a housing having a plurality of terminal receiving grooves which extend forwardly from a rear end face of the housing and receive the conductive terminals respectively and a locking structure which is formed to a top surface of the housing, each terminal receiving groove having an upper inner wall face, a lower inner wall face, a slope which is formed to the upper inner wall face and obliquely extends downwardly and forwardly from a position adjacent to the rear end face of the housing and a receiving recessed portion which is formed to the lower inner wall face and receives the corresponding conductive terminal; and
a holder provided to the housing, the holder having a transverse frame portion which extends in a transverse direction, a plurality of positioning arms which obliquely extend downwardly and forwardly from the transverse frame portion and are respectively inserted into the terminal receiving grooves and a lock plate portion which extends forwardly from a top of the transverse frame portion to above a top surface of the housing and has elasticity, each positioning arm having a first oblique segment which is close to the transverse frame portion and a second oblique segment which is connected to the first oblique segment and is away from the transverse frame portion, an angle of obliqueness of the second oblique segment being larger than an angle of obliqueness of the first oblique segment, the corresponding slope guiding the positioning arm to make a front end of the second oblique segment position the corresponding conductive terminal, and the front end face of the insulating portion of the corresponding cable being positioned at the first oblique segment, the lock plate portion being formed with a lock structure which is locked with the locking structure of the housing.

2. The electrical connector according to claim 1 , wherein the terminal receiving grooves are arranged side by side along a direction, the transverse frame portion extends along the direction.

3. The electrical connector according to claim 2 , wherein the terminal receiving grooves are a plurality of first terminal receiving grooves, the locking structure is a first locking structure, the housing further has a plurality of second terminal receiving grooves which are arranged side by side along the direction, extend forwardly from the rear end face of the housing and are positioned below the first terminal receiving grooves and a second locking structure which is formed to a bottom surface of the housing, the first terminal receiving grooves receive one part of the conductive terminals, the second terminal receiving grooves receive the other part of the conductive terminals, each second terminal receiving groove has a lower inner wall face, an upper inner wall face, a slope which is formed to the lower inner wall face and obliquely extends upwardly and forwardly from a position adjacent to the rear end face of the housing and a receiving recessed portion which is formed to the upper inner wall face and receives the corresponding conductive terminal, the electrical connector further comprises another holder, the positioning arms of the another holder respectively obliquely extend upwardly and forwardly and are inserted into the second terminal receiving grooves respectively, a lock plate portion of the another holder extends forwardly to below a bottom surface of the housing and has elasticity, the corresponding slope of the second terminal receiving groove guides the positioning arm of the another holder to make a front end of a second oblique segment of the positioning arm of the another holder position the corresponding conductive terminal, and the front end face of the insulating portion of the corresponding cable is positioned at a first oblique segment of the positioning arm of the another holder, a lock structure of the another lock plate portion is locked with the second locking structure.

4. The electrical connector according to claim 1 , wherein the lock structure of the lock plate portion and the locking structure of the housing are locked with each other in a concave convex fit.

5. The electrical connector according to claim 4 , wherein the locking structure of the housing comprises at least one latch protruding block, the lock plate portion of the holder extends transversely, and the lock structure of the lock plate portion has at least one latch hole which is engaged with the at least one latch protruding block.

6. The electrical connector according to claim 5 , wherein the at least one latch hole is formed to penetrate the lock plate portion.

7. The electrical connector according to claim 1 , wherein the holder further has a plurality of inward recessed faces which are respectively formed to the positioning arms and respectively face the conductive terminals, the inward recessed faces respectively are arch surfaces which are recessed inwardly toward a direction away from the conductive terminals, and the inward recessed faces respectively extend from the positioning arms to the transverse frame portion.

8. The electrical connector according to claim 1 , wherein each conductive terminal is formed with a positioning protrusion, each terminal receiving groove further has a stopping face, the front end of the second oblique segment of the positioning arm pushes the positioning protrusion of the corresponding conductive terminal forwardly to the corresponding stopping face to position the corresponding conductive terminal.

9. The electrical connector according to claim 1 , wherein a front end face of the transverse frame portion of the holder abuts the rear end face of the housing.

10. The electrical connector according to claim 1 , wherein the front end faces of the insulating portions of the cables respectively abut the first oblique segments.

11.
