Description

Electrical connector with improved contact arrangement

Technical Field

Embodiments of the present disclosure relate to an electrical connector.

Background

Electrical connectors are used in many electronic systems. Manufacturing a system on several Printed Circuit Boards (PCBs) connected to each other by electrical connectors is generally easier and more cost effective than manufacturing a system as a single component. Conventional arrangements for interconnecting several PCBs typically use one PCB as a backplane. Other PCBs, called daughter boards or daughter cards, are then connected to the backplane by electrical connectors to effect interconnection of the PCBs.

In prior designs, the daughter card was connected to the dielectric housing of the electrical connector after the daughter card was mounted to the electrical connector. The stability of the daughter card to dielectric housing connection can affect the performance of the electrical connection between the daughter card and the electrical connector. How to improve the stability of the daughter card in the housing is a major issue discussed in this application.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present disclosure. One skilled in the art, however, will understand that the following description merely illustrates preferred embodiments of the disclosure and that the disclosure may be practiced without one or more of these details. In addition, some features that are well known in the art have not been described in detail to avoid obscuring the present disclosure.

Card edge connectors are widely used for interconnection between printed circuit boards in electronic systems. DIMMs (dual in-line memory modules) are memory that are currently widely used in computers. DIMMs are interconnected with the motherboard of a computer by card edge connectors. The card edge connector is secured to the motherboard and conductive members on the card edge connector interconnect with circuitry on the motherboard. DIMMs as daughter cards are inserted into receiving slots of card edge connectors, and thus DIMMs are also commonly referred to as memory cards.

The inventors have recognized that vibrations present in the operating environment during use may cause the memory card to wobble relative to the card edge connector, which may reduce the robustness of the memory card to card edge connector connection. The inventors have also recognized that a cause of the memory card rocking relative to the card edge connector may be due to a certain gap between the memory card and an insulating housing of the card edge connector, in particular a certain gap between the memory card and a tower of the insulating housing. The bottom of the memory card is inserted into the receiving slot of the insulating housing and can be clamped by the conductive member on the insulating housing, so that the bottom of the memory card can be firmly fixed on the insulating housing, and the main reason for shaking the memory card relative to the insulating housing may be a gap between the tower and the memory card, thereby causing the memory card to shake in the tower.

The inventors have recognized that reducing the gap between the memory card and the insulative housing helps to avoid situations where the memory card rattles against the card edge connector during use, thereby improving the stability of the interconnect system. In the embodiment of the disclosure, a clamping piece is arranged on the insulating shell. The clamping piece is arranged on the side wall of the receiving groove. When the memory card is kept in the receiving groove of the card edge connector, the clamping piece can clamp the memory card, so that the stability of the insulating shell and the memory card is ensured. The electrical connector of some embodiments is described in detail below with reference to specific embodiments.

As shown in fig. 1-2 and 4-5, the electrical connector 100 may include an insulative housing 300. For clarity and simplicity of description, the vertical direction Z-Z, the longitudinal direction X-X, and the lateral direction Y-Y are defined. The vertical direction Z-Z, the longitudinal direction X-X and the transverse direction Y-Y may be mutually perpendicular. The vertical direction Z-Z generally refers to the height direction of the electrical connector 100. The longitudinal direction X-X generally refers to the length direction of the electrical connector 100. The transverse direction Y-Y generally refers to the width direction of the electrical connector 100.

The insulating housing 300 may have a mating face 301 and a mounting face 302 opposite along the vertical direction Z-Z. The docking surface 301 may have a receiving slot 330 disposed thereon. Illustratively, the receiving slots 330 may be recessed inwardly from the mating face 301 along the vertical direction Z-Z. In particular, the receiving slot 330 may extend along the longitudinal direction X-X. The receiving slot 330 may be used to receive at least a portion of the compliant electrical component to maintain the position of the compliant electrical component relative to the insulating housing 300. Adapting electrical components includes, but is not limited to, electronic cards. The electronic card may include one or more of a graphics card, a memory card, a sound card, and the like. The mating electrical element may also include a mating electrical connector, if possible. The mating electrical connector may be a plug electrical connector, for example, when the electrical connector 100 is a receptacle electrical connector. The principles of the present disclosure will be described below by taking an example of an adaptive electrical component as an electronic card.

For example, the insulating housing 300 may have a substantially elongated bar shape. The insulating housing 300 may extend along the longitudinal direction X-X. The receiving slot 330 may be in the form of an elongated slot extending along the longitudinal direction X-X. The electronic card 900 may be inserted into the receiving slot 330 of the mating face 301, see fig. 1-2 and 4 in combination. Mounting face 302 may be connected to a printed circuit board that serves as a backplane to electrically connect electronic card 900 with the printed circuit board through electrical connector 100 to enable interconnection of circuitry on the electronic card with circuitry on the printed circuit board. Specifically, the insulating housing 300 may be provided thereon with a plurality of conductive members 110. A plurality of conductive members 110 may be disposed in the first and second side portions 311 and 312 spaced apart from each other along the longitudinal direction X-X to ensure electrical insulation between adjacent conductive members 110 from each other. Conductive members (e.g., gold fingers) that may be present on electronic card 900. The front ends of the plurality of conductive members 110 extend into the receiving slot 330. When the edge of the electronic card 900 is inserted into the receiving slot 330, the front ends of the conductive members 110 can be electrically connected to the conductive members on the electronic card 900. The rear ends of the plurality of conductive members 110 may extend beyond the mounting face 302 of the electronic card 900. When the electrical connector 100 is connected to a printed circuit board (not shown), the rear ends of the plurality of conductive members 110 may be electrically connected to circuits on the printed circuit board.

