Description

Technical Field

[0001] The present disclosure generally relates to the technical field of connectors, and in particular, to an electrical connector and an electronic system including the electrical connector. Background Art

[0002] This section provides background information related to the present application but this information does not necessarily constitute prior art.

[0003] In the relevant technology, the design of the memory card needs to meet the standard electrical and mechanical performance parameters, so the electrical connector connected to the memory card also needs to be designed based on the standard. With the development of AI, 5.5G and even 6G technology, the storage capacity of memory cards has increased significantly, and the size of memory cards has inevitably increased. However, the space of the printed circuit board of the computer motherboard is limited, and how to achieve higher transmission speed and larger capacity of the electrical connector within the limited space is an urgent problem to be solved.

[0004] In the manufacture of electronic systems, an electrical connector is usually used to connect a computer motherboard to a memory. DDR is a double-rate synchronous dynamic random-access memory (SDRAM). Currently, DDR has become the main choice of memory technology. As DDR technology continues to develop, the response speed and storage capacity of DDR have been greatly challenged. There is an urgent need for an electrical connector adapted to a DDR memory card to allow higher transmission speeds and larger capacity in the same or smaller space. Utility Model Content

[0005] This section provides a general summary of the application, and is not a comprehensive disclosure of its full scope or all of its features.

[0006] The first aspect of the present application provides an electrical connector.

[0007] The electrical connector of the present application can use the same or smaller board area to provide higher-speed transmission for adapter cards with higher capacity (for example, four times the capacity of DDR5), for example, twice the traditional transmission rate. A latch is provided at the first end of the base of the electrical connector of the present application, and the latch can rotate between a locked position and an unlocked position, so as to facilitate the operator to insert and remove the adapter card. In addition, an elastic member is provided on the second guide tower portion at the second end of the base of the electrical connector, so that the adapter card can be inserted and removed by overcoming the elastic force, and the elastic member can firmly clamp and fix the adapter card with a simple design structure.

In addition, an elastic member is provided on the second guide tower portion at the second end of the base of the electrical connector, so that the adapter card can be inserted and removed by overcoming the elastic force, and the elastic member can firmly clamp and fix the adapter card with a simple design structure. Therefore, the electrical connection of the present application can save costs while ensuring the reliability and stability of the adapter card and the electrical connector in terms of electrical and mechanical connection. In particular, in a system where two electrical connectors need to be arranged side by side, the electrical connector of the present application is particularly advantageous, and the two guide tower portions of the electrical connector provided with elastic members are arranged adjacent to each other, so that a side-by-side system configuration can be achieved. Therefore, the asymmetric configuration of both ends of the base of the electrical connector of the present application can save space and realize a side-by-side system configuration.

[0027] The fourth aspect of the present application provides an electrical connector. The electrical connector may include: a base having a receiving groove extending along the length direction of the base and used to receive the bottom of an adapter card, a guide tower connected to an end of the base in the length direction and extending along an insertion direction of the adapter card perpendicular to the length direction; and a latch disposed at an end of the base and capable of rotating around a rotation axis between a locked position and an unlocked position, the rotation axis being formed on the latch and rotatably connected to the base.

[0028] A latch is provided at the base of the electrical connector of the present application, and the latch can rotate between a locked position and an unlocked position, so as to facilitate the operator to insert and remove the adapter card. Therefore, the electrical connection of the present application can ensure the reliability and stability of the electrical and mechanical connection between the adapter card and the electrical connector.

[0029] In some exemplary embodiments, the guide tower may include a guide body and a guide housing accommodating the guide body, the guide body including a support portion extending beyond the guide housing, the support portion being connected to the base.

[0030] In some exemplary embodiments, a lower portion of the guide housing close to the base may be provided with a through opening along the length direction, and the base is provided with a mounting groove for mounting the guide tower and the latch.

[0039] The multiple electrical connectors at the base of the electrical connector of the present application have a smaller spacing. In particular, in the case of DDR memory cards, since DDR has a single-ended signal (SGSG), having a smaller spacing between the electrical connectors will reduce crosstalk, thereby helping to further increase the transmission rate. The electrical connector of the present application can use the same or smaller board area to provide higher-speed transmission for adapter cards with higher capacity (e.g., four times the capacity of DDR5), for example, twice the traditional transmission rate.

[0064] The present application will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present application. It should be noted that the following detailed description of the present application is for illustrative purposes only and is not intended to limit the present application. In addition, the same reference numerals are used in the various drawings to represent the same components.

[0065] In the related art, as the storage capacity of the memory card increases significantly, the size of the memory card also inevitably increases. Considering the limited space of the printed circuit board of the computer motherboard, it is more effective to significantly increase the height of the memory card than to increase the length and width of the memory card. However, the inventors realized that if the columnar members at both ends of the base of the electrical connector are directly molded into higher columnar members, it will inevitably cause the molded columnar members to tilt inward. With the development of AI, 5.5G and even 6G technology, it becomes crucial to reliably connect such a high-memory card with large storage capacity to the electrical connector of the printed circuit board in terms of electrical and mechanical connection.

[0066] The inventors have recognized a technology for manufacturing an electrical connector that can solve some technical problems in the related art, which can provide higher speed transmission for DDR cards with higher capacity (e.g., four times the capacity of DDR5) using the same or even smaller board area, for example, twice the traditional transmission rate.

