shell 1 is coated on around the insulating base 2, shell 1 is provided with a top side (narrow) face 11, be connected in a left side (wide) face 12 and right side (wide) face 13 of top side face 11 both sides, be connected in a trailing flank 14 of top side face 11 back side edge, at left surface 12, right flank 13 another sides respectively are provided with left half bottom side 16, right half bottom side 17, make this two

halves bottom side

16,17 limit in opposite directions overlaps mutually, this insulating base 2 contains a main body 20, main body 20 contains one and protracts and contain the tongue piece 21 of several terminals 3, after each terminal 3 on the tongue piece 21 extends back respectively and passes through each the corresponding through slot road 22 in the main body 20, terminal 3 turnovers are passed down through each the corresponding fixing groove 24 in the rearwardly projecting square gear block 23 in main body 20 nearly lower ends, end face after these insulating base 2 main bodys 20, corresponding two sides in the position of square gear block 23, respectively be provided with a projection 25, allow the length of each projection 25 or omit length (as shown in Figure 5 with the tooth of square gear block 23 isometric (shown in Figure 4), at this moment a high space 26 is arranged) between the increment face of tooth piece 23 and shell back, allow trailing flank 14 lower ends of rolling over for 11 times be crimped on the surface of two projections 25, produce the phenomenon of short circuit to prevent electromagnetic interference with not making terminal and housing contacts in order to allow shell 1 back have capping by shell 1 end face.Wherein these trailing flank 14 dual-sides each forward the folding be provided with an auricle 141, be provided with a slotted eye 142 on each auricle 141 at least, corresponding shell two

sides

12,13 set tabs 121,131 can be buckled in the slotted eye 142.

Structure in sum, the trailing flank of the utility model utilization shell is placed on the place, back of insulating base, only section acts on the frame height that square gear block and a pair of projection reach the shell back under insulating base, reach the clamping and the location of the left and right sides again with the auricle of both sides, in order to moving of preventing that the shell back from being produced, also can make to have capping behind the shell and do not produce the phenomenon of short circuit with not making terminal and housing contacts to prevent electromagnetic interference; The more important thing is, insulating base upper end need not to be provided with square gear block isometric hold piece, increase the inner space, promptly prevent moving mutually between two elements shell and insulating base fully, reach the function that the location holds.Thereby directly use the structure of improvement, finish the function of assembling, need not to implement again other fabrication schedule, realize more convenient and automatic modularity winding.

The above is the detailed description and the diagram of preferred embodiment of the present utility model, be not to be used for limiting the utility model, all scopes of the present utility model should be as the criterion with following claim, the embodiment and the approximate construction of all and claim restricted portion and spirit and similar variation thereof all should be contained among the utility model.