The orientation terms used herein are relative to the electrical connector 100 in the arrangement shown in fig. 1-2, that is, the side where the mating face 301 is located is the upper side, and the side where the opposite mounting face 302 is located is the lower side. Alternatively, the receiving groove 330 may be provided on the insulation case 300 to extend along the longitudinal direction X-X. The insulating housing 300 may be formed of an insulating material such as plastic using a molding process. The insulating housing 300 is typically a unitary piece.

The insulating housing 300 may include a pair of sides 310 and a pair of towers 320. The pair of side portions 310 may extend in the longitudinal direction X-X. The pair of tower portions 320 may be connected to both ends of the pair of side portions 310, respectively. The tower portion 320 may extend in a vertical direction Z-Z. Both ends of the receiving groove 330 may extend into the pair of tower parts 320, respectively. That is, the length of the receiving slot 330 is greater than the length of the side portion 310 along the longitudinal direction X-X such that both ends of the receiving slot 330 extend beyond the side portion 310 into the tower portion 320. The docking surface 301 may be formed on the side portion 310 and the tower portion 320, and the mounting surface 302 may be formed on the side portion 310 and the tower portion 320 as well.

As shown in connection with fig. 4-5 and 11, a reinforcing member 200 may be disposed within one or both of the pair of tower portions 320. Illustratively, a slot 340 may be provided in the tower 320. The reinforcing member 200 may be inserted into the insertion groove 340. The reinforcing member 200 has a U-shaped cross-section. The cross section is a cross section formed by cutting the reinforcing member 200 with a plane perpendicular to the vertical direction Z-Z. The U-shaped opening 201 may face the receiving groove 330. The ends of the receiving slots 330 may extend into the U-shaped opening 201. Both ends of the U-shaped opening 201 are located at both sides of the receiving groove 330, respectively, in the lateral direction Y-Y. That is, the reinforcing member 200 surrounds the end of the receiving groove 330 as viewed in the vertical direction Z-Z. The reinforcing member 200 may be adapted to the shape of the insertion groove 340. As shown in fig. 5, the insertion groove 340 surrounds the end of the receiving groove 330 such that the reinforcing member 200 surrounds the end of the receiving groove 330. Alternatively, the above-described reinforcing member 200 may be provided only in one tower portion 320; alternatively, the reinforcing member 200 may be provided in both the tower portions 320. Desirably, the reinforcing members 200 are provided in both of the tower portions 320, and the two reinforcing members 200 surround both ends of the receiving groove 330, respectively.

The extension of the receiving slots 330 into the tower portion 320 may affect the strength of the tower portion 320. By providing the reinforcing member 200 in the tower portion 320, the tower portion 320 can be reinforced to improve the impact resistance. Particularly in the card edge connector, the entire receiving groove 330 has a longitudinal length significantly greater than a lateral width, which easily causes the tower 320 to be deformed or cracked when an impact force is applied in the lateral direction Y-Y, and therefore, further, the end of the receiving groove 330 protrudes into the U-shaped opening 201 of the reinforcing member 200, so that the reinforcing member 200 can maintain the shape of the tower 320 from both sides of the electronic card 900 in the lateral direction Y-Y when the electronic card 900 is inserted into the receiving groove 330, and prevent the tower 320 from being deformed or cracked when the electronic card 900 is impacted by an external force. In addition, because the vertical height of the tower portion 320 may be greater than the vertical height of the side portions 310, the increased strength of the tower portion 320 may effectively share the impact force on the side portions 310, and may also reinforce the pair of side portions 310, improve the impact resistance thereof, and particularly improve the resistance to the impact force along the transverse direction Y-Y, thereby protecting the insulating housing 300 to a certain extent and avoiding deformation or cracking thereof.

The strength member 200 may be inserted into the slot 340 in any suitable direction, such as a longitudinal direction X-X (not shown) or a vertical direction Z-Z (shown). The slots 340 may have different shapes and configurations when the stiffening member 200 is installed into the tower 320 in different directions. When the reinforcing member 200 is inserted into the insertion groove 340 along the longitudinal direction X-X, the insertion groove 340 may extend to the outer side of the tower 320 along the longitudinal direction X-X. Thus, the reinforcing member 200 may be inserted into the insertion groove 340 from the outer side surface. When the reinforcing member 200 is plugged into the socket 340 along the vertical direction Z-Z, the socket 340 may extend to the mating surface 301 or the mounting surface 302 of the tower 320 along the vertical direction Z-Z. In this way, the reinforcing member 200 may be plugged into the slot 340 from the mating face 301 or the mounting face 302.

The reinforcing member 200 may be made of a strong material such as plastic, ceramic, metal, etc. Preferably, the reinforcing member 200 is made of a metal material. The metal material has higher strength and lower material and processing cost. Preferably, the reinforcing member 200 is an integral sheet metal part. Thus, the strength of the reinforcing member 200 is high, and the processing technology is simple and the cost is low. The insulating housing 300 and the reinforcing member 200 are made of different materials, the reinforcing member 200 is inserted into the insertion groove 340, and the insulating housing 300 and the reinforcing member 200 can be assembled after being manufactured in a split mode, so that the production, the manufacturing and the installation can be facilitated, and the cost of the electric connector 100 can be reduced.

Alternatively, the reinforcing member 200 may be installed in the tower portion 320 in a non-plug-in manner, but the reinforcing member 200 may be enclosed in the insulating housing 300 when the insulating housing 300 is molded. However, this may result in a high mold opening cost of the insulating housing 300.

Further, as shown in fig. 4-5, the slot 340 extends to the abutment surface 301 of the tower 320. The reinforcing member 200 is inserted into the insertion groove 340 from the abutting surface 301. Since the docking surface 301 of the tower 320 is a side of the electronic card 900 that is plugged into the receiving slot 330, the side has a larger view and operation space, and the plugging of the reinforcing member 200 into the slot 340 from the docking surface 301 can facilitate the operation and the experience of use is better. Also, it is possible to check from the abutting surface 301 whether the reinforcing member 200 is properly inserted into the insertion groove 340.

