Electrical connector

Abstract

An electrical connector for receiving an electronic card includes an insulative housing having a longitudinal slot and side walls on either side of the slot in the longitudinal direction, and a plurality of conductive terminals arranged in the side walls and including contact portions extending into the slot, head portions extending upwardly from the contact portions, connecting portions extending downwardly from the contact portions, and solder tails extending downwardly from the connecting portions. The electrical connector includes terminal guards on the side walls that shield the head portions of the conductive terminals. The terminal guards guide insertion of the electronic card at an initial stage of insertion of the electronic card into the slot. As the electronic card continues to be inserted, the contact portions of the terminals are pushed by the electronic card to move within the terminal guards in a transverse direction that is perpendicular to the longitudinal direction.

Description

[Technical Field]

[0001] This invention relates to an electrical connector, and more particularly to an electrical connector for high-frequency transmission. [Background Technology]

[0002] For relevant prior art, please refer to the electrical connector disclosed in Chinese Utility Model Patent CN217062592U, which includes an elongated insulating body and a plurality of conductive terminals fixed to the insulating body. The insulating body includes two opposing side walls and a slot located between the two side walls. The conductive terminals include a contact portion extending into the slot, a fixing portion fixed to the side wall, and a terminal head extending upward from the contact portion toward the side wall. The end of the terminal head abuts against the side wall. In order to improve the high-frequency performance of the conductive terminals, the length of the terminal head is set to be relatively short. When the electronic card is inserted into the slot, there is a high probability of impacting the terminal head, thereby affecting the service life of the conductive terminals.

[0003] Therefore, it is indeed necessary to provide a variety of improved electrical connectors to solve the above problems. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide a high-frequency electrical connector that can effectively protect the terminals.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an electrical connector for receiving an electronic card, comprising an insulating body and a plurality of conductive terminals, wherein the insulating body has a longitudinally elongated slot and sidewalls located on both sides of the slot in the longitudinal direction, the conductive terminals being arranged on the sidewalls and comprising a contact portion extending to the slot, a head extending upward from the contact portion, a connecting portion extending downward from the contact portion, and a solder foot extending downward from the connecting portion; the electrical connector includes a terminal protection member located on the sidewall, the terminal protection member shielding the head of the conductive terminal; in the initial stage of the electronic card being inserted into the slot, the terminal protection member guides the electronic card into insertion; as the electronic card continues to be inserted, the contact portion of the terminal is abutted by the electronic card and moves within the terminal protection member in a transverse direction perpendicular to the longitudinal direction.

[0006] Compared with the prior art, the terminal protector of the present invention floats and shields the head of the conductive terminal. When the electronic card is inserted into the slot, the terminal protector contacts the electronic card first, avoiding the head of the conductive terminal from being directly impacted by the electronic card, which helps to improve the service life of the conductive terminal.

Detailed Implementation Methods

[0040] To facilitate a better understanding of the purpose, structure, features, and effects of this invention, the following is combined with... Figures 1 to 17 This invention describes embodiments of the electrical connector. Figure 1 An electrical connector 100 disclosed in this invention is used to receive an electronic card (not shown). It includes an insulating body 10 and a plurality of conductive terminals 20. The insulating body 10 has a longitudinally elongated slot 11 and sidewalls 12 located on both sides of the slot 11 along its longitudinal direction. Figure 6 , Figure 7 , Figure 12 , Figure 14 , Figure 15 , Figure 17The conductive terminals 20 are arranged in two rows on the side wall 12 and include a contact portion 21 extending to the slot 11, a head 22 extending upward from the contact portion 21, a connecting portion 23 extending downward from the contact portion 21, and a solder foot 24 extending downward from the connecting portion 23. The electrical connector includes a terminal protector 30 located on the side wall 12, which shields the head 22 of the conductive terminals. To improve the protection effect, it is preferred that the terminal protector 30 is correspondingly disposed in the two side walls 12 to protect the two rows of conductive terminals 20. Initially, when the electronic card is inserted into the slot 11, the terminal protector 30 guides the electronic card into the slot; as the electronic card continues to be inserted, the contact portion 21 of the conductive terminal is abutted by the electronic card and moves within the terminal protector 30 in a lateral direction perpendicular to the longitudinal direction. The terminal protector 30 has an abutment portion 31 protruding towards the slot, which shields the head 22 of the conductive terminal 20 and abuts against the electronic card. The sidewall 12 near the slot 11 has a recessed receiving groove 121, and the terminal protection member 30 is disposed within the receiving groove 121; in the lateral direction, a floating gap 122 is provided between the receiving groove 121 and the terminal protection member 30. This invention protects the head 22 of the conductive terminal 20 by providing the terminal protection member 30, effectively preventing the head 22 of the conductive terminal from being exposed and impacted by the electronic card. It also allows for an appropriate shortening of the length of the conductive terminal head 22 during design, which is beneficial for improving the high-frequency performance of the electrical connector 100. Preferably, the length of the conductive terminal head 22 can be set to 0.6 mm, and the abutment portion 31 covers the end of the head 22 by 0.52 mm.

