Description

TECHNICAL FIELD

[0001] The present invention relates to an electrical connector assembly, and more particularly to an electrical connector assembly capable of stable contact.

BACKGROUND

[0002] A Chinese patent with patent number CN200380108240.3 discloses an electrical connector assembly matable with a complementarily mating connector. The electrical connector assembly terminates two pairs of signal lines or conductors, which are terminated to respective terminals that are electrically connected to two pairs of signal terminals in the mating connector. The electrical connector assembly also terminates a pair of power lines or conductors, which are terminated to respective terminals in the electrical connector assembly and are electrically connected to a pair of power terminals mounted in the mating connector. The connector assembly includes a dielectric composition housing defined by a pair of interconnectable housing members. Each housing member mounts respective terminals for termination to one of the pair of signal lines and one of the pair of power lines. Although each housing member has a pair of openings on opposite sides of the respective terminals for locking tabs of the other housing member positioned on the opposite sides of the terminals, the electrical connector has the following problems:

[0003] (1) When the electrical connector assembly mates with the complementarily mating connector, the dielectric composition housing is only the cylindrical portion inserted into the mating cavity of the complementarily mating connector. Since the cylindrical portion of the dielectric composition housing is weak in strength and easy to deform, when the signal lines or the power lines are subjected to a pulling force in a non-horizontal direction, the signal lines or the power lines are bent and generate a force on the dielectric composition housing, which causes the dielectric composition housing to be deflected and disengaged from the complementarily mating connector, so that the electrical connection between the electrical connector assembly and the complementarily mating connector is unstable.

[0004] (2) Since the dielectric composition housing is defined by a pair of interconnectable housing members, the two housing members are engaged with the locking tabs of the other housing member through the pair of openings of the housing members. When the electrical connector assembly mates with the complementarily mating connector, the signal lines or the power lines are pulled downward for adjusting the arrangement of the signal lines or the power lines, or the electrical connector assembly is separated from the complementarily mating connector by an irregular operation of pulling the signal lines or the power lines downward on the lower housing member. Since the signal lines or the power lines on the lower housing member are subjected to a downward pulling force, the signal lines or the power lines are bent and generate a downward force on the lower housing member, which easily causes the lower housing member to be disengaged downward from the upper housing member.

[0005] Therefore, it is necessary to design an improved electrical connector assembly to overcome the above problems.

[0041] As Figure 8As shown, the second body 22 is provided with a first part 221 and a second part 222 above the first part 221 and connected to the first part 221. The first part 221 houses a plurality of second terminals S, the second terminals S are connected to the second wires L2, in the embodiment, the second terminals S are signal terminals, the second terminals S are arranged in a row along the left-right direction, the second wires L2 are signal wires, and the second wires L2 are thinner than the first wires L1. The portion a of the first part 221 protruding forward beyond the second part 222 is provided with a plurality of through grooves 2211 for accommodating the second wires L2, the through grooves 2211 penetrate the first part 221 upwardly, and the through grooves 2211 are below the bottom surface of the base 211 so that the bottom surface of the base 211 covers the through grooves 2211. The first part 221 is provided with a plug-in part b protruding rearward beyond the second part 222, and the plug-in part b is used for plugging into the second counterpart body 11B. The front side of the second part 222 is provided with two first protrusions e and a plurality of second protrusions f, and the two first protrusions e are located on the left and right sides of the plurality of second protrusions f, and the positions of the first protrusions e are higher than those of the second protrusions f.

[0042] The second part 222 enters the insertion groove 2111, and the first part 221 is located outside the insertion groove 2111. The bottom surface of the second part 222 has two blocking parts 2221 protruding beyond the left and right sides of the first part 221 along the left-right direction, and the third stop part 133 is stopped by the blocking parts 2221 to limit the downward movement of the second body 22. The second part 222 is provided with a plurality of accommodation grooves 2220 for accommodating the first terminals P, and the accommodation grooves 2220 are surrounded by a top part c and a bottom part d arranged oppositely upward and downward and two side parts g connecting the top part c and the bottom part d. The bottom part d is located above the second terminals S to limit the upward movement of the second terminals S, and the bottom part d is located behind the through grooves 2211. The second terminals S have wire clamping parts S1 for clamping the second wires L2, and the wire clamping parts S1 are covered by the bottom part d. The top part c and the bottom part d are integrally formed with a plurality of protrusions 2224 respectively to limit the forward movement of the first terminals P out of the first body 21. The top part c and the bottom part d are respectively provided with a plurality of recesses 2222, and the front surfaces of the recesses 2222 are used to limit the forward movement of the first terminals P.

And since the protrusion 2224 is located between the two recesses 2222, the left and right surfaces of the protrusion 2224 limit the left and right movement of the protrusion P1. Figure 11 As shown, the protrusion 2224 is located in front of the stop portion P2, so that the protrusion 2224 limits the forward movement of the stop portion P2.