Preferably, as shown in fig. 6-9, the bottom of the insertion groove 340 may have a first step 351 and a second step 352. First step 351 and second step 352 may be spaced apart along lateral direction Y-Y. Both sides of the first step 351 and the second step 352 may form a first recess 361 and a second recess 362, respectively. Third recess 363 is formed between first step 351 and second step 352. The first and second recesses 361 and 362 may be respectively located at both sides of the insertion groove 340 along the transverse direction Y-Y. The lower portion of the reinforcing member 200 is fitted to the bottom of the insertion groove 340. Correspondingly, as shown in fig. 11, the lower portion of the reinforcing member 200 may be provided with a first protrusion 271, a second protrusion 272, and a third protrusion 273. The first protrusion 271, the second protrusion 272, and the third protrusion 273 are inserted into the first recess 361, the second recess 362, and the third recess 363, respectively. The shape and size of first step 351 and second step 352 may be the same or different. The first and second recesses 361 and 362 may be the same or different. By providing the first step 351 and the second step 352, the thickness of the bottom of the tower 320 can be increased, the structural strength of the tower 320 can be improved, the reinforcing member 200 can be better supported, and the reinforcing member 200 can be prevented from impacting the circuit board. In addition, by providing the first recess 361, the second recess 362 and the third recess 363, the dimension of the reinforcing member 200 in the vertical direction Z-Z can be extended as much as possible, and the insulating housing 300 can be protected to a large extent from deformation or cracking.

Further, as shown in fig. 6-9, the third recess 363 may be deeper than the first recess 361 and the second recess 362. Thus, the insertion depth of the main part of the reinforcing member 200 can be increased, which is beneficial to increasing the vertical height of the opening 201, ensuring the interference force of the reinforcing member 200, protecting the tower part 320 to a greater extent and avoiding deformation or cracking.

Optionally, the third recess 363 may also be shallower than or equal to the first and second recesses 361, 362.

Preferably, as shown in fig. 11, the reinforcing member 200 may include a transverse portion 210, a first longitudinal portion 221, and a second longitudinal portion 222. The transverse portion 210 extends in the transverse direction Y-Y. The first and second longitudinal portions 221 and 222 extend from both ends of the transverse portion 210 along the longitudinal direction X-X. The first 221 and second 222 longitudinal portions may be the same or different. The first 221 and second 222 longitudinal portions are spaced apart to form a U-shaped opening 201. The aforementioned first protrusion 271, second protrusion 272, and third protrusion 273 may be provided on the lateral portion 210, first longitudinal portion 221, and second longitudinal portion 222, respectively. The reinforcement member 200 may further include an elastic part 230. The elastic part 230 is bent from the top of the lateral part 210 toward a direction away from the receiving groove 330. The radius of curvature of the elastic portion 230 may be arbitrary. The elastic part 230 may abut against the insertion groove 340. Illustratively, the first longitudinal portion 221, the second longitudinal portion 222, and the elastic portion 230 may be spliced with the transverse portion 210 by welding, bonding, or integrally formed. The elastic portion 230 can function as a guide, when the electronic card 900 is inserted into the receiving slot 330 along the vertical direction Z-Z, the elastic portion 230 can prevent the electronic card 900 from being scratched, so as to effectively insert the electronic card 900 into the receiving slot 330.

Optionally, as shown in fig. 11, the reinforcement member 200 may further include a first extension 251 and a second extension 252. The first and second elongated portions 251 and 252 extend upward from the first and second longitudinal portions 221 and 222, respectively. The first extension 251 and the second extension 252 may be the same or different. Illustratively, the first extending portion 251 and the first longitudinal portion 221, and the second extending portion 252 and the second longitudinal portion 222 may be spliced together by welding, bonding, or the like, or may be integrally formed. The first and second extensions 251 and 252 may increase the vertical dimension of the reinforcing member 200 as much as possible to enhance the resistance of the reinforcing member 200 against the impact force, thereby better protecting the insulating housing 300 from deformation or cracking.

Alternatively, as shown in fig. 11, the transverse portion 210 and the first longitudinal portion 221 may be connected by a first rounded transition 261. The transverse portion 210 and the second longitudinal portion 222 may be connected by a second radiused transition 262. The radii of curvature of the first arc transition 261 and the second arc transition 262 may be arbitrary. Thus, the reinforcing member 200 is easily formed from one plate, and the manufacturing cost is low.

In the illustrated embodiment, as shown in FIG. 4, the receiving slots 330 may extend from the side 310 into the tower 320. The receiving slot 330 may include a card insertion slot 331 and a card locking slot 332. The card insertion slot 331 is located between the pair of side portions 310, and the card insertion slot 331 extends along the longitudinal direction X-X. A partition rib 333 may be provided in the card insertion slot 331 to divide the card insertion slot 331 into a plurality of independent sections. The partition rib 333 not only can increase the mechanical strength of the side portion 310, but also can have a fool-proof function by providing the partition rib 333 at a non-central position of the card insertion slot 331. Conductive members 110 are typically disposed within the side portion 310 for electrically connecting the electronic card 900 with a circuit board. A snap lock slot 332 may be provided in each tower 320. A pair of card locking grooves 332 are respectively located on the sides of the pair of tower portions 320 facing each other, and the pair of card locking grooves 332 extend in the vertical direction Z-Z. The lower ends of the pair of card locking grooves 332 are connected to both ends of the card insertion groove 331, respectively. Thus, the receiving groove 330 of a U shape is formed.

