Abstract

The utility model relates to an integrated circuit socket which can effectively improve contact and welding effect in installation process. At least one side edge of a frame body of the containing space of an integrated circuit is provided with a plurality of inserting slots; the contact pin parts of terminals with contact pins and conducting pins are respectively clamped in the inserting slots; the conducting pins are bared at the lower part of the frame body. Protruding members are arranged in a hollow slot at the lower end of the inserting slot to prevent the conducting pins from shrinking inwards. The utility model can be completely and effectively contacted with a printed circuit board in the process of surface installation.

Description

Integrated circuit socket

The utility model relates to a kind of integrated circuit socket, and it is a kind of effect that contacts that can effectively improve integrated circuit socket and printed circuit board (PCB), with the integrated circuit socket of realizing reliably welding.

Integrated circuit is one of indispensable element in the electronic product, it is that media contacts with printed circuit board (PCB) with the integrated circuit socket, in other words, integrated circuit socket and various electronic component are mounted on the printed circuit board (PCB) with surface mounting technology (Surface Mount Techology-SMT), after thermal weld, as required various integrated circuits being inserted in the aforesaid sockets, to satisfy different design requirements, has been the means of widespread in the hyundai electronics industry again.Therefore,, can make integrated circuit can't form path, cause product normally to use, so the contact condition between integrated circuit socket and printed circuit board (PCB) be related to product quality if contact badly between integrated circuit socket and printed circuit board (PCB).

The side of general integrated circuit socket is equipped with a plurality of terminals, contacts with printed circuit board (PCB) and realizes tight welding by this terminal lower end maintenance level.But bad or owing to product quality sometimes owing to reasons such as packing, transportations, make the terminal lower end can't keep level, and cause in the mounted on surface process can't with contacting that printed circuit board (PCB) remains intact.

The purpose of this utility model is to provide a kind of integrated circuit socket, and it can be imitated and improve contacting of integrated circuit socket and printed circuit board (PCB), and realizes welding effectively reliably.

The purpose of this utility model is to realize like this, a kind of integrated circuit socket promptly is provided, comprise a framework, its inside has the surface-mounted integrated circuit accommodation space, at least one side of framework is provided with a plurality of slots, the contact feet that will have the terminal of contact feet and conductive feet respectively partly is clipped in the slot, and this conductive feet is exposed below this framework, and this slot lower end is provided with the protruding member of locating in the horizontal direction for conductive feet by the conductive feet place.

The advantage of the utility model device is that it can prevent to contract in the terminal conductive feet and can guarantee reliably to contact and intact welding with printed circuit board (PCB).

Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, wherein:

Fig. 1 is the stereogram of the utility model socket;

Fig. 2 is the cutaway view of the utility model socket;

Fig. 3 is the terminal scheme of installation of the utility model socket;

Fig. 4 is the stereogram of another embodiment of the utility model socket.

At first see also Fig. 1, integrated circuit socket of the present utility model comprises a framework 10, a plurality of terminal 20, wherein, this framework 10 its inside as shown in Figure 1 has integrated circuit accommodation space 11, its at least one side is provided with a plurality of slots 12, and these slot 12 lower ends are the hollow slots 15 of hollow out state, is respectively equipped with draw-in groove 14 at the vertical dual-side of this slot 12, being provided with protruding member in the hollow slots 15 of lower end horizontal direction, is fin 13 in the present embodiment.This hollow slots 15 position and number be set, can arrange in pairs or groups according to different needs.For example, each hollow slots 15 may cooperate 2 to 3 slots that do not wait 12.In addition, establish fin 13 respectively in the hollow slots 15 horizontal direction both sides of these slot 12 lower ends.

Above-mentioned terminal 20, see also Fig. 1,2, be installed in the above-mentioned slot 12, its upper end is similar spiral helicine, elastic bending and the contact feet 21 that is vertical configuration up and down, the lower end is slightly horizontal conductive feet 22, this contact feet 21, as shown in Figure 3, its both sides are provided with down only hook 23, with above-mentioned draw-in groove 14 screens and unlikely coming off mutually.

During assembling, as shown in Figure 2, terminal 20 is inserted in it from slot 12 lower ends, the contact feet 21 of this terminal 20 is embedded in the slot 12, and make this end hook 23 to be positioned in the above-mentioned draw-in groove 14, and this conductive feet 22 is exposed in the hollow slots 15 of these slot 12 belows.See also Fig. 3, be subjected to the restriction of above-mentioned fin 13 because of this conductive feet 22, even produce when being out of shape making the conductive feet 22 deviation is arranged slightly or may cause this terminal 20 through process such as packing, transportation, these fins 13 also can withstand the horizontal conductive feet 22 of terminal 20, contract in being unlikely to this slot 12 inside.So when carrying out the mounted on surface process, the conductive feet 22 of this terminal 20 can be combined closely with printed circuit board (PCB) reliably.

But the shape of protruding member of the present utility model there is no fixing restriction, as long as it can stop this conductive feet 22 inwardly to contract.So, in the foregoing description the structure of cited outstanding tab style, also can be as shown in Figure 4, horizontal direction in the hollow slots 15 of these slot 12 lower ends is established a cross bar 16, the same purpose that prevents that this conductive feet 22 from inwardly contracting of realizing, the big portion area that these cross bars 16 will occupy hollow slots 15 is set, when if integrated circuit socket is welded on the printed circuit board (PCB) for the first time, there is the conductive feet of part terminal not weld fully, in the time of need carrying out repair welding, this cross bar 16 may more be unfavorable for repair welding than aforesaid fin 13.Therefore, adopt the design of these cross bars 16 can think that another kind is feasible, but non-optimal execution mode.

In sum, the utility model can prevent effectively that by this fin 13 or cross bar 16 ingenious this hollow slots 15 inside that are located at the conductive feet 22 of this terminal 20 from inwardly contracting, and helps repair welding and maintenance simultaneously.
