Detailed Description
Referring to fig. 1 to 3, a specific structure of a preferred embodiment of the present invention is shown, which includes a metal frame 10 and a plastic frame 20.
The metal frame 10 is a metal frame 10 formed by integrally forging and pressing, and has first side members 11 provided on both sides. The metal frame 10 further includes a first beam 12 and a second beam 13, the first beam 12 is integrally connected between the rear ends of the two first side beams 11, the second beam 13 is integrally connected between the middle portions of the two first side beams 11, a first accommodating groove 101 is formed between the second beam 13 and the first beam 12, the door panel 22 is connected between the front ends of the two first side beams 11, a second accommodating groove 102 is formed between the door panel 22 and the second beam 13, and different electronic cards can be placed between the first accommodating groove 101 and the second accommodating groove 102.
The plastic frame 20 is fixed on the metal frame 10 by one-time injection molding, the plastic frame 20 is located on the inner side of the metal frame 10, so that a height difference is formed between the inner side of the plastic frame 20 and the inner side of the metal frame 10, a gap is formed between the electronic card and the inner side of the metal frame 10, and a short circuit caused by contact between a functional surface of the electronic card and the metal frame 10 can be effectively prevented. The plastic frame 20 has two second side beams 21 and a door panel 22 integrally connected between the front ends of the two second side beams 21, the door panel 22 can play a limiting effect, and the auxiliary card support is clamped in the electronic device. The two second side beams 21 are respectively positioned at the inner sides of the two first side beams 11 and are fixedly embedded with the two first side beams 11, and the inner sides of the two second side beams 21 and the inner side of the door panel 22 both extend inwards to form a supporting part 211 for supporting an electronic card, and the bottom surface of the supporting part 211 is slightly lower than the lower surface of the metal frame 10, so that the lower surface of the electronic card is lower than the lower surface of the metal frame 10 when the electronic card is placed on the plastic frame 20, a gap is formed between the electronic card and the metal frame 10, and a short circuit caused by the contact of a functional surface of the electronic card and the metal frame 10 can be effectively prevented. Therefore, the electronic card is directly contacted with the plastic frame body without being contacted with the metal frame body 10, so that the risk of short circuit between the electronic card and the metal frame body 10 can be avoided, and meanwhile, the composite type card support has the defects of high metal strength and easiness in metal breakage optimization. The outer edge of the first side beam 11 is concavely provided with a locking groove 104, and the locking groove 104 is used for limiting and clamping with external equipment to be butted, so as to prevent the clamping holder and the external equipment to be butted from sliding mutually. In this embodiment, the inner edge of the first side member 11 is formed with a plurality of grooves 103, and the plurality of grooves 103 are embedded in the second side member 21.
The manufacturing method of the embodiment is detailed as follows:
firstly, the metal frame 10 is integrally formed by forging, then the metal frame 10 is fixed on an injection molding device, the second side beam 21 and the door panel 22 between the two second side beams 21 are integrally injection molded on the inner side surface of the first side beam 11 in the metal frame 10, and finally the composite card holder is taken out of the device.
The utility model discloses a design focus lies in:
the two second side beams on the plastic frame body are molded on the inner side surfaces of the two first side beams of the metal frame body in an injection mode and are fixedly embedded with the two first side beams, and the door plate is formed between the two second side beams, so that the whole composite type card support can have the long service life of the composite type card support on the market, the size of the composite type card support is greatly reduced, and the production cost is reduced; meanwhile, the whole process does not need to be assembled, the production efficiency is high, and the production cost is further reduced.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