Preferably, as shown in fig. 1-2 and 4, the electrical connector 100 may further include a pair of latches 370. A pair of catches 370 may be connected to a pair of towers 320, respectively. The catch 370 may be removably or pivotably connected to the tower 320. Illustratively, the latch 370 may pivot between a latched position and an unlatched position. The latch 370 is shown in the locked position in fig. 1, and the latch 370 may lock the electronic card 900 to the electrical connector 100. The latch 370 is shown in an unlocked position in FIG. 2, allowing the electronic card 900 to be inserted into the receiving slot 330 or allowing the electronic card 900 to be removed from the insulative housing 300. In this state, the reinforcing member 200 is wrapped within the corresponding catches 370 and tower 320. Therefore, the reinforcing member 200 can be prevented from being polluted by external dust and other dirt, the problems of oxidation and the like of the reinforcing member 200 are avoided, the structural strength of the reinforcing member is ensured, and the insulating shell 300 is better protected. The latch 370 may be formed from a dielectric material, such as plastic, using a molding process. The latch 370 is typically a unitary piece. The material of the latch 370 and the insulating housing 300 may be the same or different.

In order to prevent the electronic card 900 inserted into the receiving groove 330 from shaking with respect to the insulating housing 300 during use, referring to fig. 4-5 in combination, a retaining member 500 may be provided on a sidewall 380 of the receiving groove 330. In general, the side wall 380 may include a first side wall 381 and a second side wall 382 on either side of the receiving slot 330. The first and second sidewalls 381, 382 may be spaced apart along the transverse direction Y-Y, with the receiving slot 330 formed between the first and second sidewalls 381, 382. That is, the first and second side walls 381, 382 may each be provided with the catch 500. The two retainers 500 may face each other or may be staggered by a certain interval in the longitudinal direction X-X. Typically, the two catches 500 are of the same construction, but are arranged as mirror images of each other. Of course, in other embodiments not shown, the catch 500 may be provided on only either one of the first and second side walls 381, 382.

In the illustrated embodiment, because the receiving slot 330 extends into the tower portion 320, the side walls 380 of the receiving slot 330 extend from the sides 310 all the way into the tower portion 320. As shown in fig. 4, the vertical height of the portion of the side wall 380 on the side 310 is less than the vertical height of the portion of the side wall 380 on the tower 320. Illustratively, the catch 500 may be disposed on a portion of the side wall 380 that is on the side 310. Illustratively, the catch 500 may be disposed on a portion of the side wall 380 that is on the tower 320. Illustratively, the catch 500 may be provided on a portion of the side wall 380 on the side 310 and on a portion of the side wall 380 on the tower 320, respectively.

The conductive members 110 are not disposed on the sidewalls of the receiving groove 330 and the inside of the tower 320, and the conductive members 110 are used for clamping and fixing the electronic card 900. And the vertical height of the tower portion 320 is greater than the vertical height of the side portion 310. Due to the limitation of the processing precision, the transverse width of the receiving groove 330 in the tower 320 may be slightly larger than the transverse width of the electronic card 900, so that there may be a gap between the electronic card 900 and the tower 320, resulting in the electronic card 900 shaking relative to the tower 320, and therefore, it is preferable to provide the retainer 500 in the tower 320. And will be described herein with reference to the accompanying drawings.

The retainer 500 may be formed from a material such as metal using a sheet metal process. The catch 500 is typically a unitary piece. As shown in connection with fig. 5 and 12-14, catch 500 may include a jaw 510. Jaws 510 may extend into receiving slots 330. The clamping jaws 510 may be used to apply a resilient force to the electronic card 900 inserted into the receiving slot 330. Specifically, as shown in fig. 3A-3B, the electronic card 900 may gradually approach the jaws 510 as the electronic card 900 moves toward the receiving slot 330. When the electronic card 900 is inserted into the receiving groove 330, the clamping jaws 510 of the two retainers 500 may together exert opposing elastic forces on the electronic card 900 inserted into the receiving groove 330. Thus, the clamping jaws 510 may clamp the electronic card 900, thereby securing the electronic card 900. In the case where the catch 500 is provided in only one side wall, the clamping jaws 510 may apply elastic force to the electronic card 900 in only one direction. Compared with the prior art, the electronic card 900 can also be fixed relative to the position of the insulating shell 300.

In the electrical connector 100 according to the embodiment of the present disclosure, by providing the catch 500 on the side wall 380 of the receiving groove 330, when the adaptive electrical component is inserted into the receiving groove 330, the clamping jaws 510 can clamp the adaptive electrical component in a lateral direction (e.g., a transverse direction Y-Y shown in the figure). In this way, the adaptive electrical component is tightly connected to the insulating housing 300 by the clamping member 500, and even if there is a gap between the adaptive electrical component and the sidewall 380 of the receiving groove 330 due to machining tolerance, the adaptive electrical component does not shake relative to the insulating housing 300, so that the connection stability is high, and the adaptive electrical component held in the receiving groove 330 has good electrical performance. In addition, the clamping member 500 may also function as a supporting beam, so that the mechanical strength of the insulating housing 300 may be enhanced, and the insulating housing 300 may be more durable.

Although in the above embodiment the catch 500 is used in conjunction with the stiffening member 200 within the tower 320, in other embodiments not shown, the catch 500 may be used independently of the stiffening member 200. If desired, a catch 500 may also be provided in the side 310 and a reinforcing member 200 in the tower 320. When the catch 500 is used in combination with the reinforcing member 200 in the tower 320, there is a more excellent effect because; the vertical height of the tower 320 is higher, and the electronic card 900 is more easily shaken relative to the tower 320, so that the structural strength and the clamping capability of the tower 320 are increased, which is more beneficial to ensuring the reliability of the connection between the electronic card 900 and the electrical connector 100, and preventing the electronic card 900 from shaking relative to the electrical connector 100 during the use. Also, in the case where the reinforcing member 200 is provided in the tower 320, providing the separate catches 500 on the sidewalls of both sides of the receiving groove 330, respectively, may make the structure in the tower 320 more compact.