[0044] The first and second wires L1 and L2 are easy to bend under force, and when the first and second wires L1 and L2 are bent, an acting force is generated on the second connector 2. By providing the first, second and third stop portions 131, 132 and 133 on the first connector 1, the acting force is prevented from causing the second connector 2 to deflect and come out of the first connector 1, the fixing effect of the first connector 1 on the second connector 2 is enhanced, and the contact between the first and second connectors 1 and 2 is stable. Figure 2 And Figure 3 As shown, when the first and second connectors 1 and 2 are connected, the base 211 is at least partially located between the two first stop portions 131, so that the two first stop portions 131 limit the left and right movement of the base 211, the base 211 is at least partially located between the second and third stop portions 132 and 133, so that the second and third stop portions 132 and 133 limit the up and down movement of the base 211, and the second body 22 is located above the third stop portion 133, so that the third stop portion 133 limits the downward movement of the second body 22.

[0045] The electric connector combination 100 of the embodiment is assembled as follows: first, the two first protrusions e are fitted into the two first recesses 2115, so that the bottom surface of the first recess 2115 prevents the first protrusion e from moving downward, and the second part 222 is positioned in the insertion slot 2111; then, after the first terminal P is assembled into the first body 21 and the second terminal S is assembled into the second body 22, the first part 221 is pressed upward, the second protrusions f are fitted into the second recesses 2116, and the bottom surface of the second recess 2116 prevents the second protrusion f from moving downward, so that the second part 222 is finally positioned in the insertion slot 2111; finally, the column 212 is inserted into the first mating body 11A, and the second body 22 is inserted into the second mating body 11B, until the rear end surface of the base 211 abuts against the front end surface of the insulating body 11, the locking arm 2114 is engaged with the locking block 14, the first stop part 131 and the second stop part 132 are inserted into the receiving slot 2112, and the third stop part 133 is located below the blocked part 2221, thereby completing the mating of the electric connector combination 100.

[0046] Figures 12-14 The second embodiment of the electric connector combination 100 of the present application is provided.

[0047] The difference between the embodiment and the first embodiment is that the limiting frame 13 is integrally formed with the insulating body 11, the insulating body 11 does not need to be additionally provided with the limiting slot 111 and the stop slot 112 for fixing the limiting frame 13, and the front end of the base 211 is not provided with the receiving slot 2112 for receiving the first stop part 131 and the second stop part 132, and when the first connector 1 and the second connector 2 are mated, the first stop part 131, the second stop part 132, and the third stop part 133 are located outside the base 211. The rest of the structure of the second embodiment is the same as that of the first embodiment, and thus will not be described again.

[0048] The electric connector combination 100 of the present application has the following beneficial effects:

[0049] 1. When the first connector 1 and the second connector 2 are mated, the base 211 is located between the two first stop portions 131, so that the two first stop portions 131 limit the left and right movement of the base 211, the base 211 is located between the second stop portion 132 and the third stop portion 133, so that the second stop portion 132 and the third stop portion 133 limit the up and down movement of the base 211, and the second body 22 is located above the third stop portion 133, so that the third stop portion 133 limits the downward movement of the second body 22. The first connector 1 is fixed to the second connector 2 through the first stop portion 131, the second stop portion 132 and the third stop portion 133, so as to avoid the deflection of the second connector 2 caused by the force generated when the second connector 2 is bent in a non-horizontal direction of the first wire L1 and the second wire L2, and to stabilize the contact between the first connector 1 and the second connector 2.

[0050] 2. After the first connector 1 and the second connector 2 are matched, when the second wire L2 is subjected to a downward pulling force, the second body 22 is also subjected to a downward pulling force, but since the second body 22 is located above the third stop portion 133, the third stop portion 133 can further limit the downward movement of the second body 22, prevent the second body 22 from being fixed unstably only by the second protrusion f and the insertion slot 2111, and then the second body 22 is pulled out of the insertion slot 2111, so as to stabilize the fixation of the second body 22.

[0051] 3. In the second embodiment, the limiting frame 13 is integrally formed with the insulating body 11, the limiting frame 13 is simple to form and is not easy to deform, and the limiting effect is more stable. The insulating body 11 does not need to be additionally provided with the limiting slot 111 and the stop slot 112 for fixing the limiting frame 13, the structure of the insulating body 11 is simple, and the manufacturing is simple. The front end of the base 211 is not provided with the receiving slot 2112 for receiving the first stop portion 131 and the second stop portion 132, when the first connector 1 and the second connector 2 are mated, the first stop portion 131, the second stop portion 132 and the third stop portion 133 are located outside the base 211, the structure of the base 211 is simple, and the forming is more simple.
