Abstract

The utility model relates to the computer accessory technical field, in particular to an electric connector which comprises a casing and a connecting terminal, wherein the connecting terminal is inserted in a mounting groove of the casing. The characteristics are that the upper portion of the connecting terminal is an S-shaped external contact portion, the lower portion is connected with a horizontal welding leg, inserting ports are arranged on the outer surface of the two lateral sides of the casing, one right angle plate of a mounting plate which takes on a right angle is inserted in the inserting port, and the middle portion of the other right angle plate is provided with through-holes, the right angle plate and the welding leg are located on a same plane, a supporting wall on the casing which is used to place the welding leg of the connecting terminal is a horizontal supporting wall. The advantages are that the location between the electric connector and a circuit board is firm, the electric connection property of the connecting terminal is excellent, and the electric connector is suitable to be used by electric connectors with various types.

Description

Electric connector

Technical field:

The utility model relates to the computer fittings technical field, refers in particular to a kind of electric connector.

Background technology:

Along with progress of science and technology, electronic product is as industry with the fastest developing speed, can be described as with rapid changepl. never-ending changes and improvements, the update cycle of product is shorter and shorter, yet, accessory product---electric connector as electronic product, because existing electric connector is directly to be welded on the metallic plate on the electric connector on the circuit board with being connected of circuit board, if the metallic plate on the electric connector and the not prison welding of scolding tin, just make electric connector loosening easily, cause the loose contact that is electrically connected, even open circuit, in addition, the binding post of existing electric connector mostly adopts the design of U type, because its elasticity leeway is little, if plug plug repeatedly, the bad phenomenon of contact is taken place, directly influence the operate as normal of electronic product.

Summary of the invention:

The purpose of this utility model provides a kind ofly can reliably weld and contact good electric connector with circuit board.

The utility model is achieved in that electric connector, include housing and binding post, binding post inserts in the mounting groove of housing, the top that it is characterized in that described binding post be a S shape to outside contact part, the bottom links to each other with the leg of level, two side external surfaces at housing are provided with interface, a L-square of one rectangular mounting panel inserts in the interface, the middle part of another L-square of mounting panel offers through hole, this L-square and leg are in the same plane, and the supporting walls of taking the leg of putting binding post on housing is the supporting walls of a level.

The both sides of the right-angle side on the mounting panel in above-mentioned insertion interface are provided with the projection with housing location usefulness, and the groove of projection is held in corresponding being provided with in the interface of housing.

Through hole on the above-mentioned mounting panel has certain tapering, and is less with the aperture of the contacted side of circuit board.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model is owing to offer through hole at the middle part of the mounting panel that welds together with circuit board, and it is less with the aperture of the contacted side of circuit board, after scolding tin welds by above-mentioned through hole and circuit board, solder joint has also just been located the upper and lower of mounting panel and position, front, rear, left and right, even if solder joint and mounting panel not prison welding have the solder joint of tapering can play positioning action preferably in the same old way.

2, the binding post of the utility model S shape of adopting makes the interval of strain of binding post bigger, and the elastic energy of storage is also just bigger, make binding post to connect electrical property good.

3, the utility model is suitable for doing the electric connector usefulness of various models.

Embodiment:

With specific embodiment the utility model is further described below:

Referring to Fig. 1-7: electric connector, include housing 10 and binding post 20, binding post 20 inserts in the mounting groove 102 of housing 10, the top that it is characterized in that described binding post 20 be a S shape to outside contact part 201, the outer end to outside contact part 201 of S shape is one cambered outwards protruding 2011, the bottom links to each other with the leg 202 of level, two side external surfaces at housing 10 are provided with interface 104, a L-square 303 of one rectangular mounting panel 30 inserts in the interface 104, the middle part of another L-square 301 of mounting panel 30 offers through hole 2011, this L-square 301 is in the same plane with leg 202, and the supporting walls 103 of taking the leg 202 of putting binding post 20 on housing 10 is the supporting walls of a level.

The both sides of the right-angle side 303 on the mounting panel 30 in above-mentioned insertion interface 104 are provided with the projection 3031 with housing 10 location usefulness, and the groove of projection 3031 is held in corresponding being provided with in the interface 104 of housing 10.

Through hole 3011 on the above-mentioned mounting panel 30 has certain tapering, and is less with the aperture of the contacted side of circuit board.

Use of the present utility model: earlier with wiring place corresponding on the one side alignment circuit plate of leg 202 of the present utility model and L-square 301, the through hole 3011 usefulness scolding tin that see through on the L-square 301 weld together L-square 301 and circuit board, again circuit corresponding on leg 202 and the circuit board is welded together, can insert in this electric connector from the front with integrated package 101 or company's plug, with corresponding binding post electrical connection.

The utility model is suitable for doing the electric connector usefulness of various models.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection range of the present utility model.
