Description

The improved terminal structure of board to board connector

Technical field

The utility model provides a kind of improved terminal structure of board to board connector, particularly provide one can cooperate the relative position of adjusting between circuit board, and more help setting of electric circuit, and the connector construction that electric circuit connects between forming circuit plate and circuit board really.

Background technology

Press, in the piece electrical circuit of general electric equipment, mainly be the main body that sets as electric component by circuit board, and constitute the circuit link between the electric component, to reach the effect of integrating operation via the laying of electric circuit; Again, the body that the cloth of its electric circuit is made as the energy electric equipment matches, and can be towards the direction design that is connect with most sheet circuit boards, in the hope of more meeting the demand of spatial configuration.

Therefore, it is the sleeve that utilizes connector that electric circuit is promptly arranged, and further the electric circuit between the forming circuit plate connects, its connector makes the effect that the electric circuit between circuit board connects mutually except having, more has the plug characteristic that to substitute between the circuit board that order connects mutually, and make setting of piece electrical circuit more meet the design of modularization demand, and to make things convenient for the maintenance of electric circuit, convenient even upgrading to the electric circuit function.

Moreover, connector (being also referred to as board to board connector) in order to the connection of forming circuit plate, be by be fixedly arranged on respectively on the circuit board the connection bull with connect parent part sleeve be combined into mutually, and the linking of its circuit promptly connects bull and connection parent part the sleeve male seat of fit and the terminal on the sleeve female seat is overlapped and form mutually by being located at, therefore regular meeting promptly causes because of external force effect improperly and connects bull and be connected getting loose of parent part, and comes in contact bad phenomenon; So must have suitable grasping property between its terminal, just can guarantee to constitute the connection of electric circuit.

Especially; known board to board connector only is that the solder side by each terminal welds mutually with the circuit junction of circuit board; and do not have connected structure between other and the circuit board; therefore regular meeting substitutes in the plug of carrying out circuit board; or being subjected to external force between circuit board does the time spent; its active force will produce terminal and pull, and will cause terminal and circuit junction to be separated, cause can't holding circuit normal operation.

Technology contents

Main purpose of the present utility model provides a kind of improved terminal structure of board to board connector, substitute in the plug of carrying out circuit board to solve, or being subjected to external force between circuit board does the time spent, its active force produces terminal and pulls, and will cause terminal and circuit junction to be separated, cause the problem of normal operation that can't holding circuit.

The technical solution of the utility model is:

A kind of improved terminal structure of board to board connector, its connector is by connecting bull and being connected parent part institute sleeve be combined into, it connects bull is to set firmly mutually with the circuit board of desiring to connect respectively with connecting parent part, and be provided with the terminal that can engage in sleeve male seat and the sleeve female seat of sleeve mutually connecting bull and connection parent part, and this terminal respectively with the board circuit contact Joint that is connect, and then the electric circuit that constitutes two circuit boards connects; Wherein: this terminal on the faying surface corresponding be provided with connect bull with connect parent part can form comparatively firm overlap joint effect during sleeve mutually and make connect bull and the sleeve that is connected parent part have the paragraph corrective action can be involutory mutually protuberance reach plural at least draw-in groove.

The utility model is by corresponding protuberance and the plural at least draw-in groove of being provided with on connecting bull and connecting the terminal faying surface that parent part engaged, to connect bull and connection parent part mutually during sleeve, form comparatively firm overlap joint effect by the involutory of protuberance and draw-in groove, and it is poor by the paragraph between draw-in groove, make the connection bull have the effect that paragraph is adjusted with the sleeve that is connected parent part, with the relative position between further cooperation adjustment circuit board, and more help setting of electric circuit.

And, connecting bull and be connected the Ban Mianchu that parent part and circuit board fit and be provided with metal backing respectively, become the solder side that combines with circuit board with plate face by metal backing, to increase the bond strength that connects bull and connect parent part and circuit board, make whole connector be born bigger plug active force in use; And when plugging when substituting between the circuit board, or circuit board is subjected to external force and does the time spent, its active force will be unlikely the weld that acts directly on terminal, but the meeting average mark is dissipated to the weld of metal backing and circuit board, effectively avoid the disengaging of terminal and circuit junction, with the connection of certain formation electric circuit.