Further, in the case where the electronic card 900 is inserted into the receiving groove 330, the electronic card 900 applies a reaction force to the card 500, forcing the card 500 to apply a pressure to the insulating housing 300 toward the outside of the receiving groove 330. The reinforcing member 200 may be positioned outside the catch 500 with respect to the receiving groove 330. The reinforcing member 200 is located at the outer side of the retainer 500, and may increase the mechanical strength of the portion of the insulating housing 300 located at the outer side of the retainer 500. In this way, the reinforcing member 200 can resist the pressure of the catch 500 against the insulating housing 300.

When the cross section of the reinforcing member 200 perpendicular to the vertical direction is U-shaped, at least a portion of the retainer 500 may be located in the opening of the U-shape. Optionally, catch 500 is located entirely within the opening of stiffening member 200 such that stiffening member 200 encompasses catch 500. The U-shaped reinforcing member 200 is more advantageous in counteracting the pressure of the catch 500 on the insulating housing 300 toward the outside of the receiving groove 330. In the case where the catch 500 is provided, it is more advantageous to secure the mechanical strength of the tower 320. In the case where the catches 500 are provided on each of the two side walls 381 and 382 of the receiving groove 330, the reinforcing member 200 may surround the two catches 500, as shown in fig. 5. Of course, each catch 500 may also have a portion that extends beyond the U-shaped reinforcing member 200.

Illustratively, the jaws 510 may be spring beam-shaped. In the embodiment shown in the figures, the first jaw end 511 of the jaw 510 may be connected to the mount 530. A second jaw end 512 opposite the first jaw end 511 is cantilevered. As such, the second jaw end 512 of the jaw 510 may have some elasticity, thereby forming a spring beam. In other embodiments, the jaws 510 may be made of a resilient material or may have a relatively thin wall thickness, such that the jaws 510 may be in the form of resilient beams. With combined reference to fig. 3A-3B, with this arrangement, the electronic card 900 may be urged against the jaws 510 during movement of the electronic card 900 toward the receiving slot 330 to bend the jaws 510 away from each other, as indicated by the arrows in fig. 3A. When the electronic card 900 is inserted into the receiving slot 330, the clamping jaws 510 may tightly clamp the electronic card 900, as indicated by the arrows in fig. 3B. Therefore, with this arrangement, the clamping jaws 510 have higher strength for clamping the electronic card 900, so that the electronic card 900 is more tightly connected with the insulating housing 300 through the clamping member 500, the electronic card 900 does not shake, and the mechanical performance (e.g., shock resistance) and the electrical performance of the electrical connector 100 are more stable. Also, regardless of the width of the electronic card 900, the electronic card 900 can be tightly held by the elastic characteristics of the clamping jaws 510. Therefore, the requirement for the processing accuracy of the electronic card 900 is reduced, so that the electrical connector 100 is more widely applied.

Illustratively, as shown in fig. 12-14, the jaw 510 may include a curved section 520. The curved section 520 may be located in the middle of the jaw 510. The curved section 520 may be located between the first jaw end 511 and the second jaw end 512. The curved section 520 may be curved toward the inside of the receiving groove 330. In other words, the curved section 520 may protrude toward the inside of the receiving groove 330. The curved section 520 may extend into the receiving slot 330 for applying a resilient force to the electronic card 900 inserted into the receiving slot 330. Thus, the friction between the clamping jaws 510 and the electronic card 900 is small during the process of moving the electronic card 900 to the receiving slot 330, so that the degree of abrasion of the clamping jaws and the electronic card due to friction can be reduced, and the service life of the clamping jaws and the electronic card can be prolonged.

Further, as shown in fig. 12-14, the curved section 520 may include a first curved sub-section 521, an abutting sub-section 522, and a second curved sub-section 523. The first curved sub-section 521 may extend into the receiving slot 330 and connect to one end of the abutment sub-section 522. The second curved sub-segment 523 may extend from the other end of the abutment sub-segment 522 beyond the receiving slot 330. In fig. 14, the abutment sub-section 522 is located to the right of the first curved sub-section 521 and the second curved sub-section 523. Thus, the first curved subsection 521 extends obliquely from the abutment subsection 522 towards the lower left side. The second curved sub-section 523 extends obliquely from the abutment sub-section 522 towards the upper left side. The abutment subsection 522 is protruding with respect to the first and second curved subsections 521, 523. The abutment sub-segments 522 may protrude into the receiving slots 330. The abutment sub-sections 522 may abut the electronic card 900 inserted into the receiving groove 330 to apply an elastic force thereto. The structure of the abutment sub-section 522 may be arbitrary, for example, it may have a straight structure or a curved structure, etc. With this arrangement, the bending section 520 has a simple structure and is inexpensive to manufacture. The abutment sub-section 522 makes surface contact with the electronic card 900 during use, enabling the electronic card 900 to be held more securely.

Illustratively, as shown in fig. 12-14, the edges of the jaws 510 may be rounded 513. By providing the rounded corner 513, the friction between the clamping jaw 510 and the electronic card 900 is small during the process of moving the electronic card 900 to the receiving slot 330, so that the degree of abrasion of the clamping jaw 510 and the electronic card 900 caused by friction can be reduced, and the service life of the clamping jaw and the electronic card can be prolonged.

Illustratively, as shown in fig. 12-14, the catch 500 may further include a mount 530. The mounting block 530 may be plug connected to the side wall 380. The pawl 510 may be coupled to the mount 530. That is, the jaws 510 may be secured to the sidewalls 380 of the receiving slots 330 by the mounting seats 530. In other embodiments not shown, the pawl 510 may also be secured to the side wall 380 of the receiving slot 330 by welding, adhesive, fastener attachment, integral molding, or the like. Thus, the clamping piece 500 can be manufactured separately from the insulating housing 300 and then assembled together in an inserting manner, so that the processing difficulty is reduced.

