Description

Technical field

[0001] The utility model relates to an electric connector, in particular to an electric connector with stable contact and high assembly efficiency. [Background Technology]

[0002] An existing electrical connector includes an insulating body, a terminal module housed in the insulating body, and a grounding member. The terminal module includes a plurality of signal terminals and a plurality of grounding terminals arranged along a first direction. Each signal terminal and each grounding terminal has a contact portion, a conductive portion, and an intermediate portion connected to the contact portion and the conductive portion. The grounding terminal includes a plurality of clamping arms extending from the intermediate portion. The clamping arms are hook-shaped and extend backward and upward from the intermediate portion of the grounding terminal. A gap is formed between the clamping arms and the intermediate portion in the front-to-back direction. The grounding member is stamped from a metal plate and has a flat A plate-shaped main body and an extension portion bent and connected to one end of the main body, the main body and the extension portion are roughly L-shaped, and the main body is provided with a plurality of slits extending in the up-down direction and passing through the main body front and back; during installation, the grounding piece is moved forward in the front-to-back direction to the rear of the insulating body, and the clamping arm is passed through the corresponding slit backward in the front-to-back direction, and then the grounding piece is moved downward in the up-down direction, so that the main body is clamped downward into the gap between the clamping arm and the middle portion of the corresponding grounding terminal, and then the main body is clamped in the front-to-back direction by the clamping arm and the middle portion of the corresponding grounding terminal, thereby completing the fixation of the two.

[0003] The assembly process of the grounding member of the above-mentioned electrical connector is complicated. It requires simultaneous assembly of both sides of the insulating body, namely, the main body located on the rear side of the insulating body and the clamping arm, and the top of the insulating body and the extension. Such installation is relatively complicated and requires a high degree of precision, which is not convenient for automated operation and has low assembly efficiency. Moreover, the multiple clamping arms of each grounding terminal only support the grounding member upward and limit the grounding member in the front-to-back direction. Therefore, during the movement of the electrical connector, this contact method easily causes the grounding member to deviate, resulting in unstable contact between the two. In the production process of the grounding member, it is necessary to first blank and punch the metal sheet to form the slits, and then stamp the grounding member to bend it. Such a configuration is relatively complicated and costly.

[0004] Therefore, it is necessary to provide an electrical connector with stable contact and high assembly efficiency to overcome the above-mentioned defects. [Utility Model Content]

Specifically, the first clamping arm 32a acts on the clamping hole 36 to the left, and the second clamping arm 32b acts on the clamping hole 36 to the right.

[0064] like Figure 6 and Figure 7 As shown, in the first embodiment, one of the first holding arm 32a and the second holding arm 32b is clamped in one of the holding holes 36, that is, the first holding arm 32a acts on the left side of the corresponding holding hole 36, and the second holding arm 32b acts on the right side of the corresponding holding hole 36. Figure 14 and Figure 15As shown, in the second embodiment, one clamping hole 36 simultaneously clamps both one first clamping arm 32a and one second clamping arm 32b, that is, for the same clamping hole 36, the first clamping arm 32a acts on its left side, and the second clamping arm 32b acts on its right side.

[0065] like Figure 6 and Figure 7 As shown, in either of the two aforementioned embodiments, the first latching hole 37 and the second latching hole 38, located in the middle of the second shielding member 3b and opposite to each other in the vertical direction Z, are interconnected. The first latching arm 24a and the second latching arm 24b, located in the middle of the connecting portion 232 of each grounding terminal G, are engaged with the hole connecting the first latching hole 37 and the second latching hole 38, and the first latching arm 24a and the second latching arm 24b act in opposite directions on the second shielding member 3b in the vertical direction Z. Specifically, the first latching arm 24a is engaged with the lower side of the first latching hole 37, and the second latching arm 34b is engaged with the upper side of the second latching hole 38. In the first embodiment, the first latching hole 37 at the top of the second shielding member 3b is interconnected with one of the corresponding latching holes 36 in the vertical direction Z. In the second embodiment, the second latching hole 38 at the bottom of the second shielding member 3b extends downward through the second shielding member 3b.

[0066] like Figure 1 、 Figure 4 and Figure 6 As shown, in the first embodiment, the second shielding member 3b also includes a plurality of pins 39, each of the pins 39 corresponds to one of the grounding terminals G, and the plurality of pins 39 are soldered on the circuit board 300. Specifically, each of the pins 39 and the conductive portion 22 of the corresponding grounding terminal G are soldered on the same pad of the circuit board 300.

[0067] It can be understood that in other embodiments, the first shielding member 3a and the second shielding member 3b can be interchanged, that is, one of the first shielding member 3a and the second shielding member 3b is provided with the first clamping arm 32a and the second clamping arm 32b, and the other is provided with the clamping hole 36 corresponding to the first clamping arm 32a and the second clamping arm 32b, and one of the adjacent first clamping arm 32a and the second clamping arm 32b can be clamped in one of the clamping holes 36.

