Description

Card edge connector This invention relates to a card edge connector. Chinese Utility Model Patent Publication No. CN212257745U discloses a snap-fit ​​connector. An abutment portion extends along the insertion direction of the first insertion end of an additional module on the top wall of the housing. This abutment portion bends towards the first insertion end. When the additional module is inserted into the snap-fit ​​connector, the abutment portion extends along the insertion direction of the first insertion end to guide its insertion. After insertion, the abutment portion elastically abuts against the first insertion end. When the additional module needs to be removed, simply releasing the fixing of the first fixing end causes the abutment portion to press downwards against the first insertion end, thereby causing the first fixing end to spring back. However, the base of this type of additional module is supported and fixed by a metal housing, which can easily lead to deformation and twisting of the metal housing. Therefore, in view of the above problems, it is necessary to provide an improved card edge connector to solve these problems. The purpose of this invention is to provide a card edge connector whose insulating body can fix a heat dissipation module. To solve the aforementioned problems, the present invention can adopt the following technical solution: a card edge connector for fixing a heat dissipation module, the card edge connector including an insulating body and conductive terminals; the insulating body is provided with opposing front end face and rear end face, a top surface located between the front and rear end face, and a card slot penetrating the front end face; the conductive terminal includes a contact portion extending into the card slot, the insulating body includes a support wall extending upward from its top surface, the support wall is provided with a fixing groove penetrating from front to back, the fixing groove being used to accommodate one end of the heat dissipation module. To solve the above-mentioned technical problems, the present invention can also adopt the following technical solution: a snap-fit ​​connector for fixing a heat dissipation module, the heat dissipation module including a fixing plate and a guide plate extending from one end thereto, the guide plate being located above the fixing plate and extending a longer distance; the snap-fit ​​connector includes an insulating body and conductive terminals; the insulating body is provided with opposing front and rear faces, a top surface located between the front and rear faces, and a slot penetrating the front face; the conductive terminals include contact portions extending into the slot; the insulating body includes a support wall extending upward from its top surface, the support wall being provided with a fixing groove penetrating from front to back; the fixing plate of the heat dissipation module is inclinedly inserted into the fixing groove and rotated to a horizontal state and finally fixed in the fixing groove; the guide plate of the heat dissipation module cooperates with the top surface of the support wall to play a guiding role. Compared with the prior art, the present invention provides a support wall on the top of the insulating body, and then uses a fixing groove provided in the support wall to fix the weight of the heat dissipation module, thereby ensuring the stable holding of the heat dissipation module. Figures 1 to 7 illustrate a first embodiment of the present invention, which discloses a retaining connector 100 for fixing a heat dissipation module 200. The retaining connector 100 includes an insulating body 1 and conductive terminals 2. The insulating body 1 has a front end face 11 and a rear end face 12 facing each other, a top surface 13 located between the front and rear end faces, and a retaining groove 14 penetrating the front end face 11. The conductive terminals 2 include a contact portion 21 extending into the retaining groove 14, a lead 22 extending out of the insulating body 1, and a connecting portion 23 connecting the contact portion and the lead. The conductive terminals 2 are arranged in two rows and are respectively fixed to the insulating body 1. The insulating body 1 includes a support wall 161 extending upward from its top surface 13. The support wall 161 has a fixing groove 162 that runs through the front and rear, which is used to receive one end of the heat dissipation module 200. The fixing groove 162 of the support wall 161 supports the weight of the heat dissipation module 200, ensuring stable fixation of the heat dissipation module 200 and preventing the weight of the heat dissipation module from affecting other components. The heat dissipation module 200 includes a fixing plate 201 and a guide plate 202 extending from one end. The guide plate 202 is located above the fixing plate 201 and extends a longer distance. The fixing plate 201 of the heat dissipation module 200 is inserted into the fixing groove 162 at an angle and rotated to a horizontal state and finally fixed in the fixing groove 162. The guide plate 202 of the heat dissipation module 200 cooperates with the top surface 13 of the support wall 161 to play a guiding role. The insulating body 1 includes a first insulating body 15 and a second insulating body 16 mounted on top of the first insulating body 15. A support wall 161 extends upward from the top surface of the second insulating body 16. The second insulating body 16 includes a base 163 and a flat plate portion 164 extending forward from the upper end of the base 163. The support wall 161 extends upward from the