[0067] The electrical connector of the present application may include a base having a first end and a second end opposite to each other in the length direction of the base. A first guide tower and a second guide tower may be provided on the first end and the second end of the base, respectively. Each of the first guide tower and the second guide tower has a guide body made of a material with high mechanical strength, such as metal, and a guide shell made of an insulating material. By arranging a guide body with high mechanical strength inside the guide shell, a more reliable connection can be made when a high adapter card is inserted into the electrical connector, and even in the presence of a violent shaking environment, the adapter card can be reliably connected to the electrical connector in terms of electrical and mechanical aspects. Compared with the case in which the columnar members at both ends of the base of the electrical connector are directly molded into higher columnar members in the related art, the electrical connector of the present application is provided with a guide body with high mechanical strength inside the guide shell, so that the connected adapter card is in a firm and stable connection state, and even in the case of harsh conditions, there will be no instability such as tilting and shaking.

[0068] With the trend of miniaturization, the available space on the printed circuit board is becoming increasingly limited. The inventors have realized that different structures are provided at both ends of the base of the electrical connector. Specifically, a latch that can rotate between a locked position and an unlocked position can be provided at the first end of the base; and an elastic member can be provided at the second end of the base, so that the adapter card can be inserted and removed by overcoming the elastic force. Particularly advantageously, the two guide towers of the electrical connector provided with elastic members can be arranged adjacent to each other through the above-mentioned technical solution of the present application, so that a side-by-side configuration can be achieved. In the technical solution of the present application, by providing a rotatable latch only at one end of the base, on the one hand, two electrical connectors can be closely installed side by side, so that there is only a small gap between the two electrical connectors, and on the other hand, more DIMMs can be installed on a limited motherboard. This asymmetric structure at both ends of the base of the electrical connector of the present application can save space and achieve a side-by-side system configuration.

[0069] In addition, the base and guide tower of the electrical connector of the present application are independent structures, which helps to manufacture the base through a separate process. On the one hand, it can reduce the size of the base, and on the other hand, it can save the space occupied by the base on the computer motherboard and improve space utilization.

[0070] Considering the convenience of manual operation by an operator in a limited space, a handle for rotating the latch arm around the rotation axis is formed on the latch arm of the present application. The shorter the latch handle is, the more it helps to reduce the occupied space, while the longer the latch handle is, the more it helps to facilitate the operation. In order to strike a balance between space saving and convenience, the handle of the latch of the electrical connector of the present application has a length between 2 mm and 5 mm, so that it can reduce the occupied space and facilitate the convenience of manual operation.

[0071] In the related art, the rotation axis of the latch structure is arranged at the lower part of the latch structure. The inventors realize that the rotation axis arranged at the lower part of the latch arm will occupy more installation space of the base. Compared with the electrical connector of the related art, the rotation axis of the latch of the electrical connector of the present application can be arranged at the bottom position of the base by being arranged to be aligned with the protrusion of the latch arm, which can reduce the length of the installation opening of the latch and reduce the height of the installation opening on the one hand, and reduce the space occupied by the base on the other hand, further improving the space utilization rate of the computer motherboard.

[0072] In the related art, the card connector for clamping the bottom of the adapter card is usually made of plastic. When the adapter card is repeatedly inserted and removed, cracks will appear in the card connector, causing the base of the electrical connector to break and fail to connect reliably. The electrical connector of the present application is provided with a card connector made of a material with high mechanical strength, such as metal, to enhance the stability of the electrical connector, increase the overall strength of the base of the electrical connector, and reduce the risk of the base breaking when the adapter card is repeatedly inserted and removed, thereby achieving reliable electrical and mechanical connection and facilitating the accommodation of taller adapter cards.

[0073] The inventors realize and understand that by using a plurality of electrical connectors stamped from a metal sheet, the width of the plurality of electrical connectors along the length direction X of the base is equal to the thickness of the metal sheet, thereby allowing the manufacture of a plurality of electrical connectors with a smaller spacing. The spacing between the plurality of electrical connectors of the electrical connector of the present application can be in the range of 0.4mm to 0.5mm. Compared with the spacing of 0.85mm in the related art, the electrical connector of the present application can realize a plurality of electrical connectors with a smaller spacing. In particular, since DDR has a single-ended signal (SGSG), a smaller spacing between the electrical connectors will reduce crosstalk, thereby helping to further improve the transmission rate. The electrical connector of the present application is suitable for adapter cards with a smaller spacing (such as narrow DIMM cards). The spacing between the two metal contact parts of the adapter card becomes smaller, which can reduce the length of the dual inline memory module (DIMM) and further reduce the space occupied by the motherboard on the one hand, and can enable the adapter card to accommodate more memory chips and can further increase the DIMM capacity on the other hand.

[0074] The electrical connectors according to some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0075] For the sake of clarity and conciseness in the description, the figure shows the insertion direction Z of inserting the adapter card (such as DDR) into the electrical connector of the present application, the direction X perpendicular to the insertion direction Z (i.e., the length direction X of the base), and the direction Y perpendicular to both the insertion direction Z and the length direction X (i.e., the width direction Y of the base).

[0076] According to a first aspect of the present application, an electrical connector 100 is provided. Figure 1A and Figure 1B As shown, the electrical connector 100 can allow an adapter card 200 to be inserted and electrically connected to the adapter card 200. The adapter card 200 can include but is not limited to a memory card or a graphics card. In some embodiments, the adapter card 200 can be a DDR.