In one embodiment, the clamping jaw 510 may be spaced apart from the mount 530 along the transverse direction Y-Y. The mount 530 may be remote from the receiving slot 330 relative to the jaws 510. One end of the clamping jaw 510 may be connected to the mounting block 530 by a connecting portion 540. Illustratively, the jaw 510 may have oppositely disposed first and second jaw ends 511, 512. The first jaw end 511 may be further from the abutment surface 301 (see fig. 4) relative to the second jaw end 512, and correspondingly the second jaw end 512 may be relatively closer to the abutment surface 301. Mount 530 may have oppositely disposed first and second mount ends 531 and 532. First mount end 531 may be farther from docking surface 301 relative to second mount end 532, and correspondingly, second mount end 532 may be relatively closer to docking surface 301. The first jaw end 511 and the first mount end 531 may be connected by a connection 540. So configured, the catch 500 can be securely fixed to the side wall 380. Also, the jaws 510 may be spring beam-shaped.

In some embodiments of the catch 500 ', as shown in fig. 15a-15b, the connection 540' may also be connected between the second jaw end 512 'and the second mount end 532'. Illustratively, in both sets of embodiments shown in fig. 12-14 and 15a-15b, the connecting portions 540 and 540' may be U-shaped. The main differences are: in the embodiment shown in fig. 12-14, the U-shaped connecting portion 540 opens toward the mating face 301 (see fig. 4) of the insulating housing 300, and illustratively, the first jaw end 511 and the first mount end 531 may be connected to both ends of the U-shaped connecting portion 540, respectively; whereas in the embodiment shown in fig. 15a-15b, the U-shaped connection portion 540 'opens toward the mounting face 302 of the insulated housing 300 (see fig. 4), illustratively, the second jaw end 512' and the second mount end 532 'may be connected to both ends of the U-shaped connection portion 540', respectively. The mounting seat 530 and the clamping jaw 510 are connected by the U-shaped connecting portion, so that the clamping jaw 510 can be provided with better elasticity, and the clamping member 500 and the electronic card 900 can be connected more tightly.

It should be noted that the same reference numerals will be used for the same or similar parts of the embodiment shown in fig. 15a-15b as the embodiment shown in fig. 12-14, and they will not be described in detail herein for the sake of brevity.

For example, as shown in fig. 12-14, the longitudinal dimension of the connecting portion 540 (i.e., the dimension along the longitudinal direction X-X) may be smaller than the longitudinal dimension of the mount 530. In this way, a step may be formed between the connecting portion 540 and the first mount end 531 to facilitate the mount 530 abutting against a boss 394 (described in detail below) to facilitate securing the catch 500.

Illustratively, as shown in fig. 12-14, second mount end 532 of mount 530 may be provided with a slot 533. The second jaw end 512 of the jaw 510 may extend toward the slot 533. The second jaw end 512 may extend into the slot 533 when the electronic card 900 is received in the receiving slot 330. Through setting up fluting 533, the space of clamping jaw 510 elastic deformation is bigger to can make the elasticity effect of clamping jaw 510 better, and then can make a card hold piece 500 and insulating housing 300 and be connected more closely.

For example, as shown in fig. 15a-15b, to increase the movement space of the clamping jaw 510, a slot similar to the slot 533 may be provided at the first mounting seat end 531' of the mounting seat 530. However, to simplify construction, ease of machining and manufacture, first mount end 531 'of mount 530 distal from interface 301 (see fig. 4) may be shorter than first jaw end 511' of jaw 510 distal from interface 301. In a direction toward the mounting face 302 (see fig. 4), the first jaw end 511 'may extend beyond the first mount end 531', i.e., the first jaw end 511 'is closer to the mounting face 302 than the first mount end 531' and is further from the docking face 301. Thus, when the electronic card 900 is inserted into the receiving groove 330, the first jaw end 511 'may protrude below the first mounting seat end 531', so that the jaw 510 may be elastically deformed with a larger space, and thus the jaw 510 may have better elasticity.

Illustratively, as shown in fig. 6-10, the side wall 380 may be provided with mounting slots 391 and jaw slots 392. The mounting groove 391 and the jaw groove 392 may each extend from the mating face 301 toward the inside of the insulating housing 300. The jaw groove 392 may communicate between the mounting groove 391 and the receiving groove 330 in the lateral direction Y-Y. That is, the receiving groove 330, the mounting groove 391, and the jaw groove 392 communicate with each other. The mount 530 may be fixed in the mounting groove 391. The jaws 510 are movably disposed within the jaw slots 392. Specifically, the longitudinal dimension of the jaw 510 may be smaller than the longitudinal dimension of the jaw slot 392, such that movability may be achieved. Through the arrangement, the structure of the insulating shell 300 for fixing the clamping piece 500 is simple, and the manufacturing cost is low.

Illustratively, as shown in fig. 6-10, a receiving groove 393 may also be provided on each of the side walls 380. The receiving grooves 393 may be recessed from the mounting grooves 391 and the jaw grooves 392 toward a direction away from the docking surface 301 (i.e., a direction facing the mounting surface 302). That is, the receiving groove 393 may be located at the bottom of the mounting groove 391 and the jaw groove 392, and communicate with the mounting groove 391 and the jaw groove 392 each other. The connecting part 540 may be received in the receiving groove 393. The receiving groove 393 may be narrower than the mounting groove 391 in the longitudinal direction X-X, so that the boss 394 may be formed. The mount 530 may abut the boss 394. The boss 394 can act as a limit, and when the mounting seat 530 abuts against the boss 394, the clamping member 500 can be ensured to be mounted in place, so as to ensure that the mechanical performance and the electrical performance of the electrical connector 100 are more stable.

