Embodiment

As shown in Figure 1 to Figure 3, cable connector 20 structures of the present utility model include: a body 21, and a metal shell; Wherein:

This body 21 is provided with plural number and connects terminal 211, respectively connect terminal 211 and partly expose to this body 21 tops, and part is located in the body 21, and these body 21 tops also are formed with a grafting space 212 for plugging coupling with another aerial lug, these 212 places, body grafting space are provided with at least one elongated that runs through upper and lower surface and wear groove 213, and the peripheral region in this body grafting space 212 is provided with at least one slot 214 and barricade 215;

This metal shell is fixed on this body 21, and be provided with procapsid 22 and back casing 23, before being somebody's turn to do,

back casing

22,23 with these body 21 1 sides and be formed with and insert mouthfuls 24, this insertion mouthfuls 24 also connects terminal 211 with this and communicates, this procapsid 22 extends to form first by body 21 belows along body 21 at least one sidewalls and coats arm 221 towards body 21 tops, and this first coating arm 221 also forms the slotting portion 222 of falling that can stretch in the body 21, and this back casing 23 extends to form second by body 21 belows along body 21 at least one sidewalls and coats arm 231 towards body 21 tops, and this back casing 23 and be formed with the registration arm 232 that can interfere the location with these body 21 sidewalls.

This procapsid 22 promptly utilizes each first coating arm 221 to coat these bodies 21 by this body below, and among the embodiment as shown in the figure, each first cladding 221 can be coated on respectively on four side arms of body 21, part is fallen to insert portion 222 and can be planted respectively and is positioned in the slot 214, the slotting portion 222 of part then coating is positioned on the barricade 215, and coating is positioned the coating of first on the barricade 215 arm 222 and is formed with portion of class 223 near falling to insert portion 222 places, please consult shown in Figure 4 simultaneously, increase the elasticity of the first coating arm 222 by this portion of class 223, procapsid 22 is engaged really with body 21, and back casing 23 coats these bodies 21 by these body 21 belows by each second coating arm 231 equally, and this second coating arm 231 can be coated on respectively on three side arms of body 21, wherein these body 21 both sides sidewalls are provided with groove 216 for these registration arm 232 interference location, as Fig. 5 and shown in Figure 6, back casing 23 is engaged really with body 21, can limit body 21 and metal shell 22 relative displacements, and then formation body 21 combines with the firm of metal shell 22.