[0077] like Figure 2 and Figure 3As shown, the electrical connector 100 according to some embodiments of the present application may include a base 110. The base 110 may be molded from an insulating material. For example, the insulating material may be plastic. The plastic material used for the base may be selected from at least one of the following: liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon, polyphenylene oxide (PPO) and polypropylene (PP). In some embodiments, the plastic material used for the base may be a thermosetting plastic. In some embodiments, the insulating plastic may include, for example, a glass fiber reinforced insulating material. In some embodiments, the base 110 may be formed as a single piece. The base 110 may be formed in a long strip shape, such as Figure 2 and 3 As shown, the base 110 has a receiving groove 111 extending along the length direction X of the base 110. In some embodiments, the receiving groove of the base can be used to receive the bottom of the adapter card 200, so that when the adapter card is inserted into the receiving groove of the base of the electrical connector, the base can support and fix the bottom of the adapter card.

[0078] The electrical connector 100 according to some embodiments of the present application may include a first guide tower portion 120 and a second guide tower portion 130. Figure 2 and Figure 3 As shown, the first guide tower 120 may be connected to a first end of the base 110 in the length direction X, and the first guide tower 120 may extend along an insertion direction Z of the adapter card 200 that is perpendicular to the length direction X. The second guide tower 130 may be connected to a second end of the base 110 in the length direction X and extend along the insertion direction Z. In some embodiments, the second guide tower 130 may include an elastic member 135. The elastic member 135 may be used to fix the adapter card 200.

[0079] In the related art, when a high memory card with a large storage capacity is inserted into the electrical connector, most of the adapter card exceeds the support arm of the electrical connector, so that any slight shaking of the bottom of the adapter card during use will cause a very significant shaking of the top of the tall adapter card. In the electrical connector of the present application, by providing the first guide tower and the second guide tower at both ends of the base, more parts of the adapter card are supported and fixed by the first guide tower and the second guide tower, so that even in the case of a tall adapter card, reliable electrical and mechanical connection between the adapter card and the electrical connector can be ensured.

[0080] Next, combine Figure 5A and Figure 5B , the detailed structures of the first guide tower portion 120 and the second guide tower portion 130 are described. In some exemplary embodiments, as Figure 5A and Figure 5BAs shown, the first guide tower 120 may include a first guide body 121 and a first guide housing 122 for accommodating the first guide body 121. The first guide body 121 may include a first support portion 123 extending beyond the first guide housing 122. The first support portion 123 may be connected to the first end of the base 110. In some exemplary embodiments, as shown in FIG. Fig. 7A and Figure 7B As shown, the second guide tower 130 may include a second guide body 131 and a second guide housing 132 accommodating the second guide body 131. The second guide body 131 may include a second support portion 133 extending beyond the second guide housing 132, and the second support portion 133 may be connected to the second end of the base 110.

[0081] According to the first guide body 121 of the first guide tower 120 of the electrical connector 100 of the present application and the second guide body 131 of the second guide tower 130 can be made of a material with high mechanical strength. The material for manufacturing the first guide body 121 and the second guide body 131 may include metal, alloy or composite material, and the embodiments of the present application are not limited thereto. In some embodiments, the metal material used for the first guide body 121 and the second guide body 131 may include but is not limited to: iron, aluminum and / or copper. In some embodiments, the alloy material used for the first guide body 121 and the second guide body 131 can select at least one of the following: aluminum alloy, zinc alloy, magnesium alloy, titanium alloy and stainless steel. In some embodiments, the composite material used for the first guide body 121 and the second guide body 131 can select at least one of the following: carbon fiber composite material, glass fiber composite material, polymer-based composite material and metal-based composite material.

[0082] The first guide housing 122 of the first guide tower 120 and the second guide housing 132 of the second guide tower 130 of the electrical connector 100 according to the present application can be made of an insulating material. For example, the first guide housing 122 and the second guide housing 132 can be molded by, for example, plastic. The plastic material used for the first guide housing 122 and the second guide housing 132 can include at least one selected from the following: liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylene oxide (PPO) or polypropylene (PP).

[0083] In the electrical connector of the present application, a guide body with high mechanical strength is provided inside the guide housing, so that a more reliable connection can be made when a tall adapter card is inserted into the electrical connector, and even in an environment with severe shaking due to transportation and the like, the adapter card and the electrical connector can be reliably connected electrically and mechanically. Compared with the case in which the columnar members at both ends of the base of the electrical connector are directly molded into taller columnar members in the related art, the electrical connector of the present application, because a guide body with high mechanical strength is provided inside the guide housing, can make the connected adapter card in a firm and stable connection state, and will not be unstable such as tilting or shaking even under harsh conditions.

[0084] Next, combine Figure 5A and Fig. 7A The other structures of the first guide tower portion 120 and the second guide tower portion 130 are described. In some exemplary embodiments, as Figure 5A As shown, the first guide tower 120 may have a first guide groove 124 for guiding the side of the adapter card 200. Specifically, as shown in FIG. Figure 5A As shown, the first guide shell 122 of the first guide tower portion 120 may have a first side surface 1221 opposite to the second guide tower portion 130 in the length direction X of the base 110 and a second side surface 1222 opposite to the first side surface, and the first guide shell 122 of the first guide tower portion 120 may include a guide groove 124 recessed from the first side surface 1221 of the first guide tower portion 120 toward the second side surface 1222.

