Description

Jig

Technical field

The utility model relates to modeling tool field, in particular to a kind of jig.

Background technique

Current electronic workpiece, such as filter, generally require and are electrically connected with external equipment, in order to make electronics work Part is electrically connected with external equipment, and mounting hole can be generally opened up on the shell wall of electronic workpiece, then utilizes external tool Connector is pressed into mounting hole, after connector is pressed into mounting hole, connector and electronic workpiece are electrically connected, in actual conditions In, generally it can facilitate external tool that connector is pressed into mounting hole, in actual conditions using the fixed electronic workpiece of a jig In, jig generally comprises: the shell wall of backboard, the fixing piece being arranged on backboard, fixing piece and electronic workpiece supports, due to electronics Workpiece usually utilizes mold to manufacture, so there is inclined draft angle on shell wall, and fixing piece is with the face that shell wall supports One plane, therefore cannot be bonded completely between fixing piece and shell wall, and the shell wall of electronic workpiece is generally very thin, works as fixing piece It cannot be bonded completely with shell wall, and after connector is pressed into mounting hole by external tool, pressing force will lead to electronic workpiece Shell wall deformation, so that electronic workpiece be damaged.

Utility model content

The purpose of this utility model is to provide a kind of jig, so that external tool is when connector to be pressed into mounting hole, Electronic workpiece will not be damaged.

In order to solve the above technical problems, the embodiments of the present invention provides a kind of jig, the jig is for fixing Electronic workpiece, electronic workpiece include: shell bottom, several shell walls being arranged on shell bottom, and each shell wall on shell bottom for surrounding For placing the inner cavity of the component of electronic workpiece, at least one mounting hole is opened up on any one shell wall, each mounting hole is equal For erection joint, in addition, specifically, jig includes: backboard and fixing piece, wherein backboard is for resisting each shell wall away from shell Backboard is arranged in towards the side at shell bottom in the side at bottom, fixing piece, for being inserted into the inner cavity of electronic workpiece, and is used for and electronics The side shell wall that workpiece offers mounting hole fits closely.

Present embodiment in terms of existing technologies, since fixing piece and electronic workpiece offer the side shell of mounting hole Wall fits closely, therefore when connector is pressed into mounting hole by external tool, and fixing piece can be bonded completely with shell wall, thus It can avoid damaging electronic workpiece.

Further, open up the shell wall of the mounting hole towards the inner cavity side be from shell bottom direction to described interior Cavity direction is towards deviating from inclined first inclined-plane of interior cavity direction, and the face that the fixing piece is bonded with first inclined-plane is with described the The second inclined-plane that one inclined-plane mutually agrees with.

Since the draft angle of electronic workpiece shell wall is usually to tilt from shell bottom direction to interior cavity direction towards away from interior cavity direction The first inclined-plane, therefore, in order to be bonded completely with the first inclined-plane, face that fixing piece is bonded with the first inclined-plane is and the first inclined-plane phase The second inclined-plane mutually agreed with is bonded between shell wall and fixing piece completely to can guarantee.

Further, the fixing piece includes: several convex blocks set gradually, and between two convex blocks of arbitrary neighborhood The region for being spaced from each other, and separating and to open up the position of the mounting hole on the shell wall corresponding, and connect with the mounting hole It is logical；

Wherein, region spaced apart from each other is used to be pressed into the peace in the connector between two convex blocks of arbitrary neighborhood It when filling hole, is inserted by the connector, the side that each convex block is used to resist the shell wall together constitutes with second inclined-plane.

Further, each convex block is arranged perpendicular to the backboard.

Further, jig further include:

Limit plate is set on the backboard, is spaced from each other with the fixing piece, and is parallel to the fixing piece；

Wherein, the limit plate opens up the mounting hole side for cooperating the fixing piece to clamp the electronic workpiece Shell wall, and the limit plate is also used to be pressed into the predeterminated position of the mounting hole in the connector away from the side of the fixing piece When resist the tooling for pressing the connector.

Tooling is limited by limit plate, connector can be prevented to be pressed into too low.

Further, the limit plate also opens up recessed for being positioned to the connector away from the side of the backboard Slot.It is positioned by groove butt joint, so that connector can be accurately pressed into mounting hole.

Further, the slot bottom of the groove is the cambered surface agreed with the joint surface.

Further, the side that the limit plate is used to resist the shell wall is a flat surface.

Further, the limit plate is detachably connected with the backboard, since limit plate and backboard are detachably connected, because This can be adjusted, so that making for jig can be improved when the depth depth difference that connector needs to be pressed by replacement limit plate Use convenience.

Further, the jig further include: bottom plate is connect with the backboard, is used to support the backboard.
