Abstract
The utility model relates to the electric connector technical field, in particular to an inserting card structure having the guiding limit, comprising a connecting base and a daughter board, wherein a plurality of terminals are accepted in the connecting base; tin feet of a plurality of terminals are extended in rows from one end of the connecting base and conform a slot; the daughter board can be inserted into and combined with the slot which is conformed by the corresponding tin feet and realize the electrical connection with the terminal; the corresponding end of the connecting is protruded with tower portions in the same direction as the tin feet; the tower portions are separately arranged on the two ends of the slot; a guiding groove communicated with the slot is disposed on the tower portion; and the corresponding edge of the daughter board is inserted into the corresponding guiding groove when the daughter board is inserted and combined. The utility model adds the tower portions and a boss on the corresponding end of the connecting base and equips the guiding slot on the tower portion, and thus, the daughter board not only has the tin feet to clamp but also has the slot and the boss to cooperate and offer the guiding and limit when the daughter board is inserted and assembled, thereby causing the contacts on the daughter board to have a good contact with the tin feet and advancing the quality of the signal transmission. And moreover, the daughter board is uneasy to loosen, and has stable connection and strong practicability.
Description
Technical field:
The utility model relates to technical field of electric connectors, refers in particular to a kind of tool guide and limit card plugging structure.
Background technology:
Shown in Fig. 1,2, be contained in the terminal in the Connection Block 60, its tin pin 61 directly constructs slot 62 after stretching out Connection Block 60, and outside daughter board 63 inserts in the slot 62 and is implemented in terminal and electrically connects.And existing this structure, it only is that chucking power by tin pin 61 gives positioning and fixing that daughter board 63 inserts slots 62, lacking other supplementary structure locatees, thereby daughter board 63 inserts the stable not good of its connection of back, but also the contact that daughter board 63 often occurs is just engaging not, is walking with tin pin 61, so that influence both electric connections, even can't normally use.
Summary of the invention:
The purpose of this utility model is to overcome the defective of prior art, and a kind of tool guide and limit card plugging structure good, that connection is stable of locating is provided.
For achieving the above object, tool guide and limit card plugging structure described in the utility model comprises Connection Block and daughter board, contains plurality of terminals in the Connection Block; The tin pin of plurality of terminals divides row to stretch out by an end of Connection Block and constructs slot, daughter board can be corresponding the slot of tin pin structure insert combination and realize electrically connecting with terminal, on the respective end of Connection Block, with the tin pin convex with tower portion in the same way, tower section is located at the two ends of slot, and being provided with the gathering sill that is communicated with slot in tower portion, its respective edges was inserted in the corresponding gathering sill when daughter board inserted combination.
In the Connection Block respective end, be positioned at slot and laterally be convexly equipped with and tin pin boss in the same way certain position, and the corresponding boss position leaving certain gaps uncovered by the economic plan of described daughter board is docked with boss.
Described gathering sill directly dissects structure by tower portion, and the bottom surface of gathering sill is a little more than the root of tower portion; The periphery of gathering sill upper port leaves guiding surface.
Be compared with the prior art, the utility model is set up tower portion and boss on the respective end of Connection Block, be provided with the guiding slot in tower portion, like this, daughter board not only has the clamping of tin pin when inserting assembling, and also have slot and boss cooperation to lead with spacing, contact on the daughter board is contacted well with the tin pin, improve the quality of signal transmission, and daughter board is difficult for getting loose, connect stable, practical.

Accompanying drawing 2 is prior art assembling connection diagram;
Accompanying drawing 3 is the utility model connection diagram;
Accompanying drawing 4 is the utility model Connection Block structural representation;
Accompanying drawing 5 is the Connection Block structural representation of band edge;
Accompanying drawing 6 is another visual angle structural representation of Connection Block of band edge.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
See shown in the accompanying drawing 3～6 that tool guide and limit card plugging structure described in the utility model comprises Connection Block 1 and daughter board 2, contains plurality of terminals 3 in the Connection Block 1.The tin pin 31 of plurality of terminals 3 divides row to stretch out by an end of Connection Block 1 and constructs slot 32, and the slot 32 that daughter board 2 can corresponding tin pin 31 structures inserts combination and realizes electrically connecting with terminal 3.On the respective end of Connection Block 1, convex with tower portion 11 in the same way with tin pin 31, tower portion 11 is divided into the two ends of slot 32, and is provided with the gathering sill 12 that is communicated with slot 32 in tower portion 11, and its respective edges was inserted in the gathering sill 12 of correspondence when daughter board 2 inserted combination.Tower portion 11 is directly by the moulding of Connection Block 1 two side ends projection, and the height of tower portion 11 is higher than or the top of concordant tin pin 31, can obtain the gathering sill 12 of enough height like this, and 11 pairs of tin pin 31 partial occlusions of both sides tower portion have the effect of protection.
In the present embodiment, gathering sill 12 directly dissects structure by tower portion 11, and the bottom surface of gathering sill 12 is a little more than the root of tower portion 11; Dissect structure by tower portion 11, processing is simple, and cost of manufacture is low, and is structural good.And the bottom surface of gathering sill 12 promptly leaves clearance space a little more than the root of tower portion 11 between the end face of the bottom surface of gathering sill 12 and Connection Block 1, its inner action need when inserting assembling to satisfy daughter board 2, and assembling is good.Its respective edges was inserted in the corresponding gathering sill 12 when daughter board 2 inserted combination, and gathering sill 12 can limit the four direction all around of daughter board 2, had location and the effect that firmly is connected.The periphery of gathering sill 12 upper port leaves guiding surface 121, and is smooth and easy so that daughter board 2 inserts, and improves assembling speed and efficient.
In the present embodiment, in Connection Block 1 respective end, be positioned at slot 32 horizontal certain position and be convexly equipped with and tin pin 31 boss 13 in the same way, and the 2 corresponding boss 13 position leaving certain gaps uncovered by the economic plans 21 of described daughter board are docked with boss 13.Shown in the figure, the tin pin 31 that boss 13 is arranged at the transversal sectional setting just separates the place, and boss 13 docks with the breach 21 of daughter board 2, can strengthen section connection structure intensity in the daughter board 2, and is structural good.Boss 13 cooperates the gathering sill 12 in the tower portion 11 to give daughter board 2 location and firm together, and the contact of daughter board 2 engages with tin pin 31 accurately, and electric connection is good, improves the plug-in card combination quality.