[0041] The first to fifth embodiments of the electrical connector of the present invention have basically the same appearance, the difference being the structure of the terminal protection member. For ease of understanding, only a portion of the longitudinal extension of the electrical connector is shown to further explain the detailed structure of each embodiment. Figures 1 to 15 The illustrations are for the first to third embodiments of the present invention. In these embodiments, the terminal protector 30 is provided with a protective groove 32 corresponding to the conductive terminal 20. The protective groove 32 opens downward, and the head 22 of the conductive terminal 20 is located within the protective groove 32 and can move laterally within the protective groove 32. The electrical connector 100 may include a plurality of terminal protectors 30 to correspond to one or more conductive terminals 20 respectively. To improve assembly convenience, preferably, the terminal protector 30 includes a longitudinally extending main body 33, and the main body 33 is provided with a plurality of longitudinally arranged protective grooves 32.

[0042] Combination Figures 1 to 8In the first embodiment, the terminal protector 30 includes a longitudinally extending main body 33 and a pair of latches 34 extending upward from the main body 33. The main body 33 has a plurality of longitudinally arranged protective grooves 32. The latches 34 include an upwardly extending first extension 341 and a second extension 342 folded downward from the first extension 341. The side wall 12 has a mounting groove 123 communicating with the receiving groove 121. The mounting groove 123 is located above the receiving groove 121. The side wall 12 has a pair of support portions 124 extending to the mounting groove 122. The second extension 342 abuts downward against the corresponding support portion 124. The terminal protector 30 also includes an upwardly extending stop block 35. When the terminal protector 30 floats upward, the stop block 35 abuts upward against the top of the mounting groove 123. This effectively limits the terminal protector 30, giving it a suitable floating range in the vertical direction, preventing it from falling or other abnormalities.

[0043] See Figures 9 to 12 In the second embodiment, the terminal protection member 30 includes a longitudinally extending main body 33 and a fixing part 36 extending downward from the main body 33. The main body 33 is provided with a plurality of longitudinally arranged protective grooves 32. Each row of conductive terminals 20 is injection molded onto an insulating block 40. The fixing part 36 is fixed to the insulating block 40 or the side wall 12. The figure only shows a schematic diagram of the fixing part 36 being fixed to the insulating block 40. Figure 10 and Figure 11 As shown, the fixing part 36 is provided with a plurality of openings 360 to increase the elasticity of the fixing part 36.

[0044] See Figure 13 and Figure 14 In the third embodiment, the electrical connector 100 includes a grounding piece 50 disposed in the receiving groove 121, and the conductive terminal 20 includes a plurality of grounding terminals 201 (see reference). Figure 5 The grounding plate 50 is provided with a grounding spring arm 51, which overlaps with the grounding terminal 201. The terminal protection member 30 is fixed to the grounding plate 50. The grounding plate 50 is a generally longitudinally extending sheet-like body disposed between each row of conductive terminals 20 and the side wall 12. Each row of conductive terminals 20 is injection molded onto an insulating block 40. The grounding plate 50 is fixed to the insulating block 40. The grounding spring arm 51 extends obliquely upward and abuts against the connection portion 23 of the grounding terminal 201 near the contact portion 21. In other embodiments, the grounding spring arm 51 may also be configured in other forms. See reference. Figure 15 As shown, in the fourth embodiment, the grounding spring arm 51 extends downward and abuts against the connection portion 23 of the grounding terminal 201 near the solder foot 24.

[0045] See Figure 16 and Figure 17 In the fifth embodiment, the terminal protection member 30 comprises a plurality of metal springs 60 corresponding to the two rows of conductive terminals 20. These metal springs 60 are arranged longitudinally between each row of conductive terminals 20 and the sidewall 12. Each row of conductive terminals 20 is injection molded onto an insulating block 40. Each metal spring 60 includes a retaining portion 61 and an abutting portion 31 extending upward from the retaining portion 61. The retaining portion 61 is fixed to the insulating block 40 or the sidewall 12. The abutting portion 31 extends upward from the retaining portion 61 and then extends downward at an angle toward the head 22 of the corresponding conductive terminal 20, with its extended end 310 folded inward to avoid scratching the electronic card.

[0046] The above are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention should still fall within the scope of this patent.