As an example. As shown in fig. 6-10, the lower portion of the jaw slot 392 may have a longitudinal dimension that is less than the longitudinal dimension of the mounting slot 391. The lower portion of the jaw groove 392 may communicate in the middle of the mounting groove 391 in the longitudinal direction X-X. Thus, the mounting slot 391 and the jaw slot 392 may be generally T-shaped when viewed in the vertical direction Z-Z. With this arrangement, the movement of the mount 530 in the transverse direction Y-Y can be restricted, so that the chucking member 500 can be more closely coupled with the insulating housing 300.

As an example. As shown in fig. 6-10, the upper portion of the jaw slot 392 can have a greater longitudinal dimension than the lower portion thereof. Thus, the upper portion of the jaw slot 392 can act as a guide when the jaw 510 is inserted into the jaw slot 392. Even if the clamping jaw 510 deviates during the moving process, the clamping jaw 510 can be guided due to the large longitudinal dimension of the upper part of the clamping jaw slot 392, so that the deviation of the clamping jaw 510 can be corrected, and the clamping jaw 510 can not be normally inserted into the clamping jaw slot 392.

As an example. As shown in fig. 6-10, the upper portion of the jaw slot 392 may have a longitudinal dimension comparable to the longitudinal dimension of the mounting slot 391. An upper portion of the jaw slot 392 may be aligned with the mounting slot 391 along the longitudinal direction X-X. That is, both side walls of the upper portion of the jaw slot 392 may be located on the same plane as both side walls of the mounting slot 391, respectively, along the longitudinal direction X-X. Thus, the structure of the insulating housing 300 is simple and the manufacturing cost is low.

Although not shown, as would be apparent to one skilled in the art based on the foregoing description, the catch 500 'shown in fig. 15a-15b may also mount the catch 500' via mounting slots and jaw slots similar to the mounting slots 391 and jaw slots 392. Thus, the above description of the mounting slots 391 and the jaw slots 392 can be used with the embodiment shown in FIGS. 15a-15 b. It should be noted that, since the connecting portion 540' is disposed close to the abutting surface 301 (see fig. 4) in the embodiment shown in fig. 15a-15b, the accommodating groove 393 described above is not required to be disposed.

Furthermore, in order to firmly connect the mounting seat 530 to the mounting groove 391, the mounting seat 530 shown in fig. 15a-15b and the mounting seat 530 shown in fig. 12-14 may be provided with a first abutting projection 550 and/or a second abutting projection 560. The first and second abutment projections 550 and 560 will be described below by way of example in fig. 12 to 14. The first abutting projection 550 may be provided on one or both of two side surfaces of the mount 530 opposite in the longitudinal direction X-X. The first abutting protrusion 550 may abut against a sidewall of the mounting groove 391. By providing the first abutting projection 550, the material consumption of the retainer 500 can be reduced, thereby reducing the cost of the electrical connector 100. Furthermore, the abutting area of the mounting seat 530 and the mounting groove 391 can be reduced, so that the friction can be reduced in the mounting process, and the mounting is convenient; but also can reduce the possibility of the abutting surface not adapting caused by the uneven abutting surface and reduce the requirement on the machining precision.

Illustratively, as shown in fig. 12-14, the first abutment projection 550 may include a face 551, a face 552, and a face 553. Surface 551, surface 552, and surface 553 surround and form first abutment projection 550. Face 551 faces docking face 301 (see fig. 4), face 553 faces away from docking face 301, and face 552 connects between face 551 and face 552. Wherein the face 553 may be inclined toward the outside of the mount 530 in a direction facing the docking face 301. Like this, when mount 530 pegs graft to mounting groove 391, it can play the guide effect to first support to lean on protruding 550, can rectify the mount 530 of deviation, avoids mount 530 can't normally peg graft in mounting groove 391.

For example, as shown in fig. 12-14, the side of the mounting seat 530 on which the first abutting protrusion 550 is disposed may be further provided with a second abutting protrusion 560. The second abutment projection 560 may abut against a side wall of the mounting groove 391. Along the vertical direction Z-Z, the second abutment projection 560 and the first abutment projection 550 may be spaced apart. The second abutment projection 560 is closer to the abutment surface 301 than the first abutment projection 550 (see fig. 4). The second abutment projection 560 is more convex than the first abutment projection 550. That is, the longitudinal dimension of the second abutment projection 560 is larger than the longitudinal dimension of the first abutment projection 550. By providing the second abutting projection 560, the coupling strength of the mount 530 and the mounting groove 391 can be further improved. In addition, with reference to fig. 4-5, when the mounting seat 530 is inserted into the mounting groove 391, compared with the second abutting protrusion 560, the stroke of the first abutting protrusion 550 in the mounting seat 530 is longer, and by reducing the protruding amount of the first abutting protrusion 550 by a proper amount, the friction between the mounting seat 530 and the mounting groove 391 can be reduced, which is convenient for installation. Meanwhile, since the insulation housing 300 is usually made of plastic, and the retaining member 500 is usually made of metal, when the mounting seat 530 is inserted into the mounting groove 391, the first abutting protrusion 550 can abut against the side wall of the mounting groove 391, so that the side wall of the mounting groove 391 is recessed outwards, the longitudinal dimension of the mounting groove 391 can be expanded in a proper amount, a space is provided for the second abutting protrusion 560 to move in the mounting groove 391, and the friction between the mounting seat 530 and the mounting groove 391 can be further reduced, thereby facilitating the installation.

Illustratively, as shown in fig. 12-14, the second abutment projection 560 may include a face 561, a face 562, and a face 563. The face 561, the face 562, and the face 563 enclose to form the second abutting projection 560. Face 561 faces abutment face 301 (see fig. 4), face 563 faces away from abutment face 301, and face 562 is connected between face 561 and face 562. Wherein the face 563 may be inclined toward an outer side of the mount 530 in a direction facing the docking face 301. Thus, when the mounting seat 530 is inserted into the mounting groove 391, the second abutting protrusion 560 can play a guiding role, so that the deviation of the mounting seat 530 can be corrected, and the mounting seat 530 cannot be normally inserted into the mounting groove 391 is avoided.

