Abstract

PURPOSE:To prevent the back coming-off of short connecting terminals by determining arrangement positions for connecting terminals with different lengths, concentrating the short connecting terminals at the center section, providing a recess at the rear section of a housing main body, and coupling a rear holder with this recess. CONSTITUTION:Connecting terminals with a long length and feeding a large- capacity current are inserted into terminal storing holes 2a on the periphery, and connecting terminals 3 with a short length are inserted into terminal storing holes 2b at the center section. The connecting terminals 3 inserted at the center section are short in length, the length of the terminal storing holes 2b of a housing main body 1 can be made short, the whole rear section is formed into a recess 4, and the opening sections of the terminal storing holes 2b are faced to the recess 4. A rear holder 5 formed into a lattice shape is coupled and fixed to the recess 4. The back coming-off of the inserted connecting terminals 3 can be prevented without changing the size of the housing main body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connector housing for accommodating a plurality of connection terminals of different lengths in a mixed manner.

[Prior Art] Conventionally, a connector housing in which connection terminals of different lengths are accommodated in one connector housing is also known. The rear end portions must be approximately aligned, and the rear end portions are not aligned for each connection terminal, resulting in unevenness at the rear of the housing, resulting in poor assembly efficiency and an unsightly appearance.

[Problems to be Solved by the Invention] An object of the present invention is to determine the placement positions for connection terminals of different lengths, to concentrate short connection terminals in the center, and to provide a recess at the rear of the housing body. An object of the present invention is to provide a connector housing that prevents short connection terminals from coming off later by fitting a rear holder into the connector housing.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the connector housing according to the present invention, a plurality of connection terminals having different lengths are mixed and each terminal receiving hole is provided in the housing body. a long connection terminal is arranged around the housing body, a short connection terminal is arranged in the center part, and the opening of the terminal receiving hole in the center part at the rear of the housing body A recess is formed by recessing inward from the opening of the housing hole, and a rear holder is fitted into the recess for locking the rear part of the connecting terminal to be stored in the central terminal housing hole. It is.

[Function] In the connector housing having the above-described configuration, a short connection terminal is arranged in the center of the housing body, a recess is provided at the rear of the short connection terminal, and a rear holder for removing the connection terminal is fitted into the recess.

[Example] The present invention will be explained in detail based on illustrated embodiments.

In FIG. 1, ▪ is a housing body, and this housing body 1 is provided with a large number of terminal accommodating holes. In particular, the surrounding terminal receiving holes 2a have a long length (connecting terminals through which a large capacity current flows), which are advantageous for heat dissipation, and the central terminal receiving holes 2b have a relatively small capacity and a long length. A short connecting terminal 3 as shown in FIG. 2 is inserted.Since the connecting terminal 3 inserted into the center is short, the length of the terminal receiving hole 2b in the housing body 1 is also short.
The entire rear part is a recess 4, and the opening of the terminal receiving hole 2b faces into the recess 4. A barrier holder 5 configured in a lattice shape is fitted and fixed in this recess 4. In this case, the axis of the terminal accommodating hole 2b and the axis of the hole 5a of the rear holder 5 are slightly shifted, for example, in the vertical direction, and the rear end of the connecting terminal 3 inserted into each terminal accommodating hole 2b in the center. part, the lattice part 5b of this rear holder 5
These are fixed respectively to prevent the connecting terminals 3 from coming off later. Further, the rear holder 5 is provided with a claw portion 5c of a locking mechanism for the housing body I, and the like. A lock portion 6 is formed in the upper part of the housing body 1, and locking is performed when the connector is fitted with a mating housing, thereby connecting the connectors to each other.

In use, the electric wire 7 connected to the rear crimp portion of the connecting terminal 3 is inserted through each hole 5b of the rear holder 5, and then the connecting terminal 3 is fixed to the tip of the electric wire 7. After the connecting terminals 3 are inserted into the individual terminal receiving holes 2b, the rear holder 5 is shifted relative to the electric wire 7 and then fitted and fixed in the recess 4. Of course, as shown in FIG. 3, each terminal receiving hole 2b of the housing body l is provided with a locking part 1a, such as a case lance, for fixing the connecting terminal 3. A proper lock is made. In this state, since the terminal receiving hole 2b and the hole 5a of the rear holder 5 are slightly shifted in the vertical direction, the lattice part 5b of the rear holder 5 engages with the rear end 3a of the connecting terminal 3, and the connecting terminal This prevents falling behind.

When the rear holder 5 is fitted into the housing body 1,
The rear surface of the housing is substantially flat. Further, the mating housing 8 is fitted, and the connecting terminals are connected to each other.

[Effects of the Invention] As explained above, the connector housing according to the present invention has a recess formed in the central rear part of the housing main body, and by fitting the rear holder into this recess, the connector housing can be inserted without changing the size of the housing main body. It is possible to prevent the connection terminal from falling out later.