[0085] In some exemplary embodiments, Fig. 7A As shown, the second guide tower 130 may have a second guide groove 134 for guiding the side of the adapter card 200. The second guide tower 130 has a first side surface 1331 opposite to the first guide tower 120 in the length direction X of the base 110 and a second side surface 1332 opposite to the first side surface. Fig. 7A The second guide tower 130 may include a guide groove 134 recessed from a first side surface toward a second side surface of the second guide tower 130 .

[0086] By providing a guide groove in the guide tower portion of the electrical connector of the present application, on the one hand, it is convenient to insert and remove the memory card relative to the electrical connector, thereby providing convenience for the user; on the other hand, it is ensured that the electrical connector is firmly held in the guide groove when the memory card is inserted into the electrical connector, further ensuring the stability of the electrical and mechanical connection between the electrical connector and the memory card.

[0087] Recombination Figure 5A and Figure 7B, the detailed structures of the first support portion 123 and the second support portion 133 are described. In some embodiments, the first support portion 123 may include one or more support legs. Figure 5A As shown, the first support portion 123 may be two support legs, and a first guide groove support portion 126 bridging the two support legs may be provided at a portion above the two support legs of the first guide body. In other embodiments, the second support portion 133 may include one or more support legs. Figure 7B As shown, the second support portion 133 may be two support legs, and a second guide groove support portion 136 bridging the two support legs may be provided above the two support legs of the second guide body 131. Other feasible implementations within the scope of the inventive concept of the present application are also permitted, and the present application does not limit this.

[0088] In the electrical connector of the present application, by respectively constructing the first guide body and the second guide body to include a first guide groove support portion and a second guide groove support portion, the adapter card can be provided with stable support when the adapter card is inserted and removed along the guide groove of the first guide tower portion even in harsh environments.

[0089] like Figure 5A and 5B As shown, the first guide body 121 may further include a protrusion 127 disposed at the top of the first guide groove support portion 126, and the protrusion 127 may further include an inwardly recessed slot 128. The top of the first guide groove 124 of the first guide housing 122 includes a snap-fitting portion (not shown) that matches the slot 128 in shape and position, so that when the first guide body 121 is installed in the first guide housing 122, the slot 128 is snap-fitted and fixed by the snap-fitting portion disposed at the top of the first guide groove 124. Figure 5B As shown, the first guide body 121 may further include one or more openings 1262 disposed in the guide groove support portion 126 , so that the weight of the electrical connector can be reduced while saving materials.

[0090] In some embodiments, the first guide body 121 may further include one or more recesses 1231, 1232 disposed on the support legs of the first support portion 123. Figure 5B As shown. A protrusion (not shown) that matches the recess 1231 in shape and position may be provided in the lower portion of the first guide shell 122 near the base 110, so that the protrusion in the first guide shell 122 and the recess 1231 on the first guide body 121 are limited and fixed by snapping, so as to reliably and firmly mechanically connect the first guide body 121 to the first guide shell 122, and prevent shaking due to environmental changes caused by, for example, transportation.

[0091] The first guide body 121 may further include a mounting hole 129 disposed on an end portion of the first support portion 123 in the insertion direction Z. Figure 5A The second guide body 131 may further include a mounting hole 139 disposed on an end portion of the second support portion 133 in the insertion direction Z. Figure 7B When the first guide tower 120 is mounted to the support portion receiving groove 116 (such as Figure 4C As shown in the figure, as will be described below), the mounting hole 129 on the first guide body 121 is exposed from the bottom of the support portion receiving groove 116 in the mounting groove 112 (as shown in the figure). Figure 1A As shown), the mounting hole 129 on the first guide body 121 is used to connect the electrical connector to the motherboard of the computer by, for example, threaded connection and / or bolted connection.

[0092] like Figure 5A As shown, the first guide shell 122 of the first guide tower portion 120 can enclose the first guide groove support portion 126 and the upper portion of the first support portion 123, and the guide groove 124 of the first guide shell 122 includes side walls (not shown) in the width direction Y of the base and staggered protrusions (not shown) arranged on the two side walls. In particular, the protrusions arranged on the two side walls are rounded to apply a clamping force to the adapter card when the adapter card is inserted into the electrical connector, thereby fixing the adapter card more firmly.

[0093] The electrical connector 100 according to some embodiments of the present application may include a latch 140. The latch 140 may be connected to the base 110 and may be rotated between a locked position and an unlocked position. In the locked position, the latch 140 may be able to clamp and fix the adapter card, such as Figure 1A and in the unlocked position, the latch 140 can apply a force to the adapter card in a direction opposite to the insertion direction Z and put the adapter card in a released state, so that the operator can remove the adapter card. In some exemplary embodiments, as Figure 2 and Figure 5A As shown, the lower portion of the first guide housing 122 close to the base 110 may be provided with an opening 125 extending through the first guide housing 122 along the length direction. Figure 4A As shown, the first end of the base 110 may be provided with a mounting groove 112 for mounting the first guide tower 120 and the latch 140. Figure 3 As shown, in some exemplary embodiments, when the first guide tower 120 is installed on the base 110, the opening 125 and the mounting groove 112 can constitute a mounting opening 146 for mounting the latch 140, and the latch 140 is rotatably connected to the base 110 in the mounting opening 146.

[0094] In some embodiments, the latch 140 may be disposed at at least one end of the base of the electrical connector 100. In other embodiments, the electrical connector 100 may include a latch 140 disposed at one end of the base. Other feasible embodiments within the scope of the inventive concept of the present application are also permitted, and the present application is not limited thereto.