[0068] like Figures 1 to 4 as well as Figures 8 to 11As shown, in any of the above two embodiments, when assembling the grounding member 3, the first shielding member 3a is first assembled into the receiving groove 112, so that the extension portion 33 of the first shielding member 3a is inserted into the limiting groove 113, and the supporting arm 34 is in contact with the corresponding grounding terminal G through the giving way groove 114 to form a grounding loop, and then the second shielding member 3b is assembled to the rear side of the insulating body 10, and the second shielding member 3b is abutted against the supporting surface 131 of the protrusion 13. On the one hand, it can prevent the second shielding member 3b from contacting the signal terminal S during assembly, and on the other hand, it can give the second shielding member 3b a supporting force, which facilitates the elastic connection between the second shielding member 3b and the first shielding member 3a and the grounding terminal G. The adjacent first clamping arms 32a and second clamping arms 32b are elastically compressed in the left-right direction Y and clamped into the clamping holes 36, and the adjacent first clamping arms 24a and second clamping arms 24b in the same grounding terminal G are elastically compressed in the up-down direction Z and clamped into the corresponding first clamping holes 37 and second clamping holes 38, so that the first shielding part 3a and the second shielding part 3b are installed. The first shielding part 3a and the second shielding part 3b are clamped together by elastic compression, and the grounding terminal G and the second shielding part 3b are clamped together by elastic compression. In this way, the contact stability between each other is better, and the first shielding part 3a and the second shielding part 3b can be prevented from being offset.

[0069] The utility model has the following beneficial effects:

[0070] 1. By providing the grounding member 3 with a split first shielding member 3a and a split second shielding member 3b, the grounding member 3 only needs to be assembled on one side when being assembled to the insulating body 10. That is, the first shielding member 3a is assembled to the top wall 11 of the insulating body 10, and the second shielding member 3b is assembled to the rear end of the insulating body 10. This simplifies the assembly difficulty of the grounding member 3 and helps improve assembly efficiency. At the same time, the first shielding member 3a and the second shielding member 3b can be formed only by punching without the need for stamping and bending, thereby reducing the difficulty of forming the grounding member 3.

[0071] 2. The first shielding member 3a and the second shielding member 3b are clamped together by elastic compression, that is, the adjacent first clamping arms 32a and the second clamping arms 32b in the first shielding member 3a are elastically compressed along the left-right direction Y and clamped into the corresponding clamping holes 36 of the second shielding member 3b. The grounding terminal G and the second shielding member 3b are clamped together by elastic compression, that is, the adjacent first clamping arms 24a and the second clamping arms 24b in each grounding terminal G are elastically compressed along the up-down direction Z and clamped into the corresponding first clamping holes 37 and the second clamping holes 38. This arrangement ensures better contact stability between each other and can prevent the first shielding member 3a and the second shielding member 3b from shifting.

[0072] 3. The first shielding member 3a is accommodated in the receiving groove 112, the front end of the first shielding member 3a is inserted into the limiting groove 113 and cooperates with the limiting groove 113 in the upper and lower directions, and the first clamping arm 32a and the second clamping arm 32b at the rear end of the first shielding member 3a cooperate with the second shielding member 3b in the upper and lower directions Z, so that the force between the front and rear ends of the first shielding member 3a in the front-to-back direction X is balanced, thereby preventing the first shielding member 3a from arching.

[0073] 4. The number of the first clamping arms 32a and the second clamping arms 32b is set to be the same. This is conducive to the mutual offset of the forces acting on the first clamping arm 32a and the corresponding second clamping arm 32b in the left and right directions Y, thereby ensuring the stability of the clamping of the first shielding member 3a and the second shielding member 3b.

[0074] 5. Relative to setting the first clamping arm 32a and the second clamping arm 32b at the upper end of the second shielding part 3b, so that the first shielding part 3a and the second shielding part 3b need to be assembled along the up-down direction Z, the first clamping arm 32a and the second clamping arm 32b are set at the rear end of the first shielding part 3a, so that the first shielding part 3a and the second shielding part 3b need to be assembled along the front-to-back direction X. In this way, the first clamping arm 32a and the second clamping arm 32b can be prevented from relatively falling out of the clamping hole 36 in the up-down direction Z.

[0075] 6. The guiding portion 311 facilitates guiding the first holding arm 32 a and the second holding arm 32 b smoothly along the edge of the holding hole 36 into the holding hole 36 during assembly.

[0076] 7. The plurality of adjusting portions 35 are accommodated in the groove 115 in a one-to-one correspondence. The adjusting portions 35 are closer to the differential terminal pair relative to the ground terminal G in the up-down direction Z, so as to adjust the impedance of the signal terminal S.

[0077] 8. The plurality of pins 39 at the lower end of the second shielding member 3b correspond one-to-one to the conductive portions 22 of the plurality of grounding terminals G, and both are soldered to the same pad on the circuit board 300. This arrangement can, on the one hand, increase the overall product strength of the electrical connector 100, and on the other hand, enhance the multi-point common ground effect to achieve the purpose of reducing crosstalk.

[0078] 9. By providing a plurality of alternating first latch arms 24a and second latch arms 24b on the connection portion 232 of a ground terminal G, the plurality of first latch arms 24a and the plurality of second latch arms 24b engage one-on-one with the second shielding member 3b, thereby achieving multi-point contact. This increases the return path between the ground terminal G and the grounding member 3, shifting the resonance point to a higher frequency, thereby avoiding resonance points in the desired frequency range. Furthermore, the first latch arms 24a and the second latch arms 24b, when interlocked, can offset the mutual force and prevent the second shielding member 3b from shifting during assembly.

[0079] 10. The supporting surface 131 of the protrusion 13 fits in contact with the second shielding member 3b. On the one hand, it can block the second shielding member 3b in the front-to-back direction X to prevent the second shielding member 3b from contacting the signal terminal S, thereby facilitating the snap-fitting of the first shielding member 3a, the ground terminal G and the second shielding member 3b.

[0080] The above detailed description is only an illustration of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this invention are included in the patent scope of this invention.
