- DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a memory fastening device that is an improved technology based on currently available memory connectors.
- the ingenious feature of the present invention is that the purpose of tightening the memory can be realized without changing the existing standardized memory connector and the memory structure, and the cost for achieving this is very low, but the effect is very good, A wide market prospect.
- the first thing to note is the implementation principle of the present invention: The existing memory is inserted into the memory slot of the memory connector, and the hook is buckled by the hook fastener.
- the memory bayonet locks the memory.
- the hook fastener of the memory connector just snaps into the memory.
- the hook fastener and the memory slot and the memory circuit board are both plastic and have a certain rigidity, so when the hook fastener of the memory connector can just be snapped into the memory bayonet The lower end of the memory must also be in contact with the bottom of the memory slot.
- the memory cannot be inserted into the memory slot, or the memory can be moved up and down in the memory slot after being inserted.
- the removable memory in the memory slot is easy to loose, so this not only brings great precision difficulties to the memory connector and memory design, but also, even if the size of the memory just meets the design size of the memory slot,
- the rigid connection also makes it easy to loosen the hook fastener when the computer vibrates (because the force between the hook fastener and the memory is not very large, the friction is also small), so that the memory strip is loosened. (Because there is no buckle for the hook fastener).
- the present invention has invented a memory fastening device by virtue of the principle that the elastic means has a damping action (the elastic stress generated by the elastic means can counteract the impact force generated when the vibration is generated).
- the direction of memory looseness or even falling off is toward the outside of the memory slot, and the bottom of the memory slot is Blocking the memory, and the hook-shaped fasteners are often easy to loosen outwards. Therefore, the fastening of the memory not only needs to prevent the looseness of the memory but also the looseness of the memory.
- the main reason for the looseness of the memory is the orientation of the hook-shaped fastener. The main reason is that the memory is loose, and the main reason for the loose memory is that there is a gap between the memory connector and the memory. Therefore, the present invention not only solves the problem that the hook fastener of the memory connector and the friction of the memory are too small, but also needs to solve the problem of the gap existing between the memory connector and the contact portion.
- a memory fastening device 1 includes a memory connector that is inserted into the memory and the fixed memory, the memory connector includes a memory slot 11, a slot arm 12 located at two sides of the memory slot 11, a buckle arm 13 at the two ends of the memory slot 11, and the buckle arm a hinged hook-shaped fastener 14 for fastening a memory, the memory fastening device 1 further comprising an elastic member 17, the elastic member 17 being disposed at the bottom of the memory slot 111 and at the bottom of the memory slot 111 connections.
- the elastic member 17 is an insulating elastic rubber strip, which is laid flat on the bottom 111 of the memory slot.
- the contact surface of the elastic member 17 with the memory 2 is flat, and the connection surface with the bottom portion 111 of the memory slot is also flat.
- the elastic member 17 is bonded to the bottom portion 111 of the memory socket in a bonding manner, and has no bonding material with the memory contact surface. When the memory 2 is pulled out from the memory slot 11, the elastic member 17 is not attached. Pull out.
- the width of the insulating elastic rubber strip is the same as the width of the memory slot, and the length is the same as the length of the memory slot, and the thickness is about 2 mm. The purpose is to ensure that the memory can be inserted after the insulating elastic rubber strip is disposed. Speaking of the memory slot, at the same time after the buckle.
- the hook-shaped fasteners are insulated from the rubber strip
- the elastic force is not too large, and the top of the memory strip is deformed to damage or damage the circuit board of the memory module.
- the designer should consider the twisting force of the memory board, the distance between the memory and the memory slot, and the elastic coefficient of the insulating elastic rubber strip, etc., and design the thickness of the elastic insulating rubber strip. .
- Embodiment 2 In the above Embodiment 1, the insulating elastic rubber strip not only needs to be tight in the state in which the memory is heated.
- Solid memory also needs to play the role of tightening the memory under normal temperature conditions, and the insulating elastic rubber strip has a book
- the volume expansion when the temperature and the memory connection between the memory connection seat is already strong, in the heat state, the volume expansion, will increase the clamping force between the memory and the memory connector, when the volume expands When it is too large, the memory will be topped up, which will deform the memory stick, which will affect the stability of the memory and even damage the memory.
- the volume of the insulating elastic rubber strip increases after being heated and expanded, and the clamping of the memory slot limits the lateral expansion of the elastic insulating rubber strip, so when the insulating elastic rubber strip expands to a certain extent after being heated, it is in a certain It will arch at a position, which will also deform or shift the memory.
- the thermal expansion coefficient of the insulating elastic rubber strip is 0 to 20%.
- the insulating elastic rubber strip in the embodiment 1 is divided into several small pieces as shown in FIGS. 7-8. Insulating elastic rubber block 18, the plurality of insulating elastic rubber blocks 18 are intermittently distributed in the inner bottom portion 111 of the memory slot 11, and there is a gap between the insulating elastic rubber blocks 18, so that the insulating elastic rubber block is thermally expanded. In this case, the deformation of the memory and the memory connector is performed along the bottom parallel to the bottom of the memory slot, and the thickness is not greatly affected.
- the insulating elastic rubber block 18 is a cylinder or a square body, and is preferably a circular mixing body as shown in the embodiment, which is in contact with the memory.
- the bottom surface is a circular plane, and the round noodle of the round mixing body With the memory
- the slot arms on both sides of the slot are in contact.
- Embodiment 3 On the basis of Embodiment 2, the memory pushes up the hook fastener upwards due to the lifting of the elastic member, so that the force of the memory and the hook fastener is increased, and the frictional force is also increased, so When the computer is subjected to vibration, it is not easy to loosen the hook fastener to both sides of the memory slot.
- the memory and the hook fastener are both plastic, and the friction is still too small, in order to increase the friction, Protect memory at the same time
- the "hook” 141 is provided with an elastic spacer 19 at the lower portion, and is connected to the "hook” 141 of the hook-shaped fastener 14 in a bonding manner.
- the contact of the elastic spacer 19 with the bayonet 211 of the memory 2 can significantly increase the friction between the memory and the hook fastener, and at the same time protect the bayonet 211 of the memory 2 from being damaged by the hook fastener. Therefore, the memory fastening device 1 also includes the elastic spacer 19, and the planar shape of the elastic spacer 19 and the "hook" 141 of the hook fastener 14 are the same as the shape of the lower bottom surface in contact with the memory, and the thickness It is 0.5mm ⁇ 1 mm.
- the memory fastening device involved in the above embodiment can be disposed on a common computer motherboard, and the motherboard having the memory fastening device can also be combined with a common memory and disposed on a general computer.