[0095] In some embodiments, Figure 3 As shown, the two ends of the electrical connector 100 may include a non-aligned structure, a latch 140 is provided at the first end of the base, and an elastic member 135 is provided in the second guide tower 130 at the second end of the base, and the elastic member 135 can be used to fix the adapter card 200. The latch of the electrical connector of the present application can rotate between a locked position and an unlocked position, so that it is convenient for the operator to insert and remove the adapter card. In addition, the elastic member of the electrical connector of the present application firmly clamps and fixes the adapter card with a simple design structure, so the electrical connection of the present application can ensure the reliability and stability of the adapter card and the electrical connector in terms of electrical and mechanical connection while saving costs. In particular, in a system where two electrical connectors need to be arranged side by side, the electrical connector of the present application is particularly advantageous, and the two guide towers of the electrical connector provided with elastic members are arranged adjacently, so that a side-by-side system configuration can be achieved. Therefore, this asymmetric structure at both ends of the base of the electrical connector of the present application can save space and achieve a side-by-side system configuration.

[0096] In some exemplary embodiments, Figure 6 As shown, the latch 140 may have a long latch arm 142, and a snap-fitting portion 143 for snapping with the adapter card 200 is formed at one end of the latch arm 142 in the length direction. For example, when the latch 140 is in the locked position, the snap-fitting portion 143 of the latch 140 and the snap-fitting opening 201 (such as Fig.10 The other end of the latch arm 142 in the length direction is formed with a rotating shaft 141 rotatably connected to the base 110 and a protrusion 145 for releasing the adapter card 200.

[0097] In some exemplary embodiments, Figure 6As shown, when the latch 140 is in the locked position, the rotation axis 141 of the latch arm 142 is aligned with the protrusion 145 of the latch arm 142 in the length direction X of the base 110. Compared with the electrical connector of the related art, the rotation axis 141 of the latch 140 of the electrical connector of the present application can be arranged at the bottom of the base by being arranged to be aligned with the protrusion 145 of the latch arm 142, which can reduce the length and height of the installation opening of the latch on the one hand, and reduce the space occupied by the base on the other hand, further improving the space utilization of the computer motherboard.

[0098] In some exemplary embodiments, Figure 6 As shown, a handle 144 for rotating the latch arm 142 around the rotation axis 141 is also formed on the latch arm 142. The shorter the handle 144 of the latch 140 is, the more it helps to reduce the occupied space, and the longer the handle 144 of the latch 140 is, the more it helps to facilitate the operation. The handle 144 of the latch 140 of the electrical connector 100 of the present application has a length between 2mm and 5mm, so that it can reduce the occupied space and facilitate the convenience of manual operation. In some embodiments, the length of the handle 144 of the latch 140 of the electrical connector 100 can be 3mm or 4mm. However, considering the limited space of the printed circuit board of the computer motherboard, in some embodiments, the length of the handle 144 of the latch 140 can be shorter. Other feasible embodiments within the scope of the inventive concept of the present application are also allowed, and the present application is not limited to this. In the case of a handle with a shorter latch, it can be considered to use an additional clamping device to press the handle so that the latch rotates between the locked position and the unlocked position.

[0099] According to some embodiments of the present application, the mounting slot 112 of the base 110 of the electrical connector has through openings 1121 and 1122 on both sides of the base 110 in the length direction X, respectively. The through openings 1121 and 1122 of the mounting slot 112 are used to provide sufficient space for the latch 140 to rotate in the locked position and the unlocked position. By providing the through opening 1121 of the mounting slot 112 at the base of the electrical connector, the rotation axis 141 of the latch 140 can be set at the bottom of the base, which can reduce the length and height of the mounting opening of the latch on the one hand, and reduce the space occupied by the base on the other hand, further improving the space utilization of the computer motherboard.

[0100] like Figure 4B As shown, a through support portion receiving groove 115 for receiving the second support portion 133 of the second guide tower portion 130 is provided at the second end of the base portion 110 in the length direction X.

[0101] like Figure 4C As shown, the mounting groove 112 of the base 110 may include: a through support portion receiving groove 116 for receiving the first support portion 123 of the first guide tower portion 120; and a receiving cavity 117 for receiving the rotating shaft 141 and the protrusion 145 of the latch 140. The support portion receiving groove 116 may include a protrusion (not shown) protruding toward the inside of the support portion receiving groove 116 along the length direction X of the base 110 at a predetermined position of the support portion receiving groove 116 in the insertion direction, and the protrusion in the support portion receiving groove 116 in the base 110 and the concave portion 1232 (as shown in FIG. 1 ) on the first support portion 123 are connected. Figure 5B As shown in the figure, the first guide body 121 is fixed by snapping to reliably and firmly mechanically connect the first guide body 121 to the base 110 to prevent shaking due to changes in the environment caused by, for example, transportation.

[0102] In some embodiments, the angle α between the handle 144 of the latch 140 and the upper portion of the latch arm 142 near the engaging portion 143 is less than 90°. Figure 6 As shown. In some embodiments, the angle between the handle 144 of the latch 140 and the upper portion of the latch arm 142 may be between 50° and 60°. In some embodiments, the angle between the handle 144 of the latch 140 and the upper portion of the latch arm 142 may be 55°. The combined design of the angle between the handle 144 of the latch 140 and the upper portion of the latch arm 142 and the handle length allows the operator to apply a larger release force to the adapter card 200 through the protrusion 145 of the latch 140 when applying a smaller pressure to the handle 144, thereby easily removing the adapter card from the electrical connector, making it easier for the operator to operate the electrical connector.