front end of the flat plate portion 164. The second insulating body 16 includes a tongue plate 166 extending forward from the base 163 and elastic locking arms 167 located on both sides of the tongue plate 166 and extending forward from the base 163. The tongue plate 166 is located directly below the fixing groove 162. The first insulating body 15 has a limiting groove 151 for receiving the tongue plate 166 and locking grooves 152 located on both sides of the limiting groove 151. The locking arms 167 are mounted from rear to front and locked into the locking grooves 152. The limiting groove 151 extends rearward and upward to form a semi-open structure. The fixing groove 162 has a guide slope 165 that extends backward from the front end of the flat plate 164 beyond the rear end face of the support wall 161. The locking groove 152 is through from front to back and has an upward-through locking notch 153 at its front end. The locking arm 167 protrudes upward from its free end to form a locking protrusion 168. The rear end face of the locking protrusion 168 is engaged with the front end face of the locking notch 153. The edge connector 100 includes a metal housing 3. The metal housing 3 includes a top plate 31 that tightly adheres to the top surface 13 of the insulating body 1, and a reinforcing plate 32 extending upward from the top plate 31 and adhering to the rear end face 12 and top surface 13 of the support wall 161. The reinforcing plate 32 has an opening 321 at a corresponding fixing groove 162. The top and rear end faces of the support wall 161 have an arc-shaped transition. The reinforcing plate 32 continues to extend and adheres to the front end face of the support wall 161, and is located above the fixing groove 162. In the fixed state, the front end of the fixing plate 201 passes through the opening 321 and simultaneously abuts against the inner top surface of the fixing groove 162. The metal housing 3 bends downward at the leading edge of its top plate 31 to form two baffles 33. The two baffles 33 extend downward to cover the front end face of the second insulating body 16 and are located on either side of the support wall 161. The weight of the heat dissipation module 200 is supported by the insulating body 1, preventing the metal housing 3 from deforming due to prolonged support of the heat dissipation module 200. Referring to Figures 8 and 9, the second embodiment of the present invention has an overall structure similar to that of the edge connector in the first embodiment. The only difference is that the metal shell 3 of the edge connector in this embodiment has notches 34 on its top plate surrounding the two sides and the rear end of the support wall 161, but no reinforcing plate is provided to cover the support wall. Referring to Figure 10, the third embodiment of the present invention has a structure similar to that of the edge connector in the first embodiment. The only difference is that the insulating body in this embodiment is a one-piece design, rather than the first and second insulating bodies being assembled vertically as in the first embodiment. In the second and third embodiments, the insulating body has a forward-protruding support portion 17 on its front end face located below the fixing groove. The support portion 17 is used to support the bottom of the heat dissipation module. This support portion structure can also be applied to the first embodiment. The above embodiments are preferred embodiments of the present invention, but not all embodiments. Any equivalent changes to the technical solutions of the present invention made by those skilled in the art based on reading this specification are covered by the scope of the claims of the present invention. 100: Edge connector 1: Insulating body 11: Front end face 12: Rear end face 13: Top surface 14: Slot 15: First insulating body 151: Limiting groove 152: Locking groove 153: Locking notch 16: Second insulating body 161: Support wall 162: Fixing groove 163: Base 164: Flat plate 165: Guide slope 166: Tongue plate 167: Locking arm 168: Locking protrusion 17: Support 200: Heat dissipation module 201: Fixing plate 202: Guide plate 201: Fixing plate 21: Contact part 22: Pin 23: Connecting part 3: Metal shell 31: Top plate 32: Reinforcing plate 321: Opening 33: Baffle 34: Notch Figure 1 is a perspective view of the combination of the card edge connector and the heat dissipation module shown in the first embodiment of the present invention; Figure 2 is a perspective view of the card edge connector and the heat dissipation module shown in Figure 1 in an unassembled state; Figure 3 is a perspective view of the card edge connector shown in Figure 2 from another perspective; Figure 4 is an exploded view of the card edge connector shown in Figure 2; Figure 5 is an exploded view of the card edge connector shown in Figure 4 from another perspective; Figure 6 is a cross-sectional view of the heat dissipation module shown in Figure 1 when it is tilted and inserted into the card edge connector; Figure 7 is a cross-sectional view of the heat dissipation module shown in Figure 6 when it is inserted into the card edge connector and rotated to a horizontal state; Figure 8 is a perspective view of the card edge connector of the second embodiment of the present invention; Figure 9 is a perspective view of the card edge connector shown in Figure 8 from another perspective; and Figure 10 is a perspective view of the card edge connector of the third embodiment of the present invention. 100: Card edge connector 11: Front end 161: Supporting wall 162: Fixing slot 200: Heat dissipation module 2: Conductive terminals 3: Metal casing