In another set of embodiments, such as the catch 500 "shown in fig. 16a-16b and the catch 500'" shown in fig. 17a-17b, the jaw 510 "and the mount 530" are arranged in series along the vertical direction Z-Z, with one end of the jaw 510 "connected to the mount 530". In the foregoing embodiment, the jaws and the mounts are spaced apart in the lateral direction, forming a "left-right configuration". In the retainer 500 "and the retainer 500", the holding jaw 510 "and the mounting seat 530" are connected in series in the vertical direction Z-Z to form a "lower-upper structure" as shown in the drawings. One end of the clamping jaw 510 "may be directly connected to the mounting block 530". The main difference between the two is that: a second jaw end 512 "(i.e., the end near the interface 301 shown in fig. 4) of the jaw 510" of the catch 500 "is connected to a mount 530"; and a first jaw end 511 "of jaw 510" of catch 500' "(i.e., the end remote from interface surface 301 shown in fig. 4) is connected to mount 530". This configuration takes up less space in the transverse direction Y-Y and therefore the jaw 510 "can be more curved, giving it better resilience. The middle portion of the clamping jaw 510 "may be bent towards the receiving groove, i.e. towards the electronic card 900, forming a bent section 510" to apply a resilient force to the electronic card 900.

The jaw 510 "has another end, in addition to the end connected to the mount 530", the jaw 510 "which, in the catch 500" shown in fig. 16a-16b, is a first jaw end 511 ". The first jaw end 511 "may be shorter than the second jaw end 512" along the transverse direction Y-Y such that the first jaw end 511 "is spaced apart from the mount 530" along the transverse direction Y-Y, such as by a distance D. Thereby, the first jaw end 511 ″ as the free end can be made to have a larger movement space.

Similarly, in the catch 500' "shown in fig. 17a-17b, the second jaw end 512" may be shorter than the first jaw end 511 "along the transverse direction Y-Y such that the second jaw end 512" is spaced from the mount 530 "along the transverse direction Y-Y. Thereby, the second jaw end 512 ″ as a free end can be made to have a larger movement space.

Illustratively, in catch 500 "and/or catch 500'", the longitudinal dimension of jaw 510 "may be less than the longitudinal dimension of mount 530". The mounting block 530 "has a large longitudinal dimension that may facilitate mounting of the mounting block 530" in the side walls of the receiving slot. While the jaws 510 "have a smaller longitudinal dimension, the size of the jaw slots in the side walls for receiving the jaws 510" may be reduced, thereby increasing the mechanical strength of the insulating housing 300.

To install the catch 500 "or the catch 500'", the side walls of the receiving groove 330 may be provided with mounting grooves and jaw grooves. The mounting slot and the jaw slot may both extend from the interface surface toward the interior of the insulated housing. The jaw slot may be located between the mounting slot and the receiving slot in a lateral direction. The mounting seat can be fixed in the mounting groove, and the clamping jaw movably sets up in the clamping jaw inslot. For catch 500 ", the mounting slot may extend only a short distance from the interface, while the jaw slot may extend a longer distance. In order to provide sufficient space for the first jaw end 511 ", the jaw slot may extend all the way to near the first jaw end 511", so that the first jaw end 511 "may move into the jaw slot when the jaw 510" applies a resilient force to the electronic card 900. For catch 500 "', the mounting slot may extend only a longer distance from the interface, while the jaw slot may extend a shorter distance. The second jaw end 512 "may move into the mounting slot when the jaw 510" applies a spring force to the electronic card 900.

For example, in order to enable the mounting seat 530 "to be securely connected with the mounting groove, the mounting seat 530" of the catch 500 "may be provided with the first abutting projection 550 and/or the second abutting projection 560 described above. Optionally, the mounting seat 530 "of the catch 500'" may also be provided with the first abutment projection 550 and/or the second abutment projection 560 described above. The first and second abutment projections 550 and 560 may refer to the description of the corresponding parts above, and will not be further detailed herein for the sake of brevity.

Thus, the present disclosure has been described with respect to several embodiments, but it will be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art in light of the teachings of the present disclosure, and fall within the spirit and scope of the present disclosure. The scope of the disclosure is defined by the appended claims and equivalents thereof. The foregoing embodiments are presented for purposes of illustration and description only and are not intended to limit the present disclosure to the scope of the described embodiments.

Various changes may be made to the structures illustrated and described herein. For example, the above-described card is used on a card edge connector, but the card may also be used for any suitable electrical connector, such as a backplane connector, a daughter card connector, a stacking connector (stacking connector), a mezzanine connector (mezzanine connector), an I/O connector, a chip socket (chip socket), a Gen Z connector, and the like. When these connectors are used, the stability is insufficient, and the clamping piece can well enhance the stability of the adaptive electrical component connected with the connectors.

Moreover, while many of the inventive aspects are described above with reference to a vertical connector, it should be understood that aspects of the disclosure are not so limited. As such, any of the inventive features, alone or in combination with one or more other inventive features, can also be used with other types of electrical connectors, such as right angle connectors, coplanar connectors, and the like.

In the description of the present disclosure, it is to be understood that the directions or positional relationships indicated by the directional terms such as "front", "rear", "upper", "lower", "left", "right", "lateral", "vertical", "horizontal", and "top", "bottom", etc., are generally based on the directions or positional relationships shown in the drawings, and are for convenience of description and simplicity of description only, and in the case of not making a reverse description, these directional terms do not indicate and imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the present disclosure; the terms "inner" and "outer" refer to the interior and exterior relative to the contours of the components themselves.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe the spatial relationship of one or more components or features shown in the figures to other components or features.