[0103] In some exemplary embodiments, Figure 6 As shown, the latch 140 may include a latch body 140a and a latch housing 140b for accommodating the latch body 140a. The latch body 140a of the electrical connector 100 according to the present application may be made of a material with high mechanical strength. The material used to manufacture the latch body 140a of the electrical connector 100 may include, but is not limited to, metals, alloys, composite materials, etc.

[0104] In some embodiments, the metal material used in the latch body 140a may include, but is not limited to, iron, aluminum, and / or copper. In some embodiments, the alloy material used in the latch body 140a may be selected from at least one of the following: aluminum alloy, zinc alloy, magnesium alloy, titanium alloy, and stainless steel. In some embodiments, the composite material used in the latch body 140a may be selected from at least one of the following: carbon fiber composite material, glass fiber composite material, polymer matrix composite material, and metal matrix composite material.

[0105] In some embodiments, the latch body 140a has a shape that matches the lower portion of the latch arm 142 that faces away from the engaging portion 143, the protrusion 145, and the handle 144. In other words, the latch body is not provided in the upper portion of the latch arm 142, thereby saving materials and costs while ensuring the reliability and stability of the latch.

[0106] The latch housing 140b of the electrical connector 100 according to the present application can be made of an insulating material. For example, the latch housing 140b can be formed by, for example, plastic molding. The plastic material used for the latch housing 140b can include at least one selected from the following: liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylene oxide (PPO) or polypropylene (PP). By arranging a latch body with high mechanical strength inside the latch housing, the operator can effectively transfer the pressure to the adapter card when applying pressure to the handle, and the adapter card can be reliably fixed and smoothly unlocked even after a large number of unlocking and locking.

[0107] Next reference Fig. 7A and Figure 7B The detailed structure of the elastic member is described. In some exemplary embodiments, Fig. 7A and Figure 7B As shown in FIG. 1 , an elastic member 135 may be provided on the second guide body 131 of the second guide tower 130, and the elastic member 135 protrudes toward the first guide tower 120 in a manner that it can be elastically deformed in the length direction X. When the adapter card is installed on the electrical connector, the protruding position of the elastic member 135 protruding toward the first guide tower 120 is aligned with the card opening 202 (see FIG. 20 ) on the adapter card 200. Fig.10 When the adapter card is inserted into the electrical connector, the elastic member 135 is pressed and elastically deformed as the adapter card is inserted. When the card-engaging opening 202 on the adapter card 200 is located at the position where the elastic member 135 is located, the elastic member 135 moves toward the card-engaging opening 202 of the adapter card 200 (such as Fig.10 The second guide body 131 of the second guide tower 130 protrudes and fixes the adapter card 200, thereby achieving a stable mechanical connection. Therefore, the electrical connector of the present application can make the connected adapter card in a firm and stable connection state by arranging the second elastic member 135 on the second guide body 131 of the second guide tower 130, and will not be unstable such as tilting or shaking even under harsh conditions.

[0108] In some exemplary embodiments, Figure 8 and Fig. 9As shown, the base 110 may include a plurality of electrical connectors 113 disposed in the receiving groove 111 and spaced apart along the length direction X. The electrical connector 113 may be made of, for example, metal or any other conductive material. In some embodiments, the material used for the electrical connector 113 may include, but is not limited to: phosphor bronze, beryllium copper, and other copper alloys. The electrical connector 113 may be formed by metal material in any suitable manner, including but not limited to forming the electrical connector 113 by stamping and / or forming. In some embodiments, the electrical connector 113 may be formed as an elongated integral piece. In some embodiments, as Figure 8 As shown, each electrical connector 113 may include a contact end 1131 and a mounting end 1132 located at both ends of the electrical connector 113. The contact end 1131 may be used to electrically connect to the circuit of the adapter card 200. The mounting end 1132 may be connected to the printed circuit board of the computer motherboard, thereby electrically connecting the adapter card 200 to the printed circuit board of the computer motherboard through the electrical connector 100. Figure 4A As shown, the base 110 may include a plurality of slots 118 spaced apart in the length direction of the base 110, and the plurality of slots 118 are disposed on both sides of the receiving groove 111 in the width direction Y of the base 110. The contact end portions 1131 of the electrical connector 113 may extend into the slots 118 of the base 110. The electrical connector 113 may be formed on both sides of the receiving groove 111 of the base 110 into two rows of electrical connectors 113 extending along the length direction X of the base.

[0109] In some embodiments, a plurality of electrical connectors may be stamped from a metal sheet, and the width of the plurality of electrical connectors in the length direction X along the base is equal to the thickness of the metal sheet, and the thickness of the metal sheet may be set to be smaller, thereby allowing the manufacture of a plurality of electrical connectors 113 having a smaller pitch P. In some embodiments, the pitch P between the plurality of electrical connectors 113 may be in the range between 0.3 mm and 0.6 mm. In other embodiments, the pitch P between the plurality of electrical connectors 113 may be in the range between 0.4 mm and 0.5 mm. In particular, the pitch P between the plurality of electrical connectors 113 may be 0.45 mm. Relative to the larger pitch of 0.85 mm between the electrical connectors in the conventional electrical connector, the electrical connector of the present application realizes an electrical connector having a smaller pitch. In particular, in the case of being applicable to DDR, since DDR has a single-ended signal (SGSG), having a smaller pitch between the electrical connectors reduces crosstalk.

