Abstract

A kind of simple clamping formula of the utility model circuit board conversion equipment, it comprises deck and is fixed on the jockey at deck two ends, and deck two ends have the turriform portion formed by a pair top and a pair bottom adjacent to top with this, and this jockey comprises body; The jockey damaged can be changed by the utility model easily, thus avoids way integrated circuit plate conversion equipment must changed because jockey damages existed in the conventional technology, thus reduces the cost, more environmental protection.

Description

Simple clamping formula circuit board conversion equipment

Technical field

The utility model relates to a kind of circuit connection transfer device, particularly relates to a kind of plug-in circuit board conversion equipment.

Background technology

Circuit connection transfer device is a kind of connection device card year circuit board and motherboard circuit are connected to each other be widely used in computer or other circuit arrangement.

Although card can be carried a circuit board and eject by typical electrical connector easily, and can electronic unit around available protecting electric connector, but this typical electrical connector has some shortcomings.First, carry out spacing because fixing end face is in fact main to ejection part, and cannot carry out spacing to insertion section, and the distance between rotating shaft and ejection part is much smaller than the distance between rotating shaft and insertion section, in fact forms the longer arm of force between this insertion section and rotating shaft, when being rotatably inserted into portion, externally applied forces and this longer arm of force acting in conjunction, producing larger turning moment, therefore often because exerting a force too quickly, this jockey being fractureed, thus card cannot be carried circuit board taking-up; Secondly, rotating shaft mounting structure due to typical electrical connector is enclosed construction (i.e. circular hole), and jockey is generally manufactured by hard material, when therefore jockey being installed to electric connector, must by instrument extrusion connecting device by force, once after installing, this jockey is difficult to again separate from electric connector, and then when jockey damages, jockey cannot be changed separately, and overall electric connector must be changed, therefore cost is high, not environmentally.

Thus, a kind of simple clamping formula circuit board conversion equipment solving above-mentioned various problem must be provided.

Summary of the invention

The purpose of this utility model is to provide that a kind of structure is firm, jockey is replaceable, the simple clamping formula circuit board conversion equipment of the low environment-friendly type of cost.

To achieve these goals, a specific embodiment of the present utility model provides a kind of simple clamping formula circuit board conversion equipment, it comprises deck and is fixed on the jockey at deck two ends, deck two ends have the turriform portion formed by a pair top and a pair bottom adjacent to top with this, this jockey comprises body, this is to forming upper arc sections between top, this forms lower arc sections to bottom, this forms the circular hole with opening to lower arc sections and upper arc sections, described lower inner wall is formed plane in the limit be connected with described lower arc sections, the body of this jockey is extruded with the rotating shaft be arranged in above-mentioned circular hole, the abutment face be resisted against in described limit on plane is formed outside rotating shaft.

Below in conjunction with accompanying drawing, describe the utility model in detail by preferred embodiment.

Embodiment

With reference to figure 2-6, the utility model simple clamping formula circuit board conversion equipment 100 comprises one for refuting the deck 12 patching card 80 and the jockey 700 being fixed on deck 12 two ends.

These deck 12 central authorities offer central slot 14 along its length, and these central slot 14 both sides are provided with contact terminal 16, and the two ends of this deck 12 respectively have a turriform portion 20, and this turriform portion 20 comprises a pair top 22 and a pair bottom 24 adjacent to top 22 with this.Form the clip slot 222 be communicated with described central slot 14 between two tops 22, this clip slot 222 top end opening forms the guide portion 224 of inclined plane shape, inserts smoothly in the central slot 14 of deck 12 for guiding described grafting card 80.Be connected with between this two top 22 and strengthen raised line 226, this reinforcement raised line 226 is for strengthening the bonding strength on two tops 22, and the formation of this reinforcement raised line 226 bottom has flexible upper arc sections 2262; This is connected to each other by the linking arm 28 of height lower than bottom 24 between bottom 24, thus make two upper ends, bottom 24 form breach (non-label), this is recessed into the lower arc sections 242 of formation one respectively on the inwall of bottom 24, this forms the circular hole 247 that has opening 249 to lower arc sections 242 jointly with above-mentioned upper arc sections 2262, aftermentioned in detail for holding described jockey 700(), plane 244 in the limit that on the inwall of described bottom 24, recessed formation is simultaneously connected with described lower arc sections 242; The accommodation hole 26 communicated with the breach between described central slot 14, clip slot 222 and two bottoms 24 is offered in this bottom, turriform portion 20, and this accommodation hole 26 top forms near the position of central slot 14 the lowest limit plane 262 of inclination.

Described jockey 700 is installed on deck 12 two ends, it comprises body 72, and this side, body 72 top extends to form insertion section 74, and opposite side extends to form the holding section 76 for fixing grafting card 80, the root 78 of this body 72 has front protuberance 782, and this front protuberance 782 is convexly equipped with ejection part 784.Wherein this body 72 gives prominence to rotating shaft 71 near the position of root 78, forms the abutment face 73 of inclination outside this rotating shaft 71, has the projection 75 fixed to by this jockey 700 on the inwall of bottom 24 near the position of insertion section 74.

With reference to figure 6, when this jockey 700 is installed to deck 12 two ends, first the root 78 of jockey 700 and the corresponding indentation, there of ejection part 784 between two bottoms 24 in turriform portion 20 are put in accommodation hole 26, and rotating shaft 71 is snapped onto in the circular hole 247 that described lower arc sections 242 and upper arc sections 2262 form jointly from opening 249 elasticity, thus the rotation making this rotating shaft 71 can carry out in suitable angular range in this circular hole 247.

When rotating this jockey 700(in insertion section 74 for being extracted on deck 12 by described grafting card 80) to suitable angle time, described front protuberance 782 is propped up by lowest limit plane 262, described abutment face 73 is propped up by plane 244 in limit simultaneously, this double cutting off inflow structure makes this jockey 700 can not to fracture because overexerting in rotary course damage, thus guarantees that the Stability Analysis of Structures of overall electric connector 100 is reliable; In addition, because the circular hole 247 holding rotating shaft 71 has opening 249, rotating shaft 71 relies on the elasticity of opening 249 and is installed in circular hole 247, when jockey 700 damages accidentally, easily the jockey damaged can be changed, thus avoiding the way overall electric connector must changed in the conventional technology, cost lowers and more environmental protection.

Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