[0110] In some embodiments, the electrical connector of the present application may further include a card-engaging opening 203 (see FIG. Fig.10 ) is used for clamping and fixing the clamping member 150, such as Figure 2 and Figure 8 As shown. In this embodiment, the base 110 may have a card connector receiving groove 114 extending along the width direction Y of the base 110. Specifically, the base of the electrical connector may have a card connector receiving groove 114 across both ends of the receiving groove 111 in the width direction Y of the base for receiving the card connector 150. In some embodiments, the electrical connector may have only one card connector 150, and the base 110 may have a card connector receiving groove 114 in the middle position along the length direction X of the base, such as Figure 8 As shown. In some embodiments, although not shown, the electrical connector may also have more than one card connector 150, and the base 110 may have more than one corresponding card connector accommodating groove 114 arranged at equal intervals in the length direction of the base 110. The card connector 150 of the electrical connector of the present application has a groove shape and is made of a material with high mechanical strength. The materials used to manufacture the card connector 150 may include but are not limited to metals, alloys, composite materials, etc. In some embodiments, the card connector 150 is made of a metal material. In conventional electrical connectors, a card connector made of plastic is used, and cracks may appear in the card connector when the adapter card is repeatedly inserted and removed, thereby causing the base of the electrical connector to break and fail to connect reliably. By setting the card connector of the electrical connector to be made of a material with high mechanical strength, the stability of the electrical connector is further enhanced, the overall strength of the base of the electrical connector is enhanced, and the risk of base breakage when the adapter card is repeatedly inserted and removed is reduced, thereby achieving reliable electrical and mechanical connection.

[0111] Reference below Figure 2 The assembly process of the electrical connector is described. The conductor electrical connector 113 is inserted into the base 110 by a manipulator; the first guide body 121 is installed into the first guide housing 122, thereby obtaining the preassembled first guide tower 120; the second guide body 131 is installed into the second guide housing 132, thereby obtaining the preassembled second guide tower 130. The latch 140 is installed into the mounting groove 112 of the base 110 and placed in the unlocked position, and the preassembled first guide tower 120 is installed into the support receiving groove 116 in the mounting groove 112 of the base 110, and the preassembled second guide tower 130 is installed into the support receiving groove 115 in the mounting groove 112 of the base 110. The adapter card 200 is inserted into the receiving groove 111 of the base 110 of the electrical connector 100 along the insertion direction Z, and the latch 140 is placed in the locked position, so that the adapter card is reliably connected and fixed to the electrical connector.

[0112] According to a second aspect of the present application, an electronic system is provided, which includes an adapter card 200 and an electrical connector according to any one of some embodiments of the first aspect of the present application, wherein the adapter card 200 is inserted into the electrical connector 100 along an insertion direction.

[0113] The electrical connector of the present application can use the same or smaller board area to provide higher-speed transmission for adapter cards with higher capacity (for example, four times the capacity of DDR5), for example, twice the traditional transmission rate. A latch is provided at the first end of the base of the electrical connector of the present application, and the latch can rotate between a locked position and an unlocked position, so as to facilitate the operator to insert and remove the adapter card. In addition, an elastic member is provided on the second guide tower portion at the second end of the base of the electrical connector, so as to allow the adapter card to be inserted and removed by overcoming the elastic force, and the elastic member can firmly clamp and fix the adapter card with a simple design structure. Therefore, the electrical connection of the present application can save costs while ensuring the reliability and stability of the electrical and mechanical connection of the adapter card and the electrical connector.

[0114] According to a third aspect of the present application, an electronic system is provided, the electronic system comprising an adapter card 200 and a first electrical connector and a second electrical connector, the first electrical connector and the second electrical connector being the electrical connectors according to any of the embodiments of the first aspect of the present application, such as Fig.11 As shown, the second guide tower portion of the first electrical connector and the second guide tower portion of the second electrical connector are arranged adjacent to each other in the length direction X.

[0115] The electrical connector of the present application can use the same or smaller board area to provide higher speed transmission for adapter cards with higher capacity (e.g., four times the capacity of DDR5), for example, twice the traditional transmission rate. A latch is provided at the first end of the base of the electrical connector of the present application, and the latch can rotate between a locked position and an unlocked position, so as to facilitate the operator to insert and remove the adapter card. In addition, an elastic member is provided on the second guide tower portion at the second end of the base of the electrical connector, so that the adapter card can be inserted and removed by overcoming the elastic force, and the elastic member can firmly clamp and fix the adapter card with a simple design structure. Therefore, the electrical connection of the present application can save costs while ensuring the reliability and stability of the adapter card and the electrical connector in terms of electrical and mechanical connection. In particular, in a system where two electrical connectors need to be arranged side by side, the electrical connector of the present application is particularly advantageous, and the two guide tower portions of the electrical connector provided with elastic members are arranged adjacent to each other, so that a side-by-side configuration can be achieved. Therefore, the asymmetric configuration of both ends of the base of the electrical connector of the present application can save space and realize a side-by-side system configuration.

[0116] According to a fourth aspect of the present application, an electrical connector is provided, which may include a base 110.

Figure 3 As shown. In some embodiments, the receiving groove 111 can be used to receive the bottom of the adapter card 200. The electrical connector can include guide towers 120, 130, which are connected to the ends of the base 110 in the length direction X and extend along the insertion direction Z of the adapter card 200 perpendicular to the length direction X. The electrical connector can include a latch 140, which is disposed at the end of the base 110 and can rotate around a rotation axis 141 between a locked position and an unlocked position, and the rotation axis 141 is formed on the latch 140 and is rotatably connected to the base 110.

[0117] In some embodiments, Figure 1A and Figure 1B As shown, latches 140 and elastic members 135 are respectively provided on both sides of the base of the electrical connector. In other embodiments, latches 140 (not shown) according to some embodiments of the first aspect of the present application may also be provided on both sides of the base 110 of the electrical connector 100. By providing latches 140 on both sides of the base 110 of the electrical connector 100, the operator can more easily remove the adapter card from the electrical connector by applying pressure on the handles of the latches on both sides of the electrical connector.

[0118] In some exemplary embodiments, the guide tower includes a guide body and a guide housing for accommodating the guide body, the guide body includes a support portion extending beyond the guide housing, and the support portion is connected to the base 110. In some exemplary embodiments, a lower portion of the guide housing close to the base 110 may be provided with an opening portion 125 extending through along the length direction, and the base 110 is provided with a mounting groove 112 for mounting the guide tower and the latch 140. In some exemplary embodiments, when the guide tower is mounted on the base 110, the opening portion 125 and the mounting groove 112 may constitute a mounting opening 146 for mounting the latch, and the latch 140 is rotatably connected to the base 110 in the mounting opening 146.

[0119] In some exemplary embodiments, the latch 140 has an elongated latch arm 142, a latching portion 143 for latching with the adapter card 200 is formed at one end in the length direction of the latch arm 142, and a rotating shaft 141 rotatably connected to the base 110 and a protrusion 145 for releasing the adapter card 200 are formed at the other end in the length direction of the latch arm 142. In some exemplary embodiments, a handle 144 for rotating the latch arm 142 around the rotating shaft 141 may also be formed on the latch arm 142.

[0120] In some exemplary embodiments, the base 110 includes a plurality of electrical connectors 113 disposed in the receiving groove 111 and spaced apart along the length direction X, and a pitch P between the plurality of electrical connectors 113 is in a range of 0.3 mm to 0.6 mm.

[0121] The base 110, guide tower portion and latch 140 of the electrical connector according to the fourth aspect of the present application have the same structure as the corresponding components of the electrical connector according to the first aspect of the present application and can achieve the same technical effects, which will not be described in detail here.

[0122] According to a fifth aspect of the present application, a DDR electrical connector is provided. The DDR electrical connector may include a base 110, and the base 110 may have a receiving groove 111 extending along the length direction X of the base 110. The base 110 may include a plurality of electrical connectors 113 arranged in the receiving groove 111 and spaced apart along the length direction X, and the spacing P between the plurality of electrical connectors 113 may be in the range of 0.3 mm to 0.6 mm, such as Fig. 9 In some embodiments, a blanking die contact may be used to effectively reduce the spacing between multiple electrical connectors.

[0123] In other embodiments, the spacing P between the plurality of electrical connectors 113 may be in the range of 0.4 mm to 0.5 mm. In particular, the spacing P between the plurality of electrical connectors 113 may be 0.45 mm. Compared to the larger spacing of 0.85 mm between the electrical connectors in the conventional electrical connector, the electrical connector of the present application realizes the electrical connectors with smaller spacing. The spacing between the plurality of electrical connectors of the electrical connector of the present application allows the use of an adapter card with smaller spacing, such as Fig.10As shown, the spacing D between the two metal contacts of the adapter card can be adapted to the spacing between the multiple electrical connectors of the electrical connector of the present application. The spacing D between the two metal contacts of the adapter card becomes smaller, which can reduce the length of the dual inline memory module (DIMM) and further reduce the space occupied by the motherboard on the one hand, and can enable the adapter card to accommodate more memory chips and further increase the DIMM capacity on the other hand. The electrical connector of the present application is suitable for higher adapter cards. In some embodiments, the height of the adapter card can be in the range of 40mm to 70mm. In particular, the height of the adapter card can be in the range of 50mm to 60mm. In particular, in the case of DDR, since DDR has a single-ended signal (SGSG), having a smaller spacing between the electrical connectors will reduce crosstalk, thereby helping to further improve the transmission rate. The electrical connector of the present application can use the same or smaller board area to provide higher-speed transmission for adapter cards with higher capacity (e.g., four times the capacity of DDR5), for example, twice the traditional transmission rate.

[0124] In some exemplary embodiments, the DDR electrical connector further includes a guide tower portion connected to an end portion of the base 110 in the length direction X and extending along an insertion direction Z of the adapter card 200 perpendicular to the length direction X.

[0125] In some exemplary embodiments, the DDR electrical connector further includes a latch 140 , which is disposed at an end of the base 110 and is rotatable between a locked position and an unlocked position about a rotation axis 141 , which is formed on the latch 140 and rotationally connected to the base 110 .

[0126] The base, guide tower, latch, elastic member, etc. of the DDR electrical connector according to the fifth aspect of the present application have the same structure as the corresponding parts of the electrical connector according to the first aspect of the present application and can achieve the same technical effects, which will not be described in detail here.
